PROCESS FOR ULTRASONIC SEALING AN ANODE CUP INTO A GASKET FOR ELECTROCHEMICAL CELLS

摘要

A gasket-cover assembly for use as a closure for an electrochemical cell which is produced by a process in which an extended wall (16) of the cover (8) is ultrasonically forced into a flange (6) of a gasket (4) such that the flange of the gasket makes a "U" shaped enclosure about the bottom wall of the cover.
