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 efficiency.
  • 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 normally gaseous propellant. Such compositions, when released from a valve-controlled aerosol type container yield a stable lather which can be applied directly to the skin of the user prior to shaving. Due to the expansion and evaporation of the liquefied propellant upon extrusion, the temperat-ure of such lather is usually below room temperature and the body temperature of the user. The application of such c-ool 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 means introduces the hazards of fires and the inconvenience of electric cords.
  • 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:
  • the lather In operation, when the lather is extruded from the aerosol container, the lather enters the first chamber and then divides and flows through the passageways of the heat-conductive members, which members have been preheated as hereinafter described.
  • the plurality of streams of hot lather then flow into the second chamber, where they recombine, and thence emerge from the outlet member as a single stream in a heated state.
  • 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 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 includes 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 the 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 in actuating relationship with said button.
  • the user manually depresses the valve button, bringing the tubular valve actuator 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.
  • 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 peripheral annular flange 17 to loosely engage the upper rim 19 of the package, thus stabilizing the heating device upon mounting on the aerosol package.
  • the tubular actuator 20 When the heating device is mounted on the package, the tubular actuator 20 is slidably engaged in 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, is in abutting relationship with diaphragm 12.
  • foam dispersing means 23 and foam combining means 24 Mounted within cup 16 and substantially removed from each other are foam dispersing means 23 and foam combining means 24.
  • Said foam combining means as best shown in FIG. 1A, comprises two substantially circular parallel plates 25 and 26 having a plurality of flanges 27 extending radially therefrom having substantially similar circular depressions on corresponding sides thereof. When said circular parallel plates 25 and 26 are sealed together by conventional means, they define a substantially circular foam combining chamber 28.
  • Foam dispersing means 23 comprises foam dispersing chamber 29 and has substantially the same mechanical configuration as foam combining means 24 described hereinbefore.
  • Foam dispersing means 23 is horizontally mounted within body 16 in contact with or in close proximity to the bottom thereof and in sealing engagement with the upper end of valve actuator 20.
  • Internal passageway 21 of valve actuator 20 is interconnected with the interior of foam dispersing chamber 29 at a substantially central position.
  • Foam combining means 24 is horizontally mounted within the interior of body 16 at a point substantially removed from foam dispersing means 23 and substantially parallel thereto. Flanges 27 of foam combining means 24 rest on annular ridge 30 which extends from the interior side wall of body 16.
  • heat-conductive members 31 Mounted between foam dispersing means 23 and foam combining means 24 are a plurality of heat-conductive members 31 having passageways 32 extending therethrough interconnecting the interiors of foam dispersing chamber 29 and foam combining chamber 28.
  • the heatconductive members are preferably metallic tubes having annular cross-sections. However, such heat-conductive members may be made from nonmetallic materials and have various cross-sectional shapes without departing from the scope of the invention.
  • a product discharge assembly is sealingly mounted on foam combining means 24.
  • Such assembly comprises an actuating button 33, a depending tubular portion 34 and a foam discharge spout 35.
  • An internal passageway 36 extending through tubular portion 34 and spout 35 connects the interior of foam combining chamber 28 with the atmosphere.
  • the illustrated heating device also comprises anannular top portion 37 which is fitted to the top of body 16 and which rests on foam combining means 24.
  • the user places the can with the attached heating device under a hot water faucet and fills the body 16 with a supply of hot water.
  • the hot water enters the body 16 by flowing past foam combining means 24 through the openings defined by flanges 27 and submerges heat conductive members 31, heating the walls of said heat conductive members to substantially the temperature of the water itself.
  • the entire heating unit merely rests on the top of the aerosol package and that the openings 14 of diaphragm 12, shown open in the drawings, are in a normal closed position.
  • the user then removes the can from the faucet and presses actuating button 33, thus depressing the entire heating unit, including valve actuator 20, downwardly as shown in FIG. 1.
  • the propellant within the aerosol package propels the product through dip tube 13, through openings 14 of diaphragm 12, and into first or foam dispersing chamber 29 through the chamber inlet member which consists of passageway 21in valve actuator 20.
  • the foam As it enters the chamber, the foam is dispersed into eight separate streams which flow in parallel through passageways 32 in heat conductive relationship with the inside walls of heat conductive members 31.
  • the heated product then enters foam combining chamber 28, where the eight streams recombine and finally emerge from said second or foam combining chamber 28 through the chamber outlet member consisting of passageway 36 in depending tubular portion 34 and spout 35.
  • Diaphragm 12 due to its resiliency, returns to its normal closed position by displacing valve actuator 20, and thus the entire heating unit, upwardly.
  • the devices of the present invention eliminate many of the disadvantages ofiered by prior art devices.
  • the use of multiple heat conductive members reduces the pressure of the lather during heating. This in turn substantially reduces the mechanical breakdown due to flow resistance offered by the heat conductive members.
  • the present invention permits the use of heat conductive members having a relatively small cross-section, thus facilitating heat transfer and permitting the product to be heated to a temperature close to the hot water temperature. Since such efi'iciencies can be achieved with relatively short residence times, thermal breakdown of the product is also substantially eliminated.
  • the heating effioiency of the apparatus depends on the lather flow rate and on the number and dimensions of the heat conductive members.
  • the total volume inside the heating unit, and hence the amount of lather wasted each time the heater is used, should be as small as feasibly possible.
  • At least 8 heat conductive tubes having an internal diameter of about 0.05 to about 0.2 inch and a length of from about 1 to about 4 inches are used, the number and dimensions of said tubes being selected as to provide a heat transfer area of at least 6 square inches but, at the same time, maintain the total volume content of the entire heating unit at 0.5 cubic inches or less.
  • Heating devices utilizing tubes having dimensions falling Within the above preferred ranges are found to yield optimum heating efficiencies at lather flow rates of about 8 cc. per second or lower.
  • novel devices of the invention can be permanently mounted on the aerosol package by the manufacturer.
  • the heat conductive members of the novel devices can be constructed of a heavy gage material or provided with heating fins. This construction would eliminate the need for the water-holding cup and permit the members to be preheated by merely holding the device under a hot running faucet.
  • 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 comprising:
  • the tubes have an internal diameter of from about 0.02 to about 0.3 inch and a length of from about 0.5 to about 8 inches, and wherein said tubes have a total heat transfer area of at least 4 square inches.
  • At least 8 heat-conductive tubes having an internal diameter of from about 0.05 to about 0.2 inch and a length of from about 1 to about 4 inches, said tubes being mounted within said body and having passageways extending therethrough interconnecting said first chamber with said second chamber.
  • thermoelectric tubes have a total heat transfer area of at least 6 square inches.
