Abstract: 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.
Abstract: A conductive element useable as a resistance heater comprises a carbonized fabric (12) which has electrical terminals (18, 20) connected thereto and is encapsulated in or sandwiched between layers of plastic insulating material. The element generally is flexible and can be embodied in for example blankets for animals, vehicle seats and clothing. It is preferably provided with an electrical control circuit for controlling the temperature to which the fabric heats.
