Abstract:
A closing mechanism for a container opening, comprising:a support body bent at a predetermined curvature; a lid body; a hinge closably joining said lid body and said support body at end portions thereof; one of said support body and said lid body having a socket penetrating in a thickness direction thereof at an end portion thereof and the other of said support body and said lid body having a hook at an end portion thereof that can be fitted to said socket to close and join said lid body to said support body; an elastic material capable of closely contacting with said support body, said elastic material having a restoring force; and a closable passage body formed from a soft sheet having opposite sides interposed between said support body and said elastic material; wherein said passage body and said elastic material are interposed between said support body and said lid body; wherein said elastic body is pressed by said lid body so as to be bent at a predetermined curvature along said support body; and wherein said passage body is normally closed, but said elastic material is deformed to allow said passage body to open when a rod-shaped body is inserted into said passage body between said support body and said elastic material, and said elastic material is caused by the restoring force thereof to come into close contact with said support body and to close said passage body when the rod-shaped body is pulled out of said passage body.
