Ready-to-install sealing unit for a container, a method for mounting a sealing unit on a container body and a container

摘要

A sealing unit for sheet-metal containers which is composed of a reusable lid (10) and a diaphragm (11) and is integrally mounted on a can body (9) and is simultaneously connected and/or welded to the body (9). The welding pressure is generated and maintained by the lid (10) directly. The heating of the contact surface between the diaphragm (11) and the body (9) may take place before or after the diaphragm (11) is mounted on the lid (10). <IMAGE>
