Patent ID: 7448402

Claim:
A fluid storage and leak containment apparatus comprising (a) a fluid storage vessel assembly comprising at least one vessel having an interior, an exterior, and an outlet opening between the interior and the exterior; (b) a fluid flow fitting sealably connected to the outlet opening and adjacent the exterior of the at least one vessel, wherein the fluid flow fitting is adapted for withdrawing reactive gas from the interior of the vessel; (c) a containment enclosure having an interior, an exterior, an open end, and an extraction port adapted for the withdrawal of gas from the interior of the containment enclosure, wherein the open end is adapted to fit over and around the fluid flow fitting such that the containment enclosure surrounds the fluid flow fitting and is adapted to collect any reactive gas leaking from the fluid flow fitting; and (d) an attachment member connected to the containment enclosure, wherein the attachment member is adapted to removably attach the containment enclosure to the fluid storage vessel assembly and to cress the open end of the enclosure against the fluid storage vessel assembly around the fluid flow fitting; wherein the removable attachment member comprises at least one elastic body having a first end and a second end, the first end is connected to the exterior of the containment enclosure and the second end has a magnet fixed to it to provide a removable magnetic attachment to the fluid storage vessel assembly such that the elastic body is in tension.
