In other words, when the lid is closed, the lid rotates about the hinge as a fulcrum, so that the fitting wall of the packing fixed to the lid is not vertically inserted into the opening of the decorative plate. The rear end of the mating wall comes into contact with the upper edge corner portion of the rear end portion of the opening of the decorative plate at an angle. In other words, the distance between the hinge center and the rear end of the fitting wall of the packing is shorter than the distance between the hinge center and the upper edge corner of the rear edge of the opening of the decorative plate, so further close the lid from this state. A relatively strong force is required to fit the fitting wall of the packing into the decorative plate, which causes the packing wall of the packing to be deformed forcibly to overcome the upper edge corner of the opening and to be pushed in. It becomes indispensable. Similarly, when the lid is opened, a relatively strong force is required when the fitting wall of the packing moves away from the opening of the decorative plate, which causes a problem of discomfort during the opening / closing operation. there were.

Further, in the above-mentioned compact container, the fitting wall of the packing is forcibly fitted, so that there is a problem that the fitting wall of the packing is scratched or partially deformed, resulting in poor airtightness of the compact container. I was afraid. Further, there is a problem that the length and material of the fitting wall of the packing are also restricted.

The present invention has been made in view of the above problems, and an object thereof is to provide a compact container capable of holding cosmetics in an airtight manner and smoothly opening and closing them.

<Means for Solving the Problems> In order to achieve the above object, in the present invention, a container body and a lid are pivotally attached at their rear portions so as to be openable and closable, and a recess for accommodating cosmetics is provided in the container body. And a packing is disposed between the container body and the lid, an annular protrusion is provided on the lower surface of the packing, and when the lid is closed, the annular protrusion causes the opening of the recess. In a compact container adapted to be airtightly retained by fitting to the inside of the lid, the packing is slidably mounted on the inner surface of the lid, and when the lid is opened and closed, the annular projection of the packing is located in the recess. When the upper edge corner portion is abutted, the packing slides back and forth, and when the lid is locked, the annular protrusion fits in the recess to keep the recess airtight. It has a simple structure.
