Definitions

  • This invention relates generally to dispensers for use with air-treating formulations, preferably air freshening formulations. More particularly, this invention relates to a novel air treatment formulation and a method and apparatus for dispensing the same.
  • odors tend to gather in areas such as those existing in homes, offices and the like. As is also well known, on occasion these odors can be unpleasant, and the unpleasant odors can gather in an area in these structures. This tendency of malodors to gather is exacerbated in homes and other buildings that are constructed in an energy-efficient manner. Typically, homes and other buildings are constructed in a manner that essentially prevents air circulation between the inside and outside of the building. In these buildings malodors can accumulate to offensive levels.
  • the present invention relates generally to the treatment of air for a wide variety of purposes, including removing malodors, removing or killing germs and the like
  • this invention and the problems it addresses will be described primarily with reference to air treatment in the form of air freshening, namely the adding of fragrances to the air such that the odors which tend to accumulate in such buildings and/or homes can be effectively treated.
  • air treatment in the form of air freshening, namely the adding of fragrances to the air such that the odors which tend to accumulate in such buildings and/or homes can be effectively treated.
  • a wide variety of devices and methods are known for the dispensing of fragrances to the air.
  • known devices can be characterized as being configured for instant treatment of the air, continuous treatment of the air, or a combination of both.
  • Exemplary of instant treatment devices are the well- known aerosol spray cans which contain aerosols comprising a fragrance, which aerosols can be sprayed throughout a particular room or building.
  • Exemplary of continuous air- treating devices are those devices which generally comprise a fragrance impregnated and/or releasing element which is suitably placed in an area were freshening is desired.
  • the present invention has particular usefulness in connection with instant treatment type devices.
  • these types of devices for dispensing fluid from aerosol containers generally include a spray stem or spray head which, when actuated, disperses fluid from the container.
  • the fluid preferably comprises a fragrance (e.g. perfume).
  • a widely-employed procedure for packaging such fluids e.g.
  • fragrance-containing fluids and facilitating their dispersion into the air is through the use of aerosol products (e.g. hydrocarbon products).
  • aerosol products e.g. hydrocarbon products.
  • the fragrance (perfume) is dissolved or dispersed in a fluid composition, normally an aqueous solution, and carried by a propellant, such as a hydrocarbon, in a container having a valved spray nozzle.

  • the fragrance intensity values for these compositions were therefore evaluated not only after initial dispensation, but also at 2 hour intervals for three intervals, i.e., at 2 hours, at 4 hours and at 6 hours.
  • the results are set forth in Table 3. TABLE 3
  • a preferable composition useful in the context of the present invention possesses a fragrance intensity after initial dispensing in die range of about 2.0 to 6.0, preferably about 4.0 to about 6.0. As shown, these formulations are preferably capable of maintaining a fragrance intensity of 3.0 to 4.5 after 2 hours, and a fragrance intensity of about 2.2 to about 4J after 6 hours.
  • preferred fragrance compositions have, with continued reference to Table 3, initial fragrance intensities preferably in the range of or greater than about 2.6, more preferably in the range of or greater than about 4.2, and optimally in the range of or greater than about 4.4.
  • These fragrance compositions suitably have desirable longevity characteristics such that the fragrance intensity of a preferred fragrance composition remains in the range of or greater than about 2.2, more preferably in the range of or greater than about 2.8 and optimally in the range of or greater than about 3.0 for at least 2 hours after initial dispensing.
  • fragrances other materials are or may be useful in connection with the present invention.
  • materials include but are not limited to deodorizers, biologically active disinfectants, bactericides, insecticides and insect repellents, insect pheromones, plant nutrient regulators and die like.
  • compositions in accordance wim the present invention have desirable fragrance intensities. While the mechanism underlying these results is not completely understood, it is possible that these enhanced fragrance intensity readings result from the improved dispersion of the perfume as enabled by the alcohol, solvent or solvent/co-solvent mixture carrier.
  • the alcohol, solvent or solvent/co-solvent mixture may cause the perfume to be dispersed in very fine particles in a rapid fashion such that the fragrance is readily dissipated into the air. Given the high quantity of perfume contained within the compositions and die fine dispersion of those compositions in the air surrounding apparatus 10, long-lasting fragrances are obtainable.
  • Container 20 preferably is provided widi a fragrance formulation having one of die foregoing compositions. Once so provided, container 20 is "loaded” into apparatus 10. In particular, and with reference to Figures 4 and 6, e loading of apparatus 10 and use of the loaded apparatus 10 will now be described.
  • tabs 46 and 48 are preferably provided widi sloping leading edges 96 and 98 which facilitate ease of insertion of container 20 into retainer 30.
  • Apparatus 10 is now ready for dispensing of die formulation contained within container 20.
  • actuating stem 24 is depressed, diereby causing release of the fragrance formulation dirough delivery aperture 26 to dispensing aperture 16 of upper portion 12.
  • a misting spray S is produced.
  • a metered amount of the fragrance composition is released through valve 22, thus ensuring that the air treating formulation is not wasted and me fragrance is optimally dispersed.
  • any residue which is collected from spray S or which remains from spray S can be collected in collection reservoir 18, dius preventing any residue from running down d e side of apparatus 10.
  • the perfume contained within the formulation is readily and widely dispersed in die air surrounding apparatus 10. This efficient dispersion tends to enhance longevity of the fragrance as well as intensity of the fragrance, as compared to results from other air freshener devices.
  • the useful life of container 20, and tiius apparatus 10 widi which it is used, is enhanced. Once die metered dose is released from valve 22, valve stem 24, and tiius upper portion 12, are returned to their normal closed positions. If desired (although generally not necessary), additional doses can be immediately obtained by again depressing upper portion 12 wid respect to lower portion 14.
  • container 20 can be directly removed from apparatus 10 in a fashion tiiat reverses the loading process described hereinabove.
  • tabs 46 and 48 can be manually separated and container 20 removed from housing 30 of apparatus 10.
