Description

Refillable cosmetic container

The present invention relates to a refillable cosmetic container, and more particularly, a refillable inner container filled with cosmetic contents is detachably inserted into the outer container, and the inner container is replaced with a new one when the cosmetic contents are exhausted. However, the inner container can be locked by turning the container support clockwise at a certain angle, for example, 90°, and after using the contents, turn the container support counterclockwise to turn the inner container After switching to unlocking state, it can be easily separated from the outer container, discarding only the inner container with a simple structure, and combining the new inner container with the outer container. It relates to a refillable cosmetic container that can reduce environmental pollution and save resources.

In general, a cosmetic container is composed of a cosmetic container having a liquid or gel-like cosmetic material therein, and a lid detachably coupled to open and close the entrance of the container.

Accordingly, when all of the cosmetic materials contained in the cosmetic container are exhausted due to repeated use of the cosmetic material, the consumer discards the entire cosmetic container and purchases and uses a new cosmetic container.

However, conventional cosmetic containers are mostly produced and sold only for one-time use even when the cosmetic contents are the same, thus burdening consumers with cosmetic container manufacturing costs. There is a serious problem.

In order to solve this problem, as shown in Korean Patent Registration Publication No. 10-1211964, a cosmetic container for refilling provided to replace only the cosmetic container with the cosmetic contents (material) has been developed, but the overall configuration is too complicated.
