Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
In an electric storage battery having a container, a cell element in said container, a post extending from said element through a wall of said container, a terminal outside said container having a root engaging said element post and a connector post extending from said root for engaging a battery terminal connector, and a shipping and display cap for shielding said terminal against damage and protecting said battery from accidental discharge, the improvement wherein said cap comprises: a base permanently encasing said root while said battery is in service; means operatively associated with said base for anchoring said base about said root; and a tower separable from said base and encasing said connector post, said tower being joined to said base along a perforated parting line including a plurality of frangible links defining a plurality of perforations therebetween for facilitating ready separation and removal of said tower from said base to expose said connector post to receive said connector.
