Sealing mechanism for a cylindrical container opening using a cap having a cap body and an upper lid
Patent number: 8757410Abstract: A sealing mechanism for a container opening having a cylindrical opening disposed on a container body and a cap for sealing the cylindrical opening. The cap includes a screw-on cap body and an upper lid for sealing the cylindrical opening.
