Definitions

  • the present invention relates to an article for delivery of a fragrance.
  • the article comprises a plurality of carrier materials including a first carrier material comprising at least one first fragrance and a second carrier comprising at least one second fragrance.
  • the article is adapted for providing selective interconnectivity of the first carrier material and the second carrier material, by e.g. by manual set up of the customer, such that the at least one first and the at least one second fragrance are simultaneously released.
  • the present invention further provides the use of the article for delivery of a fragrance as air freshener or in an air freshener for home, toilet, cellar, wardrobes, dish wash, suitcase, handbags, automobile and mattress applications.
  • Various types of air fresheners have been made to dispense fragrances and scents to mask or neutralize unpleasant odours or to simply provide a pleasant scent in a volume of air.
  • Conventional liquid air fresheners generally comprise a reservoir containing a mixture which may be a true solution, a colloidal solution or a microemulsion of a perfume with a solvent into which dips a wick which is connected to an emanating surface. The perfume mixture travels up the wick to the emanating surface from which the perfume evaporates and freshens the surrounding atmosphere.
  • Perfumes used in those air fresheners are generally oils and are therefore generally insoluble in water in the absence of any other agents.
  • fragrances may be also dissolved in water, although it is often necessary to use a surfactant or other emulsifying agent to dissolve the fragrance in water.
  • the fragrance evaporates with the carrier, scenting the air.
  • Solid or gel form fragrances are more desirable for products such as air-freshener used in rooms and automobiles. Diluting the concentrated solid air freshener at the point of use or at an intermediate location to form a liquid reduces the cost and space required to transport and store the air freshener.
  • US 5,139,864 A discloses a multi-layer sequentially timed release polyfunctional volatilizable substance delivery article.
  • An outermost matrix layer initially evolves its contained volatilizable substance at a rate substantially greater than the rate at which its neighbouring matrix layer evolves its contained volatilizable substance until such point in time that sufficient volatilizable substance contained in the outermost matrix layer has been evolved into the environment surrounding said article, that a substantial portion of the surface of the neighbouring matrix layer is at least constructively exposed to the surrounding environment thereby permitting a substantial increase in the rate of emission of volatilizable substance from the neighbouring matrix layer.
  • US 5, 150,722 A discloses a multi-layer sustained release scent emitting article with a scent emitting exposure surface area comprising two barrier layers covering planar surfaces of a functional ingredient-containing material. An initial burst of a functional material over a relatively short period of time may be provided.
