The present invention may be used for self-heating edible fluids without an external heating source, and no or minimal leakage or spilling. It may consist of a fully sealed container body that prevents the leakage or mixing of an activation substance and edible fluid. A body inside of the container may behave as conductive wall separating the activation substance and edible fluid to prevent mixing. The invention includes a chemical pack tool that may be punctured into the container and seal the punctured hole so the is no leakage. As the exothermic reaction takes place, a built-in vent or existing one-way valves/vents may be used to prevent excess pressure build up, and then pushed back in to fully seal the container again when it is no longer needed.

A non-electric heating apparatus with an upper and lower section. The upper section includes a cupholder and surrounding upper reaction chamber with dry reaction materials therein. The lower section includes a lower housing, a lower outer shell with lower outer shell apertures, a lower inner shell with lower inner shell apertures, a lower reaction chamber with dry reaction materials surrounding the lower housing, a platform within the lower housing, a bladder containing water on the platform, and bottom. The platform is movable within the housing and the lower outer apertures are structured to rotatably align with the lower inner apertures. Water may be expelled from the bladder into the upper reaction chamber when the platform is moved within the lower housing. The upper reaction chamber produces an exothermic reaction when water enters. The lower reaction chamber creates an exothermic reaction when airflow enters through the aligned inner and outer apertures.

A sealed package is disclosed for a self-heating assembly that produces heat by virtue of a liquid reactant reacting exothermically with a solid reactant to heat a product. The sealed package includes an outer container, a lower support structure (e.g., of open cell foam) within the outer container, a layer of the solid reactant above the lower support structure and within the outer container, an upper structure (e.g., of open cell foam, as well) above the solid reactant and within the outer container, and an upper layer that is permeable to liquid and that extends across an otherwise open top of the outer container above the upper structure.

A self-heating product pouch has a first thin flexible material that surrounds and defines a product compartment. A second thin flexible material is coupled to an outwardly-facing surface of the first thin flexible material to define a first heater compartment that is outside, but thermally coupled to, the product compartment. A first thin porous substrate inside the first heater compartment. A granular reactant is distributed throughout the first thin porous substrate. A frangible container is inside the first heater compartment. A liquid reactant is inside the frangible container. The granular reactant and the liquid reactant are adapted to react exothermically upon contact with one another.
