Description

[Detailed description of the invention] << Industrial application field >> The present invention relates to a compact container. More specifically, the container body and the lid are connected to each other so as to be openable and closable at the rear portions thereof, and are inserted into the container body. A compact body in which a cosmetic storage section is formed, an elastic member is disposed between the container body and the lid, and when the lid is closed, the elastic member presses against the opening of the cosmetic storage section and is kept airtight. For containers.

<< Conventional technology >> In a conventional compact container of this type, an elastic packing is disposed on the inner surface of a lid, and the packing is pressed against the outer peripheral upper surface of the cosmetic storage section by closing the lid, thereby forming a cosmetic. Generally, the storage section is hermetically sealed.

However, in this type of compact container, when the packing or the container body is slightly deformed such as warpage, normal close contact is not performed, and it is difficult to stably maintain airtightness.

To solve such a problem, Japanese Utility Model Application
The compact container as shown in the gazette is devised. In this compact container, a packing is formed on the inner surface of the lid, and an annular fitting wall is formed protrudingly on the container body side of the packing, and this fitting wall is formed on the inner periphery of the opening of the cosmetic storage portion of the container body. Airtightness is maintained by inserting and fitting to the surface, so that even when deformation or the like occurs in the packing or the container body, airtightness can be stably maintained.

<< Problems to be Solved by the Invention >> However, the following problems occur in the compact container as disclosed in Japanese Utility Model Laid-Open No. 60-116907. That is, when closing the lid, the lid rotates around the hinge as a fulcrum, and the fitting wall of the packing fixed to the lid is not fitted into the opening of the cosmetic storage section from the vertical direction. The rear end of the fitting wall comes into oblique contact with the upper edge corner of the rear end of the opening of the cosmetic container. In other words, the distance connecting the center of the hinge and the tip of the rear end of the fitting wall of the packing is shorter than the distance connecting the center of the hinge and the upper edge corner of the rear end of the opening of the cosmetic storage unit. To close the fitting wall of the packing into the cosmetic storage part, a relatively strong force is required, thereby forcibly deforming the fitting wall of the packing and overcoming the upper edge corner of the opening. You have to push it.
In addition, when the lid is opened, similarly, a relatively strong force is required when the fitting wall of the packing separates from the opening of the cosmetic storage unit. There was a point.

Furthermore, in the above-mentioned compact container, since the packing fitting wall is forcibly fitted, the fitting wall of the packing may be damaged or partially deformed, which may lead to poor airtightness of the compact container. was there.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a compact container that can keep cosmetics airtight and can smoothly open and close a lid.

<< Means for Solving the Problems >> In order to achieve the above object, in the present invention, the diameter of the cosmetic storage section is increased stepwise along the periphery of the opening,
An annular enlarged step section defined by an inner peripheral surface and a shelf surface, and a distal end edge extending from a peripheral edge of the elastic member has a dimensional shape of the step inner peripheral surface toward the enlarged diameter step section. An annular flexible bulging portion formed in a shape of an arch having a shape substantially equal to or smaller than that of the flexible bulging portion; A deformation restricting portion for expanding and deforming the flexible bulging portion, which is in contact with the leading edge and pressed against the step shelf surface, toward the inner peripheral surface of the step portion.

<< Operation >> When the lid is opened, the flexible bulging portion of the elastic member fixed to the lid is curved into a shape that can be inserted into the opening of the cosmetic storage portion of the container body.

When the lid is closed from this state, the elastic member is inserted into the cosmetic accommodating portion, whereby the flexible bulging portion is pressed against the step shelf surface of the enlarged diameter step portion, and the flexible bulging portion is The flexible bulging portion is further expanded and deformed toward the inner peripheral surface of the step portion by the deformation restricting portion with which the leading edge abuts, and is brought into close contact with the inner peripheral surface of the step portion. The deformation mode of the flexible bulging portion after being pressed against the shelf surface is determined by the deformation restricting portion in a direction expanding toward the inner peripheral surface of the step portion. It is surely kept airtight.
