Definitions

  • the propellant exists within the can in liquefied form emulsified in the product as small droplets as disclosed, for example, in the US. Patent No. 2,655,480 to Spitzer, Reich and Fine.
  • the liquid droplets of propellant expand to gas bubbles to generate the foam.
  • the nature of the mechanism therefore, includes expansion and frequently an evaporation of the propellant with a cooling effect upon the product.
  • the discharged product is never higher than room temperature and frequently is cooled below room temperature.
  • a shaving cream product for example, it is wellknown that the ease and effectiveness of shaving the human beard is facilitated and advanced by a warm lather.
  • the hairs of the beard are more easily shaved when softened by penetration of moisture from the lather, and the rate and thoroughness of such softening and penetration increases with increasing lather temperature.
  • warm shaving lathers are more comfortable on the face of many users and conform to the feel produced by the conventional practice of producing lather with a brush and warm water.
  • a number of devices have been proposed for heating foam products upon emergence from pressurized aerosoltype containers, including devices for heating pressurized shaving creams.
  • the gas bubbles in extruded foams and lathers act as heat insulators. Consequently, foams and lathers are intrinsically difiicult to heat.
  • the heating devices themselves create an additional and complicating problem because they offer flow resistance to the pressure-propelled, expanding lather.
  • a low flow resistance is a matter of importance because of the properties of many aerosol foams and lathers. They have a high viscosity. Therefore, they cannot be forced through the heat transfer passage of the device at a useful rate unless the passage offers little resistance to flow. Further, many lathers and foams are highly com pressible. They will be compressed as they are forced through the device. After the user discontinues the operation, the compressed foam or lather in the device will expand and ooze out of the exit causing wasteful and messy afterflow. If the heating device Ofiers considerable flow resistance, the lather will be able to expand and escape only slowly thereby causing the afterflow to be prolonged and copious.
  • Some of the proposed devices utilize electric elements for heating a long tube through which the product passes.
  • this collection process may result in a cooling or coarsening of the lather. Also, a substantial volume of product is held within the device after the user discontinues the operation. This lather or foam deteriorates on standing until the device is used again and, accordingly, it is wasted.
  • the present invention obviates such dimculties. It provides a heating attachment for conventional pressurized aerosol-type foam and lather containers which has high efiiciency. It quickly heats the product to a temperature substantially above room temperature while maintaining the discharge at adequate flow rates. It is compact and rugged. it is inexpensive to manufacture. it utilizes heat obtained from the water of an ordinary hot water tap but does not require continuous holding of the device in the stream thereof or connection of a jacket to the hot water tap by tubing or other physical means. It raises the temperature of the pressurized product, as the product emerges from the container, to temperatures close to the temperature of the hot Water. Moreover, it has only a nominal holdup volume of residual product and, therefore, substantially eliminates wastage.
  • the objects of the invention are to provide lather heating means having the advantages and virtue just described.
  • two heat conductive members that form a thin wide chamber are first pre-heated. Next, the foam product is discharged from the package. The product is then formed into a thin wide sheet and heated by passing it through the chamber. Finally, the product is discharged from the chamber.

And outlet means are provided for discharging the form product from the body and from the forming and confining means.
  • the forming and confining means include at least one pair of spaced plates having a length and width substantially greater than the distance therebetween.
  • means are provided for detachably connecting the heating device to the package in such a Way that it can be removed and used with a new package as desired.
  • the heating device may be formed as an integral part of the package.
  • the forming and confining means consist of a radiator mounted within the body spaced from the bottom and side walls thereof.
  • the radiator includes at least one chamber comprised of a pair of closely spaced plates for forming and confining the product as a thin sheet.

Consequently, the body 12 is constructed with a continuous liquid tight bottom Without the cylinder 21, without the valve actuator housing 14, and without the structure associated therewith.
  • a bow shaped clip 52 may be fixed to the body to extend sidewise to grip the can of the aerosol package and hold the heating device firmly at the side of the package.
  • the body 12 may be fitted with an upper cap portion 12A as with the embodiment shown in FIGURES l5A.
  • a spout 32 is provided for the same purpose as with the embodiment shown in FIGURES l-SA.
  • the two cylinder members 36 and 3'7 of the thin sheet forming and confining means need not be exactly parallel to each other. It is import ant, however, that they be closely spaced to each other with the distance between them much less than their diameter or length so that the foam or lather is formed into a thin wide shee And it is important, also, that the size of the plates and the positions of the conduits provide '7 r a relatively short path for the lather to travel between the inlet conduit means and the outlet conduit means.
  • the radiator 34 in the form of hollow cylinder members.

  • the means for forming and confining the product as a thin sheet need not have any specific shape to obtain the advantages of the invention, -i.e., effective foam and lather heating at an adequate flow rate with negligible afterflow and wastage.
  • the heating device of the invention need not be a separate device for removable attachment to the foam dispensing package but may be made as a permanent integral par-t thereof.
  • Heating efiiciency may be defined as the number of degrees by which the lather is heated divided by the difference between temperature of the hot water and the temperature of the unheated lather, expressed as a percentage. The maximum efficiency would be 100%.
  • Holdup volume may be defined as the volume of the residual lather remaining in the heater after use. This equals the chamber volume.
  • Afterfiow may be defined as the amount of lather which continues to emerge from the heater outlet for an undesirable period of time after the valve had been closed. For purposes of standard comparison, three seconds may be selected as a practical length of time during which afterflow would be little noticed.
  • afterliow may be measured by wiping the spout clean three seconds after the valve is closed and then recording the volume of lather and the length of time during which additional lather emerges.
  • Flow 8 rate may be defined as the volume of lather per second passed through the device during operation.
  • the efficiency of heating decreases with increasing rate of lather flow and increases with increasing radiator chamber surface area in accordance with the following equation:
  • E heat efiiciency
  • A plate heat transfer area in square inches
  • R rate of lather flow in cubic centimeters per second. This equation is only approximate, since the exact heating efficiency also varies with other factors.
  • radiator surface areas in the range of 6 to 30 square inches.
  • Surface areas above 6 square inches result in good heating efiiciency at practical lather flow rates and surface areas under 30 inches result in low holdup volume with nominal wastage of lather.
  • the flow path of the sheet of lather through the chamber should be relatively short to avoid pressure which builds up within the chamber. Excessive compression of the thin wide sheet of lather in the chamber causes afterflow. However, it should be noted that with larger chamber widths there is less back pressure within the thin sheet of lather.
  • the practice of the invention will be found useful with embodiments having a flow path from chamber inlet conduit to outlet conduit less than eight inches and most preferably less than about four inches.
