Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drum body for storing cosmetics that is assembled into a compact container. More specifically, the present invention relates to a drum body for storing cosmetics that is assembled into a compact container. The purpose of this invention is to expand the dimensional range of application, and to strengthen the assembly into compact containers.

Various compact containers have been used in the past, and cosmetics are stored in these compact containers in a drum tray made of thin metal plate in the shape of a short cylinder with a bottom. This was achieved by assembling it inside a compact container.

This is because the cosmetics used in this type of compact container are shaped in a special way and require the aforementioned drum tray, and the cosmetics that are shaped into a certain shape are extremely fragile. This is because it is extremely difficult to remove it from the drum tray and handle it alone.

In this way, compact containers absolutely require a drum tray in order to mold the cosmetics into a certain shape and store them inside the compact container. Due to physical strength and dimensional regulations, it is formed from a thin metal plate into a short cylindrical shape with a bottom.

As described above, since this drum plate is made of a thin metal plate, it was supposed to be molded by a molding method such as impact molding or press molding.

Regardless of the method used to form this drum plate, post-processing was required to remove burrs formed on the open end of the cylindrical wall by cutting, etc. .

Further, in order to be able to be firmly assembled into a compact container without forming an unsightly gap, it was necessary to mold the container with high dimensional accuracy.

Furthermore, once formed, the drum plate cannot be used at all for compact containers in which the required dimensions and shape of the drum plate to be assembled differ even slightly.

The present invention was devised to solve the drawbacks and problems of the conventional examples described above, and includes a lip body made of synthetic resin for a drum body made of a thin metal plate.
It is integrally attached to at least the upper end surface and the outer peripheral surface of the main body in a state where they are opposed to each other, and the height or outer diameter of the drum body as a whole and the thickness of the mouth rim body are set appropriately. The new value can be set by

Embodiments of the present invention will be described below with reference to the drawings.

The cosmetic storage drum body 2 according to the present invention is assembled into a compact container 1, and includes a main body 3 made of a thin metal plate formed into a short cylindrical shape with a bottom, and at least a cylindrical wall 5 of the main body 3. It is comprised of a lip body 7 made of metal resin that is integrally fixed in a form that covers the upper end surface and the outer circumferential surface.

The main body 3 made of thin metal plate has a short cylindrical shape with a bottom, which has a bottom plate 4 and a low cylindrical wall 5 erected from the peripheral edge of the bottom plate 4, like a conventional drum plate, and is impact molded. However, unlike conventional drum plates, there is no post-processing of the opening edge, and after impact molding or press molding, It remains cut into single pieces.

The lip body 7 is molded from a relatively soft synthetic resin material, and is integrally fixed to the cylindrical wall 5 of the main body 3 so as to cover at least the upper end surface and outer peripheral surface of the cylindrical wall 5 .

The means for integrally fixing the mouth rim 7 to the main body 3 is not particularly limited, and for example, in the embodiment shown in FIG. 3, the main body 3 and the mouth rim 7 are molded completely separately. The fourth figure shows the case where the two were ultrasonically welded after being fitted and assembled.
In the embodiment shown in FIGS. 5 and 5, the main body 3 is a part of a mold and the lip body 7 is insert-molded.

In this way, the lip body 7 is positioned facing at least the upper end surface and the outer circumferential surface of the cylindrical wall 5 of the main body 3, so the height and outer diameter of the drum body 2 are ultimately determined by this. This is set by the lip body 7.

In the case of the embodiment shown in FIG. A gap 12 is formed between the outer wall portion 9 of the lip body 7 and the cylindrical wall 5 of the main body 3.

This gap 12 functions not only to reduce the amount of synthetic resin material consumed for molding the lip body 7, but also to make this outer wall portion 9 more easily elastically deformable.

In the case of the embodiment shown in FIG.
and an outer wall portion 9, and an engaging circumferential groove 6 is provided on the outer circumferential surface of the cylindrical wall 5 of the main body 3 so that the lip body 7 can be more firmly fixed to the main body 3. .

In the case of the embodiment shown in FIG. 4, since the outer wall portion 9 of the mouth rim body 7 is located in close contact with the entire outer circumferential surface of the cylinder wall 5, elastic deformation of the outer wall portion 9 is prevented. Drum body 2 that can be compensated by
The dimensional tolerance is much smaller than that of the embodiment shown in FIG.

The illustrated embodiment in FIG. 5 is the same as the illustrated embodiment in FIG.
This shows an intermediate embodiment between the illustrated embodiment and the illustrated embodiment.
A gap 12 is formed between the lower part of the outer wall part 9 of the mouth rim body 7 shown in FIG. Thus, a strong drum body 2 assembled to the compact container 1 is provided.

That is, in the case of the embodiment shown in FIG.
By forming the lower part of the outer wall part 9, the lower part of the outer wall part 9 is made elastically deformable, and a part of the compact container 1 is engaged with the lower end of the outer peripheral surface of this outer wall part 9,
A drum body 2 assembled into this compact container 1
By providing the locking piece 11 as a locking means for preventing detachment, the drum body 2 can be firmly attached to the compact container 1 even though it is easy to assemble the drum body 2 to the compact container 1. It can be assembled and maintained.

The locking means as shown in FIG. 5 is similar to the embodiment shown in FIG. In the case of the embodiment shown in FIG. 3, the same structure can be used to successfully implement the invention.

Since the drum body 2 according to the present invention has the above-described configuration, the final outer diameter and height dimensions of the drum body 2 are determined by the main body 3 made of thin metal plate.
This will be determined at the time when the lip body 7 made of synthetic resin is integrally attached and molded.

Therefore, the outer diameter dimension of the outer wall portion 9 of the lip body 7,
By appropriately setting the thickness dimension of the top wall portion 8, it becomes possible to freely mold the drum body 2 of different dimensions from the main body 3 of the same dimension. There is no need to mold multiple types of bodies 3 with slight differences in dimensions, and according to the dimensional relationship, a body 3 of a single dimension can be used as a body 3 for molding drum bodies 2 of different dimensions. You will be able to do so.

Further, since the upper end portion of the cylindrical wall 5 of the main body 3 is covered with the lip member 7, there is no need for any post-processing such as removing burrs from the upper end portion of the cylindrical wall 5 of the main body 3. Therefore, not only the molding of the main body 3 becomes easy, but also the number of man-hours and equipment used for the molding can be reduced.

Furthermore, the dimensions of the drum body 2, that is, the outer diameter and height dimensions, are ultimately determined by the synthetic resin mouth rim 7 that is attached and molded on the main body 3. Since the rim body 7 is molded from an elastic synthetic resin material, even if an error occurs in the molded dimensions, this error can be absorbed by the elastic deformation of the synthetic resin that is the molding material of the rim body 7. , the allowable molding error range of the drum body 2 can be increased to a large value.

Furthermore, the rim body 7 can be molded from a freely selected synthetic resin material without being restricted by the main body 3 and the Koipact container 1, so that the decorative effect of the rim body 7 can be fully exhibited. In particular, the stored cosmetics can be surrounded by a clean color tone, thereby giving a refreshing feeling when using the cosmetics.

In addition, in the case of a structure in which the gap 12 is formed as in the embodiment shown in FIGS. 3 and 5, by providing the locking piece 11 as shown in FIG.
Since the assembly of the drum body 2 to the compact container 1 can be made stronger, and the drum body 2 can be freely attached to and detached from the compact container 1, the drum body 2 is configured in a cartridge structure. can be used in new ways.

As is clear from the above description, the drum body according to the present invention allows an expensive main body made of thin metal sheet to be formed inexpensively and easily. Since the drum body can be molded, the drum body for storing cosmetics can be obtained inexpensively and efficiently without wasting any waste.Also, large dimensional errors in molding are allowed, so there is almost no occurrence of defective products. Somehow, it is firmly attached to the compact container and exhibits many excellent effects such as being able to exhibit a desirable decorative effect.
