A pressure relief device comprising a body including an exterior surface, a cavity, an inlet, an outlet, and an aperture, each of the inlet, the outlet, and the aperture opening into the cavity, a temperature sensitive bonding element and a valve, disposed within the cavity and extending through the aperture, including a sealing member and a cap, the cap being joined to the exterior of the body by the temperature sensitive bonding element, and the sealing member being configured to seal the inlet when the cap is joined to the exterior surface of the body. The pressure relief device as claimed in claim 16 , wherein the body further includes a retainer configured to prevent the valve from separating from the body when the cap becomes disengaged from the body. A pressure relief device comprising a body including an exterior surface, a cavity, an inlet, and an outlet, each of the inlet and the outlet opening into the cavity, a temperature sensitive bonding element, a valve, disposed within the cavity, including a valve retainer and a sealing member, the valve retainer being coupled to the sealing member, the valve retainer being joined to the body by the temperature sensitive bonding element, and the sealing member being biassed into a sealing relationship with the inlet.

1. A pressure relief device comprising:a body including an exterior surface, a cavity, an inlet, an outlet, and an aperture, each of the inlet, the outlet, and the aperture opening into the cavity;a temperature sensitive bonding element; anda valve, disposed within the cavity and extending through the aperture, including a sealing member and a cap, the cap being joined to the exterior of the body by the temperature sensitive bonding element, and the sealing member being configured to seal the inlet when the cap is joined to the exterior surface of the body. 2. A pressure relief device as claimed in claim 1, wherein the body further includes a retainer configured to prevent the valve from separating from the body when the cap becomes disengaged from the body. 3. A pressure relief device as claimed in claim 1, wherein the valve is sealingly disposed within the cavity between (i) the inlet and the outlet, and (ii) the aperture. 4. A pressure relief device as claimed in claim 3, wherein the valve includes a sealing member disposed between (i) the inlet and the outlet, and (ii) the aperture. 5. A pressure relief device as claimed in claim 2, wherein the valve is sealingly disposed within the cavity between (i) the inlet and the outlet, and (ii) the aperture. 6. A pressure relief device as claimed in claim 5, wherein the valve includes a sealing member disposed between (i) the inlet and the outlet, and (ii) the aperture. 7. A pressure relief device as claimed in claim 1, wherein the valve is biassed away from the valve seat. 8. A pressure relief device as claimed in claim 7, further comprising a resilient member disposed within the cavity and configured to urge the valve into an unsealing relationship relative to the inlet. 9. A pressure relief device as claimed in claim 8, wherein the body further includes a retainer configured to prevent the valve from separating from the body when the cap becomes disengaged from the body. 10. A pressure relief device as claimed in claim 9, wherein the valve is sealingly disposed within the cavity between (i) the inlet and the outlet, and (ii) the aperture. 11. A pressure relief device as claimed in claim 10, wherein the valve includes a sealing member disposed between (i) the inlet and the outlet, and (ii) the aperture. 12. A pressure relief device comprising:a body including a cavity, an aperture, an inlet, and an outlet, each of the aperture, inlet, and the outlet opening into the cavity;the body including an exterior surface positioned distal to the inlet;a temperature sensitive bonding element adapted to melt at temperatures above a predetermined temperature;a valve disposed at least partially within the cavity and including a sealing member;the valve being movable between a closed position, in which the inlet and the outlet are sealed from each other by the sealing member, and an open position, in which the inlet is in fluid communication with the outlet; andthe valve including at least one valve bonding surface adapted to mate with the exterior surface of the body when the valve is in the closed position, such that the temperature sensitive bonding element is receivable therebetween, to bond said at least one valve bonding surface to the exterior surface when the temperature of the temperature sensitive bonding element is below the predetermined temperature;whereby, upon the temperature of temperature sensitive bonding material exceeding the predetermined temperature, the temperature sensitive bonding material melts, permitting disengagement of said at least one valve bonding surface from the exterior surface, such that the valve is movable from the closed position to the open position. 13. A pressure relief device as claimed in claim 12 in which the valve includes a cap portion extending outside the cavity and including said at least one valve bonding surface, and the body additionally includes a retainer configured to prevent the valve from exiting the body when the cap is disengaged fro m the body. 14. A pressure relief device as claimed in claim 12, wherein the valve is sealingly disposed within the cavity between (i) the inlet and the outlet, and (ii) the aperture. 15. A pressure relief device as claimed in claim 14, wherein the valve includes a sealing member disposed between (i) the inlet and the outlet, and (ii) the aperture. 16. A pressure relief device as claimed in claim 13, wherein the valve is sealingly disposed within the cavity between (i) the inlet and the outlet, and (ii) the aperture. 17. A pressure relief device as claimed in claim 16, wherein the valve includes a sealing member disposed between (i) the inlet and the outlet, and (ii) the aperture. 18. A pressure relief device as claimed in claim 12, wherein the valve is biassed away from the valve seat. 19. A pressure relief device as claimed in claim 18, further comprising a resilient member disposed within the cavity and configured to urge the valve into an unsealing relationship relative to the inlet. 20. A pressure relief device as claimed in claim 19 in which the valve includes a cap portion extending outside the cavity and including said at least one valve bonding surface, and the body additionally includes a retainer configured to prevent the valve from exiting the body when the cap disengaged from the body. 21. A pressure relief device is claimed in claim 20, wherein the valve is sealingly disposed within the cavity between (i) the inlet and the outlet, and (ii) the aperture. 22. A pressure relief device as claimed in claim 21, wherein the valve includes a sealing member disposed between (i) the inlet and the outlet, and (ii) the aperture.
