Stick-shaped cosmetic dispenser

Abstract

To provide a container for feeding stick-shaped cosmetics, which allows selection of a method of directly filling and molding cosmetics into the container as a method for holding stick-shaped cosmetics in a tray member, allows separate disposal of metal members with a simple operation, and prevents unintended disassembly in normal use. [Solution] The lifting mechanism is inserted through the mechanism insertion hole at the bottom of the hakama tube, and the sleeve-hakama tube abutment portion abuts the hakama tube-sleeve abutment portion, preventing the sleeve from slipping out upward, and the threaded rod-hakama tube engagement boss and the hakama tube-screwed rod engagement hole removably engage to combine the lifting mechanism and exterior member, forming a container for dispensing stick-shaped cosmetic material. When the container is to be disposed of, the threaded rod is pressed downward via the sleeve to release the engagement between the threaded rod and the hakama tube, and the lifting mechanism can be separated, sorted, disposed of, or recycled.

Description

[Technical Field]

[0001] The present invention relates to a container for dispensing stick-shaped cosmetics, such as lipstick or stick foundation, which contains a rotary dispensing mechanism that raises and lowers the stick-shaped cosmetics by rotating the container relative to the container. [Background technology]

[0002] Known containers for storing stick-type cosmetics such as lipstick and stick foundation include a stick-type cosmetic dispenser equipped with a rotary dispenser mechanism that raises and lowers the stick-type cosmetic by rotating the container relative to itself. These stick-type cosmetic dispenser containers are composed of a combination of multiple components. These components are made of a wide variety of materials, such as synthetic resins and metals, each selected for its own functionality, decorativeness, and other characteristics. In conventional stick-type cosmetic dispenser containers, these components are assembled in a non-disassembled manner to prevent malfunction during use. From the perspective of environmental conservation, however, it is desirable for the container to be easily disassembled and disposed of separately after use, for the purpose of proper waste disposal and recycling. Thus, as in Patent Documents 1, 2, and 3, stick-type cosmetic dispenser containers have been proposed in which the metal and synthetic resin components can be separated and disposed of separately when the container is discarded. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-225322 [Patent Document 2] Japanese Patent Application Publication No. 10-75821 [Patent Document 3] Japanese Patent Application Laid-Open No. 2002-209631 Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 proposes a container for storing lipstick or other items, in which a flange-shaped bulge locking portion (14, 14B) is provided on the side wall of a metal outer tube member (1), a bottom member (4) and a lid fitting member (9) are separably screwed together, and the bulge locking portion (14, 14B) of the outer tube member (1) is rotatably and non-detachably sandwiched between the bottom member (4) and the lid fitting member (9). By removing the lid fitting member (9) from the bottom member (4), the outer tube member (1) can be separated and disposed of separately. However, the lid fitting member (9) also serves the function of fitting and holding a lid (10). Therefore, it was necessary to firmly connect (screw) the lid fitting member (9) with the lid (10) to prevent unintentional disassembly due to stress applied to the lid fitting member (9) when the lid (10) is attached or detached, or friction or impact applied to the lid (10) when stored in a cosmetic pouch or the like. In addition, the lid fitting member (9) has a fitting portion (11) that protrudes from the lid (4), and the lid fitting member (9) must be separated by holding the fitting portion (11), but the portion to be held is small, making the operation difficult.

[0005] Patent Document 2 proposes a storage container for lipstick or the like, in which a flange portion (10) protruding in the circumferential direction is provided at the lower end of a metal tubular member (8, 8A), and a bottom cover (18, 18A, 18B, 18C) is separably screwed to a bottom cover member (1, 1A, 1B) so that the flange portion (10) of the tubular member (8, 8A) is rotatably sandwiched between the bottom cover member (1, 1A, 1B) and the bottom cover (18, 18A, 18B, 18C). By removing the bottom cover (18, 18A, 18B, 18C) from the bottom cover member (1, 1A, 1B), the tubular member (8, 8A) can be separated and disposed of separately. Compared to the lid fitting member of Patent Document 1, this bottom lid (18, 18A, 18B, 18C) does not need to hold the cap (21) and has a smaller exposed area than the bottom lid members (1, 1A, 1B). As a result, frictional force is small during use or carrying, and the influence of external forces is extremely small. However, in the storage container of Patent Document 2, the lower end of the pan member (13) abuts against the bottom lid (18, 18A, 18B, 18C), marking the lower limit of the pan member (13). Therefore, if the pan member (13) is lowered to its lower limit and the lowering operation is continued, the pan member (13) and the cylindrical member (8, 8A) push the bottom lid (18, 18A, 18B, 18C) downward in the bottom lid member (1, 1A, 1B) in the direction of separation. Because a force is applied to the bottom lids (18, 18A, 18B, 18C) in the direction of separation each time the lipstick (14) is stored, to prevent unintentional disassembly, the bottom lids (18, 18A, 18B, 18C) and the bottom lids (18, 18A, 18B, 18C) need to be firmly screwed together, as in Patent Document 1. In addition, the bottom lids (18, 18A, 18B, 18C) have a smaller exposed area than the bottom lids (1, 1A, 1B) and therefore have fewer gripping portions for unscrewing the bottom lids (18, 18A, 18B, 18C), making the separation operation difficult.

[0006] Patent Document 3 proposes a storage container for lipstick or the like, in which a flange portion (4) is provided on a metal inner cylindrical member (3), and the flange portion (4) of the inner cylindrical member (3) is rotatably sandwiched between the lower end of a lid fitting member (6) inserted and fastened from the upper end of a bottom member (1, 1A) and a screw frame member (12, 12A) detachably inserted and engaged from the lower end of the bottom member (1, 1A). In this container, by pushing the inner cylindrical member (3) downward, the engagement between the screw frame member (12, 12A) and the bottom member (1, 1A) is released and the container can be separated. In Example 1, the disk member (8) and the screw frame member (12, 12A) can be separated, and in Example 2, the inner cylindrical member (3), the disk member (8), and the screw frame member (12, 12A) can be separated.

[0007] The screw frame members (12, 12A) have only a small exposed bottom surface at the bottom end of the lid member (1, 1A). In other words, no force is applied to the screw frame members (12, 12A) in the direction of separation during normal use, such as when attaching or detaching the lid (7) or operating the feeding mechanism, and the screw frame members (12, 12A) will not unintentionally separate. In addition, the inner tube member (3) that presses down the screw frame members (12, 12A) is usually covered by the lid (7), so there is no risk of external force being applied to the inner tube member (3). The inner tube member (3) is pushed down to separate it from the screw frame member (12, 12A) and the slat member (1, 1A). This operation allows for the application of a greater force than the operation of pinching and pulling out, thereby strengthening the engagement force between the screw frame member (12, 12A) and the slat member (1, 1A), completely preventing unintentional separation under normal use. Furthermore, the operation of pushing down the inner tube member (3) does not require holding the inner tube member (3), which simplifies the operation of separating the screw frame member (12, 12A), etc., and has other advantages.

[0008] However, unlike the storage containers of Patent Documents 1 and 2, the storage container of Patent Document 3 has an engagement groove (5) engraved long in the axial direction on the inner surface of the inner cylindrical member (3) that guides the tray member (8) so that it cannot rotate but can slide up and down. This engagement groove (5) reaches up to the top of the tray member (8). Therefore, it is not possible to mold a stick-shaped cosmetic material (9) using the "in-container cosmetic filling and molding method" in which molten cosmetic material is directly filled into the inner cylindrical member (3), and is limited to the "external cosmetic material molding and mounting method" in which a stick-shaped cosmetic material (9) that has already been molded into a predetermined shape using a mold is mounted on the tray member (8).

[0009] In view of the above circumstances, the present invention aims to provide a container for dispensing stick-type cosmetics, which allows the user to choose between a "cosmetic material molding and mounting method outside the container" and a "cosmetic material filling and molding method inside the container" as the method for mounting the stick-type cosmetics (9) on the tray member (8), allows for the separate disposal of metal components with simple operations, and prevents unintentional disassembly under normal use conditions. [Means for solving the problem]

[0010] In order to solve the above problems, the stick-type cosmetic material dispensing container according to the present invention comprises a lifting mechanism 82 comprising at least a retaining tube 2, a sleeve 3, and a threaded rod 4, and an exterior member 86 comprising at least a cap 7 and a hakama tube 5, which are detachably engaged together. Of these, at least one member constituting the lifting mechanism 82 is molded from thin-walled metal, and the other members are molded from synthetic resin.

[0011] The holding tube 2 of the lifting mechanism 82 has a bottomed, tubular cosmetic holding section 201 at its upper part that holds the lower end of the stick-shaped cosmetic 1. The lower part of the holding tube 2 is provided with a holding tube-sleeve sliding contact section 207 with an enlarged outer diameter, and a stepped holding tube-sleeve abutment section 203 is formed at the upper end of the holding tube-sleeve sliding contact section 207. A holding tube-sleeve guide boss 202 protrudes from the outer peripheral wall of the holding tube-sleeve sliding contact section 207. A drive female screw 204 is threaded into the lower part of the holding tube 2, and the lower end forms a holding tube-threaded rod abutment section 206. The holding tube 2 is mounted within the sleeve 3 of the lifting mechanism 82 so that it can slide up and down.

[0012] The upper part of the sleeve 3 forms a sleeve-cosmetic sliding surface 301 having an inner diameter that is the same as or slightly larger than the outer diameter of the cosmetic holding portion 201 of the holding tube 2. The lower part of the sleeve 3 forms a sleeve-holding tube sliding surface 307 having an inner diameter slightly larger than the outer diameter of the holding tube-sleeve sliding portion 207 of the holding tube 2. Below this sleeve-holding tube sliding surface 307, a sleeve-threaded rod sliding surface 305 is provided, the inner diameter of which is slightly larger than the outer diameter of the holding tube-sleeve guide boss 202. The lower end of the sleeve 3 forms a sleeve-threaded rod abutment portion 306. A stepped sleeve inner wall step 303 is formed between the sleeve-holding tube sliding surface 307 and the sleeve-cosmetic sliding surface 301. A stepped sleeve-sleeve tube abutment portion 304 is formed on the outer wall of the sleeve 3 facing this sleeve inner wall step 303. A sleeve-retaining tube guide groove 302, which engages with the retaining tube-sleeve guide boss 202 and guides the retaining tube 2 non-rotatably but vertically slidably, is engraved on the inner wall of the sleeve-retaining tube sliding surface 307, extending in the axial direction from the lower end of the sleeve-retaining tube sliding surface 307. The threaded rod 4 of the lifting mechanism 82 is inserted from the lower end of the retaining tube 2.

[0013] A male drive screw 401 that screws into the female drive screw 204 of the retaining tube 2 is threadedly provided on the outer wall of the threaded rod 4. A threaded rod-sleeve sliding portion 403 with an outer diameter slightly smaller than the inner diameter of the sleeve-threaded rod sliding surface 305 is provided below the lower end of the male drive screw 401, and a stepped threaded rod-retaining tube abutment portion 402 is formed at the upper end of the threaded rod-sleeve sliding portion 403. A threaded rod-sleeve coupling portion 405 with an outer diameter larger than the outer diameter of the lower part of the sleeve 3 is provided below the threaded rod-sleeve sliding portion 403, and a stepped threaded rod-sleeve abutment portion 404 is formed at the upper end of the threaded rod-sleeve coupling portion 405. A threaded rod-sleeve anti-rotation boss 405e that is long in the axial direction and a threaded rod-sleeve engagement boss 405a that is long in the circumferential direction are protruded from the outer wall of the threaded rod-sleeve coupling portion 405. The sleeve-threaded rod abutment portion 306 of the sleeve 3 abuts against the threaded rod-sleeve abutment portion 404 , and the threaded rod-shank tube coupling portion 405 of the threaded rod 4 protrudes from the lower end of the sleeve 3 .

[0014] The sheath tube 5 of the exterior member 86 has a pipe shape that penetrates vertically, and has a sheath tube-sleeve through-hole 509 at its upper end, the inner diameter of which is slightly larger than the outer diameter of the upper part of the sleeve 3. A stepped sheath tube-sleeve abutment portion 504 is formed on the inner peripheral wall of the opening of this sheath tube-sleeve through-hole 509, with which the sleeve-sheath tube abutment portion 304 abuts. The upper part of the sheath tube 5 is provided with a sheath tube-cap fitting portion 507 into which the cap 7 is detachably fitted. The lower part of the sheath tube 5 is provided with a sheath tube-threaded rod joint 506, the inner diameter of which is slightly larger than the outer diameter of the threaded rod-sheath tube joint portion 405 of the threaded rod 4. A mechanism insertion hole 503 having an inner diameter slightly larger than the outer diameters of the threaded rod-to-shakama tube anti-rotation boss 405e and the threaded rod-to-shakama tube engagement boss 405a is drilled at the lower end of the shakama tube 5. A shakama tube-to-threaded rod anti-rotation slot 506a that non-rotatably engages with the threaded rod-to-shakama tube anti-rotation boss 405e, and a shakama tube-to-threaded rod engagement hole 506b that detachably engages with the threaded rod-to-shakama tube engagement boss 405a are drilled in the inner wall.

[0015] The sleeve 3 of the lifting mechanism 82 is inserted through the mechanism insertion hole 503 of the helical tube 5 of the exterior member 86, and the sleeve-helical tube abutment portion 304 abuts against the helical tube-sleeve abutment portion 504 to prevent the sleeve 3 from coming off upward. In this state, the threaded rod-helical tube engagement boss 405a and the helical tube-helical tube engagement hole 506b are detachably engaged, and the threaded rod 4 and the helical tube 5 are detachably engaged to combine the lifting mechanism 82 and the exterior member 86.

[0016] By pushing the sleeve 3 downward, the threaded rod 4 is pushed out via the sleeve 3, and the engagement between the threaded rod-Hawk tube engagement boss 405a and the Hawk tube-threaded rod engagement hole 506b is released. As a result, the lifting mechanism 82 is detached from the exterior member 86, and the retaining tube 2, the sleeve 3, and the threaded rod 4 can be separated and disposed of separately. Alternatively, the exterior member 86 can be reused by replacing it with a new lifting mechanism 82. [Effects of the Invention]

[0017] The stick-type cosmetic material feeding container of the present invention is configured as described above, and the sleeve-holding tube guide groove 302, which engages with the holding tube-sleeve guide boss 202 of the holding tube 2 and guides the holding tube 2 non-rotatably but vertically slidably, is located below the sleeve-holding tube sliding surface 307. As a result, the sleeve-cosmetic material sliding surface 301 that accommodates the stick-type cosmetic material 1 is smooth, and it is possible to implement means for attaching the stick-type cosmetic material 1 using an "in-container cosmetic material filling and molding method" in addition to an "external cosmetic material molding and attachment method."

[0018] The stick-type cosmetic material dispensing container of the present invention is configured as described above, and similarly to Patent Document 3, the threaded rod 4 can be pushed down by pushing down the sleeve 3, thereby disengaging the threaded rod-to-shank barrel engagement boss 405a from the shako barrel-to-screw rod engagement hole 506b, allowing the lifting mechanism 82 to be easily detached from the exterior member 86. The detached lifting mechanism 82 can be separated into the retaining barrel 2, the sleeve 3, and the threaded rod 4, which can then be disposed of separately. Alternatively, the exterior member 86 can be reused by replacing it with a new lifting mechanism 82. Furthermore, this removal operation of pushing down the threaded rod 4 is an operation that is never performed under normal use conditions, and a greater force can be applied to "pull down" than to "pull out," making it possible to strengthen the engagement force between the exterior member 86 and the lifting mechanism 82 to a degree that prevents the lifting mechanism 82 from accidentally falling off.

[0019] The stick-type cosmetic material dispensing container of the present invention is configured as described above, and all of the components of the lifting mechanism 82 are assembled from the rear (below). Therefore, the stick-type cosmetic material dispensing container of the present invention has many advantages, such as high assembly efficiency and ease of automation of assembly.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Next, two embodiments for carrying out the present invention will be described. The stick-type cosmetic material dispensing container of the present invention comprises a lifting mechanism 82 for raising and lowering the stored stick-type cosmetic material 1, and an exterior member 86 with an ornamental exterior that is detachably engaged with each other. The lifting mechanism 82 comprises at least a holding tube 2, a sleeve 3, and a threaded rod 4, and houses the stick-type cosmetic material 1. The exterior member 86 comprises at least a cap 7 and a hakama tube 5. Of these, at least the sleeve 3 of the lifting mechanism 82 is molded from thin-walled metal, and the other members are molded from synthetic resin.

[0022] A first embodiment of the present invention will be described. The holding tube 2 of the lifting mechanism 82 has a bottomed, tubular cosmetic holding portion 201 at its upper portion, which holds the held portion 102 at the lower end of the stick-shaped cosmetic 1. The lower portion of the holding tube 2 is provided with a holding tube-sleeve sliding portion 207 whose outer diameter is larger than that of the upper portion, and a stepped holding tube-sleeve abutment portion 203 is formed at the upper end of the holding tube-sleeve sliding portion 207. A holding tube-sleeve guide boss 202 protrudes from the outer peripheral wall of the holding tube-sleeve sliding portion 207. A drive female screw 204 is threaded into the lower portion of the holding tube 2, and the lower end forms a holding tube-threaded rod abutment portion 204a. The holding tube 2 is mounted within the sleeve 3 of the lifting mechanism 82 so as to be able to slide up and down.

[0023] The upper part of the sleeve 3 forms a sleeve-cosmetic sliding surface 301 having an inner diameter that is the same as or slightly larger than the outer diameter of the cosmetic holding portion 201 of the holding tube 2. The lower part of the sleeve 3 forms a sleeve-holding tube sliding surface 307 having an inner diameter slightly larger than the outer diameter of the holding tube-sleeve sliding portion 207 of the holding tube 2. Below this sleeve-holding tube sliding surface 307, a sleeve-threaded rod sliding surface 305 is provided, the inner diameter of which is slightly larger than the outer diameter of the holding tube-sleeve guide boss 202. The lower end of the sleeve 3 forms a sleeve-threaded rod abutment portion 306. A stepped sleeve inner wall step 303 is formed between the sleeve-holding tube sliding surface 307 and the sleeve-cosmetic sliding surface 301. A stepped sleeve-sleeve tube abutment portion 304 is formed on the outer wall of the sleeve 3 facing this sleeve inner wall step 303. A sleeve-retaining tube guide groove 302, which engages with the retaining tube-sleeve guide boss 202 and guides the retaining tube 2 non-rotatably but vertically slidably, is engraved on the inner wall of the sleeve-retaining tube sliding surface 307, extending in the axial direction from the lower end of the sleeve-retaining tube sliding surface 307. The threaded rod 4 of the lifting mechanism 82 is inserted from the lower end of the retaining tube 2.

[0024] A male drive screw 401 that threadably engages with the female drive screw 204 of the retaining tube 2 is threadedly provided on the outer wall of the threaded rod 4. A threaded rod-sleeve sliding portion 403 having an outer diameter slightly smaller than the inner diameter of the sleeve-threaded rod sliding surface 305 is provided below the lower end of the male drive screw 401, and a stepped threaded rod-retaining tube abutment portion 402 is formed at the upper end of the threaded rod-sleeve sliding portion 403. A threaded rod-sleeve coupling portion 405 having an outer diameter larger than the outer diameter of the lower part of the sleeve 3 is provided below the threaded rod-sleeve sliding portion 403, and a stepped threaded rod sleeve abutment portion 404 is formed at the upper end of the threaded rod-sleeve coupling portion 405. A threaded rod-sleeve anti-rotation boss 405e that is long in the axial direction and a threaded rod-sleeve engagement boss 405a that is long in the circumferential direction are protruded from the outer wall of the threaded rod-sleeve coupling portion 405. The sleeve-threaded rod abutment portion 306 of the sleeve 3 abuts against the threaded rod-sleeve abutment portion 404 , and the threaded rod-shank tube coupling portion 405 of the threaded rod 4 protrudes from the lower end of the sleeve 3 .

[0025] The hexagonal tube 5 of the exterior member 86 has a pipe shape that penetrates vertically, and at its upper end is a hexagonal tube-sleeve through-hole 509 with an inner diameter slightly larger than the outer diameter of the upper part of the sleeve 3. The inner peripheral wall of the opening of this hexagonal tube-sleeve through-hole 509 is formed with a stepped hexagonal tube-sleeve abutment portion 504 with which the sleeve-hexagonal tube abutment portion 304 abuts. The upper part of the hexagonal tube 5 is provided with a hexagonal tube-cap fitting portion 507 into which the cap 7 is detachably fitted. At the lower end of the hexagonal tube 5 is opened a mechanism insertion hole 503 with an inner diameter slightly larger than the outer diameter of the threaded rod-hexagonal tube anti-rotation boss 405e and the threaded rod-hexagonal tube engagement boss 405a. A hexagonal tube-threaded rod coupling portion 506 having an inner diameter slightly larger than the outer diameter of the threaded rod-hexagonal tube coupling portion 405 of the threaded rod 4 is provided within this mechanism insertion hole 503. A hexagonal tube-threaded rod anti-rotation slot 506a that non-rotatably engages with the threaded rod-hexagonal tube anti-rotation boss 405e, and a hexagonal tube-threaded rod engagement hole 506b that detachably engages with the threaded rod-hexagonal tube engagement boss 405a are drilled on the inner wall of this hexagonal tube-threaded rod coupling portion 506.

[0026] The sleeve 3 of the lifting mechanism 82 is inserted through the mechanism insertion hole 503 of the helical tube 5 of the exterior member 86, and the sleeve-helical tube abutment portion 304 of the sleeve 3 abuts against the helical tube-sleeve abutment portion 504, preventing the sleeve 3 from coming out of the upward direction. In this state, the threaded rod-helical tube engagement boss 405a and the helical tube-threaded rod engagement hole 506b are detachably engaged, and the threaded rod 4 and the helical tube 5 are detachably engaged to combine the lifting mechanism 82 and the exterior member 86. At the same time, the sleeve 3 is rotatably but non-detachably held between the helical tube-sleeve abutment portion 504 and the threaded rod-sleeve abutment portion 404, and the retaining tube 2 is slidably held up and down but non-rotatably between the sleeve inner wall step portion 303 and the threaded rod-retaining tube abutment portion 402.

[0027] By pushing the sleeve 3 downward, the threaded rod 4 is pushed out via the sleeve 3, and the engagement between the threaded rod-Hawk tube engagement boss 405a and the Hawk tube-threaded rod engagement hole 506b is released. As a result, the lifting mechanism 82 is separated from the exterior member 86, and the retaining tube 2, the sleeve 3, and the threaded rod 4 can be separated and disposed of separately.

[0028] Next, a second embodiment of the present invention will be described. The holding tube 2 of the lifting mechanism 82 has, at its upper part, a bottomed, tubular cosmetic holding portion 201 that holds the held portion 102 at the lower end of the stick-shaped cosmetic 1. The lower part of the holding tube 2 is provided with a holding tube-sleeve sliding portion 207 that has a larger outer diameter than the upper part, and a stepped holding tube-sleeve abutment portion 203 is formed at the upper end of the holding tube-sleeve sliding portion 207. A holding tube-sleeve guide boss 202 protrudes from the outer peripheral wall of the holding tube-sleeve sliding portion 207. A drive female screw 204 is threaded into the lower part of the holding tube 2, and the lower end forms a holding tube-threaded rod abutment portion 204a. The holding tube 2 is mounted within the sleeve 3 of the lifting mechanism 82 so that it can slide up and down.

[0029] The upper part of the sleeve 3 has an inner diameter that is the same as or slightly larger than the outer diameter of the cosmetic holding portion 201 of the holding tube 2, and forms a sleeve-cosmetic sliding surface 301. The lower part of the sleeve 3 forms a sleeve-holding tube sliding surface 307, whose inner diameter is slightly larger than the outer diameter of the holding tube-sleeve sliding portion 207 of the holding tube 2. Below this sleeve-holding tube sliding surface 307, a sleeve-threaded rod sliding surface 305 is provided, whose inner diameter is slightly larger than the outer diameter of the holding tube-sleeve guide boss 202. A stepped sleeve inner wall step 303 is formed between the sleeve-holding tube sliding surface 307 and the sleeve-cosmetic sliding surface 301. A stepped sleeve-sleeve tube abutment portion 304 is formed on the outer wall of the sleeve 3 facing this sleeve inner wall step 303. A sleeve-retaining tube guide groove 302, which engages with the retaining tube-sleeve guide boss 202 and guides the retaining tube 2 up and down slidably but not rotates, is engraved on the inner wall of the sleeve-retaining tube sliding surface 307, extending axially from the lower end of the sleeve-retaining tube sliding surface 307. A sleeve-threaded rod mounting projection 305a is circumferentially protruded from the inner wall of the sleeve-threaded rod sliding surface 305. The threaded rod 4 of the lifting mechanism 82 is inserted from the lower end of the retaining tube 2.

[0030] A drive male screw 401 that screws into the drive female screw 204 of the retaining tube 2 is threadedly provided on the outer wall of the threaded rod 4. A threaded rod-sleeve sliding portion 403 with an outer diameter slightly smaller than the inner diameter of the sleeve-threaded rod sliding surface 305 is provided below the lower end of the drive male screw 401, and a stepped threaded rod-retaining tube abutment portion 402 is formed at the upper end of this threaded rod-sleeve sliding portion 403. A threaded rod-sleeve coupling portion 405 with an outer diameter larger than the outer diameter of the lower part of the sleeve 3 is provided below the threaded rod-sleeve sliding portion 403, and a threaded rod-sleeve coupling boss 405e that is long in the axial direction and a threaded rod-sleeve coupling boss 405a that is long in the circumferential direction are protruded from the outer wall of this threaded rod-sleeve coupling portion 405. A threaded rod-sleeve shaft mounting groove 403b is carved on the outer peripheral wall of the threaded rod-sleeve sliding contact portion 403, and the sleeve-threaded rod shaft mounting protrusion 305a of the sleeve 3 is rotatably and non-detachably engaged with the groove. At this time, the threaded rod-sleeve coupling portion 405 of the threaded rod 4 protrudes from the lower end of the sleeve 3.

[0031] The lifting mechanism 82 rotatably and non-detachably engages the sleeve 3 and the threaded rod 4 by engaging the threaded rod-sleeve shaft mounting groove 403b of the threaded rod 4 with the sleeve-threaded rod shaft mounting protrusion 305a of the sleeve 3. At the same time, the retaining tube 2 holds the retaining tube-sleeve abutment portion 203 and the retaining tube-threaded rod abutment portion 204a between the sleeve inner wall step portion 303 of the sleeve 3 and the threaded rod-retaining tube abutment portion 401a of the threaded rod 4 so that they can slide up and down but cannot rotate.

[0032] The hexagonal tube 5 of the exterior member 86 has a pipe shape that penetrates vertically, and at its upper end is a hexagonal tube-sleeve through-hole 509 with an inner diameter slightly larger than the outer diameter of the upper part of the sleeve 3. A stepped hexagonal tube-sleeve abutment portion 504 is formed on the inner peripheral wall of the opening of this hexagonal tube-sleeve through-hole 509, with which the sleeve-hexagonal tube abutment portion 304 abuts. A hexagonal tube-cap fitting portion 507 into which the cap 7 is detachably fitted is provided at the upper part of the hexagonal tube 5. At the lower end of the hexagonal tube 5 is a mechanism insertion hole 503 with an inner diameter slightly larger than the outer diameter of the threaded rod-hexagonal tube anti-rotation boss 405e and the threaded rod-hexagonal tube engagement boss 405a. A hexagonal tube-threaded rod coupling portion 506 having an inner diameter slightly larger than the outer diameter of the threaded rod-hexagonal tube coupling portion 405 of the threaded rod 4 is provided within this mechanism insertion hole 503. A hexagonal tube-threaded rod anti-rotation slot 506a that non-rotatably engages with the threaded rod-hexagonal tube anti-rotation boss 405e, and a hexagonal tube-threaded rod engagement hole 506b that detachably engages with the threaded rod-hexagonal tube engagement boss 405a are drilled on the inner wall of this hexagonal tube-threaded rod coupling portion 506.

[0033] The sleeve 3 of the lifting mechanism 82 is inserted through the mechanism insertion hole 503 of the helical tube 5 of the exterior member 86, and the sleeve-helical tube abutment portion 304 of the sleeve 3 abuts against the helical tube-sleeve abutment portion 504, preventing the sleeve 3 from coming off upward. In this state, the threaded rod-helical tube engagement boss 405a and the helical tube-helical tube engagement hole 506b are detachably engaged, and the threaded rod 4 and the helical tube 5 are detachably engaged, thereby combining the lifting mechanism 82 and the exterior member 86.

[0034] By pushing the sleeve 3 downward, the threaded rod 4 is pushed out via the sleeve 3, and the engagement between the threaded rod-Hawk tube engagement boss 405a and the Hawk tube-threaded rod engagement hole 506b is released. As a result, the lifting mechanism 82 is separated from the exterior member 86, and a new lifting mechanism 82 can be inserted into the exterior member 86. [Example]

[0035] Specific examples of the present invention will be described in detail below with reference to the drawings. In this specification, unless otherwise specified, the direction in which a stick-shaped cosmetic material protrudes when the cosmetic material is used is referred to as "up," and the clockwise direction when viewed from above is referred to as "right-handed."

[0036] A stick-type cosmetic material dispensing container according to Example 1 of the present invention will be described with reference to Figures 1 to 7. As shown in Figure 6, the stick-type cosmetic material dispensing container according to Example 1 of the present invention comprises a stick-type cosmetic material 1, a holding tube 2, a sleeve 3, a threaded rod 4, a hakama tube 5, a sliding resistor 6, and a cap 7. Of these, the holding tube 2, the sleeve 3, the threaded rod 4, and the sliding resistor 6 constitute an elevating mechanism 82 that moves the stick-type cosmetic material 1 up and down. The hakama tube 5 and the cap 7 also constitute an exterior member 86 that protects the stick-type cosmetic material 1 and the elevating mechanism 82.

[0037] The stick-shaped cosmetic 1 is a stick-shaped cosmetic that is consumed by being directly applied or rubbed onto the human body, or by being attached to or impregnated into an applicator, such as lip cosmetics such as lipstick or lip balm, or skin cosmetics such as stick-type concealer, and is generally stick-shaped. The stick-shaped cosmetic 1 has an application section 101 at its upper end, a small-diameter held section 102 at its lower end, and a stepped cosmetic-holding tube abutment section 103 at the upper end of the held section 102.

[0038] The holding tube 2 is a component of the elevating mechanism 82 that holds the stick-shaped cosmetic 1 and raises and lowers the stick-shaped cosmetic 1 in the vertical direction, and is molded from synthetic resin. A cylindrical cosmetic holding portion 201 with a bottom is provided at the upper end of the holding tube 2. The outer diameter of the cosmetic holding portion 201 is approximately the same as the outer diameter of the application portion 101 of the stick-shaped cosmetic 1, and its inner diameter is the same as or slightly larger than the outer diameter of the held portion 102 of the stick-shaped cosmetic 1. A ring-shaped cosmetic holding protrusion 201a is provided on the inner surface of the cosmetic holding portion 201. A tongue-shaped cosmetic holding tongue 201b is provided on the inner bottom surface of the cosmetic holding portion 201.

[0039] A retaining tube-sleeve sliding contact portion 207 having an outer diameter larger than that of the upper portion of the retaining tube 2 is provided at the lower portion of the retaining tube 2. A stepped retaining tube-sleeve abutment portion 203 is formed at the upper end of the retaining tube-sleeve sliding contact portion 207. A retaining tube-sleeve guide boss 202 protrudes from the outer surface of the retaining tube-sleeve sliding contact portion 207. In this embodiment 1, eight retaining tube-sleeve guide bosses 202 are evenly arranged around the outer periphery of the retaining tube-sleeve sliding contact portion 207. A drive female screw 204 is provided on the inner surface of the lower end of the retaining tube 2. This drive female screw 204 protrudes in a multi-step or single-step protrusion shape and is arranged in two locations symmetrically in the circumferential direction. The upper end of this drive female screw 204 becomes the retaining tube-threaded rod abutment portion 204a. At two locations between the drive female screws 204, retaining cylinder deformation slits 205 are provided which start from the lower end of the retaining cylinder 2 and extend in the axial upward direction, penetrating from the inside to the outside.

[0040] The sleeve 3 is an element of the elevating mechanism 82 that raises and lowers the stick-shaped cosmetic material 1 in the vertical direction, and is also a protective member that supports the stick-shaped cosmetic material 1 and prevents deformation and breakage of the stick-shaped cosmetic material 1, and is made of thin metal such as aluminum. The sleeve 3 has a thick, stepped cylindrical shape at the bottom, and the upper part forms the sleeve-cosmetic material sliding surface 301. The inner diameter of this sleeve-cosmetic material sliding surface 301 is the same as or slightly larger than the outer diameter of the application portion 101 of the stick-shaped cosmetic material 1 and the outer diameter of the cosmetic material holding portion 201 of the holding tube 2.

[0041] The inner and outer diameters of the lower portion of the sleeve-cosmetic sliding surface 301 are enlarged, and the inner surface forms a sleeve-retaining tube sliding surface 307. The inner diameter of the sleeve-retaining tube sliding surface 307 is slightly larger than the outer diameter of the retaining tube-sleeve sliding portion 207 of the retaining tube 2. A stepped sleeve inner wall step 303 is formed at the upper end of the sleeve-retaining tube sliding surface 307, and a stepped sleeve-screw tube abutment portion 304 is formed on the outer wall of the sleeve 3 opposite this sleeve inner wall step 303. A sleeve-threaded rod sliding surface 305, the inner diameter of which is enlarged, is provided below the sleeve-retaining tube sliding surface 307. The inner diameter of the sleeve-threaded rod sliding surface 305 is slightly larger than the outer diameter of the retaining tube-sleeve guide boss 202 of the retaining tube 2. As a result, the thickness of the sleeve-retaining tube sliding contact surface 307 is thinner than the thickness of the sleeve-retaining tube sliding contact surface 307. The lower end of the sleeve 3 forms a sleeve-threaded rod contact portion 306.

[0042] A sleeve-retaining tube guide groove 302 is engraved on the inner wall of the sleeve-retaining tube sliding surface 307. In this embodiment 1, there are eight grooves, the same number as the retaining tube-sleeve guide bosses 202 of the retaining tube 2, and they are evenly arranged in the circumferential direction. The sleeve-retaining tube guide groove 302 is engraved long in the axial direction, and its lower end opens into a stepped portion at the upper end of the sleeve-threaded rod sliding surface 305. The inner diameter of the sleeve-retaining tube guide groove 302 is approximately the same as the inner diameter of the sleeve-threaded rod sliding surface 305 and slightly larger than the outer diameter of the retaining tube-sleeve guide boss 202. The axial width of the sleeve-retaining tube guide groove 302 is slightly wider than the axial width of the retaining tube-sleeve guide boss 202.

[0043] The threaded rod 4 is molded from synthetic resin and serves as a component of the elevating mechanism 82 that raises and lowers the stick-type cosmetic 1 in the vertical direction, as well as a locking member that prevents unintended separation of the various components. The threaded rod 4 has a stepped cylindrical shape with a thicker lower portion. A drive male screw 401 is threaded onto the outer surface of the upper portion of the threaded rod 4. The drive male screw 401 is a two-thread left-handed spiral groove, and its upper end does not reach the tip of the threaded rod 4. The upper end of the drive male screw 401 forms the threaded rod-retaining tube abutment portion 401a. The outer diameter (thread diameter) of the drive male screw 401 is slightly smaller than the root diameter of the drive female screw 204 of the retaining tube 2.

[0044] 6 and 7, the drive male screw 401 of the threaded rod 4 is a bolt-like, full-circumference screw, but it may also be an intermittent screw with a flat parting, like a typical split-type male screw. Furthermore, while the drive male screw 401 is described as a double-start left-handed screw in the description of the embodiments of the present invention, the present invention is not limited to this. For example, if the drive male screw 401 is a single-start screw, the lead will be half that of a double-start screw, resulting in a finer delivery lead and being compatible with softer, more fragile stick-type cosmetic materials 1. Furthermore, if the drive male screw 401 is a right-handed screw, the direction of rotation for delivering the stick-type cosmetic material 1 can be reversed.

[0045] A threaded rod-sleeve sliding portion 403 with an enlarged outer diameter is provided below the drive male screw 401 of the threaded rod 4, and a stepped threaded rod-retaining tube abutment portion 402 is formed at the upper end of this threaded rod-sleeve sliding portion 403. The outer diameter of this threaded rod-sleeve sliding portion 403 is slightly smaller than the inner diameter of the sleeve-threaded rod sliding surface 305 of the sleeve 3. An O-ring groove 403a is engraved in the circumferential direction on the outer surface of the threaded rod-sleeve sliding portion 403.

[0046] A threaded rod-to-sleeve coupling portion 405 with an enlarged outer diameter is provided below the threaded rod-to-sleeve sliding contact portion 403, and a stepped threaded rod-to-sleeve contact portion 404 is formed at the upper end of the threaded rod-to-sleeve coupling portion 405. The outer diameter of the threaded rod-to-sleeve coupling portion 405 is slightly larger than the outer diameter of the lower part of the sleeve 3. A flange-shaped threaded rod-to-sleeve coupling portion 406 protrudes from the lower end of the threaded rod-to-sleeve coupling portion 405. Threaded rod-to-sleeve coupling portion 405 has two anti-rotation bosses 405e protruding from the outer wall of the threaded rod-to-sleeve coupling portion 405 at symmetrical positions. The outer diameter of the threaded rod-to-sleeve coupling portion 405e is slightly smaller than the outer diameter of the threaded rod-to-sleeve coupling portion 406. The threaded rod-spindle barrel anti-rotation boss 405e is a projection of uniform width that begins at the lower end of the threaded rod-spindle barrel coupling portion 405 and extends upward in the axial direction, with its upper end forming a nose 405d. On both side walls of the threaded rod-spindle barrel engagement boss 405a, other threaded rod-spindle barrel engagement bosses 405a are connected in the circumferential direction. The threaded rod-spindle barrel engagement bosses 405a protrude symmetrically about the threaded rod-spindle barrel anti-rotation boss 405e and have the same outer diameter as the threaded rod-spindle barrel anti-rotation boss 405e. The upper and lower ends of the threaded rod-spindle barrel engagement boss 405a are sloped, with the upper end surface forming an upper slope 405b and the lower end surface forming a lower slope 405c.

[0047] The hakama tube 5 is an exterior member 86 that protects the stick-shaped cosmetic product 1 and the lifting mechanism 82, a fastening member that prevents unintentional separation of the components, and a gripping member during use. The hakama tube 5 is generally pipe-shaped with open top and bottom ends, as shown in the figure. The hakama tube 5 comprises a thin-walled metal outer tube 501 and a thin-walled metal center tube 502. The center tube 502 is inserted into the outer tube 501, and the center tube-outer tube joint 502a of the center tube 502 is joined to the outer tube-center tube joint 501a on the inside surface of the outer tube 501. While the hakama tube 5 is described as being formed from two parts in Example 1, the center tube 502 can also be formed as a single unit. In this case, the center tube 502 would be made of synthetic resin rather than thin metal.

[0048] The upper part of the inner tube 502 protrudes from the upper end of the outer tube 501 to form a hexagonal tube-cap fitting portion 507. A hexagonal tube-sleeve through-hole 509, whose inner diameter is slightly larger than the outer diameter of the upper part of the sleeve 3 and smaller than the outer diameter of the lower part of the sleeve 3, opens at the upper end surface of the hexagonal tube-cap fitting portion 507. The opening edge of the hexagonal tube-sleeve through-hole 509 forms the hexagonal tube-sleeve abutment portion 504. Cap fitting dowels 507a protrude from the peripheral wall of the hexagonal tube-cap fitting portion 507. The cap fitting dowels 507a are evenly spaced at three locations on the peripheral wall of the hexagonal tube-cap fitting portion 507. A stepped hexagonal tube-cap abutment portion 508 with an enlarged outer diameter is provided at the lower end of the hexagonal tube-cap fitting portion 507.

[0049] Below the center tube-outer tube joint 502a of the center tube 502, there is provided a hexagonal tube-threaded rod joint 506, the inner diameter of which is slightly larger than the outer diameter of the threaded rod-hexagonal tube joint 405 of the threaded rod 4 and smaller than the outer diameter of the threaded rod-hexagonal tube abutment 406. The hexagonal tube-threaded rod abutment 505 is formed at the lower end of the center tube 502. There is a slight gap between this hexagonal tube-threaded rod joint 506 and the outer tube 501. A hexagonal tube-threaded rod anti-rotation slot 506a of uniform width is provided in the hexagonal tube-threaded rod joint 506, which starts at the hexagonal tube-threaded rod abutment 505 at the lower end and extends upward in the axial direction, penetrating inward and outward in the shape of a slit. The axial length and width of the hexagon tube-threaded rod anti-rotation slot 506a are slightly longer and wider than the axial length and width of the threaded rod-hexagon tube anti-rotation boss 405e of the threaded rod 4. The hexagon tube-threaded rod engagement holes 506b are formed in the upper end and circumferential side walls of the hexagon tube-threaded rod anti-rotation slot 506a, penetrating inward and outward in a generally T-shaped manner in the left and right circumferential directions. The axial length and width of the hexagon tube-threaded rod engagement holes 506b are slightly longer and wider than the axial length and width of the threaded rod-hexagon tube engagement boss 405a of the threaded rod 4. The lower edge of the hexagon tube-threaded rod engagement hole 506b forms the hexagon tube-threaded rod engagement portion 506c. A mechanism insertion hole 503 is formed through the underside of the outer tube 501. The inner diameter of the mechanism insertion hole 503 is slightly larger than the outer diameter of the threaded rod-to-shank tube abutment portion 406 of the threaded rod 4 .

[0050] The sliding resistor 6 is a resistance member that generates an appropriate sense of resistance when raised or lowered, and is made of a soft elastic material such as rubber or elastomer, and has a generally doughnut shape. The outer diameter of the sliding resistor 6 is slightly larger than the inner diameter of the sleeve-threaded rod sliding surface 305, and the inner diameter is slightly smaller than the outer diameter of the bottom surface of the O-ring groove 403a.

[0051] The cap 7 is an exterior member 86 that protects the stick-shaped cosmetic material 1 and the lifting mechanism 82 when not in use, and is made of thin metal and has a topped cylindrical shape. A cap-hakama tube fitting portion 701 is provided on the inner surface of the lower part of the cap 7. The inner diameter of the cap-hakama tube fitting portion 701 is the same as or slightly smaller than the outer diameter of the cap fitting dowel 507a of the hakama tube 5. The cap 7 forms a cap-hakama tube abutment portion 702 at its lower end.

[0052] Next, the relationship between the components constituting the stick-type cosmetic material feeding container of Example 1 of the present invention will be described with reference to Figures 1 to 3 and 6. First, the lifting mechanism 82 will be described.

[0053] The held portion 102 at the lower end of the stick-shaped cosmetic 1 enters the cosmetic holding portion 201 at the upper end of the holding tube 2, and the cosmetic-holding tube abutment portion 103 abuts against the upper end of the holding tube 2. The cosmetic holding protrusion 201a and the cosmetic holding tongue 201b inside the cosmetic holding portion 201 bite into the held portion 102. The cosmetic holding protrusion 201a and the cosmetic holding tongue 201b engage in an undercut manner with the held portion 102 of the stick-shaped cosmetic 1, and the application portion 101 of the stick-shaped cosmetic 1 protrudes from the upper end of the holding tube 2, connecting them in an undetachable manner.

[0054] The holding tube 2, to which the stick-shaped cosmetic material 1 is connected, is housed within the sleeve 3. The application portion 101 of the stick-shaped cosmetic material 1 and the cosmetic holding portion 201 of the holding tube 2 are in sliding contact with the sleeve-cosmetic material sliding surface 301 of the sleeve 3. The holding tube-sleeve sliding portion 207 of the holding tube 2 is in sliding contact with the sleeve-holding tube sliding surface 307 of the sleeve 3. The holding tube-sleeve guide boss 202 of the holding tube 2 engages with the sleeve-holding tube guide groove 302 of the sleeve 3, allowing the stick-shaped cosmetic material 1 and holding tube 2 to slide up and down within the sleeve 3 without being able to rotate.

[0055] The threaded rod 4 is inserted from the lower end of the sleeve 3 into the lower end of the retaining tube 2 inside the sleeve 3. The drive male screw 401 of the threaded rod 4 is threadedly engaged with the drive female screw 204 of the retaining tube 2. The threaded rod-sleeve sliding contact portion 403 of the threaded rod 4 is in sliding contact with the sleeve-threaded rod sliding surface 305 of the sleeve 3. The threaded rod-sleeve abutment portion 404 of the threaded rod 4 is in abutment with the sleeve-threaded rod abutment portion 306 of the sleeve 3, and the threaded rod-sleeve connection portion 405 and the threaded rod-sleeve abutment portion 406 of the threaded rod 4 protrude from the lower end of the sleeve 3.

[0056] The retaining tube-sleeve abutment portion 203 of the retaining tube 2 abuts against the sleeve inner wall step portion 303 of the sleeve 3, forming a first upper limit position limiting mechanism 8301 that limits the lift of the retaining tube 2. An upper end 204a of the drive female screw 204 of the retaining tube 2 abuts against an upper end 401a of the drive male screw 401 of the threaded rod 4, forming a second upper limit position limiting mechanism 8302 that limits the lift of the retaining tube 2. An upper end 202a of the retaining tube-sleeve guide boss 202 of the retaining tube 2 abuts against an upper end 302a of the sleeve-retaining tube guide groove 302 of the sleeve 3, forming a third upper limit position limiting mechanism 8303 that limits the lift of the retaining tube 2. At least one of the first upper limit position limiting mechanism 8301, the second upper limit position limiting mechanism 8302, and the third upper limit position limiting mechanism 8303 described above constitutes the upper limit position limiting mechanism 83 that limits the lift of the retaining tube 2. Furthermore, the retaining tube-threaded rod abutment portion 206 of the retaining tube 2 abuts against the threaded rod-retaining tube abutment portion 402 of the threaded rod 4, thereby forming a lower limit position limiting mechanism 84 that restricts the lowering of the retaining tube 2.

[0057] The sliding resistor 6 is fitted into the O-ring groove 403a of the threaded rod 4. The outer peripheral wall of the sliding resistor 6 elastically abuts against the sleeve-threaded rod sliding surface 305 of the sleeve 3.

[0058] Next, we will explain the exterior member 86. The hakama tube 5 of the exterior member 86 is formed by joining the center tube-outer tube joint 502a of the center tube 502 and the outer tube-center tube joint 501a of the outer tube 501 in a non-rotatable and non-detachable manner.

[0059] The lifting mechanism 82 is inserted through the mechanism insertion hole 503 at the lower end of the helical tube 5, and the tip of the sleeve 3 protrudes upward from the helical tube-sleeve through-hole 509. The threaded rod-helical tube abutment portion 406 of the lifting mechanism 82 abuts against the helical tube-helical tube abutment portion 505 of the helical tube 5, preventing the threaded rod 4 of the lifting mechanism 82 from coming off upward. The threaded rod-helical tube anti-rotation boss 405e of the threaded rod 4 engages with the helical tube-helical tube anti-rotation slot 506a of the helical tube 5, and the threaded rod-helical tube engagement boss 405a engages with the helical tube-helical tube engagement portion 506c, respectively, so that the helical tube 5 and the threaded rod 4 of the lifting mechanism 82 are non-rotatably but detachably connected. At this time, the female drive screw 204 of the holding tube 2 of the lifting mechanism 82 is threadedly engaged with the male drive screw 401 of the threaded rod 4. The sleeve 3 of the lifting mechanism 82 is rotatably clamped with the sleeve-to-screw tube abutment portion 304 abutting against the spine tube-sleeve abutment portion 504 of the spine tube 5 and the sleeve-to-screw abutment portion 306 abutting against the threaded rod-to-sleeve abutment portion 404 of the threaded rod 4. As described above, the spine tube 5 and the lifting mechanism 82 are detachably connected.

[0060] The cap 7 of the exterior member 86 is detachably fitted to the hakama tube-cap fitting portion 507 of the hakama tube 5 at the cap-hakama tube fitting portion 701, and the cap-hakama tube abutment portion 702 abuts against the hakama tube-cap abutment portion 508. When the cap 7 is fitted to the hakama tube 5, it covers the sleeve 3 of the lifting mechanism 82 that protrudes from the hakama tube-sleeve through-hole 509, thereby protecting the stick-shaped cosmetic material 1 inside the exterior member 86 and the lifting mechanism 82.

[0061] 5 and 6, in the first embodiment of the present invention, the cap fitting dowel 507a is protruded from the cap fitting portion 507 of the cap sleeve 5. A slight interference between the outer diameter of the cap fitting dowel 507a and the inner diameter of the cap-cap fitting portion 701 of the cap 7 generates frictional resistance between the cap sleeve 5 and the cap 7, forming a cap fitting and holding mechanism 85 that detachably fits and holds the cap 7 on the cap sleeve 5. The cap fitting and holding mechanism 85 can be implemented not only by the interference of the cap fitting dowel 507a but also by undercut engagement or magnetic attraction. The fitting portion of the cap 7 may be the cap fitting portion not only to the cap fitting portion 507 of the cap sleeve 5 but also to the upper part of the sleeve 3. In this case, the sleeve 3 moves along with the cap 7 due to the fitting force of the cap 7, and it is necessary to provide a rotation stopper between the cap 7 and the hakama tube 5 so that the lifting mechanism 82 does not operate while the cap 7 is fitted. Furthermore, instead of fitting the cap 7 so that it can be removed, a shutter-shaped cap may be attached to the hakama tube 5 so that the cap can be opened and closed freely.

[0062] Next, a method for assembling the components of the stick-type cosmetic material feeding container of Example 1 of the present invention will be described with reference to FIG.

[0063] First, the sliding resistor 6 is combined with the threaded rod 4. The upper part of the threaded rod 4 is inserted into the roughly doughnut-shaped ring of the sliding resistor 6. The outer diameter of the threaded rod-sleeve sliding contact portion 403 of the threaded rod 4 is larger than the inner diameter of the sliding resistor 6, causing interference and preventing insertion into the sliding resistor 6. However, because the sliding resistor 6 is made of a soft material with elasticity, tension is applied to the sliding resistor 6 to expand its diameter, and the sliding resistor 6 is fitted into the O-ring groove 403a of the threaded rod-sleeve sliding contact portion 403. Because the groove diameter of the O-ring groove 403a is slightly larger than the inner diameter of the sliding resistor 6, the sliding resistor 6 is fitted into the O-ring groove 403a under tension.

[0064] The retaining tube 2 is combined with the threaded rod 4 combined with the sliding resistor 6. When the upper end of the threaded rod 4 is inserted into the lower end of the retaining tube 2, the upper end of the threaded rod 4 abuts against the lower end of the retaining tube 2 because the drive female screw 204 is not threaded at the upper end of the threaded rod 4 and the outer diameter is larger than the inner diameter of the drive female screw 204. From this state in which the threaded rod 4 abuts against the retaining tube 2, the threaded rod 4 is further pushed in. The lower end of the retaining tube 2 is provided with the retaining tube deformation slit 205, and the lower end of the retaining tube 2 is able to expand in the radial direction, so the threaded rod 4 pushes open the lower end of the retaining tube 2, the tip of the threaded rod 4 climbs over the drive female screw 204 of the retaining tube 2, and the drive female screw 204 and the drive male screw 401 of the retaining tube 2 threadably engage with each other. As the threaded rod 4 continues to be pushed in, the drive female screw 204 expands, climbs over the drive male screw 401, and screws in again. This climbing and screwing is repeated, producing a clicking sound, and the retaining tube-threaded rod abutment portion 206 abuts against the threaded rod-retaining tube abutment portion 402, moving to a position where the retaining tube 2 will not descend any further (the activation position of the lower limit position limiting mechanism 84). As a result, the threaded rod-sleeve sliding portion 403 and the threaded rod-shaft tube abutment portion 406 of the threaded rod 4 protrude from the lower end of the retaining tube 2.

[0065] The sleeve 3 is combined with this composite formed of the retaining tube 2, the sliding resistor 6, and the threaded rod 4 to form the lifting mechanism 82. When the composite formed of the retaining tube 2, the sliding resistor 6, and the threaded rod 4 is in the operating position of the lower limit position limiting mechanism 84 of the retaining tube 2 (a position where the retaining tube-threaded rod abutment portion 206 abuts against the threaded rod-retaining tube abutment portion 402 and the retaining tube 2 does not descend any further), the cosmetic holding portion 201 at the upper end of the retaining tube 2 is inserted from the lower end of the sleeve 3, and the sleeve-threaded rod abutment portion 306 at the lower end of the sleeve 3 abuts against the threaded rod-sleeve abutment portion 404 of the threaded rod 4. At this time, the cosmetic holding portion 201 of the retaining tube 2 is positioned on the sleeve-cosmetic sliding surface 301 of the sleeve 3, the retaining tube-sleeve sliding portion 207 is positioned on the sleeve-retaining tube sliding surface 307, and the threaded rod-sleeve sliding portion 403 of the threaded rod 4 is positioned on the sleeve-threaded rod sliding surface 305. The retaining tube-sleeve guide boss 202 of the retaining tube 2 engages with the sleeve-retaining tube guide groove 302 of the sleeve 3, making the retaining tube 2 non-rotatable but slidable up and down within the sleeve 3. The sliding resistor 6 elastically slides against the sleeve-threaded rod sliding surface 305 of the sleeve 3, generating sliding resistance when the threaded rod 4 and the sleeve 3 rotate relative to each other. The retaining tube-sleeve sliding portion 207 of the retaining tube 2 is in sliding contact with the sleeve-retaining tube sliding surface 307 of the sleeve 3, and deformation of the retaining tube-sleeve sliding portion 207 due to the retaining tube deformation slit 205 is suppressed, making it impossible for the driving female screw 204 of the retaining tube 2 to go over the driving male screw 401 of the threaded rod 4, and for the retaining tube 2 and the threaded rod 4 to separate.

[0066] In addition, the circumferential engagement position of the sleeve 3 and the retaining tube 2 can be set by making the circumferential arrangement of the sleeve-retaining tube guide groove 302 of the sleeve 3 uneven, or by making the groove width of the sleeve-retaining tube guide groove 302 uneven, and by making the retaining tube-sleeve guide boss 202 of the retaining tube 2 correspond to the sleeve-retaining tube guide groove 302.

[0067] The center tube 502 and the outer tube 501 are combined to form the Hakama tube 5. The lower part of the center tube 502 is inserted from the top of the outer tube 501, and the center tube-outer tube joint 502a on the outer surface of the center tube 502 is joined to the outer tube-center tube joint 501a on the inner surface of the outer tube 501. This composite of the center tube 502 and the outer tube 501 becomes the Hakama tube 5. The center tube 502 and the outer tube 501 may be joined by any one of press-fitting, bonding, adhesion, and welding, or a combination of these, or by a different method. However, if the center tube-outer tube joint 502a and the outer tube-center tube joint 501a are joined by a method that does not allow for disassembly, such as bonding or welding, it is desirable to use the same material for the outer tube 501 and the center tube 502, or a combination of materials that do not require separation, in consideration of recyclability.

[0068] The sheath tube 5 and the lifting mechanism 82 are combined to form the container body 81. The tip of the sleeve 3 of the lifting mechanism 82 is inserted through the mechanism insertion hole 503 on the underside of the sheath tube 5, and the nose 405d at the upper end of the threaded rod-sheath tube anti-rotation boss 405e of the threaded rod 4 abuts against the sheath tube-threaded rod abutment portion 505 of the sheath tube 5. In this state, the lifting mechanism 82 is rotated, and the nose 405d of the threaded rod-sheath tube anti-rotation boss 405e engages with the sheath tube-threaded rod anti-rotation slot 506a of the sheath tube 5. As a result, the threaded rod 4 of the lifting mechanism 82 and the sheath tube 5 are unable to rotate relative to each other. When the lifting mechanism 82 is inserted in this state, the upper slope 405b of the threaded rod-Hokage tube engagement boss 405a of the lifting mechanism 82 abuts against the Hokage tube-threaded rod abutment portion 505 of the Hokage tube 5. When the lifting mechanism 82 is further pushed in in this state, the upper slope 405b of the threaded rod-Hokage tube engagement boss 405a pushes apart the Hokage tube-threaded rod joint portion 506 of the Hokage tube 5 by wedge action, and the threaded rod-Hokage tube engagement boss 405a of the threaded rod 4 slips inside the Hokage tube-threaded rod joint portion 506 of the Hokage tube 5 and engages with the Hokage tube-threaded rod engagement hole 506b. At the same time, the lower slope 405c of the threaded rod-screw rod engagement boss 405a of the threaded rod 4 engages with the screw rod-screw rod engagement portion 506c of the screw rod 5, and the screw rod 5 and the lifting mechanism 82 are combined. At this time, the sleeve 3 of the lifting mechanism 82 protrudes upward from the screw rod-sleeve through hole 509 of the screw rod 5.

[0069] When the nose 405d of the threaded rod-to-shank tube anti-rotation boss 405e of the threaded rod 4 engages with the shank tube-to-threaded rod anti-rotation slot 506a of the shank tube 5, the shank tube 5 and the threaded rod 4 can be aligned in the circumferential direction. In other words, the shank tube 5 and the lifting mechanism 82 can be assembled with their circumferential positions aligned.

[0070] The stick-type cosmetic material 1 is attached to the container body 81. The method for attaching the stick-type cosmetic material 1 will be explained below with reference to Fig. 4. The method for attaching the stick-type cosmetic material 1 in Example 1 of the present invention is a "container filling molding method for cosmetics."

[0071] When the holding tube 2 of the container body 81 is in the operating position of the lower limit position limiting mechanism 84 (a position where the holding tube-threaded rod abutment portion 206 of the holding tube 2 abuts the threaded rod-holding tube abutment portion 402 of the threaded rod 4), the cosmetic material 11 melted by heating is poured into the sleeve 3 from the upper end of the sleeve 3. The melted cosmetic material 11 fills the space surrounded by the cosmetic material holding portion 201 of the holding tube 2 and the sleeve-cosmetic sliding surface 301 of the sleeve 3. After the molten cosmetic material 11 is filled, it is cooled and solidified into a shape surrounded by the cosmetic material holding portion 201 and the sleeve-cosmetic sliding surface 301, forming the stick-shaped cosmetic material 1 inside the container body 81. The portion of the stick-shaped cosmetic material 1 formed by the sleeve-cosmetic sliding surface 301 of the sleeve 3 conforms to the shape of the upper end surface, which was the filling port for the molten cosmetic material 11, and becomes the application portion 101. Furthermore, the portion of the holding tube 2 formed by the cosmetic holding portion 201 becomes the held portion 102, and a stepped cosmetic-holding tube abutment portion 103 is formed at the upper end of this held portion 102. The cosmetic holding protrusion 201a and cosmetic holding tongue 201b of the cosmetic holding portion 201 are inserted into the held portion 102 in an undercut manner, so that the stick-shaped cosmetic 1 does not come out of the holding tube 2.

[0072] The above has described the "cosmetic container filling and molding method" for fitting the stick-type cosmetic material 1. As a method for solidifying the cosmetic material after filling it in a fluid state, the method described above involves heating the cosmetic material to melt it and make it fluid, and then cooling it to solidify it. In addition to this method, it is also possible to mix a volatile liquid such as water or alcohol with the cosmetic material to make it fluid, and then volatilize the liquid component to solidify it.

[0073] The container body 81 containing the stick-shaped cosmetic material 1 is fitted and combined with the cap 7 to form a stick-shaped cosmetic material feeding container that protects the application part 101 of the stick-shaped cosmetic material 1.

[0074] Next, a method of using the stick-type cosmetic material feeding container of Example 1 of the present invention will be described with reference to the drawings. First, the operating procedure for applying the stick-type cosmetic material 1 will be described with reference to Figures 1 to 3. The retaining tube 2 in the container body 81 has the retaining tube-threaded rod abutment portion 204a abutting against the threaded rod-retaining tube abutment portion 401a of the threaded rod 4, and the lower limit position limiting mechanism 84 is activated. The stick-type cosmetic material 1 is contained in the sleeve 3. The cap 7 is fitted into the cap-to-cap fitting portion 507 of the container body 81, and the sleeve 3 of the container body 81 is housed within the cap 7 (see Figures 1 and 2).

[0075] Here, when the cap 7 fitted into the hakama tube-cap fitting portion 507 is pulled out, the hakama tube-cap fitting portion 507 is disengaged, the cap 7 is separated from the container body 81, and the sleeve 3 of the container body 81 is exposed. By rotating the exposed sleeve 3 and the hakama tube 5 relative to each other, the lifting mechanism 82 is activated and the stick-shaped cosmetic material 1 is raised and lowered. The direction of rotation at this time differs depending on whether the sleeve 3 or the hakama tube 5 is the fixed side. In the following explanation, details will be given assuming that the sleeve 3 is the fixed side. When the hakama tube 5 is rotated counterclockwise while the sleeve 3 is held (fixed), the holding tube 2 does not rotate together with the sleeve 3 and is held because the holding tube-sleeve guide boss 202 is non-rotatably but vertically slidably engaged with the sleeve-holding tube guide groove 302 of the sleeve 3. Because the threaded rod-to-screw barrel anti-rotation boss 405e of the threaded rod 4 is non-rotatably engaged with the screw barrel-to-screw rod anti-rotation slot 506a of the screw barrel 5, the threaded rod 4 rotates counterclockwise in response to the screw barrel 5. As a result, the drive female screw 204 of the holding barrel 2, which is not rotated by the sleeve 3, is threadedly engaged with the drive male screw 401 of the threaded rod 4, which is rotated counterclockwise by the screw barrel 5, and the holding barrel 2 moves up and down due to the threading action. In Example 1 of the present invention, because the drive female screw 204 and the drive male screw 401 are left-handed threads, the holding barrel 2 moves upward. As the holding barrel 2 rises, the stick-shaped cosmetic material 1 held by the holding barrel 2 also moves up, and the tip of the application portion 101 of the stick-shaped cosmetic material 1 protrudes from the top of the sleeve 3.

[0076] The tip of the protruding application portion 101 of the stick-shaped cosmetic 1 is used to apply the cosmetic to the desired area, such as the lips. Note that, although Fig. 3 shows the stick-shaped cosmetic 1 with the holding tube 2 raised to its upper limit position, in practice, the application portion 101 of the stick-shaped cosmetic 1 is protruded the minimum amount necessary from the tip of the sleeve 3 for application.

[0077] The procedure for storing the stick-type cosmetic material 1 protruding from the container body 81 is as follows. When the sleeve 3 is held (fixed) and the hakama tube 5 is rotated clockwise, the holding tube 2 is held without rotating together with the sleeve 3 because the holding tube-sleeve guide boss 202 is non-rotatably but vertically slidably engaged with the sleeve-holding tube guide groove 302 of the sleeve 3. The threaded rod-hakama tube anti-rotation boss 405e of the threaded rod 4 is non-rotatably engaged with the hakama tube-threaded rod anti-rotation slot 506a of the hakama tube 5, so the threaded rod 4 rotates clockwise in response to the hakama tube 5. As a result, the drive female screw 204 of the holding tube 2, which does not rotate due to the sleeve 3, is threadedly engaged with the drive male screw 401 of the threaded rod 4, which rotates clockwise due to the hakama tube 5, and the holding tube 2 is lowered due to the threaded engagement action. As the holding tube 2 descends, the stick-shaped cosmetic material 1 held by the holding tube 2 also descends, and the tip of the application part 101 of the stick-shaped cosmetic material 1 is housed within the sleeve 3. After the stick-shaped cosmetic material 1 is completely housed within the sleeve 3, the cap 7 is fitted into the cap-tube fitting part 507 of the container body 81, and the sleeve 3 of the container body 81 is housed within the cap 7.

[0078] In order to prevent damage caused by excessive load, the lifting mechanism 82 is provided with an upper limit position limiting mechanism 83 and a lower limit position limiting mechanism 84, which the holding barrel 2 comes into contact with to physically limit the upward and downward movement of the holding barrel 2. Of these, the upper limit position limiting mechanism 83 is adapted to be brought into contact with the holding barrel 2 to limit the upward movement of the holding barrel 2. The lower limit position limiting mechanism 84 includes a first upper limit position limiting mechanism 8301 in which the retaining tube-sleeve abutment portion 203 at the upper end of the retaining tube-sleeve sliding portion 207 of the retaining tube 2 abuts against the sleeve inner wall step portion 303 of the sleeve 3, a second upper limit position limiting mechanism 8302 in which the upper end 204a of the drive female screw 204 of the retaining tube 2 abuts against the upper end 401a of the drive male screw 401 of the threaded rod 4, and a third upper limit position limiting mechanism 8303 in which the upper end 202a of the retaining tube-sleeve guide boss 202 of the retaining tube 2 abuts against the upper end 302a of the sleeve-retaining tube guide groove 302 of the sleeve 3, and at least one of these is used. 1 and 2, the lower limit position limiting mechanism 84 limits the descent of the retaining tube 2 by abutting the retaining tube-threaded rod abutment portion 206 of the retaining tube 2 with the threaded rod-retaining tube abutment portion 402 of the threaded rod 4.

[0079] In the first embodiment of the present invention, as shown in Fig. 3, the upper limit positions of the first upper limit position limit mechanism 8301 and the second upper limit position limit mechanism 8302 are aligned, and these two mechanisms are combined to form the upper limit position limit mechanism 83. The third upper limit position limit mechanism 8303 has a small engagement between the sleeve-retaining tube guide groove 302 and the retaining tube-sleeve guide boss 202, and there is a risk that the engagement will be disengaged if excessive rotational torque is applied. For this reason, the third upper limit position limit mechanism 8303 is located above the first upper limit position limit mechanism 8301 and the second upper limit position limit mechanism 8302, thereby disabling its function.

[0080] The disassembly procedure for disposing of a used stick-type cosmetic material feeding container according to Example 1 of the present invention will be described with reference to Figure 5. When the sleeve 3 is pressed downward while the spool tube 5 of the used container body 81 is held (fixed), the sleeve-threaded rod abutment portion 306 abuts the threaded rod-sleeve abutment portion 404, and therefore the threaded rod 4 is also pressed downward via the sleeve 3. This downward pressing force acting on the threaded rod 4 acts on the engagement portion of the threaded rod-threaded rod engagement boss 405a. In other words, the lower slope 405c of the threaded rod-threaded rod engagement boss 405a is engaged with the spool tube-threaded rod engagement portion 506c, and the downward pressing force presses down the lower slope 405c. The lower slope 405c acts as a wedge to push apart the helical tube-threaded rod joint 506 and slip inside the helical tube-threaded rod joint 506, thereby disengaging the helical tube-threaded rod engagement portion 506c from the threaded rod-helical tube engagement boss 405a. The threaded rod-helical tube joint 405 of the threaded rod 4 protrudes from the lower end of the helical tube 5, and the lifting mechanism 82 can be removed from the helical tube 5 by pinching this threaded rod-helical tube joint 405.

[0081] The sleeve 3 and the threaded rod 4 of the removed lifting mechanism 82 are combined only by the elasticity of the sliding resistor 6, so by holding (fixing) the sleeve 3 and pulling out the threaded rod 4, it can be disassembled into two parts: the sleeve 3 and a composite made up of the retaining tube 2, the threaded rod 4, and the sliding resistor 6. This composite made up of the retaining tube 2, the threaded rod 4, and the sliding resistor 6 is no longer held down by the sleeve 3, and the retaining tube-sleeve sliding contact portion 207 of the retaining tube 2 can deform radially due to the retaining tube deformation slits 205. When the threaded rod 4 is pulled out while the retaining tube 2 is held (fixed) in this composite consisting of the retaining tube 2, the threaded rod 4, and the sliding resistor 6, the retaining tube-sleeve sliding contact portion 207 at the lower end of the retaining tube 2 is deformed radially by the retaining tube deformation slit 205, and the male drive thread 401 of the threaded rod 4 and the female drive thread 204 of the retaining tube 2 overcome each other while making a clicking sound and repeatedly screw together, releasing the screwed state between the retaining tube 2 and the threaded rod 4, allowing the composite to be disassembled into the retaining tube 2, the threaded rod 4, and the sliding resistor 6. Because the sliding resistor 6 is fitted into the O-ring groove 403a of the threaded rod 4, the threaded rod 4 can be disassembled into the threaded rod 4 and the sliding resistor 6 by applying tension to the sliding resistor 6 to expand its diameter and pulling it out. As a result, the lifting mechanism 82 can be disassembled into its individual components for disposal, as shown in FIG. 6 .

[0082] The actions and effects brought about by the stick-type cosmetic material dispensing container of Example 1 of the present invention will now be described.

[0083] In the stick-type cosmetic dispensing container of Example 1 of the present invention, the female drive screw 204 and the male drive screw 401 that raise and lower the stick-type cosmetic 1 are positioned below the cosmetic holding portion 201 of the holding tube 2, and the sleeve-to-cosmetic sliding surface 301 of the sleeve 3 that contains the stick-type cosmetic 1 is smooth, so that the stick-type cosmetic 1 can be attached using the ``cosmetic in-container filling and molding method.''

[0084] In the stick-type cosmetic material dispensing container of Example 1 of the present invention, the lifting mechanism 82 can be assembled by pushing the drive female screw 204 and the drive male screw 401 in without rotating them, and other members can also be assembled by inserting them from below. Furthermore, the exterior member 86 and the lifting mechanism 82 can also be assembled by inserting the lifting mechanism 82 from below the hakama tube 5. Therefore, the assembly work is simple and easy, and can be done from one direction, making it easy to automate assembly.

[0085] In the configuration of the stick type cosmetic material dispensing container of Example 1 of the present invention, the engagement between the sheath tube 5 and the threaded rod 4 is released by pushing down the sleeve 3, and the container can be disassembled into the exterior member 86 and the lifting mechanism 82. The lifting mechanism 82 can be easily disassembled into each of the components, namely the retaining tube 2, the sleeve 3, the threaded rod 4, the sheath tube 5, and the sliding resistor 6. Therefore, even if the components of the stick type cosmetic material dispensing container of Example 1 of the present invention are not made of the same material, and appropriate materials are selected for each component, the container can be disassembled into individual components, allowing them to be disposed of and recycled separately for each material.

[0086] In the configuration of the stick type cosmetic material dispensing container of Example 1 of the present invention, the range of vertical sliding of the holding tube 2 is restricted by the lower limit position limiting mechanism 84 and the upper limit position limiting mechanism 83. As a result, even if the holding tube 2 is further raised or lowered when it is in the upper limit position or the lower limit position, no separating stress is applied to the engagement portion between the exterior member 86 and the lifting mechanism 82, i.e., the joint portion between the hakama tube-threaded rod joint 506 of the hakama tube 5 and the threaded rod-hakama tube joint 405 of the threaded rod 4. Therefore, the joining force between the exterior member 86 and the lifting mechanism 82 need only be set to a level that prevents unintentional separation when the stick type cosmetic material dispensing container is in use, and the force required to press on the sleeve 3 when disassembling the container does not need to be extremely strong and can be set to a level that allows easy disassembly.

[0087] The O-ring-shaped sliding resistor 6 is sandwiched between the sleeve 3 and the threaded rod 4, and generates sliding resistance when the sleeve 3 and the threaded rod 4 rotate relative to each other, but there is no functional problem if the sliding resistor 6 is not present. However, while the absence of the sliding resistor 6 reduces parts and costs, it also leads to a decrease in container quality, such as the occurrence of rattles between the components of the lifting mechanism 82 and a stale feel when dispensing. Therefore, whether or not to include the sliding resistor 6 is selected by comparing the advantages and disadvantages described above.

[0088] Next, a stick-type cosmetic dispensing container according to Example 2 of the present invention will be described with reference to Figures 8 to 11. The stick-type cosmetic dispensing container according to Example 2 of the present invention is one variation of the stick-type cosmetic dispensing container according to Example 1 of the present invention. The stick-type cosmetic dispensing containers according to Examples 1 and 2 of the present invention differ in the shapes of the hakama tube-threaded rod connecting portion 506 of the hakama tube 5 and the threaded rod-hakama tube connecting portion 405 of the lifting mechanism 82, and therefore differ in the portions that deform when the lifting mechanism 82 is attached or detached.

[0089] Specifically, as shown in Fig. 6, the stick-type cosmetic material dispensing container of Example 1 of the present invention has a stopper tube-threaded rod anti-rotation slot 506a provided at the lower end of the slat tube 5 (the inner tube 502), allowing the slat tube-threaded rod joint 506 to expand in the circumferential direction. As shown in Fig. 5, the threaded rod-to-slat tube engagement boss 405a slides inside the slat tube-threaded rod joint 506, releasing the engagement between the slat tube 5 and the lifting mechanism 82. In contrast, as shown in Fig. 11, the stick-type cosmetic material dispensing container of Example 2 of the present invention has a bridge portion 506d provided at the slat tube-threaded rod joint 506, preventing the slat tube-threaded rod joint 506 from expanding, and a threaded rod deformation slit 407 provided at the lower end of the threaded rod 4, allowing the threaded rod-to-slat tube joint 405 of the threaded rod 4 to contract in the circumferential direction. 10, an upper threaded rod-Hokage tube boss 405g, which will be described later, slides into the inside of the Hokage tube-threaded rod joint 506 of the Hokage tube 5, thereby releasing the engagement of the lifting mechanism 82.

[0090] The rod-type cosmetic material dispensing container of Example 2 of the present invention will be described in detail below, with only the differences from the rod-type cosmetic material dispensing container of Example 1 of the present invention already described being described with reference to Figures 8 and 9. An upper threaded rod-to-spindle barrel boss 405g and a lower threaded rod-to-spindle barrel boss 405h are protruding from two symmetrical positions on the peripheral wall of the threaded rod-to-spindle barrel coupling portion 405 of the threaded rod 4 of the lifting mechanism 82, one above the other in the axial direction, with a bridge relief portion 405f formed therebetween. The upper threaded rod-to-spindle barrel boss 405g has a generally convex planar shape, with portions extending to the left and right in the circumferential direction forming threaded rod-to-spindle barrel engagement bosses 405a and a portion extending upward in the axial direction forming a nose 405d. The lower threaded rod-to-spindle barrel boss 405h has a generally rectangular shape whose lower end begins at the threaded rod-to-spindle barrel abutment portion 406. The circumferential width of the nose 405d of the upper threaded rod-Hokkama tube boss 405g is the same as the circumferential width of the lower threaded rod-Hokkama tube boss 405h. The upper axial surface of the threaded rod-Hokkama tube engagement boss 405a forms an inclined upper slope 405b, and the lower axial surface forms an inclined lower slope 405c.

[0091] Threaded rod deformation slits 407 are provided penetrating from the inside to the outside at two intermediate positions in the circumferential direction of the threaded rod-Hokkama tube coupling portion 405 of the upper threaded rod-Hokkama tube boss 405g and the lower threaded rod-Hokkama tube boss 405h. The threaded rod deformation slits 407 are provided at two symmetrical positions in the circumferential direction, with their upper ends located above the upper threaded rod-Hokkama tube boss 405g, dividing the threaded rod-Hokkama tube abutment portion 406, and reaching the lower end of the threaded rod 4.

[0092] A hakama tube-threaded rod engagement hole 506b, a hakama tube-threaded rod positioning slot 506e, and a bridge portion 506d are provided on the side wall of the hakama tube-threaded rod connection portion 506 of the hakama tube 5 at two positions opposite to the upper threaded rod-hakama tube boss 405g, the lower threaded rod-hakama tube boss 405h, and the bridge relief portion 405f of the threaded rod-hakama tube connection portion 405 of the threaded rod 4.

[0093] The helical tube-threaded rod engagement hole 506b penetrates the helical tube-threaded rod coupling portion 506 and has a generally convex shape that is slightly larger than the planar shape of the upper threaded rod-helical tube boss 405g of the threaded rod 4. The portion of the helical tube-threaded rod engagement hole 506b facing the nose 405d of the threaded rod 4 becomes a nose engagement portion 506f with which the nose 405d engages, and the portion of the threaded rod 4 facing the threaded rod-helical tube engagement boss 405a becomes an engagement boss engagement portion 506g with which the threaded rod-helical tube engagement boss 405a engages. The bottom of the engagement boss engagement portion 506g becomes a helical tube-threaded rod engagement portion 506c that abuts and engages with the lower slope 405c of the threaded rod-helical tube engagement boss 405a.

[0094] The hexagonal tube-threaded rod positioning slot 506e has the same generally rectangular shape as the lower threaded rod-hexagonal tube boss 405h, and its lower end starts from the hexagonal tube-threaded rod abutment portion 505 at the lower end of the hexagonal tube 5. The circumferential width of the hexagonal tube-threaded rod positioning slot 506e is slightly wider than the circumferential width of the nose 405d of the upper threaded rod-hexagonal tube boss 405g of the threaded rod 4. The axial length of the hexagonal tube-threaded rod positioning slot 506e is longer than the axial length of the nose 405d of the upper threaded rod-hexagonal tube boss 405g. As a result, when the nose 405d of the upper threaded rod-Hakama tube boss 405g engages with the Hakama tube-threaded rod positioning slot 506e, the upper slope 405b of the upper threaded rod-Hakama tube boss 405g abuts against the Hakama tube-threaded rod abutment portion 505 of the Hakama tube 5 before the upper end of the nose 405d abuts against the upper end of the Hakama tube-threaded rod positioning slot 506e.

[0095] Next, a method for assembling the stick-type cosmetic material dispensing container of Example 2 of the present invention will be described. Note that explanations that overlap with the method for assembling the stick-type cosmetic material dispensing container of Example 1 of the present invention will be omitted, and differences, specifically, a method for combining the lifting mechanism 82 and the hakama tube 5 of the exterior member 86, will be described with reference to Figure 11.

[0096] The tip of the sleeve 3 of the lifting mechanism 82 is inserted through the mechanism insertion hole 503 on the underside of the helical tube 5, and the nose 405d at the upper end of the upper threaded rod-helical tube boss 405g of the threaded rod 4 abuts against the helical tube-threaded rod abutment portion 505 of the helical tube 5. In this state, the lifting mechanism 82 is rotated, and the nose 405d of the upper threaded rod-helical tube boss 405g is engaged with the helical tube-threaded rod positioning slot 506e of the helical tube 5. As a result, the threaded rod 4 of the lifting mechanism 82 and the helical tube 5 become unable to rotate relative to each other, and at the same time, the upper slope 405b of the threaded rod-helical tube engagement boss 405a of the upper threaded rod-helical tube boss 405g abuts against the helical tube-threaded rod abutment portion 505 of the helical tube 5.

[0097] If the lifting mechanism 82 is further pushed in the axial direction in this state, the wedge action of the upper slope 405b causes the threaded rod-Hokage tube joint 405 to narrow inward, and the upper threaded rod-Hokage tube boss 405g slides inside the Hokage tube-threaded rod joint 506. The upper threaded rod-Hokage tube boss 405g passes through the bridge portion 506d of the Hokage tube 5 and reaches and engages with the Hokage tube-threaded rod engagement hole 506b. At the same time, the lower threaded rod-Hokage tube boss 405h of the threaded rod 4 engages with the Hokage tube-threaded rod positioning slot 506e of the Hokage tube 5, the bridge relief portion 405f engages with the bridge portion 506d, and the threaded rod-Hokage tube abutment portion 406 and the Hokage tube-threaded rod abutment portion 505 come into contact. As a result, the sleeve 3 of the lifting mechanism 82 protrudes above the hakama tube 5 through the hakama tube-sleeve through-hole 509, and the hakama tube 5 and the threaded rod 4 of the lifting mechanism 82 are joined together so as not to rotate or be removed (see FIGS. 8 and 9). In this way, the lifting mechanism 82 and the hakama tube 5 are combined. This combined body is the container body 81 (see FIG. 10).

[0098] Next, a method of using the stick type cosmetic material dispensing container of Example 2 of the present invention will be described. Note that explanations that overlap with the method of using the stick type cosmetic material dispensing container of Example 1 of the present invention will be omitted, and differences will be described, specifically, the procedure for removing the lifting mechanism 82 as part of the disassembly procedure for disposing of a used stick type cosmetic material dispensing container, with reference to Figure 10.

[0099] The blade tube 5 of the container body 81 of the used stick-type cosmetic material feeding container is held (fixed), and the sleeve 3 of the lifting mechanism 82 is pushed downward. The sleeve 3 presses the threaded rod 4 downward because the sleeve-threaded rod abutment portion 306 abuts against the threaded rod-sleeve abutment portion 404. This downward pressing force acts between the engagement portion of the upper threaded rod-blade tube boss 405g of the threaded rod 4 and the blade tube-blade tube engagement portion 506c of the blade tube 5, that is, between the lower slope 405c of the upper threaded rod-blade tube boss 405g and the blade tube-blade tube engagement portion 506c of the blade tube-blade tube engagement hole 506b. Due to the wedge action of the lower slope 405c, the threaded rod-Hakama tube joint 405 of the threaded rod 4 narrows inward, and the upper threaded rod-Hakama tube boss 405g slides inside the Hakama tube-threaded rod joint 506 of the Hakama tube 5. As a result, the upper threaded rod-Hakama tube boss 405g and the Hakama tube-threaded rod engagement part 506c are disengaged, and the threaded rod-Hakama tube joint 405 of the threaded rod 4 and the threaded rod-Hakama tube abutment part 406 protrude from the mechanism part insertion hole 503 on the underside of the Hakama tube 5, and the lifting mechanism 82 can be removed from the Hakama tube 5 of the exterior member 86.

[0100] When a new lifting mechanism 82 is attached to the exterior member 86, the tip of the sleeve 3 of the lifting mechanism 82 is inserted through the mechanism insertion hole 503 on the underside of the helical tube 5 of the exterior member 86. The nose 405d of the upper threaded rod-helical tube boss 405g of the threaded rod 4 engages with the helical tube-threaded rod positioning slot 506e of the helical tube 5, thereby positioning the helical tube 5 and the lifting mechanism 82 in the circumferential direction. After positioning the lifting mechanism 82 in the circumferential direction, the lifting mechanism 82 is pushed into the helical tube 5, and the upper threaded rod-helical tube boss 405g of the threaded rod 4 removably engages with the helical tube-threaded rod engagement hole 506b of the helical tube 5, thereby combining the helical tube 5 and the lifting mechanism 82.

[0101] Next, the effects of the stick-type cosmetic material dispensing container of Example 2 of the present invention will be explained in comparison with the stick-type cosmetic material dispensing container of Example 1 of the present invention. In the case of Example 1 of the present invention, as shown in Fig. 6, a slit-shaped anti-rotation slot 506a for the screw tube-threaded rod joint 506 of the screw tube 5 is provided, thereby imparting circumferential elasticity to the screw tube-threaded rod joint 506. In the case of Example 2 of the present invention, as shown in Fig. 11, a screw rod deformation slit 407 is provided in the screw rod-threaded rod joint 405 of the screw rod 4 of the lifting mechanism 82, thereby imparting circumferential elasticity to the screw rod-threaded rod joint 405.

[0102] The helical tube-threaded rod positioning slot 506e is provided in the helical tube-threaded rod coupling portion 506 of the helical tube 5, and the nose 405d of the upper threaded rod-helical tube boss 405g of the threaded rod 4 is engaged therewith, thereby circumferentially aligning the helical tube 5 with the threaded rod 4 of the lifting mechanism 82. Even if the helical tube-threaded rod positioning slot 506e is not provided, the helical tube 5 can be connected to the exterior member 86 by visually aligning the helical tube 5 with the lifting mechanism 82 in the circumferential direction and engaging the helical tube-threaded rod engagement hole 506b of the helical tube 5 with the upper threaded rod-helical tube boss 405g of the threaded rod 4 of the lifting mechanism 82.

[0103] Furthermore, the engagement between the helical tube-threaded rod engaging portion 506c and the upper threaded rod-helical tube boss 405g not only detachably connects the helical tube 5 and the lifting mechanism 82, but also connects them non-rotatably in the circumferential direction. In other words, even if the threaded rod 4 does not have the lower threaded rod-helical tube boss 405h and does not non-rotatably engage with the helical tube-threaded rod positioning slot 506e of the helical tube 5, the helical tube 5 and the lifting mechanism 82 can be non-rotatably connected.

[0104] A stick-type cosmetic dispensing container according to Example 3 of the present invention will be described with reference to Figures 12 and 13. The stick-type cosmetic dispensing container according to Example 3 of the present invention is a variation of the stick-type cosmetic dispensing container according to Example 1 of the present invention. The stick-type cosmetic dispensing containers according to Examples 1 and 3 of the present invention differ in the method of attaching the stick-type cosmetic 1. As described above, the method of attaching the stick-type cosmetic 1 to the stick-type cosmetic dispensing container according to Example 1 of the present invention is the "in-container cosmetic filling and molding method." On the other hand, the stick-type cosmetic dispensing container according to Example 3 of the present invention is the "external cosmetic molding and attachment method," in which a stick-type cosmetic preformed outside the container is attached to the container using a mold (not shown), as shown in Figure 13. The only difference in the configuration of the stick-type cosmetic dispensing container according to Example 1 of the present invention and the stick-type cosmetic dispensing container according to Example 3 of the present invention is the cosmetic holding portion 201 of the holding tube 2.

[0105] The configuration of the cosmetic holding portion 201 of the holding barrel 2 according to the third embodiment of the present invention will be described in detail below with reference to Figures 12 and 13. As shown in Figure 13, the cosmetic holding portion 201 of the holding barrel 2 has plate-shaped cosmetic holding ribs 201c extending from the inner surface to the inner bottom surface. Three or more cosmetic holding ribs 201c may be evenly spaced on the inner surface of the cosmetic holding portion 201; in this embodiment, eight cosmetic holding ribs 201c are evenly spaced on the inner surface. Air escape holes 201d are drilled through the bottom wall on the inner bottom surface of the cosmetic holding portion 201.

[0106] Next, we will explain the stick-type cosmetic 1 formed by the "cosmetic ex-container molding and mounting method." The outer diameter of the application portion 101 of the stick-type cosmetic 1 is slightly smaller than the inner diameter of the sleeve-to-cosmetic sliding surface 301 of the sleeve 3. The outer diameter of the held portion 102 below this application portion 101 is slightly smaller than the inner diameter of the cosmetic holding portion 201 of the holding tube 2. A stepped cosmetic-to-holding tube abutment portion 103 is provided between this held portion 102 and the application portion 101. Because this stick-type cosmetic 1 is formed in advance outside the container using a mold, it is possible to apply engraving or the like to the portion of the mold corresponding to the upper end surface of the application portion 101 of the stick-type cosmetic 1, and it is also possible to create a design-oriented shape for the tip surface 104 of the application portion 101 of the stick-type cosmetic 1.

[0107] A method for attaching the stick-type cosmetic material 1 to the stick-type cosmetic material dispensing container of Example 3 of the present invention using the "external molding and attachment method for cosmetics" will be described with reference to Figure 13. In the container body 81 of the stick-type cosmetic material dispensing container of Example 3 of the present invention, the holding tube 2 is first raised to the position where the upper limit position limiting mechanism 83 is activated. The held portion 102 of the stick-type cosmetic material 1, which has been molded using a mold, is inserted from the upper end of the sleeve 3 and fitted into the cosmetic material holding portion 201 of the holding tube 2. At this time, the cosmetic material holding rib 201c in the cosmetic material holding portion 201 has an inscribed circle diameter smaller than the outer diameter of the held portion 102 of the stick-type cosmetic material 1, causing interference; however, because the cosmetic material holding rib 201c is arranged parallel to the axis (insertion direction), the stick-type cosmetic material 1 can be fitted with the cosmetic material holding rib 201c wedged into the held portion 102. The cosmetic-retaining ribs 201c of the holding tube 2 bite into the held portion 102 of the stick-shaped cosmetic 1, thereby improving the holding force of the holding tube 2 on the stick-shaped cosmetic 1. When the stick-shaped cosmetic 1 is inserted, the air that had filled the cosmetic-retaining portion 201 is gradually discharged through the air escape holes 201d on the bottom surface as the held portion 102 is inserted. The stick-shaped cosmetic 1 is inserted until the cosmetic-retaining tube abutment portion 103 abuts against the tip of the holding tube 2.

[0108] After the stick-type cosmetic material 1 is attached, as shown in Figure 12, the holding tube 2 is lowered to the operating position of the lower limit position limiting mechanism 84, and the application part 101 of the stick-type cosmetic material 1 is housed in the sleeve-cosmetic material sliding surface 301 of the sleeve 3. At this time, the tip surface 104 of the stick-type cosmetic material 1, which has been given a decorative design, is exposed from the tip of the sleeve 3 and can be seen.

[0109] Next, among the effects of the stick-type cosmetic material dispensing container of Example 3 of the present invention, those that differ from those of Example 1 of the present invention will be described. Example 3 of the present invention can accommodate a method of attaching a stick-type cosmetic material by the "external cosmetic material container molding and attachment method," which Example 1 of the present invention was unable to accommodate. Furthermore, the stick-type cosmetic material 1 formed by this "external cosmetic material container molding and attachment method" can have a decorative shape on the tip surface 104 of the application part 101, improving the design of the stick-type cosmetic material 1. Furthermore, the shape of the tip surface 104 of the application part 101 makes it easy to determine whether the stick-type cosmetic material 1 has been used or is unused.

[0110] In the stick-type cosmetic material dispensing containers of Examples 1 and 3 of the present invention, the means for forming the stick-type cosmetic material 1 have been described as "a method for filling and molding cosmetics into a container" in Example 1 of the present invention and "a method for molding and attaching cosmetics to an external container" in Example 3 of the present invention. However, both of the means for forming the stick-type cosmetic material 1 are consistent in that the cosmetic material is made fluid, filled into a dispensing container or a mold, and then solidified. In Examples 1 and 3 of the present invention, the cosmetic material is melted by heating to make it fluid, and then solidified by cooling. In addition to this method, a method is also possible in which the cosmetic material is dissolved in a volatile solvent to make it fluid, and then the volatile components are evaporated to solidify it.

[0111] A stick-type cosmetic material dispensing container according to Example 4 of the present invention will be described with reference to Figures 14 to 17. The stick-type cosmetic material dispensing container according to Example 4 of the present invention is one variation of the stick-type cosmetic material dispensing container according to Example 1 of the present invention. The stick-type cosmetic material dispensing container according to Example 1 and Example 4 of the present invention differ in the method of removing the lifting mechanism 82.

[0112] Specifically, as shown in Fig. 5, the stick type cosmetic material dispensing container of Example 1 of the present invention holds (fixes) the sheath tube 5 of the container body 81 and presses the sleeve 3 of the lifting mechanism 82 downward, and the downward force of the sleeve 3 disengages the sheath tube 5 from the threaded rod 4 of the lifting mechanism 82, and the lifting mechanism 82 is removed from the mechanism insertion hole 503 of the sheath tube 5. In contrast, as shown in Fig. 16, the stick type cosmetic material dispensing container of Example 4 of the present invention uses the drive male screw 401 of the threaded rod 4 of the lifting mechanism 82 to lower the lifting mechanism 82 downward, and the downward force of the lifting mechanism 82 disengages the sheath tube 5 from the threaded rod 4 of the lifting mechanism 82, and the lifting mechanism 82 is removed from the mechanism insertion hole 503 of the sheath tube 5.

[0113] Comparing the configuration of the stick type cosmetic material dispensing container of Example 1 of the present invention with the configuration of the stick type cosmetic material dispensing container of Example 4 of the present invention, the configuration of the drive male screw 401 of the threaded rod 4 is different. Details of the drive male screw 401 of the stick type cosmetic material dispensing container of Example 4 of the present invention will be described below. The drive male screw 401 of the threaded rod 4 is provided longer than the vertical sliding length of the holding tube 2, which is limited by the upper limit position limiting mechanism 83 and the lower limit position limiting mechanism 84. The extended portion of this drive male screw 401 is located above the upper limit position limiting mechanism 83. In Example 4 of the present invention, as shown in Figure 17, the drive male screw 401 is provided up to the upper end of the threaded rod 4. Alternatively, the length of the threaded rod 4 is increased so that the upper end of the drive male screw 401 extends above the upper limit position limiting mechanism 83. As a result, the second upper limit position limiting mechanism 8302 of the driving male screw 401 described in the first embodiment of the present invention does not exist, and the upper limit position limiting mechanism 83 of the fourth embodiment of the present invention consists solely of the first upper limit position limiting mechanism 8301 (see FIG. 15). The lower limit position limiting mechanism 84 is made up of the retaining tube-threaded rod abutment portion 206 at the lower end of the retaining tube 2 and the threaded rod-retaining tube abutment portion 402 of the threaded rod 4.

[0114] Next, the procedure for removing (disassembling) the lifting mechanism 82 of the stick-type cosmetic material dispensing container of Example 4 of the present invention will be described with reference to Figure 16. The container body 81 is raised, and the retaining tube-sleeve abutment portion 203 of the retaining tube 2 is brought into contact with the sleeve inner wall step portion 303 of the sleeve 3, and is locked at the upper limit position by the first upper limit position limiting mechanism 8301 of the upper limit position limiting mechanism 83. When the retaining tube 2 is raised further from this upper limit locked state, the male drive screw 401 of the threaded rod 4 is threaded above the locking position of the retaining tube 2 by the upper limit position limiting mechanism 83, and the retaining tube 2 is restricted from rising by the upper limit position limiting mechanism 83, so that the threaded rod 4 is lowered relatively by the screwing action. This downward stress that moves the threaded rod 4 down acts on the threaded rod-Hawk tube engagement boss 405a of the threaded rod 4 engaged with the Hawk tube-threaded rod engagement portion 506c of the Hawk tube 5, causing the threaded rod-Hawk tube engagement boss 405a to descend relatively from the Hawk tube-threaded rod engagement portion 506c. Due to this downward stress, the lower slope 405c of the threaded rod-Hawk tube engagement boss 405a pushes apart the Hawk tube-threaded rod engagement portion 506c by a wedge action and slips inside the Hawk tube-threaded rod joint portion 506, causing the engagement between the threaded rod-Hawk tube engagement boss 405a and the Hawk tube-threaded rod engagement portion 506c to be released. However, the engagement between the threaded rod-Hawk tube anti-rotation boss 405e and the Hawk tube-threaded rod anti-rotation slot 506a, that is, the engagement that prevents the threaded rod 4 from rotating relative to the Hawk tube 5, is maintained, and the screwing action caused by the relative rotation of the threaded rod 4 and the holding tube 2 continues, and the threaded rod 4 is advanced downward. As a result, the threaded rod-Hawk tube coupling portion 405 protrudes from the mechanism insertion hole 503 of the Hawk tube 5. The lifting mechanism 82 can be removed by pinching this protruding threaded rod-Hawk tube coupling portion 405.

[0115] The method for removing the lifting mechanism 82 of Example 4 of the present invention has been described above. With the stick-type cosmetic material dispensing container of Example 4 of the present invention, the lifting mechanism 82 can also be removed by the method for removing the lifting mechanism 82 of Example 1 of the present invention shown in Figure 5, that is, by pushing down the sleeve 3 and pushing the threaded rod-to-shank barrel joint 405 out of the mechanism insertion hole 503 of the shako barrel 5. In this case, the lifting mechanism 82 can be removed regardless of the stopping position of the holding barrel 2 within the lifting mechanism 82, but there is an increased risk of the lifting mechanism 82 being accidentally detached.

[0116] The action and effect of the stick-type cosmetic material dispensing container of Example 4 of the present invention will be described. In the stick-type cosmetic material dispensing container of Example 4 of the present invention, not only can the lifting mechanism 82 be removed by rotating the hakama tube 5, but the method of removing the lifting mechanism 82 described in Example 1 of the present invention is also possible. In the method of removing the lifting mechanism 82 of Example 4 of the present invention, the position of the holding tube 2 is limited to an upper limit, but because the screw multiplying effect can be used to release the engagement between the hakama tube 5 and the lifting mechanism 82, the removal operation can be performed easily even if the engagement between the hakama tube 5 and the lifting mechanism 82 is made strong to prevent unintentional disengagement.

[0117] The above has described the stick-type cosmetic material dispensing container of Example 1 of the present invention, and the stick-type cosmetic material dispensing containers of Examples 2 to 4 of the present invention, which are variations of the stick-type cosmetic material dispensing container of Example 1 of the present invention. The stick-type cosmetic material dispensing containers of Examples 2 to 4 of the present invention can be implemented not only independently of Example 1 of the present invention, but also in combination with Examples 2 to 4 of the present invention. Combinations of Examples 2 to 4 of the present invention that can be implemented with the stick-type cosmetic material dispensing container of Example 1 of the present invention are the combination of Examples 2 and 3, the combination of Examples 2 and 4, and the combination of Examples 2, 3, and 4.

[0118] A stick-type cosmetic dispensing container according to Example 5 of the present invention will be described with reference to Figures 18 to 20. The stick-type cosmetic dispensing container according to Example 1 of the present invention described above, and the stick-type cosmetic dispensing containers according to Examples 2 to 4 of the present invention, which are variations of the stick-type cosmetic dispensing container according to Example 1 of the present invention, can be separated into the components that make up the container, sorted by material, and discarded or recycled. In contrast, the stick-type cosmetic dispensing container according to Example 5 of the present invention is different in that it is a cartridge-type stick-type cosmetic dispensing container in which the lifting mechanism 82 is made into a cartridge, and the used lifting mechanism 82 is replaced with a new lifting mechanism 82, and the exterior member 86 is reused.

[0119] The configuration of the cartridge-type stick-type cosmetic dispensing container of Example 5 of the present invention will be described below with reference to Figures 18 and 19. Among the components of the stick-type cosmetic dispensing container of Example 5 of the present invention, the same components and parts as those of the stick-type cosmetic dispensing container of Example 1 of the present invention are designated by the same reference numerals. Furthermore, among the components of the stick-type cosmetic dispensing container of Example 5 of the present invention, the configurations of the stick-type cosmetic 1, holding tube 2, hakama tube 5, sliding resistor 6, and cap 7 are completely identical to those of the stick-type cosmetic dispensing container of Example 1 of the present invention, and therefore a description of the stick-type cosmetic dispensing container of Example 5 of the present invention will be omitted. The remaining elements, the threaded rod 4 and sleeve 3, are partially different in configuration from the threaded rod 4 and sleeve 3 of the stick-type cosmetic dispensing container of Example 1 of the present invention. Details of these components will be described below.

[0120] The threaded rod 4 of Example 5 of the present invention differs from the threaded rod 4 of Example 1 of the present invention in the configuration of the threaded rod-sleeve sliding contact portion 403. In addition to the O-ring groove 403a, a threaded rod-sleeve shaft mounting groove 403b is engraved on the outer peripheral wall of the threaded rod-sleeve sliding contact portion 403. Note that, although the threaded rod-sleeve shaft mounting groove 403b is provided above the O-ring groove 403a in Figures 18 and 19, the vertical positional relationship between the O-ring groove 403a and the threaded rod-sleeve shaft mounting groove 403b can also be reversed.

[0121] The sleeve 3 of Example 5 of the present invention differs from the sleeve 3 of Example 1 of the present invention in the configuration of the sleeve-threaded rod sliding surface 305. A sleeve-threaded rod shaft-mounting protrusion 305a is circumferentially protruded from the sleeve-threaded rod sliding surface 305 of the sleeve 3 at a position facing the threaded rod-sleeve shaft-mounting groove 403b. The inner diameter of this sleeve-threaded rod shaft-mounting protrusion 305a is smaller than the outer diameter of the threaded rod-sleeve sliding portion 403 and larger than the outer diameter of the bottom surface of the threaded rod-sleeve shaft-mounting groove 403b. This sleeve-threaded rod shaft-mounting protrusion 305a rotatably and non-detachably engages with the threaded rod-sleeve shaft-mounting groove 403b. This engagement between the threaded rod-sleeve shaft-mounting groove 403b and the sleeve-threaded rod shaft-mounting protrusion 305a makes the lifting mechanism 82, which is made up of the retaining tube 2, the threaded rod 4, the sleeve 3, and the sliding resistor 6, non-disassembly possible.

[0122] Next, a method for assembling the stick-type cosmetic material dispensing container of Example 5 of the present invention will be described. This description is based on the process assumed by a manufacturer of the stick-type cosmetic material dispensing container of Example 5 of the present invention. Below, a method for assembling the lifting mechanism 82 of Example 5 of the present invention, which differs from Example 1 of the present invention, will be described.

[0123] Before assembly, the sleeve 3 does not have the sleeve-threaded rod axial mounting protrusion 305a on the sleeve-threaded rod sliding surface 305. In this state, a composite consisting of the retaining tube 2, the threaded rod 4, and the sliding resistor 6 is inserted from the lower end of the sleeve 3 until the threaded rod-sleeve abutment portion 404 of the threaded rod 4 abuts against the sleeve-threaded rod abutment portion 306 of the sleeve 3. This composite can be inserted without any obstruction because there is nothing interfering with the inner surface of the sleeve 3. After the retaining tube 2, the threaded rod 4, and the sliding resistor 6 are combined with the sleeve 3, bead machining is performed from the outer periphery of the sleeve 3 toward the threaded rod-sleeve abutment groove 403b of the threaded rod 4, forming a sleeve-threaded rod axial mounting protrusion 305a on the sleeve-threaded rod sliding surface 305 of the sleeve 3 that rotatably and non-detachably engages with the threaded rod-sleeve abutment groove 403b. By engaging the sleeve-threaded rod shaft mounting protrusion 305a with the threaded rod-sleeve shaft mounting groove 403b, the retaining tube 2, the threaded rod 4 and the sliding resistor 6 are inseparably combined within the sleeve 3, thereby forming the lifting mechanism 82.

[0124] In the stick-type cosmetic material dispensing container of Example 5 of the present invention, the sleeve-threaded rod shaft-mounting projections 305a are continuously formed by bead processing on the inner peripheral wall of the sleeve-threaded rod sliding surface 305. The sleeve-threaded rod shaft-mounting projections 305a can be formed by any method that can be freely selected as long as it can be formed from the outer periphery of the sleeve 3 to the sleeve-threaded rod sliding surface 305 after the retaining tube 2, the threaded rod 4, and the sliding resistor 6 are combined with the sleeve 3. For example, pin crimping may be performed from the outer periphery of the sleeve 3 inward, so that the sleeve-threaded rod shaft-mounting projections 305a that engage with the threaded rod-sleeve shaft-mounting grooves 403b are intermittently protruded and formed on the sleeve-threaded rod sliding surface 305.

[0125] The upper part of the lifting mechanism 82 and the upper end of the sleeve 3 are inserted through mechanism insertion hole 503 at the lower end of the sheath tube 5, and the sheath tube-threaded rod anti-rotation slot 506a and the sheath tube-threaded rod engagement hole 506b of the sheath tube 5 are engaged with the threaded rod-threaded rod anti-rotation boss 405e and the threaded rod-threaded rod engagement boss 405a of the threaded rod-threaded rod coupling portion 405 of the threaded rod 4, thereby combining the sheath tube 5 and the lifting mechanism 82 non-rotatably but detachably. At this time, because the sleeve 3 of the lifting mechanism 82 is rotatably and non-detachably engaged with the threaded rod 4 of the lifting mechanism 82, there is no need for a mechanism to prevent the sleeve 3 from coming off upward, as is the case with the sheath tube-sleeve abutment portion 504 of the stick-type cosmetic feeding container of Example 1 of the present invention.

[0126] A method of using the stick-type cosmetic material dispensing container of Example 5 of the present invention will be described. This description is based on the assumption that the container will be operated by a consumer who has purchased the stick-type cosmetic material dispensing container of Example 5 of the present invention. Note that the operation of raising and lowering the stick-type cosmetic material 1 in Example 5 of the present invention is the same as the operation of raising and lowering the stick-type cosmetic material 1 in Example 1 of the present invention described above, and therefore a description thereof will be omitted. Here, the procedure for disposing of and reusing a used stick-type cosmetic material dispensing container, which differs from Example 1 of the present invention, will be described with reference to Figures 19 and 20.

[0127] When the sleeve 3 of the lifting mechanism 82 is pressed downward while holding (fixing) the spool tube 5 of the container body 81 after the stick-type cosmetic material 1 has been used, the threaded rod-spool tube engagement boss 405a of the threaded rod 4 disengages from the spool tube-spool tube engagement hole 506b of the spool tube 5, and the lifting mechanism 82 can be removed from the spool tube 5 (see FIG. 19). This lifting mechanism 82 cannot be disassembled and disposed of separately because the sleeve-spool tube mounting projection 305a of the sleeve 3 is non-detachably engaged with the threaded rod-sleeve mounting groove 403b of the threaded rod 4. Therefore, the lifting mechanism 82 can be discarded as is, and a new lifting mechanism 82 containing a new stick-type cosmetic material 1 is attached to the spool tube 5, thereby reusing the exterior member 86, which is decorated with attractive, expensive ornaments (see FIG. 20).

[0128] The following describes the operation and effects of the stick-type cosmetic material dispensing container of Example 5 of the present invention, which do not overlap with those of the stick-type cosmetic material dispensing containers of Examples 1 to 4 of the present invention. In the stick-type cosmetic material dispensing container of Example 5 of the present invention, the sleeve-threaded rod shaft mounting protrusion 305a of the lifting mechanism 82 is non-detachably engaged with the threaded rod-sleeve shaft mounting groove 403b, so the lifting mechanism 82 cannot be disassembled. Therefore, by making the lifting mechanism 82 detachable from the hakama tube 5, the old lifting mechanism 82 can be discarded and replaced with a lifting mechanism 82 containing a new stick-type cosmetic material 1, thereby creating a cartridge-type stick-type cosmetic material dispensing container in which the lifting mechanism 82 serves as a cartridge. This allows the exterior member 86, which is decorated with attractive and expensive ornaments, to be reused, thereby reducing waste.

[0129] The stick-type cosmetic material dispensing container of Example 5 of the present invention has been described above. As already explained, Examples 2 to 4 of the present invention are variations of the stick-type cosmetic material dispensing container of Example 1 of the present invention and can be implemented in combination with Example 1 of the present invention. However, the stick-type cosmetic material dispensing container of Example 5 of the present invention can also be implemented in combination with Examples 2 and 3 of the present invention. Specifically, combinations of Examples 5 and 2 of the present invention, Examples 5 and 3 of the present invention, and Examples 5, 2 and 3 of the present invention can be implemented. Note that Example 4 of the present invention requires relative vertical sliding between the sleeve 3 and the threaded rod 4, which contradicts Example 5 of the present invention in which the sleeve 3 and the threaded rod 4 are combined so as not to slide, and therefore cannot be implemented in combination.
