Abstract
A combustible gas inflator and a method for filling and sealing the inflator are provided. The inflator includes an enclosure configured to receive and store the combustible gas under pressure. The enclosure has an outer wall comprising an exterior surface, an interior surface, and a fill aperture extending therethrough. The fill aperture has a first aperture portion and a second aperture portion. The first aperture portion is proximate the exterior surface and the second aperture portion is proximate the interior surface, wherein the first aperture portion is larger than the second aperture portion. The inflator further includes a sealing member configured to seal the fill aperture. The sealing member has a first portion and a second portion. The first portion is configured to sealingly engage a portion of the second aperture portion and the second portion is configured to sealingly engage a portion of the first aperture portion. The first portion seals the combustible gas within the enclosure and the second portion is configured to be welded to the enclosure by a welding process that would ignite the combustible gas if the combustible gas were exposed to the welding process.
