ABSTRACT:
A sealing and insulating member for a cell formed with an inwardly directed shoulder in the periphery of the member. A downwardly and outwardly extending skirt extends below the shoulder, the maximum diameter of which is located at its lowest extremity with that diameter being greater than the diameter at the bead of a cell can. The sealing and insulating member can be snap-fitted into the can prior to crimping, and held in place without the necessity to pre-crimp.
