Description

Technical Field

[0001] The present invention relates to a rod-shaped cosmetic dispensing container for accommodating rod-shaped cosmetics such as lipsticks and stick foundations, and dispensing and using such rod-shaped cosmetics. More specifically, the rod-shaped cosmetics are cartridgeized so that the used-up rod-shaped cosmetics can be replaced, enabling the reuse of the container itself, reducing waste, and separately disposing of the discarded cartridges into metal members and synthetic resin members, which relates to an environmentally considerate cartridge-type rod-shaped cosmetic dispensing container.

Background Art

[0002] Conventionally, a rod-shaped cosmetic dispensing container for accommodating rod-shaped cosmetics such as lipsticks and stick foundations and dispensing and applying such rod-shaped cosmetics is divided into a structural part having a rod-shaped cosmetic and a dispensing mechanism, and an exterior body with a nice-looking decoration, and the structural part and the exterior body are detachably connected to make the structural part into a replaceable cartridge. Such a cartridge-type rod-shaped cosmetic dispensing container is known. When the rod-shaped cosmetic is used up, only the empty structural part is discarded, and the expensive exterior body with a nice-looking decoration is reused. Therefore, this cartridge-type rod-shaped cosmetic dispensing container can reduce waste and can be said to be an environmentally considerate container.

[0003] In addition, the container is composed of a combination of a metal material and a synthetic resin material. There are various materials with different characteristics for both the metal material and the synthetic resin material. For the members of the container, materials suitable for the required characteristics are selected, combined, and arranged in appropriate places. The metal material is highly strong and can be decorated with a unique texture, luster, and various decorations of the metal, so it is widely used for exterior members. The synthetic resin material can be molded into complex shapes and has good characteristics such as slidability, chemical resistance, and corrosion resistance, so it is widely used for mechanism members that are not exposed to the outside. Currently, a recycling route has been established for each metal material, and each material can be recycled by separation. The synthetic resin material can only recycle limited synthetic resin materials, and the rest have to be discarded as garbage.

[0004] In this cartridge-type retractable cosmetic container, the cartridge consists of a retractable cosmetic and a structural part having a retractable mechanism. Of the structural part, the retractable mechanism component is molded from synthetic resin, and the part exposed to the outside is covered with a thin metal sleeve. If this cartridge is discarded as is, it will simply become waste, so a configuration is needed that allows the metal sleeve to be removed, the container to be disassembled into metal material and synthetic resin material, and the metal material to be separated and recycled. Configurations that allow the metal sleeve to be disassembled from this container and disposed of separately are known, as described in Patent Documents 1 and 2.

[0005] In the lipstick storage container described in Patent Document 1, a retaining mechanism protruding from the inner circumferential wall of a metal outer cylinder engages with a circumferential groove provided on the side outer wall of a synthetic resin inner cylinder, thereby rotatably connecting the outer and inner cylinders. The inner cylinder has a cut groove that crosses the circumferential groove vertically in the axial direction, allowing the circumferential groove to deform and release the engagement of the retaining mechanism on the outer cylinder. In the normal use state, the shaft hanging down from the dish member is positioned behind the inner cylinder, preventing deformation of the circumferential groove and making it impossible to remove the outer cylinder. However, when the dish member is raised to its upper limit, the shaft of the inner cylinder is no longer held in place, allowing the circumferential groove of the inner cylinder to deform, and the outer cylinder can be forcibly removed.

[0006] Furthermore, in the cosmetic storage container described in Patent Document 2, a locking piece protruding from the inner circumferential wall of a metal outer cylinder member engages with an engagement groove provided on the side outer wall of a synthetic resin inner cylinder member, thereby rotatably connecting the outer cylinder member and the inner cylinder member. The inner cylinder member has a groove that crosses the engagement groove vertically in the axial direction so that the engagement groove can be deformed and the locking piece of the outer cylinder member can be released. In the normal use state of this container, a deflection prevention piece of the insertion member prevents deformation of the engagement groove of the inner cylinder member, making it impossible to remove the outer cylinder member. However, when the structural part (cartridge) consisting of the dish member, inner cylinder member, and outer cylinder member is removed from the outer casing (consisting of the skirt member and insertion member), the restraint of the deflection prevention piece of the insertion member is removed, the engagement groove of the inner cylinder member becomes deformable, and the outer cylinder member can be forcibly removed.

[0007] Furthermore, the containers described in Patent Documents 2 and 3 are equipped with a rotational resistance-providing mechanism that generates appropriate rotational friction resistance during rotational dispensing operations to provide a good operating feel. The rotational resistance-providing mechanism described in Patent Document 2 has an elastic projection on the inner cylinder member, and this projection is elastically brought into contact with the inner wall of the outer cylinder member, and this elasticity generates sliding friction resistance when the inner cylinder member and the outer cylinder member rotate relative to each other. The rotational resistance-providing mechanism described in Patent Document 3 has an O-ring made of an elastic material fitted into the helical cylinder, and this O-ring is elastically brought into contact with the inner wall of the sleeve, and this elasticity generates sliding friction resistance when the helical cylinder and the sleeve rotate relative to each other. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 11-127952 [Patent Document 2] Japanese Patent Publication No. 2000-300334 [Patent Document 3] Japanese Patent Publication No. 11-164732 [Overview of the project] [Problems that the invention aims to solve]

[0009] Patent Document 1 describes a configuration in which the outer cylinder member is directly removed from the container, and is only applicable to containers where only the outer cylinder member is made of a different material. In other words, it is not possible to apply highly decorative designs using different materials such as metal to the container exterior. In contrast, Patent Document 2 divides the container into an up-and-down movement mechanism consisting of an inner cylinder member, a dish member, and an outer cylinder member, and an exterior body consisting of a skirt member, an insertion member, and a cap, with the engagement groove of the inner cylinder member and the fitting and fixing means of the insertion member being removably engaged, resulting in a cartridge-type container. In other words, the exterior body is reused, and the outer cylinder member, which is made of a different material, can be removed and disposed of separately from the up-and-down movement mechanism that is to be discarded. In Patent Document 2, with the deflection prevention piece of the insertion member engaged with the groove of the inner cylinder member, the engagement groove of the inner cylinder member and the fitting and fixing means of the insertion member are removably engaged, preventing inward deflection of the inner cylinder member when the up-and-down movement mechanism is removed, preventing the engagement of the locking groove and locking piece from being released, and preventing the outer cylinder member from falling out. However, when connecting the vertical movement mechanism and the outer casing by engaging the engagement groove of the inner cylinder member of the vertical movement mechanism with the fitting and fixing means of the insertion member of the outer casing, it is necessary to engage the cut groove of the inner cylinder member with the deflection prevention piece of the insertion member, and thus a predetermined positional alignment in the circumferential direction is required between the inner cylinder member and the insertion member.

[0010] In Patent Document 1, the outer cylinder member is crimped or punched from the outside inward, in accordance with a circumferential groove provided in the inner cylinder member, thereby connecting the outer cylinder member so that it can rotate freely. In Patent Document 2, a locking piece projecting from the inner wall of the outer cylinder member is engaged with a locking groove provided in the inner cylinder member, thereby connecting the inner cylinder member and the outer cylinder member so that they can rotate freely. In Patent Document 3, an engaging rib projecting from the inner wall of the sleeve is engaged with an engaging recess provided in the spiral cylinder, thereby connecting the sleeve and the spiral cylinder so that they can rotate freely. The crimping and punching in Patent Document 1, the locking piece in Patent Document 2, and the engaging rib in Patent Document 3 all protrude from the inner wall of the outer cylinder member in Patent Documents 1 and 2, and the sleeve in Patent Document 3. Furthermore, the outer walls of the dish members of Patent Documents 1 and 2, and the retaining cylinder of Patent Document 3 are provided with protruding engaging pins of Patent Document 1, engaging pieces of Patent Document 2, and longitudinal ribs of Patent Document 3, which engage with the engaging grooves of Patent Documents 1 and 2 and the guide grooves of Patent Document 3 on the outer cylinder members of Patent Documents 1 and 2 and the inner wall of the sleeve of Patent Document 3. In addition, the outer wall of the inner cylinder member of Patent Document 2 is provided with a protruding rotational resistance-applying portion, and the outer wall of the helical cylinder of Patent Document 3 is fitted with a protruding O-ring, which elastically contacts the inner wall of the outer cylinder member of Patent Document 2 and the sleeve of Patent Document 3, thereby constituting a rotational resistance-applying mechanism.

[0011] In other words, after processing and forming the outer cylinder member of Patent Documents 1 and 2 and the sleeve of Patent Document 3 with the crimping or punching process of Patent Document 1, the locking piece of Patent Document 2, and the engaging rib of Patent Document 3, the crimping or punching process of Patent Document 1, the locking piece of Patent Document 2, and the engaging rib of Patent Document 3 interfere with the engaging pin of Patent Document 1, the engaging piece of Patent Document 2, and the longitudinal rib of Patent Document 3 of the dish member of Patent Documents 1 and 2 and the holding cylinder of Patent Document 3, making assembly impossible. In addition, if a rotational resistance mechanism is provided as in Patent Documents 2 and 3, the locking piece of Patent Document 2 and the engaging rib of Patent Document 3 also interfere with the rotational resistance mechanism, specifically the rotational resistance component of Patent Document 2 and the O-ring of Patent Document 3.

[0012] Therefore, in Patent Document 1, after assembling the outer cylinder member to the inner cylinder member and the dish member, crimping or punching is performed in accordance with the circumferential groove of the inner cylinder member to rotatably connect the outer cylinder member and the inner cylinder member and avoid interference during assembly. In this post-assembly processing, a roll tooth or punch is pressed against the outer wall of the outer cylinder member in accordance with the circumferential groove of the inner cylinder member to form the inner wall. The receiving mold for this roll tooth or punch is the circumferential groove of the inner cylinder member, and moreover, a cut groove crosses this circumferential groove, making it very weak in terms of strength. Consequently, the protrusions on the inner wall of the inner cylinder member formed by processing with the roll tooth or punch have a large protrusion and cannot be made sharp in shape. In addition, the crimping or punching of the outer cylinder member interferes with the engagement pin or rotational resistance mechanism of the dish member, so it is necessary to forcibly remove the outer cylinder member in order to disassemble it. Therefore, there are limitations to the amount of protrusion caused by crimping or punching of the outer cylinder member, and there are limits to how strong the engagement strength between the circumferential groove of the inner cylinder member and the crimping or punching of the outer cylinder member can be, which poses a risk of the outer cylinder member accidentally falling off during cartridge attachment or detachment.

[0013] In view of the above points, the present invention aims to provide an environmentally friendly cartridge-type retractable cosmetic container in which the red cylinder, rotating cylinder, and sleeve can be assembled without interference, the cartridge can be attached and detached and the retractable position of the retractable cosmetic can be operated without hindrance, and the sleeve can be easily disassembled and separated for disposal.
