2. Description of Related Art
The prior art discloses a variety of descenting (removal of scents) apparatus and methods, examples of which (and not by way of limitation) are found in U.S. Pat. Nos: 4,309,388; 4,867,052; 4,941,270; 5,087,426; 5,433,919; 5,468,454; 5,484,472; 5,514,345; 5,539,930; 5,547,476; 5,667,564; 5,681,355; 5,762,648; 5,766,560; 5,789,368; 5,790,987; 5,911,957; 5,931,014; 6,007,770; 6,009,559; 6,134,806; 6,134,718; 6,149,038; 6,156,268; 6,163,098; 6,284,204; 6,312,507; 6,355,216; 6,379,435; 6,503,547; 6,564,591; 6,565,805; and 6,576,190, and published U.S. patent application 2003/0044308—all of which are incorporated fully herein for all purposes.
Hunters, wildlife enthusiasts, and wildlife photographers all have an interest in attracting wildlife, such as, but not limited to, deer; and/or an interest in not being detected by animals. Deer rely heavily on their sense of smell to react with their surrounding environment, including to sense danger, interact with other deer and find food. Scents that are not a natural part of the environment will often function as a warning to deer, which may result in the deer being spooked and running from the unnatural scent.
According to Bernier et al in Analytical Chemistry, 2000, volume 72, issue 4, pages 747-756 and references cited therein which are incorporated fully herein by reference, as many as 346 discernible compounds were identified in human skin emanations. The majority of these were carboxylic acids, alcohols and esters, but aldehydes, aromatics, heterocyclics, ketones, sulfides and thio compounds were also identified. Work cited in Bernier has identified over 100 compounds from human breath. Work cited in Bernier identified foot odor as another source of odor. Some of these compounds are the result of bacteria reacting with body emanations, while other compounds directly emanate from humans. Other compounds emanated from humans can include pheromones, deodorants and perfumes as well as the detergents, perfumes, scents, and additives left on human clothes. While it is not known which specific compound or blends of compounds emanating from humans are identified by an animal as human, there is currently no effective way to eliminate or reduce odors from humans and from clothing and equipment enough to reduce the odors to inhibit detection by wildlife or effectively attract wildlife.
Persons interested in preventing detection by deer detecting human odors or interested in attracting deer often use masks, attractants, or cover scents to prevent alerting and spooking the deer. Some commonly used masks are carbon sprays which, in addition to being dangerous to inhale and which can irritate skin, become ineffective once dry. Many of the attractants contain deer urine or estrous, which besides being offensive to the human user, have limited shelf life and are generally ineffective since especially the estrous tend to occur naturally only in certain seasons. Cover scents such as fruit extracts or fragrances last a short time and are often so over-powering that the deer easily identifies the smell as unnatural and runs. The use of descenting soaps and shampoos is messy, time-consuming, often skin irritating, often ineffective and does not address breath odor. Breath descenting using herbs are generally distasteful, and face masks containing carbons or sieves are extremely uncomfortable.
More recently, the use of clothing containing activated carbons and/or clothing containing bacteria killing metals such as silver has gained some popularity. However, activated carbon has a very low capacity for odorants and requires temperatures preferably above 400° C., more preferably above 600° C. to regenerate the carbon. These temperatures are well beyond temperature (100 C to 120 C) that a conventional gas or electric clothes dryer is capable of achieving. Placement of clothing in ovens capable of achieving 400 C plus temperatures needed to regenerate the carbon can damage the fabric of a garment. Silver or other metal-containing clothing requires direct contact of the metal with the bacteria to be effective, which is almost never the case since the clothing would then be so restricting as to be uncomfortable. These types of clothing are also expensive and do not address human odors such as those in human breath, nor do they address any of the odors emanating from the foot or any exposed part of the skin like the head and hands.
It has now been discovered that gaseous ozone effectively kills bacteria and reduces or eliminates odors emanating from humans as well as odors contained in clothing worn by hunters. The advantages of ozone over other known masking and descenting methods include the facts that: ozone is a gas that eliminates odors emanating from a person (e.g., a hunter) and from personal equipment and can eliminate odors in a space between a person and an animal; and ozone is completely natural to the environment and leaves behind a very pleasant clean smell that wildlife and humans readily recognize, e.g., after a lightning rain. Known ozone generators include electrical discharge, UV light, and combinations thereof. The generator may be battery operated, operated with a car adaptor, and/or may be operated with AC current. The AC current may be supplied directly from an electrical outlet, or may be supplied using a portable generator.
Ozone is well known to treat odorous air, microorganisms, bacteria, mold, smoke, aromatic hydrocarbons, and volatile organic compounds (see for example U.S. Pat. Nos. 1,961,878; 2,203,188; 3,421,836; 3,750,556; 3,937,967; 3,949,056; 4,045,316; 4,863,687; 4,904,289; 4,990,311; 5,087,426; 5,835,840; 5,983,834; 6,094,549; 6,613,277; 6,632,407; 20020030022; 20060096331; and references cited therein, which are all of which are incorporated fully herein for all purposes); and foreign references EP 261987; WO 200151096; WO 2003089017; WO 2005021135. WO 2005077425 and references cited therein, which are incorporated fully herein for all purposes, teaches the use of ozone to descent hunters clothing and other personal effects to be worn or carried on a hunting trip. In this case, the hunter, the clothing or personal effects are placed in a container, a portable enclosure, or a special descenting closet or room located, e.g., in a lodge or cabin in which the hunter is staying. As soon as the hunter leaves the building and enters a vehicle, or passes a moving vehicle, or begins to sweat, any prior descenting is of little value.
Animals have an acute sense of smell and are capable of recognizing a human scent or any other scent that is not advantageous in that environment at long distances. To avoid such recognition a hunter will attempt to stay down wind of the animal being hunted. Certain known methods used by hunters to trick animals are to mask the human odor utilizing a carbon spray or cover spray scents or an animal scent. Unfortunately the animal scents which are utilized, are obnoxious and linger on the clothing for long periods of time and often do not mask out human scents. Some of the scents utilized include animal urine. A hunter who is camping overnight does not desire the animal scents to be carried over to bedtime, home, car, etc.
There are other drawbacks in utilizing animal scents or any other scents. The scent may attract a predator of the game which the hunter is not hunting for which the hunter may not be prepared to encounter. Containers containing food, beverages, or any other substance emit scents readily recognizable to animals that may not be masked by animal scents or may not be natural to a given environment. Female hikers, campers, hunters, etc. can emit a readily recognizable scent to animals from menstruation that may not be masked by animal scents. Also, the weapon used by the hunter has an odor recognizable by some animals which cannot be disguised with a scent.
Fishermen have the problem of fish odor on their hands and clothes which is difficult to remove. For fishermen camping overnight the fish odor is not only undesirable because of the odor but can also attract animals such as bears which the fishermen is not prepared to meet.
Hunters have prepared their clothing before hand by washing to remove prior scents and/or human odor. The washing materials may also leave an odor. However, out in the field the hunter can sweat and permeate the clothing with a human scent. It would be desirable to deodorize clothing during a hunt or while on a fishing trip.
Ozone has been used for decontaminating buildings and for decolorizing denim garments. U.S. Pat. No. 5,833,740 to Brais discloses an apparatus for sterilizing bottles utilizing ozone. The reference recognizes that ozone in large quantities can be harmful or irritating. Consequently, it was necessary to provide means for decomposing the excess ozone and/or to cause its escape into the atmosphere.
Ozone is a powerful oxidizing agent. Ozone has 150% of the oxidizing potential of chlorine and twice the oxidizing potential of bromine. Ozone has been shown to be much more effective than chlorine with a reaction time up to 10 times faster. Ozone also readily self-destructs into simple diatomic oxygen due to its inherent instability. Ozone oxidizes biological products and kills bacteria.
Catalytic ionization of air using ultraviolet light is known to produce a mixture of ozone-containing hydroxyl and hydroperoxide ions. Ionization devices which are used to eliminate smoke and odors are known in the art to produce hydroxyl and hydroperoxide ions, e.g., those used in automobiles.

BRIEF SUMMARY OF THE INVENTION

The present invention, in certain aspects, is directed to systems and methods which use gaseous ozone to kill bacteria and reduce or eliminate odors emanating from humans, e.g., in breath or from skin, as well as odors in clothing worn by a person that are volatilized into the air space between the human and the wildlife to prevent wildlife from detecting the presence of humans and/or to enhance encounters with and the attraction of wildlife. One embodiment is directed to wearing or carrying a portable ozone generator while walking, waiting for, or engaging in attracting wildlife. Another embodiment is directed to wearing or carrying a portable ozone generator while engaging in an activity, e.g., walking, waiting for wildlife, or engaging in preventing wildlife from detecting the presence of humans. Another embodiment is directed to clothing incorporating or combined with ozone directing apparatus or devices. Yet another embodiment is directed to the treatment of clothing—e.g., directly with ozone, prior to or while being worn—to enhance the attraction of wildlife. Yet another embodiment is directed to the use of gaseous ozone in or around a tent, site, or blind to reduce or eliminate odors to enhance the attraction of wildlife, e.g., for hunters, wildlife enthusiasts and wildlife photographers. Yet another embodiment is directed to the use of gaseous ozone in or around a tent, site, or blind to reduce or eliminate odors to prevent the detection of humans by wildlife, e.g., for hunters, wildlife enthusiasts, and wildlife photographers.
The invention relates to a method for deodorizing the clothing and apparatus of sportsmen, professional or non professional. More particularly, there are provided methods for reducing or eliminating human scent or any other foreign scent from clothing etc.; and there are provided methods for removing human scent or any other foreign scent (collectively “foreign scents”) from items and/or clothing, e.g., clothing used by hunters before or during a hunt—through the use of ozone or hydroxyl and hydroperoxide ions produced by ionization in a manner that would not cause irritation or injury to the user or equipment. Also, there is provided a method for removing fish odor from fishermen and their clothing and equipment while in the field including lures, tackle boxes and containers. The principal objective of the invention is the provision of a method for effectively removing human scent from clothing used by sportsmen.
It is yet another object of the invention to provide a method for military personnel to escape detection by other humans or by scent animals (e.g., scent dogs). In certain particular aspects the present invention provides methods for reducing or eliminating human or any other foreign scent from items, e.g., from clothing and equipment, used by military personnel desiring to evade detection or capture—through the use of ozone or ozone with hydroxyl and hydroperoxide ions produced by ionization in a manner that would not cause irritation or injury to the user or equipment.
It is another object of the invention to deodorize fish odor on fishermen.
It is yet another object of the invention to descent or deodorize sportsmen while out in the field by the use of ozone or hydroxyl and hydroperoxide ions.
Yet another object of the invention is to provide a method of deodorizing clothing with ozone so that it will not cause irritation or harm.
It is a further object of the invention to provide ozone in a compressed or generated form in a hand held container for application in the field by sportsmen.
Other objects and advantages of this invention will become apparent from the description of the preferred embodiments and the claims.
For safety reasons, government regulations have recommended, and sometimes regulated, the amount of ozone to which a human is to be exposed. For example, OSHA requires that employee permissible exposure limit (PEL) as an eight hour time-weighted average value of 0.1 ppm ozone in air. The OSHA short term exposure limit (STEL) is 0.3 ppm over a 15 minute period, not to be repeated more than two times in an eight hour period. Prolonged exposure of humans has produced no apparent ill effects at 0.2 ppm. In a variety of embodiments of the present invention, a human being is exposed to ozone generated by an ozone generator. In any such embodiments the human being may be limited to exposure to ozone in a concentration of 0.2 parts per million (or less). In any such embodiment, in certain aspects, in which the human being is to be exposed to ozone for a time period of up to about 8 hours (about 8 hours or less), the ozone concentration is limited to 0.1 parts per million (or less). In any such embodiment, a desired level of ozone concentration to which the human being is exposed is maintained in a space of a desired size around the human being, e.g., in certain aspects, a desired level of ozone is maintained within about a 6 foot radius of the human being (and, in one aspect, at an ozone concentration level of 0.2 ppm or less and, in another aspect, at an ozone concentration of 0.1 ppm or less).
In certain embodiments according to the present invention, clothing is treated with ozone so that ozone is retained on the clothing, e.g., for several hours and, in certain aspects, for up to 24 hours, and in other embodiments for more than 24 hours. Ozone retained on the clothing continues to descent scents which come in contact with the ozone. A variety of cloths, including, but not limited to knits, fleeces, cotton cloth, cotton blended cloth, fibrous cloth, and rough cloths have retained ozone. In other embodiments treatment with ozone temporarily changes the color of colored cloth and then, after some time period, the cloth returns to its original color. This color change indicates that an item of clothing has been treated with ozone; that it is retaining some ozone thereon; and the change back to an original color indicates ozone is no longer being retained on the clothing. “Color” refers to any color (e.g., but not limited to, white, red, green, blue, yellow, orange, violet, black, purple, brown, etc.)
Accordingly, the present invention includes features and advantages which are believed to enable it to advance descenting technology. Characteristics and advantages of the present invention described above and additional features and benefits will be readily apparent to those skilled in the art upon consideration of the following detailed description of preferred embodiments and referring to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

“Person” as used herein includes, but is not limited to, “hunter” and a “hunter” is defined as including hunters of wild game and other animals and also includes nature enthusiasts, trappers, military personnel, military personnel seeking to evade others and/or avoid capture, hikers, fishermen and fisherwomen, backpackers, and photographers; and “hunt” or “hunting” is defined as including the hunting of wild game and other animals for the purposes of encountering, attracting, avoiding, escaping from, photographing, avoiding detection by, capturing, killing and/or observing them. “An animal” as used herein includes, but is not limited to, any small or large game animal including deer, elk, sheep, pig, moose, caribou, bird, rabbit, elephant, mountain lions, bear and fish, and combinations thereof and, in certain aspects, “animal” includes human beings. For example, a human may desire to prevent the detection of human body odors or odors resulting from the human consumption of various foods and/or spices (e.g., pepper or curry) and/or beverages by the human himself or herself or by another human. A “blind” as used herein includes any natural or man-made place of observing, hiding and/or protecting a person including, but not limited to, a tent, shack, tree stand, shrubs, cut limbs, rocks, place for protection from natural elements, and combinations thereof.
“Descenting material generators” include generators that produce a material as a gas, a fine mist, a spray with solids, or some combination thereof that is capable of descenting human scents; the materials including, but not limited to, oxidants, ozone, hydroxyl radicals, hydroperoxides, and other known descenting materials; with or without an operating integrated fan. A “mist” produced by an ozonator or descenting material generator is a mist of descenting material and a liquid, e.g., water or organic-solvent material (e.g., alcohols like methanol or ethanol or isopropanol or glycol ether, e.g., ethylene glycol methyl ether and ethylene glycol dimethylether) that is capable of solubilizing descenting material. Ozone generators of all sizes, weights, power sources and types are widely available from sources such as Sharper Image (www.sharperimage.com), Biozone Scientific (www.biozonescientific.com), Ozone Solutions (www.ozoneapplications.com) and Air Zone (www.aaaozone.com). Optionally, the ozone generator contains an additional ion generator source for negative ionization of the air. These type of units are commercially available, e.g., IONIC BREEZE™ products from Sharper Image. Optionally, the ozone generator is of the type that includes atomized water or hydrogen peroxide to produce highly reactive hydroxyl radicals. Such generators are disclosed, e.g., in Japanese patent references JP 11-00948A; JP 11-009949A; JP2003001/237A2; JP 11-226108A; and JP 11-226106A. Optionally, the ozone generator can include the simultaneous or intermittent generation of other known oxidizing agents, bacteria and odor removing substances such as chlorine, zinc ricinoleate and/or cyclodextrine, e.g., as contained in FEBREEZE™ fabric softener. For hunting purposes it is preferable that the unit be light weight, portable, and battery and/or solar power operated and/or with a hand crank generator, e.g., when walking to a hunt. When hunting from a stationary location, such as blind or tent, it is preferable to have the same features, but if a portable generator or source of AC electric power is available, then ozone generators having this capability are also preferred. When hunting from a blind or a tent, it is still preferred to use low weight generators since the generator often needs to be transported, e.g., carried from a lodge, cabin or vehicle, e.g., to a watching or hunting location; but generators weighing up to about 8 lbs. and more may also be used. In general, light weight ozone generators produce lower levels of ozone and generate ozone for a shorter period of time, especially when small batteries such as size A, AA, AAA, C, D and 9 volt batteries are used. However, many battery operated portable ozone generators last eight hours and more on one battery charge. The ozone generation source can be of any type including a UV lamp, electrical discharge, or combination of both. Certain portable, battery-operated and solar-operated ozone generators have UV lamps as the ozone generator source due mainly to the lower voltage required for UV lamps. Larger ozone generators capable of operating on AC current can be UV lamp, electrical discharge or a combination of both. Electrical discharge ozone generators can be capable of generating larger amounts of ozone in a smaller size container, but adding blowers, fans and transformers (which is within the scope of the present invention) can result in some generators being heavier than ozone generators having UV lamps. Small, portable battery and solar operated ozone generators are available which have small fans, though many have no fan at all. One advantage of including at least a small fan is that the ozone can be dispersed over a larger area more readily, but it is not necessary that a fan be included in the ozone generator. For ozonating a larger area like a tent, especially when two or more hunters are occupying the tent, an ozone generator having a fan or fan blower is preferred, but not required. If a fan or fan blower is used, a fan can be used which makes minimum noise, especially beyond about a ten foot radius of fan operation so as not to spook an animal, e.g., a deer.
Certain ozone generators are capable of producing 1 mg and up to 5,000 mg/hr of ozone and more. For safety consideration, in certain embodiments of the present invention a person is exposed to a constant concentration of 0.1 ppm ozone or less and, in one aspect, such a concentration over an 8 hour time period or less; but exposures to larger concentrations up to 0.2 ppm ozone and more over short periods of time can be tolerated by most humans. One preferred ozone generator is one which can maintain about 0.1 ppm or less total ambient concentration of ozone over an area of approximately a six foot radius of a human. In certain aspects the present invention provides methods for reducing foreign scent in a space between a human being and an animal, the methods including generating descenting material with a generator, introducing the descenting material into a space or zone between a human being and an animal, the space or zone containing foreign scent, and reducing the foreign scent in the space or zone with the descenting material. In certain embodiments, the descenting material is ozone and the method further includes: exposing the human being to a time-weighted average value of 0.1 ppm ozone in air or less over an area within a radius of six feet of the human being; exposing the human being to a time-weighted value of 0.2 ppm ozone in air or less; or exposing the human being over a time period of eight hours or less to a time-weighted value of 0.1 ppm ozone in air or less. In other aspects the present invention provides methods for reducing foreign scent in a space or zone between a human being and an animal, the methods including producing descenting material with a generator, with direction apparatus, directing said descenting material in a desired direction into the space or zone, the direction apparatus including at least one director in communication with the generator for receiving produced descenting material from the generator and for directing said descenting material into the space or zone, and reducing the foreign scent in the space or zone with the descenting material. In certain embodiments of such methods the descenting material is ozone and the method further includes: exposing the human being to a time-weighted average value of 0.1 ppm ozone in air or less over an area within a radius of about six feet of the human being; exposing the human being to a time-weighted average value of 0.2 ppm ozone in air or less; or exposing the human being over a time period of eight hours or less to an ozone concentration of a time-weighted average value of 0.1 ppm ozone in air or less. For humans that are pursuing an encounter with an animal in a leisure manner, e.g., those hunting and producing only small amounts of odor via sweat and lighter breathing, a small battery generated ozone generator like the BIOZONE Model 50 Personal Air Purifier capable of operating on four C batteries can be used. For persons engaging in an animal-encounter activity, e.g., photography or hunting, for an extended period, e.g., an hour, two hours, three hours, four hours, or more hours, a larger ozone generator such as the BIOZONE SCIENTIFIC TRAVELAIRE™ generator weighing about 8 oz. or an OMZ-200™ generator from Ozone Solutions weighing about 12 oz. and operating only with larger batteries or AC can be used. For those engaging in mostly stationary activity, e.g., hunting outdoors or in a tent or blind, then an ozone generator such as the OZONE SOLUTIONS Model MZ-450 can be used which is capable of deodorizing 2,000 sq. ft. with it's 450 mg/hr ozone generation and 61 cfm (cubic feet per minute) fan, or a 6 lb. OZONE SOLUTIONS OMZ-3400 having a 3,400 mg ozone output and 34 cfm fan can be used. The MZ-450 and OMZ-3400 are primarily suited for 110V operation, but can be operated with larger batteries e.g., batteries currently weighing about 4 lbs. and capable of operating for four or more hours on a single battery charge. As battery technology improves, it may be possible to operate high ozone concentration generators with batteries that weigh much less.
The use of ozone can quickly reduce or eliminate odors (including human odors), volatiles and contaminates (all collectively referred to as “foreign scents”) on a person or his or her clothing and equipment and in the space between the person and an animal that may be alerting wildlife to the presence of a human. The ozone is cleanly reduced to oxygen. The many uses of ozone that are known to kill bacteria, eliminate smoke and react with alcohols, esters, saturated organics, acyclics, aromatic, heterocyclics and more to purify the air for healthier human consumption are used in certain methods according to this invention not to purify the air for human breathing, e.g., for a hunter normally in a very clean outdoor environment, but to react with odors emitted by humans so that these volatiles are not detected by an animal, e.g., a deer. Since ozone has a half-life of 20 minutes or more, airborne unreacted ozone still continues to clean bacteria, odors or clothing. In addition, any gear that has odor emanating from the gear is also cleaned. Without being bound by any theory, it is believed that in one aspect, ozone in the air kills bacteria in certain body areas, including, but not limited to, in the underarm and groin areas that is responsible for producing many of the odor-causing volatiles emitted by humans; and in another aspect, any volatile odors that are produced and emitted directly by humans via the skin are oxidized by the ozone into compounds that are much less volatile and therefore far less detectable to animals, e.g., deer. In another aspect, it is believed that any volatile odors that are produced and emitted directly by humans via the feet and escape through the shoe or socks are oxidized by the ozone into compounds that are much less volatile and therefore far less detectable to deer. In yet another aspect, it is believed that the more powerful (but much shorter life-time) hydroxyl and/or hydroperoxide radical oxidants that are produced by ozone reacting with ultraviolet rays of the sun and/or the UV lamp of an ozone generator and/or moisture in the air contribute to odor elimination.
In yet another aspect, it is believed that any pheromone or combinations of pheromones (which contain a wide variety of alcohol, ester, and saturated organic functionality) that are produced and emitted by humans at levels far too small to be detectable by humans but not by animals, e.g., deer, are oxidized by the ozone into compounds that are much less volatile and therefore far less detectable to animals, e.g., deer. In yet another aspect, it is believed that odorants in breath such as aldehydes, alcohols and acids are oxidized by the ozone into compounds that are much less volatile and therefore far less detectable to animals, e.g., deer. In yet another aspect, it is believed that it is possible that oxidized volatiles, even if they are still somewhat volatile and detected by animals, e.g., deer, are changed enough in composition that the animals, e.g., deer, no longer detects the oxidized volatiles as human.
In yet another aspect, it is believed that it is possible that higher levels of ozone in the environment around animals, e.g., deer, overpowers any human volatile such that the animals, e.g., deer, perceive the higher concentration of ozone as the result of commonly-occurring and natural lightning that may be miles away from the animals, e.g., deer.
Prior to descenting of clothes, use of special soaps, shampoos and carbon and/or metal containing clothing, or combinations of these is optional, but not necessary, when using ozone for animal encounters, e.g., hunting. There is no limitation to the number of ozone generators used except for taking the precaution of not allowing a person to come into contact with an unsafe amount of ozone that affects human health. For cost and convenience, one ozone generator located on or near a person is sufficient. Multiple generators located on a person, near a person as the person is walking, inside a blind, outside of a blind, and combinations thereof, may result in an especially enjoyable activity, e.g., a hunt.
The ozone generator or generators are, in one aspect, located approximately 1-2 feet above a person's head. It is within the scope of the present invention to locate an ozone generator at a person's feet or near any part of a person's body. Heights greater than about five feet above the head may be used, but it is possible that too much dispersion of the ozone results in less ozone contacting and then eliminating odors emanating from a person to effectively prevent an animal from detecting a human or to attract an animal. In certain aspects, an ozone generator is placed in a position that is substantially upwind of a person, e.g., a hunter, and slightly elevated above the person's head such that the ozone effectively contacts and then reduces or eliminates odors emanating from the person.
Referring now to FIG. 1, in one embodiment 10 of systems and methods according to the present invention an ozone generator G is located on a person P in a blind B, e.g., a hunter, especially when the person is walking to an activity site, e.g., a hunt site or engaged in an activity, e.g., hunting. The person P is wearing clothes C which may be any typical clothing or which may be any clothing disclosed herein according to the present invention.
Optionally the blind B has an interior ozone generator N and/or an exterior ozone generator R. Optionally an ozone generator T is placed outside the blind B. The person P may be outside the blind B. The blind may be a fabricated structure or a home-made blind on the ground or in a tree, e.g., made of conveniently located brush and foliage. The blind may be a unit such as an enclosure, hut, or a tent that is brought to the site or permanently located at the site.
According to certain aspects of the present invention, there is provided a method for the de-scenting of clothing used by sportsmen by the use of an oxidizing gas, namely, ozone or by ionization with UV light to produce hydroxyl and hydroperoxide ions. More particularly, clothing is treated with ozone or the hydroxyl and hydroperoxide ions either at home or in the field by the application of a small amount of ozone or the hydroxyl and hydroperoxide ions in order to remove the human scent or any other foreign scent. Also, the clothing of fishermen can be treated with the oxidizing gas while in the field to remove the odor of fish.
According to one embodiment of the invention, the human scent can be eliminated from clothing by applying a low volume stream of an oxidizing gas comprising ozone or hydroxyl and hydroperoxide ions directly on the hunter while he is wearing a hunting outfit. The gaseous stream is applied by an ozone generator which is hand held or a catalytic ionizer containing UV light and easily transported by the hunter. The gaseous stream can be applied directly to the clothing being worn by the hunter in an open atmosphere so as to be quickly diluted after it is passed over the clothing. Moreover, the gun or rifle or any other equipment, i.e. ammunition, arrows, scope, finders etc., of the hunter or sportsmen can be similarly treated to remove the gun or rifle or equipment odor.
In accordance with another embodiment of the invention, the human scent of a military person desiring to escape detection by other humans or scent animals (e.g., dogs) is reduced or eliminated enough to avoid detection. More particularly, there is provided a method for reducing or eliminating human or any other foreign scent from clothing, e.g., clothing and equipment used by military persons desiring to evade capture—through the use of ozone or hydroxyl and hydroperoxide ions produced by ionization in a manner that would not cause irritation or injury to the user or equipment.
In accordance with another embodiment of the invention, the clothing of the hunter can be treated before or after the hunt by placing the clothing in a container i.e. a sack, bag or box while passing the oxidizing gas into the container in order to remove any human or other scent foreign to that environment.
Another embodiment of the invention is that the generator is carried with a hunter or hung upwind of the body so it descents the human scent traveling downwind. In another embodiment of the invention, the generator is carried or placed with or near a hunter with little or no regard to wind direction, allowing for a full 360 degree hunt.
Also, some certain clothing is not cleaned after every use by the hunter or sportsmen such as gloves, hats, jackets, boots, and need to be deodorized and decontaminated before next use.
According to a further embodiment of the invention, the odor of fish can be eliminated from a fisherman's clothing, body or equipment by the direct application of a stream of ozone gas or hydroxyl and hydroperoxide ions to the site of the fish odor. Additionally, a fisherman's hands can be deodorized with ozone so as to remove the fish odor without causing irritation.
Each of the methods can be practiced in the open in the field of sports activity utilizing a low volume gas generator. The clothing is not decolorized as in applications involved in high volumes of ozone as found in the garment industry where ozone is used to both de-size and/or decolorize denim garments. The oxidizing gas may be used alone or diluted with air as when packaged in a compressed gas form. Ozone which is produced by generators in amounts up to 8000 mg/hr or more can be compressed or diluted with an inert gas and compressed into small containers.
It is understood that the term “sportsmen” is meant to include those individuals who may hunt with a camera or who merely enter an environment to observe animals in their habitat.
Additionally, the term “fishermen” includes those individuals who handle the fish caught by others.
Hydroxyl and hydroperoxides are produced in a process known as “Radiant Catalytic Ionization” which utilizes ultra violet light which activates a photocatalytic target.
Small ozone generators such as those producing 1 to 25 lbs. of ozone per day can be utilized. Also the ozone can be applied from compressed ozone-filled containers similar to compressed air.
Low volume ozone generators which generate up to 65 mg/hr of ozone and are portable as well as high volume ozone generators are currently sold by EcoQuest International of Greeneville, Tenn. which also sells the generators of hydroxyl and hydroperoxide ions.
It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention without departing from the spirit or scope of the invention as broadly claimed.
The present invention discloses methods of reducing or of eliminating any scent that is foreign to the environment from the clothing, equipment and body of sportsmen, by generating a volume of ozone gas or a gaseous stream of hydroxyl and hydroperoxide ions produced by catalytic ionization and passing the gas over the clothing, body, or equipment. Such a method may include any of the following: wherein said scent is human scent or any other scent that is not natural to the environment; passing said gas over a gun or rifle of said sportsman; wherein said sportsman is a hunter; wherein said scent is fish odor; wherein said gas is generated by a hunter at the field of the hunt; wherein the clothing is treated with said gas while being worn by the sportsmen; wherein said clothing and equipment is treated with said gas when in a container; wherein said gas is ozone; wherein said gaseous stream is produced by catalytic ionization; and/or wherein said gas is compressed and delivered from a container. The present invention discloses a method for removing the human scent and any other scent that is not advantageous to the environment you are in from clothing and equipment used by sportsmen by the use of gaseous ozone or hydroxyl and hydroperoxide ions. The gas is applied directly or indirectly to the clothing, equipment and body while the hunter is in the field and/or prior to or after the hunt. The method can also be used by fishermen to eliminate fish odor. The method can include delivering a gas in compressed/generated form from a generator that is a container.
The following Examples further illustrate the invention, but are not intended to be limiting thereof. In these examples ozone concentration monitoring was done with an OS-4HIGH RANGE™ ozone sensor from Eco Sensors, Inc. of Santa Fe, N. Mex.

After 30 minutes both tents had 10 odor (on the POS scale). Then the ozonator with the plug-ins at a control setting of MAX ODOR, was turned on and ozone levels in the tent with the ozonator rose as follows (with odor levels in both tents, on POS scale, as indicated):


0 minutes = 0.00 ppm
1 minute = 0.26 ppm
2 minutes = 0.50 ppm
3 minutes = 0.71 ppm
4 minutes = 0.87 ppm
5 minutes = 1.02 ppm	(odor in ozonated tent, 4; in control tent, 10)
15 minutes = 2.43 ppm	(odor in ozonated tent, 3; in control tent, 10)
21 minutes = 2.35 ppm	(odor in ozonated tent, 3-4; in control tent, 10)

At 21 minutes, turned output of both plug-ins to a 0.5 central control setting.


31 minutes = 2.42 ppm
36 minutes = 2.34 ppm	(odor in ozonated tent, 4; in control tent, 10)
41 minutes	(unplugged both plug-ins and removed from
	tents)
56 minutes = 2.97 ppm	(odor in ozonated tent, 1; control tent, 10)
71 minutes	(set both plug-ins on a “low” control setting in
	each tent)
81 minutes = 2.81 ppm	(odor in ozonated tent, 1; control tent, 10)

Example XXIV

The OBSESSION™ fragrance was sprayed (2 sprays) each onto one sweat shirt, one camouflage t-shirt (short sleeved), one camouflaged long-sleeved t-shirt, one pair of denim jeans, one cotton short pants and one cotton t-shirt. All the clothes were placed in a bag as in Example XIII in no order along with a PRO 3400™ ozone generator. The smell at time=0 in the bag was a 10 on the POS scale. After 95 minutes treatment with ozone in the bag, each garment had a less than 1 smell on the POS scale. Ten hours later, all the clothes placed in the bag still had ozone odor on them. At this time all the clothes were placed in an unsealed plastic bag and another 14.5 hours later the clothes still had ozone odor on them.

Example XXV

One spray of COON URINE™ Hunter's Masking Scent was sprayed onto a t-shirt. The t-shirt was placed into a bag as in Example XIII along with a BORA IV LIVING AIR™ ozonator (fan on max). The results are shown below for the indicated number of minutes of treatment with ozone in the bag:
0 minutes=10 odor (odor of shirt on POS scale)
5 minutes=6 odor
10 minutes=2 odor
15 minutes=1 odor

Example XXVI

One spray of the OBSESSION™ cologne was sprayed onto a POLAR TEC™ fleece jacket and placed into a 150 quart cooler fitted with a clothes rod and hanger. The fleece jacket was placed on the hanger and a PRO 3400™ ozone generator was placed into the cooler. The smell at time=0 in the cooler was a 10 on the POS scale. After 15 minutes treatment with ozone, the garment had about a 1 smell on the POS scale.

Example XXVII

One spray of the OBSESSION™ cologne was sprayed on a green long-sleeved shirt (100% cotton knit) and placed in the cooler as described in Example XXVI along with a PRO 3400™ generator. A small fan was placed in the bottom of the cooler and turned on max with the fan facing up. The smell at time=0 in the cooler was a 10 on the POS scale. After 15 minutes of treatment with ozone in the cooler, the shirt had about a 1 smell on the POS scale. Then the shirt was re-placed in the cooler and treated with ozone for an additional 30 minutes. This resulted in several red streaks on the shirt due to the ozone contacting and remaining on the shirt. The shirt was then removed from the cooler and placed on a table open to the ambient air. About eleven hours later, the shirt still had an ozone smell and almost all the red streaking had disappeared. Another 12 hours later minimal ozone smell was noticeable and all red streaking had disappeared.

Example XXVIII

A sweaty t-shirt that a human jogged in for 3.5 miles over 35 minutes was placed on a hanger in the cooler of Example XXVI along with a PRO 3400 (Trademark) ozone generator and a small fan in the cooler was turned on high. The smell at time=0 in the cooler was a 10 on the POS scale. After 20 minutes treatment with ozone in the cooler, the garment had about a 2 smell on the POS scale.

Example XXIX

A hunter placed himself in a cedar bush located in the Fort Peck Wilderness Area in Montana. A Biozone 50™ battery-operated ozonator was placed on a backpack located between the hunter's legs and turned on. An elk was observed approaching within 8 yards of the hunter about 45 minutes after the ozonator was turned. The elk passed downwind and through the hunter's scent line without detecting the hunter.

Example XXX

A hunter placed himself in a home-made blind of native brush in South Texas along with an OMZ-200™ battery operated ozonator hung from the blind and located about 10 inches behind and above his head. The hunter did not use any SCENT-LOK™ clothing, masks or scents prior to or during the hunt, but was camouflaged using Cabela's lightweight ghillie pants, jacket and facemask. Deer corn was placed at the perimeter of the blind going out to about 30 feet from the blind. Within 10 minutes of turning on the ozonator to Max Setting, up to 6 white tail deer at a time and several birds (cardinals and finch) were observed feeding within 10 yards downwind of the hunter in a 3 hour time span. One young buck was observed within 5 feet downwind of the blind where the hunter was laying. None of the deer, cardinals or finch appeared to have scented the hunter.
Optionally, a feeder FR is provided to attract an animal (e.g., but not limited to, a grain feeder for attracting a deer or a bird feeder for attracting a bird). Any known feeder may be used, including but not limited to, an automatic powered timed feeder.
