A metallic product compartment of a single-use, self-heating container has melted onto one or more of its surfaces and re-solidified a shaped fusible material containing a reaction suppressant. A method of manufacturing includes providing the product container, positioning the fusible material, as a solid, in contact with a metallic wall of the container, heating at least a portion of the metallic wall with an electromagnetic induction heater to at least partially melt a portion of the fusible material, and enabling the melted portion of the fusible material to cool and re-solidify, thereby adhering the fusible material to the metallic wall.

A self-heating assembly includes a product tray for containing a product to be heated and a heater tray outside the product tray and configured relative to the product tray to define a reaction space between the heater tray and the product tray. A frangible container made of a shrink film material is inside the reaction space. The frangible container contains a first reactant that is a liquid. A second reactant is outside the frangible container. The first and second reactants are configured to react exothermically upon contact with each other.

An apparatus for heating a product includes a storage compartment for a product to be heated and a heater module physically and thermally coupled to the storage compartment. The heater module has a housing that defines a reaction chamber. A rigid barrier is inside the reaction chamber and defines first and second portions thereof. A first reactant is inside the reaction chamber, and a flexible bag (with a second reactant) is in the first portion of the first chemical reactant. The first and second reactants react exothermically upon contact. A piercing element can pierce the flexible bag. After piercing, the a fluid path and one or more fluid channels carry the second reactant to a section of the first portion of the reaction chamber away from where the flexible bag is located.

A unibody heater module is disclosed having an end cap and a base, wherein the base of the heater canister is filled with a solid-state reaction mixture. Twist-to-activate heater starting functionality is embedded directly into the unibody heater module. A reactive starting pellet is embedded into the upper surface of the compacted solid-state reaction mix. The plunger head of a firing pin passing through the center of an internal metal spacer is held a small distance away from the upper surface of the starting pellet. When the user activated CUI is rotated, the base of a cam pushes on one end of a firing pin protruding through a small hole in the end cap of the unibody heater module. The opposite end of the plunger plunges into the starter pellet so as to initiate heater activation in response to operation of the CUI by the user.

A warming apparatus that has a formable apparatus and a chamber coupled to the formable apparatus and configured to fluidly contain a heating agent. Wherein the formable apparatus is movable to reposition the chamber to heat a vessel.

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 container includes a first substance and a second substance that are adapted to produce an exothermic reaction upon contact with each other, a soluble material between the first substance and the second substance, a frangible membrane physically separating the second substance from the soluble material, and a means for rupturing the frangible membrane.

The formula of the flameless automatic food heating agent comprises 1 to 5 parts of aluminum powder, 3 to 10 parts of carbon powder, 5 to 25 parts of magnesium powder, 10 to 25 parts of iron powder and 1 to 5 parts of anticoagulant. The preparing of the flameless automatic food heating agent bags (3) comprises the following steps: placing two pieces of food heating agent bags (3) in two sides of a sealed food packaging (2) before putting into a water-proof heating bag (1); adding water into the water-proof heating bag (1) to let food heating agent bags (3) to absorb water; bending an opening side of the water-proof heating bag (1) to seal the opening side; vaporizing water in the water-proof heating bag (1); placing the water-proof heating bag (1) for 10 to 15 minutes; heating food in the sealed food packaging (2) to 60 C. to 80 C.

The present invention related to a container for food and other products, where said container comprises: An upper compartment or part and a lower threaded lid; in the upper compartment is placed the contents of the product that can be food, and others. The lower threaded lid is interchangeable and allows the reuse of the upper compartment, and the arrangement of the upper compartment in an extended manner and under the upper compartment allows easy, quick and practical interchangeability of the lower threaded lid, without needing to flip the upper compartment in order to place or remove it. Likewise, the upper threaded lid is protected by a security seal at the junction between the upper threaded contour and said upper threaded lid. The package or container has at least one flexible and adaptable handle. Between the upper compartment and the inner container there is a free space through which the heat flows and surrounds the outside of the entire inner container, which holds the content of the product. The lower threaded lid has an integral mechanism of compounds that houses the chemical compounds that allow food to be heated and remain hot; said chemical compounds are calcium oxide or calcium chloride and water, separated by a breakable sheet and/or a breakable container. The calcium oxide or calcium chloride and the breakable water container are placed separately, as well as at least one striking mechanism for breaking the water container, allowing the elements to combine, producing an exothermic reaction. The lower threaded lid is joined to the upper compartment through a threaded connection and optionally an adhesive tape that makes it possible to maintain the temperature and avoid possible leaks of the content that is inside the container. There are three optional mechanisms for activating the self-heating device.
