Abstract: A vaporizing dispenser comprising a user-activatable chemical reaction heat source and a volatile compound inside a container such that convection currents from the activated heat source volatilize the volatile compound and carry it out of the container.

Abstract: A user-activatable, flexible heat pack (100, 300) has two opposed major surfaces. (102,104/302,304) The heat pack includes a first chamber (106,306) containing a first reactant and a second chamber (108,308) containing a second reactant. The first and second reactants are adapted to react exothermically with one another when mixed. The first (106,306) and second (108,308) chambers are separated by a frangible seal (112,312). A third chamber (110,310) contains solid-to-liquid phase change material that is substantially across one of the opposed major surfaces.

Abstract: Chemical heating using a first reactant, a second reactant and a complexing agent adapted to complex reversibly with the first reactant and, thereby moderate the reaction between the first and second reactants. The heating formula is particularly well suited for heaters that are used to heat materials having relatively high viscosities.

Abstract: A disposable heating device is disclosed that includes a container having a first zone, a second zone and a third zone. A fuel is contained within the first zone and an oxidizing agent contained within the second zone. A first frangible separator disposed between the first zone and the second zone. The first frangible separator is manually operable to provide communication between the first zone and the second zone thereby defining a reaction zone. A second frangible separator is responsive to an exothermic chemical reaction within the reaction chamber. The second frangible separator is operable to provide communication between the reaction chamber and the third zone. Communication between the first zone and the second zone allows mixing of the fuel and the oxidizing agent to initiate an exothermic chemical reaction and an environmental parameter associated with the exothermic chemical reaction operates the second frangible separator.
