Cold preserving container

Abstract

A cold preserving container including a goods container space, a dish-like member above the space, a cold accumulator enclosing a cold regenerative material and disposed in the dish-like member, a heat insulating wall forming an air path between the wall and the dish-like member, and a blower circulating air between the air path and the goods container space. The cold accumulator cools the air in the disk-like member, the cooled air can fall down into the goods container space and circulate between the space and the air path by driving the blower. Since the cooling of the air in the space is controlled by the drive control of the blower, the temperature of the inside air can be easily controlled and maintained at the desired temperature despite variations in outside air temperatures. Moreover, since the cold accumulator is disposed in the dish-like member, the stable structure of the cooling portion of the container can be easily achieved, thereby providing a container suitable for a long distance transportation.
