Title: Refillable cosmetic container

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the priority of Korean Patent Application No. 10-2021-0005331 filed on Jan. 14, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. 
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present disclosure relates to a cosmetic container, and more particularly, to a refillable cosmetic container capable of being easily refilled and installed and separating a film conveniently. 
     Description of the Related Art 
     In general, as a method of using liquid cosmetic contents such as cosmetics, which preferably use a small amount of eye cream and the like at a time, but use a precise quantity, in the related art, a method of individually packaging the contents in the form of a capsule or the like by an amount to be used for each use time was used. 
     However, such an individual packaging method has a problem in that it is inefficient because a relatively large amount thereof remains in the capsule even after a user uses the cosmetic contents. 
     In order to overcome the problems of such an individual packaging method, after the contents are received in a container, there is disclosed a configuration of extracting the cosmetic contents every use by using an extracting means having a general pipette or syringe structure or using an extracting means having a configuration of a push pump. 
     Meanwhile, when the cosmetic contents are extracted by using the extracting means of a conventional syringe structure, it is inconvenient because an area coupled with the piston is exposed to the outside of the container and it is unsanitary because foreign substances may be stained on the exposed area, so that the improvement thereof is required. 
     In particular, when the pressing force is applied by the user to automatically pump the cosmetic contents, the convenience of use may be improved, and therefore, measures for improvement are also required. 
     The above-described technical configuration is the background art for helping in the understanding of the present disclosure, and does not mean a conventional technology widely known in the art to which the present disclosure pertains.
