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.
