Description

Technical Field

[0001] The present invention relates to a cartridge-type stick cosmetic dispensing container in which stick cosmetics such as lipsticks, lip liners, and lip creams can be replaced, the cartridge thereof, and a cartridge case.

Background Art

[0002] Conventionally, a middle plate that stores stick cosmetics such as lipsticks, lip liners, and lip creams and slides up and down by a feeding mechanism in a stick cosmetic dispensing container has been divided into a fitting cylinder that holds the stick cosmetic and a holding cylinder that slides up and down by the feeding mechanism, and a so-called double middle plate type container in which the holding cylinder and the fitting cylinder are detachably connected is known. As described in Patent Document 1, this double middle plate type container can be a cartridge-type stick cosmetic dispensing container in which the stick cosmetic and the fitting cylinder can be replaced as a cartridge.

[0003] The stick cosmetic and the fitting cylinder were stored separately from the container, and the fitting cylinder was set in the container body as needed to complete the stick cosmetic dispensing container. Also, when the stick cosmetic and the fitting cylinder were used as a cartridge, the cartridge was stored in the cartridge case so as not to stain other places with the stick cosmetic and not to damage the stick cosmetic. Moreover, using this cartridge case, the cartridge could be attached without touching the stick cosmetic.

[0004] Since the stick cosmetic and the fitting cylinder were stored individually, they were smaller than when stored in a container, and it was possible to reduce the inventory storage space. When the stick cosmetic was defective or when the stick cosmetic was used up, only the fitting cylinder needed to be discarded, and it was possible to reduce waste and waste disposal costs. Also, when the fitting cylinder was made into a cartridge, the container could be used repeatedly by replacing it with a new cartridge.

[0005] On the other hand, in addition to the configuration shown in Patent Document 1, in which the dispensing mechanism for dispensing the stick-shaped cosmetic is arranged around the stick-shaped cosmetic, there is also a known configuration shown in Patent Document 2, in which the dispensing mechanism for dispensing the stick-shaped cosmetic is arranged below the stick-shaped cosmetic. The container with the configuration shown in Patent Document 2 was able to have a smaller outer diameter compared to the container with the configuration shown in Patent Document 1. Furthermore, the container with the configuration shown in Patent Document 2 is suitable for storing the soft and easily broken stick-shaped cosmetic that is commonly used in recent years, as it directly houses the stick-shaped cosmetic within the pipe-shaped sleeve of the container. The tip of this sleeve and the tip of the stick-shaped cosmetic were often cut at an angle to facilitate application of the stick-shaped cosmetic. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Utility Model Publication No. 61-154819 [Patent Document 2] Japanese Patent Application Publication No. 6-181813 [Overview of the project] [Problems that the invention aims to solve]

[0007] In the container shown in Patent Document 2, where the dispensing mechanism is located below the stick-shaped cosmetic, the stick-shaped cosmetic is directly housed in a pipe-shaped sleeve. This minimizes the clearance between the sleeve and the stick-shaped cosmetic, holding the soft stick-shaped cosmetic against the inner wall of the sleeve and making it less likely to break. On the other hand, when cartridgeizing the stick-shaped cosmetic and the receptacle using a double-dish system, it is preferable to have a larger clearance between the sleeve's housing area and the stick-shaped cosmetic to prevent damage to the stick-shaped cosmetic when inserting and removing the stick-shaped cosmetic and receptacle. In other words, repurposing the inner dish of the double-dish system shown in Patent Document 1 for the stick-shaped cosmetic dispensing container shown in Patent Document 2 presented difficulties in balancing the protection of the stick-shaped cosmetic with the ease of cartridge installation. The present invention aims to provide a cartridge-type retractable container for retractable [Means for solving the problem]

[0008] Container B has a dispensing mechanism B' positioned below the stick-shaped cosmetic product 1 housed in the sleeve 4, which slides the stick-shaped cosmetic product 1 up and down. A holding tray 2 for holding the stick-shaped cosmetic product 1 is detachably attached to a receiving tray 3 that slides up and down by the dispensing mechanism B' of container B, thereby forming a cartridge-type stick-shaped cosmetic product dispensing container with the stick-shaped cosmetic product 1 and the holding tray 2 as cartridge A. The outer diameters of the receiving tray 3 and the holding tray 2 are slightly smaller than the inner diameter of the sleeve 4. A pair of gripping claws 314 and 316 are erected on the upper surface of the receiving tray 3, and the side surface of the holding tray 2 is provided with fitting portions 22 and 23 that fit between and engage with the gripping claws 314 and 316 of the receiving tray 3, thereby integrally connecting the holding tray 2 and the receiving tray 3. When the red pigment tray 3 is at its upper limit, the gripping claws 314 and 316 of the red pigment tray 3 protrude from the tip of the sleeve 4, making the gripping claws 314 and 316 deformable, enabling the gripping claws 314 and 316 to engage with, overcome over, and disengage from the fitting portions 22 and 23 of the red pigment tray 3. Furthermore, when the red pigment tray 3 is inside the sleeve 4, the sleeve 4 prevents the gripping claws 314 and 316 from deforming, thus preventing the gripping claws 314 and 316 from disengaging from the fitting portions 22 and 23 of the red pigment tray 3.

[0009] This cartridge A is housed in a cartridge case A' consisting of a temporary cap 10 and a rouge holder 9. A pair of retaining recesses 24 are engraved on the side walls of cartridge A, excluding the insertion portions 22 and 23 of the retaining rouge 2. The lower part of the rouge holder 9 of this cartridge case A' is an insertion portion 91 into which the tip of the sleeve 4 of container B is fitted so as to be able to slide up and down. The upper part of the rouge holder 9 is a housing portion 92 that houses the retaining rouge 2. A pair of outwardly deformable engaging pieces 93 are notched and molded on the side wall of this insertion portion 91. A retaining engaging portion 931 is provided projecting from the inner wall of the tip of this engaging piece 93, which engages with the retaining recesses 24 of the retaining rouge 2 to hold the retaining rouge 2 inside the rouge holder 9. The lower part of this retaining engaging portion 931 is molded into a slanted cam surface 932. The temporary cap 10 of cartridge case A' covers the rod-shaped cosmetic 1 of cartridge A. When the red dye tray holder 9 is fitted onto the tip of the sleeve 4, the retaining red dye tray 2 and the receiving tray 3 inside the red dye tray holder 9 engage together. The sliding of the red dye tray holder 9 causes the position of the retaining engagement portion 931 relative to the retaining red dye tray 2 to move. The cam surface 932 of this retaining engagement portion 931 causes the retaining engagement portion 931 to disengage from the retaining recess 24, come into contact with the tip of the sleeve 4, and push the engaging piece 93 outward, releasing the engagement between the retaining red dye tray 2 and the red dye tray holder 9, so that the engagement of cartridge A shifts from cartridge case A' to container B. [Effects of the Invention]

[0010] As described above, the present invention implements a cartridge mechanism utilizing a double inner tray system for a stick-shaped cosmetic dispensing container B, in which the dispensing mechanism B' is positioned below the stick-shaped cosmetic 1. In order to achieve the conflicting objectives of ease of insertion and removal of cartridge A and protection of the stick-shaped cosmetic 1, the replacement position of cartridge A is set so that the gripping claws 314 and 316 of the receiving tray 3 protrude beyond the tip of the sleeve 4, thereby making it easier to insert and remove cartridge A. At the same time, since cartridge A is inserted and removed at a position that protrudes beyond the sleeve 4 and is independent of the sleeve 4, damage to the stick-shaped cosmetic 1 by the sleeve 4 can be prevented. Therefore, it is not necessary to have a large clearance between the sleeve 4 and the stick-shaped cosmetic 1 for the insertion and removal of cartridge A, and the clearance can be set to be the same as the optimal clearance for a stick-shaped cosmetic dispensing container in which the dispensing mechanism B' is positioned below the stick-shaped cosmetic 1. This allows the rod-shaped cosmetic product 1 to be protected by the sleeve 4, enabling the storage of soft rod-shaped cosmetic products 1, and allowing even soft, break-resistant rod-shaped cosmetic products to be packaged in cartridges.

[0011] Cartridge A has a temporary cap 10 covering the stick-shaped cosmetic 1, a retaining rouge tray 2 engaged and connected within a rouge tray holder 9, and is housed in cartridge case A', not exposed to the outside. To attach cartridge A to container B, the rouge tray holder 9 of cartridge case A' is fitted onto the tip of the sleeve 4 of container B, engaging and connecting the retaining rouge tray 2 and receiving rouge tray 3 of cartridge A. Then, when the rouge tray holder 9 is pushed down, the engagement between the retaining rouge tray 2 and the rouge tray holder 9 is released, and the retention of the retaining rouge tray 2 is transferred from the rouge tray holder 9 to container B. In other words, even in a cartridge-type stick-shaped cosmetic dispenser container where a cartridge mechanism using a double inner tray system is implemented in container B with a dispensing mechanism B' positioned below the stick-shaped cosmetic 1, the attachment of the retaining rouge tray 2 to container B is performed via the rouge tray holder 9 of cartridge case A', allowing for hygienic attachment of the retaining rouge tray 2 without directly touching the retaining rouge tray 2 or the stick-shaped cosmetic 1.

Mode for Carrying Out the Invention

[0013] Below the rod-shaped cosmetic 1 accommodated in the sleeve 4, a feeding mechanism B' for vertically sliding the rod-shaped cosmetic 1 is arranged in the container B. A holding plate 2 for holding the rod-shaped cosmetic 1 is detachably attached to a receiving plate 3 that vertically slides by the feeding mechanism B' of this container B, and a cartridge-type rod-shaped cosmetic dispensing container is formed with the rod-shaped cosmetic 1 and the holding plate 2 as a cartridge A. The outer diameters of the receiving plate 3 and the holding plate 2 are slightly smaller than the inner diameter of the sleeve 4. A pair of gripping claws 314 and 316 are erected on the upper surface of the receiving plate 3, and on the side surface of the holding plate 2, fitting portions 22 and 23 that can be fitted between and overcome the gripping claws 314 and 316 of the receiving plate 3 to integrally connect the holding plate 2 and the receiving plate 3 are provided. When the receiving plate 3 reaches the upper limit, the gripping claws 314 and 316 of the receiving plate 3 protrude from the tip of the sleeve 4 and the gripping claws 314 and 316 can be deformed, and the gripping claws 314 and 316 are configured to enable fitting, overcoming engagement, and disengagement with the fitting portions 22 and 23 of the receiving plate 3. Further, when the receiving plate 3 is inside the sleeve 4, the sleeve 4 is configured to make the gripping claws 314 and 316 unable to deform and prevent disengagement between the gripping claws 314 and 316 and the fitting portions 22 and 23 of the receiving plate 3.

[0014] The cartridge A is housed in a cartridge case A' composed of a temporary cap 10 and a red plate holder 9. A pair of holding recesses 24 are engraved on the side walls of the cartridge A other than the fitting portions 22 and 23 of the holding red plate 2. The lower part of the red plate holder 9 of the cartridge case A' is an insertion portion 91 into which the tip of the sleeve 4 of the container B is fitted so as to be vertically slidable. The upper part of the red plate holder 9 is a housing portion 92 for housing the holding red plate 2. A pair of engaging pieces 93 that can be deformed outward are notch-formed on the side wall of the insertion portion 91. A holding engaging portion 931 that engages with the holding recess 24 of the holding red plate 2 and holds the holding red plate 2 in the red plate holder 9 is protrudingly provided on the inner side wall of the tip of the engaging piece 93. The lower part of the holding engaging portion 931 is formed into an inclined cam surface 932. The temporary cap 10 of the cartridge case A' covers the rod-shaped cosmetic 1 of the cartridge A. When the red plate holder 9 is fitted to the tip of the sleeve 4, the holding red plate 2 in the red plate holder 9 and the receiving middle plate 3 are integrally engaged. Due to the sliding of the red plate holder 9, the position of the holding engaging portion 931 with respect to the holding red plate 2 moves, and the holding engaging portion 931 is disengaged from the holding recess 24 by the cam surface 932 of the holding engaging portion 931, abuts against the tip of the sleeve 4, and presses the engaging piece 93 outward, releasing the engaging hold between the holding red plate 2 and the red plate holder 9, and configuring the engaging hold of the cartridge A to shift from the cartridge case A' to the container B.

[0015] The tip of the sleeve 4 of the container B is a diagonally cut portion 43, and the tip of the rod-shaped cosmetic 1 of the cartridge A also has a diagonally cut tip shape that follows the cut portion 43 of the sleeve 4. The inner wall of the sleeve 4 is provided with a guide groove 421 that is long in the axial direction, and a guide projection 311 that protrudes from the receiving rouge tray 3 is engaged with this guide groove 421. This engagement guides the receiving rouge tray 3 to slide freely up and down within the sleeve 4 but not to rotate, and positions the receiving rouge tray 3 and the sleeve 4 at a predetermined angular position in the circumferential direction. A guide boss 313 is provided on the upper surface of the receiving rouge tray 3. The lower surface of the holding rouge tray 2 of the cartridge A is provided with a guide cylinder portion 21 that fits non-rotatably onto the guide boss 313 of the receiving rouge tray 3. The engagement of the guide boss 313 and the guide cylinder portion 21 guides the gripping claws 314 and 316 of the receiving rouge tray 3 into the fitting portions 22 and 23 of the holding rouge tray 2, while simultaneously positioning the holding rouge tray 2 and the receiving rouge tray 3 at a predetermined angular position in the circumferential direction. The engagement of the holding recess 24 of the holding rouge tray 2 of cartridge A and the holding engagement portion 931 of the rouge tray holder 9 of cartridge case A' houses and holds the holding rouge tray 2 within the rouge tray holder 9, while simultaneously positioning the rouge tray holder 9 and the holding rouge tray 2 at a predetermined angular position in the circumferential direction. An alignment rib 94 is provided protruding from the outer wall of the rouge tray holder 9 of cartridge case A', and the alignment rib 94 serves as a positioning guide at a predetermined angular position in the circumferential direction to mount the rod-shaped cosmetic product 1 of cartridge A onto the holding rouge tray 2 inside the rouge tray holder 9.

[0016] The cartridge A and container B are aligned at predetermined angles in the circumferential direction by the following actions: alignment and engagement of the lipstick holder 9 of cartridge case A' and the holding lipstick tray 2 of cartridge A at predetermined angles in the circumferential direction; alignment and mounting of the rod-shaped cosmetic 1 of cartridge A and the holding lipstick tray 2 of cartridge A at predetermined angles in the circumferential direction; alignment and engagement of the holding lipstick tray 2 of cartridge A and the receiving lipstick tray 3 of container B at predetermined angles in the circumferential direction; and alignment and engagement of the receiving lipstick tray 3 of container B and the sleeve 4 at predetermined angles in the circumferential direction. This ensures that when cartridge A is mounted in container B, the oblique inclination of the tip of the rod-shaped cosmetic 1 and the inclination of the cut portion 43 at the tip of sleeve 4 coincide.

[0017] In a cartridge-type retractable container for a stick-shaped cosmetic product, where a retraction mechanism B' is positioned below the stick-shaped cosmetic product 1, if the tip of the sleeve 4 is cut at an angle, the tip of the stick-shaped cosmetic product 1 to be installed as cartridge A must be aligned with the sleeve 4. Between the tip of the stick-shaped cosmetic product 1 of cartridge A and the tip of the sleeve 4 of container B, there is only one point of alignment around the entire circumference, and some kind of 1 / 360° alignment means is required when installing cartridge A into container B. In the present invention, the sleeve 4 of container B and the receiving rouge tray 3, the receiving rouge tray 3 and the holding rouge tray 2 for cartridge A, the holding rouge tray 2 and the rouge tray holder 9, and the rouge tray holder 9 and the stick-shaped cosmetic product 1 are aligned and engaged at predetermined angular positions in the circumferential direction. These are the main components of the cartridge-type stick-shaped cosmetic dispensing container B and cartridge A of the present invention. Since all of these main components are aligned and joined at predetermined angular positions in the circumferential direction, when the stick-shaped cosmetic 1 is attached to the holding tray 2 using the alignment rib 94 of the rouge tray holder 9 as a positioning guide at a predetermined angular position in the circumferential direction, the tip of the stick-shaped cosmetic 1 and the bevel of the cut portion 43 of the sleeve 4 automatically align. [Examples]

[0018] First, the cartridge-type retractable container and cartridge case of Embodiment 1 of the present invention will be described with reference to Figures 1 to 13. This cartridge-type retractable container and cartridge case consists of a cartridge A, a cartridge case A' that houses cartridge A, and a container B into which cartridge A is mounted. Container B has a retractable mechanism B' that slides the retractable cosmetic 1 up and down located below the storage space for the retractable cosmetic 1. By detachably engaging a holding tray 2 that holds the retractable cosmetic 1 with a receiving tray 3 that slides up and down by the retractable mechanism B', a cartridge A is created in which the retractable cosmetic 1 and the holding tray 2 can be replaced.

[0019] Container B consists of a red pigment tray 3, a sleeve 4, a base tube 5, a skirt tube 6, and a cap 7, as shown in Figures 1 and 3.

[0020] As shown in Figure 10, the red pigment tray 3 consists of a receiving cylinder 31 and a threaded rod 32 hanging down from the lower surface 312 of the receiving cylinder 31. Multiple guide protrusions 311 are projected from the outer peripheral wall of the receiving cylinder 31. These guide protrusions 311 are irregularly arranged on the outer circumference of the receiving cylinder 31. A guide boss 313 is projected from the upper surface of the receiving cylinder 31, offset to one side of the receiving cylinder 31. A first gripping claw 314 is erected on the upper surface of the guide boss 313, along the side of the receiving cylinder 31. A horizontally elongated first gripping protrusion 315 is projected from the inner wall of the tip of the first gripping claw 314. A second gripping claw 316 is erected on the upper surface of the receiving cylinder 31 opposite the first gripping claw 314, along the side. The tip of the second gripping claw 316 is at the same height as the tip of the first gripping claw 314. A second gripping projection 317 is provided on the inner wall of the tip of the second gripping claw 316, so as to face the first gripping projection 315 of the first gripping claw 314.

[0021] The threaded rod 32 is pipe-shaped, with male threads 321 screwed into its outer wall. Furthermore, the lower end side wall of the threaded rod 32 is provided with a pair of tongue-shaped stopper pieces 322, each notched in an inverted U-shape, allowing its upper end to bend inward. These stopper pieces 322 have a wedge shape, gradually protruding outward as they move upward, with their upper ends forming the widest outer diameter portion 323.

[0022] The base cylinder 5 is pipe-shaped with a through hole 51 drilled through it vertically. The threaded rod 32 of the red dye tray 3 is inserted into this through hole 51. The through hole 51 has an inner diameter that allows the threaded rod 32 to move up and down with some clearance. The upper part of the through hole 51 has a narrower inner diameter, and a female thread 512 that engages with the male thread 321 of the threaded rod 32 is threaded into the inner circumferential wall, forming a stepped portion 511 at the lower end. As shown in Figure 1, the lower surface 312 of the red dye tray 3 abuts against the upper end of the base cylinder 5, setting a downward limit, and as shown in Figures 2 and 3, the maximum outer diameter portion 323 of the stopper piece 322 of the threaded rod 32 abuts against the stepped portion 511 in the through hole 51, setting an upward limit, thereby restricting the vertical sliding range of the red dye tray 3. Furthermore, the circumscribed circle diameter of the maximum outer diameter portion 323 of the stopper piece 322 of the threaded rod 32 should be at least larger than the inner diameter of the female thread 512 in the through hole 51, and preferably larger than the root diameter of the female thread 512.

[0023] Furthermore, the upper outer wall of the base cylinder 5 is an insertion portion 52 with a diameter approximately the same as the circumscribed diameter of the guide projection 311 of the receiving cylinder 31 of the red dye tray 3. The lower outer wall of the base cylinder 5 is a base portion 53 with an outer diameter larger than that of the insertion portion 52. A stepped portion 531 is formed at the joint between the insertion portion 52 and the base portion 53. A fitting groove 521 and an engagement groove 522 are engraved on the outer circumferential wall of the insertion portion 52, positioned vertically. An O-ring 8 made of an elastic material such as elastomer or NBR is fitted into the fitting groove 521.

[0024] The receiving cylinder 31 of the lipstick tray 3 and the insertion portion 52 of the base cylinder 5 are inserted from below the sleeve 4, and the lower end of the sleeve 4 abuts against the stepped portion 531 of the base cylinder 5. The portion of the sleeve 4 opposite the insertion portion 52 becomes a support portion 41, and the inner diameter of this support portion 41 is slightly larger than the outer diameter of the insertion portion 52 of the base cylinder 5. Above this support portion 41 is a storage portion 42 that houses the receiving cylinder 31 and cartridge A of the lipstick tray 3. The inner diameter of this storage portion 42 is slightly larger than the outer diameter of the receiving cylinder 31 of the lipstick tray 3. As a result, when the lipstick tray 3 is housed in the sleeve 4, the first gripping claws 314 and the second gripping claws 316 of the receiving cylinder 31 of the lipstick tray 3 are prevented from deforming in the outward direction. The outer diameter of the base portion 53 of the base cylinder 5 is approximately the same as the outer diameter of the sleeve 4.

[0025] An O-ring 8 fitted to the insertion portion 52 of the base cylinder 5 elastically contacts the inner circumferential wall of the support portion 41 of the sleeve 4. As a result, when the sleeve 4 and the base cylinder 5 are rotated relative to each other, sliding friction resistance is generated between the sleeve 4 and the base cylinder 5 by the O-ring 8, and this sliding friction resistance creates a good, weighty rotational feel. Furthermore, an engagement rib 411 is molded to protrude inward from the outside at a position opposite the engagement groove 522 of the insertion portion 52. The engagement rib 411 engages with the engagement groove 522, connecting the sleeve 4 and the base cylinder 5 so that they can rotate freely and cannot be detached.

[0026] Furthermore, as shown in Figure 10, the tip of the sleeve 4 is cut at an angle, forming a beveled section 43. On the inner wall of the storage section 42 of the sleeve 4, a guide groove 421 is carved in the axial direction, which engages with the guide projection 311 of the receiving cylinder 31 of the receiving pan 3 to guide the receiving pan 3 so that it can slide up and down within the sleeve 4 but cannot rotate. This guide groove 421 corresponds to the guide projection 311 of the receiving pan 3, with the cut valley 431 of the beveled section 43 of the sleeve 4 facing the second gripping claw 316 of the receiving pan 3, and the cut peak 432 facing the first gripping claw 315.

[0027] The base 53 of the base cylinder 5 and the lower part of the sleeve 4 are inserted from above the skirt cylinder 6, with the upper part of the sleeve 4 protruding from the upper end of the skirt cylinder 6. The upper part of the skirt cylinder 6 is a fitting portion 62 into which the cap 7 is removably fitted. When the cap 7 is fitted into the fitting portion 62 of the skirt cylinder 6, it covers the upper part of the sleeve 4. The lower part of the skirt cylinder 6 is a fastening portion 61 that fastens the base 53 of the base cylinder 5.

[0028] Next, the dispensing mechanism B' inside container B will be explained with reference to Figures 1 to 3. The dispensing mechanism B' is constructed by engaging the guide projection 311 of the receiving rouge tray 3 with the guide groove 421 of the sleeve 4 so that it can slide up and down but not rotate, rotatably connecting the lower end of the sleeve 4 to the base cylinder 5, and screwing the male thread 321 of the receiving rouge tray 3 with the female thread 512 of the base cylinder 5. In the container B of Embodiment 1 of the present invention, the base cylinder 5 is fixed inside the skirt cylinder 6. Therefore, when the sleeve 4 and the skirt cylinder 6 are rotated relative to each other, the base cylinder 5 fixed inside the skirt cylinder 6 and the sleeve 4 also rotate relative to each other. Because the guide projection 311 of the receiving rouge tray 3 engages with the guide groove 421 of the sleeve 4, it moves with the sleeve 4, and because the male thread 321 of the receiving rouge tray 3 is screwed into the female thread 512 inside the base cylinder 5 which rotates relative to it, the receiving rouge tray 3 slides up and down inside the sleeve 4 due to the screw action. As shown in Figure 1, the lower surface 312 of the receiving cylinder 31 abuts against the upper end 524 of the insertion portion 52 of the base cylinder 5, setting the lower limit of the receiving tray 3. As shown in Figure 2, the stopper piece 322 of the threaded rod 32 abuts against the stepped portion 511 inside the through hole 51 of the base cylinder 5, setting the upper limit of the upward movement and restricting vertical sliding. When the receiving tray 3 is at its upper limit, as shown in Figure 3, the second gripping claw 316 on the upper surface of the receiving cylinder 31 protrudes above the cut valley portion 431 at the tip of the sleeve 4, allowing it to bend in the outer diameter direction, making it possible to attach and detach the holding tray 2 of the cartridge A.

[0029] Next, the assembly method for container B will be explained. When assembling the red pigment tray 3 and the base cylinder 5, the lower end of the threaded rod 32 of the red pigment tray 3 is inserted into the female thread 512 of the through hole 51 of the base cylinder 5. The stopper piece 322 of the threaded rod 32 is at least larger in diameter than the inner diameter of the female thread 512, but because it is wedge-shaped and can bend inward due to the notch, if it is forced in, it will be forced to narrow inward, pass through the female thread 512 and enter the through hole 51. When the stopper piece 322 reaches the through hole 51, the stopper piece 322 returns to its original position, and the upper end of the stopper piece 322 comes into contact with the stepped portion 511 of the female thread 512, making it impossible to disassemble again. The receiving cylinder 31 of the receiving tray 3 and the insertion portion 52 of the base cylinder 5 are inserted from the rear end of the sleeve 4, and the guide projection 311 of the receiving cylinder 31 of the receiving tray 3 is engaged with the guide groove 421 of the storage portion 42 of the sleeve 4, thereby connecting the receiving cylinder 31 so that it can slide up and down but cannot rotate. Due to this engagement between the guide projection 311 and the guide groove 421, as shown in Figure 10, the second gripping claw 316 of the receiving cylinder 31 is positioned at a circumferential angular position opposite the cutting valley 431 of the oblique cut portion 43 of the sleeve 4. In addition, the inner circumferential rib 411 of the support portion 41 of the sleeve 4 engages with the engagement groove 522 of the insertion portion 52 of the base cylinder 5, connecting the base cylinder 5 and the sleeve 4 so that they can rotate but cannot be detached. Furthermore, the base portion 53 of the base cylinder 5 that protrudes from the lower end of the sleeve 4 is inserted into the skirt cylinder 6 and fastened to the fastening portion 61 inside the skirt cylinder 6. Then, with the upper part of the sleeve 4 protruding from the fitting portion 62 of the skirt cylinder 6, the retraction mechanism B' and the skirt cylinder 6 are connected.

[0030] Furthermore, the inner circumferential rib 411 of the sleeve 4 may be formed either after the base cylinder 5 is assembled to the sleeve 4, or after the base cylinder 5 is assembled to the sleeve 4. If the base cylinder 5 is assembled after the inner circumferential rib 411 is formed, the sleeve 4 is formed on its own, which allows for a sharper shape of the inner circumferential rib 411. However, the base cylinder 5 will be forced into place due to the assembly after protruding molding. If the inner circumferential rib 411 is formed after assembly to the base cylinder 5, there is no impact on the base cylinder 5 during assembly. However, since the base cylinder 5 is the receiving mold during the formation of the inner circumferential rib 411, the shape of the inner circumferential rib 411 cannot be made sharp.

[0031] Next, Cartridge A of Embodiment 1 of the present invention and the cartridge case A' that houses Cartridge A will be described with reference to Figures 4 and 5. Cartridge A consists of a stick-shaped cosmetic liner 1 and a holding tray 2 that holds the end of the stick-shaped cosmetic liner 1.

[0032] As shown in Figure 11, the holding rouge tray 2 is cup-shaped and holds the lower end of the rod-shaped cosmetic 1, and has the same diameter as the receiving cylinder 31 of the receiving rouge tray 3 of the container B. A cylindrical guide cylinder portion 21 hangs down from the lower end of the holding rouge tray 2. The lower end of this guide cylinder portion 21 is notched to provide a notched engaging portion 211. When cartridge A is placed in container B, this guide cylinder portion 21 fits onto the guide boss 313 of the receiving cylinder 31, and the notched engaging portion 211 acts as a guide for positioning the holding rouge tray 2 and the receiving rouge tray 3 at a predetermined angular position in the circumferential direction.

[0033] Furthermore, as shown in Figure 12, a first fitting portion 22 and a second fitting portion 23 are engraved on the side surface of the holding red pigment tray 2. A first gripping recess 221 is provided on the upper side wall of the first fitting portion 22, and a second gripping recess 231 is provided on the upper side wall of the second fitting portion 23. When the holding red pigment tray 2 is connected to the receiving red pigment tray 3, the first fitting portion 22 and the second fitting portion 23 are fitted from above onto the first gripping claw 314 and the second gripping claw 316 of the receiving cylinder 31 of the receiving red pigment tray 3. At this time, as shown in Figures 1 and 2, the first gripping projection 315 of the first gripping claw 314 engages with the first gripping recess 221, and the second gripping projection 317 of the second gripping claw 316 engages with the second gripping claw 316. When the retaining red pigment tray 2 is fitted into the receiving red pigment tray 3, the retaining red pigment tray 2 and the receiving cylinder 31 of the receiving red pigment tray 3 become a single cylindrical body. In addition, a pair of retaining recesses 24 are engraved on the outer wall of the retaining red pigment tray 2 between the first fitting portion 22 and the second fitting portion 23.

[0034] As shown in Figure 13, cartridge case A' consists of a rouge holder 9 that holds the rouge tray 2 and a temporary cap 10 that covers the stick-shaped cosmetic 1, and houses cartridge A. As shown in Figure 12, the rouge holder 9 is a pipe-shaped structure that runs vertically through it. The lower part of the rouge holder 9 has an inner diameter slightly larger than the outer diameter of the sleeve 4, and is a fitting portion 91 into which the tip of the sleeve 4 can be inserted. The upper part of the rouge holder 9 has a housing portion 92 with an inner diameter slightly larger than the outer diameter of the rouge tray 2. This housing portion 92 faces the outer wall of the rouge tray 2 when the rouge tray 2 is housed in the rouge holder 9. A stepped contact portion 96 is provided at the joint between the fitting portion 91 and the housing portion 92 due to the difference in inner diameter.

[0035] As shown in Figure 12, the side wall of the insertion portion 91 of the red dye tray holder 9 is provided with a pair of engagement pieces 93 that are cut out in an inverted U-shape and can be deformed outward at symmetrical positions. The engagement pieces 93 have the same inner diameter as the insertion portion 91, but the upper inner wall of the engagement pieces 93 is a holding portion 97 that protrudes to the same diameter as the inner diameter of the housing portion 92. A holding engagement portion 931 is provided on the inner wall of this holding portion 97 that engages with the holding recess 24 of the holding red dye tray 2. The engagement of this holding recess 24 and the holding engagement portion 931 positions and holds the holding red dye tray 2 at a predetermined angular position in the circumferential direction within the red dye tray holder 9. The lower surface of this convex holding engagement portion 931 is a slanted cam surface 932, as shown in Figure 5. This cam surface 932 abuts against the lower side of the holding recess 24.

[0036] Furthermore, as shown in Figure 13, a single aligning rib 94 is provided projecting from the outer wall of the red dye tray holder 9, extending in the axial direction. This aligning rib 94 reaches the upper and lower ends of the red dye tray holder 9. In addition, a pair of notches are provided in the upper side wall of the red dye tray holder 9, extending axially from the upper end surface, with a deformable tongue-shaped connecting piece 95 provided between them. A pair of these connecting pieces 95 are arranged symmetrically, and engaging projections 951 are provided projecting from the upper outer wall. A temporary cap 10 is fitted onto the upper part of the red dye tray holder 9.

[0037] This temporary cap 10 is made of transparent synthetic resin, allowing the rod-shaped cosmetic product 1 of the contained cartridge A to be visible from the outside. The temporary cap 10 consists of a fitting portion 101 that fits onto the upper part of the rouge holder 9 and a covering portion 102 that covers the rod-shaped cosmetic product 1 of the contained cartridge A. The side wall of the fitting portion 101 is provided with an engagement window portion 104 that engages with the connecting projection 951 of the connecting piece 95 of the rouge holder 9, positioning the rouge holder 9 and the temporary cap 10 at a predetermined angular position in the circumferential direction. Furthermore, the side wall of the fitting portion 101 is engraved with an alignment slit 103 that engages with the alignment rib 94 of the rouge holder 9. As a result, the engagement between the alignment rib 94 of the rouge holder 9 and the alignment slit 103 of the temporary cap 10 acts as a positioning guide at a predetermined angular position in the circumferential direction, allowing the connecting projection 951 of the rouge holder 9 and the engagement window portion 104 of the temporary cap 10 to engage. Similarly, the alignment rib 94 of the red dye tray holder 9 can also serve as a positioning guide for the circumferential angle position of the stick-shaped cosmetic 1 when it is attached to the retaining red dye tray 2 which is engaged and held within the red dye tray holder 9. A certain amount of space 105 is provided between the ceiling of the cover portion 102 of the temporary cap 10 and the tip of the stick-shaped cosmetic 1.

[0038] Next, the method for attaching cartridge A to container B will be explained with reference to Figures 3, 6 to 9. As shown in Figure 3, container B is positioned by raising the red pigment tray 3 to its upper limit, causing the second gripping claw 316 of the receiving cylinder 31 to protrude above the cutting groove 431 of the cutting portion 43 of the sleeve 4, thus setting the position for attaching cartridge A.

[0039] As shown in Figure 6, the insertion portion 91 of the rouge holder 9 of cartridge A is inserted into the tip portion of the sleeve 4 of container B. At this time, as shown in Figure 11, the guide cylinder portion 21 of the retaining rouge 2 housed in the rouge holder 9 of cartridge A engages with the guide boss 313 of the receiving rouge 3 of container B, positioning the retaining rouge 2 at a predetermined angular position in the circumferential direction relative to the receiving rouge 3, and guiding it in a state where it cannot rotate. Then, the first gripping claw 314 is inserted into the first insertion portion 22 of the retaining rouge 2, and the second gripping claw 316 is inserted into the second insertion portion 23 of the retaining rouge 2. Since the second gripping claw 316 of the receiving rouge tray 3 protrudes upward from the cut valley 431 at the tip of the sleeve 4 and can bend outward, the first gripping projection 315 of the first gripping claw 314 and the second gripping projection 317 of the second gripping claw 316 overcome and engage with the first gripping recess 221 of the first fitting part 22 and the second gripping recess 231 of the second fitting part 23, respectively. As a result, the holding rouge tray 2 of cartridge A and the receiving cylinder 31 of the receiving rouge tray 3 are joined and connected in a single cylindrical shape without any protrusions or indentations.

[0040] With the holding tray 2 of cartridge A and the receiving tray 3 of container B connected and linked, if the cartridge case A' containing cartridge A is pushed down further, as shown in Figure 7, cartridge A will not move due to being connected and linked to the receiving tray 3 of container B, and only cartridge case A' will attempt to slide downward. At this time, the holding engagement portion 931 of the tray holder 9 of cartridge case A', which engages with the holding recess 24 of the holding tray 2 of cartridge A, will attempt to shift downward. In addition to this shifting stress, the cam surface 932 provided on the holding engagement portion 931 causes the engaging piece 93 of the tray holder 9 to bend outward, causing the holding engagement portion 931 to disengage from the holding recess 24, be pushed open, and come into contact with the outer wall of the holding tray 2. In the state shown in Figure 7, the engagement between the retaining recess 24 of cartridge A and the retaining engagement portion 931 of cartridge case A' is released, but the retaining engagement portion 931 of the engagement piece 93 of cartridge case A' elastically contacts the outer wall of the retaining tray 2 of cartridge A, so cartridge A is not completely detached from cartridge case A'.

[0041] As shown in Figure 8, as the downward pressure on cartridge case A' continues, the retaining engagement portion 931 of the engaging piece 93 of cartridge case A' moves downward while contacting the outer wall of the retaining pan 2 of cartridge A. When the cam surface 932 of this retaining engagement portion 931 contacts the tip of the sleeve 4 of container B, the action of the cam pushes the engaging piece 93 of the pan holder 9 further outward, causing the engaging piece 93 to bend outward. Then, the retaining engagement portion 931 of the engaging piece 93 contacts the outer wall of the sleeve 4, and the retention of the pan holder 9 of cartridge case A' and the retaining pan 2 of cartridge A is completely lost. The tip of the sleeve 4 contacts the contact portion 96 of the pan holder 9, preventing the pan holder 9 from descending, and informing the user that the downward pressure on cartridge case A' for inserting cartridge A into container B is complete.

[0042] In this state, as shown in Figure 9, when the container B is lowered, the retaining rouge tray 2, which is connected and engaged with the receiving rouge tray 3, detaches from the cartridge case A' and is housed in the sleeve 4 together with the rod-shaped cosmetic product 1 held in the retaining rouge tray 2. When the receiving rouge tray 3 is positioned inside the sleeve 4, the first gripping claws 314 and second gripping claws 316 of the receiving rouge tray 3 are positioned against the inner wall of the sleeve 4 on their backs, preventing outward deformation and holding the retaining rouge tray 2 in a way that prevents it from falling out. When the receiving rouge tray 3 is lowered to its lowest limit, the tip of the rod-shaped cosmetic product 1 held by the retaining rouge tray 2 is housed inside the sleeve 4. Then, the cartridge case A' is removed from the container B. When the cartridge case A' is removed, the engaging piece 93 of the rouge tray holder 9 returns to the engaged holding state of the retaining rouge tray 2 of cartridge A, but the holding engaging part 931 does not damage the rod-shaped cosmetic product 1. After removing this cartridge case A', the stick-type cosmetic product 1 can be used in the same way as a regular stick-type cosmetic product dispenser.

[0043] When the stick-shaped cosmetic 1 is used up, to remove the retaining rouge tray 2, as shown in Figure 2, the receiving rouge tray 3 is raised to its upper limit, causing the retaining rouge tray 2 to protrude from the tip of the sleeve 4, and the second gripping claw 316 of the receiving rouge tray 3 to protrude upward from the cut groove 431 of the sleeve 4. As a result, the second gripping claw 316 becomes able to bend outward, and the retaining rouge tray 2 can be removed by simply grasping it and pulling it upward to release the engagement between the retaining rouge tray 2 and the receiving rouge tray 3.

[0044] Next, the assembly method of the present invention's cartridge A and cartridge case A' will be described. As shown in Figure 12, the retaining tray 2 of cartridge A is inserted into the tray holder 9 of cartridge case A', and the retaining engaging portion 931 of the tray holder 9 is engaged with the retaining recess 24 of the retaining tray 2, thereby aligning and holding the retaining tray 2 at a predetermined angular position in the circumferential direction within the tray holder 9. In this state, the lower end of the rod-shaped cosmetic 1 is inserted into the retaining tray 2 using the alignment rib 94 of the tray holder 9 as a positioning guide for the angular position in the circumferential direction, and as shown in Figure 13, the rod-shaped cosmetic 1 and the retaining tray 2 are aligned and held at a predetermined angular position in the circumferential direction. After inserting the stick-shaped cosmetic 1, the positioning rib 94 of the red dye tray holder 9 is used as a positioning guide for the circumferential angular position, the temporary cap 10 is fitted onto the top of the red dye tray holder 9, and the engaging projection 951 of the red dye tray holder 9 is engaged with the engaging window 104 of the temporary cap 10, thereby housing the stick-shaped cosmetic 1 inside the cover portion 102 as shown in Figures 4 and 5. Through these steps, cartridge A is housed in cartridge case A', making it safe to carry and hold.

[0045] Next, the positioning at a predetermined angular position in the circumferential direction according to the present invention will be described. The rouge holder 9 of cartridge case A' and the retaining rouge tray 2 of cartridge A are positioned at a predetermined angular position in the circumferential direction by the engagement of the retaining engagement portion 931 of the rouge holder 9 and the retaining recess 24 of the retaining rouge tray 2. The rod-shaped cosmetic 1 of cartridge A and the retaining rouge tray 2 are positioned at a predetermined angular position in the circumferential direction by mounting the rod-shaped cosmetic 1 in the retaining rouge tray 2 using the alignment rib 94 as a positioning guide for the angular position in the circumferential direction. The retaining rouge tray 2 of cartridge A and the receiving rouge tray 3 of container B are positioned at a predetermined angular position in the circumferential direction by the engagement of the gripping projections 315 and 317 of the receiving rouge tray 3 with the gripping recesses 221 and 231 of the retaining rouge tray 2. The red pigment tray 3 and sleeve 4 of container B are positioned at a predetermined angular position in the circumferential direction by the guide projection 311 of the red pigment tray 3 and the guide groove 421 of the sleeve 4 engaging with each other so that they can slide vertically but cannot rotate. As a result, the rod-shaped cosmetic product 1 of cartridge A in cartridge case A' and the sleeve 4 of container B are positioned at a predetermined angular position in the circumferential direction. When cartridge case A' is attached to container B, the rod-shaped cosmetic product 1 and the sleeve 4 are automatically positioned at the predetermined angular position in the circumferential direction, and the shape of the tip of the sleeve 4 matches the shape of the tip of the rod-shaped cosmetic product 1.

[0046] In Embodiment 1 of the present invention, the dispensing mechanism B' housed within the container B was described as comprising a guide projection 311 and a male screw 321 provided on the receiving tray 3, a female screw 512 on the base cylinder 5 into which the male screw 321 of the receiving tray 3 engages, and a guide groove 421 on the sleeve 4 into which the guide projection 311 of the receiving tray 3 engages. However, the dispensing mechanism B' is not limited to this configuration, and any configuration different from that of Embodiment 1 is possible as long as the dispensing mechanism B' is positioned below the rod-shaped cosmetic product 1 and the rod-shaped cosmetic product 1 is directly housed within the sleeve 4. The following describes embodiments equipped with other dispensing mechanisms B'. Note that descriptions of parts that are the same as those described in Embodiment 1 of the present invention will be omitted. [Examples]

[0047] Figure 14 shows a cartridge-type retractable cosmetic container according to Embodiment 2 of the present invention. The retractable mechanism B' of Embodiment 2 consists of a guide projection 311 and a male screw 321 provided on the lipstick tray 3, an intermediate female screw 111 and an intermediate male screw 112 provided on the intermediate pipe 11 into which the male screw 321 of the lipstick tray 3 is screwed, a female screw 512 provided on the base cylinder 5 into which the intermediate male screw 112 is screwed, and a guide groove 421 provided on the sleeve 4 into which the guide projection 311 of the lipstick tray 3 engages. In this configuration, the intermediate pipe 11 is placed between the lipstick tray 3 and the base cylinder 5 of the retractable mechanism B' of Embodiment 1, and the overall length of the retractable mechanism B' can be shortened by folding it into an antenna shape.

[0048] The dispensing mechanism B' of the cartridge-type stick-shaped cosmetic dispensing container described in Examples 1 and 2 is consistent in that the guide projection 311 of the lipstick tray 3 engages with the guide groove 421 engraved on the inner wall of the sleeve 4, thereby housing the lipstick tray 3 within the sleeve 4 so that it can slide up and down but cannot rotate. In this configuration, if only one guide groove 421 is engraved on the inner wall of the sleeve 4, one guide projection 311 is also provided on the side wall of the lipstick tray 3 to match the guide groove 421, and is positioned at a predetermined angular position in the circumferential direction of the sleeve 4 and the lipstick tray 3. If multiple guide grooves 421 are engraved around the entire circumference of the inner wall of the sleeve 4, multiple guide projections 311 are also provided on the lipstick tray 3 to correspond to the guide grooves 421. The groove width of the guide groove 421 and the width of the guide projection 311 are made uniform, and the spacing between the guide groove 421 and the guide projection 311 is uneven to position the sleeve 4 and the red pigment tray 3 at a predetermined angular position in the circumferential direction. Conversely, the spacing between the guide groove 421 and the guide projection 311 is made uniform, and the groove width of the guide groove 421 and the width of the guide projection 311 are uneven to position the sleeve 4 and the red pigment tray 3 at a predetermined angular position in the circumferential direction. The number of guide grooves 421 and the number of guide projections 311 do not necessarily have to match, but the number of guide projections 311 should be less. [Examples]

[0049] Figure 15 shows a cartridge-type retractable container for a stick-shaped cosmetic product according to Embodiment 3 of the present invention. The retractable mechanism B' of Embodiment 3 consists of a guide projection 311 and a female screw 512 on the receiving tray 3, a male screw 321 on the base cylinder 5 that screws into the female screw 512 of the receiving tray 3, and a guide groove 421 on the sleeve 4 that engages with the guide projection 311 of the receiving tray 3 to guide the receiving tray 3 so that it cannot rotate. The receiving tray 3 has a pipe-shaped leg cylinder 33 hanging down from the lower end of the receiving cylinder 31. The leg cylinder 33 has a female screw 512 threaded into its inner circumferential wall and a guide projection 311 protruding from its outer wall. A threaded rod 32 that enters into the leg cylinder 33 of the receiving tray 3 is erected on the upper surface of the base cylinder 5. A male screw 321 that screws into the female screw 512 of the leg cylinder 33 is threaded into the outer wall of this threaded rod 32. A slit-shaped guide groove 421 is drilled in the side wall of the sleeve 4, into which the guide projection 311 of the red pigment tray 3 engages. [Examples]

[0050] Figure 16 shows a cartridge-type retractable container for a stick-shaped cosmetic product according to Embodiment 4 of the present invention. The retractable mechanism B' of Embodiment 4 consists of a guide projection 311 of the receiving tray 3, a guide groove 421 of the sleeve 4 through which the guide projection 311 of the receiving tray 3 passes and guides the receiving tray 3 so that it cannot rotate, and a spiral groove 513 of the spiral cylinder 12 into which the guide projection 311 of the receiving tray 3, which has passed through the guide groove 421 of the sleeve 4, is screwed. The receiving tray 3 has a pipe-shaped leg cylinder 33 hanging down from the lower end of the receiving cylinder 31. The guide projection 311 is provided on the outer wall of this leg cylinder 33. A slit-shaped guide groove 421 is drilled in the side wall of the sleeve 4 through which the guide projection 311 of the receiving tray 3 passes. The lower part of the sleeve 4 is rotatably inserted into the spiral cylinder 12, and a female thread-shaped spiral groove 513 is screwed into the inner wall, into which the guide projection 311 of the red dye tray 3, which penetrates the guide groove 421 of the sleeve 4, is screwed.
