Description of the Related Art Conventionally, as a long-term preservation method for living tissues such as red blood cells, platelets, white blood cells, bone marrow, and hematopoietic stem cells, a method of immersing a cryopreservation container containing living tissues in liquid nitrogen and cryopreserving them has been known. Has been adopted. When the container is cryopreserved in liquid nitrogen, usually, the cryopreservation container is damaged and the living tissue flows out, or the label attached to the cryopreservation container peels off and flows out. The cryopreservation container is housed in a plastic sheet package so as not to be damaged. Then, after sealing the opening of the package,
The cryopreservation container housed in the package is stored in liquid nitrogen. At this time, if air is present between the package and the cryopreservation container, heat conduction during the freezing of the living tissue may be hindered, which may affect the freezing speed of the cells, and the volume of the air may rapidly increase during freezing. It may decrease and the package may be damaged. For this reason, it is common practice to degas the air present inside the package and then seal the opening using a heat welding machine. As the degassing method, a method of forcibly discharging the air inside by a vacuum pump or the like, or depressurizing the inside by pressing from the outside of the package is adopted. However, in the former method, the cryopreservation container is deformed due to excessive vacuum pressure, and the thickness of the container may vary,
In the latter method, there is a problem that it is difficult to make the thickness of the container constant because of manual operation.

Need to be adjusted. In order to precisely adjust the cooling temperature, it is necessary to make the thickness of the living tissue contained in the cryopreservation container uniform over the entire surface of the container. If the thickness of the living tissue is not uniform, the cooling rate of the living tissue varies, and many living tissues may die. Also, when sealing the opening of the package with a heat welding machine, wrinkles are generated on the sealing surface, and when the container for cryopreservation containing the package is immersed in liquid nitrogen, the wrinkles on the seal surface may cause the inside of the package to enter. There is a possibility that liquid nitrogen may enter and damage the package.
