Definitions

  • the present invention relates in general'to devices for preparing and dispensing aerosol lathers 1n heated c ondition. More particularly, this invention relates to improved devices which are capable of heating such lathers with high efficiency.
  • pressurized aerosol products such as shaving cream lathers, shampoo lathe'rs., 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 liqueiield 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 for heating a long tube through which the lather product passes after release from the aerosol container. Such use of electrical heating means introduces the hazards and inconvenience of fires and electric cords.
  • Such proposed device comprises a cylindrical heat-conductive chamber of sheet metal projecting in exposed position from a standard aerosol-type container and containing therein a supply of heat-conductive material, such as steel wool.
  • the proposed mode of operation involves heating the cylindrical chamber, and any liquid lather-forming material contained therein, by holding said chamber in contact with hot water and thereafter discharging the heated liquid as a warm lather.
  • the proposed device solves to a certain extent one of the prior art problems, namely the necessity of heating rather large volumes of lather after extrusion, by heating instead the relatively smaller volume of corresponding liquid prior to extrusion.
  • a number of shortcomings which shall hereinafter become apparent in the light of the instant invention, are inherent to the proposed device.
  • the present invention relates to a device for preparing and dispensing heated aerosol foams from an aerosol-type container provided with anoutlet member and containing therein a mixture of an aqueous soap solution and a liquefied normally-gaseous propellant, said device comprising a heat-conductive chamber having an inlet member interconnected with the outlet member of said container; means mounted within said chamber for preventing uid flow from said chamber to said container; an outlet member having a manually-operated discharge valve for dispensing the contents for use; and heating means on said heat-conductive chamber for heating the contents thereof.
  • An essential feature of the device of .the present invention is the introduction of means within the heat-conductive chamber for preventing fluid flow from said chamber to the container. Such means serve to prevent .the return of any portion of the liquid soap solution, upon its expansion due to heating, from the heat-conductive chamber to the container.
  • This back-flow which is inherent lto previously-proposed devices which operate by heating the soap solution in its liquid form, and its undesirable effects, will be discussed in detail in conjuncti-on with lthe description of the devices of the present invention.
  • 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. 1B is a sectional view taken along the li-ne 1B-1B of FIG. 1.
  • yFIG. 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 suitable attached bottom, not shown in the drawing, and lid 11. Lid 11 is provided with a container outlet member consisting ⁇ of a central opening for discharge of product, said opening being provided with manuallyoperated valve means.
  • 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 ⁇ tit coaxially with the opening in lid 11, is removed prior yto mounting Athe 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 exof stiffness, lightness and low rate of heat conduction,
  • 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 ange 17 provided with an internal annular channel 18 to iirmly engage the upper rim 19 of the package with a friction snap-tit.
  • 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 iit through the tubular opening deiined 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 saidopen position as long as the heating device is mounted on the aerosol package.
  • a centrally located cylindrical body 23 Fixedly mounted within body 16 and extending upwardly into the cup defined by said body is a centrally located cylindrical body 23 having tubular arms 24 and 25 extending radially therefrom and forming an integral part thereof. -For optimum eiiciency, said tubular arms are positioned on cylindrical body 23 at points substantially removed from each other.
  • a ⁇ heat-conductive chamber is provided for holding the desired amount of liquid soap solution.
  • the heatconductive chamber is defined by a radiator consisting of two closely spaced upright cylindrical plates 26 and 27,
  • the top and bottom edges of cylindrical metal plates 26 and 27 are sealed to one another by conventional means to provide a pressure-tight upright -chamber 28 of annular cross-section.
  • the radiator is formed from a heat-conduc-tive material, preferably metal, and is constructed as to be capable of withstanding pressures in the range of up to p.s.i. which are generated during operation of the present device, which operation will be explained in detail hereinafter.
  • the radiator is connectively sealed to tubular arm 24 and the chamber thereof is interconnected with the container outlet member by means of a chamber inlet member comprising passageway 29, which extends Ithrough tubular arm 24 and cylindrical body 23, and passageway 21, which extends through valve actuator 20 and is interconnected with said passageway 29.
  • a chamber inlet member comprising passageway 29, which extends Ithrough tubular arm 24 and cylindrical body 23, and passageway 21, which extends through valve actuator 20 and is interconnected with said passageway 29.
  • check valve 30 Located in passageway 29 is check valve 30, positioned so as to allow the liquid soap solution to flow from the container through passageway 29 and into chamber 28 but as to prevent any uid from returning from chamber 28 to the container.
  • Such backflow which would occur because of gravity iiow and of the pressure dilferential which develops between chamber 28 and the interior of container 10 when the chamber is heated, is hereby prevented.
  • the radiator has outlet conduit means connectively sealed to tubular arm 25.
  • Passageway 31 extends through tubular arm 25 and interconnects chamber 28 with valve chamber 32. Such embodiment is best shown in FIG. 1B.
  • diaphragm 34 Located on Valve chamber 32 and secured to cylindrical body 23 by crimping .the outer edges of the closure member 33 over a bead which surrounds the valve chamber opening in the top of body 23, is diaphragm 34. Said diaphragm, which includes a plurality of openings 35 which are normally closed by the depending tubular portion 36 of closure member 33, is similar in construction and in mode of operation to diaphragm 12 hereinefore described.
  • valve actuator assembly 36 comprising valve button 37, dispensing spout 38 and tubular valve actuator 39.
  • valve button 37 When the user manually depresses valve button 37, tubular valve actuator is displaced downwardly into actuating contact with diaphragm 34. Any pressurized product present in chamber 28 is thus discharged from said chamber through openings 35 and then through a chamber outlet member, i.e., through longitudinal groove 40 and thence to the atmosphere through passageway 41 in dispensing spout 38.
  • the illustrated heating device also comprises an annular top portion 42 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 4the upper rim 19 of the container.
  • Tubular valve actuator 20 comes into actuating contact with diaphragm 12, allowing the pressurized contents of the vpackage to iiow through openings 14 and to till chamber 28.
  • the hot water submerges the radiator, heating the radiator walls to substantially the temperature of the water itself.
  • 4the liquid soap solution which is present in chamber 28 is similarly heated by heat conduction 'through said radiator walls.
  • such upward surge of the cold soap solution from container 10 into chamber 28 is facilitated by providing, in said.
  • an inert substantially water-insoluble gas which, due to its physical properties, will exist in the gaseous state under the conditions prevailing in said container. It has been found that the use of such gas which, due to its insolubility in the aqueous soap solution and to its ability to remain in the gaseous phase,'makes it possible to lill chamber 28 to its maximum capacity with liquid soap solution, as explained hereinafter.
  • Such gas which is preferably nitrogen but which can be any inert gas substantially insoluble in the aqueous soap solution and substantially non-liqueliable under the conditions prevailing in the aerosol container, such as air, oxygen, and the like, is preferably used in an amount sutiicient to provide a gaseous phase in said container in which the inert substantially water-insoluble gas has a partial pressure of from about 10 to about 50 p.s.i.g. at 70 F.
