Definitions

  • the present invention relates in general to devices for preparing and dispensing aerosol lathers in heated condition. More particularly, this invention relates to simple, practical and economical devices for preparing and dispensing heated aerosol lathers.
  • 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 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 means introduces the hazards of fires and the inconvenience of electric cords.
  • the present invention relates to a device for heating a foam product as the product emerges from the outlet of a pressurized aerosol-type container, comprising:
  • outlet means for discharging the admixture consisting of foam product and hot water from said body.
  • 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 1A1A 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 discharge of product, said opening being provided with manually-operated 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 bottom. customarily, the user manually depresses the valve bottom, 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 cylindrical cup with an open top.
  • cup 16 is fashioned with a configuration generally complementary to the top of the aerosol package and includes a periphery annular flange 17 to loosely engage the upper rim 19 of the package, thus stabilizing the heating device upon mounting on the aerosol package.
  • 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 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.
  • Circular disk 24 is horizontally mounted within bod 16 in close proximity to the bottom thereof and spaced therefrom by annular ridge 26 which extends from the interior side wall of body 16.
  • Chamber 23 which is defined by the bottom of the in terior section of body 16 and by circular disk 24, is interconnected to passageway 21 of tubular valve actuator 20.
  • the spaced means for conducting the foam product from chamber 23 to the upper interior. section of body 16 consists of four substantially parallel passageways 25 extending vertically through circular disk 24.
  • closure and dispensing assembly 27 comprising a horizontally-disposed foam discharge spout 28 having passageway 29 extending therethrough connecting the interior of body 16 with the atmosphere.
  • the user fills the body 16 with a supply of hot water from a hot water faucet, either before or after attaching the heating device to the aerosol package.
  • the device may be filled either through passageway 29 of spout 28 or by removing closure and dispensing assembly 27 and introducing the hot water directly into body 16.
  • the heating device when the heating device is initially attached to the aerosol package, it merely rests on top on said package and that the openings 14 of diaphragm 12, shown open in the drawings, are in a normal closed position.
  • the user presses on the top of closure and dispensing assembly 27, 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, through passageway 21 in valve actuator and thence into chamber 23.
  • the foam As it enters the chamber, the foam is dispersed into four separate streams which flow in parallel through passageways into body 16 where they become intimately admixed with the hot water contained therein. The heated mixture then emerges from spout 28 through passageway 29.
  • 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 offered by prior art devices.
  • the present devices achieve heating of the foam product by mechanical admixture with hot water whereas the prior art teaches heating by bringing the product in heat exchange relationship with a heated surface.
  • the present devices can be constructed wholly from common plastic material having the properties of stiffness, lightness and low cost, such as poly styrene, polyethylene, and the like, and can be very compact in size.
  • a plastic device, 2 inches high and 1 inch in diameter, constructed substantially as illustrated in the drawings was found to give satisfactory results.
  • a device for heating a foam product as the product emerges from the outlet of a pressurized aerosol-type container comprising:
  • outlet means for discharging the admixture consisting of foam product and hot water from said body.
  • a device for heating a foam product as the product emerges from the outlet of a pressurized aerosol-type container comprising:
