Definitions

  • Dispenser for dispensing an active ingredient
  • the present invention relates to a dispenser for dispensing an active ingredient, in particular a fragrance.
  • the present invention relates to a method for producing the dispenser for dispensing an active ingredient and the use of the dispenser for scenting rooms, dishwashers, refrigerators, for masking or neutralizing an unpleasant smell, for textile care, in particular for scenting and / or conditioning textiles , in particular when washing, drying or chemical cleaning of textiles, for the delivery of insect repellents, for the release of biocides, as toilet scent washers, or for the release of aroma substances.
  • fragrances and fragrances have molecular weights of up to about 200 daltons. Due to the different volatility of fragrances, the smell of a perfume composed of several fragrances or fragrances changes during evaporation, whereby the odor impressions in "top note"("topnote”),”heart or middle note”("middlenote.” ”Or“ body ”) and“ base note ”(“ end note ”or“ dry out ”). Since the smell is largely based on the intensity of the smell, the top note of a perfume is naturally by volatile compounds determined, while the base note consists largely of less volatile fragrances.
  • a basic method for the targeted release of fragrances or fragrances, e.g. from detergents, is their direct addition to the application formulation.
  • the disadvantage of this process is the immediate release of the fragrance or fragrance from the formulation, which greatly reduces the shelf life of such formulations. Due to their slight volatility, when using conventional detergents or cleaning agents, only a small proportion of the fragrance used remains on the treated object after use, in particular after washing, which only leads to a short-term fragrance effect.
  • fragrances in the form of fragrance particles are either used as an integral part of a detergent or cleaning agent, or dosed into the washing drum directly at the start of a washing cycle in a separate form, for example in the form of a fragrance concentrate or as fragrance beads.
  • a fragrance concentrate or as fragrance beads By changing the wash liquor several times during a wash cycle, the majority of the dosed fragrance particles are dissolved or rinsed out with the wash liquor before the last rinse cycle, which means that the laundry cannot be adequately scented.
  • Textile treatment composition described on the basis of a sublimable carrier.
  • the active ingredients of the compression-molded textile treatment composition are melt-worked into a sublimable carrier, for example a sublimable hydrocarbon or a sublimable polar compound. Incorporation into a shaped body prevents excessively rapid volatilization and thus loss of the active ingredient contained. The effect of the active ingredient can thus be kept at a constant level for a long period of time.
  • devices based on membranes for delivering volatile substances such as fragrances or insect repellants to the immediate environment surrounding them include a liquid reservoir, a liquid volatile agent, an evaporation membrane and a peelable cover layer.
  • the active substance after activation, is evaporated to the surroundings by pulling off the covering layer through the evaporation membrane.
  • Dispensing systems of this type are mainly used for scenting rooms, as so-called “air fresheners”.
  • WO 2016/199081 A1 describes a membrane fragrance dispenser for room scenting, in which the cover film is not removed completely but rather in areas from the evaporation membrane and only part of the evaporation surface is activated.
  • the evaporation membrane is a microporous, vapor-permeable membrane that is formed from a polymer matrix.
  • WO 2017/131950 A1 discloses a dispenser system for dispensing liquid volatile substances such as insect repellants, fragrances or deodorants into the environment, the volatile active substances diffusing through a membrane.
  • the membrane is made of polyethylene.
  • DE 20 2007 003 050 U1 describes an active substance container for dispensing liquid and / or gel active substances into the environment by means of diffusion.
  • the membrane film used there is a composite polymer film, for example made of ethylene, ethylene vinyl acetate, ethyl acrylate or polyethylene.
  • Non-porous evaporative membranes are typically saturated by the liquid volatile substance prior to activation. Since non-porous membrane is driven by gradient concentration, if the volatile substance does not evaporate easily from the outside of the evaporation membrane, no further volatile liquid can be transported through the evaporation membrane. Furthermore is a membrane driven by gradient concentration depending on the size of the surface of the membrane that is in direct contact with the volatile substance. Therefore, when part of the volatile substance from the reservoir is used up, the maximum evaporation surface cannot be used. As the level of volatile substance decreases over time, the evaporation rate decreases proportionally. In addition, such non-porous membranes can be adversely affected by contact with many volatile substances. Such non-porous membranes therefore limit the manufacturer of such devices to a limited number of volatile substance formulations.
  • porous evaporative membranes can overcome some of the shortcomings observed with the use of membranes driven by gradient concentrations. Porous membranes are generally driven by capillary action. These porous membranes enable a wider range of volatile substance formulations. In addition, they allow all of the liquid volatile substance to be depleted from the outer surface of the porous membrane with a uniform release of vapor.
  • membranes known in the prior art for example non-porous polyethylene membranes
  • polar volatile substances which is a selection of active ingredients, for example fragrances, limited.
  • porous membranes in an evaporation dispenser leads to the accumulation of the liquid volatile active substances on the outer surface of the membrane, so that the membrane surface becomes wet and the active substances can drip onto the surrounding surfaces.
  • perfume oil ingredients these can deform or dissolve certain plastic materials. The result is the damage to the plastic membrane of the dispenser itself and the surrounding materials.
  • certain perfume oil ingredients can also dissolve colors.
  • the escaping liquid also makes it uncomfortable to use the fland, and contact with the active ingredient, which can possibly lead to skin irritation, cannot be ruled out.
  • a dispensing device which, in the case of objects to be treated, preferably textiles, on the one hand ensures an improved release of active substance, preferably an improved object scenting, and on the other hand prevents the accumulation of the volatile liquid active substances on the outer surface of the dispensing device , enables a more comfortable cultivation and avoids the dull contact during use.
  • the present invention is therefore directed to a dispenser for dispensing a volatile active substance, in particular a fragrance, comprising:
  • a container for receiving an active substance composition which has a cavity, at least one container opening and a container edge;
  • an active ingredient composition comprising or consisting of:
