Description

[Detailed Description of the Invention] The present invention relates to a rod-shaped cosmetic dispensing container that is a cartridge type cosmetic product.

If this type of container is used for storing cosmetics in a cartridge type, when the cosmetics are used up, only the inner plate that holds the cosmetics can be replaced, and the container body can be used as is, which is both economical and convenient.

In view of this point, an object of the present invention is to provide a rod-shaped cosmetic dispensing container in which the inner plate is configured as a cartridge type with a simple mechanism, and the consumption of cosmetics can be dealt with by replacing only the inner plate.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the attached drawings, 1 is a main cylinder in which an intermediate cylinder 3 with an outer diameter slightly smaller than the lower cup-shaped base cylinder part 2 stands upright, and 4 is a main cylinder that fits on the outer surface of the intermediate cylinder 3 of the main cylinder 1. and 5 is a receiving tray of a cylindrical body that is fitted into the middle cylinder 3 and moves up and down inside the middle cylinder 3.

The mechanism for dispensing cosmetics in this type of container is very well known, so to briefly explain the mechanism, the middle cylinder 3 of the main cylinder 1
There are longitudinally elongated saucer guide holes 6, 6 on both sides from the bottom end to the top, and two screw grooves 7, 7 that go around the inner circumferential surface of the rotary cylinder 4 from the bottom to the top. It is formed symmetrically, and the saucer guide holes 6, 6 of the inner cylinder 3 are provided on both sides of the outer surface of the saucer 5.
There are protrusions 8, 8 which are respectively engaged with the threaded grooves 7, 7 of the rotating cylinder 4 through the protrusions 8, 8.

Therefore, hold the rotary cylinder 4 with one hand, pinch the base cylinder part 2 of the main cylinder 1 with the fingers of the other hand, and rotate the main cylinder 1, for example clockwise, relative to the rotary cylinder 4 via the base cylinder part 2. When the saucer 5 is rotated to
Since it is engaged with, it will spiral. However, the protrusions 8, 8 are simultaneously connected to the saucer guide hole 6,
6, so in the end this saucer 5 is connected to the main cylinder 1.
The relative rotation of the rotary tube 4 causes the container to move straight upward, and therefore, if the tray 5 holds cosmetics, the cosmetics are delivered upwardly and externally from the upper opening of the middle tube 3. If the relative rotational movement between the main cylinder 1 and the rotary cylinder 4 is in the opposite direction, the cosmetics will be drawn into the interior by an operation opposite to the above. FIG. 2 shows the cosmetics being dispensed, and FIG. 1 the cosmetics being inserted.

Here, in the present invention, a cylindrical inner plate 9 is removably engaged with the saucer 5, and this inner plate 9 is configured to hold the bar-shaped cosmetic 10, and the saucer guide hole 6 of the middle tube 3, The lower part of the inner circumferential surface except for 6 is a step-shaped inward thick part 11, and the upper end of this thick part 11 is
An upward stepped portion 12 is formed which is substantially flush with the upper end surface of the saucer 5 when the saucer 5 is retracted downward.

That is, a downward step 13 is formed on the inner circumferential surface of the lower part of the saucer 5, and a downward step 14 is formed by protruding the upper part of the inner plate 9, and an engaging protrusion is formed on the outer surface of the lower part. Therefore, in the assembled state in which the inner plate 9 is inserted into the saucer 5, the upper downward step portion 14 engages with the upper end surface of the saucer 5, and at this time, the lower engaging protrusion 15 is the downward step 13 of the saucer 5
The inner plate 9 and the saucer 5 are firmly engaged with each other. In this case, the upper downward step 14
has a large protruding length, and therefore the protruding ridge 14 protrudes outward (toward the middle cylinder 3 side) from the outer surface A of the saucer 5. In addition, since the projecting length of the protrusions 8, 8 is determined so that the saucer 5 can be moved up and down inside the thick part 11 of the middle cylinder 3, when the middle cylinder 3 without the thick part 11 is moved up and down, its outer surface An appropriate space is formed between the inner peripheral surface of the middle cylinder 3 and the inner circumferential surface of the middle cylinder 3. The cosmetics holding structure of the inner tray 9 may be arbitrary, and in the illustrated example, several vertical strips 16 are protruded from the inner surface of the inner tray 9 at appropriate intervals in the circumferential direction to make the inner peripheral surface uneven, thereby solidifying the cosmetics 10. An example is shown.
In addition, 17 indicates a cosmetic molding case, and cosmetics 1
0 attaches this case 17 to the inner plate 9, coats the inner surface with a mold release agent, fills the case 17 with cosmetics and solidifies it in an upside down state, and removes the case 17 when it is attached to a container.

In the above configuration, the replacement of the inner plate 9 is performed as follows. FIG. 1 shows a state in which cosmetics 10 have been put into the container as specified, and in this state, the downward step 1 at the top of the inner tray 9
4 is engaged with an upward step portion 12 of a thick wall portion 11 of the middle cylinder 3. From this state in FIG. 1, the tray 5 is further forcibly moved downward, that is, in the cosmetics feeding direction. Then, the saucer 5 enters the base cylindrical portion 2 and moves downward, but the inner tray 9 moves upward into the stepped portion 1.
Therefore, as shown in FIG. 3, the lower engaging protrusion 15 is disengaged from the downward step 13, and the inner plate 9 is disengaged from the receiving plate 5.
Therefore, this time, move the saucer 5 in the cosmetics feeding direction.
In other words, all you have to do is move it upwards. Then, as shown in FIG. 4, the inner plate 9 protrudes outward, and since it is disengaged from the saucer 5 at this time, it can be easily removed by hand. Thereafter, the inner tray 9 filled with new cosmetics is forcibly inserted into the tray 5 to firmly engage the two. In addition, 19 is an outer cover.

According to the present invention, the engagement of the inner tray 9 with respect to the tray 5 is released by simply advancing the normal cosmetics loading operation a little further without requiring any special operation, and therefore the cosmetics loading operation is performed thereafter. Since all that is required is to take out the inner plate 9 to the outside and replace it, the replacement operation is extremely simple and hassle-free. Moreover, in terms of structure, an inner plate 9 is provided which is engaged and assembled with the receiving plate 5, and the downward stepped part 14 of the inner plate 9 is engaged with the upward stepped part 12 on the inner cylinder 3 side at the specified retracted position, and the inner plate 9 is not retracted further downward. It is simple because it only needs to be made immovable, and therefore can be provided at low cost. Further, as described above, the cosmetic product 10 is filled and fixed in the inner tray 9 using the molding case 17, and the case 17 is removed when it is attached to the container, but at this time, the mold release agent is not sufficiently applied to the case 17. If the cosmetic product 10 is loose or partially damaged, the cosmetic product 10 may break, but according to the present invention, such cases can be easily dealt with.
