Patent ID: 7694840

Claim:
A storage vessel for storing a substance, the storage vessel comprising: a plurality of individual storage chambers assembled so as to be capable of withstanding pressures greater than atmospheric, wherein at least a first individual storage chamber is adjacent to a second individual storage chamber, thereby creating at least first and second adjacent chambers, and the first and second adjacent storage chambers are each formed from a pair of plates, the pair of plates being spaced apart a predetermined distance by a plurality of surface features extending from at least one surface of at least one of the pair of plates, the surface features creating a circuitous fluid flow path that restricts a rate of flow of the substance through the storage vessel; a peripheral seal, the peripheral seal being formed along a periphery of at least one of the pair of plates in at least one of the plurality of individual storage chambers and joining the pair of plates to form the at least one of the plurality of individual storage chambers, wherein the peripheral seal is formed to fail or crack prior to a remainder of the vessel in an impact; and at least one passageway between the first adjacent chamber and the second adjacent chamber, allowing the substance to move from the first adjacent chamber to the second adjacent chamber.
