Cup warmer
First Claim
1. A cup holder for a cardboard cup, comprising:
- a heating surface configured to receive the cardboard cup;
an outside surface concentric with the heating surface;
a heating element disposed between the heating surface and the outside surface, wherein the heating element is configured to heat the heating surface to a heating temperature; and
a pressure sensitive switch located in a bottom portion of the heating surface, wherein the pressure sensitive switch allows a current to run through the heating element in response to the cardboard cup exerting a toggle pressure on the pressure-sensitive switch.

Abstract
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.

11. A cup holder, comprising:
-
a cavity having a horizontal surface and a substantially vertical surface, wherein the cavity is configured to receive a cardboard cup; an outside surface that is substantially concentric with the substantially vertical surface of the cavity; a heating element disposed proximate to the substantially vertical surface and between the cavity and the outside surface, wherein the heating element is configured to heat the substantially vertical surface of the cavity; and a pressure-sensitive switch disposed within the cavity, wherein the pressure-sensitive comprises a first position and a second position, wherein the cardboard cup depresses the pressure-sensitive switch, thereby toggling the pressure-sensitive switch from the first position to the second position, and wherein the pressure-sensitive switch in the second position allows a current to run through the heating element. - View Dependent Claims (12, 13)

14. A system, comprising:
-
a cardboard cup having a base and a wall, wherein the cardboard cup is configured to hold a beverage; and a cup holder configured to hold the cardboard cup, wherein the cup holder comprises; a pressure-sensitive switch oriented vertically within the cup holder, wherein the pressure-sensitive switch is configured to be toggled in response to the cardboard cup being placed within the cup holder; and a heating element configured to heat the beverage through at least one of the base and the wall of the cardboard cup, in response to the cardboard cup toggling the pressure-sensitive switch. - View Dependent Claims (15, 16, 17, 18, 19, 20)
