PURPOSE:To prevent crystallization water from evaporating outside a container when heat accumulating material is heated repeatedly by microwaves and remove incongruous sense when the material is put on the body by a method wherein a device consists of a primary container with the built-in heat accumulating material fused by heating and a secondary container covering the primary container and water is sealed in the secondary container. CONSTITUTION:A primary container 2 and a secondary container 3 are made of such material that is non-reactive and incompatible with heat accumulating material 4 at their parts being in contact with the material 4. As the material 4, material which is easily and uniformly fused by microwave heating is suitable. As water 5 sealed in the container 3, distilled water is desirable. The container 3 is sealed in the container 3 and when the container 2 is heated, the container 2 comes in contact with the water 5 sealed in the container 3 or its vapor. The vapor pressure in the secondary container becomes saturated vapor pressure at its temp. at all times, and when the container 2 is heated, the crystallization water in the hydrate sealed in the container 2 is not vaporized and do not go outside the container. The crystallization water in the hydrate is evaporated outside just after the water 5 sealed in the container 3 is evaporated from the container 3 to the outside. |
