发明名称 Metal can with membrane type closure
摘要 A metal can with a membrane covering the opening in the can is sealed to a circumferential flange which is part of a necked-down region on the can body. The necked-down region can be provided directly at the edge of the opening end of the can body and the flange can be in the form of an end flange. It may, however, also be provided at such a distance from the edge of the can body at the opening end of the can, that a cylindrical extension results beyond the flange. By forming the flange directly on the can body, the can, which is able to be used widely, can be made simply and in a manner which saves material.
