A container and two substances contained in the container apart from each other and in contact with each other to cause an exothermic reaction or a cooling reaction, and one of the two substances is a liquid,
The other was solid and the liquid was sealed in a plastic bag. When heating the contents, insert a pin that penetrates the lid from the bottom that closes the lower end opening of the container into the container and pierce the bag with this pin to bring the two substances into contact with each other to cause an exothermic reaction. I was letting it.

However, in the conventional container, the liquid substance and other substances are not brought into contact with each other quickly, and it takes time for both substances to come into contact with each other, so that an exothermic or endothermic reaction starts and ends. There was a problem that it took a lot of time until.

Therefore, as a self-heating container that solves such a problem, as a cylindrical body having a lid having a hole formed at the lower end and a cylindrical body lower part, the peripheral portion of the hole in the lid is arranged. Attached vertical U-shaped metal utensil with inverted U-shape, quicklime stored in the utensil, water-sealed bag also placed in the utensil, and perforation with a plurality of protrusions in the water-sealed bag It has been proposed that the lower end opening of the container is closed with a sealing lid (Shokaisho 62).
