Abstract
A container capable of heating its content when ignited has a container containing Japanese sake, coffee, soup or the like and an exothermic material storage chamber projected into the container. A self-combustible exothermic material consisting of a mixture of oxidant such as potassium permanganate and a combustible material such as iron powder, ferrosilicon powder or the like is charged into an innermost portion of the storage chamber. A heat insulating layer made of inorganic porous material is disposed adjacent to the exothermic material and ignition means for igniting the exothermic material is extended from the exterior of the container to the exothermic material.
Claims10
A self-heating container comprising:
- a container for containing a substance to be heated;
- an exothermic material storage chamber which is made of metal and is projected into the interior of said container;
- a non-fusible self-combustible exothermic material charged at the innermost portion of said exothermic material storage chamber and located substantially in the core portion of said container;
- a heat insulating layer of a porous inorganic material disposed outwardly adjacent to said exothermic material;
- and
- a fuse comprising a bundle of metal fibers or carbon fibers impregnated with a self-combustible agent having a leading end extending through the heat insulating layer and connected to said exothermic material for igniting said exothermic material.
