PROBLEM TO BE SOLVED: To select a raw material used for a cold reserving vessel and adjust its amount in manufacturing the vessel having performance close to the requirement of an object to be kept cold, and to miniaturize the vessel put in a refrigeration room. SOLUTION: A pot-shaped vessel 1 is made of a substance having inferior heat conduction, and a cup-shaped vessel 2 suitable for an inlet of the pot-shaped vessel 1 is made of a substance having excellent heat conduction. The cup- shaped vessel 2 is inserted through the inlet of the pot-shaped vessel 1, is internally provided at an adequate position, and adheres closely and is fixed. A cold insulator 3 is filled into a space formed between the pot-shaped vessel 1 and the cup-shaped vessel 2. A lid 4 may be used as required. COPYRIGHT: (C)2004,JPO
