DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dish member for directly holding a lipstick or the like of a stick-shaped cosmetic storage container such as a lipstick, in which a capsule for forming a lipstick is fitted on an upper portion of the dish member when the lipstick is filled. After the container is inverted, the lipstick heated and melted is poured into the capsule and the dish member from the bottom of the dish member, cooled and solidified, and the capsule is removed from the dish member, thereby filling the lipstick with a stick-shaped cosmetic storage. The present invention relates to a stick-shaped cosmetic storage dish member of a container.

[0002]

2. Description of the Related Art Conventionally, as a dish member of a stick-shaped cosmetic storage container in which a lipstick is filled, a lipstick is located inside a lipstick filled on the inner surface of the dish member in order to prevent the lipstick from falling off the dish member. Is provided with a locking projection,
In the conventional stick-shaped cosmetic storage container, the locking projection is provided horizontally in the dish member as shown in Japanese Utility Model Publication No. 3-46643, or disclosed in JP-A-8-112140.
As shown in the figure, the thing which made the waveform over the whole circumference is known.

[0003]

In the dish member of the conventional stick-shaped cosmetic storage container constructed as described above, when the lipstick heated and melted is poured into the capsule and the dish member, bubbles are formed on the inner wall of the capsule and the dish member. It is easy to remain, especially in the locking projection on the inner surface of the dish member, the flow of the molten lipstick is hindered by the locking projection, so that air bubbles are likely to remain, whereby the lipstick is easily broken inside the dish member,
There was a disadvantage that the lipstick would fall off the container.

The present invention has been made in view of the above-mentioned conventional drawbacks,
An object of the present invention is to provide a dish member of a stick-shaped cosmetic storage container in which air bubbles do not remain on the locking projections on the inner surface of the dish member during lipstick filling.

[0005]

In order to solve the above-mentioned problems, the present invention is formed in a cylindrical shape having both ends opened, at least one engaging pin is formed on an outer peripheral portion, and an inner surface is formed on the inner surface. Means is used in which a plurality of pairs of C-shaped or inverted C-shaped locking projections are formed.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A plurality of pairs of locking projections formed on the inner surface of a dish member have a C-shape or an inverted C-shape, so that the flow of the molten lipstick poured into the inside of the dish member is obstructed. No air bubbles remain on the locking projections.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. In the first embodiment of the present invention shown in FIGS. 1 to 4, reference numeral 1 denotes a generally known stick-shaped cosmetic storage container, and the stick-shaped cosmetic storage container 1 is a hakama member 2 having a lid fitting portion 8 formed on an upper portion thereof. And a cylindrical inner cylindrical member 4 having a lower end portion inserted and fixed in the hakama member 2 and an upper axial direction slit groove 3 formed therein, and the outer periphery of the slit groove 3 of the inner cylindrical member 4 is turned around. A spiral member 6 having a spiral groove 5 formed therein so as to movably cover, an outer cylindrical member 7 covering the outer periphery of the spiral member 6, and a plate member 9 formed to be vertically movable in the inner cylindrical member 4; The split groove 3 of the inner cylinder member 4 and the spiral groove 5 of the spiral member 6 formed on the dish member 9
And an engaging pin 10 which engages with the engaging pin.

Reference numeral 11 denotes a filling port which penetrates through the bottoms of the hakama member 2 and the inner cylinder member 4. The filling port 11 is used for filling the stick-shaped cosmetic storage container 1 with the lipstick 12 as shown in FIG. The filling method is as follows. After the capsule 14 having the appearance shape of the lipstick 12 is fitted to the upper part of the dish member 9, the lipstick storage container is inverted, and the lipstick filling nozzle 13 passes through the filling port 11 and the lipstick. The lipstick 12 heated and melted by the filling nozzle 13 is filled into the inside of the dish member 9 and the capsule 14 fitted to the upper end of the dish member 9.

Reference numeral 15 denotes a pair of locking projections formed in the dish member 9. The pair of locking projections 15 are buried in the filled lipstick after the dish member 9 is filled with lipstick. Is positioned relatively above the inner surface of the plate member 9 so that
The shape is a so-called C-shape in which one pair is formed by two projections each having an inclined surface on the left and right sides, and a plurality of pairs, three pairs in the description of the present embodiment, are formed on the inner surface of the plate member 9. .

Further, the pair of locking projections 15 are provided with cutouts 16 between the left and right projections, so that no bubbles remain inside the molten lipstick 12 poured from the bottom of the plate member 9 and the lipstick 12 Of the molten lipstick 12 does not hinder the flow of the molten lipstick 12 because the pair of locking projections 15 are not connected to each other but are independent of each other.

Reference numeral 17 denotes a lid which is detachably fitted to the lid fitting portion 8 of the hook member 2.

[0012]

Next, different embodiments of the present invention will be described. In these descriptions, the same components as those of the first embodiment of the present invention are denoted by the same reference numerals, and redundant description will be omitted.

The second embodiment of the present invention shown in FIGS. 5 to 7 is mainly different from the first embodiment of the present invention in that:
A pair of locking projections 15A formed on the inner surface of the plate member 9A, and the pair of locking projections 15A are formed in an inverted C-shape. The storage container 1A may be used.

In the above description, the dish member 9 is set in advance in the stick-shaped cosmetic storage container 1 when the lipstick 12 is filled. However, the present invention is not limited to this. After filling, the dish member 9 may be set in the stick-shaped cosmetic storage container 1.

[0015]

Since the present invention is configured as described above, it has the following effects.

By virtue of the action of the C-shaped locking projection, the flow of the molten lipstick is not hindered by the locking projection inside the dish member, so that no air bubbles are generated inside the lipstick, whereby the lipstick is displaced by the dish member. It does not break inside or the lipstick falls out of the container.
