  • Publication number: 20160341455
    Abstract: A transport object is sealed in a sterilized sealed bag including a volume adjuster, the volume of which is changed according to a temperature change. The sealed bag is placed into a metal sealed container. The sealed container is placed into a temperature-controlled metal soaking container. In a state where the soaking container is fixed to the inside of an insulated container with an insulation material disposed around the soaking container, the internal pressure of the sealed container is maintained at a constant atmospheric pressure by changing the state of a pressure adjustment valve from a closed state to an open state, the pressure adjustment valve being provided in an air ventilation tube which is disposed to extend to the outside of the soaking container and the insulated container from the sealed container.
