A container (10) for holding a supply of compressed fluid such as carbon dioxide has a length of tube (12) formed into a multi turn helical coil (14). A first valve (16) is provided at the lowest end (18) of the coil (14) for controlling the flow of fluid out of the container (10). A thermal insulating setable foam (20) envelopes the tube (12) and coil (14), though not the valve (16) which is disposed outside of the foam (20). A strap (26) extends about the coil (14) to bind the turns of the coil (14) together for added safety and strength. Coil (14), and setable foam (20) are disposed within a heat insulating housing (28). Inlet valve (22) is attached to an upper end of the tube (12) proximate the highest one of the turns of the coil (14).
