ABSTRACT:
A sealed galvanic dry cell that has a sealing means comprising a terminal cover having a peripheral extending flange that is compressed between a neutral cover and a rim of the open end of a cell's container by use of a compressable gasket that operates such that the rim of the container further interlocks with the flange of the terminal cover upon the buildup of internal pressure to effectively maintain the seal for the cell.
