Abstract:
A fuel supply container for a vaporizable liquid; flame producing fuel, the container comprising:a side wall with opposite ends, a container bottom at one end of the side wall and a lid at the other end of the side wall; the container having an exposed exterior, exposed to heat produced by flame at a vapor tube; a valve in the lid, a vapor entrance in the container leading through the valve, with the container orientable so that the vapor entrance is in a vapor pocket above a pool of liquid fuel under pressure in the container; a vapor tube which communicates to the valve, the vapor entrance is an inlet to the tube; the side wall of the container is of such material and is sufficiently thin that when the container is pressurized at least to a level sufficient to supply fuel through the valve for production of a flame, the side wall is rigid against both deformation of the side wall by normal finger pressure of an adult and crushing of the side wall by normal hand pressure of an adult, and when the pressure in the can is at most slightly above atmospheric pressure, the can side wall may be deformed by normal finger pressure of an adult, and be crushed by normal hand pressure of an adult, with the valve open permitting exhaustion of vapor pressure in the can and the sidewall is also sufficiently thin that burning of the vaporized fuel at the tube outlet heats the container side wall and through the heating of the sidewall, heats the liquid fuel in the container to improve the flame.
