Battery construction having cover assembly
First Claim
1. A battery comprising:
- a container for containing battery materials including positive and negative electrodes, said container having a first end, an open second end, and side walls extending between said first and second ends;
an outer cover positioned across the open second end of said container, said outer cover having an outer peripheral flange and an inner flange and a channel formed between the outer peripheral flange and the inner flange, wherein the channel receives the open end of the container such that the outer flange and inner flange are on opposite sides of the side walls of the container; and
a seal disposed between the outer cover and the container, wherein said seal is compressed between the inner flange and the container and is compressed between the outer flange and the container.

Abstract
A battery comprising a steel can having a bottom end, an open top end, and side walls extending between the top and bottom ends. Positive and negative electrodes are disposed in the can. An outer cover is disposed over the open end of the can. The outer cover has an outer flange disposed on the outside of the can walls and an inner flange disposed on the inside of the can wall. A seal is disposed between the can and the outer cover so that the seal is disposed against the inner and outer flanges of the outer cover. The outer cover is preferably crimped against the can wall to compress the seal between the inner and outer flanges and the container, thereby minimizing axial loading on the can and allowing for use of a thin gauge can.
