Abstract
A container subject to damage through inadvertent overheating and pressure build up such as a rocket casing containing a propellant which can be subjected to damage or inadvertent firing when the ignition temperature is achieved inadvertently includes a thermally actuated release mechanism. The rocket casing includes two sections which are mechanically latched. A thermally responsive material such as Nitinol is provided in a shape such that upon being subjected to a predetermined transition temperature lower than the ignition temperature of the rocket propellant, it changes shape so as to mechanically unlatch the rocket casing sections.
