Description

[Detailed explanation of the invention] (Industrial application field) This invention is related to compactness.
In particular, the present invention relates to a device for fitting a powder tray into a compact body.

(Prior Art) Conventional compacts, for example those molded by plastic injection molding, are provided with a separate white powder tray that approximately matches the inner surface of the main body, and this is mounted inside the main body. . In addition, when it comes to high-quality metal products, a cosmetic storage recess is provided inside the inner frame that is fitted to the inside of the main body so that it does not fall out, and for white powder dishes that do not fit into the recess, there is a compatible container called an adapter. I used my body. This has an inner side approximately matched to the outer diameter of the powder tray that is desired to be stored, and an outer circumferential side that is sized to prevent accidental falling inside the cosmetic storage recess of the inner frame.
Several types of adapters like this were prepared so that several types of white powder dishes could be used. In addition, with a slightly more advanced idea, a recess is provided on the circumferential side of the inner lower part of the main body that stores cosmetics or the middle frame, and the expandable and retractable conformable body is fitted into the concave part and inserted into the conformable body. It was possible to press-fit various types of white flour trays onto the inner circumferential surface thus formed.

(Problem that the invention aims to solve) When using such a compact, it is only possible to use a white flour tray that fits the storage compartment, and if a white flour tray of a different shape is used, the gap may be It was not very beautiful and unhygienic as white powder spilled into the gaps. In addition, if an adapter is used, extra parts must be prepared, and the price will be higher.Also, the use of "an appropriate extendable and contractible body" mentioned at the end of the (prior art) column. is a coiled spring made into a ring, but compared to conventional compact adapters, it has a different form and price (with current technology, to make a coil with a polygonal cross-sectional shape, each corner needs to be Since the coil is bent and rolled one turn at a time, it takes about five minutes to make the required length, making it a very expensive process. is slightly inferior in terms of flexibility (this is necessary and indispensable in order to adhere tightly to the side circumference of the white powder dish without any gaps), but it is superior in terms of flexibility.
Furthermore, in the former case, a sticky gel-like substance was applied to the back of the white powder dish to fix it to the compact body, but in the latter case, the area around the white powder dish was lightly pressed, so the gel-like substance was not used. You don't have to. The comparison between the two is as above, but the negative effects of the latter form and price are extremely large in terms of commercial policy.
Technical problems arise in order to obtain a stretchable and conformable body that is cost-effective.

(Means for solving the problem) In order to achieve this purpose, this invention has the following configuration. In other words, the compact according to this invention is a coiled spring made into a ring, and instead of determining the required shape, thin pieces are formed into the required cross-sectional shape, and then stacked to the required length to form a rod shape. Then, the rod-shaped body is bent into a circular shape, and a coiled spring is formed into a ring so as to bias it from the outside to the inside. (This can be done at a very low cost), or by pressing with a ring-shaped elastic body such as a rubber band, and fitting a white powder tray into the inner circumferential surface formed by the piece.

(Function) When pressed from the outside, the stacked pieces expand and contract in the same way as a ring of coiled springs, and apply pressure evenly around the large and small white flour trays with the inner end surfaces of the pieces. , to prevent the white flour tray from being accidentally removed.

(Example) An example of this invention will be described in detail with reference to the attached drawings.

1 and 1' are piece bodies, and metal pieces having notches 11 or holes 11' cut out or penetrated as shown in FIGS. 3 and 4 are arranged in a ring shape as shown in FIG.
A ring 2 made of a coiled spring is elastically fitted into the notch 11 from the outside. As shown in FIG. A white powder tray is press-fitted onto the inner circumferential surface formed as a result.

(Effect of idea) This idea produced the following effects.

1. Since a single piece can be punched out to process many pieces at once, it is easy to reduce the price even if a large number of pieces are used. Also, a coiled spring for focusing internal pressure in a ring is easy to manufacture. , since the cheapest and most efficient processing method can be used, the price can be extremely low, and the price of the compatible body will therefore drop significantly.

2. Since it is stretchable, several types of white powder can be used.

3. Since the white powder dish is pressurized evenly around the circumference, there is no need to apply a sticky substance to the back of the white powder dish, and therefore, there is no need to stain your fingers with mucus when replacing the white powder dish.
