It is the objects of this invention to keep the middle plate sealed stably and securely in the refill case and thereby to maintain safely the quality of the cosmetic item inside the middle plate with no regard to the sealing of the middle plate and to make the middle plate replaceable at the user's own discretion. <??>A refill case of this invention comprises a middle plate (21) in the shape of a bottomed short cylinder containing a cosmetic item (K) and having outward brim (23) along the periphery of the middle plate (21); a case body (2), which accepts and keeps said middle plate (21) in a storage cylinder (3) under the condition that said brim (23) sits on the top flat rim of this storage cylinder (3); and a cap (9), which is fitted around said case body (2) detachably in screw engagement, and which is used to seal said middle plate (21) through tight contact of said brim (23) with a ring-shaped gasket (16) made of a soft, elastic material, said gasket (16) being embraced by the underside of roof (10) and fitted thereto in an undetachable manner but in a state having play relative to said roof (10), wherein a butting wall (11) is disposed on either one of said case body (2) or said cap (9) so as to butt against the other one at a position in which screw engagement of said cap (9) with the case body (2) is complete and in which soft contact deformation of said gasket (16) is controlled within a range of elastic deformation. <IMAGE> |
