Patent number: 6402794Abstract: 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.Type: GrantFiled: November 19, 2001Date of Patent: June 11, 2002Assignee: Eveready Battery Company, Inc.Inventor: Manuel R.
