Definitions

  • the present invention relates in general to devices for preparing and dispensing aerosol lathers in heated condition. More particularly, this invention relates to improved devices which are capable of heating such lathers with high efiiciency.
  • pressurized aerosol products such as shaving cream lathers, shampoo lathers, and the like
  • a number of devices which permit the dispensing of such products in a heated condition have been described.
  • Aerosol shaving lathers are usually produced from liquid compositions comprising a mixture of an aqueous soap or detergent solution and a liquefied normallygaseous propellant. Such compositions, when released from a valve-controlled aerosol type container yield a stable lather which can be directly applied to the skin of the user prior to shaving. Due to the cooling effect exerted by the expansion and evaporation of the liquefied propellant the temperature of such lather is usually below room temperature and the body temperature of the user. The application of such cool lather to the body of the user is not entirely pleasant. Furthermore the softening effect of such lather on the beard or hair of the user is reduced by the lower temperature thereof.
  • Some of-the proposed devices utilize electrical means residence time. Furthermore, a substantial volume of lather is left within the tube after the user discontinues the operation. This residual lather, in a compressed state due to the high flow resistance of the device, will expand and ooze out of the tube outlet causing prolonged and copious afterflow.
  • the present invention relates to a device for preparing and dispensing heated aerosol foams from an aerosol-type container provided with an outlet member and containing therein a mixture of an aqueous soap solution and a liquefied normally-gaseous propellant, said device comprising a heat-conductive elongated body portion having a passageway extending therethrough, an inlet means on said passageway adapted for interconnection with said outlet member, an outlet means on said passageway having a manually-operated discharge valve for dispensing the contents therefrom, and heating means on said heat-conductive body portion.
  • the present device permits heating the contents of the aerosol container prior to extrusion while they are still in the liquid form and thus eliminate most of the disadvantages of the prior art devices hereinbefore discussed.
  • FIG. 1 is a side elevational view of a preferred device, partly in longitudinal section;
  • FIG. 1A is a sectional view taken along the line 1A- 1A of FIG. 1.
  • FIG. 1 shows a preferred form of a heating device of the invention removably mounted on a standard aerosol container of a type commercially used by some manufacturers of aerosol products. It is comprised of can 10 having a suitably attached bottom, not shown in the drawing, and lid 11. Lid 11 has a central opening for disfor heating a long tube through which the lather product passes after release from the aerosol container.
  • electrical heating means introduces the hazards and inconvenience of fires and electric cords.
  • the valve means include a diaphragm 12, preferably made of rubber or other resilient material, which is mounted between the lid 11 and the conventional dip tube 13.
  • the diaphragm 12 includes a plurality of openings 14 which are normally closed by the centrally located depending tubular portion 15 of lid 11.
  • a valve actuator assembly not shown in the drawing, which consists of a valve button, a dispensing spout, and a tubular valve actuator extending downwardly from said valve button.
  • the user manually depresses the valve button, displacing the tubular valve actuator downwardly in actuating contact with the diaphragm 12.
  • valve actuator assembly which is customarily mounted with a friction fit coaxially with the opening in lid 11, is removed prior to mounting the heating device of the invention on the aerosol container.
  • valve construction described above is conventional and it will be understood, of course, that other and different forms of valve mechanisms may be employed with the present invention. It will also be understood that the use of such different valve mechanism will necessitate some minor changes in the construction of the novel heating device, but the necessity of such changes and the extent thereof will become apparent to one skilled in the art in the light of the instant specification.
  • the illustrated heating device includes a body 16 capacitated to hold a supply of hot water and having the general configuration of a cup with an open top. It is made of common plastic material having the properties of stiffness, lightness and low rate of heat conduction, such as linear polyethylene, polypropylene, polystyrene, and the like.
  • the bottom of cup 16 is fashioned with a configuration generally complementary to the top of the aerosol package and includes a depending peripheral annular flange 17 provided with an internal annular channel 18 to firmly engage the upper rim 19 of the package with a friction snap-fit.
  • tubular valve actuator 20 Extending downwardly from cup 16 is centrally located tubular valve actuator 20 having an internal passageway 21 extending therethrough.
  • the tubular actuator 20 When the heating device is mounted on the package by exerting downward pressure sufficient to snap annular flange 17 over rim 19, the tubular actuator 20 is similarly displaced downwardly with a friction fit through the tubular opening defined by the depending tubular portion of the lid 11.
  • the lower end of the actuator provided with a diametrically disposed slot 22, engages diaphragm 12, actuating said diaphragm and thereafter maintaining it in the open position, i.e., in the position wherein openings 14 are no longer obstructed by tubular portion 15.
  • Diaphragm 12 remains in said open position as long as the heating device is mounted on the aerosol package. Consequently, once the heating device is mounted on the aerosol package, the pressure inside said heating device is the same as the pressure inside said pressurized aerosol package.
  • Passageway 24 interconnects with passageway 21 of valve actuator whereas passageway interconnects with valve chamber 26.
  • tubular body 27 Mounted within the cup defined by body 16 is coiled tubular body 27 having an internal cylindrical passageway 28 extending therethrough. The ends of tubular body 27 are connectively sealed to cylindrical body 23 as to interconnect the inlet means of passageway 28 with passageway 24 and the outlet means thereof with passageway 25.
  • diaphragm 30 Located on valve chamber 26 and secured to cylindrical body 23 by crimping the outer edges of the closure member 29 over a bead which surrounds the valve chamber opening in the top of body 23, is diaphragm 30.
  • Said diaphragm which includes a plurality of openings 31 which are normally closed by the depending tubular portion 32 of closure member 29, is similar in construction and in mode of operation to diaphragm 12 hereinbefore described.
  • valve actuator assembly 33 comprising valve button 34, dispensing spout 35 and tubular valve actuator 36.
  • valve button 34 When the user manually depresses valve button 34, tubular valve actuator 36 is displaced downwardly into actuating contact with diaphragm 30. The pressurized products can thus be discharged through openings 31,
  • the illustrated heating device also comprises an annular top portion 39 which is fitted to the top of body 16.
  • the user mounts the heater on said container by displacing the unit downwardly as to allow peripheral annular flange 17 to engage the upper rim 19 of the container.
  • Tubular valve actuator 20 comes into actuating contact with diaphragm 12, leaving openings 14 unobstructed.
  • valve chamber 26 The heated product then enters valve chamber 26 through passageway 25 and exits to the atmosphere through openings 31, groove 37 and passageway 38.
  • the heat-conductive body of the present invention has preferably a total volume content not in excess of 5 cubic centimeters and a total heat transfer surface of at least 30 square centimeters.
  • the heat-conductive body of the invention is a metallic tube having a total volume content of from about 3 to about 4 cubic centimeters and a total heat transfer surface of at least 60 square centimeters.
  • thermoelectric elongated body portion has a total heat transfer surface of at least 30 square centimeters and the passageway ex- 5 tending therethrough has a total volume up to 5 cubic centimeters.
  • thermoelectric body portion has a total heat transfer surface of at least 60 square centimeters, and the passageway extending therethrough has a total volume of from about 3 to about 4 cubic centimeters.
