JP7072201B2 - Rotation assist mechanism of rotating body - Google Patents

Description

The present invention relates to a rotation assisting mechanism that assists the rotation of a rotating body rotatably provided in a container or the like, and is particularly used for a neck finish of a container and is configured to be rotatable by rotation. Rotation to facilitate the opening of a rotary opening type cap body or a screw cap that can be opened and closed with a spiral structure on the inner peripheral surface that can be opened or closed depending on the direction of rotation. It is about the auxiliary mechanism.

As an example of a rotating body that is rotatably provided in a container or the like, a glue stick that is widely used as stationery can be mentioned. The stick glue comprises a rotating body in which the lower end of the stick glue body is inserted into a cup, the cup is housed in a tubular case, and is arranged so as to be relatively rotatable so as to close one end of the tubular case. The cup is configured to be movable in the axial direction by the rotational operation of the rotating body, and the stick glue main body is configured to freely appear and disappear from the open end of the cylindrical case with the axial movement. This type of glue stick is difficult to use for those who have almost no grip strength because there is no part for hooking fingers or the like.

In addition, containers containing viscous fluid detergents such as shampoos, conditioners and treatments, hair wash agents and liquid detergents, and foods and drinks such as seasonings, favorite beverages and refreshing beverages are used by many users. For example, as a container for a viscous fluid containing a sugar such as jam, a wide-mouthed glass bottle is used for accommodating jam. In many cases, a screw cap made of metal and having a large radius is used to open and close this glass bottle. However, in a glass container for jams equipped with a screw cap mechanism, once used, a screw cap with a large radius is used because highly viscous sugar etc. easily adheres between the container opening and the lid. There was a problem that a strong force was often required to open and close the glass even though it was adopted. In addition, detergent bottles containing viscous fluid detergent such as shampoo are often used in water areas such as bathrooms and washrooms, and are wet when refilling the detergent content. It is often the case with the hands, etc., and the fingers may slip, making it difficult to open the stopper of the bottle.

Patent Document 1 is an invention of a screw cap that prevents the virgin portion from remaining in the bottle mouth portion to prevent unauthorized opening and makes it difficult to break the bridge of the easily broken portion at the time of closing and easy to break at the time of opening, and the virgin cap is known. ing. In this virgin cap, a tubular ring having a vertical slit formed is continuously provided at the opening of the cap body via an easily broken portion and a non-breaking connecting portion to form a concave portion or a convex portion in the vicinity of the cap main body. A moving stopper for the concave portion or the convex portion is provided in the center, and the concave portion or the convex portion and the non-breaking connecting portion are configured to be positioned so as to be sandwiched between both sides of the vertical slit.

In addition, when this virgin cap engages the tubular ring with the bead of the bottle by screwing with the bottle mouth, the force that widens the vertical slit when the cap is closed acts on the stopper directly or via the lateral bridge. The vertical slit does not widen, and the easily broken connecting part that connects the cap body and the tubular ring is not cut. Further, in this virgin cap, when the cap body is rotated in the opening direction, the easily broken connecting portion between the cap body and the tubular ring is broken, but the non-breaking connecting portion is not broken, and the cap body and the tubular shape are formed. It is configured so that the ring and the ring come off the bottle mouth together.

In addition to being disclosed in Patent Document 1, for example, a PET bottle in which a screw cap mechanism is formed in a resin bottle made of polyethylene terephthalate and a resin cap made of polyethylene or polypropylene is screwed is used for beverages. Has been widely adopted in recent years. Most PET bottles are Tamper evidence containers with an integrally molded Tamper Evident Band (cylindrical ring, virgin part) that connects to the bottom of the resin cap with a thin bridge. Is.

The tamper evidence band has a structure that even if the resin cap is rotated in the opening direction, it is restrained by the bottle side and cannot rotate in the opening direction. .. Moreover, since the tamper evidence band can be easily and clearly visually discriminated by the naked eye of the consumer as to whether it is connected or disconnected, the tamper evidence property is ensured. Tamper evidence refers to a function that prevents unauthorized opening or guarantees virginity.

In other words, if the tamper evidence band is connected to the bottom of the resin cap with a bridge, the contents are unopened and the quality is guaranteed, but if the bridge is broken, it is opened and other than the final consumer. If someone has opened the cap, it is clearly stated that considerable consideration should be given to the quality of the contents. Hereinafter, including this type of resin cap, the term "screw cap" will be used in this case.

As described above, the screw cap mechanism constitutes a screw-type openable / closable lid plug at the mouth plug portion, that is, the container opening in a container such as a plastic bottle such as a PET bottle or a glass bottle. This screw cap mechanism includes an engaging receiving portion spirally formed on the outer peripheral surface of the spout portion, a screw cap screwed into the engaging receiving portion, and a screw cap configured to open and close the spout portion. It is composed of more. The screw cap is composed of a body cylinder portion having an engaging portion formed on the inner peripheral surface and a closing portion that closes one end side thereof. Containers equipped with a spout portion of a screw cap mechanism are used in a wide range of containers because of their high airtightness and the ability to open and close repeatedly.

The PET bottle cap standard is not stipulated by international standards such as JIS, ISO, and ASME, but is stipulated by a voluntary standard voluntarily set by the beverage packaging container industry group. This standard does not specify only "screws", but covers the entire shape of the spout. Currently, the standards used in Japan are generally the "Alcoa 1716 standard" and "PCO 1810 standard", which mainly correspond to the diameter of φ28 mm. Both are established and managed by the CMA in the United States.

PET bottles are required to have a high degree of airtightness because they must cope with an increase in internal pressure due to a temperature rise in a container such as a carbonated drink or a gas space in a container. Therefore, a reliable closing force is required for the cap of the container opening of the PET bottle. On the other hand, since the PET bottle cap gives priority to ease of drinking, the outer diameter of the container opening is small in relation to the size of the lips of the drinker, and the outer diameter of the cap is naturally small. As a result, the moment of force becomes disadvantageous, and the torque in the opening direction required for opening the cap becomes considerably large.

In particular, in the case of the first opening of an unopened PET bottle, a rotational torque for breaking the integrated connection portion between the screw cap and the tamper evidence band, that is, the bridge is also required. Due to these causes, children and women, the elderly and the sick, or those with a physical handicap may not be able to open the unopened PET bottle for the first time. There was a problem that it was difficult to open and close after opening.

As a thing corresponding to the problem of such a conventional screw cap mechanism, for example, there is an opening assisting tool as disclosed in Patent Document 2. It is a thick rubber band-like opening aid with a closed curve as a whole and a non-slip formed on the inner peripheral surface. With this opening aid, the outer peripheral surface of the screw cap is surrounded by a part or all of the rubber band-like part and tightened while exerting a non-slip effect, so that the screw is screwed by the thickness of the rubber band-like part. By increasing the radius of gyration of the cap, the force required to open and close the screw cap can be reduced.

Japanese Unexamined Patent Publication No. 2006-182357 Registered Utility Model No. 3048082 WO2009 / 113321 Gazette

However, the rubber band-like opening aid of Patent Document 2 is used by tightening the body cylinder portion of the screw cap from the outer peripheral surface. Therefore, the inner peripheral surface of the screw cap and the engaging portion formed on the inner peripheral surface are strongly tightened to the outer peripheral surface of the container opening and the engaging receiving portion formed on the outer peripheral surface, and the frictional force is enhanced. However, there was a problem that the force required for opening and closing increased. In particular, in the case of a plastic screw cap, the barrel portion of the screw cap is easily deformed in the diameter direction, so that the barrel portion that is strongly tightened and has a reduced diameter significantly increases the frictional force with the container opening. However, there is a problem that the force required to open and close the screw cap becomes large.

As a thing corresponding to the problem of the rubber band-like opening assisting tool of Patent Document 2, for example, a screw cap rotation assisting mechanism as disclosed in Patent Document 3 (hereinafter, "mechanism of Document 3", or simply There was also a "mechanism"). This mechanism has a connecting portion that is attached to the screw cap and one end of which rotates integrally with the screw cap, and a rotation assisting portion that is connected to this connecting portion. It is located close to the screw cap and can be separated from the screw cap during rotation to create a large diameter part that rotates integrally with the screw cap, while the rotational force required for the rotation operation of the screw cap is smaller. It is configured so that it can be.

Since the mechanism of Document 3 is removable, it can be used repeatedly at low cost, and the bottle product and the mechanism of Document 3 are sold separately, for example, in a product form (hereinafter, also referred to as "detachable type"). In this case, the separately sold mechanism may be attached to the screw cap by the final consumer of the bottle product (more accurately, the person who opens the bottle) to assist the rotation (opening and / or closing). It is possible.

Such a "detachable" mechanism is configured so that the connecting portion fitted to the screw cap is elastically deformed to some extent so that it can be easily attached and detached. The reason is that people who need opening assistance have weak hands. In other words, if the "detachable" mechanism needs to be retrofitted as an optional item, even if it is obtained by a person with weak hands, if it cannot be easily attached to the screw cap, it will assist in opening the cap. This is because it is useless. As described above, the mechanism that is easy to attach is often easy to remove.

On the other hand, there is also a desire for the final consumer, who has weak hand power, to save the trouble of attaching the separately sold opening assist mechanism to the screw cap. Therefore, it is conceivable to distribute and sell bottle products attached to screw caps in advance at bottling factories and the like. In that case, after being fitted to the screw cap once (hereinafter, also referred to as "fitted state"), it should be distributed to the final consumer as if it were integrated with the bottle product without removing it. A product form (hereinafter, also referred to as "integrated type") is desired. In the case of such an "integrated type", it is necessary to devise a way to prevent the product from coming out of the "fitted state" during distribution from a bottling factory or the like to the hands of the final consumer. Further, in the opening assist mechanism of Patent Document 3, the other end side of the connecting portion in the lever portion is a free end that can be separated from the body cylinder portion of the screw cap, but these extend from the connecting portion to the free end of the lever portion. Even if the series is configured so that there is no problem in terms of strength, it is possible to make the user feel psychological strength anxiety, and in some cases, it is desirable to devise so as not to give psychological anxiety.

In addition, in each figure, parts having the same function and the like are designated by the same reference numerals to avoid duplication of description. Further, the "screw cap rotation assisting tool (main assisting tool)" shown in FIGS. 1 to 21 and 28 to 34 and the "rotation assisting type cap (main cap)" shown in FIGS. 22 to 27 are shown. Collectively, it is defined as "rotation assist mechanism of rotating body".
[First Embodiment]

FIG. 1 is a diagram illustrating the present auxiliary tool, and is a perspective view showing an unused state. As shown in FIG. 1, the auxiliary tool 100 is provided with an operation portion 30 so as to cover the screw cap 10 with the fitting ring portion 50 and tightly fit the screw cap 10, thereby facilitating the transmission of torque in the opening direction F. It is a thing.

FIG. 2 is a perspective view showing a state in which the auxiliary tool of FIG. 1 is fitted to a screw cap and is not opened. As shown in FIG. 2, knurls 29 are engraved in a vertical stripe shape on the inner peripheral surface of the ring-fitting portion 50. The knurl 29 fits the unevenness of the knurl 19 engraved in a vertical stripe on the outer peripheral surface 18 of the screw cap 10.

As described above, the ring portion 50 and the outer peripheral surface 18 of the screw cap 10 can be tightly fitted because the knurls 19 and 29 of the fitting surfaces coincide with each other, and do not slide in the axial rotation direction in particular. Therefore, it is possible to satisfactorily transmit the rotational torque from the operating portion 30 to the screw cap 10 via the ring fitting portion 50 and the outer peripheral surface 18 of the screw cap 10.

Further, the outer peripheral surface of the ring-fitting portion 50 is a pseudo outer peripheral surface 27 (FIGS. 6, 7, 12 to 17) having the same function as the outer peripheral surface 18, and the operation portion 30 is arranged on the pseudo outer peripheral surface 27. .. The auxiliary tool 100 is planned as a product in which the operation unit 30 is fitted to the screw cap 10 at an earlier stage in a series of processes in which the bottling product is manufactured, distributed, sold, and consumed. Is preferable.

Specifically, in a mass production process such as a bottling (for example, bottling into a PET bottle) factory, an operation unit 30 that is separate from the general screw cap 10 that has not been processed is immediately after the bottling process. It is preferable to plan a product that increases added value by retrofitting the product. In this case, the assistive device 100 may be adopted as a standard based on social approval.

FIG. 3 is a partially perspective rear view for explaining the height relationship between the belt and the screw cap of the auxiliary tool in the “fitted state”. FIG. 3A shows a basic example (barrel) of this auxiliary tool applied to a screw cap, for example, a 28φ fin lock cap, which is basically a parallel cylinder body and whose opening edge is slightly widened. (Shape expansion example), FIG. 3 (B) shows a chevron (trapezoidal when viewed from the front) cylinder with a larger outer diameter at the bottom than the top, and is suitable for a screw cap with a tamper evidence band attached to the opening edge. Modification examples of this auxiliary tool having a fixed claw are shown. The "fitting ring portion" of the present invention is mainly composed of a belt, and may be used with substantially the same meaning when explaining fitting and engagement with a screw cap.

The screw cap 10 with a wide opening edge shown in FIG. 3 (A) and the screw cap 9 with a non-wide opening edge (hereinafter, also referred to as “finlock cap”) 9 shown in FIG. Many screw caps of both shapes are widespread in Japan. A tamper evidence band 12 is also attached to the fin lock cap 9 in FIG. 3 (B), but it is omitted in FIG. 3 (A).

As shown in FIG. 3B, the lower edge of the belt 59, which mainly constitutes the auxiliary tool 101, is provided with an upward detachment prevention mechanism from the cylinder body portion 11. That is, a fixing claw 14 that can be engaged from below is projected from the opening edge of the fin lock cap 9. On the other hand, a tamper evidence band 12 is integrally molded at the lower part of the fin lock cap 9 when the cap is not opened via the initial coupling bridge 13. Since the fin lock cap 9 has a gap corresponding to the length of the initial coupling bridge 13, the auxiliary tool 101 (the same applies to the auxiliary tool 111 of FIG. 5B) has a fixing claw 14 in the gap. It is made engageable.

As a result, the auxiliary tool 101 is enhanced in the effect of preventing the screw cap 9 having a mountain-shaped gradient that easily comes off from coming off from the "fitted state". In other words, it should be fitted into the barrel of the screw cap, which had a chevron shape before closing or may be deformed into a barrel shape after closing, at a stage close to the bottling process, and then integrated into the bottle product. It is possible to provide a screw cap rotation assisting tool suitable for an "integrated type" product form to be distributed. The fixing claw 14 is not limited to a screw cap that has a chevron shape before closing or may be deformed into a barrel shape after closing. That is, even for a cylinder body having a uniform diameter from the upper side to the lower side, the effect of preventing the cylinder body from coming off from the cylinder body can be exhibited.

As shown in FIG. 3, the ring-fitting portion 50 with the auxiliary tool 100 of FIGS. 1 and 2 viewed from the rear is mostly composed of a belt 59 having a narrow width V. The width V of the belt 59 is narrower than 1/2 of the height H of the cylinder body portion 11 of the screw cap 10, and the entire circumference thereof below can be held parallel to the opening edge. That is, the average height of the ring fitting portion 50 is set to half or less of the height H of the cylinder body portion 11, and the lower end side of the ring fitting portion 50 is configured to be coordinateable in the vicinity of the opening edge of the screw cap 10. There is.

The fin lock cap 10 shown in FIG. 3A has a height H = 20.1 mm as an example. The belt 59 fitted in the vicinity of the opening edge is narrower than 1/2 of the height H, and has a width V = 5 mm as an example. Similarly, the screw cap 9 shown in FIG. 3B has a height H = 13 mm as an example. The belt 59 to be fitted so as to be aligned with the lower end can be fitted so that substantially the entire circumference of the lower side coincides with the opening edge of the screw cap 9. Its width V = 5 mm, which is narrower than 1/2 of the height H. As described above, the uniform region shown by the width V in FIG. 3 will be described later in FIG.

When the screw caps 9 and 10 shown in FIG. 3 are screwed to the male screw of the spout portion of the bottle, they are pushed by the male screw to expand the diameter. The degree of diameter expansion is such that the vicinity of 1/2 of the height H, that is, the middle abdomen of the cylinder body 11 is significantly expanded from the upper and lower ends and deformed into a barrel shape (difference X in FIG. 3). However, the belts 59 of the auxiliary tools 100 and 101 are provided with an upward detachment prevention mechanism from the cylinder body portion 11. That is, it is fitted to the constricted portion formed below the middle abdomen of the cylinder body portion 11. With such a detachment prevention mechanism, it is possible to prevent the detachment from the "fitted state".

In the auxiliary tools 100 and 101, the operation portion 30 is integrally molded and arranged on a ring fitting portion 50 mainly composed of a belt 59 narrower than 1/2 of the height H. The auxiliary tools 100 and 101 have a chevron shape before closing, or are 1/2 of the height H of the cylinder body 11 of the screw caps 9 and 10 which may be deformed into a barrel shape after closing. That is, the fitting ring portion 50 is fitted at a constricted position below the middle abdomen of the cylinder body portion 11, and the operating portion 30 is fixed.

As shown in FIG. 3A, the auxiliary tool 100 is set so that the thickness of the ring-fitting portion 50 gradually increases from the upper part to the lower part as a detachment prevention mechanism. Further, the inner diameter of the ring-fitting portion 50 is set so as to gradually narrow from the upper part to the lower part. As a result, it is possible to exert a function as a detachment prevention mechanism for preventing the detachment in the upward direction in a state where the middle portion of the cylinder body 11 is fitted to the screw cap 9 whose diameter is expanded in a barrel shape.

As a result, the fitting ring portion 50 may slip and fall off even if the force of the finger M trying to open the cap is excessive on the cylinder body portion 11 of the screw cap and acts upward in addition to the cap opening torque. not. As described above, the auxiliary tools 100 and 101 are suitable for a product form in which the auxiliary tools 100 and 101 are securely fitted with a belt-shaped belt and then distributed at a stage close to immediately after the bottling process, and the bottle product consumer will open the cap. It is possible to provide an easy-to-use screw cap rotation assisting tool without easily falling off by the force of the fingers.

FIG. 4 shows a modification of this auxiliary tool having a screw cap having the same basic shape as that of FIG. It is a rear view which shows an example. FIG. 4A shows a barrel-shaped expansion example, and FIG. 4B shows a chevron-shaped example. As shown in FIG. 4A, the auxiliary tool 102 is provided with an upward detachment prevention mechanism from the cylinder body portion. That is, the belt 60 on which the ridge 4 is projected is fitted into the groove 2 of the screw cap 15. With such a detachment prevention mechanism, the effect of preventing the user from unintentional dropout can be enhanced.

The auxiliary tool 102 shown in FIG. 4 can be fitted to screw caps 15 and 16 having one or more grooves 1, 2 and 3 formed so as to orbit the outer peripheral surface of the cylinder body 11 at the same height. Is. FIG. 4A shows a state in which the auxiliary tool 102 is fitted to a screw cap 15 having a groove 2 engraved in the middle of the cylinder body 11. Further, as shown in FIG. 4 (B), the auxiliary tool 102 is provided with a mechanism for preventing detachment from the cylinder body portion upward. That is, the auxiliary tool 102 is fitted to the screw cap 16 in which a total of three grooves 1 to 3 are engraved one by one parallel to the top and bottom of the groove 2 and at equal intervals. With such a detachment prevention mechanism, the effect of preventing the user from unintentional dropout can be enhanced.

On the inner peripheral surface of the belt 60 constituting the main part of the auxiliary tool 102, that is, the fitting surface, one ridge 4 corresponding to the grooves 1, 2, and 3 is projected. The grooves 1, 2, 3 and the ridges 4 illustrated in FIG. 4 all have a rectangular cross section, but a semicircular or triangular cross section (not shown) may be used. Further, the auxiliary tool 102 is integrally molded with polyethylene or the like, and the belt 60 can be elastically deformed to the extent that the ridges 4 are fitted into the grooves 1, 2, and 3.

In addition, in FIG. 4B, a total of three auxiliary tools 102 fitted in each of the three grooves 1 to 3 are shown, but three different forms are drawn together in one drawing. It's just that. That is, in reality, only one of the auxiliary tools 102 is fitted in only one of the three grooves 1 to 3 in the upper, middle, and lower parts for practical use.

Further, the relationship between the grooves 1, 2 and 3 shown in FIG. 4 and the ridge 4 may be reversed. That is, the place where the ridge 4 is projected on the belt 60 of the auxiliary tool 102 shown in FIG. 4 and the screw caps 15 and 16 are engraved with a total of one or three grooves 1 to 3 is reversed. You may let me. When the belt is reversed in this way, the grooves 1 to 3 are engraved on the belt 60, and the ridges 4 are projected on the screw caps 15 and 16. It should be noted that the effects in the case of reversal are almost the same, so the illustration is omitted.

As described with reference to FIG. 4, in the assisting tool 102, as a disengagement prevention mechanism, an engaging portion that engages with the screw caps 15 and 16 to prevent disengagement in the height direction is a fitting ring portion 60. Inside, a convex shape, for example, a ridge 4 is provided continuously, intermittently or partially in the circumferential direction to form a detachment prevention mechanism. The convex shape as the disengagement prevention mechanism, for example, the ridge 4 is provided with respect to the engaging receiving portion on the circumference provided continuously or intermittently at the intermediate portion and / or the lower end portion of the body cylinder portion of the screw caps 15 and 16. It is configured to be engageable.

Regarding the fixed claw 14 shown in FIG. 3B, the fixed claw 14 is convex inward in the radial direction inside the ring fitting portion 59, for example, the fixed claw 14 is continuous, intermittent or partial in the circumferential direction. It is provided in the above and constitutes a detachment prevention mechanism. The convex shape, for example, the fixing claw 14 as the disengagement prevention mechanism is provided continuously or intermittently at the intermediate portion and / or the lower end portion of the body cylinder portion 11 of the screw cap 9 with respect to the engaging receiving portion on the circumference. It is configured to be engageable. In particular, the fixing claw 14 has an engaging portion formed in the lower portion of the fitting ring portion 59.

FIG. 5 is a rear view showing a modified example of this auxiliary tool in which a screw cap having the same basic shape as that of FIG. 3 is covered over the entire height of the cylinder body and a lightening hole is formed in the fitting belt. be. The auxiliary tool 110 shown in FIG. 5A is fitted to a barrel-shaped screw cap 15. If it is tightly fitted to the outer periphery of the barrel shape in this way, it is sufficiently prevented from being detached upward from the barrel body portion. The auxiliary tool 111 shown in FIG. 5B is fitted to a chevron screw cap 16. The difference between the Auxiliary Tool 110 and the Auxiliary Tool 111 is that the effect of preventing disengagement is enhanced by the fixing claws 14 arranged on the lower edge of the Auxiliary Tool 111. The fixed claw 14 is as described above with reference to FIG. 3 (B).

As shown in FIG. 5B, a fixing claw 14 that can be engaged from below is projected from the lower edge of the belt 61 that mainly constitutes the auxiliary tool 111 to the opening edge of the screw cap 16. On the other hand, a tamper evidence band 12 is integrally molded at the lower part of the screw cap 16 when the cap is not opened via the initial coupling bridge 13. Since the screw cap 16 has a gap corresponding to the length of the initial coupling bridge 13, the auxiliary tool 101 (the same applies to the auxiliary tool 101 of FIG. 3B) engages the fixing claw 14 in the gap. It is possible.

As a result, the auxiliary tool 111 is enhanced in the effect of preventing the screw cap 16 having a chevron slope, which is easily dislodged, from being unintentionally dropped by the user. The fixing claw 14 is not limited to a screw cap that has a chevron shape before closing or may be deformed into a barrel shape after closing. That is, even for a cylinder body having a uniform diameter from the upper side to the lower side, the effect of preventing the cylinder body from coming off from the cylinder body can be exhibited.

The common points of the auxiliary tools 110 and 111 are as follows. The auxiliary tools 110 and 111 have a belt 61 having an area that covers the outer peripheral surfaces 18 of the screw caps 15 and 16 over 50% or more. Moreover, the belt 61 is provided with a lightening hole 62 that exposes 20% or more of the outer peripheral surface 18. The belt 61 having a lightening hole 62 having such a large area and a large area ratio has a good grip on the outer peripheral surfaces 18 of the screw caps 15 and 16. Therefore, there is an advantage that not only the opening torque is satisfactorily transmitted from the auxiliary tools 110 and 111 to the screw caps 15 and 16, but also the opening torque is hard to come off. Further, there is an effect of saving material by the amount of the lightening hole 62 having a large area ratio. In addition, the design is also excellent. As described above, the fitting portion mainly composed of the belt 61 is provided with a lightening hole 62 penetrating the front and back, but the lightening hole 62 may be non-penetrating.

6A and 6B show the auxiliary tool of FIG. 1 in an unused state, FIG. 6A is an overall plan view, and FIG. 6B is an enlarged plan view of a main part showing the vicinity of the fitting portion in an enlarged manner. be. As shown in FIG. 6A, the operation unit 30 can be directly or indirectly connected to the outer peripheral surface 18 of the screw cap 10 via the base end hinge 21. The operation unit 30 extends in a bow shape or a curved plate shape from the base end 31 to the tip end 32. The base end hinge 21 corresponds to the "first hinge portion" in the present invention.

The base end hinge 21 is formed so that the base end 31 of the operating portion 30 or the vicinity of the base end 31 is rotatably connected to a part of the outer peripheral surface 18. Further, in the operation unit 30, the length L from the base ends 31, 41 to the tips 32, 42 is 1/4 or more (of course, limited to this) with respect to the length πD of the entire circumference of the outer peripheral surface 18. Not.). In addition, π is the circumference ratio, and D is the diameter of the screw cap 10. More specifically, the diameter D of the screw cap 10 can be defined relatively easily and accurately by adopting the maximum value measured by a caliper or the like for the diameter D of the cylinder body portion 11 on which the knurl 19 is formed in the outer peripheral surface 18. can.

As shown in FIG. 6, the length L of the lever 33 from the base end 31 to the tip end 32 of the operation unit 30 corresponds to the central angle α + β. The central angle is α≈90 °, β≈10 °, and the central angle α + β≈100 °. From this setting, it is shown that the length L of the lever 33 is 1/4 or more with respect to the length πD of the entire circumference of the outer peripheral surface 18.

Although the diameter D is the maximum value in the vicinity of 40% from the top with respect to the height H of the screw cap 10 shown in FIGS. 8 and 9, the screw cap 10 is attached to the spout portion of the PET bottle body. It is the result of swelling for the first time by screwing. Therefore, the diameter D of the unclosed screw cap 10 is actually smaller than that of FIGS. 8 and 9 because there is no bulge.

The operation unit 30 of the auxiliary tool 100 is composed of a lever 33 made of a single rigid body from the base end 31 to the tip end 32. Further, the tip 32 of the operation unit 30 is formed with a warp portion 34 in the direction opposite to the arc at a length of 1/20 or more (of course, not limited to this) of the lever 33.

As shown in FIG. 6, the length J of the warped portion 34 of the operating portion 30 corresponds to a central angle β≈10 ° (of course, not limited to this). Further, the length L of the lever 33 is a central angle α + β≈100 ° (of course, the length L is not limited to this). From this setting, the tip 32 of the operation unit 30 is formed with a warp portion 34 in the direction opposite to the arc, which is 11 times (1/20 or more) as long as the lever 33.

FIG. 7 is a plan view showing a process in which the auxiliary tool of FIG. 1 is fitted to a screw cap and opened. The operation unit 30 maintains the first coordination form shown in FIGS. 1 to 6 and the second coordination form shown in FIG. 7, respectively, or changes from the first coordination form to the second coordination form. It is possible to make a transition as appropriate. Further, in FIGS. 1, 6 and 7, the wall thickness of the belt 59 is different between thin N and thick S depending on the location. That is, the uniform region of the belt 59 is formed with a thin wall thickness N, and the non-uniform region is made sturdy with a thick wall thickness S, and the hinge forming portion 51 for the base end is formed. It should be noted that the perspective view does not necessarily clearly indicate the magnitude relationship. A base end hinge 21 is erected on the base end hinge forming portion 51, and a lever 33 integrally molded with them is continuously provided. Further, the fact that the width W of the base end hinge forming portion 51 is formed as a widening region wider in the axial direction than the width V of the uniform region will be described later with reference to FIG.

When applying rotational torque (opening direction F) to the operation unit 30 of the auxiliary tool 100, the user can use not only the fingertip M but also the oral cavity, teeth, jaw, and corners of an object. can. As described above, for a person who is not good at operating the screw cap 10 for the container, the operation becomes extremely easy. Not only that, it is a product that is likely to be used as a fashion for young people.

The first coordination form is a shape in which a concentric arc (hereinafter, also simply referred to as “arc”) 24 (FIG. 6) with respect to the outer peripheral surface 18 is formed and folded when the screw cap 10 is unopened. The second coordination form is a shape in which the tip 32 or a position close to the tip 32 expands in the diameter expansion direction E when the screw cap 10 is opened.

Further, in the first coordination form, when the torque in the opening direction F is applied to the tip 32 or the position close to the tip 32 by the finger M of the person who operates the opening, the finger M slides in the opening direction F. It transforms into a difficult second coordination form. If the lever 33 in the second coordination form is pushed in the radial direction K and folded, it can be flexibly returned to the first coordination form.

As shown in FIG. 6, a recess 38 is provided on the surface of the auxiliary tool 100 facing the outer peripheral surface 18 in the vicinity of the tip 32 of the lever 33. A convex portion 28 is provided directly on the outer peripheral surface 18 at a position facing this, or if there is a pseudo outer peripheral surface 27 having a function equivalent thereto. The convex portion 28 and the concave portion 38 form a fitting portion 8 that can be fitted and removed freely. The fitting portion 8 can be fitted to maintain the first coordination form, and can be detached when the first coordination form is transformed into the second coordination form. In this way, the operation unit 30 is detachably and stably held with respect to the pseudo outer peripheral surface 27 at the appropriate portion inside the operation unit 30 and the opposite portion of the pseudo outer peripheral surface 27 facing the appropriate portion. The fitting portion 8 is provided.

When the consumer with respect to the contents of the bottle opens the bottle for the first time, the operation unit 30 is transformed from the first coordination form to the second coordination form having an enlarged diameter. Depending on the usage pattern of the consumer, it may be more convenient to reduce the diameter from the expanded second coordination form and return to the first coordination form. In that case, the fitting portion 8 is beneficially effective. When the cap is opened for the second time or later, the fitting portion 8 is removed, and when the cap is closed, the fitting portion 8 is fitted. Since the fitting portion 8 is flexibly molded, the usage pattern thereof is free for the consumer.

As shown in FIG. 6B, since the dimensional difference is set at the position where the convex portion 28 and the concave portion 38 constituting the fitting portion 8 are intentionally engaged with each other, some pressure is applied from the outer peripheral side of the lever 33. By adding, the dimensional difference is absorbed by the amount of deformation of the base end hinge 21 and the lever 33, and the two are engaged with each other. Since the dimensional difference is set between the convex portion 28 and the concave portion 38, even if the initial coupling bridge 81 is arranged at the tip of the convex portion 28, it does not hinder the engagement of the fitting portion 8 and also works beneficially. do.

The initial coupling bridge 81 is configured to stably connect and hold the operation unit 30 when not in use. Further, when the auxiliary tool 100 is used for the first time, the initial coupling bridge 81 is configured to be extremely fine so as to be easily torn. Further, if the broken piece of the broken initial coupling bridge 81 remains at the tip of the convex portion 28, it can be utilized as a mechanism for engaging with the concave portion 38 as a part of the convex portion 28.

FIG. 8 is a front view showing a state in which the auxiliary tool of FIG. 1 is fitted to a screw cap and has not been opened. FIG. 9 is a left side view showing the auxiliary tool of FIG. As shown in FIGS. 8 and 9, the ring fitting portion 50 is mainly composed of a belt 59.

The width V of the belt 59 is narrower than the height H of the cylinder body portion 11 of the screw cap 10. A hinge forming portion 51 for the base end is specially provided in the middle of the belt 59. The width W of the hinge forming portion 51 for the base end is narrower than the height H of the cylinder body portion 11, but a widening portion wider than the width V of the belt 59 is formed. That is, the base end hinge forming portion 51 has a widening portion in which the length in the axial direction is set longer than the average height of the fitting ring portion 50. The base end hinge 21 shown in FIGS. 6 and 7 is erected on the base end hinge forming portion 51. The wall thickness S of the hinge forming portion 51 for the base end is formed to be thicker and stronger than the wall thickness N of the uniform region of the belt 59, which is the same as the auxiliary tools 100 and 101 of the first embodiment.

As shown in FIGS. 1 to 9, the auxiliary tool 100 according to the first embodiment has an operation unit 30 that is separate from the general screw cap 10, such as a cap maker, a PET bottle maker, a bottling factory, and a distributor. , It is preferable to use it for post-processing at retail stores.

Further, in the auxiliary tool 100, the operation unit 30 is arranged on the pseudo outer peripheral surface 27. In addition, the screw cap 10, the fitting ring portion 50 to be tightly fitted to the screw cap 10, and the knurls 19 and 29 coincide with each other on the fitting surfaces of both. Moreover, in the unopened state, it is maintained in the first coordination form. In the first coordination form, the lever 33 forming the operation unit 30 is folded in the diameter reduction direction K, and in the second coordination form, it expands in the diameter expansion direction E.

At the time of opening the cap for the first time, the operation unit 30 is deformed from the first coordination form to the second coordination form with an expanded diameter, and the opening is facilitated by the action of a large force moment according to the principle of leverage. Therefore, the auxiliary tool 100 can satisfactorily transmit the rotational torque from the finger M, the operation portion 30, and the ring fitting portion 50 to the screw cap 10.

According to the present invention, the screw cap rotation suitable for the "integrated type" product form in which the screw cap is fitted to the cylinder body of the screw cap at a stage close to the bottling process, integrated into the bottle product, and then distributed. Auxiliary equipment can be provided. In other words, even if the force of the finger of the person who opens the screw cap is weak, the moment is increased by this auxiliary tool with a wider turning radius, so the torque required to open the screw cap can be reliably and easily applied. Is possible. In particular, it is suitable for a screw cap that has a chevron shape before closing or that deforms into a barrel shape after closing.

Further, in the auxiliary tool 100, the operation unit 30 is arranged on the pseudo outer peripheral surface 27 (FIG. 6). In addition, the screw cap 10, the fitting ring portion 50 to be tightly fitted to the screw cap 10, and the knurls 19 and 29 coincide with each other on the fitting surfaces of both. Moreover, in the unopened state, it is maintained in the first coordination form. In the first coordination mode, the lever 33 forming the operation portion 30 has a base end hinge 21 erected on a pseudo outer peripheral surface 27 separate from the screw cap 10.

Here, the main points of the present invention will be described. The auxiliary tools 100, 101 and the like according to the first embodiment shown in any one of FIGS. 1 to 9 transmit torque in the opening direction F to the screw caps 9, 10 and the like. The auxiliary tools 100, 101 and the like are configured to include a ring fitting portion 50, an operating portion 30, and a hinge portion (base end hinge 21).

The ring fitting portion 50 can be fitted to the outer peripheral surface 18 of the screw caps 9, 10 and the like, and is formed with an idling prevention portion, for example, knurls 19 and 29, which prevents slipping in the circumferential direction with respect to the outer peripheral surface 18. .. The slip prevention portions (knurls 19 and 29) are provided on the inner and outer peripheral surfaces of both of the fitting portions and can be engaged with each other.

The operation portion 30 formed by the lever 33 or the like can function as a pseudo outer peripheral surface having substantially the same function as the outer peripheral surface 18 of the screw caps 9, 10 and the like on the outer periphery of the ring fitting portion 50. That is, the operation unit 30 (lever 33 or the like) extends from the base end 31 to the tip end 32 along the pseudo outer peripheral surface 27. As described above, the operating portion 30 (lever 33 and the like) is arranged on the pseudo outer peripheral surface 27 forming the outer peripheral surface of the ring fitting portion 50.

The hinge portion (hinge 21 for the base end) connects the operation portion 30 and the pseudo outer peripheral surface 27 to the base end 31 or the vicinity of the base end 31 of the operation portion 30 (lever 33, etc.), and the operation portion (lever 33, etc.). Etc.) are rotatably supported.

Further, the ring fitting portion 50 is formed with a detachment prevention mechanism (for example, a fixing claw 14 or the like) for preventing the screw caps 9 and 10 from detaching from the cylinder body portion 11. Further, the operation unit 30 (lever 33 or the like) is configured to be able to maintain or transition to the first coordination form and the second coordination form, respectively.

This first coordination form is a form in which the pseudo outer peripheral surface 27 is brought close to the pseudo outer peripheral surface 27. Further, in the second coordination mode, the operation portion 30 (lever 33 or the like) is rotated around the hinge portion (base end hinge 21) as a fulcrum, and the tip 32 is separated from the pseudo outer peripheral surface 27 in the diameter expansion direction. It is an expanded form.

The auxiliary tool 100 can also obtain the following effects by the configuration as described above.
<1> In the first coordination form in which the operation portion 30 is folded along the ring portion 50, the urging force is applied in a direction in which the convex portion 28 and the concave portion 38 constituting the fitting portion 8 are difficult to separate from each other. Occurs. As a result, the force for holding the engaged portion 8 is improved, and during mounting, storage, transportation, display, storage in bags, pockets, etc., storage in vending machines, etc., and operation. Unintentional withdrawal can be suppressed.

<2> After use, if the operating portion 30 is brought closer to the fitting portion 50 again and some pressure is applied, the fitting portion 8 can be engaged with a comfortable impact sound of "click". At this time, the user needs to push in with some force, and when the two engage with each other, an appropriate click feeling can be obtained. For this reason, the engagement state of the two can be confirmed by the resistance to the finger M and the sound, and the user can use it with peace of mind.

<3> The same applies to the case where the fitting portion 8 is detached, and the light impact transmitted to the finger M becomes a pleasant sensation, so that higher commercial value can be provided.

<4> The initial coupling bridge 81 can prevent unintentional detachment during mounting, storage, transportation, display, storage in a bag, pocket, or the like, storage in a vending machine, or operation. Further, the initial coupling bridge 81 can determine whether it is unused or used.

<5> In particular, a dimensional difference or a positional difference is set between the convex portion 28 and the concave portion 38 constituting the fitting portion 8 in relation to engagement. Therefore, the setting position of the initial coupling bridge 81 can be set at the tip of the convex portion 28. As a result, when not in use, the operation unit 30 is stably held along the ring-fitting portion 50 in a substantially circular shape. In addition, the initial coupling bridge 81 can be easily torn during use. The initial coupling bridge 81 means an "easy-breaking portion" in the present invention. Here, if the structure is such that the torn piece of the initial coupling bridge 81 that has been torn remains at the tip of the convex portion 28, it can be utilized as a mechanism for engaging with the concave portion 38 as a part of the convex portion 28.

<6> If the initial coupling bridge 81 is provided, it is possible to reduce one processing step of engaging the convex portion 28 constituting the fitting portion 8 with the concave portion 38 in advance, which is desired to be eliminated before shipment.

<7> Further, at the time of use, an external force equal to or higher than the set value is applied to the operation unit 30 to rupture the initial coupling bridge 81. By this sensation of tearing, it can be confirmed that the auxiliary tool 100 is unused. In particular, when the ring-fitting portion 50 is an integral type forming the body cylinder portion of the screw cap of the container, it can be confirmed that the screw cap is not opened by the feeling of this tear. The initial coupling bridge 81 can also be expected to have tamper evidence.
[Second Embodiment]

Hereinafter, the second embodiment will be described with reference to FIGS. 10 to 13. FIG. 10 is a front view showing an unused state of the screw cap rotation assisting tool (this assisting tool) according to the second embodiment of the present invention. FIG. 11 is a diagram illustrating the auxiliary tool of FIG. 10, and is a perspective view showing an unused state. 12A and 12B are plan views showing the auxiliary tool of FIG. 11 in an unused state, FIG. 12A shows a basic shape, and FIG. 12B shows a modified example. FIG. 13 is a plan view showing a process in which the auxiliary tool of FIG. 11 is fitted to the screw cap and opened.

As shown in FIGS. 10 to 13, the auxiliary tool 200 according to the second embodiment also has a ring-fitting portion 50, which is different from the general screw cap 10, and is distributed by a cap maker, a PET bottle maker, a bottling factory, and a distribution facility. It is a usage method for retrofit processing at vendors, retail stores, etc.

Further, the auxiliary tool 100 and the auxiliary tool 200 are similarly similar in that the operation portion 40 is arranged on the pseudo outer peripheral surface 27. The same applies to the point that the screw cap 10, the fitting ring portion 50 to be tightly fitted to the screw cap 10, and the knurls 19 and 29 coincide with each other on the fitting surfaces of both. Moreover, in the unopened state, it is maintained in the first coordination form.

Further, the first coordination form is a shape in which the screw cap 10 is folded by forming a concentric arc 25 with respect to the outer peripheral surface 18 when the screw cap 10 is unopened. In the second coordination form, when the screw cap 10 is opened, the positions 43 and 44 near the tip 42 are expanded in the diameter expansion direction E (FIG. 13). Further, the initial coupling bridge 82 is arranged at a position 43 near the tip 42, and the operation unit 40 is stably connected to and held on the pseudo outer peripheral surface 27 when not in use. The function of the initial coupling bridge 82 is as described in the first embodiment.

In the first coordination mode shown in FIG. 12 (A), the operation unit 40 is folded in the diameter reduction direction K (FIG. 13), and in the second coordination mode shown in FIG. 13, it is in the diameter expansion direction E. Expand to. The same applies to the fact that when the cap is opened for the first time, it is deformed from the first coordination form to the second coordination form, and the action of a large moment due to the diameter expansion effect facilitates the opening. Therefore, the auxiliary tool 200 can satisfactorily transmit the rotational torque from the finger M, the operation portion 40, and the ring fitting portion 50 to the screw cap 10 in the same manner as the auxiliary tool 100.

The length from the base end 41 to the tip end 42 of the operation unit 40 is also 1/4 or more (of course, not limited to this) with respect to the length πD of the entire circumference of the outer peripheral surface 18. Here, the lengths of the arcs are compared at their respective central angles. As shown in FIG. 12, the length from the base end 41 to the tip end 42 of the operation unit 40 also corresponds to the central angle θ ₁ + 2 · θ ₂ because the folded parts are added together. The central angle is θ ₁ ≈ 90 °, θ ₂ ≈ 30 °, and the central angle θ ₁ + 2 · θ ₂ ≈ 150 °. From this setting, it is shown that the length from the base end 41 to the tip end 42 is 1/4 or more (of course, not limited to this) with respect to the length πD of the entire circumference of the outer peripheral surface 18. ..

Note that FIG. 12 shows a state in which the ring-fitting portion 50 of the operation portion 40 is not fitted to the screw cap 10, so that the outer peripheral surface 18 of the screw cap 10 is not clearly shown. However, since the state of being fitted to the screw cap 10 is clearly shown by FIG. 13, this point can be easily estimated.

Further, as is clear from FIG. 12, the length from the base end 41 to the second section 44 is the length from the tip 42 to the first section 43 and the length from the first section 43 to the second section 44. Longer than the length you did. Again, the arc lengths are compared at their respective central angles. The length from the base end 41 to the second node 44 corresponds to the central angle θ ₁ . Similarly, the lengths from the tip 42 to the first section 43 and from the first section 43 to the second section 44 both correspond to the central angle θ ₂ . The central angle θ ₁ ≈ 90 °, and the central angle θ ₂ ≈ 30 °. Here, the central angle θ ₁ ≈ 90 °> the central angle θ _2.2 ≈ 60 °. From this setting, the length from the base end 41 to the second section 44 is longer than the total length of the tip 42 to the first section 43 and the length from the first section 43 to the second section 44.

Hereinafter, only the characteristic configuration of the auxiliary tool 200 according to the second embodiment will be described. The auxiliary tool 200 is further provided with a tip hinge 22 for rotatably connecting the tip 42 to a part of the outer peripheral surface 18 away from the base hinge 21. The tip hinge 22 means the "second hinge portion" in the present invention. Further, the first section 43 and the second section 44, which can be bent and extended, are formed in order from the one closest to the tip 42. The flexible band-shaped portion from the tip 42 to the second section 44 means the "connecting band" in the present invention. Of course, the connecting band does not necessarily have to be flexible as a whole, as long as it is configured to be able to bend and extend, and it goes without saying that it may include a rigid portion.

The connecting band has a substantially C-shape, a substantially J-shape, and a substantially L shape, which are extended in the circumferential direction of the operation portion or warped so as to overlap the operation portion when the operation portion is in the first coordination form. Glyph, glyph M, glyph N, glyph S, glyph U, glyph V, glyph W, glyph Z, glyph m, glyph n, glyph r, inverted V, glyph π , Abbreviated Σ-shaped, abbreviated Y-shaped, abbreviated Ω-shaped, abbreviated, abbreviated, abbreviated, abbreviated, abbreviated, abbreviated, abbreviated, abbreviated, abbreviated It is configured to be in a bent shape (a non-extended posture) consisting of a bent shape or a combination thereof.

Further, rigidity is ensured by forming the base end 41 to the second node 44 thickly in the radial direction of the screw cap 10, and flexibility is ensured by forming the tip 42 to the second node 44 thinly. Has been done. These flexions and extensions are distinguished by a first coordinated form and a second coordinated form. That is, in the first coordination form, the first section 43 is bent in a substantially U shape, and the second section 44 is linearly extended. Further, in the second coordination form, the first section 43 advances linearly and the second section 44 bends.

Further, in the first coordination form, the torque in the opening direction F is applied to the tips 42 or the positions 43, 44 (sections 43, section 2 44) near the tip 42 or the tip 42 by the finger M of the person who opens the plug. When applied, the finger M is deformed into a second coordination form having a shape that does not slip easily in the opening direction F. If the first section 43 and the second section 44 of the second coordination form are pushed in the radial direction K and folded, the first section 43 and the second section 44 can be flexibly returned to the first coordination form.

In this way, the hinge for the tip 22 connects the fitting ring portion 50 and the operating portion 40 to each other at a position other than the hinge for the base end and stably fixes the fitting ring portion 50 and the operating portion 40. Is one with. Therefore, it is possible to prevent the operation unit 40 when not in use from being unintentionally rotated or caught inside the vending machine or the bag, during storage, transportation, or the like. In the ring fitting portion 50, the wall thickness S at the portion where the tip hinge 22 is arranged is formed to be thicker and stronger than the wall thickness N in the uniform region of the belt 59. This point is the same as that of the base end hinge forming portion 51.

Here, the main points of the invention according to the second embodiment will be described. In the auxiliary tool 200 shown in FIGS. 11 to 13, the operation portion 40 includes a rigid portion and a connecting band. The rigid portion is a lever-shaped body having a relatively high rigidity from the base end 41 of the operation portion 40 to the second section 44. Further, as described above, the connecting band according to the present invention has a first section 43 and a second section 44, which can be bent and extended, respectively, in order from the side closer to the tip 42 of the operation unit 40. It is a flexible band.

One end of the connecting band is connected to the tip (second section 44) of the rigid portion of the operating portion 40, and the other end is an appropriate portion (tip 42) on the pseudo outer peripheral surface 27 of the fitting ring portion 50. It is configured by being connected to the tip hinge 22). Further, the connecting band is formed by rotating the operating portion 40 with the hinge portion (hinge for the base end 21) as a fulcrum, and connecting the tip of the rigid portion (section 2 44) of the operating portion 40 with the connecting portion (hinge for the tip 22). ) And can be expanded.

When the operation unit 40 is in the first coordination form, the connecting band of the auxiliary tool 200 has a substantially U-shaped posture in which the operation unit 40 is extended in the circumferential direction or warped so as to overlap the operation unit 40. It is configured as follows. As shown in FIG. 12, the connecting band of the auxiliary tool 200, that is, the flexible band-shaped portion from the tip 42 to the second section 44, is thinner than the average wall thickness of the operating portion 40. Can be set.

Further, with respect to the basic shape shown in FIG. 12 (A), in the modified example shown in FIG. 12 (B), in the first coordination form in which the first section 43 is folded, a warp in the direction opposite to the arc 25 is provided. As a result, the user's fingers are easily hooked. This point is also the same as the configuration in which the auxiliary tool 100 shown in FIG. 6 has a warped portion 34 formed in the direction opposite to the arc 24.

Then, when the auxiliary tool 200 is used for the first time, an external force equal to or higher than the set value is applied to the operation unit 40 to rupture the initial coupling bridge 82. By this sensation of tearing, it can be confirmed that the auxiliary tool 200 is unused. That is, the initial coupling bridge 82 can be provided with tamper evidence and can play its role.

The operation unit 40 of the auxiliary tool 200 may be combined with belts 60 and 61 having different shapes as described above. The above-mentioned belt 60 has ridges 4 arranged on the inner peripheral surface, and the above-mentioned belt 61 is wide and has a lightening hole 62. Further, the fixing claws 14 may be arranged on the lower edges of the belts 59 and 61.

[Third Embodiment]
Next, the third embodiment will be described with reference to FIG. 14A and 14B are views for explaining the present auxiliary tool according to the third embodiment of the present invention, FIG. 14A is an overall plan view in an unused state, and FIG. 14B is fitted and opened by a screw cap. It is a top view which shows the middle of plugging. The auxiliary tool 300 shown in FIG. 14 is a lever 33 of the auxiliary tool 100 according to the first embodiment shown in FIGS. 6 and 7 extended long from the base end 31. That is, in the auxiliary tool 300, the base end 31 is separated from the hinge 21, and the action point 37 is formed at the separated position. As a result, the auxiliary tool 300 can be opened with a smaller force than the auxiliary tool 100. More details are as follows.

In the case of the auxiliary tool 100 according to the first embodiment shown in FIG. 7, a part of the force of the finger M applied when opening the cap is such that the base end 31 directs the pseudo outer peripheral surface 27 toward the center O of the screw cap 10. While pressing in the normal direction, it acts in the normal direction away from the center O so as to pull out the hinge 21. Therefore, not all of the force of the finger M acts on the opening torque in the opening direction F, and a loss occurs, so that a larger force is required, which is somewhat disadvantageous.

On the other hand, in the auxiliary tool 300 shown in FIG. 14, by providing the action point 37 at a position away from the hinge 21, the component force in the normal direction wasted by the auxiliary tool 100 is reduced. , The force of the finger M applied at the time of opening can be applied more efficiently as the opening torque in the opening direction F. As a result, the auxiliary tool 300 can be opened with a smaller force than the auxiliary tool 100. The length from the hinge 21 to the point of action 37 is illustrated by setting the central angle γ of the ring-fitting portion 50 to ≈45 °, but the length is not limited to this, and the central angle γ ≦ 90 ° may be used. ..

[Fourth Embodiment]
Next, the fourth embodiment will be described with reference to FIG. 15A and 15B are views for explaining the present auxiliary tool according to the fourth embodiment of the present invention, FIG. 15A is an overall plan view in an unused state, and FIG. 15B is fitted and opened by a screw cap. It is a top view which shows the middle of plugging. In the auxiliary tool 400 shown in FIG. 15, the action point 39 of the lever 35 of the auxiliary tool 300 according to the third embodiment shown in FIG. 14 is extended further, and the action point 39 is set on the pseudo outer peripheral surface 27. It is a joint. The length from the hinge 21 to the point of action 39 is illustrated by setting the central angle δ≈90 ° of the ring-fitting portion 50, but the length is not limited to this, and the central angle δ≤90 ° may be used. ..

In the auxiliary tool 400, the curvature of the shape from the hinge 21 to the point of action 39 changes slightly between the unused state shown in FIG. 15 (A) and the opening of the stopper shown in FIG. 15 (B). Therefore, even if it is a thin, thin and simple structure, it is mechanically robust against deformation stress due to use. Further, the effect of ensuring a considerable length from the hinge 21 to the point of action 39 is equal to or higher than that of the auxiliary tool 300 according to the second embodiment. That is, the auxiliary tool 400 can also be opened with less force than the auxiliary tool 100.

[Fifth Embodiment]
Next, a fifth embodiment will be described with reference to FIG. 16A and 16B are views for explaining the present auxiliary tool according to the fifth embodiment of the present invention, FIG. 16A is an overall plan view in an unused state, and FIG. 16B is fitted and opened by a screw cap. It is a top view which shows the middle of plugging. In the auxiliary tool 500 shown in FIG. 16, the hinge 21 of the auxiliary tool 300 according to the second embodiment shown in FIG. 14 is extended approximately twice, and is obliquely deflected toward the tip 32 of the lever 35. It is replaced with an obliquely long deflection type hinge 23 joined to the pseudo outer peripheral surface 27.

The auxiliary tool 500 according to the fifth embodiment has a length from the oblique deflection type hinge 23 to the point of action 37, rather than the length from the hinge 21 of the auxiliary tool 300 according to the second embodiment to the point of action 37. , Can be secured for a longer time. Therefore, the effect of the auxiliary tool 500 according to the fifth embodiment is equal to or higher than that of the auxiliary tool 300 according to the second embodiment. That is, the auxiliary tool 500 can also be opened with less force than the auxiliary tools 100 and 300.

[Sixth Embodiment]
Next, the sixth embodiment will be described with reference to FIGS. 17 and 18. FIG. 17 is a view for explaining the present auxiliary tool according to the sixth embodiment of the present invention, and is a plan view showing the process of fitting the screw cap and opening the cap. FIG. 18 is a perspective view showing an unused state of the auxiliary tool of FIG. The auxiliary tool 600 shown in FIGS. 17 and 18 divides the belt 59 of the auxiliary tool 100 according to the first embodiment shown in FIGS. 6 and 7 into about 10 divisions in the circumferential direction, and has a circumference. It has a belt 70 in which thin-walled portions P are alternately provided for each division along the direction.

Even when the diameter of the belt 70 is forcibly increased to a large extent, the auxiliary tool 600 can be extended and adjusted by the thin portion P without difficulty. It should be noted that the division into 10 divisions is only an example here, and good results can be obtained even with 12 divisions, and for example, any of 2 to 20 divisions may be used. The action and effect divided into the cases with and without the thin-walled portion P will be described below in comparison. When there is no thin-walled portion, the auxiliary tool 100 according to the first embodiment shown in FIG. 3A is illustrated. On the other hand, when there is a thin-walled portion, the present auxiliary tool 600 according to the sixth embodiment shown in FIGS. 17 and 18 is exemplified.

In the present auxiliary tool 100 according to the first embodiment shown in FIG. 3 (A), when the difference X whose diameter is expanded to the barrel shape on the middle side of the cylinder body 11 of the screw cap 10 is extremely excessive, the cylinder body When the ring portion 50 is forcibly fitted through the middle portion of the portion 11, there is a problem that the belt 59 is cut beyond the limit applicable to the expansion of the diameter of the belt 59 in the diameter expansion direction.

On the other hand, even in the auxiliary tool 600 shown in FIGS. 17 and 18, when the difference X in which the middle portion of the cylinder body 11 of the screw cap 10 is expanded in a barrel shape is extremely excessive, the belt 70 is increased. Elongation stress that expands the diameter is strongly applied. The thin wall portion P is configured to have a wall thickness N of most of the other thicknesses and a wall thickness P (also used as a reference numeral) of about 20% thinner than the wall thickness S of the hinge forming portion 51 for the base end.

Further, in order to rotate the fitting ring portion 50 and the screw cap 10 together without idling, ribs (knurls 19) or knurls 29 extending in the axial direction are provided on the entire circumference. As a result, the inner peripheral surface of the ring-fitting portion 50 can engage with the outer peripheral surface 18 of the cylinder body portion 11 of the screw cap 10 and rotate together without idling.

At least one thin-walled portion P on which the ribs or knurls 19, 29 are not formed is provided inside the ring-fitting portion 50. Further, the wall thickness P (also used as a reference numeral) of the thin wall portion P is set to be thinner than the wall thickness N of the groove portion (rib or knurl 29). As a result, it is possible to cope with a slight difference in the outer diameter of the cylinder body portion 11 of the screw cap 10 while expanding and contracting. That is, the external adjustment mechanism is configured so that the fitting ring portion 50 can be properly fitted to the cylinder body portion 11 of the screw cap 10.

By providing this external adjustment mechanism, it is possible to solve the problem that when the fitting ring portion 50 is fitted to the cylinder body portion 11 of the screw cap 10, the fitting is extremely tight and cannot be fitted or becomes difficult. That is, it is possible to comfortably fit a place where the fitting condition is tight. That is, since an unintended stress load is not applied to the hinge portion, there is no possibility that the base end hinge 21 will be torn when the lever 33 is operated.

Therefore, the thin portion P increases the ductility inherent in a material such as polyethylene in both ductility and malleability. That is, it increases the limit of flexible deformation and expansion of the belt 70 without breaking. That is, it can be explained from the fact that a plastic bucket, which is a thick material, has little malleability, but a plastic bag, which is a thin material, can secure a considerable malleability. The optimum thickness of the thin portion P is specified for each of the width V of the belt 70 (see FIG. 3 and others) and the material.

[7th Embodiment]
Next, the seventh embodiment will be described with reference to FIG. FIG. 19 is a diagram illustrating the assisting tool according to the seventh embodiment of the present invention, and is a rear view showing a modified example in which a skirt is extended to the lower edge portion of the assisting tool having the same basic shape as that of FIG. be. FIG. 19A shows a barrel-shaped expansion example, and FIG. 19B shows a chevron-shaped example. The auxiliary tool 102 of FIG. 4 used for the base is only an example, and the auxiliary tools 100 and 101 of FIGS. 1 to 3 may be used as the base. It should be noted that FIG. 19B merely illustrates how the chevron screw cap 16 is fitted to any one of high, medium and low, at three points.

As shown in FIG. 19, the auxiliary tool 700 has a funnel shape in which the opening portion of the lower edge portion of the auxiliary tool 102 shown in FIG. 4 is diagonally enlarged as compared with other average inner diameters. The skirt is extended. Such a skirt has an effect of attracting a fitting object having a certain degree of core blur to absorb the core blur and facilitate and secure the fitting. Needless to say, the effect of the auxiliary tool 700 with a skirt shown in FIG. 19 is more remarkable than that of the auxiliary tool 102 without a skirt shown in FIG. As a result, the auxiliary tool 700 can easily adapt to the operation of a high-speed tapping machine or the like capable of tapping the screw caps 15 and 16 at a speed of 10 per second.

[Eighth Embodiment]
Next, the eighth embodiment will be described with reference to FIG. FIG. 20 is a diagram illustrating the present auxiliary tool according to the eighth embodiment of the present invention, and is a perspective view showing an unused state. As shown in FIGS. 1, 2, 8 and 9, the hinge forming portion 51 for the base end has a height W, which is higher than the width V of the belt 59. Therefore, most of the height of the ring-fitting portion 50 is not uniform in the circumferential direction of the belt 59, and the hinge forming portion 51 having a protruding height (width) W with respect to most of the height (width) V. Exists.

This means that the ring-fitting portion 50 has a phase in the circumferential direction. Therefore, in mass production equipment, some phase defining means for defining the phase is required. More specifically, it becomes particularly important when acclimatizing to the operation of a high-speed tapping machine or the like capable of tapping at a speed of 10 per second described above. That is, the auxiliary tool 100 shown in FIGS. 1, 2, and 9 needs to be gripped after undergoing a phase matching step in the gripping device of the type that covers the auxiliary tool 100 from above.

On the other hand, in the auxiliary tool 800 according to the eighth embodiment of FIG. 20, widening portions 91 and 92 having a height W equivalent to that of the hinge forming portion 51 for the proximal end are provided symmetrically in the circumferential direction due to a phase difference of 120 °. It is arranged. However, even in the widening portions 91 and 92 having a height W arranged symmetrically in the circumferential direction with a phase difference of 120 °, some phase defining means for defining the phase is required in the mass production apparatus.

However, as in the auxiliary tool 100 shown in FIGS. 1, 2, 8 and 9, the width of the belt 59 is not uniform in the circumferential direction and protrudes with respect to most of the height (width) V. Compared with the case where only one hinge forming portion 51 having a height (width) W is present, the auxiliary tool 800 having a circumferential symmetry with a phase difference of 120 ° can further simplify the phase defining means. More specifically, it becomes clear when comparing the phase correction angles required for phase matching. That is, when only one hinge forming portion 51 having a protruding height (width) W exists in the circumferential direction as in the auxiliary tool 100 shown in FIGS. 1, 2, 8 and 9. Where a maximum phase correction angle of 180 ° is required, in the present auxiliary tool 800 according to the eighth embodiment, the phase correction angle is 1/3 of that, and a maximum phase correction angle of 60 ° is sufficient.

[9th Embodiment]
Next, the ninth embodiment will be described with reference to FIG. 21 is a diagram illustrating the present auxiliary tool according to the ninth embodiment of the present invention, FIG. 21 (A) is a perspective view showing an unused state, and FIG. 21 (B) is a front view thereof. Is. The auxiliary tool 900 shown in FIG. 21 turns the auxiliary tool 200 according to the second embodiment shown in FIG. 11 upside down, and when the screw cap in the closed state is visually recognized from above and rotated counterclockwise, that is, in the opening direction. In addition, it is configured to facilitate torque transmission from the fingers.

The auxiliary tool 900 shown in FIG. 21 has only one hinge forming portion 51 having a protruding height (width) W with respect to most of the height (width) V, but it protrudes downward. It is possible to grip the gripping device of the type that covers from above without going through the step of phase matching. In addition, it is inevitable that the fitting form is raised from the lower part of the screw cap by the difference between the hinge forming portion 51 having a height (width) W protruding downward and most of the height (width) V. However, it can be adopted if it is judged that there is no problem.

Hereinafter, the tenth to thirteenth embodiments will be described with reference to FIGS. 22 to 27. The rotation assisting caps 210, 310, 410, 510 according to the tenth to thirteenth embodiments shown in FIGS. 22 to 27 are the present auxiliary according to the above-mentioned first to ninth embodiments shown in FIGS. 1 to 21.

The following three points have been added to the auxiliary tool 890. The first improvement point was that the three widening portions including the hinge forming portion 51 for the base end and the widening portions 91 and 92 in the auxiliary tool 800 according to the eighth embodiment shown in FIG. 20 were projected upward. However, the point is that the base end hinge widening portion 851, the tip hinge widening portion 842, and the widening portion 891 are projected downward in a tripod shape. Of course, the number of widening portions and the vertical orientation of the protrusions are not particularly limited.

The second improvement is that these three downward widening portions, that is, the base hinge widening portion 851, the tip hinge widening portion 842, and the widening portion 891 all have a tapered shape whose tip side is thinner than the base end side. The diameter of the virtual inscribed circle connecting the two is large on the tip side and small on the base end side. Therefore, in the auxiliary tool 890, even if the central axis is displaced in the process of integrating with the screw cap 10, the head of the cap 10 is easily attracted and fitted in the range of, for example, about 1 to 2 mm. I can wear it.

The third improvement is that these three downward widening portions, that is, the base end hinge widening portion 851, the tip hinge widening portion 842, and the widening portion 891 are central angles Q, R, arranged with respect to the circumferential direction. T (FIG. 28) is not necessarily limited to a uniform 120 °.

The reason why the auxiliary tool 800 arranges the three downward widening portions evenly at 120 ° is that by further simplifying the phase defining means, it is possible to tap at a speed of about 10 per second described above. This is to facilitate adaptation to the operation of a high-speed plugging machine or the like.

On the other hand, in the present auxiliary tool 890 according to the 14th embodiment, it is not always necessary to limit the three downward widening portions to a uniform 120 °. The reason is that the three downward widening parts do not come into direct contact with a high-speed plugging machine, etc., but rather, it is sufficient if they can be kept horizontal when placed on a horizontal and flat table. Because.

As for the auxiliary tool 890 according to the 14th embodiment, the auxiliary tool 800 according to the 8th embodiment shown in FIG. 20 or the auxiliary tool 900 according to the 9th embodiment shown in FIG. 21 is a screw cap 10. It has the same or better effect as the one fitted in. Equivalent action and effect means that both of these bring about the same usability for the end consumer, that is, the opening assist effect.

Further, the action / effect equal to or higher than that is the action / effect that facilitates adaptation to the operation of the high-speed tapping machine or the like capable of tapping at a speed of about 10 per second described above. That is, in the process of integrating with the screw cap 10, even if a core deviation occurs in which the central axis is displaced, the head of the cap 10 can be easily attracted and fitted within a certain range.
