Description

[Technical Field]

[0001] The present invention relates to a stick-shaped cosmetic container capable of compactly storing stick-shaped cosmetics such as lipstick, lip balm, and stick foundation. [Background technology]

[0002] Patent Document 1 proposes a storage container for this type of stick-shaped cosmetic material, in which a holding tube (9) containing stick-shaped cosmetics is housed in a container body (8). This storage container is configured as a container for housing a plurality of stick-shaped articles (A), and elastic locking pieces (11) are provided by cutting out the side of the holding tube (9) that houses each stick-shaped article (A). A spring (13) disposed at the bottom of the holding tube (9) is compressed by the holding tube (9), and the long edge (6a) at the upper end of the elastic locking piece (11) is locked from the inside to the upper part of a window hole (6) formed in the side wall (5) of the container body (8).

[0003] In this state, when the elastic locking piece (11) is released from the outside of the window hole (6), the elastic force of the spring (13) presses the holding tube (9) toward the insertion port (4), causing the rod-shaped article (A) to protrude. The holding tubes (9) are arranged in parallel inside the container body (8), and multiple rod-shaped articles (A) are stored in each holding tube (9) and can be individually removed.

[0004] Meanwhile, a storage cylinder for storing tools necessary for makeup is described in Patent Document 2. This storage cylinder has a structure in which a tongue-shaped locking mechanism (8) is provided along the longitudinal direction from the longitudinal end of a fitting cylinder (4) that stores the makeup tools (11).

[0005] This locking mechanism (8) has a tongue-shaped configuration in which an operating pin (7) protrudes from the outside of the longitudinal end of the locking mechanism (8), and this operating pin (7) is slidably arranged in a slit groove (3) formed on the side of the storage tube main body (1), and an operating pin root (10) formed around the operating pin (7) is locked in a locking groove (9) formed at the upper end of the slit groove (3). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 59-193179 [Patent Document 2] Japanese Patent Publication No. 2022-161055 Summary of the Invention [Problem to be solved by the invention]

[0007] The rod-shaped article storage container of Patent Document 1 has an elastic locking piece (11) cut out from the side of the holding tube (9), which causes the holding tube (9) to deform radially and is therefore not suitable for storing a rod-shaped article (A). Moreover, since the container is designed to store multiple rod-shaped articles (A), it is not capable of compactly storing a single rod-shaped article (A).

[0008] On the other hand, the storage tube of Patent Document 2 has a tongue-shaped locking mechanism (8) extending longitudinally from the longitudinal end of the fitting tube (4), so that the overall length of the storage tube body (1) that houses the fitting tube (4) and the locking mechanism (8) is long.

[0009] Moreover, this locking mechanism (8) is configured so that the operating pin (7) protruding outward from the longitudinal end of the cylindrical storage body (1) is operated along the slit groove (3) formed on the side of the cylindrical storage body (1), and therefore the operating position of the operating pin (7) is on the longitudinal end side of the cylindrical storage body (1), opposite the side from which the cosmetic tool (11) is inserted. If the operating pin (7) is in such a position, operability will be poor.

[0010] In stick-shaped cosmetic containers, the cosmetics themselves are stick-shaped, such as lipstick, so it is desirable that the overall length of the container be as compact as possible. Moreover, even in a compact container, it is even more desirable that the operation of taking out the cosmetics be as easy as possible.

[0011] The present invention has been created to solve the above-mentioned problems, and has as its object to provide a stick-type cosmetic container that can store stick-type cosmetics compactly and is easy to operate. [Means for solving the problem]

[0012] The first means of the present invention for achieving the above object comprises a feeding mechanism 10 that moves a stick-shaped cosmetic material up and down by the relative rotation of a sleeve 12 and a hakama tube 11; an outer tube 20 that stores the stick-shaped cosmetic material P stored in the sleeve 12 together with the feeding mechanism 10; an inner tube 30 that is slidably stored within the outer tube 20 and has a storage recess 31 into which the sleeve 12 is fitted from the tip side and stored; and a spring 40 that is installed on the bottom side of the outer tube 20 and presses and urges the bottom side of the inner tube 30. An elastic tongue piece 32 is formed on a part of the side surface of the inner cylinder 30, and a locking projection 33 is provided on the outside of the elastic tongue piece 32. In the stick-shaped cosmetic container, The elastic tongue piece 32 is formed in a band shape along the circumferential direction by horizontally cutting out a part of the side surface of the inner tube 30, and the locking projection 33 is provided on the outer side of the tip of the elastic tongue piece 32, A storage locking window 21 into which a locking projection 33 locks from the inside when the stick-type cosmetic material P is stored, and a protruding locking window 22 through which the locking projection 33 protrudes from the inside when the stick-type cosmetic material P is used are opened at the longitudinal center of a side surface of the outer tube 20, At least the lower end of the storage locking window 21 is provided near the lower longitudinal center of the side surface of the outer tube 20, and at least the upper end of the protruding locking window 22 is provided near the upper longitudinal center of the side surface of the outer tube 20, and protruding operation portions for pushing in the locking protrusions 33 are provided near the upper and lower longitudinal centers of the side surface of the outer tube 20. The reason is that.

[0013] Second Option The cross-sectional shape of the outer tube 20 is similar to the cross-sectional shape of the hakama tube 11, and has a flat portion on at least a part of the side surface, so that the hakama tube 11 is stored in the outer tube 20 so that it cannot rotate, and the storage locking window 21 and the protruding locking window 22 are formed in the flat portion.

[0014] Third Option The outer cylinder 20 has a rectangular cross section and is formed with the storage locking window 21 and the protrusion locking window 22 in the longitudinal center portion.

[0015] In the fourth means, the protruding operation portion is the locking protrusion 33. .

[0016] The fifth means comprises a push button 50 that is slidably engaged with the outer cylinder 20 and pushes the locking projection 33, and the protruding operation portion is the push button 50. . [Effects of the Invention]

[0017] According to the present invention, an elastic tongue piece 32 is formed on a part of the side surface of the inner tube 30, and a locking protrusion 33 is provided on the outside of the elastic tongue piece 32. The storage locking window 21 into which the locking protrusion 33 locks when the stick-shaped cosmetic material P is stored, and the protruding locking window 22 from which the locking protrusion 33 protrudes when the stick-shaped cosmetic material P is used are opened at the longitudinal center of the side surface of the outer tube 20, thereby enabling the stick-shaped cosmetic material to be stored compactly.

[0018] Furthermore, the locking projection 33 is provided on an elastic tongue 32 formed on a portion of the side surface of the inner tube 30 and projects from a protruding locking window 22 that opens toward the longitudinal center of the side surface of the outer tube 20, eliminating the inconvenience of the conventional position where the locking projection 33 must be operated near the longitudinal end of the outer tube 20. As a result, a stick-shaped cosmetic container that is compact yet has excellent operability can be provided. [Brief explanation of the drawings]

[0020] The basic configuration of the present invention includes a feeding mechanism 10, an outer cylinder 20, an inner cylinder 30, and a spring 40 (see FIG. 2).

[0021] The feeding mechanism 10 is a mechanism that moves the stick-shaped cosmetic material P up and down by the relative rotation of the sleeve 12 and the hakama tube 11. The stick-shaped cosmetic material P is stored in the sleeve 12 so as to be able to move in and out (see FIG. 1).

[0022] The outer tube 20 is a cylindrical container with a bottom that houses the stick-shaped cosmetic material P housed in the sleeve 12 together with the dispensing mechanism 10 (see FIG. 4). The illustrated outer tube 20 has a rectangular cross section. A storage locking window 21 and a protruding locking window 22 are provided adjacent to each other along the longitudinal direction at the center of the side surface of the outer tube 20 (see FIG. 2). In the illustrated example, the storage locking window 21 and the protruding locking window 22 are formed in a rectangular shape.

[0023] The cross-sectional shape of the outer tube 20 is similar to that of the hakama tube 11, and it is sufficient if it has a flat portion on at least a part of the side surface (see FIG. 1). The hakama tube 11 is housed in the outer tube 20 so as not to be able to rotate. In the illustration, a housing locking window 21 and a protruding locking window 22 are formed in this flat portion (see FIG. 2).

[0024] The inner tube 30 is a cylindrical member with a bottom that is slidably housed within the outer tube 20, and has a housing recess 31 formed therein into which the sleeve 12 is fitted from the tip side to house it (see FIG. 3). In the illustrated example, a spring 40 presses and urges the bottom side of the inner tube 30. After the sleeve 12 is housed in the housing recess 31, when the hakama tube 11 is further pushed in, the inner tube 30 moves and the spring 40 becomes compressed (see FIG. 4).

[0025] Furthermore, an elastic tongue 32 is formed on a portion of the side surface of the inner tube 30, and a locking projection 33 is provided on the outer side of the elastic tongue 32 (see FIG. 7). The illustrated elastic tongue 32 is formed in a band shape along the circumferential direction by horizontally cutting out a portion of the side surface of the cylindrical storage body 34 (see FIG. 9). Because this elastic tongue 32 is formed on the side surface of the cylindrical storage body 34, the elastic tongue 32 does not protrude from the longitudinal end of the inner tube 30 as in the conventional example, and furthermore, the strength of the inner tube 30 is not affected even when the elastic tongue 32 is formed.

[0026] That is, the illustrated inner cylinder 30 comprises a cylindrical storage body 34 forming the storage recess 31, an upper fitting portion 35 formed on the upper end side of the cylindrical storage body 34 and fitting with the inner surface of the outer cylinder 20, and a lower fitting portion 36 formed on the lower end side of the cylindrical storage body 34 and fitting with the inner surface of the outer cylinder 20 (see FIG. 7). Furthermore, a cylindrical storage portion 37 is formed inside the lower fitting portion 36, into which the upper end of the spring 40 fits (see FIG. 3).

[0027] The elastic tongue 32 is formed by cutting out the side surface of the cylindrical storage body 34 between the upper fitting portion 35 and the lower fitting portion 36. Furthermore, the locking protrusion 33 has a wedge-shaped cross section (see FIG. 8). When a stick-type cosmetic material P is stored, the upper surface of the locking protrusion 33 locks with the upper end of the storage locking window 21 of the outer tube 20 (see FIG. 4). From this state, when the locking protrusion 33 is pushed into the outer tube 20 from outside the storage locking window 21, the locked state is released and the inner tube 30 is raised by the pressing force of the spring 40, causing the locking protrusion 33 to protrude from the inside into the protruding locking window 22 (see FIG. 3).

[0028] Furthermore, when the locking protrusion 33 protruding into the protruding locking window 22 is pushed downward, the upper surface of the locking protrusion 33 that has moved from the protruding locking window 22 to the storage locking window 21 locks with the upper end of the storage locking window 21 (see FIG. 5). At this time, by forming the storage locking window 21 and the protruding locking window 22 on the longitudinal center side of the outer tube 20, the locking protrusion 33 is operated on the longitudinal center side of the outer tube 20, making it easy to operate even with a compact-sized outer tube 20 (see FIG. 2).

[0029] A push button 50 is disposed on the outside of the outer tube 20 to push in the locking protrusion 33 (see FIG. 1). The illustrated push button 50 is a rod-shaped member having locking portions 51 on the top and bottom that lock into the storage locking window 21 and the protrusion locking window 22, respectively (see FIG. 5). Furthermore, a release protrusion 52 is provided at a position where the locking protrusion 33 locked into the storage locking window 21 is pushed in from the outside.

[0030] 5, when the release projection 52 is pressed from the outside against the locking projection 33, the elastic tongue 32 rises and the locking projection 33 protrudes into the protruding locking window 22 (see FIG. 6). In the illustration, the upper end of the elastic tongue 32 is locked to the lower end of the locking portion 51 which is locked to the upper end of the protruding locking window 22.

[0031] The spring 40 is an elastic member that is installed on the bottom side of the outer tube 20 and presses against the bottom side of the inner tube 30. The illustrated spring 40 uses a coil spring, and its upper end is fitted into a cylindrical storage portion 37 formed in the lower fitting portion 36 of the inner tube 30, and its lower end is placed on the bottom of the outer tube 20 (see FIG. 3).

[0032] Next, the procedure for using the present invention will be described. First, when storing a stick-shaped cosmetic material P, the tip of the sleeve 12 is inserted into the storage recess 31 of the inner tube 30 while it is stored in the sleeve 12 (see Figure 3). When the hakama tube 11 is further pressed to push the inner tube 30 toward the bottom, the inner tube 30 compresses the spring 40, and the locking protrusion 33 of the elastic tongue piece 32 moves from the protruding locking window 22 to the storage locking window 21 and locks into the upper end of the storage locking window 21 (see Figure 4).

[0033] Next, to use the stick-shaped cosmetic material P, the locking protrusion 33 inside the protruding locking window 22 is pressed in with the release protrusion 52 of the push button 50 to release it (see FIG. 5). This causes the inner tube 30 to be pushed up by the pressing force of the spring 40, and the locking protrusion 33 moves into the protruding locking window 22 (see FIG. 6). In this position, the hakama tube 11 of the dispensing mechanism 10 protrudes from the outer tube 20 (see FIG. 2). The hakama tube 11 is grasped to remove the sleeve 12 from the storage recess 31, and the dispensing mechanism 10 is used to dispense the stick-shaped cosmetic material P from the sleeve 12 (see FIG. 1).

[0034] The configuration of the present invention is not limited to the illustrated example, and design changes can be freely made within the scope of the present invention. In addition, the present invention can be used to store stick-shaped cosmetics such as lipstick, lip balm, and stick foundation, as well as stick-shaped tools required for makeup such as lip brushes, face brushes, and cosmetic puffs.
