The airtight cosmetic container of the present invention can be kept being airtight without using extra rubber packing (airtight packing) between an inner container (200) and an inner cover (300); the inner container can be kept being airtight by correcting enough the outer diameter difference due to molding errors of the inner cover; deformation is prevented even in a long term use; a discharge of air is provided for sealing the inner cover when opening and closing the outer cover, which keeps the airtight properties completely; furthermore, the reliability of the product can be secured. The cosmetic is filled in the inner container (200); a sealing rib (320) protruding from the lower part is inserted into a packing groove (221 ) of a packing case (220) of the inner case by closing the inner cover; at the same time, inner and outer curvature protrusion parts (222a, 223a) seal, elastically, the inner and outer sides of the sealing rib. The sealing rib is combined to the packing groove. The inner and outer curvature protrusion parts are protruding from the inside of inner and outer elastic pieces (222, 223) forming the packing groove. |
