Shrink wrapped generant cartridge

摘要

A hermetically sealed cartridge (10) of gas generating wafers (12) or pellets includes a shrink wrapped film (14) of a synthetic resin polymer material and end caps (18) one of which may include a thinned central area for positioning adjacent an igniter. If the gas generant is in the form of wafers (12) they may have central bores which form a bore (30) extending throughout the cartridge in which an igniter booster charge (28) is situated. The booster charge (28) may be contained by a rupturable disc (32) positioned between two adjacent wafers (12) to concentrate the effect of the booster charge close to one end of the cartridge. <IMAGE>
