Description

  The present invention relates to a cool storage body in which a cool storage agent is sealed in a cool storage agent container including an identification tool. In particular, the present invention relates to a cold storage body equipped with an identification tool that can identify cold storage capacity and can be attached to the outer surface of a cold storage agent container.

Conventionally, regenerators have been widely used to keep food products and medicines at an optimum temperature, and are repeatedly used. When enclosing the regenerator in the container, the container was molded with a synthetic resin that can visually recognize the internal regenerator so that the amount of the regenerator can be easily visually confirmed, and the regenerator was colored. The thing is proposed (refer patent document 1).
Moreover, in order to distinguish the cool storage ability of a cool storage agent according to the object for freezing whose cold storage temperature is about -18 degreeC, and the refrigerating use whose cold storage temperature is about 3 degreeC, there exist some which are colored in the cold storage agent.

Furthermore, for the purpose of making it possible to visually recognize the cold storage state, a cold storage agent made of a composition for keeping cold in which discoloration during cooling is visible has also been proposed (Patent Document 2). Before freezing, for example, the cold storage agent is blue, but after freezing, it becomes white or light white with a bluish tint, and the cooling state can be visually confirmed. With these cold storage agents colored, it was possible to distinguish the cold storage capacity at room temperature.
However, even if it is a regenerator with different regenerative capacity as described above, or a regenerator that can visually recognize the regenerator state, in the state of the regenerator after freezing, it is white or lightly colored white. Therefore, the cold storage agent still in the frozen state could not be distinguished, and there was a problem of causing a mistake in the storage of the cold storage agent.
