ABSTRACT:
A battery container, the walls of which, include integrally molded, resilient ribs extending at acute angles from the walls to retain the battery's electrochemical innards firmly in the container. Each as-molded rib is plastically deformed and reshaped so that a lead-in portion thereof near the container opening is at a lesser angle with respect to the wall than the undeformed portion of the rib which serves to resiliently retain the innards. The section of rib between the lead-in portion and retaining portion extends at various angles intermediate the other angles and provide an incline or ramp for facilitating insertion of the battery's innards into the container. The tooling used to plastically deform the lead-in portion of the rib may also include means for tearing the bottom of the rib away from the bottom of the container.
