Abstract: A self-heating container and a method of manufacturing the container. The container has a simple structure in which the metallic outer body holds the consumable product, and a metallic inner body and plastic housing contain the two components which react to produce the heat for the self-heating function. A lower lid is crimped over flanges on the lower ends of the inner body and the outer body, forming a double seal. When a flexible portion of the housing is pressed, a seal is punctured, causing the two components to mix and generate heat through an exothermic chemical reaction which heats the contents of the container.

Abstract: The invention comprises an outer metallic body containing a product for consumption after heating and a second container which holds a reagent and receives a heating module formed by a housing which holds another reagent and is closed by a seal piercable by the pressure from the fingers before consumption of the product. Useful for preparation of packaged products which can be rapidly heated using an integrated heating module.
