Cold storage body and container provided with cold storage body

摘要

The present invention provides a cold storage body capable of keeping a cold object while keeping freshness, and a container provided with the cold storage body. A regenerator 1 includes a regenerator and a low thermal conductivity member 20 that is integrally held with the regenerator, and the low thermal conductivity member side is a contact surface with an object to be cooled. did. It becomes possible for a cool storage body to cool a to-be-cooled object through a low thermal conductivity member. Thereby, the cooling-heat efficiency with respect to the to-be-cooled material of a cool storage agent can be weakened, and it can prevent that a to-be-cooled material is frozen. Moreover, since a cool storage agent and a low heat conductivity member are hold | maintained integrally, it can prevent that a cool storage agent and a low heat conductivity member shift. Thereby, it is prevented that the cool storage agent is brought into direct contact with the object to be cooled, and the cold storage is stably kept in a state where freezing of the object to be cooled is prevented. Therefore, it is possible to keep the cold object while keeping the freshness of the cold object. [Selection] Figure 3
