Abstract

A cold preserving container including an inner box forming a heat insulating chamber, an outer box, heat insulating material between the boxes, a cooling evaporating tube disposed on the outer surface of the inner box, and a cold accumulator enclosing a cold regenerative material and disposed between the evaporating tube and the heat insulating material. The cold accumulator directly contacts the evaporating tube substantially without any air therebetween and thus can be cooled rapidly and efficiently by the tube. The cold accumulator is disposed between the boxes, and thus its capacity can be easily increased, thereby increasing the cold preserving time of the container.
