Indented electrode cup for a miniature galvanic cell

A galvanic cell comprising:

• a) a first electrode having a polarity;
• b) a second electrode of opposite polarity;
• c) a separator between said first electrode and said second electrode;
• d) an electrolyte;
• e) a two-part conductive housing containing said first electrode, said second electrode, said separator and said electrolyte, the first part of said housing being a can electrically connected to said first electrode and having a wall and an edge defining an opening, and the second part of said housing being a cup electrically connected to said second electrode, having an upstanding wall with an outer surface and an edge end defining an opening, and having an inward indented area at the vicinity of the open end of the cup;
• and
• f) an insulating gasket comprising a base member having a bottom surface contacting said first electrode, an outer wall having a top edge, and an inner wall spaced apart from the outer wall thereby defining a "U" shaped groove;
• wherein the edge of the cup's wall is disposed within the groove of said gasket, the outer wall of said gasket is disposed between the wall of the can and the wall of the cup, the outer wall of said gasket has a height sufficient so that the top edge of said gasket's outer wall is disposed on the outer surface of the cup's wall at the indented area, and the edge of the can's wall is secured against said gasket thereby sealing the can to the cup at the indented area of the cup via said gasket.
