Definitions

  • the invention relates to a heated spray system, and more particularly to a heated spray system for applying tanning solution to a human body.
  • Tanned skin is generally considered physically attractive. Tanning due to exposure to sunlight, however, causes undesirable skin damage, including sunburn, premature aging of the skin, and even increased risk of skin cancer.
  • "sunless" tanning systems involving the application of a variety of topical skin tanning solutions have gained in popularity. These systems have the benefit of producing the appearance of tanned skin without exposure to potentially harmful ultraviolet light sources. Most systems involve the use of a compound containing the color additive dihydroxyacetone (DHA) to the skin, typically via a hand-applied lotion or cream or through spray nozzle systems.
  • DHA dihydroxyacetone
  • Spray systems for dispensing tanning solution typically use air compressors and air-atomizing nozzles to form a fine mist of the tanning solution which can be sprayed onto the skin. Spray systems are faster and produce a more uniform coating that hand-applied lotions, however they do suffer from some disadvantages. Because the DHA-containing tanning solution is typically kept at room temperature, the spray application of a fine mist of the solution is often uncomfortably cold to the person being sprayed. Also, the solution takes several minutes to dry, and during the drying period tends to feel cold and sticky.
  • An object of the invention is to provide an improved method and apparatus for applying tanning solutions to a human body.
  • Preferred embodiments of the present invention provide a spray gun that heats the air used to propel the tanning solution, rather than the tanning solution itself, in order to make the application of the tanning solution much more comfortable.
  • Other preferred embodiments heat the tanning solution immediately before it is applied to minimize degradation of the active ingredient in the tanning solution that results from temperatures above 40° C.
  • FIG. 1 shows a spray gun according to a preferred embodiment of the present invention
  • FIG. 2A shows another embodiment of a heating assembly that can be used in a preferred embodiment of the present invention
  • FIG. 2B shows an exploded view of the heating assembly of FIG. 2A
  • FIG. 3 shows an exploded view of a spray gun according to a preferred embodiment of the present invention using the heating assembly of FIG. 2A;
  • FIG. 4A shows the spray assembly of the spray gun of FIG. 3 ;
  • FIG. 4B shows an exploded view of the spray assembly of FIG. 4A
  • FIG. 5 A shows a side view of the fully assembled spray gun of FIG. 3
  • FIG. 5B shows a front view of the fully assembled spray gun of FIG. 3;
  • FIG. 5C shows a top down view of the fully assembled spray gun of FIG. 3;
  • FIG. 6 shows another preferred embodiment of the present invention.
  • tanning solutions or sunless tanning solutions will be understood as meaning all substances or mixtures which are able to tan or darken the color of human skin.
  • Most tanning solutions in use today contain 1,3- dihydroxyacetone (DHA) as an active ingredient. DHA, when applied topically to the skin, produces a skin browning effect that is similar in coloration to the tan produced by exposure to UV rays.
  • DHA 1,3- dihydroxyacetone
  • an airbrush-type spray gun is used for applying DHA-containing sunless tanning solutions.
  • the most common type of spray gun used is known as a high volume low pressure (HVLP) spray gun, which uses a relatively high volume of air at a lower pressure than conventional high pressure air guns commonly used, for example, to apply paints or sealants.
  • HVLP high volume low pressure
  • the air pressure at the nozzle is kept to less than 10 psi but the spray nozzle is designed to increase the volume of air directed at the fluid spray.
  • HVLP systems usually make use of a turbine instead of an air compressor, but the present invention is not limited to turbine systems.
  • Most spray guns used for tanning solution application are bleeder-type guns in which the compressed air is continually moving through the gun with only the DHA solution spray turned on and off with the trigger, although other types of suitable air gun systems could be used.
  • the DHA-containing tanning solution is typically kept at room temperature, the spray application of a fine mist of the solution is often uncomfortably cold to the person being sprayed. Also, the solution takes several minutes to dry, and during the drying period tends to feel cold and sticky. The person being sprayed must essentially stand in place waiting for the solution to dry before getting dressed, which adds to the discomfort and also undesirably lengthens the total time required to receive a spray tan.
  • Heating the solution itself would certainly improve the comfort level for anyone being sprayed with the tanning solution, but DHA is sensitive to high temperatures and begins to degrade at temperatures above 40° C. Applicant has determined that heating the solution itself to temperatures below 40° C still results in a spray that it uncomfortably cold for most people. Applicant has also discovered, however, that it is not necessary to heat the solution itself above 40° C as long as the air used to propel the atomized solution is heated to a comfortable level.
  • FIG. 1 shows a spray gun according to a preferred embodiment of the present invention that heats the air used to propel the tanning solution in order to make the application of the tanning solution much more comfortable.
  • the spray gun 100 of FIG. 1 operates in generally the same fashion as a prior art HVLC spray gun, although the present invention is not limited to HVLC spray guns and virtually any type of prior art spray gun could be used as long as the spray pressure is sufficiently low to use in applying solution to the human body.
  • Spray gun 100 makes use of a source of compressed or pressurized air such as turbine 103 and a reservoir of a tanning solution (in cup 104) to spray the solution through a spray tip 106.

  • the gun body 114 also preferably includes a handle 116 for gripping and holding the gun during operation.
  • the compressed air passes through an upper air channel 102 where it flows out spray tip 106, which includes an air cap 130 held in place by air cap ring 132.

  • compressed air flows past the needle valve orifice at the top of the pick-up tube, it creates a partial vacuum in the pick-up tube.
  • An air return in the top of the solution cup allows atmospheric pressure to push the tanning solution up through the pick-up tube.
  • pressurized air can be forced through a discharge passage 128 and into the solution cup 104 to help push the tanning solution up through the pick-up tube 118.
  • the compressed air flowing through upper air channel 102 atomizes the solution and forces the atomized solution through air cap 130 which shapes the solution into a spray pattern.
  • the heated spray gun of FIG. 1 provides a heating assembly 140, which is housed within a heating manifold cover 141 that surrounds the upper air channel 102.
  • Heating assembly 140 also includes heating element 142, which comprises heating coils 144, to raise the temperature of the air passing through the upper air channel so that the air exiting through the air cap has a temperature of approximately 60° C to 95° C.
  • Heating coils 144 are preferably controlled and adjusted via electrical connections 146 and a variable resistor or rheostat (not shown) so that the temperature of the air flowing from the spray gun has the desired temperature.
  • the tanning solution itself is not heated.
  • the pressurized air flowing through the discharge passage and into the solution cup has been warmed by the heating assembly, but does not heat the tanning solution to any significant degree.
  • a siphon-feed can be used to provide a return of room temperature air.

Abstract

L'invention concerne un procédé et un appareil améliorés destinés à appliquer des solutions bronzantes à corps humain. Des modes de réalisation préférés de la présente invention concernent un pistolet de pulvérisation qui chauffe l'air utilisé pour propulser la solution bronzante, plutôt que la solution bronzante elle-même, afin de rendre l'application de la solution bronzante beaucoup plus confortable. D'autres modes de réalisation préférés chauffent la solution bronzante immédiatement avant qu'elle soit appliquée pour minimiser la dégradation de l'ingrédient actif de la solution bronzante qui résulte de températures supérieures à 40°C.
