Abstract: A method and apparatus for a self-contained heating vessel having enhanced efficiency and safety features. In one embodiment, the vessel includes a chamber for containing fuel; a burner assembly for burning the fuel; a fuel delivery mechanism that delivers the fuel from the chamber to the burner assembly; and a container disposed adjacent to the heat exchanger assembly, the container including an opening to an interior portion of the container. In other aspects, the vessel includes an ignition assembly operatively connected to said burner assembly and a heat exchanger assembly disposed adjacent to the burner assembly. In further aspects, the vessel includes a displacement sensor to prevent operation when displaced from an intended operating position and a pressure regulator that controls delivery of fuel to the burner assembly to maintain a substantially constant heating profile over a varying temperature range.

Abstract: A cooking utensil includes a container having a peripheral wall at its upper end outwardly circumscribing its open top and defining therewith an annular reservoir for receiving a quantity of water. A lid overlies the container open top and includes a depending skirt dimensioned to become partially immersed in the reservoir water and to divide the upper part of the reservoir into an inner section, and an outer section communicating with the inner section via the bottoms of the two sections The open top of the container is formed with a triangular slot permitting a small quantity of liquid to be automatically drawn from the reservoir into the interior of the container upon cooling of the container.
