ABSTRACT:
A device for heating lather dispensed from an aerosol can comprises a housing enclosing a heat sink having lather directing channels establishing fluid flow communication between an entrance orifice adapted to receive the outlet nozzle of the can and an exit orifice for delivering heated lather. The heat sink is heated by a thermostatically controlled electric heating element and a male connector on the housing closely adjacent the inlet orifice allows the device to be plugged into an electrical receptacle for heating the heat sink to a predetermined temperature prior to use. The heat sink has a thermal capacity to heat at least three grams of lather foam to a temperature of about 120.degree.-140.degree. F. after being plugged in for approximately one minute. As a safety feature, the heating device must be disconnected from the receptacle prior to attachment to the aerosol can, since the entrance orifice is physically located on the same exterior housing surface as the male connector and in such proximate position relative thereto as to prohibit simultaneous connection of the male plug to an electrical receptacle and the nozzle of the can to the entrance orifice.
