Abstract
The present invention relates to a compact container provided with an airtight packing having upper and lower sealing rubbers, and a coupling tension protrusion, in which the airtight packing is coupled on top of a refill container, wherein the upper sealing rubber is brought into close contact with a refill container cover and the lower sealing rubber is brought into close contact with the refill container, so as to render airtight a cosmetic material accommodating space, thereby preventing cosmetic material from evaporating or becoming volatile to allow the cosmetic material to function properly for a long time. Also, the cosmetic material accommodation space in the refill container is maximized by removing an existing middle container and directly coupling the refill container to a container main body, thereby enabling effective filling of more cosmetic material to minimize frequent refilling of the cosmetic material.
