A cup holder comprises a heating surface that is configured to receive a cardboard cup. The cup holder has an outside surface that is concentric with the heating surface. A heating element is disposed between the heating surface and the outside surface, and the heating element is configured to heat the heating surface. Insulation may be located between the heating surface and the outside surface, and the insulation may be configured to maintain the outside surface at an outside temperature lower than a heating temperature of the heating surface. The cup holder further comprises a pressure-sensitive switch located in a bottom portion of the heating surface. The pressure sensitive switch may allow a current to run through the heating element in response to the cardboard cup exerting pressure on the pressure-sensitive switch. |
