Storage container

Abstract

To prevent a sealing member from falling off, facilitate attachment of the sealing member, and improve the sealing property of the sealing member. The sealing member of the present invention includes a plurality of individually deformable portions fitted into fitting groove portions separated across a protrusion in the fitting groove formed in one of a container main body and a cover member, a coupling portion connecting the individually deformable portions, and a sealing piece abutting against a wall surface of the other one of the container main body and the cover member to seal a space, the sealing piece being integrated with the coupling portion connecting the individually deformable portions. Convex ribs are respectively formed on opposite sides of the individually deformable portions to elastically come into close contact with the wall surface of the protrusion.
