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 200 DEG of the top edge of the container over the cell's gasket-cover closure means so that at a predetermined high internal gas pressure build up, the gas will tip the cover of the closure means and produce a vent passage within the cell housing between the cover and the gasket of the closure means proximal the remaining arc portion of the top edge of the container.
