[0001]
[Industrial application fields]
The present invention relates to molding and receiving of a cosmetic material by cooling and solidifying the molten cosmetic material injected and filled into the container body, with the storage tube portion of the inner cylindrical body of the container body and the tray body being part of the mold surface. The present invention relates to a stick-shaped cosmetic material feeding container that achieves assembly at the same time.
[0002]
[Prior art]
Forming a detachable functional part at the upper end, extending the outer cylindrical body with a straight cylindrical shape with a thread groove on the inner peripheral surface, and the upper half of the storage cylinder that also functions as a cosmetic mold surface, Insert a lower half guide cylinder with a vertically long guide hole, and attach it to the outer cylinder so that it can rotate but cannot be pulled out. A threaded protrusion that protrudes through the guide hole and engages with the thread groove of the outer cylinder protrudes, and a holding protrusion for holding cosmetics is provided on the inner peripheral surface so that the inner cylinder can be displaced up and down. Consists of a linear cylindrical saucer body and a top cylindrical cap body that opens and closes the upper end opening of the storage cylinder part of the inner cylinder by attaching to and detaching from the attachment / detachment function part of the outer cylinder, and is positioned at the lower limit. The molten cosmetic material poured and filled from the filling port, which is the lower end opening of the outer cylinder, is cooled by using the tray body and the storage cylinder of the inner cylinder as a part of the mold surface. It solidified, assembled to the molding at the same time as pan of cosmetics, that is, bottom-filled feeding container to achieve the assembly of the propelling container are known.
[0003]
As shown in FIG. 8 , this bottom-filling-type delivery container has a container body 1 composed of an outer cylinder body 2, an inner cylinder body 10, and a saucer body 17, with the saucer body 17 positioned at the lower limit, The container body 1 is inverted while the upper end opening of the storage cylinder portion 11 of the body 10 is sealed with the mold cap 23, and the inner cylinder 10 is stored from the filling port (the upper end in FIG. 8 ) at the lower end of the outer cylinder 2. By pouring and filling cosmetic A heated and melted into the molding space formed by the cylindrical portion 11, the tray 17 and the mold cap 23, the molten cosmetic A filled and filled is cooled and solidified as it is. Is formed into a predetermined shape, and at the same time, a stable and strong assembly of the cosmetic material A to the saucer body 17 is achieved. In addition, the filling port of the outer cylinder 2 is sealed by sticking a seal label after the injection filling molding of the cosmetic material A is completed.
[0004]
Formed with the storage cylinder part of the inner cylinder, the tray body, and the mold cylinder (corresponding to the mold cap of the bottom-filling-type delivery container) assembled to the upper end of the inner cylinder with respect to this bottom-filling-type delivery container The upper filling mold feeding container for injecting and filling the molten cosmetic material from the upper end opening of the mold cylinder into the molding space to be cooled and solidified has a saucer body with a bottomed cylindrical structure. The ability to seal the space, that is, the space below the cosmetic storage space, is high, which is advantageous for airtight storage and holding of a bar-shaped cosmetic containing a volatile component.
[0005]
As described above, the top-filling-type feeding container is superior to the bottom-filling-type feeding container in terms of hermetic sealing of the cosmetic storage space, and is advantageous in that the structure of the sealing function portion can be simplified. However, there is a specific cooling and solidification form of the melted cosmetic filled in the molding space, that is, a specific cooling and solidification form in which a depression is formed in the center part of the upper end surface due to the volumetric shrinkage change accompanying cooling and solidification For this reason, the usage amount of the bottom-filling type feeding container is much larger than the usage amount of the top-filling type feeding container.
[0006]
In other words, the bottom-filling type feeding container allows the tip portion of the cosmetics, which is the main body of the product, to be easily and reliably and suitably molded into the desired external shape by the mold cap, whereas the top-filling type feeding container In the case of a container, after achieving the cooling and solidification of the cosmetic, it is necessary to remove the cosmetic tip according to the desired shape, or to re-form the post-treatment. It may not always be as good as the desired or bottom-filled delivery container, and in many cases it is simply a bar-shaped cosmetic that simply cuts and removes the tip of the cosmetic at an angle. The shape of the appearance is not good.
[0007]
[Problems to be solved by the invention]
In this way, the bottom-filling type dispensing container is manufactured in a large amount compared to the top-filling type dispensing container, so that the production unit price can be made sufficiently low for the one-product mass production, In the case of the top-filling type delivery container, there is a problem that the production unit price is high because it is produced in a small number of one type.
[0008]
Also, since the bottom filling type feeding container and the top filling type feeding container are completely different in the structure of the tray body, they cannot be transferred to each other at all, and therefore prior to cosmetic production, It is necessary to prepare the bottom-filling-type feeding container and the top-filling-type feeding container as many as necessary individually, which makes it difficult to manage the parts and to prepare a large number of spare parts in advance. There was a problem that there was.
[0009]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and it is technically possible to use a bottom-filling type feeding container produced in large quantities as an upper-filling type feeding container. It is an object of the present invention to achieve a significant reduction in the manufacturing unit price of the feeding container and to simplify the handling of the feeding container on the cosmetic production side.
