Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an airtight cosmetic container useful for preventing drying and solidification of volatile cosmetics.

BACKGROUND TECHNOLOGY Conventionally, this type of container has a cap body or a stopper made of rubber or resin installed inside the cap, and when the cap is attached, the cap or stopper closes the opening of the container body, thereby preventing outside air from entering the container. Structures that block intrusion are known. However, with conventional containers, no consideration has been given to the discharge of the air inside the cap, that is, where the air can escape.Therefore, when the cap is closed, there is strong resistance due to the internal air pressure, making it troublesome to attach the cap, and also temporarily Even when the cap is properly closed, the repulsion of air pressure causes the cap to float, making it extremely difficult to ensure sufficient airtightness within the container.

Problems to be solved by the invention This invention improves the conventional container by adding an air exhaust function to the cap body, and automatically eliminates the air inside the cap body when the cap is attached to prevent the cap from floating. At the same time, it is intended to block the intrusion of outside air and ensure complete airtightness inside the container.
