Heated container having chemical heating mechanism

摘要

A self-heating food container configured to hold food and to heat food within the container is provided. The container includes a body wall. A space is defined within the body wall. A chemical heater is located within the space, which upon activation, is configured to generate heat, thereby increasing the temperature of the contents cavity.

主权项

1. A self-heating assembly for food, the assembly comprising:
an outer container comprising a sidewall, a bottom wall and an inner surface defining a cavity; an inner container received within the cavity of the outer container, the inner container comprising a sidewall, a bottom wall, an inner surface and an outer surface, the inner surface of the inner container defining an interior cavity configured to hold food; a reaction space defined between the inner surface of the outer container and the outer surface of the inner container; a chemical heat source positioned within the reaction space and in thermal communication with the inner container; and an activation element configured to be manipulated by a user to trigger heat generation by the chemical heat source to heat food held within the interior cavity of the inner container, wherein the chemical heat source comprises one or more heating chemicals in a frangible and hermetically sealed shell and a solid chemically reactive material in the reaction space, wherein the activation element comprises a cutting structure located within the reaction space, the cutting structure configured to pierce the hermetically sealed shell upon manipulation of the activation element by the user, thereby allowing the one or more heating chemicals to mix with the solid chemically reactive material; and a temperature sensitive deactivation element located within the reaction space between the outer container and the inner container and configured to decrease an amount of heat generated by the chemical heater when a threshold temperature is reached within the food product, wherein the temperature sensitive deactivation element releases a quenching material at a predetermined temperature within the food product that mixes with the chemical heat source to decrease the heat generated by the chemical heat source, and wherein the temperature sensitive deactivation element comprises a ring adhered to the outer surface of the inner container.
