Title: Heating and dispensing apparatus

Abstract: A dispenser for use in dispensing a product in heated condition from a pressurized container. The dispenser includes a main housing for removably receiving and holding the container and a heat exchanger assembly mounted in the main housing and spaced apart from the container. The heat exchanger assembly comprises a cup-like mass of a heat conductive material and includes an elongated passageway in its wall of a depth substantially equal to that of the wall and extending from the inlet to the outlet of the heat exchanger assembly. The product is directed in a single predetermined direction through the elongated passageway from the inlet to the outlet of the heat exchanger assembly. Further, an electrical heater is disposed along the inner wall of the cup-like mass and a circuit for connecting the heater to a source of power is provided. A thermostatic switch in the circuit is disposed within the heat exchanger assembly to disconnect the power source when the heat exchanger assembly reaches the desired temperature.
