Insulated shipping container

摘要

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.
