LUKKEANORDNING TIL GALVANISKE ELEMENTER, SAMT FREMGANGSMAADE TIL FREMSTILLING AF SAMME

摘要

A closure for a galvanic element, and particularly a cylindrical cell, is formed in substance of a cap-like or toroidal, resilient member, whose upstanding outer rim is segmented by slits into distinct flaps. These are therefore capable of acting resiliently in a radial direction and are capable of maintaining in the sealing region a steady sealing pressure between the cup and a plastic closure member. During closing of the cell through crimping, the flaps are supported from inside by a crimper support sleeve. In this way, the plastic of the closure body is plasticized during movement of the crimping tool toward the die.
