Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a bar-shaped cosmetic container.

[Conventional technology]

Conventionally, containers for storing bar-shaped cosmetics such as lipsticks have often been used in which the bar-shaped cosmetic is housed in an inner tray that is raised and lowered by a feeding mechanism. Many proposals have been made, such as in JP-A-58-11417, JP-A-58-11418, and JP-A-54-41818, which are configured to be attached to a dispensing container having a mechanism from above.

[The problem that the idea aims to solve]

However, since these containers pass through a threaded protrusion protruding from the side surface of the inner plate, a notch is exposed at the top end, resulting in an unsightly container.

This type of container also had the disadvantage that it was impossible to tell how it was rotating and being fed unless an inner plate was attached.

[Means to solve problems]

An inner plate 2 that accommodates and holds a rod-shaped cosmetic 1 has a slit 3 carved therein which is elastic and bends inward, and a leg cylinder 4 having a threaded protrusion 5 protruding from its lower outer surface hangs down. .
The sleeve 6 into which the inner plate 2 is slidably inserted vertically is passed through the through guide groove 7 through which the threaded projection 5 of the leg tube 4 passes, and further through the through guide groove 7.
The upper inner wall has a concave guide groove 8 that continues to the upper end.
is engraved on the inner wall. The tail plug 11 fixed to the lower end of the sleeve 6 has a flange 10 projecting toward the side wall of the sleeve 6 . The threaded engagement protrusion 5 of the leg tube 4 that has passed through the penetration guide groove 7 of the sleeve 6 is screwed into a spiral groove 13 that is threaded into the spiral tube 12. The rotation operation cylinder 14 into which the spiral cylinder 12 is inserted and fixed holds the collar part 10 of the tail plug 11 between the bottom surface and the lower end of the spiral cylinder 12, so that the sleeve 6 can be freely rotated. Hold it in place so that it cannot be removed. This rotation operation tube 1
The inner cylinder 17 fixed to the inner cylinder 4 is provided with an insertion part 16 into which the lid 15 is removably inserted. The present invention has the above configuration.

Further, it is preferable to sandwich a rotation resistor 9 on the bottom surface of the tail plug 11 so as to be in sliding contact with the bottom surface of the rotation operation cylinder 14.

[Effect]

In normal use, the threaded protrusion 5 of the leg cylinder 4 passes through the through guide groove 7 of the sleeve 6, and the rotation operation cylinder 14 passes through the through guide groove 7 of the sleeve 6.
Since it is threadedly engaged with the spiral tube 12 that is inserted and fixed in the inner plate 2, by holding the sleeve 6 and rotating the rotary operation tube 14, the bar-shaped cosmetic 1 that is fitted and held in the inner plate 2 can be moved into the sleeve. 6 It is configured to appear and retract from the tip.

In addition, when attaching the inner plate 2 holding the bar-shaped cosmetic material 1 to the container body, when the stem tube 4 is bent inward and inserted, the threaded protrusion 5 engages with the guide groove 8 and slides. I can move. When the inner plate 2 is lowered and inserted into the sleeve 6, the threaded protrusion 5 enters the penetration guide groove 7, and when the sleeve 6 and the rotation operation cylinder 14 are rotated, the elastic leg cylinder 4 The screwing protrusion 5 which is provided on the bottom screws into the spiral groove 13, and the assembly can be completed by lowering it down to the lower end.

〔Example〕

The inner plate 2 that accommodates and holds the bar-shaped cosmetic material 1 has a stem tube 4 in which a slit 3 that elastically bends inward is carved.
is hanging down. A threaded projection 5 is provided protruding from the lower outer surface of the leg tube 4.

The sleeve 6 into which the inner plate 2 is vertically slidably inserted has a through guide groove 7 vertically formed from the lower part thereof, through which the threaded projection 5 of the leg tube 4 passes. Further, a concave guide groove 8 is carved in the upper inner wall of the through-hole guide groove 7 and continues to the upper end. The lower end of this sleeve 6 is equipped with a rotation resistor 9 made of rubber on the lower surface,
A flange 1 protruding toward the side wall of the sleeve 6 on the outer periphery of the lower end
A tail plug 11 having a circumference of 0 is fixed thereto.

The helical tube 12 into which the lower portion of the sleeve 6 is rotatably inserted has a helical groove 13 into which the threaded protrusion 5 of the leg tube 4 passing through the guide groove 7 of the sleeve 6 is screwed. The lower end of this spiral tube 12 is in contact with the flange 10 of the tail plug 11. Said tail plug 1
The flange 10 of 1 is connected to the bottom surface of the rotary operation tube 14 and the spiral tube 1.
2, and holds the sleeve 6 rotatably but not removably.

Note that the rotation resistor 9 provided on the tail plug 11 is held between the rotation operation tube 14. Furthermore, a middle cylinder 17 having an insertion part 16 into which a lid body 15 is removably inserted is fixedly attached to the rotary operation cylinder 14. The upper end of this middle cylinder 17, that is, the insertion part 16 is connected to the spiral cylinder 12.
covering the top.

As shown in FIG. 3, it is preferable to cover the cosmetic stick 1 with a cosmetic stick cover 18 until it is attached to the container body. In addition, in order to prevent the leg tube 4 on which the threaded protrusion 5 protrudes from bending inward and detaching from the through-hole guide groove 7 after installation, the gap between the guide groove 8 and the through-hole guide groove 7 is removed as shown in FIG. The lower end of the guide groove 8 may be made shallower as shown in FIG. 5, and the step 19 of the penetrating guide groove 7 may be made larger. It is preferable to take measures such as placing the tail cover 20 to be inserted into the leg tube 4 on top and inserting it into the lowered leg tube 4 to prevent the leg tube 4 from bending again.

[Effect of idea]

As described above, in the present invention, when installing the inner plate 2 in which the bar-shaped cosmetic material 1 is fitted and held, the leg tube 4 is bent and the threaded protrusion 5 is engaged with the guide groove 8 and inserted. This configuration allows assembly by a simple operation, and by simply forming a slightly concave guide groove 8 in the inner wall of the sleeve 6, without the need for a cutout into which the threaded protrusion 5 can penetrate. In other words, Special Public Interest Publication in 1989-
As seen in Japanese Patent No. 10804, there are some that are inserted from the bottom, but it is difficult to align the threaded protrusion 5, especially when it is impossible to insert from above the sleeve 6, but this problem is solved by the guide groove 8. .

Furthermore, in the present invention, in view of the fact that the feeding condition cannot be known unless the inner tray 2 that holds this type of bar-shaped cosmetic material 1 is attached, the present invention provides a rotational resistance between the tail plug 11 and the rotational operation tube 14 in advance. The structure can be such that the body 9 is sandwiched between the body 9 and rotation resistance can be provided.
