Patent ID: 8344290

Claim:
A spray bottle heating assembly comprising in operative combination: a) a double-walled spray bottle assembly comprising an inner container defining a reservoir for fluid to be heated, said inner container being disposed within and spaced from an outer shell and having a transverse bottom wall, said outer shell and said inner container having generally the same configuration to provide an insulating space therebetween, said spray bottle assembly including an elongated upward extending neck of size configured to be easily handled by a user, a manual trigger-type sprayer removably securable to the top of said neck and having a dip tube extending down into said reservoir, said outer shell extending down below said transverse bottom wall of said reservoir and terminating in a transverse bottom wall to define a housing for a heater assembly between said transverse bottom walls of said outer shell and said reservoir; b) a heater assembly disposed in said housing comprising a heating element disposed in said transverse bottom wall of said inner container to provide heat to said fluid in said reservoir, an electrical contact assembly disposed in said transverse bottom wall of said housing, and including thermostatic control and temperature indicator circuitry; c) a vapor and water condensate tube disposed in the insulating space between said outer shell and said reservoir connected to an aperture at the upper end of the neck of said reservoir and extending to said transverse bottom wall of said outer shell, said condensate tube including a check valve assembly permitting drainage of condensate from said condensate tube when actuated; d) a base assembly having a transverse top recess for receivingly engaging said transverse bottom wall of said outer shell of said spray bottle, said transverse top recess includes a member for actuating said check valve so that said condensate drains from said condensate tube only when said spray bottle assembly is placed onto said transverse top recess, an electrical power supplying member having an ON/OFF switch, said transverse top recess includes an electrical contact assembly that matingly engages said electrical contacts of said heater assembly to provide power to said heater assembly when said electrical contacts are engaged and said electrical power supplying member is switched ON, and said base assembly includes a removable sump member for recovery of condensate fluid drained from said condensate tube.
