Can with integrated heat source for foodstuffs has chambers in bottom of can holding components which interact with each other to generate heat by chemical reaction

摘要

An expendable heat source is integrated in the bottom(G) of a preserved food can. The bottom of the can has chambers within which are contained components(B,C) which upon contact with each other create a chemical reaction. The coming into contact is effected by twisting the chambers to open passages. The reaction heats up the food in the can to a consumption temperature. Only one chemical reaction per can is possible.
