Claims15
An electrochemical cell comprising a pressurized container having a cylindrical can body with a cylindrical side wall, a closed bottom end and an open upper end, the upper open end of said can body being curled to the shape of a torus, the innermost portion of which has a diameter not greater than the diameter of said can body;
- a closure for said container, said closure comprising a metallic element having a curved lip crimped against said torus;
- means to insulate said can body from said cover;
- an anode, a cathode and an electrolyte operatively positioned within said container, one of said anode or cathode being electrically connected to said can body and the other being electrically connected to said cover.
An electrical device comprising an electrical body in a cylindrical container, said container having an open end defined by a rim, the rim of the container being rolled over inwardly toward the axis of the container, and a closure assembly including a member having its periphery crimped against the rolled over rim to generally conform its shape to the shape of a portion of the rolled over rim of the container and to seal the container.
