Claim Text:
1. A portable storage device for maintaining the temperature of at least one food item contained in the device, the storage device comprising: a first container including a base and at least one side wall extending upwards from the base to an upper terminal end, such that the first container at least partially defines a receptacle, wherein the base defines a heat transfer member; a second container defining a side wall having an upper portion shaped as a substantially inverted “U” such that the upper portion of the side wall of the second container extends over the top of the upper terminal end, wherein the second container is configured to be received in the receptacle of the first container at a location adjacent the heat transfer member, the second container defining an inner surface and an opposed outer surface, wherein the outer surface of the second container is in thermal communication with the heat transfer member when the second container is disposed in the receptacle, and the inner surface defines a second receptacle that is configured to receive the at least one food item, the second container; a heat sensor disposed adjacent the heat transfer member, the heat sensor configured to transmit a signal reflecting whether an actual temperature is above or below the desired temperature; and a thermoelectric device configured to heat or cool the base of the heat transfer member depending on whether the actual temperature is above or below the desired temperature, so as to substantially maintain the heat transfer member substantially at the desired temperature.
