<p>A cell cap including a base, a top, a connector, one or more wings between the base and the top, and a lock. The top may engage the base and be moveable relative to the base. The connector may be moveable relative to only one of the base and the top. Each wing may have a first portion engaging the connector and a second portion engaging the cell. When pressure within the cell exceeds pressure outside the cell, the lock may lie in a first position, preventing relative movement between the base and the top. When pressure within the cell does not exceed pressure outside the cell, the lock may lie in a second position, allowing relative movement between the base and the top to cause the connector to move the first portion of the wing, thereby causing the second portion of the wing to move.</p> |
