Title:
A CANISTER FOR AN OXYGEN GENERATION CELL
Document Type and Number:
WIPO Patent Application WO/2005/107876
Kind Code:
A2
Abstract:
A canister (13) for use with a chemical oxygen generation cell (10). In some embodiments, the canister (13) includes two main canister assemblies. One assembly (28) houses the briquette (19), the ignition cone (22), and one or more filters (16). A second assembly (31) houses a thimble (55) and one or more filters (16). Once the components are placed within each assembly, the two assemblies can then be easily joined together to form the cell (10). In some embodiments, the sealed canister (13) is constructed with at least one weakened area (39) along at least one canister wall. Upon premature activation of the cell (10), pressure within the sealed canister (13) causes at least one controlled rupture in the weakened area (39) of the canister to vent gases and prevent an explosion.
