description An end seal assembly for small sized cylindrical alkaline cells. The seal assembly eliminates the need for a separate end cap and also eliminates the need for an insulating washer which is normally included between the end cap and housing at the cell's open end in order to insulate the end cap from the housing. The seal assembly includes an insulating sealing disk which fits into the open end of the cell housing. The peripheral edge of the cell housing is crimped over the edge of the sealing disk to seal the cell. The sealing disk comprises an integral raised central boss which protrudes from the housing open end. An elongated current collector penetrates into the cell's interior through an aperture in the central boss. The head of the current collector is thus exposed to the external environment and forms an end (negative) terminal for the cell. The boss is wider than normal in order to prevent interlocking with heads from other like cells.
