<p>PURPOSE:To obtain a safe container which neither melts nor burns down even when heat generating material in the container is hydrated and gives off much heat to produce high temperature, by placing the heat generating material on a barrier laid on the inner bottom of the container or wrapping the heat generating material with water-absorbing paper or paper which dissolves after absorbing water. CONSTITUTION:A container 3 composed of material such as polypropylene has hydrated heat generating material 5 whose heat source is hydrated quick line, and a barrier 6 which is placed between the container 3 and the hydrated heat generating material 5, and which is composed of the following material: heat-resistant material such as metal foil, heat-resistant paper, ceramic paper, a glass sheet (wool cloth), and synthetic resin film; material becoming heat-resistant after absorbing water or melting such as hygroscopic paper, unwoven cloth, textile, water-absorbing paper, and wood; starch paper which dissolves after absorbing water; and material which becomes heat-resistant after absorbing water such as PVA paper and water-absorbing resin paper. The polypropylene container with heat-resistant at 120 deg.C does not melt even when the temperature of the hydrated heat generating material becomes from 120 deg.C at least to 200 deg.C in the extreme case.</p> |
