The Patent Description & Claims data below is from USPTO Patent Application 20060171863, Method and apparatus for controlled production of a gas.

1. An apparatus for containing a chemical reaction generating an oxygen-rich gas, comprising: a chamber having one or more flexible walls capable of being displaced inwardly with respect to the chamber without breaking or tearing; one or more containers within the chamber having a wall comprising a frangible material and configured to contain a chemical reactant; a chemical reactant for generating oxygen contained by the one or more containers; and wherein at least a portion of the one or more chamber walls severs at least a portion of the frangible material comprising the wall of the one or more containers when the chamber wall is displaced inwardly, releasing or exposing at least a portion of the chemical reactant within the chamber.

2. The apparatus of claim 1, wherein at least a portion of the flexible walls of the chamber comprise a laminate material, sealed along at least a portion of the periphery of the chamber, the flexible walls of the chamber configured to transfer pressure to the one or more containers within the chamber to sever at least a portion of the frangible material comprising the one or more containers, releasing or exposing at least a portion of the chemical reactant within the chamber.

3. The apparatus of claim 2, wherein at least one or more portions of the laminate material is selected from among the group of aluminum, polypropylene, polyethylene terephthalate, and polyethylene/high-density polyethylene.

4. The apparatus of claim 1, further comprising a plurality of containers within the chamber containing a plurality of chemical reactants for generating oxygen within the chamber when the plurality of chemical reactants is released by the plurality of containers within the chamber.

5. The apparatus of claim 1, wherein a plurality of the containers are within the chamber and at least one of the containers does not contain a chemical reactant.

6. The apparatus of claim 5, wherein the container that does not contain a chemical reactant contains a quantity of air at ambient pressure.

7. The apparatus of claim 1, wherein at least a portion of the flexible walls of the chamber comprise a laminate material, and at least one of the one or more containers within the chamber comprises one or more seals further comprising a pressure-frangible adhesive.

8. The apparatus of claim 1, wherein the one or more containers within the chamber comprise one or more walls secured together with a seal that opens in response to increasing the pressure within the one or more containers.
