Abstract

A non-metallic housing is provided with an inlet adapted to be coupled with the discharge valve stem of an aerosol type lather container. The inlet communicates with a heating chamber within the housing formed by two concentric aluminum tubes contained within a sleeve formed on the inside of the housing. The tubes are heated by a heat storing electric resistance heating element located within the inner tube. Blade conductors are embedded in and extend from the outside wall of the housing for connection with a conventional wall electric outlet. The blades are connected with the heating element through a circuit which includes a timing switch which limits the time interval during which the heating element is energized. Once energized and raised to operating temperature, the unit is removed from the wall outlet, placed on the valve stem of the container to depress same, whereupon lather flows in through the inlet, through the chamber and a baffled steam trap, and is dispensed through an outlet formed in the housing. A check valve in the inlet passageway prevents reverse flow at times when the valve stem is not engaged. The timing switch comprises a blade thermostat remote from the heating element and a resistor in heat transfer relationship with the thermostat.

Claims

1. Apparatus for heating and dispensing material from an aerosol type container having a projecting valve stem for discharge of the material from the container, said apparatus comprising

a closed non-metallic housing provided with an integral internal tubular sleeve projecting from one inside wall, said sleeve terminating at the wall end thereof in a discharge opening to the exterior of the housing,

means defining a heating chamber within said sleeve, said chamber including an annular portion having concentric inner and outer walls composed of material of high heat conductivity, said chamber communicating with said discharge opening,

means defining a flow passageway through the wall of said housing and sleeve into said annular portion of said chamber for conducting material from said stem to said chamber, said flow passageway including a lateral opening through said sleeve, an annular space between the interior of the sleeve and the exterior of said outer wall of the heating chamber, and a lateral opening in the outer wall of the heating chamber,

a heat storing electric resistance heating element located within said inner wall of said chamber for heating said chamber,

and electric circuit means within the housing and connected with said heating element, said circuit means including connector members having portions extending externally of the housing for connection with an electric outlet.

2. Apparatus as in claim 1,

said heating chamber having an outlet opening spaced from said discharge opening, and

means for deflecting material emanating from said opening laterally and prior to its arrival at said discharge opening.

3. Apparatus as in claim 2, including

a trap and mixing chamber between said deflecting means and said discharge opening.

4. Apparatus as in claim 1 wherein

said electric circuit means includes a resettable timing switch remote from said heating element and chamber, and operable to open a cicuit to said heating element following the elapse of a predetermined time interval after the commencement of energization of the element.
