を予測することは、相当に困難である。Conventionally, it is known to attach a temperature indicating label to the surface of the above-mentioned coolant (the surface of the bag). However, since the temperature of the coolant surface is greatly influenced by the outside air temperature and the wind speed, the temperature of the coolant is kept cool. It is difficult to accurately grasp the temperature of the agent, therefore, it is not easy to accurately grasp the temperature of the cooling and cooling agent during the use of the above-mentioned coolant, and it is possible to predict the usable time thereafter. Quite difficult.

材の交換時期に達したことを容易に知り得る。The cooling material according to the present invention is used in a state in which the cooling material is cooled to a predetermined temperature in a refrigerator or a freezer and is brought into contact with an object to be cooled. In this case, if the minimum temperature of the cooling / cooling agent required for keeping cold is approximately T 1 , the thermochromic pigment having a color changing temperature of approximately T 1 is used. When the temperature of the cooling and cooling agent reaches almost T 1 , it can be easily known from the discolored state of the cooling agent that it is time to replace the cooling agent.

It is possible to accurately predict the end of time, or the available time thereafter during use.
