GALVANIC DRY CELL WITH HIGH PRESSURE SAFETY VENT

摘要

Radially sealed galvanic dry cells having a safety high pressure vent means comprising the crimping of an arc portion between about 150 DEG and 190 DEG of the top edge of the container over the cell closure means so that after a predetermined high internal gas pressure build up, the gas will tip the closure means and produce a vent passage between the cell's container and closure means proximal the remaining arc portion of the top edge of the container.
