Abstract
An improved pressure relief apparatus is disclosed for use with sealed containers such as those found in many galvanic cells. A specially shaped diaphragm (32, 34, 36, 38, 40) is situated across an opening (14) to the interior of the container (10), beneath a piercing point (48). When the pressure within the container reaches a preselected level, the diaphragm snaps rapidly outwardly into contact with the piercing point, thus causing itself to be pierced and relieving the accumulated pressure.
