To enable efficient door-to-door transportation of perishable goods, precision equipment, etc., when they are air-freighted, by the use of an inexpensive, lightweight vessel capable of being recycled, while keeping the quality of those commodities.

A paper-made vessel 2 is fixed, through the medium of a cushioning support member 3, inside a thermal insulation vessel 1 provided with a through hole 5 so that spaces for communication separated by the support member 3 are provided. If the vessel is intended for cold insulation, the through hole 5 is fitted with a check valve, so that spaces for communication are filled with low-temperature carbon dioxide gas that sublimes from dry ice. If the vessel is intended for use in transporting precision equipment, etc., a dehumidifier device so adapted as to be comprised of a container having a plurality of openings charged with desiccating agent in a ventilable way is fitted onto the through hole 5 of the thermal insulation vessel 1.
