Abstract: A container and a method for making the same for a gas generating propellant such as used in vehicle air bag systems. The container comprises an elongated thin wall metal cylinder having a plurality of perforations extending substantially the length thereof. A hermetic liner is attached to the inner surface of the cylinder to seal the perforated area of the wall. The hermetic liner comprises a laminated plastic film and metal foil composite having a thickness less than that of the cylinder wall and being rupturable under the pressure of gas generated within the cylinder. The ends of the cylinder are closed by metal end caps.

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.
