Abstract
A heat insulating box, such as a refrigerator box, comprises a heat insulator and a box member that is in contact with the heat insulator. The heat insulator is formed of a urethane foam using either HCFC-123 (CHCl.sub.2 CF.sub.3) or HCFC-141b (CH.sub.3 CCl.sub.2 F) or both as a forming agent, and the box member is formed of a styrene/acrylonitrile/butadiene terpolymer, a styrene/ethylene-.alpha.-olefinic rubbery copolymer/acrylonitrile terpolymer (AES resin), a styrene/alkyl acrylate ester containing rubbery copolymer/acrylonitrile terpolymer (AAS resin), or a mixture of the AES resin and the AAS resin.
