Regarding.

Today, in modern society, with the trend of rapid diversification, people of all ages and genders use cosmetics as needed, but women in particular have a wide variety of cosmetics and a variety of colors. A wide variety of high-quality makeup products and tools are being released one after another through research and development by cosmetics-related companies.

Depending on the purpose of use, the cosmetics include facial cleansing cosmetics used to remove sebum, waste products, and pollutants from the skin surface, and basic cosmetics used to appropriately supply moisture and oil to the skin. Make-up cosmetics used to express beautiful colors, hair cosmetics used to remove foreign substances from the hair or scalp, protect the hair, and supply nutrients to the hair, and fragrances dissolved in alcohol etc. It is classified as a perfume that is used to give off a fragrance to others, and depending on its characteristics, it is made into liquid, gel, solid, or powdered forms and stored in various types of cosmetic containers for use.

For this reason, it has become necessary to develop containers for various types of cosmetics depending on the intended use and characteristics of the cosmetics, but in general, liquid or gel cosmetics are filled into glass containers or tube containers when used. It was first used by the user by picking it up, squeezing it out, and applying it to the skin.

However, such conventional cosmetic containers have problems in that each time a user uses the container, cosmetics get on their hands and they have to wash their hands, which is inconvenient and wastes the cosmetics.

In order to solve this problem, compact containers with built-in makeup tools such as puffs have been developed, eliminating the need to apply cosmetics to hands and making them easier to carry.

Such conventional compact containers are disclosed in Korean Utility Model No. 20-0157472, Korean Utility Model No. 20-0458647, and the like. These conventional compact containers include a cosmetic tray in which cosmetics are stored, a lower case in which the cosmetic tray is stored, an upper case for opening and closing the lower case, and storage in the upper and lower cases. It consists of a cosmetic puff and a cosmetic puff.

However, in the conventional compact container, the cosmetic tray in which cosmetics are stored and the lower case are not separated from each other, so when the cosmetics are used up, only the cosmetic tray must be refilled and used separately. Therefore, the user has no choice but to repurchase the compact container, which not only wastes resources but also imposes a financial burden on the user.

A compact container to solve this problem is disclosed in Korean Patent No. 10-1584512, but this conventional compact container consists of an outer container and an outer container that opens and closes the outer container. The outer container includes a lid, a refillable container holder attached to the inside of the outer container, a refillable container holder lid for opening and closing the refillable container holder, and a refillable container coupled to the refillable container holder. and the refillable container holder are removably connected by undercut, so that when the cosmetic stored in the refillable container is used up, the refillable container holder can be separated from the outer container and replaced with a new refillable container. can be combined.

However, in order to separate and replace the refillable container in which cosmetics are stored from the outer container, this conventional compact container has to push up the bottom of the refillable container exposed to the outside and remove the refillable container and the refillable container holder. Since the refill container is forcibly separated from the outer container, there is a problem in that it is difficult for women who are relatively weak to separate the refill container from the outer container. In addition, if the refillable container is pushed excessively by hand, the bottom of the refillable container may be crushed and damaged, or the refillable container may suddenly pop out from the outer container, causing inconvenience in terms of replacement and use. There was a point.

Therefore, there is a need for the development of a cosmetic container that allows the user to easily separate and replace the refillable container from the outer container with simple operations.
