Abstract

A compact case having an airtight structure, refillable with a capsule cosmetic includes: a lower case having a hole and an elastic locking member on a bottom; an upper case connected to the lower case by a first hinge pin to be opened and closed; a capsule cosmetic for refilling including a capsule and a liquid cosmetic material impregnated in a porous pad within a capsule, sealed with a sealing member removed upon the first makeup application, and fitted in the hole of the lower case with a bottom of the capsule exposed to the outside and a locking groove on the capsule elastically detachably locked to the locking pins; an internal container having an inner wall and an outer wall for forming a fitting groove and disposed outside the capsule cosmetic; and a lid connected to the internal case by a second hinge pin to be opened and closed, having a puff seat on a to and a fitting rib, which is fitted in the fitting move of the internal container, on a bottom, in which the capsule cosmetic and the lid are sealed by being elastically in close contact with sealing projections, respectively, on the inner wall and the outer wall of the internal container. Therefore, it is very simple to replace a capsule cosmetic in the lower case for refilling and the cosmetic material is not vaporized by the sealing structure, so it is possible to use the cosmetic, maintaining the quality of the cosmetic for a long period of time.
