ABSTRACT:
An end cap for a tubular container having a deep drawn flanged cup adapted to receive an igniter device for igniting the explosive contents of the container, such as the propellant for generating gas for expanding an air bag in a vehicle passenger restraint system. The cup has in its bottom wall, a centrally located aperture normally sealed by a composite laminate of plastic film and metal foil that is rupturable by the signal from the igniter device. A plastic annulus interposed between the igniter device and laminate protects the latter against frictional erosion by rubbing action of the igniter device through environmental vibrations transmitted to the propellant container.
