Abstract: A water storage and delivery assembly includes stackable compartments, each compartment having a planar bottom wall, opposed side walls, and opposed end walls, forming a reservoir. Frusto-conically shaped conduits having open large first ends are fixed to peripheries of openings in the bottom walls, and open smaller second ends are disposed below upper edges of the side and end walls. The assembly further includes a bottom-most compartment of the same construction but having no openings in the bottom wall thereof. Water poured into a first conduit is flowable through a plurality of first conduits to the bottom-most compartment while air escapes upwardly through a series of second conduits, the water rising until all the compartments of the assembly are filled. Each compartment is provided with an outlet operable to permit the water to travel from a compartment to an exothermic mass.

Abstract: A self-heating group meal assembly and method of using same. In one embodiment, the assembly comprises a plurality of heating trays, each heating tray having a plurality of standoffs extending upwardly from the bottom thereof. The assembly also comprises a corresponding plurality of heater assemblies, each heater assembly being positioned within a tray on top of the standoffs so as to define a reservoir between itself and the bottom of its tray. Each heater assembly comprises a sturdy polymeric sheet of material shaped to define a plurality of pockets, an exothermic chemical heater material packaged into each of the pockets and a sheet of porous non-woven scrim attached to the bottom surface of the polymeric sheet and used to seal the pockets. The exothermic chemical heater material comprises a Mg-Fe alloy from which all activating electrolytes have been omitted to prevent inadvertent activation of the alloy in the event of water immersion.
