Cold preserving container
First Claim
1. A cold preserving container comprising:
- first heat insulating walls surrounding a goods container space;
an upwardly-opening, dish-like member positioned above said goods container space;
a cold accumulator positioned in said dish-like member;
cold regenerative material enclosed in said cold accumulator;
a second heat insulating wall covering and spaced above said dish-like member;
an air path positioned between said second insulating wall and said dish-like member and having air path end portions, said air path communicating at said air path end portions with said goods container space; and
a blower means for circulating air between said air path and said goods container space.

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.
