Description

  The present invention relates to a bar-shaped cosmetic material feeding container that houses a bar-shaped cosmetic material such as a lipstick and a stick foundation, and that has a rotary feeding mechanism that moves up and lowers the bar-shaped cosmetic material by relatively rotating the container. The present invention relates to a stick-shaped cosmetic material delivery container that improves the sense of quality when used.

  A bar-shaped cosmetics feeding container that houses a bar-shaped cosmetic such as lipstick and stick foundation, and that has a rotary feeding mechanism that raises and lowers the bar-shaped cosmetic by rotating the container relative to each other. As a standard product, the cost was reduced, and this payout structure was mounted on an exterior body that was decorated to differentiate the product for each product. The payout mechanism of the payout structure covers most of the payout structure and, when attached to the exterior body, projects to the outside and can be decorated, and a connecting portion projects from the lower end of the sleeve and connects to the exterior body. Was operated by relative rotation.

  Since the connecting portion at the lower end is connected to the exterior body, the payout structure is easily swayed around the connecting portion at the lower end. When the feeding structure is shaken sideways, the deflection width of the leading end of the feeding structure is large, the sleeve outer wall is at the uppermost end of the exterior body, and has a fitting portion that fits the cap in a removable manner. It hits the upper end of the inner wall of the fitting part.

  In Patent Literature 1, a coating film is provided on the inner surface of the fitting portion so that the outer wall of the sleeve is in contact with the coating film, and the rotation feeding operation can be smoothed. In Patent Document 2, a plurality of support protrusions are provided on the inner peripheral surface of the fitting portion to regulate the lateral swing of the feeding structure. In Patent Document 3, an abutting portion with which the sleeve side surface abuts is provided at a position slightly lower than the inner peripheral surface and the mouth of the fitting portion, thereby preventing the occurrence of scratches at positions visible from the outside of the sleeve side surface.

  The above-mentioned patent documents have the effects of smoothing the rotation operation, regulating the lateral shake, and preventing the occurrence of scratches due to the lateral shake. However, due to the structure that holds the end of the payout structure, it is difficult to prevent the occurrence of lateral vibration itself. A rattling sound that occurs when they hit each other has occurred. This rattling sound detracted from the luxury of cosmetic containers.

  In order to solve the above-described problems, the present invention includes a sleeve 3 that holds the bar-shaped cosmetic 1 and that includes a feeding mechanism 10 that slides the bar-shaped cosmetic 1 up and down, and covers almost the whole except the upper and lower ends. A feeding structure A that drives the feeding mechanism 10 by relatively rotating the connecting portion 41 protruding from the lower end of the sleeve 3, a cap (not shown), and a fitting portion 51 in which the cap is detachably fitted. The outer cylinder B and the main body cylinder 9 to which the intermediate cylinder 5 is secured, and the sleeve 3 of the extension structure A passing through the intermediate cylinder 5 of the outer casing B. In the configuration in which the connecting portion 41 of the body A and the outer body B are fixed and the outer body B and the feeding structure A are connected, the deformable and the sleeve 3 passes between the middle cylinder 5 and the main body cylinder 9. The contact tube 6 is clamped. A contact portion 60 having an inner diameter α equal to or slightly smaller than the sleeve outer diameter β is provided on the inner wall of the contact cylinder 6. By this contact portion 60, the feeding structure A is supported on the shaft center 15 of the exterior body B with a certain degree of elasticity. The projecting portion 60 has a shape in which sliding resistance is unlikely to occur when the sleeve 3 and the outer package B are relatively rotated.

  Specifically, the contact portion 60 has a deformable bellows shape with a sharpened tip 61, and the inner diameter is narrowed by being sandwiched between the middle cylinder 5 and the main body cylinder 9, and the outer wall of the sleeve 3. Line contact or point contact.

  In the present invention, as described above, the feeding structure A is supported on the shaft center 15 of the exterior body B by the abutting portion 60 of the abutting cylinder 6, so that the outer wall of the sleeve 3 does not hit any other place and makes a rattling sound. There is nothing. Further, since the tip 61 of the contact portion 60 is in line contact or point contact with the outer wall of the sleeve 3, sliding resistance during relative rotation hardly occurs, and the operational feeling of the container is not affected.

  Further, the contact tube 6 is provided with a deformable bellows-shaped contact portion 60, and when the contact tube 6 is sandwiched between the middle tube 5 and the main body tube 9, the inner diameter of the contact portion 60 is reduced. It is like. Therefore, when the contact cylinder 6 is a single body, that is, when no load is applied from above and below, the inner diameter α2 of the contact portion 60 is slightly larger than the outer diameter β of the sleeve 3 so that the sleeve 3 can be inserted easily. When the middle cylinder 5, the contact cylinder 6 and the main body cylinder 9 are assembled, the inner diameter α of the contact portion 60 is narrowed, and becomes the same diameter as the outer diameter β of the sleeve 3 or slightly smaller. The shaft 15 is supported.

  First, as a mode for carrying out the present invention, a bar-shaped cosmetic material feeding container composed of a feeding structure A in which a feeding mechanism 10 is arranged below the bar-shaped cosmetic material 1 will be described with reference to FIGS.

  A red plate 2 that holds the lower end of a stick-shaped cosmetic 1 such as a lipstick or a stick foundation has a leg tube 20 depending on the lower end. The leg tube 20 has a guide protrusion 21 protruding from the lower outer wall. Further, a pair of notches 22 are provided from the lower end of the leg cylinder 20 so that the leg cylinder 20 provided with the guide protrusion 21 can be narrowed inward. Further, a female screw 23 is screwed on the lower inner surface of the leg tube 20. The red plate 2 is housed in the sleeve 3 so as to be slidable up and down.

  The sleeve 3 is a thin metal pipe and is decorated to differentiate the product. A guide groove 30 is formed in the lower side surface of the sleeve 3 in parallel with the axis. The guide groove 30 engages with the guide projection 21 of the red plate 2 to guide the red plate 2 so that it cannot slide. Further, the stroke (sliding length) of the red plate 2 is determined by the length of the guide groove 30. The leg tube 20 of the red plate 2 is inserted into the guide groove 30 with the guide tube 21 being inwardly narrowed, and the guide protrusion 21 is engaged. A screw cylinder 4 is inserted into the lower end of the sleeve 3.

  The screw cylinder 4 includes a screw portion 40 that enters the leg tube 20 of the red plate 2 and a connecting portion 41 that protrudes from the rear end of the sleeve 3. On the outer wall of the screw portion 40, a male screw 42 that is screwed with the female screw 23 provided on the leg tube 20 of the red plate 2 is screwed. The connecting portion 41 includes an upper connecting portion 43 into which the rear end portion of the sleeve 3 is fitted and a lower connecting portion 44 that protrudes outward from the lower end of the sleeve 3.

  Two circumferential grooves (a first circumferential groove 45 and a second circumferential groove 46) are formed on the outer wall of the upper connection portion 43. The inner circumferential rib 31 of the sleeve 3 is rotatably engaged with the first circumferential groove 45 so as not to fall off. The inner peripheral rib 31 is formed from the outside of the sleeve 3 toward the inner peripheral direction. The O-ring 11 is fitted in the second circumferential groove 46. The O-ring 11 is made of an elastic material such as NBR, and is in sliding contact with the inner wall of the sleeve 3 with elasticity. A groove-like engaging portion 47 is provided around the outer peripheral wall of the lower connecting portion 44, and a number of vertical grooves 48 are formed on the entire side of the lower side wall of the engaging portion 47 in parallel with the axis. Yes.

  A feeding structure A is constituted by the red plate 2, the sleeve 3 and the screw cylinder 4. In the feeding structure A, when the sleeve 3 and the screw cylinder 4 are rotated relative to each other, the female screw 23 in the leg cylinder 20 of the red platen 2 blocked by the guide groove 30 of the sleeve 3 is connected to the male screw of the screw cylinder 4. Since it is screwed with 42, it has the feeding mechanism 10 in which the red plate 2 moves forward and backward by screwing action. When the sleeve 3 and the screw cylinder 4 are rotated relative to each other, the O-ring 11 in the second circumferential groove 46 of the screw cylinder 4 is in contact with the inner wall of the sleeve 3 with elasticity, so that sliding resistance is generated. This sliding resistance produces a good feeling of rotational operation.

  The feeding structure A is attached to the exterior body B. The exterior body B is composed of a cap (not shown), a middle cylinder 5 and a main body cylinder 9, and the exposed portion is decorated to differentiate the product. The middle cylinder 5 is fastened to the upper end of the main body cylinder 9, and the upper part projects upward from the main body cylinder 9 to form a fitting portion 51 into which the cap is detachably fitted. The inner wall of the middle cylinder 5 is provided with an upper contact portion 56 having a large diameter on the lower side. Further, a lower abutting portion 90 whose upper diameter is larger is provided on the upper inner wall of the main body cylinder 9, and a recess is formed between the upper abutting portion 56 of the middle cylinder 5 and the lower abutting portion 90 of the main body cylinder 9. 53 is formed. Furthermore, a structure holding portion 91 that engages and holds the connecting portion 41 of the feeding structure A is provided on the lower inner wall of the main body cylinder 9.

  On the inner wall of the structure holding portion 91 of the main body cylinder 9, a retaining projection 92 and a rotation preventing projection 93 are projected. The retaining protrusion 92 engages with a groove-like engaging portion 47 provided on the connecting portion 41 of the feeding structure A to hold the feeding structure A so that it cannot fall off. Further, the anti-rotation protrusion 93 engages with the vertical groove 48 provided in the connecting portion 41 of the feeding structure A to hold the screw cylinder 4 of the feeding structure A in a non-rotatable manner.

  A contact cylinder 6 is housed in a recess 53 formed by the middle cylinder 5 and the main body cylinder 9 (see FIG. 4). A thin portion 64 is provided on the side wall of the contact cylinder 6, and the thin portion 64 is protruded inward in a square shape to constitute a bellows-shaped contact portion 60. The contact portion 60 is deformable with a certain degree of elasticity, and the inner diameter α2 of the contact portion 60 is the outer diameter of the sleeve 3 in an unloaded state (the state of the contact tube 6 alone, see FIG. 9). The diameter is slightly larger than β, and there is no problem in inserting the sleeve 3 during assembly. However, when the contact cylinder 6 is mounted in the recess 53 and sandwiched between the middle cylinder 5 and the main body cylinder 9, the contact portion 60 is narrowed as shown in FIG. α is equal to or slightly smaller than the outer diameter β of the sleeve 3, and the sleeve 3 is supported on the shaft 15 with a certain degree of elasticity.

  Furthermore, as another embodiment of the present invention, a bar-shaped cosmetic material supply container composed of a supply structure A in which the supply mechanism 10 is arranged around the bar-shaped cosmetic material 1 will be described with reference to FIGS.

  A red plate 2 that holds the lower end of a stick-shaped cosmetic 1 such as a lipstick or a stick foundation has a pair of threaded projections 24 protruding from the outer wall. The red plate 2 is housed inside the body cylinder 7 so as to be slidable up and down.

  A spiral holding portion 71 is provided on the outer wall of the storage portion 70 that stores the stick-shaped cosmetic 1 and the red plate 2 of the body tube 7. A pair of guide grooves 30 are formed in the side wall of the spiral holding portion 71 in parallel with the axis. The guide groove 30 guides the red plate 2 so as to be non-rotatably slidable through the threaded projection 24 of the red plate 2. Further, the stroke (sliding length) of the red plate 2 is determined by the length of the guide groove 30. A connecting portion 41 is provided below the storage portion 70 of the cylinder 7. Further, the helical cylinder 71 holds the helical cylinder 8 in a rotatable manner so as not to fall off.

  A helical groove 80 is screwed on the inner wall of the helical cylinder 8 to which the screwing projection 24 of the red plate 2 passing through the guide groove 30 of the body cylinder 7 is screwed. An outer peripheral knurl 81 parallel to the axis is engraved on the lower outer periphery of the helical cylinder 8. The helical cylinder 8 and the body cylinder 7 are inserted into the sleeve 3.

  The sleeve 3 is decorated to differentiate the product, and an inner peripheral knurl 32 that holds the helical cylinder 8 in an unrotatable manner by engaging the outer peripheral knurl 81 of the helical cylinder 8 on the inner wall. Has been established. By this inner peripheral knurl 32, the helical cylinder 8 is driven as the sleeve 3 rotates. The connecting portion 41 of the body cylinder 7 includes an upper connecting portion 43 into which the rear end portion of the sleeve 3 is fitted and a lower connecting portion 44 that protrudes outward from the rear end of the sleeve 3.

  Two circumferential grooves (a first circumferential groove 45 and a second circumferential groove 46) are formed on the outer wall of the upper connection portion 43. The O-ring 11 is fitted in the first circumferential groove 45. The O-ring 11 is made of an elastic material such as NBR, and is in sliding contact with the inner wall of the sleeve 3 with elasticity. The inner circumferential rib 31 of the sleeve 3 is rotatably engaged with the second circumferential groove 46 so as not to fall off. The inner peripheral rib 31 is formed from the outside of the sleeve 3 toward the inner peripheral direction. A groove-like engaging portion 47 is provided around the outer peripheral wall of the lower connecting portion 44, and a number of vertical grooves 48 are formed on the entire side of the lower side wall of the engaging portion 47 in parallel with the axis. Yes.

  A feeding structure A is constituted by the red plate 2, the sleeve 3, the body cylinder 7, and the helical cylinder 8. In the feeding structure A, when the sleeve 3 and the body cylinder 7 are rotated relative to each other, the screw protrusion 24 of the red plate 2 whose rotation is prevented by the guide groove 30 of the body cylinder 7 follows the sleeve 3. Since it is screwed into the helical groove 80, it has a feeding mechanism 10 in which the red pan 2 moves forward and backward by screwing action. When the sleeve 3 and the cylinder 7 are rotated relative to each other, the O-ring 11 in the first circumferential groove 46 of the cylinder 7 is in contact with the inner wall of the sleeve 3 with elasticity, so that sliding resistance is generated. This sliding resistance produces a good feeling of rotational operation.

  The feeding structure A is attached to the exterior body B. The exterior body B is composed of a cap (not shown), a middle cylinder 5 and a main body cylinder 9, and the exposed portion is decorated to differentiate the product. The middle cylinder 5 is fastened to the upper end of the main body cylinder 9, and the upper part protrudes from the main body cylinder 9 and is a fitting portion 51 into which the cap is detachably fitted. The inner wall of the middle cylinder 5 is provided with an upper contact portion 56 having a large diameter on the lower side. Further, a lower abutting portion 90 whose upper diameter is larger is provided on the upper inner wall of the main body cylinder 9, and a recess is formed between the upper abutting portion 56 of the middle cylinder 5 and the lower abutting portion 90 of the main body cylinder 9. 53 is formed. A structure holding portion 91 that engages and holds the connecting portion 41 of the feeding structure A is provided on the lower inner wall of the main body cylinder 9.

  On the inner wall of the structure holding portion 91 of the main body cylinder 9, a retaining projection 92 and a rotation preventing projection 93 are projected. The retaining protrusion 92 engages with a groove-like engaging portion 47 provided on the connecting portion 41 of the feeding structure A to hold the feeding structure A so that it cannot fall off. Further, the anti-rotation protrusion 93 engages with the vertical groove 48 provided in the connecting portion 41 of the feeding structure A to hold the screw cylinder 4 of the feeding structure A in a non-rotatable manner.

  A contact cylinder 6 is housed in a recess 53 constituted by the middle cylinder 5 and the main body cylinder 9 (see FIG. 8). A thin portion 64 is provided on the side wall of the contact cylinder 6, and the thin portion 64 is protruded inward in a square shape to constitute a bellows-shaped contact portion 60. The contact portion 60 is deformable with a certain degree of elasticity, and the inner diameter α2 of the contact portion 60 is the outer diameter of the sleeve 3 in an unloaded state (the state of the contact tube 6 alone, see FIG. 9). The diameter is slightly larger than β, and there is no problem in inserting the sleeve 3 during assembly. However, when the contact tube 6 is mounted in the recess 53 and the contact tube 6 is sandwiched between the middle tube 5 and the body tube 9, the contact portion 60 is narrowed as shown in FIG. α is equal to or slightly smaller than the outer diameter β of the sleeve 3, and the sleeve 3 is supported on the shaft 15 with a certain degree of elasticity. The contact portion 60 has a pointed tip 61 as shown in FIG. 10 and is brought into line contact with the outer wall of the sleeve 3 so that sliding resistance is unlikely to occur between the outer wall and the sleeve 3. It does not affect the feeling of operation.

  In the case of carrying out the present invention, the stick-shaped cosmetic material delivery container is almost entirely covered by the sleeve 3 except for the upper end where the stick-shaped cosmetic material 1 appears and disappears and the lower end from which the connecting portion 41 protrudes. The connecting portion 41 of the feeding structure portion A having the feeding mechanism 10 that is driven is connected to the exterior body B, and the abutting tube 6 is in contact with the inner wall between the middle cylinder 5 and the body cylinder 9 of the exterior body B. This can be implemented if the recess 53 that can be held is held at a position facing the sleeve 3 of the feeding structure A. Accordingly, the feeding mechanism 10 in the feeding structure portion A can be freely selected as long as the above-described conditions are satisfied, and a weighting mechanism such as an accompanying O-ring 11 can be freely set. Furthermore, in the case of the configuration of the second embodiment, it is possible to integrate components such as integrally forming the sleeve 3 and the helical cylinder 8.

  In the column of the embodiment, the connection between the feeding structure A and the exterior body B is described by the engagement of the engagement portion 47 and the retaining protrusion 92 and the engagement of the longitudinal groove 48 and the rotation prevention protrusion 93. However, not only the connection method by these engagements but also a method of directly fixing the feeding structure A and the exterior body B such as caulking and bonding can be performed.

  When the feeding structure A and the exterior body B are connected by engagement such as the engagement of the engaging portion 47 and the retaining protrusion 92 and the engagement of the vertical groove 48 and the non-rotating protrusion 93, they can be removed. By engaging and holding, the feeding structure A can be used as a cartridge-type bar-shaped cosmetic material feeding container that can be removed arbitrarily.

  The abutting cylinder 6 is sandwiched between the middle cylinder 5 and the main body cylinder 9 so that the abutting portion 60 is deformed and the inner diameter is reduced, and the sleeve 3 of the feeding structure A is supported by the shaft 15. Even if the entire contact tube 6 is formed of an elastically deformable material such as NBR or elastomer resin, the contact portion can be formed into a thin bellows shape and deformed only to the contact portion 60 as shown in FIG. It may be configured. Note that this elasticity may be a minimum elasticity necessary for supporting the feeding structure A on the shaft center 15, and does not necessarily need to have resilience.

  The contact portion 60 of the contact tube 6 has a bellows shape as shown in FIG. 9, but as shown in FIG. 10, the contact portion 60 is easily deformed by providing a notch 65 in the contact portion 60. You may do it. In this case, the outer wall of the sleeve 3 is intermittently brought into line contact. However, if the notches 65 are evenly arranged, the sleeve 3 can be held on the shaft 15 without any problem. In addition, the operation feeling is not adversely affected.
