Abstract
A heated container for transport of prepared hot food has a combination of an electric heating element with an insulation layer comprising metal foil layers and fiber layers. The combination of metal foil layers, which spread the heat from the heating element, and the fiber insulation layers provides an efficient food transport container having sufficiently low power requirements to enable powering the heater element from an automotive 12 volt system while maintaining a food temperature inside the container at about 150° F.
Claims12
A food transport container comprising:
- walls forming an enclosure wherein at least a portion of at least one wall contains an electric heating element positioned between two metal foil layers;
- a layer of fiber insulation positioned on one of said metal foil layers;
- and
- a third metal foil layer positioned on the fiber insulation layer.
A method of constructing a heated food transport container comprising:
- assembling an electric heater element between two metal foil layers, a fiber insulation layer on one of the metal foil layers and a third metal foil layer on the other side of the fiber insulation layer;
- and
- constructing an enclosed container wherein the above assembly comprises at least one wall of the container and wherein the metal foil and heater element side faces the interior food area and the fiber insulation metal foil side faces the exterior of the container.
