Disclosed herein is a compact type of airtight cosmetic container. A shoulder cap (40) to which a mesh is coupled and a puff storage cap (50) which stores a puff are successively placed onto and coupled to a medial body (30) which contains a cosmetic therein. The shoulder cap and the puff storage cap can be airtightly coupled to the medial body by a sealing member (51) provided under the puff storage cap and a sealing ring (43) provided in the lower surface of the shoulder cap. A pressurizing means pressurizes the puff storage cap onto the medial body such that the sealing member and the sealing ring are compressed, whereby the sealability of the cosmetic container can be enhanced so that leakage of powder or a cosmetic change attributable to water evaporation can be reliably prevented.
