Abstract
Pressure release means for pressurized containers and particularly electrochemical cell containers subject to pressure eruption conditions in which the pressure release means is an integral part of the container wall. This means is actuated at predetermined abnormal pressure at which a relatively rigid and undeformed wall area between two deformed portions of the container wall tears to form a vent. This vent can be adapted to provide either slow or rapid pressure release.
