Container for transporting temperature sensitive materials

A heated transportation container is described. The container consists of at least a body and a lid, the body being generally cuboid and having one or more side walls and a base which together define an internal chamber over which the lid can be placed to close the container. Inside the chamber is disposed a pre-frozen or refrigerated cooling pack to keep the temperature low and in accordance with the invention, a laminar heating, panel is affixed, to at least a portion of the inner surface of one of the side walls and/or to base, said laminar panel comprising an electrically resistive component and electrical connections through which power can be delivered to said laminar panel. Battery powered control circuitry is also provided which communicates with a temperature measuring device disposed within the chamber. In a preferred embodiment, the control circuitry also includes user adjustable means for setting the desired temperature within the chamber and acts to deliver electrical power to the laminar panel to heat same and thus increase the temperature inside the chamber when the temperature measuring means indicates that the temperature is below a desired pre-set or user adjusted temperature.
