Description

[Detailed description of the invention] This invention has excellent airtightness, and maintains the quality of cosmetics in good condition for a long period of time without letting the moisture or volatile substances of the cosmetics stored inside the container escape. More specifically, in a compact in which the body and the lid are connected by a hinge so that they can be opened and closed, a convex ring is provided on the upper surface of the periphery of the cosmetic storage recess in the body, An inner frame having an inner diameter larger than the outer diameter of the convex ring and having an outer diameter that can be fitted into the lid is interposed between the body and the lid via a hinge, and further attached to the inner frame. This invention relates to an airtight compact characterized by being stretched with a film.

Conventional compacts generally have poor airtightness, which has the disadvantage that moisture or volatile content of the cosmetic impregnated substance stored inside the compact evaporates outside the container, deteriorating the quality of the cosmetic.

The compact according to the present invention relates to a completely new technology developed in view of the drawbacks of the conventional technology.

To specifically explain one embodiment of the compact according to the present invention with reference to figures, in Figs. 1 to 3,
1 has a recess 2 in which cosmetics can be stored, and a convex ring 3 is provided in an upright manner on the upper surface of the peripheral edge of the recess 2. Reference numeral 4 denotes a lid, which is pivoted to the body 1 via a hinge 5 so as to be openable and closable. Reference numeral 6 denotes a middle frame, which has an inner diameter larger than the inner diameter of the convex ring 3 and an outer diameter that can fit into the ceiling of the lid 4, and is connected to the body 1 and the lid by the hinge 5. 4, and is pivoted so that it can be opened and closed. Further, a synthetic resin film 7 is stretched over the entire back surface of the middle frame 6. 8 in the figure,
Reference numeral 9 designates engaging hooks provided at the openings of the body 1 and the lid 4.

In the compact according to the present invention, a convex ring is provided on the upper surface of the peripheral edge of the body, and an inner frame having an inner diameter larger than the convex ring is interposed between the body and the lid so as to be openable and closable. Since the film is stretched over the inner frame, when the compact is closed, the film in the inner frame will come into close contact with the convex ring, thereby completely sealing the concave part of the body, keeping the concave area airtight. It is possible to completely prevent the moisture or volatile substances of the cosmetics stored in the recess from evaporating, and therefore the quality of the cosmetics can be maintained well for a long period of time.
