Abstract
A closure membrane is described for closing a can opening which membrane comprises a flat part and a peripherally adjoining border zone destined to be hermetically sealingly connected to the can. In order to remove the flat part of the membrane safely and completely an opening is provided in the flat part of the membrane. This opening in the membrane is hermetically sealed by a piece of foil attached to the underside of the membrane and forming a tab element the bent back end of which projects out of the opening and forms the tab proper.
