Abstract
An apparatus for inflating an air bag includes a container (12) which holds a supply of gas under pressure. The container (12) is filled with gas through an internally threaded opening (48). Once the container (12) has been filled with gas, an externally threaded plug (50) is threaded into the internally threaded opening (48) in the container. A seal ring (60) extends around the plug (50) and provides a first seal between the container and the plug. A weld (64), which extends around a peripheral portion of the plug (50) and extends between the plug and the container, provides a second seal between the container and plug.
