Description

Abschabevorrichtunq for volatile substances

The invention relates to a volatile substance delivery device.

State of the art

A wide variety of prior art scent dispensers are known.

For example, perfume-impregnated pulp molded articles (so-called "miracle trees"), which provide a permanent scent of the environment until complete release of the fragrance, are unsuitable for providing fragrance samples in showrooms, however, in order to provide lasting scenting of the environment which are usually a plurality of fragrance samples for different products to provide.

Perfume dispensers are also well known in the art but have disadvantages for use in retail premises. The usually liquid carrier material from such perfume dispenser is applied to a paper strip, which is then thrown away, which should be avoided for environmental reasons. Furthermore, the correct fragrance impression develops only after the volatile alcohol carrier components are vaporized.

Even with perfume impregnated papers and sealed by a rub-off layer papers are unsuitable for a fragrance presentation of products, especially in showrooms, as a repeated release is not possible. Such fragrance presentation papers are designed for single use only.

Object of the invention

The object of the invention is to provide a volatile substance release device which is easy to manufacture and to handle and which releases only volatile substances into the environment, if desired by the user.

This object is achieved by a fragrance dispensing device according to claim 1 and a fragrance presentation system according to claim 27. Container

The container of the fragrance dispenser is substantially dimensionally stable and has flexible walls. The walls are formed in such a way that they can be squeezed by the hand of a user.

The container may be formed as a bottle, tube, cup or the like.

It is particularly advantageous to design the container in the shape of a pencil, so that it can be enclosed by the hand of a user.

The container has a container opening. It is advantageous that the container opening is formed in such a way that the carrier materials can not pass through the opening.

Preferably, the container is at least partially transparent, so that, for example, the consumption of a volatile substance is detectable by means of a decolorization of the carrier material from the outside by the user.

In a further advantageous embodiment of the invention, the container is refillable, i. that the container can be opened and the used carrier material can be removed in order to then fill it with "fresh", loaded carrier material.

The container is preferably made of a plastic and can take any spatial form. Particularly preferred is a cylindrical space shape. In particular, to be preferred is a pin-shaped design of the container.

silicone valve

In the container opening of the container, a silicone valve is arranged, which is made of an elastic silicone material and completely covers the container opening, plate-like or lid-like.

The silicone valve has at least one incision, wherein the incision widens in the presence of a defined internal pressure in the container and closes when falling below this internal pressure.

Preferably, the silicone valve has an X-shaped notch.

In the rest position of the valve, leakage of laden air from inside the container is prevented. The valve and the carrier material are configured in such a way that leakage of carrier material from the valve is prevented. In the case of a solid carrier material, this can be realized, for example, in that the opening of the valve is smaller than the carrier material, so that it can not pass through the valve opening.

This also ensures that a user - especially children - can not come into direct contact with the substrate.

Träqermaterial

The volatile carrier material may be a solid, gel or liquid.

In particular, the carrier material may be a solid based on a polymer. However, it is also conceivable to use other solid support materials known in the art, such as pulp-based materials, sponges and the like.

In a further alternative, the carrier material is a liquid or a gel. This is recorded, for example, in a closed container with a permeable membrane. The membrane is designed such that a volatile substance, such as a fragrance or other active substances, pass through the membrane, but not the carrier material.

polymers

The term "polymers" are used 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. - A -

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.

It is particularly preferred which comprises a polymeric carrier material has a melting or softening point between 30 and 150 ⁰ C as well as at least one fragrance is.

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

CH2 - OH2

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.

When high-pressure method branched low density polyethylenes fall designated and crystallinity of about 40-50%, which is as LDPE-type (low density polyethylene) (cm ³ approximately 0,915- 0,935 g /). 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 products with high or ultra-high molar mass (about 200 000-5 000 000 g / mol or 3 000 000-6 000 000 g / mol) under the short name HD-HMW-PE or UHMW-HD-PE 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 term used in the field of macromolecular chemistry for polymers whose organic repeat units are held together by ether functionalities (C-O-C). 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 polyarylether) or polyetheretherketones (see. Not to the polyethers polymers with pendant ether groups are calculated, such as. a. the cellulose ethers, starch ethers and vinyl ether polymers.

The group of polyethers also include functionalized polyethers, ie compounds having a polyether skeleton, which laterally attached to their main chains still carry other functional groups such. 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). AIs 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 (polyesters of carbonic acid) are calculated:

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 fewer 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 technology 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

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 partially of ethylene / vinyl acetate copolymer. A further preferred subject of the present application is therefore a fragrance delivery system, characterized in that the polymeric carrier material contains at least 10 wt .-%, preferably at least 30 wt .-%, particularly preferably at least 70 wt .-% ethylene / vinyl acetate copolymer, 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 fragrance delivery system 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 In many embodiments, the fragrance-containing particles are also clearly visually perceptible to the consumer and, through the targeted spatial design of these particles, make visualization of the fragrances contained in the agents according to the invention, or other active substances contained in these agents, particularly advantageous for product acceptance possible. Thus, for example, the different modes of action of individual active substances can be clarified by the visually perceptible multiphase of these agents.

As particles in the context of the present application particles are summarized which have a solid at room temperature, that is, dimensionally stable, non-flowable consistency. Preferred particles have an average diameter of from 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 achieved and the multiple benefits of these different

Compositions are easily illustrated. Furthermore, the are suitable

Dyes but also as an indicator, in particular as a consumption indicator for the colored

Drug 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. On the other hand, in the case of the particularly preferred, but less readily water-soluble, pigment dyes due to their brilliance, the suitable concentration of the colorant is typically about 10 ³ to 10 ^-4 % by weight. 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 can be selected from the group of fragrances, antimicrobial agents, germicides, fungicides, air fresheners, substances to destroy bad smells, medically active, inhalable substances, especially substances for mood stimulation and pharmaceutically active substances.

For example, nicotine compounds can also be used as volatile substances. In this way, an application device for nicotine withdrawal can be provided, wherein the application device can be used either periodically and / or in the case of an acute request for nicotine as part of a weaning measure. Many of the risks of tobacco smoke are avoided by nasal inhalation of "pure" nicotine.

Another application example results from the use of, for example, eucalyptus oils, which can cause a swelling of the nasal mucous membranes during application.

fragrances

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

In the context of the present invention, perfume oils or fragrances can be individual perfume compounds, for example the synthetic products of the ester type, ethers, aldehydes, Ketones, alcohols and hydrocarbons are used. 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 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, to the ketones such as the ionone, 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. Also suitable are muscatel, sage, chamomile, clove, lemon balm, mint, cinnamon, lime, juniper, vetiver, olibanum, galbanum and labdanum, and orange blossom, neroliol, orange peel and sandalwood.

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 a suitable selection of said fragrances or perfume oils can be in this way for inventive agent, both the product odor immediately upon opening the brand new agent as well as the fragrance of use are influenced. 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, Neroli Oil, 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, verb ena oil, vetiver oil, juniper berry oil, wormwood oil, wintergreen oil, ylang-ylang oil, hyssop oil, cinnamon oil, cinnamon oil, lemon oil, lemon oil and cypress oil.

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, that is exclusive 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 support materials are silicates, porous glass, ion exchange resins, dextrans, and also 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.

Fig. 1a shows a pen-like perfume dispensing device 1, which is filled with a bed of spherical support material 4 for a volatile substance - preferably a perfume - filled. At the bottom end of the fragrance dispensing device is a substantially circular container opening 5, which is closed with a silicone valve 6. The silicone valve 6 has a centrally arranged X-shaped notch, which can be seen from the detailed illustration of the silicone valve in FIG. 1a. In the resting state of the fragrance dispensing device, the silicone valve 6 is in its closed position, so that no laden air will give off to the environment.

The walls 2 and 3 of the substantially dimensionally stable fragrance dispensing device 1 are formed squeezable, which is indicated by the arrows in the figure. That the walls 2, 3 return to their original position after being squeezed together. The squeezing causes an increased pressure inside the fragrance dispensing device 1, which causes the silicone valve 6 arranged in the container opening 5 to open and air laden with fragrance to move from the fragrance dispenser 1 through the carrier material bed 4 and the container opening 5 into the environment. This state is shown in FIG. 1 b, the air flow being symbolized by the arrows running in the fragrance dispenser.

An illustration of the opened silicone valve can be found in the corresponding detail view of FIG. 1 b. The silicone valve 6 remains only in its open position, as long as the pressure within the fragrance dispensing device 1 is large enough and an air flow through the opened silicone valve 6 is passed. If the internal pressure of the fragrance dispensing device 1 falls below a predefined value, the silicone valve 6 closes and prevents further release of perfume.

Another embodiment of the known from Fig. 1a-b odor dispenser is shown in Fig. 1 c-d.

In this case, the carrier material 4 is a liquid which is received in a container closed with a permeable membrane. The membrane is designed such that fragrance or other active substances pass through the membrane, but not the carrier material.

The container may be fixed to one of the walls 2 or 3. As already described at the outset, a squeezing of the container walls 2, 3 generates a pressure and an air flow through which fragrance-laden air is released from the fragrance dispensing device into the environment. The container opening 5 can be closed by a removable closure cap 7. This is shown in Fig. 2a-c. The closure cap 7 can - as shown in FIGS. 2a-b - be completely detachable from the perfume dispensing device 1 or, as can be seen from FIG. 2c, be integrally formed on the perfume dispensing device 1 via a hinge.

FIG. 3 shows a combination of the fragrance dispensing device 1 known from FIGS. 1-2 with an L-shaped cardboard 10. The fragrance dispensing device 1 is connected to the cardboard 10 via the fastening means 8. The carton 10 is for example freely movable or fixedly placed on a shelf 9.

The fragrance dispensing device 1, the fastening means 8 and the carton 10 as a presentation element together form a fragrance presentation system, wherein the fragrance delivery device is associated with a product and the fragrance released by the fragrance delivery device 1 substantially corresponds to the fragrance releasable by the product.

It is also possible to arrange a plurality of such fragrance presentation systems 1, 8, 10 in a rack 9 next to one another, which is shown by way of example in FIG. 4. The carton 8 may have graphic or textual information elements 11.

The application of the scent delivery device 1 is shown in FIG. By squeezing the fragrance dispensing device 1, a fragrance-laden flow is generated, which forms a flow cone at the outlet from the container opening 5, which is indicated in Fig. 5 by the dashed line. The flow cone is directed to the nose of the user, so that the fragrances can be specifically absorbed. The conical flow ensures that the fragrances are released as locally and spatially as possible.

The flow cone 12 preferably has an opening angle α between 0 ° and 10 °. 5, the opening angle α of the flow cone 12 is formed between the axis 14 perpendicular to the opening plane of the container and a leg of the flow cone 12th

Figure 6 shows a spring-mounted silicone valve 6, wherein the silicone valve in the partial illustration (A) in the idle state, in the partial illustration (B) in the end position and in the partial illustration (C) is shown with an open slit 14. The spring-mounted silicone valve 6 comprises a valve cylinder 15 on which a peripheral valve lip 16 is fixed and on which in turn the valve plate 17, which has a smaller diameter than the valve cylinder 15 is arranged. The valve lip 16 is formed in such a way that the valve disk 17 can move up and down in the valve cylinder 15, which is indicated by the arrows in FIG.

If the user now presses on the container, so that an internal pressure is created, the valve plate 17 initially rises from its rest position (partial image (A)) into the end position (partial image (B)). The silicone valve 6 is thus arranged so resiliently in or on the container opening that it moves until reaching a defined internal pressure in the container X from a first rest position to a second end position.

If the internal pressure in the container exceeds a defined size, the silicone valve 6 opens by the triangular segments of the slit 14 of the silicone valve 6 being folded outwards and air laden with volatile substance being released to the environment. (Partial illustration (C))
