Definitions

  • the present invention relates to methods and devices for emitting volatile compositions.
  • the invention relates to a method and devices for emitting two or more distinct volatile compositions.
  • the Whitby, et al. patent application discloses a method and device adapted to provide to a space, two or more fragrance compositions, at least one of which fragrance compositions is provided periodically.
  • the method and device may provide a continuous supply of a first fragrance composition and a periodic supply of a second fragrance composition.
  • the fragrance composition(s) may be vaporized by heating and may include deodorant and/or insecticidal compounds.
  • the fragrance compositions are preferably chosen such that the two fragrance compositions contrast with one another or have different notes.
  • the fragrance composition is generally pulsed from a device which includes a heater.
  • the periodic supply of heat to release the fragrance composition is controlled by providing the device, and particularly the heater, with a controller.
  • the controller is in the form of an electronic circuit.
  • the controller is arranged such that the heater runs for a short period of time, preferably from 15 seconds to 15 minutes with “appropriate intervals of time there between”.
  • the Whitby, et al. patent application appears to be directed primarily to maintaining or sustaining the olfactory impact of the fragrance composition being emitted continuously, rather than to providing to the user noticeable changes in fragrances.
  • the Whitby, et al. patent application mentions periodic supply of two or more fragrances, there is no specific teaching of emission patterns or programs dictating the supply of the different fragrances relative to each other so that the users actually experience distinct fragrances rather than one fragrance which is a blend of the two compositions.
  • the present invention relates to methods and devices for emitting volatile compositions.
  • the invention relates to a method and devices for emitting two or more fragrance compositions.
  • the method it may be desirable for those who either experience the emission of the fragrance composition(s), or who are in the presence of the device(s) emitting fragrance composition(s), to experience and/or perceive a pleasant scent all of the time. In other cases, this may not be all of the time, but all of the time that such persons wish to perceive a fragrance.
  • the method in which the method is used to emit two or more fragrance compositions, it may be desirable to maximize the perceptibility of each of two or more separate and distinct fragrance compositions. Thus, the method can do more than merely prevent habituation to a given fragrance composition.
  • the volatile compositions are alternately emitted during discrete emission periods that are greater than 15 minutes and less than or equal to 24 hours.
  • the device can automatically switch to alternate the volatile composition being emitted.
  • the device may emit volatile compositions for periods less than or equal to 15 minutes; or it may emit volatile compositions for periods greater than 24 hours (e.g., 48 hours). Numerous other embodiments are possible.
  • the method can utilize one or more devices.
  • a single device that is a dual scented “plug-in” that switches back and forth between two (or more) scents.
  • This embodiment of the device has a housing, and the housing is supported on an electrical outlet by a plug at least indirectly joined to the housing.
  • the device contains a first volatile composition and a second volatile composition.
  • the first volatile composition is emitted in an alternating period relative to said second volatile composition.
  • the method described herein can be carried out by two or more dispensing devices.
  • Such dispensing devices comprise any type of dispensing device, including, but not limited to aerosol sprayers.
  • FIG. 1 is a diagram that shows one non-limiting embodiment of an emission program for emitting two volatile compositions.
  • FIG. 2 is a diagram that shows one non-limiting embodiment of an emission program for emitting three (or more) volatile compositions.
  • FIG. 3 is a diagram that shows one non-limiting embodiment of an emission program for emitting two (or more) volatile compositions where there is a gap between the emissions of the volatile compositions.
  • FIG. 4 is a diagram that shows one non-limiting embodiment of an emission program for emitting two (or more) volatile compositions where there is an overlap of the emissions of the volatile compositions.
  • FIG. 5 is a diagram that shows one non-limiting embodiment of an emission program for emitting three (or more) volatile compositions where there is an overlap of the emissions of one volatile composition with the emission of two other volatile compositions.

  • the present invention relates to methods and devices for emitting volatile compositions.
  • the invention relates to methods and devices for emitting two or more volatile compositions.
  • the methods for emitting volatile compositions can comprise a variety of different embodiments.
  • the two or more volatile compositions can be fragrance compositions, compositions that function as insecticides, air fresheners, deodorants, aromacology, aromatherapy, insecticides, or any other material that acts to condition, modify, or otherwise charge the atmosphere or to modify the environment.
  • the two or more volatile materials emitted in a given embodiment of the method can be the same type of material (e.g., two or more fragrance compositions), or they can be different types of materials (e.g., fragrance compositions and air fresheners).
  • Deodorants, or malodor control compositions may comprise a material selected from the group consisting of: odor neutralizing materials, odor blocking materials, odor masking materials, and combinations thereof.
  • the methods can emit the volatile compositions in a sequence in which the emission of the different volatile compositions automatically alternates between the different volatile compositions.
  • the volatile compositions can be emitted in any suitable sequence.
  • the sequence of emission of the volatile compositions can be in a pattern, or it can be random.
  • the term “pattern”, as used herein, refers to repeating sequences. In embodiments where the sequence of emission of the different volatile compositions is repeatable, the pattern can be repeated once, or any number of times after the initial sequence.
  • the term “random”, as used herein, refers to sequences in which the sequence of emission of the volatile compositions does not repeat in a regular fashion. It is also possible for an emission sequence to comprise a portion of time where the sequence is in a pattern, and a portion of time in which the sequence is random.
  • two or more volatile compositions are emitted in an alternating sequence.
  • there can be a first volatile composition and a second volatile composition and the first volatile composition is emitted in an alternating period relative to said second volatile composition.
  • the volatile compositions can be emitted in an alternating pattern as follows: 1, 2, 1, 2, . . . , etc.
  • FIG. 1 shows such an emission program schematically.
  • the diagram represents the periods during which that the volatile compositions are being subjected to a source of energy (or “activated”) (for example, if they are in a device which has a heater that heats the compositions, the diagram can designate the periods of time that during which the heaters are on and off). If there are three volatile compositions, they can be emitted in an alternating pattern as follows: 1, 2, 3, 1, 2, 3, . . . , etc. as shown in FIG. 2.
  • volatilization source such as a heater
  • volatilization sources for the volatile compositions.
  • a single volatilization source can be used to volatilize more than one volatile composition.
  • Such a volatilization source could, for example, be capable of moving to volatilize the different volatile compositions, or it can be capable of selectively directing energy (e.g., heat) to the different volatile compositions (such as by opening and closing a door or gate between the volatilization source and a given volatile composition).
  • containers can be movable relative to the volatilization source (so that the containers can be selectively moved over a heater, for example).
  • the term “interval”, as used herein, refer to the shortest period of time in the emission sequence.
  • the discreet emission periods can also be referred to herein as a first time period, a second time period, etc. (each of which has a beginning and end). It should be understood that it is not necessary that the different volatile compositions be emitted for equal time periods.
