Definitions
- the present invention relates to devices that dispense a volatile air treatment chemical by heating a substrate that is impregnated with, or coated with, the chemical. More particularly it relates to methods for constructing the substrate to create an array of pore size distribution therein, substrates produced thereby, and such substrates further formed with a rechargeable start-up projection.
- Substrates particularly porous substrates have previously been used as carriers for air treatment chemicals such as insect control agents (insecticides, insect repellents, insect growth regulators, attractants, synergists, etc.), fragrances and deodorizers. See e.g. U.S. patent 6,551,560.
- a volatile air treatment chemical is caused to be dispensed from the substrate.
- the heating source is typically an electrical heater, but may instead be a flame in some cases.
- a porous substrate impregnated with volatile insecticide can be used to inhibit mosquito biting in a confined bedroom.
- a deodorizing or other odor control material can be dispensed to overcome malodors, or to simply provide a desired fragrance.
- the substrate usually rests against or near a heater.
- the heater heats the substrate, causing the volatized air treatment chemical to be driven off the substrate in a direction away from (essentially perpendicular to) a heater surface.
- This can create some inefficiencies.
- the portion of the substrate adjacent the heater can act as an insulator for the portion of the substrate which is releasing the active, making control of the dispensing more difficult.
- Another problem with such devices is that it may take a while after usage begins to adequately treat the air in a defined environment adjacent the device. For example, when someone is about to go to bed they may activate the device in a bedroom. It is undesirable for them to have to wait a long period before feeling secure about insect protection in the room.
- U.S. patent 5,948,425 disclosed in an enlarged outer end of the coil that would initially burn to create a burst of insecticide, before the rate of burning slowed down to a steady state.
- U.S. patent 6,551,560 disclosed that a central region could be provided having the ability to provide a quick burst of active, followed by the surrounding area releasing active at a slower constant rate. While these patents therefore addressed the need for quickly treating a room at the beginning of operation, they did not address a way to have the same device provide such a burst on multiple days.
- wicks could be formed from sand (and certain other particulate material) mixed with a binder.
- the wicks could draw active from a reservoir to an upper portion of the wick, and the upper portion of the wick could be positioned adjacent to (usually through) a heater unit to volatize the active.
- U.S. patent application publication 2004/0151747 there is a discussion of forming the wick of silica sand particles bound with a novolac resin.
- the volatile material was described as optionally being an insecticide dissolved in a hydrocarbon solvent and/or a fragrance.
- the invention provides a substrate that can actively dispense a volatile air treatment chemical upon being heated.
- the substrate is preferably a porous substrate having granular particles adhered together to form a body having a network of pores.
- Volatile air treatment chemical is disposed in the pores (e.g. by dosing the substrate with neat air treatment chemical or by leaving the substrate in a well filled with the active and allowing the active to seep into the substrate).
- other conventional means for impregnating the substrate can be used.
- the substrate has a first end and a second opposed end, and the average size of the granular particles adjacent the first end is less than the average size of the granular particles adjacent the second end.
- the substrate is configured such that the first end tends to wick air treatment chemical towards itself as air treatment chemical is dispensed from the first end.
- the granular particles comprise sand bound to a phenolic resin.
- a projection e.g. an axially projecting nose extending from a frustum shaped base
- a projection is formed adjacent the first end to provide a first burst of volatile air treatment chemical when the substrate is first heated adjacent the projection.
- the invention provides a method for forming a substrate that can actively dispense a volatile air treatment chemical upon being heated.
- the average particle size of the substrate at the bottom of the substrate in the mold will be less than the average particle size of the substrate at the top of the substrate in the mold.
- the sand can be impregnated after the shaking step and before the forming step. Alternatively, it can be impregnated by exposing the already-formed substrate to the impregnation fluid.
- the substrates of the present invention are inexpensive to produce, use heat extremely efficiently, and are capable of multiple initiation bursts.
- FIG. 2
- FIG. 5 is a view similar to FIG. 4. but with the mold shown partially filled;
- a removable indicator unit 26 allows the indicator unit 26 and/or the substrate 22 to be separately replaced.
- the indicator chemical may be directly housed in a well of the cartridge unit 18.
- the device 10 is most preferably plugged into an electric socket on a vertical wall.
- appropriate electric sockets on horizontal or other surfaces may also be used to provide power.
- the terms such as “front”, “rear”, “upper”, “lower”, and “side” should be interpreted in an analogous manner when the devices are used for that type of installation.
- the housing 12 has a series of elongated vents 30 on the upper and lower sides of the housing 12.
- the vents 30 allow in air from the environment and permit it to pass along with the air treatment chemical dispensed from the substrate 22 through the vents 30 on the upward side of the housing 12. Nose 25 of the substrate
- the heating element 22 is preferably positioned closely adjacent the heating element 56 with room around the nose 25 for air to pass completely around its periphery.
- the preferred cartridge unit 18 has a substrate 22 having a forward frustum shaped section 23 and a rearward projecting nose 25.
- the particular shape of the substrate 22 is not critical insofar as the broadest aspects of the invention are concerned.
- the projecting nose 25 has certain advantages for quick start-up in some preferred embodiments.
- the substrate 22 is preferably impregnated with a volatile air treatment chemical capable of being dispensed from the substrate 22 when the substrate 22 is heated.
- the substrate 22 may instead be only partially impregnated.
- the extent of dispensing of the air treatment chemical can be indicated by a visible cue whose appearance results from the dispensing of an indicator chemical 28 associated with the indicator unit 26.
- the substrate 22 has a first end 60 and a second end 62 opposed to the first end, and the average size of the granular particles adjacent the first end 60 is less than the average size of the granular particles adjacent the second end 62.
- the substrate 22 is preferably positioned in front of the heating element 56 with the nose 25 of the substrate 22 (containing the highest density and smallest pore size) closest to the heating element 56.
- heat is applied to at least an end and side walls of the nose of the substrate. This causes a first burst of the volatile air treatment chemical to be dispensed from the substrate.
- the nose of the substrate is preferably allowed to cool, thus permitting additional volatile air treatment chemical to be drawn from the substrate to the nose 25. Then, the substrate is re-heated such that heat is applied to at least a rearward end and side walls of the nose, causing a second burst of volatile air treatment chemical to be dispensed from the substrate.
- a method for forming the substrate 22 of the present invention is schematically depicted.
- a mold 64 of the substrate 22, having a projecting nose 70 is filled with the substrate material, preferably a sand/resin mix.
- the mold 64 is then covered with a lid 66 and shaken. By shaking the mold 64, the sand particles 68 having a smaller size are shifted downward, towards the nose 70 of the mold 64. In this manner, a substrate 22 having smaller particle size at the bottom end and larger particle size at the top end of the substrate 22 is formed.
- Examples of a suitable substrate 22 include but are not limited to porous sand with a binder such as novolac resin, urethane resins or highly cross linked thermoplastics such as cross linked polyethylene.
- sand substrates can be made in a fashion analogous to the sand wicks described in U.S. patent application publication 2005/0284952.
- Alternative substrates include other particulates such as metal, cellulose and ceramic particulates.
- the air treatment chemical is preferably an insecticide, fragrance and/or disinfectant. In some cases more than one air treatment chemical may be used alone or in combination in the substrate 22.
- the air treatment chemical is an insecticide and/or insect repellent, organic phosphorous insecticides, lipidamide insecticides, natural repellents as citronella oil, natural pyrethrins and pyrethrum extract, and synthetic pyrethroids are preferred.
- Suitable synthetic pyrethroids are acrinathrin, allethrin as D-allethrin, PynaminRTM, benfluthrin, bifenthrin, bioallethrin as Pynamin ForteRTM, S- bioallethrin, esbiothrin, esbiol, bisoresmethrin, cycloprothrin, cyfiuthrin, beta- cyfluthrin, cyhalothrin, lambda-cyhalothrin, cypermethrin, alpha-cypermethrin, beta- cyperrnethrin, cyphenothrin, deltamethrin, empenthrin, esfenvalerate, fenpropathrin, fenvalerate, flucythrinate, taufluvalinate, kadethrin, permethrin, phenothrin, pralle
- the volatile insecticide is selected from the group consisting of transfluthrin, metofluthrin, vapothrin, permethrin, prallethrin, tefluthrin and esbiothrin.
- Transfluthrin is the most preferred insecticide.
- Possible solvents for carrying these air treatment chemicals include, but are not limited to, ISOPARTMC, ISOPARTME, ISOPARTML, heptane, methanol, acetone, ethanol, isopropyl alcohol, dodecene and tetraydrofuran.
- ISOP ARTMC, ISOP ARTME and ISOP ARTML are hydrocarbon solvents of varying chain length and are available from Exxon Chemical Company.
- Non-limiting examples of these perfumes include animal-based and plant-based natural perfumes, and artificial perfumes such as alcohols, phenols, aldehydes, ketones, terpenes, and esters
- preferred disinfectants include, but are not limited to, glycols, trimethylene and dipropylene.
- Organic acids compatible with the use of the substrate 22 and environment may also be used.
- the mold 64 should be filled to capacity, thereby creating a substrate 22. The sand or other particulate should be shaken thoroughly in the mold (e.g.
- the lid 66 can be present during the shaking. However, it is preferred that it be removed with the top of the sand smoothed, by dragging a blade across it, prior to starting the heating.
- the front wall had a diameter of 1.6 cm and the rear nose had a rear view maximum diameter of 0.5 cm.
- the mold 64 used to form the substrate 22 of the present invention may be made from any suitable material, including but not limited to plastic, metal or wood molds. Hence, the mold itself is not critical.
