Description

  The present invention relates to an oral cleaning material holder and an oral cleaning material holder with an oral cleaning material, and more particularly to an oral cleaning material holder including a Y-shaped movable member and an oral cleaning material holder with an oral cleaning material.

  Conventionally, it is provided with a main body which is integrally formed with a handle which is Y-shaped and has a base which is a base and a pair of arms which are bifurcated from the handle, and a cord-like or belt-like shape between the arms. There is an oral cleaning material holder that can stretch an oral cleaning material forming a stretched body.

  In a conventional oral cleaning material holder, a band-shaped sheet-like material is formed into a cylindrical shape to form an oral cleaning material, and a pair of arms are fitted into the cylindrical inner peripheral portion to attach a stretched body. There is one that is used as a tongue coating / plaque cleaning material holder for removing tongue coating and plaque (Patent Document 1).

  That is, in the conventional tongue coating / plaque cleaning material holder, the pair of arm portions have an elastic force to the outside, and after being fitted into the cylindrical oral cleaning material, the biasing force to the outside The oral cleaning material is supported. In addition, the oral cleaning material can be removed by deforming the pair of arm portions inward. Therefore, the conventional tongue coating / plaque cleaning material holder can be detachably mounted with the oral cleaning material, and the oral cleaning material can be replaced after tongue coating or plaque accumulates by cleaning. As a result, the conventional tongue coating / plaque cleaning material holder can be used repeatedly over and over even after cleaning the tongue coating and plaque multiple times.

  A conventional tongue coating / plaque cleaning material holder must be securely held so that the oral cleaning material is not pulled out by the pair of arm portions even in use. At this time, the conventional tongue coating / plaque cleaning material holder is stretched by internally fitting the pair of arm portions to the inner peripheral portion of the cylindrical oral cleaning material using a belt-shaped sheet material. Sufficient friction must be generated between the inner peripheral portion of the oral cleaning material and each of the arm portions to hold the oral cleaning material in the direction in which the oral cleaning material is pulled out of the pair of arm portions. I must. As a result, the strip-shaped sheet material needs to have a width that can cause the friction in the axial direction of the cylindrical shape.

  Therefore, in the conventional tongue coating / plaque cleaning material holder, the oral cleaning material will have a width that can produce the frictional force, and by replacing the oral cleaning material once, the area of that area The sheet material must be consumed, which is uneconomical.

  Moreover, in order to form the said oral cleaning material, the said sheet material material must be shape | molded in a cylindrical shape each time, The process for that is required.

  Further, in order to remove the oral cleaning material from the conventional tongue coating / plaque cleaning material holder, an operation for deforming the pair of arm portions inward is required. When pressing the pair of arms from above the cleaning material, the used oral cleaning material must be touched.

  On the other hand, in the conventional floss holder, the base portion of the Y-shaped movable member is longer than each of the second arm portions. Therefore, in order to change the movable member to a state in which the dental floss is sandwiched from the state in which the dental floss is released, the user holds the main body with one hand while supporting the conventional floss holder. If the movable member is not grasped and operated with the other hand, it is difficult. For this reason, it is difficult to use both of the user's hands to put the dental floss in a state where the dental floss is released.

  By the way, the dental floss is stored in a dedicated case in a wound state, and is exposed in a state where at least a part thereof is unwound. Then, the user switches the floss holder to a state in which the dental floss is sandwiched, so that each first arm portion and each second arm portion facing each other sandwich the exposed dental floss. .

  For example, the dental floss is accommodated inside a box-like case that is flat in the front-rear direction and wound around a core that is rotatably supported by a support shaft in the front-rear direction. This case can be exposed by extending a part of the dental floss out of the case.

  The user performs an operation of sandwiching the exposed dental floss with a floss holder.

  At this time, it is difficult for the user to use both hands of the user for the operation to change the dental floss from the state in which the dental floss is released with the conventional floss holder. It is difficult to support the dental floss to be pinched with one hand or to carry out the dental floss from the case.

  In view of such a problem, the present invention provides an oral cleaning material holder that can easily put the oral cleaning material from a state in which the oral cleaning material is released while economically consuming the oral cleaning material, and An object of the present invention is to provide an oral cleaning material holder with an oral cleaning material that can easily hold the oral cleaning material again from a state in which the oral cleaning material is released.

(1) A Y-shaped body including a main body integrally including a handle that is a base portion thereof and a pair of first arm portions that are bifurcated from the handle, and between the first arm portions. And an oral cleaning material holder capable of stretching an oral cleaning material forming a string-like or belt-like stretched body, which is Y-shaped on one side of the main body and is a base portion thereof. A movable member integrally including a movable member base and a pair of second arm portions bifurcated from the movable member base; the movable member base being shorter in length than the second arm portion; The member rotates around a rotation axis connecting the first arm portions, and the first arm portion and the second arm portions facing each other sandwich both ends of the oral cleaning material. Providing an oral cleaning material holder characterized in that it is possible A.

  That is, in the oral cleaning material holder of the present invention, one end of the oral cleaning material is sandwiched between one of the first arm portion and one of the second arm portions, and the other end of the oral cleaning material. Is sandwiched between the other first arm portion and the other second arm portion. Therefore, each end of the oral cleaning material is firmly sandwiched and held between each of the first arm portions and each of the second arm portions opposed to the first arm portions. It is not necessary to have a large width like the oral cleaning material mounted on the dirt cleaning material holder. Thus, the oral cleaning material holder of the present invention consumes the oral cleaning material economically.

  Moreover, it is not necessary to shape | mold the said oral cleaning material in the shape like the said cylindrical shape, for example, and the process for that is not required and it is economical.

  By the way, since the movable member base is shorter than each of the second arm portions, the movable member is movable from the rotation axis as compared with the case where such a movable member base is longer than the second arm portion. The distance to the end of the member base is short. Therefore, in order to place the oral cleaning material holder of the present invention in the clamping state in which the oral cleaning material is sandwiched, the user holds the body with one hand and supports the oral cleaning material holder while maintaining the same. It is easy to rotate the movable member so that the movable member is pulled toward the near side with the fingers of the hand.

  Therefore, when the user operates with either one of the hands, the oral cleaning material holder can be changed from the released state where the oral cleaning material is easily released to the sandwiched state.

(2) In the oral cleaning material holder of the present invention, the movable member can release the held oral cleaning material from the respective arm portions by rotation in the direction opposite to the rotation around the rotation axis. May be.

  That is, the oral cleaning material holder of the present invention can release the oral cleaning material by operating the movable member, so that it is not necessary to touch the used oral cleaning material for the operation. Thereby, operation can be performed cleanly.

  In order to release the oral cleaning material holder of the present invention, the user holds the main body with one hand and supports the oral cleaning material holder, while facing the movable member with fingers of the same hand. It can be rotated to push it to the side. Therefore, when the user operates with one of the hands, the oral cleaning material holder can be easily released from the sandwiched state.

(3) The oral cavity cleaning material holder of the present invention has an engaging means for detachably engaging the main body and the movable member, and the movable member base is rotated by rotating around the rotation axis. It may be engaged with the main body, and each of the arm portions may be capable of holding the oral cleaning material in the engaged state.

  That is, the oral cleaning material holder according to the present invention is capable of holding the oral cleaning material in a state where the arm portions are in the engaged state, so that the user's oral cavity such as a tongue or a tooth during use of the oral cleaning material. Even when an external force is applied by an internal part or the like, the oral cleaning material is prevented from being pulled out by deformation.

  In addition, the user can easily clean the teeth with one hand by holding the movable member to the main body and holding the oral cleaning material holder in a sandwiched state. Furthermore, the movable member base can be detached from the main body, and the oral cleaning material holder can be released to prepare for the next use.

(4) In the oral cleaning material holder of the present invention, the tip of each first arm and the tip of each second arm are opposite to the handle and the movable member base with respect to the rotation axis, respectively. The first arm part and the second arm part, which are located on the side and face each other, are cleaning material sandwiching parts in the first arm part provided between the tips and the rotation axis, respectively. The oral cleaning material may be clamped between a certain first cleaning material clamping part and a second cleaning material clamping part which is a cleaning material clamping part in the second arm part.

  That is, the first cleaning material sandwiching portion is located on the opposite side of the handle with respect to the rotation axis, and the second cleaning material sandwiching portion is located on the opposite side of the movable member base with respect to the rotation axis. Therefore, when the movable member is rotated and the movable member base is pushed down so as to approach the main body, the second cleaning material sandwiching portions rotate around the rotation axis, and are lifted up. The first cleaning material sandwiching portion is approached. On the other hand, when the movable member is rotated in the reverse direction and the movable member base is lifted away from the main body, the second cleaning material clamping portions are rotated about the rotation axis. And then moves away from each of the first cleaning material sandwiching portions.

  Thereby, an oral cleaning material can be pinched | interposed between the front-end | tip of each said arm part, and the said rotating shaft line. Therefore, the user does not arrange the oral cleaning material in front of the rotation axis and between the main body and the movable member to sandwich the oral cleaning material, but on the opposite side of the rotation axis. It arrange | positions between the said main body and the said movable member.

  Therefore, the oral cleaning material holder of the present invention, for example, when the oral cleaning material is applied to a part such as a tongue, gums, or teeth, the arm portions may protrude in a direction closer to the part than the oral cleaning material. There are few, and each said arm part does not become obstructive, and can clean these parts efficiently.

  Moreover, since the user arranges the oral cleaning material on the opposite side of the rotation axis, for example, the oral cleaning material that has been previously drawn out from the case and exposed can be picked up by each of the cleaning material sandwiching portions. At this time, the user can bring the oral cleaning material closer to the oral cleaning material from the distal end side of the arm portion, and can easily pick it up. That is, the oral cleaning material can be sandwiched without separating the finger that rotates the movable member from the movable member and introducing the oral cleaning material between the main body and the movable member.

  Therefore, the user can easily hold the oral cleaning material by the oral cleaning material holder of the present invention.

(5) The oral cleaning material holder of the present invention is an oral cleaning material holder capable of stretching a plurality of the oral cleaning materials between the first arm portions, and each of the first cleaning materials. The distal end of the arm portion and the distal end of each of the second arm portions are located on the opposite sides of the handle and the movable member base with respect to the rotational axis, respectively, The 2nd arm part is the cleaning in the 1st cleaning material clamping part which is the cleaning material clamping part in the 1st arm part provided between the each above-mentioned tip and the axis of rotation, respectively, and the 2nd arm part The oral cleaning material on the distal end side can be sandwiched between a second cleaning material sandwiching portion that is a material sandwiching portion, and a first provided between the rotation axis and the handle or the movable member base, respectively. The cleaning material clamping part in the arm part of the third A cleaning substrate sandwiching unit, the oral hygiene material of the handle side may be sandwiched between the fourth cleaning substrate sandwiching portion is a cleaning material sandwiched portion of the second arm portion.

  That is, the oral cleaning material holder of the present invention sandwiches the distal-side oral cleaning material that is the oral cleaning material disposed on the distal side and the handle-side oral cleaning material that is the oral cleaning material disposed on the handle side. Since it is possible, the site | part in an oral cavity can be cleaned with these two steps | paragraphs of oral cleaning materials. Thereby, cleaning can be performed efficiently.

  Then, by rotating the movable member, the distal-side oral cleaning material and the handle-side oral cleaning material can be brought into a sandwiched state from a released state by one operation. Similarly, by rotating the movable member in the opposite direction, the distal-side oral cleaning material and the handle-side oral cleaning material can be brought into a released state from a sandwiched state by a single operation. Thereby, the oral cleaning material holder of this invention can be made into the state which clamps an oral cleaning material easily from the state which released the oral cleaning material, and is easily oral cavity cleaning material from the state which clamped the oral cleaning material. Can be released.

(8) In the oral cleaning material holder of the present invention, the distal-side oral cleaning material may be dental floss, and the handle-side oral cleaning material may be a belt-shaped mesh.

  That is, the oral cavity cleaning material holder of the present invention can clean a site in the oral cavity with the dental floss on the tip side and the belt-like mesh on the handle side. Thereby, one oral cleaning material holder can be used for both the cleaning between the teeth by the dental floss and the cleaning of the tongue by the belt-shaped mesh, and an efficient cleaning can be performed.

  Further, by rotating the movable member, the dental floss on the distal end side can be brought into a sandwiched state from the released state, and the belt-like mesh on the handle side can be brought into a sandwiched state from the released state. . Similarly, by rotating the movable member in the opposite direction, the dental floss can be changed from the pinched state to the released state, and the belt-shaped mesh can be changed from the pinched state to the released state.

(9) In the oral cleaning material holder of the present invention, the belt-shaped mesh may have an opening penetrating in the sheet thickness direction.

  That is, since the belt-like mesh has the opening, the tongue coating that is a dirt adhering to the thread-like nipple on the surface of the tongue can be applied to the opening and scraped off. Thus, the site | part in an oral cavity can be cleaned efficiently. Moreover, when the tip of the tongue coating is small enough to be positioned in the opening, cleaning can be performed more efficiently.

  Furthermore, since the opening penetrates in the sheet thickness direction, the band-shaped mesh can be easily washed by pouring running water, washing water or the like after cleaning the dirt.

(10) In the oral cleaning material holder according to the present invention, when the movable member rotates in the opposite direction, a straight line connecting the counter-rotation axis side end of the movable member base and the rotation axis and the longitudinal direction of the main body May be rotatable within a range of an opening angle of less than 90 degrees.

  That is, since the movable member does not rotate more than 90 degrees, the user can easily rotate the movable member so that the movable member can be pulled toward the near side by fingers and can be rotated so as to push it away. Can be made. By these, the user can easily change the oral cleaning material holder from the released state to the held state, and can change the held state from the held state to the released state.

(11) In the oral cavity cleaning material holder according to the present invention, the movable member can be moved in both forward and reverse directions by operating the movable member base using the thumb of the one hand while the user holds the body with one hand. It may be pivotable.

  That is, since the user can operate the movable member base with the thumb of the hand on the side holding the main body, for example, compared with the case where the movable member is rotated by the index finger or the middle finger of the same hand, The movable member can be rotated while the index finger or the middle finger is used to hold the main body. Thereby, it is possible to easily operate the movable member in a state where the oral cleaning material holder is supported in a well-balanced manner.

(12) In the oral cleaning material holder of the present invention, the sandwiching edge of each of the first cleaning material sandwiching portions and the sandwiching edge of each of the second cleaning material sandwiching portions are each linear when viewed in the rotational axis direction. And the oral cleaning material is sandwiched from both sides toward the center of the cross section, and either one or both of the first cleaning material clamping portion and the second cleaning material clamping portion are Bending toward the cleaning material sandwiching portion, and the sandwiching edge of the first cleaning material sandwiching portion and the sandwiching edge of the second cleaning material sandwiching portion sandwich the oral cleaning material In this case, they may be positioned so as to be substantially parallel.

  That is, the oral cleaning material holder of the present invention is positioned so that one clamping end edge and the other opposing clamping edge are substantially parallel in the state of sandwiching the oral cleaning material, for example, When an oral cleaning material having a substantially rectangular cross section such as a band-shaped mesh is sandwiched, force can be applied evenly over the entire long side of the substantially rectangular cross section. Thereby, for example, even when the oral cleaning material is stretched by strongly applying the oral cleaning material to parts such as the tongue, gums, and teeth, the oral cleaning material is displaced from the sandwiching edge at a part of the long side of the transverse section. And can be used easily.

  Further, for example, a string-like oral cleaning material such as dental floss can be sandwiched from two directions opposed to the center of the transverse section by 180 degrees and in a direction substantially orthogonal to each of the sandwiching edges. Is possible. Therefore, for example, the mouth cleaning material does not slide in the cross-sectional direction while being sandwiched and does not fall out of the mouth cleaning material holder of the present invention, and can be easily sandwiched.

  Further, even after the oral cleaning material is once sandwiched by the respective cleaning material sandwiching portions, the frictional force is applied substantially uniformly in the direction of the sandwiching edge, so that the oral cleaning material is displaced from the oral cleaning material holder of the present invention and falls off. And can be used easily.

(13) The present invention includes a main body which is integrally formed with a handle which is Y-shaped and has a base which is a base and a pair of first arms which are bifurcated from the handle, and each of the first arm portions. An oral cleaning material holder with an oral cleaning material in which an oral cleaning material that forms a string-like or belt-like stretched body is stretched between each other, and is Y-shaped on one side of the main body, and A movable member integrally including a movable member base that is a base thereof and a pair of second arm portions that are bifurcated from the movable member base, and the movable member base is longer than the second arm portion. The movable member rotates around a rotation axis connecting the first arm portions, and the first arm portion and the second arm portions facing each other are used for cleaning the oral cavity. While sandwiching both ends of the material, the opposite direction of rotation around the rotation axis By the movement, the movable member releases the sandwiched oral cleaning material from each arm portion, and rotates in both forward and reverse directions by operating the movable member base using the thumb of the hand on the side that holds the main body. The present invention provides an oral cleaning material holder with an oral cleaning material, which is movable.

  That is, the user can release the oral cleaning material such as dental floss and band-shaped mesh from the oral cleaning material holder with oral cleaning material such as the floss holder with dental floss and the mesh holder with band-shaped mesh of the present invention. The thumb of the hand gripping the hand can be rotated to push the movable member away from it, and the mouth cleaning material holder is sandwiched again by the mouth cleaning material holder. The movable member can be pivoted so as to be pulled toward the near side with the thumb of the hand. Thereby, it is possible to easily operate the movable member in a state where the oral cleaning material is supported with a good balance by one hand.

(14) In the oral cleaning material holder with the oral cleaning material according to the present invention, the tip of each of the first arm portions and the tip of each of the second arm portions are respectively the handle and the movable with respect to the rotation axis. The first arm portion and the second arm portion that are located on the opposite side of the member base and face each other are cleaned in the first arm portion provided between the tip and the rotation axis, respectively. The oral cleaning material may be sandwiched between a first cleaning material sandwiching portion that is a material sandwiching portion and a second cleaning material sandwiching portion that is a cleaning material sandwiching portion in the second arm portion.

  In the floss holder 1, the movable member 3 is disposed on the lower side D of the main body 2, and rotates around the rotation axis Cr as shown in FIG. 2. At this time, the movable member 3 rotates so as to be displaced to the near side UB that is closer to the main body 2 and the far side DT that is farther from the main body 2.

  The user of the floss holder 1 supports the floss holder 1 with one hand H1. At this time, the user holds the main body 2 with three fingers including, for example, the thumb F1, the ring finger F4, and the little finger F5, and draws the movable member 3 toward the near side UB with two fingers including the index finger F2 and the middle finger F3. And can be operated by rotating in the opposite direction so as to push away to the other side DT.

  The main body 2 is substantially rectangular when viewed from the front, is Y-shaped when viewed from the top, and integrally includes a pair of main body arm portions 4 and 5 that are bifurcated from the handle 2a that is the base thereof toward the tip T. . As shown in FIG. 1A, the pair of main body arm portions 4 and 5 includes a left main body arm portion 4 that is a left main body arm portion and a right main body arm portion 5 that is a right main arm portion. . The shape of the main body 2 is symmetrical with respect to the center line Cl of the floss holder 1. The handle 2a extends linearly from the base of the main body arm portions 4 and 5 to the base end 2b of the main body 2 and is gripped by the user's fingers F1, F4 and F5.

  The movable member 3 is Y-shaped in a plan view, and integrally includes a pair of movable arm portions 6 and 7 that are bifurcated from the movable member base portion 3a, which is the base portion, in a front end direction T. The pair of movable arm portions 6 and 7 includes a left movable arm portion 6 that is a left side L movable arm portion and a right movable arm portion 7 that is a right side R movable arm portion. The shape of the movable member 3 is symmetrical with respect to the center line Cl of the floss holder 1. The movable member base 3a connects the left movable arm 6 and the right movable arm 7 in the width direction and is operated by the user's fingers F2 and F3 together with the pair of movable arms 6 and 7. The main body arm portions 4 and 5 are also referred to as first arm portions, and the movable arm portions 6 and 7 are also referred to as second arm portions.

  When the movable member 3 is closed with respect to the main body 2, as shown in FIG. 1A, the left movable arm portion 6 overlaps the lower side D of the left main body arm portion 4 in a plan view, and the right movable arm portion. 7 overlaps the lower side D of the right main body arm portion 5, and the movable member base portion 3a overlaps a lower side D of a part of the handle 2a. Thereby, the Y-shape of the movable member 3 and a part of the Y-shape of the main body 2 overlap in the vertical direction of the floss holder 1.

  The movable member 3 sandwiches the dental floss 8 disposed so as to intersect the arm portions 4, 5, 6 and 7 in a plan view with the main body 2. The dental floss 8 has such a length as to be stretched between the left arm portions 4 and 6 and the right arm portions 5 and 7, and as shown in FIG. The tip ends of the arm portion 4 reach the left side L and the right side R from the arm portions 4, 5, 6 and 7, respectively, and an extra length is left in the left direction L and the right direction R.

  In the bottom view shown in FIG. 3, the Y-shape of the movable member 3 is such that the movable arm portion length Lb, which is the distance from the root to the tip of each of the left and right movable arm portions 6, 7, is from the root of the movable member base portion 3a. The shape is longer than the base length La, which is the distance to the base end 3b. Therefore, the movable member base 3 a is shorter than the left and right movable arm portions 6 and 7.

  Each of the left main body arm portion 4 and the right main body arm portion 5 has floss holding grooves 4a and 5a on the base end 2b side with respect to the rotation axis Cr. Each of the floss holding grooves 4 a and 5 a has a depression D in a downward direction that is smaller than the thickness of the dental floss 8 and is long in the width direction of the floss holder 1.

  Each of the left movable arm portion 6 and the right movable arm portion 7 has floss holding grooves 6a and 7a on the base end 3b side of the movable member 3 with respect to the rotation axis Cr. Each of the floss holding grooves 6 a and 7 a has a depression in the upward direction U that has a diameter smaller than the thickness of the dental floss 8 and is long in the width direction of the floss holder 1. The dental floss 8 is securely sandwiched between the left and right body arm portions 4 and 5 and the left and right movable arm portions 6 and 7 in the floss sandwiching grooves 4a, 5a, 6a and 7a.

  The left movable arm 6 and the right movable arm 7 are pivotally attached to the left main arm 4 and the right main arm 5, respectively. That is, the left movable arm portion 6 and the right movable arm portion 7 integrally have support shafts 6b and 7b on the rotation axis Cr, and are provided in the left main body arm portion 4 and the right main body arm portion 5, respectively. The support shafts 6b and 7b are loosely fitted in the shaft holes 4b and 5b and are supported by the left and right main body arm portions 4 and 5, respectively.

  With these structures, the movable member 3 rotates with respect to the main body 2 in both forward and reverse directions around the rotation axis Cr passing through the tip of each arm portion 4, 5, 6 and 7 in the width direction of the floss holder 1. be able to.

  Therefore, when the movable member 3 is rotated and closed with respect to the main body 2, the arm portions 4, 5, 6, and 7 are connected to the floss holding grooves 4 a, 5 a, 6 a, and 7 a by the dental floss 8. Both ends can be clamped vertically. Hereinafter, a state in which the movable member 3 is closed and the dental floss 8 is sandwiched is referred to as a sandwiched state. The width of the tip side T of the floss holder 1 is small enough to be inserted into the human mouth M.

  The dental floss 8 constitutes an oral cleaning material that forms a string-like stretched body. That is, the dental floss 8 is a natural fiber or a synthetic fiber for cleaning the oral cavity, and is formed of a single fiber or a string-like body formed of a bundle of a plurality of fibers. Further, the dental floss 8 is stretched between the main body arm portions 4 and 5 by the arm portions 4, 5, 6 and 7 being vertically clamped in the respective floss holding grooves 4a, 5a, 6a and 7a. Forms a stretched body to be laid.

  And the floss holder 1 is also called an oral cleaning material holder that can stretch the dental floss 8 that is the oral cleaning material as described above.

  Such a combination of the floss holder 1 and the dental floss 8 in the sandwiched state is called a floss holder 9 with a dental floss. The user grasps the main body 2 of the floss holder 9 with dental floss with one hand H1, introduces the floss holder 9 with dental floss into the oral cavity M from the distal end T, and teeth with the dental floss 8 held between the teeth. Clean. In addition to cleaning their own teeth, the user may also clean the teeth of others, such as infants and the elderly who need care.

  The floss holder with dental floss 9 is also referred to as an oral cleaning material holder with an oral cleaning material on which the dental floss 8 as the oral cleaning material is stretched.

  Moreover, the dental floss 8 can be released from each of the floss clamping grooves 4a, 5a, 6a, and 7a by rotating the movable member 3 in the opposite direction from the clamping state to open the main body 2. . Hereinafter, a state where the movable member 3 is opened and the dental floss 8 is released is referred to as a released state.

  The user switches the floss holder 1 from the released state to the sandwiched state by hooking the index finger F2 and the middle finger F3, for example, to the released movable member 3 and rotating the movable member 3 so as to draw it toward the near side UB. . Further, the floss holder 1 is switched from the sandwiched state to the released state by rotating the movable member 3 in the sandwiched state so that the movable finger 3 is pushed to the far side DT by the index finger F2 and the middle finger F3.

  At this time, since the base length La is short and the position of the base end 3b is close to the rotation axis Cr, the user can easily release the middle finger F3 while holding the handle 2a with the thumb F1, the ring finger F4, and the little finger F5, for example. The movable member 3 can be hooked on the base end 3b of the movable member 3, and the movable member 3 can be easily rotated by the index finger F2 and the middle finger F3.

  Each arm part 4,5,6,7 has locking surface 4c, 5c which each main body arm part 4,5 faces downward D. As shown in FIG. Each of the movable arm portions 6 and 7 is an opening angle of the movable member 3 with respect to the main body 2, and an opening angle θ1 that is an angle between a straight line connecting the base end 3b and the rotation axis Cr and the longitudinal direction of the main body 2 is 90 degrees. The other side DT has locking surfaces 6c and 7c that are inclined so as to come into contact with the locking surfaces 4c and 5c of the main body arm portions in a state of a smaller angle.

  That is, when the movable member 3 is rotated so as to open with respect to the main body 2 in order to switch from the clamped state to the released state, the main body arm portions 4 and 5 are locked when the opening angle θ1 increases to approach 90 degrees. Since the surfaces 4c and 5c are arranged on the rotation track of the locking surfaces 6c and 7c of the movable arm portions 6 and 7, the opposing locking surfaces 4c, 6c, 5c and 7c come into contact with each other, and the opening angle They are mutually regulated so that θ1 does not exceed 90 degrees.

  The contact angle between the locking surfaces 4c, 6c, 5c, and 7c suppresses the opening angle θ1 to less than 90 degrees, so that the movable member 3 does not rotate too far to the far side DT. That is, the proximal end 3b does not move far from the index finger F2 and the middle finger F3, and the index finger F2 and the middle finger F3 can be hooked on the movable member 3 in the released state, and the movable member 3 is rotated by these fingers. Can be moved.

  With the above configuration, the user can easily hold the floss holder 1 from the released state with one hand H1 without using the other hand H2 (not shown), and easily change from the held state to the released state. can do. Further, the user can easily release the dental floss 8 from the floss holder 9 with the dental floss with one hand H1, and the floss holder 1 after the floss holder 9 with the dental floss has released the dental floss 8. Thus, the dental floss 8 can be easily held again. Once used, the dental floss 8 is released from the floss holder 9 with dental floss, and can be reused by being sandwiched again by the floss holder 1 and can be discarded.

  By the way, the dental floss 8 is wound and accommodated in a case 10 shown in FIG. 4, for example. The case 10 is flat in the front-rear direction from the front to the back of FIG. 4 and has a support shaft 10a provided in the front-rear direction. Further, the winding core 10b around which the dental floss 8 is wound is freely fitted on the support shaft 10a and rotates freely, so that the case 10 can feed the dental floss 8 out of the case from the feeding port 10c.

  The dental floss 8 that is used by being drawn out from the case 10 is generally called a thread-throw type dental floss.

  The user pulls the tip 8a exposed to the outside of the case in advance and is stretched between the left L arm portions 4 and 6 and the right R arm portions 5 and 7 of the floss holder 1. The length of dental floss 8 is fed out of the case 10. In addition, the user supports the floss holder 1 with one hand H1 and supports the case 10 with the other hand H2.

  Thus, the user can easily hold the dental floss 8 fed from the other hand H2 by the floss holder 1 by performing an operation so as to switch from the released state to the holding state by one hand H1. .

  That is, the floss holder 1 can be operated with one hand H1. Therefore, by supporting the case 10 with the other hand H2, for example, the user can easily guide the dental floss 8 to the floss holding grooves 4a, 5a, 6a, 7a, and the dental floss 8 It can be sandwiched between the main body 2 and the movable part 3 when it hangs down straight. The dental floss 8 after being sandwiched is left with a portion stretched between the arm portions 4, 5, 6 and 7 and a portion left in an extra length in the left direction L and the right direction R, and is separated by a cutter or the like. .

  The left floss holding grooves 4a and 6a may be provided with only one of the main body side and the movable side. Further, only one of the right side floss holding grooves 5a and 7a on the main body side and the movable side may be provided. Furthermore, if a gap for securely holding the dental floss 8 is generated, the floss holding grooves 4a, 5a, 6a, and 7a may not be provided.

  5 to 10 illustrate a second embodiment of the present invention. In FIG. 5, reference numeral 11 denotes a mesh holder. The mesh holder 11 is pivotally attached to the main body 12 and the main body 12, and a movable member that can freely rotate around the rotation axis Cr in the width direction located at the tip of the main body 12. 13.

  The movable member 13 sandwiches a belt-like mesh 18 that is a belt-like mesh arranged so that the longitudinal direction intersects with the arm portions 14, 15, 16, and 17 in a plan view with the main body 12. The belt-like mesh 18 has such a length that it is stretched between the arm portions 14 and 16 on the left side L and the arm portions 15 and 17 on the right side R, and as shown in FIG. Reaches the left side L of the left main body arm portion 14 and the left movable arm portion 16 and the right side R of the right main body arm portion 15 and the right movable arm portion 17, and leaves an extra length in the left direction L and the right direction R.

  The band-shaped mesh 18 forms a rectangle in the plan view of FIG. 5, and includes a cleaning portion 18a represented by a solid line in the figure, and a cleaning portion 18a and sandwiching margin portions 18b and 18b continuous on both sides in the longitudinal direction. The left side pinching margin 18 b is sandwiched between the left main body arm portion 14 and the left movable arm portion 16, and the right side R pinching margin 18 b is sandwiched between the right main body arm portion 15 and the right movable arm portion 17. A state in which the movable member 13 is closed and the belt-like mesh 18 is sandwiched is referred to as a sandwiched state. The width on the tip side T of the mesh holder 11 is small enough to be inserted into the human mouth M.

  In addition, the belt-like mesh 18 can be released from each of the arm portions 14, 15, 16, and 17 by rotating the movable member 13 in the opposite direction from the sandwiched state and opening the movable member 13 with respect to the main body 12. Hereinafter, a state where the movable member 13 is opened and the belt-like mesh 18 is released is referred to as a released state. Other configurations are the same as those in the first embodiment.

  Note that the left main body arm portion 14 and the left movable arm portion 16 have a mesh sandwiching step portion 14a that is recessed upward U and a mesh portion that is recessed downward D, respectively, as shown in FIG. You may have the step part 16a so that it may mutually face. Further, the right main body arm portion 15 and the right movable arm portion 17 have a mesh sandwiching step portion 15a recessed upward U and a mesh sandwiching step portion 17a recessed downward D, respectively, closer to the base end 12b side than the rotation axis Cr. You may have so that it may face.

  At this time, the mesh holding step portions 14a, 15a, 16a, and 17a are provided on the straight portions in the longitudinal direction of the respective arm portions 14, 15, 16, and 17, and have substantially the same length as the width of the belt-like mesh 18. . By these, the user can set the aim and can pinch the belt-like mesh 18.

  The band-shaped mesh 18 constitutes an oral cleaning material that forms a band-shaped stretched body. That is, the band-shaped mesh 18 is formed of a plurality of weft-direction synthetic fibers to clean the oral cavity, and is formed of a plurality of weft-direction synthetic fibers or a plurality of weft-direction synthetic fibers and a plurality of weft-directions A strip formed by a bundle of synthetic fibers. In addition, the belt-like mesh 18 is stretched between the arm portions 14 and 15 by the arm portions 14, 15, 16, and 17 holding the pinching margins 18 b and 18 b in the vertical direction. Make up the body.

  And the mesh holder 11 is also called the oral-cleaning material holder which can stretch the belt-like mesh 18 which is the above-mentioned oral-cleaning material. Since the mesh holder 11 of the present invention can stretch the belt-like mesh 18 without being wound twice or triple, a mesh material such as a mesh tape MT described below is economically consumed. Further, if the mesh tape MT is cut into a predetermined length and formed into a single piece, it can be used as it is. For example, it is not necessary to form it into a three-dimensional shape such as a cylindrical shape. Is.

  Such a combination of the mesh holder 11 and the belt-like mesh 18 in the sandwiched state is referred to as a belt-mesh mesh holder 19. The user grasps the main body 12 of the mesh holder 19 with the belt-like mesh with one hand H1, introduces the mesh holder 19 with the belt-like mesh into the oral cavity M from the distal end T, and uses the sandwiched mesh 18 to hold the tongue. Cleaning of the palate, inner cheek, teeth, gums, interdental and other parts of the oral cavity M are performed. In addition to cleaning the site in the mouth M of the user, the user may also clean the site in the mouth M of another person such as an infant or an elderly person who needs care. The mesh holder 19 with a belt-like mesh is also referred to as an oral cleaning material holder with an oral cleaning material on which the belt-like mesh 18 that is the mouth cleaning material as described above is stretched.

  Once used, the belt-like mesh 18 is released from the mesh holder 19 with the belt-like mesh, and can be reused by being sandwiched by the mesh holder 11 again or discarded.

  An enlarged view of the belt-like mesh 18 is shown in FIG. The belt-like mesh 18 has a mesh 103 woven by synthetic fibers 102v and 102h.

  The synthetic fibers 102v and 102h are made of polyethylene terephthalate (PET) as a raw material, and as shown in the enlarged view of FIG. 5 and FIG. 6, the monofilament warp 102v long in the weaving direction V of the strip mesh 18 and the weaving width perpendicular to the weaving direction V And a monofilament weft 102h long in the direction H. Each of the warp yarns 102v and the weft yarns 102h has a circular cross section, and each warp yarn 102v and each weft yarn 102h have the same diameter.

  The raw material of the synthetic fibers 102v and 102h is not limited to polyethylene terephthalate, but may be any synthetic resin that can be spun and woven into the belt-like mesh 18 and does not cause health damage in the oral cavity M. Thermoplastic resins such as polyester resins other than terephthalate, polyamide resins such as nylon, and polyolefin resins may be used. Polyester resin contains polylactic acid.

  The warp yarns 102v and the weft yarns 102h are arranged at the same pitches Pv and Ph as viewed from the mesh thickness direction T perpendicular to the surface of the belt-like mesh 18. Further, the plurality of warps 102v and the plurality of wefts 102h are entangled so as to form 90 degrees with each other and woven into a plain weave.

  The mesh 103 is one unit in the surface direction constituting the belt-shaped mesh 18, and one mesh 103 is a pair of warps 102v, 102v adjacent in the surface direction of the belt-shaped mesh 18, and a pair of adjacent wefts 102h, 102h. The pair of warps 102v, 102v and the opening 103h surrounded by the pair of wefts 102h, 102h. Therefore, in the entire belt-shaped mesh 18, a plurality of meshes 103 are continuous in the weaving direction V and the weaving width direction H.

  In the mesh 103, the warp yarn 102v and the weft yarn 102h overlap in the mesh thickness direction T, so that a three-dimensional structure in the mesh thickness direction T is formed for one mesh 103a.

  That is, each warp yarn 102v and each weft yarn 102h are inclined closer to the mesh thickness direction T with respect to the weaving direction V and the weaving width direction H, respectively. Therefore, in the first corner 106a located at the upper left corner of the rectangular imaginary line representing the mesh 103a as shown in FIG. 6, the weft yarn 102h passes the front side to the left and right and the warp yarn 102v passes the back side up and down. Further, in the second corner 106b located at the upper right corner, the warp yarn 102v passes up and down the front side and the weft yarn 102h passes the back side left and right. Similarly, at the third corner 106c located at the lower right corner and the fourth corner 106d located at the lower left corner, the warp yarn 102v and the weft yarn 102h pass in the same manner as the first corner 106a and the second corner 106b, respectively. .

  Thus, the mesh 103 has a three-dimensional structure formed by the entanglement of the warp yarn 102v and the weft yarn 102h. Such a mesh 103 is continuously arranged on the belt-like mesh 18. Therefore, the belt-like mesh 18 has a three-dimensional structure over the entire surface.

  In each mesh 103, the warp yarns 102v and the weft yarns 102h are arranged at the same pitches Pv and Ph, and the warp yarns 102v and the weft yarns 102h have the same diameter. Therefore, the three-dimensional structure of the belt-like mesh 18 is a structure in which the same or inverted three-dimensional structure as one mesh 103a is repeated on the entire surface.

  Further, each mesh 103 is surrounded by the warp yarn 102v and the weft yarn 102h, and has an opening 103h penetrating the belt-like mesh 18 in the mesh thickness direction T. Therefore, the belt-like mesh 18 has a porous structure in which the openings 103h are uniformly distributed over the entire surface.

  In the belt-like mesh 18, the weaving direction V coincides with the longitudinal direction in FIG. Further, as will be described later, the weaving direction may be 90 degrees different from this, and the width direction H may coincide with the longitudinal direction.

  Even when the belt-like mesh 18 receives a force in the surface direction or the sheet thickness direction T due to friction with a site in the oral cavity M or the like, the belt-like mesh 18 is sandwiched and supported by the arm portions 14, 15, 16, and 17. Therefore, although the belt-like mesh 18 causes a certain amount of elastic deformation, or elastic deformation and plastic deformation, it does not cause a large deformation.

  On the other hand, the cleaning part 18 a of the belt-like mesh 18 is not sandwiched between the arm parts 14, 15, 16, and 17. Therefore, for example, when the belt-like mesh 18 is inserted between the teeth in the oral cavity M, the user can cause the belt-like mesh 18 to enter from the distal end side edge 18c that is the edge on the distal end side of the belt shaped mesh 18. it can.

  The pair of main body arm portions 14 and 15 and the pair of movable arm portions 16 and 17 are small enough to be inserted into the oral cavity M from the user's lips, and the belt-like mesh 18 is vertically and horizontally moved in the user's oral cavity M. Small enough to move. The handle 12a has such a thickness that the user can hold it with fingers.

  With these configurations, the user can grasp the handle 12a with fingers and insert the belt-like mesh 18 into the oral cavity M. In addition, after insertion, the user moves the mesh holder 19 with the belt-like mesh in the surface direction of the belt-like mesh 18, thereby moving the belt-like mesh 18 to the tongue, palate, inner cheek, teeth, gums, interdental, and other parts in the oral cavity M. The surface of each part can be rubbed with either or both surfaces of the belt-like mesh 18 in the state of being applied to the surface.

  Referring to FIG. 7, by rubbing the surface of the tongue or other part in the oral cavity M with the band-shaped mesh 18, the dirt S (not shown) such as a postprandial meal or tongue coating adhering to the surface of each part is removed. How it can be cleaned.

  Since the belt-like mesh 18 has a three-dimensional structure formed by the entanglement of the warp yarns 102v and the weft yarns 102h over the entire surface, the dirt S can be scraped off by the warp yarns 102v and the weft yarns 102h, and It can be deposited on the surface of 102v, the surface of the weft yarn 12h, or the surface of the warp yarn 102v and the surface of the weft yarn 102h.

  As shown in FIG. 7, in one mesh 103a, the belt-like mesh 18 has the first weft yarn 102h (i) passing through the front side in the sheet thickness direction T at the first corner 106a facing downward. The side surface 107ac is exposed on the front side of the figure. Further, the second warp yarn 102v (ii) passing up and down the front side in the sheet thickness direction T at the second corner 106b has a side surface 107ab facing leftward exposed to the front side in the drawing. Similarly, the second weft yarn 102h (ii) and the first warp yarn 102v (i) passing through the front side in the sheet thickness direction T at the third corner 106c and the fourth corner 106d, respectively, left and right and up and down respectively, A side surface 107bc facing upward and a side surface 107cd facing right are exposed on the front side of the figure.

  Each warp yarn 102v (i), 102v (ii) is arranged at the same pitch Pv, each weft yarn 102h (i), 102h (ii) is arranged at the same pitch Ph, and warp yarn 102v (i), 102v (ii) Since the wefts 102h (i) and 102h (ii) are orthogonal to each other, the mesh 103a is formed in a rectangle having the first to fourth corners 106a, 106b, 106c and 106d as vertices.

  The side surfaces 107ab, 107bc, 107cd, and 107ac can scrape the adhering dirt S in the surface direction of the band-shaped mesh 18 by the user rubbing each part in the oral cavity M with the band-shaped mesh 18. Further, the scraped dirt S is deposited on the surfaces of the side surfaces 107ab, 107bc, 107cd, and 107ac.

  The same applies to the case where the belt-like mesh 18 is viewed from the back side in the sheet thickness direction T.

  For example, when the site in the oral cavity M is the tongue, the band mesh 18 scrapes off the tongue moss Sa, which is the dirt S adhering to the filamentous nipple Ma, in the surface direction by rubbing the filamentous nipple Ma present on the surface of the tongue. it can. As shown in the longitudinal sectional end view of FIG. 8, the filamentous nipple Ma forms a substantially conical shape, and one surface of the belt-like mesh 18 can be applied from the tip side thereof.

  FIG. 8 is a view of the mesh holder 19 with a belt-like mesh as viewed in the width direction, and is a view of the mesh 103 of the belt-like mesh 18 as viewed in the weaving direction V. Therefore, the cross sections of the warps 102v, 102v are shown. Each mesh 103 of the belt-like mesh 18 has an opening 103h passing through the belt-like mesh 18 in the mesh thickness direction T between the warps 102v.

  The user scrapes the tongue coating Sa from the filamentous nipple Ma by moving the mesh holder 19 with the strip mesh in the surface direction of the strip mesh 18. At this time, when the user places the mesh holder 19 with a belt-like mesh on the thread-like nipple Ma and reciprocates in the longitudinal direction, for example, the warp moss Sa partly located in the opening 103h passes the warp threads 102v and 102v in the longitudinal direction. Scrape off. When a part of tongue coating Sa is located in the opening 103h of one mesh 103a shown in FIG. 7, the side surface 107cd of the warp yarn 102v (i), the side surface 107ab of the warp yarn 102v (ii), and these side surfaces 107ab and 107cd The outer peripheral surface can scrape the tongue coating Sa in the surface direction of the belt-like mesh 18.

  As described above, since part of the tongue coating Sa is located in the opening 103h, the warp yarn 102v, the weft yarn 102h or the warp yarn 102v and the weft yarn 102h can scrape the tongue coating Sa at a deeper position on the root side of the filamentous nipple Ma. it can. Thereby, tongue coating Sa can be scraped off more efficiently, and the mesh holder 19 with belt-like mesh can clean the dirt S with a small number of scrapings.

  Moreover, by efficiently cleaning the dirt S in this way, it is possible to reduce the damage caused by damaging the tongue surface by the mesh holder 19 with a belt-like mesh.

  In addition, when the user puts the mesh holder 19 with the belt-like mesh on the papilla Ma and moves it only in the proximal direction B, for example, the outer peripheral surface of the warp yarn 102v (i) other than the side surface 107cd and the side surface 107cd scrapes the tongue coating Sa. Can be taken.

  Further, when the user puts the mesh holder 19 with a belt-like mesh against the papilla Ma and reciprocates in the width direction, or moves only in the left direction L or moves only in the right direction R, the weft yarn 102h (i) The side surface 107ac, the side surface 107bc of the weft yarn 102h (ii), or the outer peripheral surface other than the side surfaces 107ac and 107bc can scrape the tongue coating Sa in the surface direction of the belt-shaped mesh 18.

  Further, when reciprocating in an oblique direction or moving only in any direction of the oblique direction, the outer side surfaces other than the side surfaces 107ab, 107bc, 107cd, 107ac and the side surfaces 107ab, 107bc, 107cd, 107ac are tongue coating. Sa can be scraped off in the surface direction of the belt-like mesh 18.

  Even when the tongue moss Sa is large and does not fit in the openings 103h, or when the tongue 103 is not fit in the openings 103h because the openings 103h are small and the mesh 103 is clogged, Since the warp yarn 102v and the weft yarn 102h have a three-dimensional structure due to the entanglement, the outer peripheral surface of the warp yarn 102v, the weft yarn 102h or the warp yarn 102v and the weft yarn 102h exposed to the tongue coating Sa gives frictional force to the tongue coating Sa. Can be added. Thereby, the tongue coating Sa can be scraped off from the filamentous nipple Ma in the direction in which the mesh holder 19 with the strip mesh is moved in the surface direction of the strip mesh 18.

  By the way, many filamentous nipples Ma are adjacent to each other on the entire tongue surface in the left-right and front-rear directions. On the other hand, the belt-like mesh 18 of the mesh holder 19 with the belt-like mesh of the present invention has a mesh 103 adjacent in the longitudinal direction and the width direction. Therefore, by moving the mesh holder 19 with the belt-shaped mesh in the surface direction of the belt-shaped mesh 18, it is possible to efficiently scrape the tongue coating Sa adhering to many filamentous teats Ma at a time.

  Further, since the warp yarns 102v and the weft yarns 102h are synthetic fibers, the belt-like mesh 18 has flexibility and can clean the dirt S following the complicated shape of the tongue surface.

  Furthermore, the wire diameter of the warp yarn 102v and the weft yarn 102h is, for example, about 0.05 mm, and is the wire diameter in a tongue cleaning tool other than the oral cleaning material holder with the oral cleaning material of the present invention, for example, 0.075 mm or more of a brush system. It is thinner than those of 0.1 mm or more of rubber type. Therefore, the oral cleaning material holder with the oral cleaning material of the present invention cleans the dirt S more efficiently than the other tongue cleaning tools and is less damaged by damaging the tongue surface.

  After the dirt S is deposited on the surfaces of the side surfaces 107ab, 107bc, 107cd, 107ac in FIG. 7, the user pours running water, washing water, etc. on the surface of the belt-like mesh 18 and rubs the dirt S to form a mesh. 3 and the belt-like mesh 18 can be washed. That is, the side surfaces 107ab, 107bc, 107cd, 107ac from which the dirt S has been scraped are exposed to the front side, so that the dirt S can be washed away with running water, washing water, etc. from the same side.

  Moreover, since the opening 103h penetrates in the sheet thickness direction T, the dirt S can be easily cleaned. Even if the dirt S accumulates in the opening 103h to cause clogging, the user rinses the dirt S in the opening 103h by pouring running water, washing water, etc. from the surface of the belt-like mesh 18, It can be removed from the mesh 103.

  As described above, the dirt S is scraped off by the side surfaces 107ab, 107bc, 107cd, 107ac of the mesh 103a, and the dirt S is deposited on the surfaces of the side surfaces 107ab, 107bc, 107cd, 107ac. Dirt S can be cleaned. That is, the user prepares a mesh holder 19 with a belt-like mesh including a belt-like mesh 18 having a mesh 103 woven by synthetic fibers 102v and 102h, and holds the mesh holder 11 to guide the belt-like mesh 18 into the oral cavity M. Thus, the dirt S in the oral cavity M can be cleaned by the belt-like mesh 18. Moreover, the user removes the dirt S from the mesh 103 by pouring running water, washing water or the like onto the surface of the belt-shaped mesh 18 while being held by the mesh holder 11, and cleans the belt-shaped mesh 18 after use. be able to.

  Thus, the user can clean the dirt S in the oral cavity M again with the washed belt-like mesh 18. That is, by repeating the cleaning of the dirt S and the removal of the dirt S, the strip mesh 18 can be used a plurality of times. Then, the belt-like mesh 18 after being used once or plural times can be released from the mesh holder 19 with the belt-like mesh and discarded. At this time, since the belt-like mesh 18 can be released by operating the movable member 13, it is not necessary to touch the belt-like mesh 18 after use for the operation. Thereby, operation can be performed cleanly.

  Even when the belt-like mesh 18 is washed and reused, since the belt-like mesh 18 has the opening 103h, running water, washing water, etc. for washing evaporate immediately. Therefore, the belt-like mesh 18 can be easily dried and kept in a hygienic state.

  In FIG. 5, the belt-like mesh 18 is formed and arranged so that the longitudinal direction thereof coincides with the weaving direction V. However, the direction of the strip mesh 18 is not limited to this direction. That is, the belt-like mesh 18 may be formed and arranged such that the woven width direction H coincides with the longitudinal direction, and the weaving direction V is 30 degrees, 45 degrees, 60 degrees with respect to the longitudinal direction. These may be formed and arranged at an angle.

  Even if the warp yarn 102v and the weft yarn 102h are not the same diameter, the diameters of the warp yarn 102v and the weft yarn 102h may be different if the warp yarns 102v have the same diameter and the warp yarns 102h have the same diameter. .

  Further, the transverse cross section of the warp yarn 102v, the weft yarn 102h, or the warp yarn 102v and the weft yarn 102h is not necessarily a circular cross section, and may be an irregular cross section, a square cross section, or the like.

  Furthermore, the woven fabric structure of the warp yarn 102v and the weft yarn 102h may be a twill weave other than plain weave, satin weave, or the like. The belt-like mesh 18 may have another configuration as long as it has the mesh 103 formed by the synthetic fibers 102v and 102h. Moreover, the angle at which the warp yarn 102v and the weft yarn 102h intersect may be an angle other than 90 degrees as long as the mesh 103 can form a three-dimensional structure.

  FIG. 9 shows a modification of the strip mesh 18 in the present embodiment. FIG. 9 is a photomicrograph of product number 4817 of a mesh filter “Tea Road Sharp” (“Tea Road” is a registered trademark) manufactured by Yamanaka Sangyo Co., Ltd. In FIG. 9, reference numerals 108a, 108b, 108c, and 108d denote thermal welding points located at the first to fourth corners 106a, 106b, 106c, and 106d of the mesh 103a, and the meshes at the respective thermal welding points 108a, 108b, 108c, and 108d. The warp yarns 102v (i), 102v (ii) and the weft yarns 102h (i), 102h (ii) constituting 103a are heat-welded with each other in the belt-shaped mesh 18 which overlaps in the sheet thickness direction T. Other configurations are the same as those in the embodiment shown in FIGS. 6 and 7.

  Thus, since the warp yarn 102v and the weft yarn 102h are heat-welded, when the belt-like mesh 18 rubs the surface of the site in the mouth M, the mesh 103 causes the frictional force in the surface direction of the belt-like mesh 18 to be biased. Even when they occur, it is unlikely that there will be variations in the spacing between adjacent warp yarns 102v and variations in the spacing between the weft yarns 102h.

  That is, when the friction between a part of the mesh 103a and the site in the oral cavity M is large, a large force in the surface direction of the strip mesh 18 is applied to the part of the mesh 103a. Even in this case, since the warp yarns 102v (i), 102v (ii) and the weft yarns 102h (i), 102h (ii) are fixed at the respective heat welding points 108a, 108b, 108c, 108d, only the specific mesh 103a is used. However, it does not spread farther than the other mesh 103.

  For this reason, in this modification, even when there is a difference in the magnitude of friction generated between the band-shaped mesh 18 and the site in the oral cavity M, the variation in the size of each mesh 103 is constant. By restraining within the range, it becomes easy to keep the degree of the cleaning effect of the dirt S of the entire belt-shaped mesh 18 uniform.

  In this modification, the warp yarns 102v and the weft yarns 102h are thermally welded to each other in the sheet thickness direction T of the belt-like mesh 18, so that the warp yarns 102v or the weft yarns 102h are in a position that is biased by one use. Less likely to slip. For this reason, the warp yarn 102v and the weft yarn 102h are easily kept at the first position even in the second and subsequent uses, and the number of possible uses before disposal becomes easy.

  The warp yarn 102v or part of the weft yarn 102h, or part of the warp yarn 102v and part of the weft yarn 102h in this example may include not only a monofilament but also a multifilament obtained by twisting a plurality of single fibers. Good. However, when some of the warp yarns 102v and the weft yarns 102h are multifilaments, they are merely entangled with the weft yarns 102h or the warp yarns 102v that intersect with them, and are not thermally welded with the weft yarns 102h or the warp yarns 102v that intersect them.

  In this way, when the multifilament having a high density of fibers is included in a part of the warp yarn 102v or the weft yarn 102h, the user rubs the site in the oral cavity M in the direction intersecting with the multifilament by the belt-shaped mesh 18. The dirt S can be scraped off more efficiently.

  Incidentally, the belt-like mesh 18 is wound and accommodated in the case 10 shown in the first embodiment in the state of the mesh tape MT continuous in the longitudinal direction. FIG. 9 shows a state where the mesh tape MT is wound around the winding core 10b. Other configurations related to the case 10 are the same as those in the first embodiment.

  The mesh tape MT can be sandwiched between the main body 12 and the movable portion 13 when the mesh tape MT hangs down straight. After being sandwiched, the mesh tape MT is separated by a cutter or the like, leaving a portion stretched between the arm portions 14, 15, 16, and 17 and a portion left in an extra length leftward and rightward. . As a result of the separation, a single piece having such a length as to be stretched between the left and right arm portions 4 and 6 and the right and right arm portions 5 and 7 and the length of the remaining portion is provided. A strip mesh 18 is formed.

  The mesh tape MT can be obtained by slitting a mesh roll obtained by winding a wide mesh sheet into a roll shape so as to have the width of one mesh tape MT. Alternatively, the mesh tape MT may be woven and wound by a weaving process in a narrow state from the beginning.

  11 and 12 illustrate a third embodiment of the present invention. In FIG. 11, reference numeral 21 denotes a floss holder. The floss holder 21 is pivotally attached to the main body 22 and the main body 22, and is a movable member that can freely rotate around the rotation axis Cr in the width direction located at the tip of the main body 22. 23.

  In the floss holder 21, the movable member 23 is disposed on the upper side U of the main body 22, and rotates around the rotation axis Cr as shown in FIGS. 11 and 12. At this time, the movable member 23 rotates so as to be displaced to the near side DB that is the side approaching the main body 22 and the far side UT that is the side away from the main body 22. Other configurations are the same as those in the first embodiment.

  The user of the floss holder 21 supports the floss holder 21 with one hand H1. At this time, the user, for example, holds the main body 22 with four fingers composed of the index finger F2, the middle finger F3, the ring finger F4, and the little finger F5, and rotates the movable member 23 with the thumb F1 so as to pull it toward the near side DB. And it can be operated by rotating in the opposite direction so as to push the far side UT.

  The main body 22 is substantially rectangular in a front view and is Y-shaped in a plan view, and a pair of main body arm portions 24 and 25 that branch from the handle 22a, which is the base portion, into a fork direction T. Have. The handle 22a extends linearly from the base of the main body arm portions 24, 25 to the base end 22b of the main body 22, and is gripped by the user's fingers F2, F3, F4, F5.

  The movable member 23 is Y-shaped in a plan view, and integrally includes a pair of movable arm portions 26 and 27 that are bifurcated from the movable member base portion 23a, which is the base portion thereof, in a front end direction T. The movable member base 23a connects the left movable arm 26 and the right movable arm 27 in the width direction and is operated by the user's thumb F1.

  In a state in which the movable member 23 is closed with respect to the main body 22, the left movable arm portion 26 overlaps the upper side U of the left main body arm portion 24 and the right movable arm portion 27 faces the upper side U of the right movable arm portion 25 in a plan view. The movable member base 23a overlaps with a part of the upper side U of the handle 22a. Thereby, the Y-shape of the movable member 23 and a part of the Y-shape of the main body 22 overlap in the vertical direction of the floss holder 21.

  The movable member 23 is located between the main body 22 and the arm parts 24, 25, 26, 27 including the left main body arm part 24, the right main body arm part 25, the left movable arm part 26, and the right movable arm part 27 in plan view. A dental floss 28 arranged so as to intersect is sandwiched. A combination of the floss holder 21 and the dental floss 28 in the sandwiched state is referred to as a floss holder 29 with a dental floss.

  The user switches the floss holder 21 from the released state to the sandwiched state by, for example, hooking the thumb F1 on the movable member 23 in the released state and rotating the movable member 23 so as to pull it toward the near side DB. Further, the floss holder 21 is switched from the sandwiched state to the released state by rotating the movable member 23 in the sandwiched state so that the movable member 23 is pushed to the far side UT by the thumb F1.

  In the bottom view similar to FIG. 3, the Y-shape of the movable member 23 is such that the movable arm portion length Lb, which is the distance from the root to the tip of each of the left and right movable arm portions 26, 27, is the root of the movable member base portion 23a. It is a shape longer than the base part length La which is the distance from the base end 23b. Therefore, the movable member base 23a is shorter than the left and right movable arm portions 26 and 27.

  Thus, since the base length La is short and the position of the base end 23b is close to the rotation axis Cr, the user can easily hold the handle 22a with the index finger F2, the middle finger F3, the ring finger F4, and the little finger F5, for example, and easily F1 can be hooked to the base end 23b of the movable member 23 in the released state, and the movable member 23 can be easily rotated by the thumb F1.

  Each arm part 24, 25, 26, 27 has locking surfaces 24c, 25c that each main body arm part 24, 25 faces upward U. In addition, each movable arm portion 26, 27 has a locking surface 26c inclined so that the far side UT contacts the locking surfaces 24c, 25c of each main body arm portion in a state where the opening angle θ1 is smaller than 90 degrees. , 27c.

  That is, when the movable member 23 is rotated so as to open with respect to the main body 22 in order to switch from the clamped state to the released state, when the opening angle θ1 increases and approaches 90 degrees, the main body arm portions 24 and 25 are locked. Since the surfaces 24c and 25c are arranged on the rotation tracks of the locking surfaces 26c and 27c of the movable arm portions 26 and 27, the opposing locking surfaces 24c, 26c, 25c and 27c come into contact with each other, and the opening angle They are mutually regulated so that θ1 does not exceed 90 degrees.

  The contact angle between the locking surfaces 24c, 26c, 25c, and 27c is such that the opening angle θ1 is suppressed to less than 90 degrees, so that the movable member 23 does not rotate around the far side UT. That is, the base end 23b does not move away from the thumb F1, the thumb F1 can be hooked on the movable member 23 in the released state, and the movable member 23 can be rotated by the thumb F1.

  With the above configuration, the user can easily bring the floss holder 21 from the released state to the held state with one hand H1 without using the other hand H2 (not shown), and easily change from the held state to the released state. can do.

  In addition, since the user can operate the movable member 23 with the thumb F1 of the hand H1 on the side holding the main body 22, for example, compared with the case where the movable member 23 is rotated by the index finger F2 or the middle finger F3 of the same hand H1. The movable member 23 can be rotated while the index finger F2 and the middle finger F3 are used to hold the main body 22. Thereby, it is possible to easily operate the movable member 23 with the floss holder 21 supported in a well-balanced manner.

  In addition, the user can easily release the dental floss 28 from the floss holder 29 with dental floss with one hand H1, and the floss holder 21 after the floss holder 29 with dental floss has released the dental floss 28. Thus, the dental floss 28 can be easily held again.

  FIG. 13 illustrates a fourth embodiment of the present invention. In FIG. 13, reference numeral 31 denotes a mesh holder. The mesh holder 31 is pivotally attached to the main body 32 and the main body 32, and a movable member that can freely rotate around the rotation axis Cr in the width direction located at the tip of the main body 32. 33. The mesh holder 31 has a movable member 33 disposed on the upper side U of the main body 32 and rotates around the rotation axis Cr. At this time, the movable member 33 rotates so as to be displaced to the near side DB that is closer to the main body 32 and the far side UT that is farther from the main body 32.

  The movable member 33 is located between the main body 32 and the arm portions 34, 35, 36, 37 including the left main body arm portion 34, the right main body arm portion 35, the left movable arm portion 36, and the right movable arm portion 37 in plan view. A belt-like mesh 38 arranged so that the longitudinal directions intersect is sandwiched. A combination of the mesh holder 31 and the belt-shaped mesh 38 in the sandwiched state is referred to as a mesh holder 39 with a belt-shaped mesh.

  In the belt-like mesh 38, the left clamping margin 38 b is sandwiched between the mesh sandwiching step 34 a of the left main body arm 34 and the mesh sandwiching step 36 a of the left movable arm 36. Other configurations are the same as those of the second and third embodiments.

  As shown in FIG. 13, the left main body arm 34 and the left movable arm 36 have a mesh sandwiching step 34a recessed downward D and a mesh sandwiched upward U, respectively, closer to the base end 32b than the rotational axis Cr. You may have the step part 36a so that it may mutually face. Moreover, the right main body arm part 35 and the right movable arm part 37 (not shown) may similarly have the mesh holding step part 35a and the mesh holding step part 37a facing each other. The right clamping margin 38b (not shown) is clamped by the mesh clamping step 35a of the right main body arm 35 and the mesh clamping step 37a of the right movable arm 37.

  14 to 26 illustrate a fifth embodiment of the present invention. In FIG. 14, reference numeral 41 denotes a floss holder. The floss holder 41 includes a main body 42 and a movable member 43 that is pivotally attached to the main body 42 and can freely rotate around a rotation axis Cr in the width direction. The main body 42 and the movable member 43 are each made of acrylonitrile / styrene copolymer (AS), acrylonitrile / butadiene / styrene copolymer (ABS), high impact polystyrene (HIPS), polypropylene (PP), polyethylene terephthalate (PET), It is a molded article of a thermoplastic resin such as polyacetal (POM) which is an engineering plastic. The movable member 43 is disposed on the upper side U of the main body 42.

  As shown in FIGS. 14 and 15A and 15B, the main body 42 is a pair of main body arm portions that bifurcate in a front end direction T from a handle 42a that is a base portion of the Y-shaped main body 42 in plan view. 44 and 45 are integrated. The front ends 44d and 45d of the left main body arm portion 44 and the right main body arm portion 45 are located on the opposite side of the handle 42a with respect to the rotation axis Cr. That is, the main body arm portions 44 and 45 have main body side floss sandwiching portions 44e and 45e extending from the distal ends 44d and 45d to the rotation axis Cr, and main body side flange portions 44f and 45f extending from the rotation axis Cr to the handle 42a. . The floss holder 41 is symmetrical.

  The main body 42 has a substantially N-shape when viewed from the front, curves upward U at the main body side flanges 44f and 45f, and curves downward D at the handle 42a.

  The movable member 43 integrally includes a pair of movable arm portions 46 and 47 that are bifurcated from the movable member base portion 43a, which is a Y-shaped base portion, in the front end direction T in plan view. The respective distal ends 46d and 47d of the left movable arm portion 46 and the right movable arm portion 47 are located on the opposite side of the movable member base portion 43a with respect to the rotation axis Cr. That is, each of the movable arm portions 46, 47 includes a movable floss sandwiching portion 46e, 47e extending from the tip 46d, 47d to the rotation axis Cr, and a movable side flange portion 46f, 47f extending from the rotation axis Cr to the movable member base portion 43a. Have The main body side floss holding parts 44e and 45e are also called first cleaning material holding parts, and the movable side floss holding parts 46e and 47e are also called second cleaning material holding parts.

  Since the movable member base 43a is shorter than the handle 42a in the longitudinal direction and is disposed on the upper side U of the handle 42a, the main body 42 and the movable member 43 intersect each other at the rotation axis Cr in front view. The portions 46f and 47f are located on the upper side U of the main body side flanges 44f and 45f, while the movable side floss holding portions 46e and 47e are located on the lower side D of the main body side floss holding portions 44e and 45e. . Thus, the movable member 43 can overlap with a part of the distal end side T of the main body 42. When the movable member 43 is pushed down, the movable side floss holding portions 46e and 47e are lifted. Conversely, when the movable member 43 is flipped up, the movable side floss holding portions 46e and 47e are lowered. Thus, for example, the dental floss 48 that is previously drawn out from the case 50 and exposed at the tip side T from the rotation axis Cr can be easily picked up by the floss holder 41.

  The movable member 43 bends upward U following a part of the main body 42 as a whole because the movable side flanges 46f, 47f bend upward U following the main body side flanges 44f, 45f in a front view. .

  In the plan view shown in FIG. 15C, the movable member 43 has a movable arm portion length Lb which is a distance from the roots of the left and right movable arm portions 46 and 47 to the distal ends 46d and 47d of the movable member base portion 43a. It is longer than the base length La, which is the distance from the base to the base end 43b. Therefore, the movable member base 43 is shorter in length than the left and right movable arm portions 46 and 47.

  14 to 16 and 20 (a) show the holding state of the floss holder 41, while FIGS. 17 to 19, 20 (b), 21 and 22 show the released state of the floss holder 41. Show. The movable member 43 is displaced around the rotation axis Cr to the near side DB that is closer to the main body 42 as shown in FIGS. 20 and 22B and to the far side UT that is the side farther from the main body 42. Rotate to 14, 17, 20, and 22 (b), the back view of the floss holder 41 is omitted because the back view is symmetrical with the front view.

  As shown in FIGS. 17, 20 (b) and 21 (a), the main body side floss holding portions 44e and 45e are main body side tooth portions 44t facing the counterclockwise UC when viewed from the front centering on the rotation axis Cr. , 45t. The main body side teeth 44t and 45t are triangular prisms whose longitudinal direction is the direction from the rotation axis Cr toward the tips 44d and 45d, the bottom in the transverse section faces the front view clockwise CL, and the apex is the ridge 44s. , 45s.

  The ridgelines 44s and 45s of the main body side tooth portions 44t and 45t form the clamping edges of the main body side floss clamping portions 44e and 45e.

  As shown in FIGS. 20 (a) and 21 (a), the main body side floss holding parts 44e and 45e are formed so as to be thinner by one step in the clockwise direction CL near the front ends 44d and 45d. 44es, 45es.

  Further, the movable side floss holding portions 46e and 47e have movable side teeth portions 46t and 47t facing the clockwise CL as viewed from the front as shown in FIGS. 17, 20A, 20B, and 21B. . The movable side teeth 46t, 47t are triangular prisms whose longitudinal direction is the direction from the rotation axis Cr toward the tips 46d, 47d, the base in the cross section faces the counterclockwise UC when viewed from the front, and the apex is the ridgeline. It has a triangular prism shape forming 46s and 47s.

  The ridge lines 46s and 47s of the movable side tooth portions 46t and 47t form the clamping edges of the movable side floss clamping portions 46e and 47e. The movable side teeth 46t and 47t including the ridge lines 46s and 47s sandwich the dental floss 48 from both sides toward the center of the transverse section together with the main body side teeth 44t and 45t including the ridge lines 44s and 45s.

  As shown in FIGS. 17, 20 (a), (b) and FIG. 21 (b), the movable side floss sandwiching portions 46 e and 47 e become thicker in the clockwise direction CL near the front ends 46 d and 47 d. It has jaws 46eh and 47eh to be formed.

  The main body side floss holding portions 44e and 45e mesh with the movable side floss holding portions 46e and 47e of the movable arm portions 46 and 47 facing each other in the holding state.

  At this time, for example, the movable floss holding portion 46e of the left movable arm portion 46 is located between the leftmost movable side tooth portion 46t1 of the movable side tooth portion 46t and the second movable side tooth portion 46t2 facing rightward R. In addition, the leftmost L body side tooth part 44t1 of the body side tooth parts 44t is sandwiched in the width direction of the floss holder 41, and the other body side teeth are similarly placed between the movable side tooth parts 46t2, 46t3 and 46t4. When the portions 44t2 and 44t3 are sandwiched, the main body side floss sandwiching portion 44e of the left main body arm portion 44 is engaged.

  Similarly, the movable side floss sandwiching portion 47e of the right movable arm portion 47 is engaged with the main body side floss sandwiching portion 45e of the right main body arm portion 45 by sandwiching the main body side tooth portion 45t between the movable side tooth portions 47t.

  The dental floss 48 is sandwiched between the opposing floss sandwiching portions 44e, 45e, 46e, 47e so as to be orthogonal to the ridgelines 44s, 45s, 46s, 47s of the tooth portions 44t, 45t, 46t, 47t in plan view. Is done. As a result, the dental floss 48 is sandwiched so as to follow the tooth profiles of the respective tooth portions 44t, 45t, 46t, 47t, so that it is displaced in the length direction or the cross-sectional direction due to friction between these tooth profiles. Or there is little possibility that it will pull out from the floss holder 41. In this way, the floss holder 49 with dental floss is obtained by sandwiching the dental floss 48 with the floss holder 41.

  21A and 21B show the case where there are three main body side teeth 44t and four movable side teeth 46t, the width on the tip side T of the floss holder 11 is shown. Can be inserted into the human mouth M, and the dental floss 48 is less likely to be pulled out in the length direction, each body side tooth portion 44t, 45t is one or more and within six. And the number of movable side teeth 46t, 47t may be 2 or more and 7 or less. Moreover, it is not restricted to the case where the number of movable side tooth parts 46t and 47t is larger than the number of main body side tooth parts 44t and 45t, and these are the same number or the main body side rather than the number of movable side tooth parts 46t and 47t. The number of the tooth portions 44t and 45t may be larger.

  Further, as shown in FIG. 20A, the jaw portions 46eh and 47eh of the movable side floss sandwiching portions 46e and 47e facing each other are combined with the jaw receiving portions 44es and 45es of the main body side floss sandwiching portions 44e and 45e. . Therefore, in the clamping state, the jaw portions 46eh and 47eh are positioned so as to cover the tooth portions 44t, 45t, 46t, and 47t from the distal ends 44d, 45d, 46d, and 47d side.

  Thus, the dental floss 48 in the clamping state is less likely to be pulled out in the length direction by being clamped so as to follow the tooth profile of each tooth portion 44t, 45t, 46t, 47t as described above. In addition, even if sliding occurs in the cross-sectional direction of the dental floss 48 toward the tips 44d, 45d, 46d, and 47d, the tips 44d, 45d, 46d, and 47d are blocked by the jaw portions 46eh and 47eh. There is little risk of pulling out from the side.

  Further, when the floss holder 41 is operated so as to be switched from the released state to the pinched state, for example, when the dental floss 48 fed out from the case 50 is pinched, the jaws 46eh and 47eh projecting clockwise CL when viewed from the front. Can hook dental floss 48.

  Thereby, the floss holder 41 can easily clamp the dental floss 48. Further, the floss holder 49 with dental floss can easily hold the dental floss 48 again from the state in which the dental floss 48 is released.

  As shown in FIGS. 20 (a) and 20 (b), the main body side flange 44f is a substantially square having a top surface that protrudes counterclockwise UC when viewed from the front centered on the rotation axis Cr and faces the counterclockwise UC. It has a projection-like fitting projection 44fp. Further, the movable side flange 46f has a fitting recess 46fr having a substantially quadrangular thrust platform that opens toward the clockwise CL and has a bottom surface facing the clockwise CL. The opposite main body side flange 45f and movable side flange 47f also have similar fitting protrusions 45fp and fitting recesses 47fr, respectively.

  Each fitting recess 46fr, 47fr is positioned on the rotation path of each fitting projection 44fp, 45fp with the rotation axis Cr as the center, and each fitting projection 44fp, 45fp is loosely fitted inside. It is formed slightly larger than the size of the fitting convex portions 44fp, 45fp. Therefore, in the clamped state, the fitting convex portions 44fp and 45fp are loosely fitted into the fitting concave portions 46fr and 47fr of the opposed movable side flange portions 46f and 47f.

  As a result, when the movable member 43 rotates and switches from the released state to the sandwiched state, the fitting convex portions 44fp and 45fp guide the fitting concave portions 46fr and 47fr, and the movable floss sandwiching portions 46e and 46e, 47e can be guided to a position where the main body side floss holding portions 44e and 45e are engaged with each other. Therefore, each tooth part 44t, 45t, 46t, 47t can be accommodated in a predetermined position without being displaced in the width direction of the floss holder 41.

  Thus, the floss holder 41 can easily hold the dental floss 48.

  If the fitting recess can guide the fitting projection to guide the movable side floss holding portions 46e and 47e to the positions where the main body side floss holding portions 44e and 45e are engaged with each other, the reverse of the above example In addition, the main body side flanges 44f and 45f have fitting recesses, and the movable side flanges 46f and 47f have fitting protrusions. A structure in which the fitting convex portions of the flange portions 46f and 47f are loosely fitted may be used.

  As shown in FIG. 20 (a), the left side L-side movable floss holding portion 46e is bent toward the main body side floss holding portion 44e with respect to a straight line extending radially from the rotation axis Cr in the bent portion 46en. Formed as follows. The right side movable floss sandwiching portion 47e on the right side R is also formed to be bent in the same manner at a bent portion 47en (not shown).

  Compared with the case where these movable side floss clamping portions 46e and 47e are not bent, the ridge lines 46s and 47s of the movable side tooth portions 46t and 47t are replaced with the ridge lines 44s and 44t of the main body side tooth portions 44t and 45t, respectively. It is formed to be bent by an angle that can be directed in a direction parallel to 45 s. Accordingly, since the ridge lines 44s and 45s of the main body side tooth portions 44t and 45t and the ridge lines 46s and 47s of the movable side tooth portions 46t and 47t are parallel to each other in the sandwiched state, the ridge lines 44s, 45s, 46s and 47s are included. The tooth portions 44t, 45t, 46t, and 47t are formed so that the dental floss 48 is opposed to the center of the transverse section by 180 degrees in two directions and in a direction substantially orthogonal to the respective ridgelines 44s, 45s, 46s, and 47s. Can be pinched.

  Therefore, even if the dental floss 48 is sandwiched at any position in the direction of the ridgelines 44s to 47s of the tooth portions 44t, 45t, 46t, and 47t, a uniform frictional force can be applied to the dental floss 48. As a result, even in the clamped state, for example, it is difficult for the dental floss 48 to slide in the cross-sectional direction toward the distal ends 44d, 45d, 46d, 47d or toward the rotation axis Cr. Therefore, the dental floss 48 does not fall out of the floss holder 41.

  In addition, when the movable side floss holding portions 46e and 47e approach the main body side floss holding portions 44e and 45e from the released state to the holding state, the movable side tooth portions 46t and 47t are not formed so as to be bent. Since the angle formed between each ridge line 46s, 47s and each ridge line 44s, 45s of the body side tooth portions 44t, 45t is small, the dental floss 48 is relatively easily interposed between the floss sandwiching portions 44e, 45e, 46e, 47e. It is pinched.

  As described above, the floss holder 41 can easily hold the dental floss 48.

  If the ridge lines 44s and 45s of the main body side teeth 44t and 45t and the ridge lines 46s and 47s of the movable side teeth 46t and 47t can be made parallel in the clamping state, the movable side floss clamping parts 46e and 47e Instead, the main body side floss holding portions 44e and 45e may be bent toward the movable side floss holding portions 46e and 47e. Further, both the main body side floss holding portions 44e and 45e and the movable side floss holding portions 46e and 47e may be bent toward the respective floss holding portions 46e, 47e, 44e and 45e.

  The floss holder 41 has engagement means 42c and 43c for detachably engaging the main body 42 and the movable member 43 with each other.

  The engaging means 42c and 43c are constituted by a locking projection 42c and a locking edge 43c. The main body 42 has a locking projection 42c, and the locking projection 42c has a substantially rectangular shape in a plan view passing through the bases of the main body arm portions 44 and 45 in the vertical direction as shown in FIGS. After projecting from the inner wall on the distal end side T of the main body side through hole 42h in the base end direction B, it is bent in an L shape when viewed from the front and protrudes upward U from the main body 42. Further, the locking protrusion 42c has a locking claw 42d that is bent in a hook shape and protrudes in the base end direction B from the upper U end.

  Further, the movable member 43 has a locking edge 43c, and the locking edge 43c is located on the base end 43b side in the movable side through hole 43h that penetrates the movable member 43 in the thickness direction at the base of each movable arm portion 46, 47. The inner wall and the upper U surface of the movable member base 43a constitute an edge. The locking projection 42c is inserted from the lower side D of the movable member 43 into the movable through hole 43h when the movable member 43 is closed and switched from the released state to the clamped state, and the latching claw 42d is engaged in the clamped state. The movable member 43 is locked downward D by being caught by the stop edge 43c.

  Thereby, the movable member 43 is engaged with the main body 42 in the clamping state after rotating around the rotation axis Cr so as to be displaced to the near side DB. The user can easily clean the teeth with one hand while holding the floss holder 41 in a sandwiched state.

  Further, when the movable member 43 is opened and switched from the sandwiched state to the released state, the user removes the locking claw 42 d from the locking edge 43 c and releases the movable member 43 from the locked state with the main body 42. Then, the user rotates the movable member 43 to the far side UT. The user can prepare for the next use by putting the floss holder 41 in the released state.

  The left main body arm portion 44 has a columnar support shaft 44b having a rotation axis Cr as a center line as shown in FIG. The left main body arm portion 44 has a left main body side recessed portion 44k that is recessed in the right direction R to approximately ½ of the width direction of the left main body arm portion 44 around the rotation axis Cr. The support shaft 44b forms a cylinder projecting leftward L from the surface of the left main body recess bottom wall 44g facing leftward in the left main body side recess 44k.

  The left movable arm portion 46 has a cylindrical shaft hole 46b having a rotation axis Cr as a center line as shown in FIG. 23B and penetrating the left movable arm portion 46 in the width direction. The left movable arm portion 46 has a left movable side recessed portion 46k that is recessed in the leftward direction L to approximately ½ of the width direction of the left movable arm portion 46 around the rotation axis Cr. The shaft hole 46b is drilled leftward from the surface of the left movable recess bottom wall 46g facing right in the left movable side recess 46k.

  The inner diameter of the shaft hole 46b is slightly larger than the outer diameter of the support shaft 44b.

  The left main body arm portion 44 and the left movable arm portion 46 are configured such that the left main body side recess portion 44k and the left movable side recess portion 46k are arranged so that the left main body recess bottom wall 44g and the left movable recess bottom wall 46g face each other. Combine by mating. At this time, the support shaft 44b is loosely fitted into the shaft hole 46b so that the outer periphery of the support shaft 44b faces the inner periphery of the shaft hole 46b.

  As for the right main body arm portion 45 and the right movable arm portion 47, the right main body arm portion 45 and the right movable arm portion 47 are combined in the same manner as the left main body arm portion 44 and the left movable arm portion 46 described above. Further, the support shaft 45b is loosely fitted into the shaft hole 47b so that the inner diameter of the shaft hole 47b is slightly larger than the outer diameter of the support shaft 45b and the outer periphery of the support shaft 45b faces the inner periphery of the shaft hole 47b.

  Thus, the main body arm portions 44 and 45 pivotally support the movable arm portions 46 and 47 that are opposed to each other about the rotation axis Cr. When the movable arm portions 46, 47 are rotated to switch between the sandwiched state and the released state, the arm portions 44, 45, 46, 47 are prevented from interfering with each other. 45k and each movable side recessed part 46k, 47k have sufficient volume.

  When the main body 42 and the movable member 43 are assembled, for example, when both the main body 42 and the movable member 43 are made of polypropylene (PP), the main body arm portions 44 and 45 are elastically deformed so as to bend inward, and the movable members 43 are movable. By elastically deforming the arm portions 46 and 47 so as to bend outward, the main body side recesses 44k and 45k and the movable side recesses 46k and 47k are easily fitted together. The shaft holes 46b and 47b can be easily fitted to the support shafts 44b and 45b. With these structures, the main body 42 and the movable member 43 can be easily assembled.

  In the clamping state shown in FIG. 14, the main body 42 restricts the movable portion 43 from rotating further to the near side DB by the movable member base portion 43a coming into contact with the handle 42a.

  On the other hand, in the released state shown in FIG. 20B, the main body 42 has inclined surfaces 46j and 47j that are continuous from the bent portions 46en and 47en of the movable arm portions 46 and 47 to the base end 43b side in FIG. The movable member 43 is regulated so as not to be rotated further to the far side UT by abutting on the inner wall 44j, 45j facing the front end of the main body recess, which is the inner wall of the front end T of each main body side recess 44k, 45k. .

  As a result, as shown in FIG. 22B, the opening angle θ1 formed by the straight line connecting the base end 43b and the rotation axis Cr and the longitudinal direction of the main body 42 of the movable member 43 is limited to a maximum of 80 degrees. That is, the opening angle θ1 is suppressed to less than 90 degrees. As a result, the user can easily turn the movable member 43 to the front side DB by hooking, for example, the thumb F1 of the hand H1 on the side supporting the floss holder 41 to the base end 43b, And it can be rotated so as to push the far side UT.

  24A and 24B show photographs taken from obliquely above the floss holder 41 with the movable member 43 closed and opened, respectively. FIG. 25 shows a photograph of the floss holder 49 with dental floss taken from the upper side U. Other configurations are common to the third embodiment.

  By the way, the dental floss 48 is wound and accommodated in a case 50 shown in FIG. 26A, for example, and is exposed and exposed to the outside of the case from the supply port 50c by the user. The case 50 includes a cutter 50d, and is longer than the width from the left arm portion 44, 46 of the floss holder 41 to the right arm portion 45, 47 between the feeding port 50c and the cutter 50d. The length of dental floss 48 can be stretched linearly.

  As described above, each of the arm portions 44, 45, 46, and 47 has floss sandwiching portions 44e, 45e, 46e, and 47e from the distal ends 44d, 45d, 46d, and 47d to the rotation axis Cr. And the dental floss 48 is clamped between the main body side floss clamping parts 44e, 45e and the movable side floss clamping parts 46e, 47e as shown in FIG. 26 (b).

  At this time, as described above, the user can easily hold the floss holder 41 from the released state with one hand H1 without using the other hand H2. The floss holder 41 in the released state is supported from the distal end 44d, 45d, 46d, 47d side of each arm portion 44, 45, 46, 47 while supporting the case 50 by the other hand H2 and supporting the case 50 by the other hand H2. The dental floss 48 can be easily grasped by approaching the floss 48.

  In addition, at this time, as described above, the jaws 46eh and 47eh protruding in the clockwise direction CL can easily hook the dental floss 48 as described above.

  For example, when the dental floss 48 is stretched linearly between the feeding port 50c and the cutter 50d as shown by the case 50 in FIG. 26 (a), the user firstly has one hand H1. The linear dental floss 48 is clamped by the arm portions 44, 45, 46, 47 of the floss holder 41 supported by, and the case 50 is supported by the other hand H2. Second, while holding the floss holder 41 away from the case 50, the dental floss 48 to be used next is fed out from the feeding port 50c.

  Thirdly, after the new dental floss 48 that has been fed is stretched between the feeding port 50c and the cutter 50d, tension is applied to the dental floss 48 by the floss holder 41, and the portion of the dental floss 48 applied to the cutter 50d is applied. Can be cut. Thereby, the dental floss 48 for the next use is stretched in a straight line between the feeding port 50c and the cutter 50d.

  In this way, the user can easily draw out and hold the dental floss 48 as necessary by the floss holder 41 as shown in FIG. During this time, the user can perform these operations with the hands H1 and H2 while supporting the floss holder 41 and the case 50. In addition, the floss holder 41 does not need to be a translucent body as shown in FIGS. 24 to 26, and may be colored white or other colors, or may be a transparent body.

  The user engages the movable member 43 with the main body 42 with the floss holder 41 sandwiching the dental floss 48, so that the floss holder 49 with dental floss that is a combination of the floss holder 41 and the dental floss 48 in the sandwiched state is used. Get. After the movable member 43 is once engaged with the main body 42, the engaged state is not released unless the engaging claw 42d is detached from the engaging edge 43c, so that the user holds the floss holder 49 with dental floss in a sandwiched state. Teeth can be easily cleaned.

  In addition, after the user uses the dental floss holder 49, the user removes the locking claw 42d from the locking edge 43c, releases the movable member 43 from the engaged state with the main body 42, and puts the floss holder 41 in the released state. Can prepare for the next use.

  Further, each arm portion 44, 45, 46, 47 is curved upward U at each flange portion 44f, 45f, 46f, 47f. Therefore, the user can bring the floss holding portions 44a, 45a, 46a, 47a closer to the dental floss 48 before clamping by simply tilting the floss holder 41 so that the tip side T is displaced downward D, and the floss holder The dental floss 48 can be easily clamped by 41.

  In addition, the user can make a dental treatment between the first back tooth T1 (not shown) and the second back tooth T2 adjacent to the first back tooth T1, for example, by bending the flanges 44f, 45f, 46f, 47f. A floss holder 49 with a dental floss can be used in the deep part of the mouth M so that the floss 48 is inserted.

  Further, since the user is restricted so that the opening angle θ1 of the movable member 43 does not exceed 90 degrees, the base end 43b of the movable member 43 is far from the user's fingers F1 to F5 including the thumb F1. The movable member 43 can be easily rotated so as to be displaced to the near side DB and the far side UT without leaving.

  At this time, since the movable side flanges 46f and 47f are curved upward U, for example, the thumb F1 can easily reach the base end 43b of the movable member 43, and the user can easily operate. The same applies when operating with fingers F2 to F5 other than the thumb F1.

  In order to cut the dental floss 48, the user may use a tool such as a scissor supported by the other hand H2 instead of using the cutter 50d of the case 50. Further, in the state where the case 50 is supported by the other hand H2, the dental floss 48 that has been drawn out from the case 50 in advance may be sandwiched by the floss holder 41 supported by the one hand H1. Further, the dental floss 48 cut in advance to a predetermined length may be held by the floss holder 41 supported by the one hand H1 while being supported by the other hand H2.

  The configuration in the present embodiment is not limited to these configurations, and various modifications are possible. For example, for each floss clamping part 44e, 45e, 46e, 47e, the cross-sectional shape of each tooth part 44t, 45t, 46t, 47t may not be triangular, and the dental floss 48 may be clamped so as to follow the tooth profile. For example, other shapes such as a trapezoid or a rectangle may be used. When the cross section is trapezoidal or rectangular, the top surfaces of the tooth portions 44t, 45t, 46t, and 47t form the clamping edges of the floss clamping portions 44e, 45e, 46e, and 47e.

  The dental floss 48 is not only sandwiched so as to be orthogonal to the ridge lines 44s, 45s, 46s, 47s of the respective tooth portions 44t, 45t, 46t, 47t in plan view, but shifted in the length direction or the cross-sectional direction, or If the friction to the extent that it does not pull out occurs between the tooth shapes of the tooth portions 44t, 45t, 46t, and 47t, they may be sandwiched at an angle slightly inclined from the orthogonal direction.

  Further, each tooth portion 44t, 45t, 46t, 47t may have a notch in a part of the ridge lines 44s, 45s, 46s, 47s in order to guide the dental floss 48 to a predetermined position when sandwiched. .

  Further, the movable side floss holding portions 46e and 47e have jaw portions 46eh and 47eh, and the main body side floss holding portions 44e and 45e do not have jaw receiving portions 44es and 45es, but tips 44d, 45d, 46d, If the dental floss 48 is slid in the direction of its cross section toward 47d, if it is blocked by the jaw, the main body side floss holding portions 44e, 45e have the jaw portion and the movable side floss holding The parts 46e and 47e may have a chin rest.

  The engaging means may be constituted by a locking projection on the movable member 43 side and a locking edge on the main body 42 side. Further, the locking protrusion may protrude in the distal direction T, and the locking claw may protrude not only in the proximal direction B but also in the distal direction T.

  Regarding the assembly of the main body 42 and the movable member 43, the left main body arm portion 44 may have a support shaft that protrudes in the right direction R, and the right main body arm portion 45 may have a support shaft that protrudes in the left direction L. At this time, the main body arm portions 44 and 45 are elastically deformed so as to bend outward, and the movable arm portions 46 and 47 are elastically deformed so as to be bent outward.

  Moreover, the movable arm parts 46 and 47 may have a support shaft, and the main body arm parts 44 and 45 may have a shaft hole.

  Furthermore, if not only the main body arm portions 44 and 45 and the movable arm portions 46 and 47 are bent but also the main body 42 or the movable member 43 can be elastically deformed, the main body arm portions 44 and 45 and the movable arm portion 46 are provided. , 47 may be formed to bend.

  The rotation of the movable portion 43 is not only restricted by the inclined surfaces 46j and 47j coming into contact with the inner walls 44j and 45j facing the front end of the main body depression, but other portions or in addition to these portions. The portions other than these may be regulated by contacting each other.

  Even if the floss holding portions 44e, 45e, 46e, 47e are not bent, the dental floss 48 is held in a direction orthogonal to the ridgelines 44s, 45s, 46s, 47s of the tooth portions 44t, 45t, 46t, 47t in a front view. In addition, the inner diameters of the shaft holes 46b and 47b are made larger than the outer diameter of the support shafts 44b and 45b, or the shaft holes 46b and 47b are made into an oval shape, or the inner diameter is made larger and an oval shape. You may absorb the thickness of the dental floss 48 by making it into a shape.

  Further, the floss holding portions 44e, 45e, 46e, and 47e may be bent, and the shaft holes 46b and 47b may be formed of these.

  FIG. 27 illustrates a sixth embodiment of the present invention. In FIG. 27, 51 is a mesh holder, and this mesh holder 51 includes a main body 52 and a movable member 53 that is pivotally attached to the main body 52 and can freely rotate around a rotation axis Cr in the width direction. The movable member 53 is disposed on the upper side U that is the front side of the figure of the main body 52.

  The main body 52 integrally includes a pair of main body arm portions 54 and 55 that are bifurcated from the handle 52a, which is the base of the Y-shaped main body 52, in the front end direction T in plan view. The front ends 54d and 55d of the left main body arm portion 54 and the right main body arm portion 55 are located on the opposite side of the handle 52a with respect to the rotation axis Cr. That is, the main body arm portions 54 and 55 have main body side mesh holding portions 54e and 55e extending from the distal ends 54d and 55d to the rotation axis Cr, and main body side flange portions 54f and 55f extending from the rotation axis Cr to the handle 52a. . The mesh holder 51 is symmetrical.

  The main body 52 has a substantially N shape when viewed from the front as in FIG. 14, and is curved upward U at the main body side flanges 54f and 55f and curved downward D at the handle 52a.

  As shown in FIG. 27, the movable member 53 integrally includes a pair of movable arm portions 56 and 57 that are bifurcated from the movable member base portion 53 a that is a Y-shaped base portion in a plan view toward the distal end T.
