Abstract
The leakage of electrolyte from alkaline primary batteries is substantially reduced by improving the seal in such batteries. The novel seal is formed by applying a hard, tackless conductive alkali-resistant plastic coating to the surface of the metal container which forms a bond between the metal container and the sealant covered seal member normally used in such batteries.
