1. A heating and dispensing device for use with a pressurized container having a valved discharge means including a reciprocal valve actuator, comprising a housing adapted to enclose at least the top portion of said container, a stepdown transformer having a primary winding and a tubular secondary winding, said tubular secondary winding including an inlet thereto and an outlet therefrom, coupling means cooperatively engaging said transformer and the valve discharge means of said container, said coupling means comprising a discharge block made of electrical insulation material and formed with a first vertical channel having a widemouthed outlet at one end adapted to receive the discharge means of said container, a second vertical channel spaced therefrom and having its lower end connecting with a horizontal passageway in said block which serves as a discharge spout, the inlet end of said tubular secondary being telescoped with said first vertical channel thereby forming a fluidtight connection and the outlet end of said tubular secondary being telescoped with said second vertical channel thereby forming a fluidtight connection, a metallic peg laterally disposed within said discharge block and forming an electrical contact between the inlet end of the tubular secondary and the outlet end thereof to provide a complete circuit with said secondary, a switch in circuit with the primary winding of the transformer, means in circuit with said switch for providing a fluctuating electric current for said transformer and means responsive to downward pressure causing conjoint downward movement of said transformer and of said discharge block for actuating said valve actuator thereby opening the valve in said discharge means whereby the contents of the container will pass into said inlet of the heated tubular secondary of said transformer, though said heated tubular secondary winding and be dispensed from said outlet into the passageway forming said discharge spout and out of the discharge spout at an elevated temperature as a product ready for use.
