Dual type cosmetic container and its manufacturing method

The present invention relates to a dual cosmetic container and a method for manufacturing the same, and more particularly, to a dual cosmetic container and a method for manufacturing the same to be able to selectively use a variety of different cosmetic liquids and applicators.

In general, in case of makeup by brushing liquid cosmetics such as lip balm, lip gloss, mascara, eyeliner, and nail polish, the cap and the hair bundle are mainly formed by screwing the cap of the brush with the hair bundle on the cosmetic container. It is designed to be easily carried in the state of being stored inside the container, and if necessary, the cap can be removed and the makeup can be applied with a brush soaked with a makeup solution.

According to the cosmetic method, two or more kinds of cosmetics are used together sequentially. In the case of eye makeup, after mascara, it is common to use an eye line, and in the case of lip makeup, it is common to apply a coating liquid after lip makeup. In the case of nail cosmetics, it is common to apply a coating solution after manicure.

In order to make up these cosmetics, each cosmetic product must be purchased and stored separately, which leads to a narrow and complicated cosmetic storage space, and incurs a cost burden for purchasing cosmetics. This hassle has often led to avoiding makeup during the unconsciousness or to finishing makeup with the intermediate process omitted.
