Description

 Fan wheel and air freshener for continuous and, if necessary, increased release of volatile substances

The invention relates to a fan and an air freshener equipped with the impeller according to the invention for continuous and, if necessary, increased release of volatile substances in the environment of the fan or air freshener wherein the fan electrically or mechanically driven and consists wholly or partly of a carrier material contained at least one volatile substance.

State of the art

Air fresheners are well known in the art. For example, there are air fresheners that cause a permanent scenting of the surrounding space, such as scented candles, fragrance gels, liquid fragrances that are released continuously via delivery means such as wick systems or heat-induced evaporation.

On the other hand, perfume dispensing systems are known, which cause a punctual, caused by the user scenting a room. These include, for example, spray systems based on aerosol cans.

Often, however, both the permanent scenting of a room as well as a punctual, increased release of an ambient air-improving substance is desired. This is the case for example in the toilet area when using a toilet or in the kitchen area to improve the air, for example when roasting fish.

Duftabgevorrichtungen that are suitable for permanent room scenting as well as have a device for the additional delivery of a fragrance are known from the prior art.

For example, EP1076014 discloses a darn perfume dispenser having a first active and a second passive perfume release device independent therefrom. While the second passive fragrance release device provides a substantially permanent fragrance to the environment, targeted actuation of a fragrance can be achieved by the user operating the first fragrance release device. In one embodiment of the invention described in EP1076014, the first active fragrance release device is formed as an aerosol can provided with a spray nozzle on which containers are provided with a fragrance-containing gel. A disadvantage of this design is that by the separate formation of an active and passive perfume dispensing device, such systems have a comparatively large volume of construction and are relatively expensive to manufacture.

Object of the invention

The object of the invention is therefore to provide a compact and inexpensive to produce air freshener for continuous and, if necessary, increased release of volatile substances in the environment.

This object is achieved by an air freshener according to claim 1 and a fan wheel according to claim 28.

fan

For the purposes of this application, a fan wheel rotates about an axis of rotation

Understood rotational body which is suitable to move the surrounding air in motion.

The fan may be formed in particular as Axiallüfterrad, in which the axis of rotation of Axiallüfterrades parallel or axially to the air flow, radial fan, in which the air is sucked in parallel or axially to the drive axis of the radial fan and radially deflected by 90 ° blown or as Tangentiallüfterrad, in the air twice (once from outside to inside and the other way around) by the fan moves, the air once sucked over a large area tangential to the axis of rotation by the fan, deflected by 90 °, taken in the interior again tangential to the axis of rotation, again deflected and in the housing is guided.

The fan wheel usually consists of a hub which serves to receive a shaft for driving the fan wheel and fan blades, which are arranged generally radially to the axis of rotation on the hub.

In a preferred embodiment of the invention, the fan blades with respect to the axis of rotation of the fan at an angle α between 0 ° and 89 °, more preferably between 0 ° and 45 °, whereby an air flow in the radial and / or axial direction relative to the axis of rotation becomes.

Furthermore, it is advantageous that the fan blades are arranged detachably on the fan wheel. This makes it possible to replace the Lüfterradschaufeln, especially when the delivery of volatile substances from the fan blades has exhausted into the environment.

It is preferred that the fan wheel is made of a material that emits volatile substances to the environment. For this purpose, the fan may be wholly or partly made of a material containing volatile substances that are emitted to the environment. In one embodiment of the fan impeller according to the invention, the fan wheel is wholly or partly formed from a polymer containing at least one volatile substance. Alternatively, it is also possible that the fan completely or partially consists of a pulp material that is suitable for receiving and emitting volatile substances.

It can be seen that for the intended use of the fan wheel, at least one fan blade is wholly or partially formed from a material containing at least one volatile substance.

In addition to the above-described embodiment, according to which the fan itself is made of a material that emits volatile substances to the environment, can be fixed in an alternative embodiment of the invention, means for delivering volatile substances to the environment on the fan.

The means for delivering volatile substances to the environment may in one possible embodiment be firmly bonded to the fan wheel, in particular on the surfaces of the fan blade. This can be realized for example in the form of a coating on the surfaces of the fan blade, wherein it is particularly preferred that the coating consists of a gel containing volatile substance.

The coating may have a layer thickness of a few microns to a few centimeters. In particular, the coating may also be multi-layered, so that layers with mutually different carrier materials and / or compositions of volatile substances are arranged one above the other. The fact that, for example, different fragrance compositions are incorporated in the respective layers, time-varying fragrance compositions can be released over the period of use of the fan wheel, whereby, for example, habituation can be prevented or at least reduced.

It is also possible to bond a carrier material for volatile substances by gluing, welding or the like with the fan and in particular with the fan blades.

As an alternative to the cohesive connection, the means for delivering volatile substances to the environment can be positively and / or non-positively fixed to the fan wheel, in particular on, on or in the surfaces of the fan blade. The means for delivering volatile substances to the environment may be releasably or permanently fixed to the fan wheel.

For example, a means for delivering volatile substances to the environment may be formed as a frame in which a fragrance-added gel is fixed, which may be arranged in a corresponding receptacle on or in the fan blade, for example by a snap-in closure , In a further alternative embodiment of the invention, a fan blade has at least one chamber adapted to receive the volatile material in such a way that the carrier materials remain in the chamber while the volatile substances are emitted from the chamber into the environment.

In this case, for example, the openings of the chamber may be closed by a membrane which retains the carrier material in the chamber and is permeable to at least one volatile substance.

In order to at least alleviate unwanted release of volatile substances into the environment prior to first use of the impeller, the support material or chamber may be covered with a removable closure member which may be selected from the group including release liner, tear-off lid, attachment lid, fold lid, groove cover , Hinged lid, sliding lid, snap lid, screw cap, slip lid or plug.

The fan alone or in conjunction with the surrounding housing in the state of rotation can generate acoustic signals, such as whirring or whistling, which can serve as an operating signal for the user.

Träqermaterial

In principle, the carrier materials of the volatile substances can occupy all aggregate states and / or three-dimensional forms that can be realized as a function of the chemical and physical properties of the carrier materials.

In a first preferred embodiment, at least carrier material is present as a liquid.

In a further preferred embodiment of the invention, at least one carrier material of a volatile substance is a gel.

In a further preferred embodiment, at least one support material is present as a solid. With particular preference carrier materials are formed as shaped bodies, in particular as a fan and / or fan blades or parts thereof. Alternatively, the support materials may also be present in particulate form.

In order to realize mutually different release kinetics of volatile substances from the support material, at least two support materials may be different from each other.

The support materials can also generate optical and / or acoustic signals, for example by fluorescence, phosphorescence or bursting of cellular structures. As a result, for example, optical and / or acoustic consumption displays can be realized. polymers

The term "polymers" in the context of the present application polymers,

Polyadducts and polycondensates summarized.

As polymers in this application are referred to such high molecular weight compounds, the structure of which proceeds according to a chain growth mechanism. In the context of the present application, preferred polymers are polyethylene, polypropylene, poly-1-butene, poly-4-methyl-1-pentene, polyvinyl chloride, polyvinylidene chloride, polyacrylonitrile and / or polystyrene.

Polyadducts are formed by polyaddition, that is to say polyreactions in which polymers are formed by repeatedly repeating and mutually independent linking reactions of bis- or polyfunctional reactants (monomers) via reactive oligomers. Preferred polyadducts are polyurethanes.

Like the polyadducts, polycondensates are formed by frequently repeated and mutually independent linking reactions of discrete oligomers and monomers, but in contrast to the polyaddition, there is simultaneously a cleavage of low molecular weight compounds. Preferred polycondensates in the context of the present invention are polyamides, polycarbonates and polyesters.

In summary, the polymeric carrier material contains at least partially polyethylene, polypropylene, polyethylene / polypropylene copolymers, polyether / polyamide block copolymers, styrene / butadiene (block) copolymers, styrene / isoprene (block) copolymers, styrene / ethylene / butylene copolymers , Acrylonitrile / butadiene / styrene copolymers, acrylonitrile / butadiene copolymers, polyether esters, polyisobutene, polyisoprene, ethylene / ethyl acrylate copolymers, polyamides, polycarbonate, polyesters, polyacrylonitrile, polymethyl methacrylate or polyurethanes.

Polymers are characterized by a particular versatility also in terms of their processability. Plastics can be processed by extrusion or injection molding as shaping as by drawing process. When pulling (thermoforming), a preheated plastic plate or foil between the two parts of the tool, the positive and the negative, introduced and then compressed, whereby the plastic part is given its shape. Similarly, the so-called cold deformation runs; Here, however, the plate or film to be deformed is not preheated. If no negative tool is available, it is called deep drawing. In the context of the present invention, the fan wheel and / or the fan blades can be produced by all methods known to the person skilled in the art, in particular by extrusion, injection molding, thermoforming or blow molding. In a preferred embodiment of the invention, the molded parts can allow the fragrance and optional other active ingredients to escape. It is particularly preferred that a polymeric support material has a melting or softening point between 30 and 150 ^° C. and at least one fragrance.

As a polymeric carrier material for volatile substances are generally all polymers or polymer mixtures that meet the above criteria with respect to the melting or softening temperature. Preferred scent delivery systems in the context of the present application are characterized in that the polymeric carrier material comprises at least one substance selected from the group consisting of ethylene / vinyl acetate copolymers, low or high density polyethylene (LDPE, HDPE) or mixtures thereof, polypropylene, polyethylene / polypropylene copolymers, Polyether / polyamide block copolymers, styrene / butadiene (block) copolymers, styrene / isoprene (block) copolymers, styrene / ethylene / butylene copolymers, acrylonitrile / butadiene / styrene copolymers, acrylonitrile / butadiene copolymers, polyetheresters, Polyisobutene, polyisoprene, ethylene / ethyl acrylate copolymers, polyamides, polycarbonate, polyester, polyacrylonitrile, polymethyl methacrylate, polyurethanes, polyvinyl alcohols.

Polyethylene (PE) is a collective name for polymers belonging to the polyolefins with groupings of the type

CH ₂ -CH ₂

as a characteristic basic unit of the polymer chain. Polyethylenes are usually prepared by polymerization of ethylene by two fundamentally different methods, the high pressure and the low pressure process. The resulting products are accordingly often referred to as high pressure polyethylenes and low pressure polyethylenes, respectively; they differ mainly in their degree of branching and, consequently, in their degree of crystallinity and their density. Both methods can be carried out as solution polymerization, emulsion polymerization or gas phase polymerization.

In the high-pressure process branched low density polyethylenes (about 0.915-0.935 g / cm ³ ) and crystal degrees of inertness of about 40-50% are obtained, which are referred to as LDPE types (low density polyethylene). Products with a higher molecular weight and the resulting improved strength and ductility have the abbreviation HMW-LDPE (HMW = high molecular weight). By copolymerizing the ethylene with longer-chain olefins, in particular with butene and octene, the pronounced degree of branching of the polyethylenes produced in the high-pressure process can be reduced; the copolymers have the abbreviation LLD-PE (linear low density polyethylene).

The macromolecules of the polyethylenes from low-pressure process are largely linear and unbranched. These polyethylenes, abbreviated to HDPE (from E high density polyethylene) have degrees of crystallinity of 60-80% and a density of about 0.94-0.965 g / cm3. They are referred to as high or ultra high molecular weight products (about 200,000-5,000,000 g / mol or 3,000,000-6,000,000 g / mol) under the abbreviation HD-HMW-PE or UHMW-HD-PE are offered. Also, medium density (MDPE) products from blends of low and high density polyethylenes are commercially available. Linear polyethylenes with densities <0.918 g / cm3 (VLD-PE, from E very low density polyethylene) are only slowly gaining market significance.

Polyethylenes have a very low permeability to water vapor, the diffusion of gases and of aromatic substances and ethereal substances by polyethylenes is relatively high. The mechanical properties are strongly dependent on the molecular size and structure of the polyethylenes. In general, the degree of crystallinity and density of polyethylenes increase with decreasing degree of branching and with shortening of the side chains. With the density increase shear modulus, hardness, yield strength and melting range; it decreases: shock resistance, transparency, swellability and solubility. With the same density increase with increasing molecular weight of the polyethylene tear strength, elongation, shock resistance, impact resistance and creep strength. Depending on the method of operation in the polymerization, products with paraffin wax-like properties (MR around 2000) and products with highest toughness (MR over 1 million) can be obtained.

The processing of the polyethylene types can be carried out according to all methods customary for thermoplastics.

Polypropylene (PP) is the name for thermoplastic polymers of propylene with the general.

Formula:

- (CH ₂ -CH [CH 3]) _n -

The basis for the polypropylene production was the development of the process for the stereospecific polymerization of propylene in the gas phase or in suspension by Natta. This is initiated with Ziegler-Natta catalysts, but increasingly also by metallocene catalysts and leads either to highly crystalline isotactic or less crystalline syndiotactic or amorphous atactic polypropylenes.

Polypropylene is characterized by high hardness, resilience, stiffness and heat resistance. Short-term heating of polypropylene articles is even possible up to 140 ^° C. At temperatures below 0 ^° C., some embrittlement of the polypropylenes occurs, which, however, can be shifted to much lower temperature ranges by copolymerization of the propylene with ethylene (EPM, EPDM). In general, the impact resistance of polypropylene can be improved by modification with elastomers. The chemical resistance is good as with all polyolefins. An improvement in the mechanical properties of the polypropylene is achieved by reinforcement with talc, chalk, wood flour or glass fibers. Polypropylenes are even more sensitive to oxidation and light than PE, which is why the addition of stabilizers (antioxidants, light stabilizers, UV absorbers) is required. Polyether is a generic term in the field of macromolecular chemistry for polymers whose organic repeating units are held together by ether functionalities (COC). According to this definition, a large number of structurally very different polymers belong to the polyethers, eg. As the polyalkylene glycols (polyethylene glycols, polypropylene glycols and polyepichlorohydrins) as polymers of 1, 2-epoxides, epoxy resins, polytetrahydrofurans (polytetramethylene glycols), polyoxetanes, polyphenylene ethers (see polyarylethers) or polyetheretherketones (see. Polymers with pendant ether groups, such as the cellulose ethers, starch ethers and vinyl ether polymers, are not included among the polyethers.

The group of polyethers also includes functionalized polyethers, d. H. Compounds having a polyether backbone laterally attached to their backbones still carry other functional groups, e.g. As carboxy, epoxy, AIIyI or amino groups, etc. are widely used block copolymers of polyethers and polyamides (so-called polyetheramides or polyether block amides, PEBA).

Polyamides (PA) are polymers whose basic building blocks are held together by amide bonds (-NH-CO-). Naturally occurring polyamides are peptides, polypeptides and proteins (Ex .: protein, wool, silk). The synthetic polyamides, with a few exceptions, are thermoplastic, chain-like polymers, some of which have attained great industrial importance as synthetic fibers and materials. According to the chemical structure, the so-called homo-polyamides can be divided into two groups, the aminocarboxylic acid types (AS) and the diamine-dicarboxylic acid types (AA-SS, where A denotes amino groups and S denotes carboxy groups). The former are made of only a single monomer by z. B. polycondensation of a ω-aminocarboxylic acid (1) (polyamino acids) or by ring-opening polymerization of cyclic amides (lactams) (2).

In addition to the homopolyamides, some co-polyamides have gained importance. It is customary in these a qualitative and quantitative indication of the composition z. B. PA 66/6 (80:20) for from 1, 6-hexanediamine, adipic acid and ε-caprolactam in the molar ratio 80:80:20 prepared polyamides.

Because of their special properties, polyamides which contain exclusively aromatic radicals (for example those of p-phenylenediamine and terephthalic acid) are classified under the generic name. Aramids or polyaramides summarized (Ex .: Nomex®).

The most commonly used polyamide types (especially PA 6 and PA 66) consist of unbranched chains with average molecular weights of 15,000 to 50,000 g / mol. They are partially crystalline in the solid state and have degrees of crystallization of 30-60%. An exception are polyamides of building blocks with side chains or co-polyamides of very different components, which are largely amorphous. In contrast to the generally milky-opaque, semi-crystalline polyamides these are almost crystal clear. The softening temperature of the most common homo-polyamides are between 200 and 260 ⁰ C (PA 6: 215-220 ⁰ C, PA 66: 255-260 ⁰ C). Polyester is the collective name for polymers whose basic building blocks are held together by ester bonds (- CO-O-). According to their chemical structure, the so-called homopolyesters can be divided into two groups, the hydroxycarboxylic acid types (AB-polyester) and the dihydroxy-dicarboxylic acid types (AA-BB-polyester). The former are made of only a single monomer by z. B. polycondensation of a ω-hydroxycarboxylic acid 1 or by ring-opening polymerization of cyclic esters (lactones) 2 produced.

Branched and crosslinked polyesters are obtained in the polycondensation of trihydric or polyhydric alcohols with polyfunctional carboxylic acids. The polyesters are generally also the polycarbonates (carbonic acid polyester) counted.

AB type polyesters (I) are u. a. Polyglycolic acids, polylactic acids, polyhydroxybutyric acid [poly (3-hydroxybutyric acid), poly (ε-caprolactone) s and polyhydroxybenzoic acids.

Pure aliphatic AA-BB type polyesters (II) are polycondensates of aliphatic diols and dicarboxylic acids, the u. a. as hydroxy terminated products (as polydiols) for the preparation of polyester polyurethanes [e.g. B. polytetramethylene adipate]. The most technically significant in terms of quantity are AA-BB type polyesters of aliphatic diols and aromatic dicarboxylic acids, in particular the polyalkylene terephthalates, with polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and poly (1,4-cyclohexanedimethylene terephthalate) s (PCDT) as the most important representatives , These types of polyesters can be widely varied in their properties by using other aromatic dicarboxylic acids (for example isophthalic acid) or by using diol mixtures in polycondensation and can be adapted to different fields of application.

Purely aromatic polyesters are the polyarylates to which u. a. which include poly (4-hydroxybenzoic acid). In addition to the previously mentioned saturated polyesters, it is also possible to prepare unsaturated polyesters from unsaturated dicarboxylic acids which have acquired industrial significance as polyester resins, in particular as unsaturated polyester resins (UP resins).

Polyesters are usually thermoplastics. Products based on aromatic dicarboxylic acids have pronounced material character. The purely aromatic polyarylates are characterized by high thermal stability.

Polyurethanes (PU) are polymers in whose macromolecules the repeat units are linked by urethane groups -NH-CO-O-. Polyurethanes are generally obtained by polyaddition from dihydric or higher alcohols and isocyanates. Depending on the choice and stoichiometric ratio of the starting materials so arise polyurethanes with very different mechanical properties, which are used as components of adhesives and paints (polyurethane resins), as ionomers, as a thermoplastic material for bearing parts, rollers, tires, rollers and as more or less hard elastomers in fiber form (elastofibres, short PUE for these elastane or spandex fibers) or as polyether or polyester urethane rubber (EU or AU)

Polyurethane foams are formed in the polyaddition, when water and / or carboxylic acids are present, because these react with the isocyanates with elimination of the uplifting and foaming carbon dioxide. With polyalkylene glycol ethers as diols and water as the reaction component, flexible polyurethane foams are obtained, with polyols and blowing gases from CFCs (especially R 11), rigid polyurethane foams and structural or integral foams are obtained. Additionally required auxiliaries are here z. As catalysts, emulsifiers, foam stabilizers (especially polysiloxane-polyether copolymers), pigments, aging and flame retardants. In the 1970s, the so-called RIM technique was developed for the manufacture of complexly shaped objects made of polyurethane foam (reaction injection molding). The RIM-Verf. is due to rapid dosing and mixing of the components, injection of the reactive mixture into the mold and rapid curing; the cycle time is only a few minutes. Using RIM technology u. a. Car body parts, shoe soles, window profiles and television housing generated.

Polyvinyl alcohols (PVAL, occasionally also PVOH) is the term for polymers of the general structure

CH ₂ -CH-CH ₂ -CH-

OH OH

in small proportions (about 2%) also structural units of the type

- CH ₂ -CH-CH-CH ₂ --OH OH

contain.

Commercially available polyvinyl alcohols are available as white-yellowish powders or granules with degrees of polymerization in the range of about 100 to 2500 (molar masses of about 4000 to 100,000 g / mol). The polyvinyl alcohols are characterized by the manufacturer by indicating the degree of polymerization of the starting polymer, the degree of hydrolysis, the saponification number or the solution viscosity. Depending on the degree of hydrolysis, polyvinyl alcohols are soluble in water and a few highly polar organic solvents (formamide, dimethylformamide, dimethyl sulfoxide); They are not attacked by (chlorinated) hydrocarbons, esters, fats and oils. Polyvinyl alcohols are classified as toxicologically safe and are biologically at least partially degradable. The water solubility can be reduced by aftertreatment with aldehydes (acetalization), by complexation with Ni or Cu salts or by treatment with dichromates, boric acid or borax. The coatings of polyvinyl alcohol are largely impermeable to gases such as oxygen, nitrogen, helium, hydrogen, carbon dioxide, but allow water vapor to pass through.

In a particularly preferred embodiment of the present invention, the polymeric carrier material for volatile substances consists at least partly of ethylene / vinyl acetate copolymer. A further preferred subject of the present application is therefore a scent delivery system or impeller, characterized in that the polymeric carrier material at least 10 wt .-%, preferably at least 30 wt .-%, particularly preferably at least 70 wt .-% ethylene / vinyl acetate copolymer contains, preferably completely made of ethylene / vinyl acetate copolymer.

Ethylene / vinyl acetate copolymers is the name for Copoylmere of ethylene and vinyl acetate. The preparation of this polymer is basically carried out in a process similar to that of the production of low density polyethylene (LDPE). With an increasing proportion of vinyl acetate, the crystallinity of the polyethylene is interrupted and in this way the melting and softening points or the hardness of the resulting products are reduced. The vinyl acetate also makes the copolymer more polar and thus improves its adhesion to polar substrates.

The ethylene / vinyl acetate copolymers described above are widely available commercially, for example under the tradename Elvax ^® (Dupont). In the present invention, particularly suitable polyvinyl alcohols are, for example Elvax ^® 265, Elvax ^® 240, Elvax ^® 205W, Elvax ® 200W, as well as Elvax ^® 360th

Some particularly suitable copolymers and their physical properties are shown in the following table:

In one embodiment, the scent delivery system or the fan wheel according to the invention may contain a polymeric carrier material for highly volatile substances in the form of particles, it being possible for the particles to be located, in particular, in throughflow chambers of the fan wheel blades.

The spatial form of these particles is limited only by the technical possibilities in their production. As a spatial form come thus all reasonable manageable configurations into consideration, for example, so cubes, cuboids and corresponding space elements with flat side surfaces and in particular cylindrical configurations with a circular or oval cross-section. This last embodiment comprises tablet-shaped particles up to compact cylinder pieces with a height-to-diameter ratio above 1. Further possible spatial forms are spheres, hemispheres or "elongated spheres" in the form of ellipsoidal capsules as well as regular polyhedra, for example tetrahedron, hexahedron, octahedron, Dodecahedron, icosahedron. It is also conceivable star-shaped formations with three, four, five, six or more tips or completely irregular body, which may be designed, for example, motivic. Depending on the field of application of the agents according to the invention, suitable motifs are, for example, animal figures, such as dogs, horses or birds, floral motifs or the representation of fruits. The motivic design can also refer to inanimate objects such as vehicles, tools, household items or clothing.

Owing to the numerous design possibilities for the particles, the agents according to the invention are distinguished not only by advantages in their preparation. Due to the various forms of the perfume-containing particles are also visually clearly perceptible to the consumer and allow through the targeted spatial design of these particles for product acceptance particularly advantageous visualization of the fragrances contained in the compositions of the invention or other optional active substances contained in these agents. Thus, for example, the different modes of action of individual active substances can be clarified by the visually perceptible multiphase of these agents.

In the context of the present application, particles are summarized as particles which have a solid, ie dimensionally stable, non-flowable consistency which is solid at room temperature. Preferred particles have a mean diameter of 0.2 to 20 mm, preferably from 0.5 to 5 mm and in particular from 0.5 to 3.5 mm.

The preparation of the polymeric support materials to the particles described above can be carried out on all the skilled person for processing these substances known methods. In the context of the present invention, extrusion is preferably preferred by injection molding and spraying into polymer granules.

dyes

Particularly preferred are carrier materials for volatile substances which are colored. By coloring at least one of the support materials, an optical differentiation of this material can be achieved and the multiple benefits of these different compositions can be illustrated in a simple manner. Furthermore, the dyes are also suitable as an indicator, in particular as a consumption indicator for the colored active ingredient compositions.

When choosing the colorant, it must be taken into account that the colorants have a high storage stability and insensitivity to light. At the same time, it should also be taken into account when choosing suitable colorants that colorants have different stabilities to the oxidation. In general, water-insoluble colorants are more stable to oxidation than water-soluble colorants. Depending on the solubility and thus also on the sensitivity to oxidation, the concentration of the colorant varies. In the case of readily water-soluble colorants, colorant concentrations in the range of a few 10 ^-2 to 10 ³ % by weight are typically selected. In the due to their brilliance, particularly preferred, but are less readily water-soluble pigment dyestuffs, however, the appropriate concentration of the colorant is typically a few 10 ³ to 10 ^"4 wt .-%.

In a preferred embodiment, the dye additionally has an indicator function in addition to its aesthetic effect. As a result, the consumer of the current state of consumption of the fragrance is displayed so that he receives in addition to the lack of fragrance impression, which may for example be based on a habituation effect on the part of the user, another reliable indication when the fragrance dispensing system is replaced by a new one.

The indicator effect can be achieved in various ways: In particular, a dye can be used, which escapes from the particles during the period of application. Also, a color change may be caused, for example, by chemical reactions or by decomposition.

Volatile substances

A volatile substance may be selected from the group of fragrances, antimicrobial agents, germicides, fungicides, air freshening substances, substances for the destruction of bad smells, medically acting, inhalable substances, in particular also substances for mood stimulation. According to a preferred embodiment of the invention, at least two volatile substances of the fan are different from each other.

These mutually different volatile substances may be arranged spatially separated from each other on the fan, for example in such a way that a first substance on a first fan blades and a second substance on a second fan blade is arranged.

However, it is also conceivable that the mutually different substances are arranged next to each other, for example in the form of layers in the carrier material.

In particular, according to a preferred embodiment of the invention, it may be advantageous to provide a delivery of volatile substances in two or more phases. This is advantageous, in particular, when the two phases to be delivered are not stable in storage together or, in the case of dispensing fragrance, an olfactometric adaptation to the dispensed fragrance is to be avoided.

fragrances

Fragrance dispensing systems according to the invention comprise, in addition to a container, fragrance-containing particles based on polymeric carrier materials, the weight fraction of the fragrance (s), based on the total weight of the particles, preferably from 1 to 70% by weight, preferably from 10 to 60% by weight, particularly preferably 20 to 50 wt .-%, in particular 30 to 40 wt .-%, is.

As perfume oils or fragrances, individual fragrance compounds, for example the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons, can be used in the context of the present invention. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethylmethylphenyl glycinate, allylcyclohexyl propionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether, to the aldehydes, for example, the linear alkanals with 8-18 C atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, LiNaI and Bourgeonal, to the ketones, for example, the Jonone, oc-lsomethylionon and methyl cedrylketone , the alcohols include anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol, the hydrocarbons mainly include the terpenes such as limonene and pinene. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance. Such perfume oils may also contain natural fragrance mixtures as are available from vegetable sources, eg pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Muskateller, sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon oil, lime blossom oil, juniper berry oil, Vetiver oil, Olibanum oil, Galbanum oil and Labdanum oil, as well as orange blossom oil, neroliol, orange peel oil and sandalwood oil.

The general description of the perfumes that can be used (see above) generally represents the different substance classes of fragrances. To be perceptible, a fragrance must be volatile, whereby besides the nature of the functional groups and the structure of the chemical compound, the molecular weight also plays an important role plays. For example, most odorants have molecular weights up to about 200 daltons, while molecular weights of 300 daltons and above are more of an exception. Due to the different volatility of fragrances, the smell of a perfume or fragrance composed of several fragrances changes during evaporation, whereby the odor impressions in "top note", "middle note" or "body note" ) and "base note" (end note or dry out). Since odor perception is also largely due to odor intensity, the top note of a perfume does not consist solely of volatile compounds, while the base note is largely made up of less volatile, i. adherent fragrances. For example, in the composition of perfumes, more volatile fragrances can be bound to certain fixatives, preventing them from evaporating too quickly. In the subsequent classification of the fragrances in "more volatile" or "adherent" fragrances so nothing about the olfactory impression and whether the corresponding fragrance is perceived as a head or middle note, nothing said.

By means of a suitable selection of said fragrances or perfume oils, the product smell can be influenced in this way for agents according to the invention immediately upon opening the brand-new composition as well as the use fragrance, for example when used in a dishwashing machine. These fragrance impressions can of course be the same, but can also differ. For the latter odor impression, the use of adhesive odoriferous substances is advantageous, while also more volatile odoriferous substances can be used for product scenting. Adhesion-resistant fragrances which can be used in the context of the present invention are, for example, the essential oils such as angelica root oil, aniseed oil, arnica blossom oil, basil oil, bay oil, bergamot oil, Champacablütenöl, Edel fir oil, Edeltannenzapfen oil, Elemiöl, eucalyptus oil, fennel oil, spruce needle oil, galbanum oil, geranium oil, ginger grass oil, Guaiac wood oil, gurdy balm oil, helichrysum oil, ho oil, ginger oil, iris oil, cajeput oil, calamus oil, chamomile oil, camphor oil, kanaga oil, cardamom oil, cassia oil, pine oil, copaϊva balsam oil, coriander oil, spearmint oil, caraway oil, cumin oil, lavender oil, lemongrass oil, lime oil, tangerine oil, lemon balm oil, Musk Grain Oil, Myrrh Oil, Clove Oil, Neroliol, Niaouli Oil, Olibanum Oil, Orange Oil, Origanum Oil, Palmarosa Oil, Patchouli Oil, Peru Balsam Oil, Petitgrain Oil, Pepper Oil, Peppermint Oil, Pimento Oil, Pine Oil, Rose Oil, Rosemary Oil, Sandalwood Oil, Celery Oil, Spik Oil, Star Aniseed Oil, Turpentine Oil, Thuja Oil, Thyme oil, Verbe oil, vetiver oil, juniper berry oil, wormwood oil, wintergreen oil, ylang-ylang oil, hyssop oil, cinnamon oil, cinnamon oil, citronella oil, lemon oil and cypress oil. But also the higher-boiling or solid fragrances of natural or synthetic origin can be used in the context of the present invention as adherent fragrances or fragrance mixtures, ie fragrances. These compounds include the compounds listed below and mixtures thereof: Ambrettolide, α-amylcinnamaldehyde, anethole, anisaldehyde, anisalcohol, anisole, methyl anthranilate, acetophenone, benzylacetone, benzaldehyde, ethyl benzoate, benzophenone, benzyl alcohol, benzyl acetate, benzyl benzoate, benzyl formate, benzyl valerate, borneol, bornyl acetate, α-bromostyrene, n-decyl aldehyde, n- Dodecyl aldehyde, eugenol, eugenol methyl ether, eucalyptol, farnesol, fenchone, fenchyl acetate, geranyl acetate, geranyl formate, heliotropin, hepticarboxylic acid methyl ester, heptaldehyde, hydroquinone dimethyl ether, hydroxycinnamaldehyde, hydroxycinnamyl alcohol, indole, iron, isoeugenol, isoeugenol methyl ether, isosafrole, jasmon, camphor, Karvakrol, Karvon, p-cresol methyl ether, coumarin, p-methoxyacetophenone, methyl-n-amyl ketone, methyl anthranilic acid methyl ester, p-methylacetophenone, methylchavikole, p-methylquinoline, methyl-β-naphthyl ketone, methyl-n-nonylacetaldehyde, methyl n-nonyl ketone, Muskon, β- Naphthol ethyl ether, β-naphthol methyl ether, nerol, nitrobenzene, n-nonyl aldehyde, nonyl alcohol, n-Oc tylaldehyde, p-oxy-acetophenone, pentadecanolide, β-phenylethyl alcohol, phenylacetaldehyde dimethyacetal, phenylacetic acid, pulegone, safrole, salicylic acid isoamyl ester, salicylic acid methyl ester, salicylic acid hexyl ester, cyclohexyl salicylate, santalol, skatole, terpineol, thymine, thymol, γ-undelactone, vaniline, veratrum aldehyde, Cinnamaldehyde, cinnamyl alcohol, cinnamic acid, cinnamic acid ethyl ester, cinnamic acid benzyl ester. The more volatile fragrances include in particular the lower-boiling fragrances of natural or synthetic origin, which can be used alone or in mixtures. Examples of more readily volatile fragrances are alkyl isothiocyanates (alkyl mustard oils), butanedione, limonene, linalool, linayl acetate and propionate, menthol, menthone, methyl-n-heptenone, phellandrene, phenylacetaldehyde, terpinyl acetate, citral, citronellal.

Preferably, the plastic particles are loaded at a temperature of 15 to 30 ⁰ C, preferably from 20 to 25 ° C, with the selected perfume. For this purpose, the particles are mixed with the appropriate amount of perfume and mixed. In any case, the temperature should be below the melting or decomposition temperature of the plastic and also below the flash point of the perfume oil. The fragrance is absorbed by adhesion, diffusion and / or capillary forces of the polymeric carrier material or of other perfume carrier materials contained in the particle, these being able to swell slightly in the course of this process.

Antimicrobial agents, germicides, fungicides

Further preferred constituents of compositions according to the invention are substances such as antimicrobial agents, germicides, fungicides, antioxidants or corrosion inhibitors, with the aid of which additional benefits, such as, for example, disinfection or corrosion protection, can be realized.

For controlling microorganisms, the compositions of the invention may contain antimicrobial agents. Depending on the antimicrobial spectrum and mechanism of action, a distinction is made between bacteriostatic agents and bactericides, fungistatics and fungicides, etc. Important substances from these groups are, for example, benzalkonium chlorides, alkylaryl sulfonates, halophenols and phenol mercuriacetate. Odor neutralizing and deodorizing active substances

Deodorant action in the context of this application is understood to mean the attenuation or complete eradication of unwanted odors.

From the prior art, a variety of means are known which have a deodorizing effect and which are suitable for use in the impeller according to the invention.

For example, cyclodextrin is known as an odor-absorbing agent, which, however, has proven to be disadvantageous because cyclodextrins only absorb reversible odors reversibly. With access of water and / or temperature changes, these malodors are therefore released over a longer period of time, released again and thus provide the consumer with a discomfort. In addition, only cyclodextrin as an odor absorber containing agents do not lead to a sustained odor absorption.

As deodorizing agents it is also possible to use one or more metal salts of an unbranched or branched, unsaturated or saturated, mono- or polyhydroxylated fatty acid having at least 16 carbon atoms and / or one rosin acid. Alkali metal salts of the abovementioned fatty acids or resin acids are not suitable in the context of the present invention, since they have no deodorizing action.

Another agent for odor neutralization is activated carbon or zeolites, which adsorptively bind unwanted odors to their surfaces. By adjusting certain pore sizes and pore size distributions, certain substances or substance groups can be removed from the ambient air by these adsorbents and bound to their surface.

The agents for odor neutralization may be bound to or on carrier substances.

Suitable carrier substances are generally large-surface materials. In particular, those materials are suitable which can absorb the solution comprising the deodorizing agent without this solution flowing away from the carrier as a liquid and permitting the solution containing the deodorizing agent to pass to the surface of the carrier by capillary action where appropriate and evaporating there or evaporates. Optionally, the support surface may be perforated to allow additional liquid leakage in the form of vapor.

Preferably, the carrier comprises clays; Ceramics, polymers, preferably sintered polymers, more preferably sintered polyethylene; Textile composites, preferably nonwovens; Papers, for example cardboard; Molecular sieves or zeolites and / or mixtures of the abovementioned materials. Further conceivable carrier materials are silicates, porous glass, ion exchange resins, Dextrans, as well as cellulose, in particular crimped cellulose. Most preferably, the carrier comprises Sorbarod®.

Further, the carrier enables the deodorizing agent to be mounted in the space to be deodorized without causing direct contact between the liquid and objects in the space to be deodorized. This avoids that residues are left by non-evaporating or vaporizing ingredients of the deodorizing agent on objects or surfaces, especially on textile materials.

The deodorizing agents may be substantially firmly bonded to the support material or may be emitted as a volatile substance from the support material into the environment.

The deodorizing means may be arranged at any suitable location of the fan or the air freshener. It is particularly preferred to arrange the deodorizing means on the blades of the fan wheel.

drive mechanism

The drive mechanism may include an electrical energy source coupled to a motor, wherein the actuator closes and / or opens the circuit between the power source and the motor and the motor is coupled to the fan wheel such that the drive motion of the motor causes rotational movement of the motor Fan wheel (4, 5, 5a, 5b, 5c, 5d) causes.

The drive mechanism can also be designed purely mechanically, that is to say without an electrical energy source.

In an advantageous embodiment of the invention, the drive mechanism transforms a translational movement of the actuating element into a rotational movement of the fan wheel.

According to an alternative embodiment, the drive mechanism can also transmit a rotational movement of the actuating element into a rotational movement of the fan wheel, wherein the rotational speed of the actuating element and the fan wheel can be of different sizes.

Furthermore, it is advantageous if the drive mechanism comprises a means for at least partial storage of kinetic energy of the actuating element. The means for at least partially storing kinetic energy of the actuating element can be configured in particular in such a way that energy is transmitted to the fan wheel after actuation of the actuating element and a rotational movement of the fan wheel is effected. The means for at least partially storing kinetic energy of the actuating element may in particular be a memory spring. LIST OF REFERENCES

Fig. 6 shows the air freshener attached to a toilet bowl Figure 1 shows the air freshener according to the invention in the assembled state. The air freshener consists of a housing 1, which is formed from the upper housing shell 1a and the lower housing shell 1 b. The dome-shaped housing shells 1a and 1b have a plurality of openings 6 in their surface. From a central recess of the housing upper shell 1a protrudes the cylindrical actuator 2, which can be actuated by pressing.

FIG. 2 shows the air freshener known from FIG. 1 in an exploded view, so that the individual components of the air freshener become visible. Inside the housing 1, which is formed from the upper housing shell 1a and the lower housing shell 1 b, there are the drive mechanism 3 and the fan 4. The upper housing shell 1a and the lower housing shell 1 b can force and / or positive and / or cohesive with each other be connected. It may be advantageous to choose a releasable connection between the housing shells to allow replacement of the fan 4. For this purpose, for example, the upper housing shell 1a and the lower housing shell 1b can be releasably connected together by means of a screw cap or a snap-in closure.

As can be seen from FIG. 2, a further shell element 7 can be arranged above the housing upper shell 1a. The shell element 7 also has a plurality of openings. By turning the housing upper shell 1a relative to the shell element 7, the openings 6 of the housing upper shell 1a can be closed, partially opened or completely opened. As a result, a control of the release rate of volatile substances from the air freshener is possible.

Within the housing 1, the drive mechanism 3 is arranged. This consists in the illustrated embodiment of the coil spring 3a, in the interior of the drive shaft 3b is arranged. On the bottom side, the spring 3 a is inserted into the hub 8 of the fan wheel 4. At the head end, the spring 3a is supported against the actuating element 2. This arrangement essentially corresponds to a s.g. Brummel gyro mechanism, as used for example in gyroscopes application. This mechanism 3 converts the translational downward movement generated during the actuation of the actuating element 2 into a rotary drive movement of the fan wheel 4.

The fan 4 itself is formed as an axial fan with the fan blades 5a, 5b, 5c and 5d. A detailed view of the fan wheel 4 is shown in FIG. 3.

It can be seen that on the Lüfterradschaufeln 5 a carrier material 9 is applied for volatile substances. By way of example, some possible embodiments of how a carrier material can be connected to a fan blade 5 are shown below. For this purpose, a cross section along the line BB shown in Figure 3 is considered. FIG. 4a shows a cross-section of the fan wheel 4 with a coating on the impeller blade 5. The coating 9 can be applied to the impeller blade 5 in a materially bonded manner. However, it is also conceivable not to apply the carrier material 9 as a coating on the fan blade 5, but stick to the fan blade 5 cohesively as a prefabricated block. For this purpose, the carrier material 9, in particular as a gel, be formed.

In a further development of the device known from FIG. 4 a, a cross-section of the fan wheel 4 with a multiphase carrier material in the vertical direction can be seen in FIG. 4 b. It can be seen that a second carrier material layer 9b is arranged above a first carrier material layer 9a. In particular, different fragrances can be introduced into these different carrier material layers. It is also conceivable to form layers with different volatile substances in a carrier material in the vertical direction. Both embodiments have the goal to produce a variable over time fragrance perception, thus, for example, to avoid adaptation effects such as habituation or at least reduce.

In principle, it is also conceivable that the different carrier materials are not formed as shown in Figure 4b, in the vertical direction of multi-phase, but as shown in Figure 4c, are arranged alternately in the horizontal direction.

In addition to the embodiments shown in FIGS. 4a to 4c in which one or more carrier materials 9 are applied directly to a fan blade 5 or are connected directly to the fan blade 5, it is also possible to contact the carrier materials by means of a receptacle 10 to introduce a fan blade. This will be explained in more detail with reference to the following drawings:

FIG. 4d shows a trough-shaped receiving element 10 in which the carrier material 9 is arranged. The receiving element 10 is material, positive or non-positively connected to the Lüfterradschaufel 5. Depending on whether it is desired to form the receptacle 10 as a refill unit, the connection between the refill unit 10 and the fan impeller blade 5 can be made detachable or non-detachable.

The receiving element 10 may also be formed as a frame by the carrier material 9 is arranged. This frame can be introduced into a corresponding opening or recess in or on the fan blade 5. This frame-shaped arrangement has the advantage that the volatile substances can escape from the carrier material 9 via two surfaces. In this embodiment, it is advantageous that the carrier material 9 is gel-like or solid. If a liquid carrier material is to be used, the arrangement shown in FIG. 4f can be used.

The frame 10 has a double T-shaped cross-sectional profile in this embodiment. The bottom and top surfaces are each closed by a membrane 11a and 11b. The Support material 9 is thus enclosed within the chambers bounded by the receptacle and the membrane. The membranes 11a and 11b allow permeation of volatile substances, while the liquid carrier material is retained substantially in the receiving element. As in the embodiment already known from FIGS. 4d and 4e, the receptacle 10 is also detachably arranged in a corresponding opening or receiving the fan blade 5, in particular in a form-fitting or non-positive manner.

However, it is also conceivable that the Lüfterradschaufel 5 itself forms a chamber for receiving carrier materials 9. Such a configuration is shown in FIG. 4g. A cavity in the interior of the fan blade 5 is completely filled with particulate solid support material 9. About bottom and top openings 12 of this cavity is connected corresponding to the environment. As a result, volatile substances can be emitted from the carrier material into the environment. The openings 12 and the carrier material 9 are configured in such a way that an exit of the carrier materials 9 through the openings 12 is prevented.

FIG. 5 shows the arrangement of the fan blades with respect to the axis of rotation of the fan wheel 4. The Lüfterradschaufeln 5 may be inclined relative to the axis of rotation R at an angle α. Depending on the angle of inclination α, a stronger or weaker axial or radial air flow is generated. At an angle of inclination α of 0 ° degrees with respect to the axis of rotation R, substantially a complete radial air flow is generated. At an angle α of 45 ° degrees, however, the axial flow component of the air movement is greatest.

Depending on the field of application, it is thus possible to produce rather narrow emission maps by a substantially purely axial air movement or, a wide range of emissions by a predominantly radial flow direction of the flow generated by the fan.

Figure 6 shows an assembled air freshener with a holder 14 which fixes the air freshener at the edge of a toilet bowl 13. Of course, it is also conceivable to attach the air freshener with other support elements, for example, to doors, shower cubicles, dustbin lids, automotive dashboards, or the like.
