Patent ID: 7461860

Claim:
A combustible gas inflator, comprising: an enclosure configured to receive and store the combustible gas under pressure, the enclosure having an outer wall comprising an exterior surface, an interior surface, and a fill aperture extending therethrough, the fill aperture having a first aperture portion and a second aperture portion, the first aperture portion being proximate the exterior surface and the second aperture portion being proximate the interior surface, wherein the first aperture portion is larger than the second aperture portion; and a sealing member configured to seal the fill aperture, the sealing member having a first electrically non-conductive portion and a second electrically conductive portion, said second electrically conductive portion including an extension portion embedded within the first electrically non-conductive portion, the first electrically non-conductive portion being configured to sealingly engage a portion of the second aperture portion and the second electrically conductive portion being configured to sealingly engage a portion of the first aperture portion, wherein the first electrically non-conductive portion seals the combustible gas within the enclosure and the second electrically conductive portion is configured to be welded to the enclosure by a welding process which would ignite the combustible gas if the combustible gas was exposed to the welding process.
