Abstract
A housing for a button cell battery includes a top, a can and a grommet. The skirt of the can extends between a top panel and a free end, and includes a substantially vertical first section and an outwardly tapered second section. The first section extends from the top panel of the can. The second section extends from the first section. Upon assembly of the housing, a flow path is defined between an outer surface of the skirt of the grommet and the inner surface of the skirt of the can. The flow path allows air to escape during the assembly, thus minimizing the risk of gas being entrapped within the interior of the housing of the finished cell battery.
