(US4457990-A)      Galvanic cell comprises a sealing gasket compressed between its cover and outer container. The gasket has a horizontal base with an inner flange and an outer flange. The outer flange is compressed between the inner wall of the container and the edge of the cover to form a seal and insulate the cover from the container. The inner flange and base of the container define or chamber which contains the cell cathode and separator. The upper portion of the inner flange is turned inwardly and compressed on top of the outer edge of the separator to define a cavity in which the cell anode is positioned between the separator and cover.    USE/ADVANTAGE -   Thin miniature cells. Internal shorting is prevented by isolating the cathode from the anode and cell cover.    (6pp)o    (EP89496-B)      Galvanic cell comprising a container (2) having a base (4), a sidewall (6) and an open end and housing a cathode material (20) in electrical contact with said cell container (2), an anode material (28), a separator (22,24) between said anode (28) and said cathode (20), an electrolyte (30) in ionic contact with said cathode material (20) and said anode material (28), a cell cover (32) disposed over the open end of the container (2) and in electrical contact with said anode material (28), and a sealing gasket (10) of said resilient material compressed between said cover (32) and said container (2), wherein said sealing gasket (10) comprises a horizontal base (12) having an inner flange (16) and an outer flange (14); said flanges, including the upper portion (26) of the inner flange (16), being upstanding in the uncompressed state, said outer flange (14) being disposed adjacent to the inner sidewall (6) of the container (2) and compressed between the container sidewall (6) and the edge (34) of the cover (32) thereby electronically insulating said cover (32) from said container (2) and sealing said cover (32) to said container (2); said inner flange (16) and the base (4) of the container (2) defining a compartment which contains the cathode (20) and the separator (22,24) thereon and wherein said upper portion (26) of the inner flange (16) of the gasket (10) is turned over and compressed on top of the outer edge of the separator (22,24) thereby effectively isolating the cathode (20) from making electronic contact with the anode (28) and cover (32) of the cell.
