Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick-shaped cosmetic container, and more particularly, to a stick-shaped cosmetic container in which only a stick-shaped cosmetic filled therein can be replaced.

[0002]

2. Description of the Related Art A stick-shaped cosmetic container in which a stick-shaped cosmetic filled therein comes out by rotating an outer cylinder is used for cosmetics such as lipstick, lip balm, concealer and the like because of ease of use. Widely used as containers.

A conventional stick-shaped cosmetic container comprises, for example, as shown in FIG. 1, an outer cylinder 10, a sleeve 2, and an inner plate 7 filled with a stick-shaped cosmetic. In FIG. 1, the right view is a cross-sectional view in which only the inner plate 7 is substantially shown (however, the stick-shaped cosmetic is not shown), and the left-hand view is a cross-sectional view in which only the sleeve 2 is removed. .

Of these, small projections 8 are provided on the lower portion of the outer surface of the inner plate.
However, the inner plate guide groove 3 is provided in the sleeve 2, and
A screw 11 is cut on the inner surface of the outer cylinder 10. And
The small projection 8 of the inner plate 7 moves up and down along the rotation of the screw 11 of the outer cylinder 10 along the inner plate guide groove 3 of the sleeve 2, and a mechanism in which the stick-shaped cosmetic material appears and disappears in accordance with the rotation.

As described above, the small projections 8 of the inner plate 7 move up and down according to the rotation of the outer cylinder 10 along the inner plate guide grooves 3 of the sleeve 2.
Since the inner plate 7 eventually falls off the sleeve 2, the movement of the small projections 8 of the inner plate 7 needs to be limited to a certain range. For this reason, in the conventional stick-shaped cosmetic container, the inner plate 7 is prevented from falling off by closing both ends of the inner plate guide groove 3 and not cutting the screw 11 on the inner surface of the outer cylinder to the end.

[0006] The conventional stick-shaped cosmetic container having the above structure has no problem when it is used up, but it is very difficult to use it when refilling or replacing the container. That is, since the inner plate is configured not to fall off, it is necessary to replace the inner plate itself after disassembling the cosmetic container once.

In recent years, with the spread of resource saving and recycling activities, cosmetics that can be refilled or replaced have been favored. In fact, it was not yet available that could only be exchanged.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a stick type cosmetic container which can be easily refilled and exchanged, but which has no problem of falling off of the inner plate during normal use. Providing is the subject.

[0009]

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, by utilizing the characteristic that the inner plate is moved up and down by a screw cut on the inner surface of the outer cylinder, The present invention was completed with the idea that both refilling and replacement and prevention of falling off of the inner plate can be achieved at the same time.

That is, the present invention includes an outer cylinder, a sleeve, and an inner dish filled with a stick-shaped cosmetic, wherein a small projection provided on the inner dish is guided by an inner dish guide groove provided on the sleeve, and The small projection moves up and down by the screw cut on the inner surface, and in the stick-shaped cosmetic container for allowing the stick cosmetic filled in the inner dish to come and go, the lower end of the inner dish guide groove provided on the sleeve is opened. In addition, this is a stick-shaped cosmetic container provided with a concave portion for accommodating a small projection below the inner plate guide groove.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings showing one embodiment of the present invention, but the present invention is not limited thereto.

FIG. 2 is a drawing showing the structure of the stick-shaped cosmetic container of the present invention. The right-hand drawing is a cross-sectional view showing only the inner plate, and the left-hand drawing is only the sleeve. It is sectional drawing of the state which carried out (however, stick-shaped cosmetics are not shown). In the figure, 1 is a stick-shaped cosmetic container,
2 is a sleeve, 3 is an inner plate guide groove, 4 is a small protrusion storage recess, 5 is a guide groove end, 6 is an inner plate stopper, 7 is an inner plate, 8 is a small protrusion, 9 is a drop-out prevention protrusion, and 10 is an outer cylinder. , 11
Indicates a screw.

The stick-shaped cosmetic container 1 of this embodiment is
Basically, as described with reference to FIG.
, A sleeve 2 and an inner plate 7 filled with a stick-shaped cosmetic, but differ in the shape of the sleeve and the point that the screw 11 on the inner surface is completely cut off.

That is, the sleeve 2 used in the present embodiment
FIG. 3 shows that the sleeve 2 is open at the lower end 5 of the inner dish guide groove 3, the small projection storage recess 4 is provided below the inner dish guide groove 3, and the sleeve 2 2 is different from the sleeve used in the conventional stick-shaped cosmetic container in that the inner plate stopper 6 is provided at the lower part of the container.

FIG. 4 shows a sectional shape of the inner plate 7 used in combination with the above. This inner dish has a cylindrical shape with only a sharp tip, and at the boundary between the sharp part and the cylindrical part,
The drop prevention projections 9 are provided to prevent the filled cosmetic stick from falling off. Further, a small projection 8 having a small cylindrical shape is provided below the cylindrical portion.

In the stick-shaped cosmetic container 1 of the present invention, the lower end portion 5 of the inner plate guide groove 3 is open, and the inner tube 10 is cut even though the screw 11 of the outer tube 10 is completely cut. The mechanism by which the plate 7 does not fall off from the lower part is as follows.

That is, by turning the outer cylinder 10 of the stick-shaped cosmetic container 1 in the state of FIG. 2 to the left while holding the sleeve 2, the screw 11 cut inside the outer cylinder 10 A force is applied to the small projection 8 in the lower left direction. However, since the small projection 8 is guided by the inner groove guide groove 3 of the sleeve 2, it cannot move to the left, but only moves downward.

FIG. 5 shows the state of this movement. In the figure, a small projection 8 indicated by a wavy circle is given a downward leftward force by a screw 11 indicated by an oblique line, but the leftward movement is suppressed by the inner plate guide groove 3. From below, it moves downward along the left end of the inner plate guide groove 3. FIG. 6 shows the intermediate stages in the same manner as FIG.
(However, the outer cylinder part is omitted in the drawing on the right side).

By rotating the outer cylinder to the left in this manner, the small projection 8 is pushed down, and the inner plate 7
The inner plate itself also goes down, but the small projection storage recess 4 is provided in a portion near the lower end 5 of the inner plate guide groove 3, so that the leftward force suppressed by the left end of the inner plate guide groove 3 until then is reduced. That is, the small projections 8 are stored in the small projection storage recesses 4, not at the positions indicated by the two-dot chain lines in FIG. 5. Even if the outer cylinder 10 is further rotated, the small projections 8 are suppressed by the small projection storage recesses 4, so that they cannot move further downward. FIG. 7 shows this state in the same manner as FIG. 2 (however, the outer cylinder part is omitted in the right-hand drawing).

Further, when the inner plate stopper 6 is provided at the lower end of the sleeve 2, the inner plate stopper 6 acts as a resistance to the descending inner plate 7. It is easy to enter the storage recess 4. The inner plate stopper 6 can be provided by, for example, a method of forming a small convex protrusion inside the lower end of the sleeve 2.

Next, in order to draw out (move upward) the stick-shaped cosmetic from the stick-shaped cosmetic container 1 in the state of FIG. 7, the outer cylinder 10 is rotated to the right in the opposite manner as before. The small projections 8 housed in the small projection housing recesses 4 receive a force in the upper right direction by the force of the screws 11 provided in the outer cylinder 10, and move upward along the right end of the inner plate guide groove 3. It moves, and the inner plate 7 rises accordingly.

With such a mechanism, the inner plate 7 moves up and down in the sleeve 2 without falling down. When the stick-shaped cosmetic material filled in the inner plate 7 is used up, the following is performed. This makes it easy to replace the inner plate.

First, the inner plate 7 is moved to the lowermost position, and the small projections 8 are stored in the small projection storage recesses 4. Next, the small projection 8 is moved from the small projection storage recess 4 to a position indicated by a two-dot chain line circle in FIG. 5 by an appropriate means such as use of a jig. When moved to this point, since the lower end portion 5 of the inner plate guide groove 3 is open, the used stick-shaped cosmetic can be easily taken out together with the inner plate 7. Then, the new stick-shaped cosmetic filled in the inner dish is inserted from the bottom of the stick-shaped cosmetic container 1 and the small projections 8 are again stored in the small projection storage recesses 4 by using a jig or the like. The replacement of the cosmetic is completed.

The stick-shaped cosmetic container 1 of the present invention
In the above, since the stick-shaped cosmetic is taken in and out from the bottom, it is necessary that the bottom is opened to some extent, but since such a state is not good, the bottom 12
May be formed in a shape as shown in FIG. 8, for example, and a seal may be attached here in a normal use state. The size of the hole in the bottom portion 12 may be slightly larger than that of the inner plate 7, and the notch 13 may correspond to the small projection 8.

If the sticker attached to the bottom portion 12 has a product number, a color tone, etc., it is convenient for purchasing a replacement stick-shaped cosmetic.

The stick-shaped cosmetic container 1 of the present invention is the same as the conventionally provided stick-shaped cosmetic container except for the shape of the sleeve 2 and the point that the screw 11 of the outer cylinder is completely cut. , Size, shape, etc. can be prepared. That is, the tip of the inner plate may not be sharp but may have another shape, and various metals and plastics may be used as the material of the sleeve 2, the inner plate 7, and the outer cylinder 10. Can be. Further, the outside of the outer cylinder 10 may be covered or covered with a metal, or may be coated by various methods. As for the material, any material that can maintain its shape, such as paper and ceramics, can be used in addition to metal and plastic.

[0027]

The stick-shaped cosmetic container of the present invention does not cause the inner plate to fall off when used, but when the stick-shaped cosmetic is completely used, it can be easily replaced by using a simple jig or the like. You can do it.

Accordingly, lipstick, lip balm,
It can be advantageously used in cosmetics such as concealer, skin lightening stick, sunscreen stick and the like.
