Galvanic cell having a resealable vent closure

摘要

A resealable vent closure for an electrochemical cell comprising a disk seal having a first upstanding wall to define an opening to accommodate a current collector rod of a cell and having vent grooves disposed in the first wall, and having a second upstanding peripheral wall with vent channels and said second wall being crimped between a cover for the cell and the top edge of a container containing the active components of the cell to thereby produce a sealed cell that is resealable.
