A container is disclosed for maintaining its contents at a desired temperature for an extended period of time such as for use in shipping contents in a frozen condition. The container includes an outer shell which is substantially airtight and which has an inner surface; a passive heat exchange medium; a support structure for the heat exchange medium; and means for maintaining an air space between the contents of the container and substantially the entire inner surface of the outer shell of the container and between the contents of the container and the support structure for the heat exchange medium for allowing convection current to develop in the air space which circulates past the heat exchange medium and maintains a substantially uniform temperature around the contents of the container.

A container for maintaining its contents at a desired temperature for an extended period of time, comprising: an outer shell which is substantially airtight and which has side walls and inner surfaces; a passive heat exchange medium; a support structure for the heat exchange medium; and means for maintaining a space between the contents of the container and substantially the entire inner surface of the sides and bottom of the outer shell of the container and between the contents of the container and the support structure for the heat exchange medium for allowing convection in said space to maintain a substantially uniform temperature throughout the contents of the conter; said spacer means comprising blocks, each block having a side which faces said side wall of said container and a side which faces said contents, each of said sides of said blocks having a surface area which is less than 70% of the surface area of the adjacent side wall of said container.
