Latest Patents

Sakamoto holds a patent for a dry cell and the method of manufacturing its outer metal jacket. The patent describes a unique process where notches are formed at the corners of only one side edge of a metal jacket blank made from a rectangular metal strip. This blank is rolled into a cylindrical shape, creating an abutment joint. The lower end of the blank is inwardly curled and crimped to form a bottom, completing the outer metal jacket. After loading a cell member into the jacket, the upper end is also inwardly curled and crimped, allowing the notches to abut the other side edge. This design prevents dents caused by buckling during crimping and facilitates more efficient production of dry cells.
