Description

The The present invention relates to a scent delivery system for deodorization and / or for scenting rooms according to the preamble of claim 1. Such scent delivery systems be on rotatably mounted paper rolls, especially on toilet paper rolls or applied to household paper rolls and include one with a plurality of openings provided container, which encloses a receiving space, which is partially filled with a plurality of Duftträgerpartikeln. The openings are dimensioned so that they are on the one hand an issue the fragrances of the fragrance carrier particles from the recording room to the outside enable, but on the other hand, the small fragrance carrier particles are not through the openings can escape through from the recording room.

In lavatories especially in the absence of fresh air often unpleasant Smells on. To keep the toilet air fresh and eliminate the annoying odors or possibly To reduce largely are in addition to fragrance sprays various Room freshener known.

These room fresheners may be, for example, a solid impregnated with perfume or other fragrant formulation, which usually has a specific shape or optical design for decorative purposes. Such Raumuftufter, which is used directly on a toilet paper roll, is from the US 5 170 938 known. It comprises two attachable to the two end faces of a toilet roll paper discs, from which for decoration purposes each different patterns, symbols or figures are punched out. These discs, which are also individually usable, can either be impregnated directly with a perfume formulation or they can serve as a support for a separate fragrance carrier, which in turn is impregnated with a perfume formulation. However, such a room freshener has a decreasing fragrance intensity over its duration of action and thus a decreasing scenting of the ambient air. This is a common problem of common passive fragrance dispensers, which alone allow a diffusion-related subsequent delivery of the fragrance from the fragrance-bearing material.

Other Room fresheners include one with openings provided housing, that with different air purifying and / or fragrance releasing Filled substances can be.

So beats WO 2004/020004 before a scent delivery system, which in a rotationally symmetrical container with Crescent-shaped cross-sectional shape a variety of perfume-bearing Contains particles. The system can, for example, over an attached holding device at a suitable location in hung up a toilet and give off fragrance there.

From the US 2,753,209 a retaining roll for a toilet paper roll is known, which forms a housing for an inset cylindrical Duftträgerstift. The retaining core consists of two fingers axially interlocking core halves, which are pressed apart by means of a coil spring to engage each with an externally axially projecting hub in a receiving bore of a holder for toilet paper rolls.

Between the two core halves are several axial openings provided by the fragrances of the scent carrier pin from the retaining core can escape.

From Disadvantage of this embodiment is the relatively complex construction, which makes the room freshener not only expensive to manufacture, but due to friction between the moving core halves too wear subject and therefore vulnerable is for malfunctions. Besides, too This room freshener as a passive fragrance dispenser over its time of action a continuous decreasing scent intensity and thus a decreasing scenting of the ambient air.

It would be, however desirable, if in each case a short-term increase in the fragrance delivery achieved could be if the ambient air is particularly heavily loaded with unpleasant odors is.

This suggests the US 6,688,551 a scent delivery system wherein the toilet roll support core has an internal reservoir for a high intensity perfume formulation that is delivered to one or more exit ports via an internal transport system. This retaining core also comprises two core halves with frontal hubs, which are pressed apart axially by a spring, so that the retaining core can be fixed almost rotationally fixed in a holder for toilet paper rolls. When unrolling toilet paper is Due to air turbulence, an increased amount of the perfume formulation delivered, so there is a short-term increased fragrance delivery.

Also this fragrance delivery system has due to the spring mechanism and the internal transport system is a relatively complicated construction on, resulting in higher Production costs adversely affected. In addition, the intended short-term falls increase not always in the desired Dimensions off.

Another fragrance delivery system with an increased if necessary fragrance delivery is from the US 4,497,456 known. This scent delivery system of the aforementioned type also comprises a holding roll for a toilet paper roll, which forms a container provided with a plurality of openings for receiving a plurality of small Duftträgerpartikeln. This retaining core is freely rotatably mounted in the toilet paper holder, so that the rolling of toilet paper due to frictional phenomena also causes rotational movements of the retaining core. During the rotation of the holding core, the fragrance carrier particles fall through each other, which leads to new arrangements of the individual fragrance carrier particles relative to each other. As a result, new surface areas of the fragrance carrier particles are always exposed, resulting in a so-called booster effect in the desired short-term enhanced fragrance delivery.

There However, the retaining core is free, so regardless of the toilet paper roll can turn is a reliable Effect of the booster effect not always guaranteed. Especially when paper is peeled off at a higher speed will, could the desired Rotary movement of the retaining core fail only to a much lesser extent or even completely remain under.

Another, similarly constructed system is from the US 4,759,510 known. This patent describes a retaining roll for toilet rolls, which is designed as a container for fragrance carrier particles which, when the core rotates, break up and give off fragrance.

One general problem with such Raumgeduftern in the form of holding cores is also that they only in such holders of paper rolls can be used in which the original retaining core completely removable is. However, modern brackets often have a one-sided fastened, in particular in one piece executed with the bracket and preferably relatively thin trained holding axis on which a roll of paper pushed axially becomes. In such modern brackets are the aforementioned Fragrance dispensing systems with exchangeable retaining core therefore not applicable.

One Another disadvantage of the fragrance delivery systems with replaceable holding core is that the fragrance only within the core tube of Paper roll emerge and therefore the ambient air only by detours and in limited Reach dimensions can. The deodorization or fragrance of the burdened with unpleasant odors Therefore, space can not achieve optimal effectiveness.

task The present invention is therefore a structurally simple, inexpensive to produce and easy to handle fragrance delivery system to create the type mentioned, even with paper rolls can be used with non-replaceable holding core and that at a always effective and highly effective room scenting reliable one briefly increased Scent delivery when unrolling paper allows.

These Task is achieved by a scent delivery system according to claim 1. Advantageous embodiments and further developments of the invention will become apparent from the dependent claims.

Essential in the inventive solution it, that the container annular is formed and an annular Enclosing space encloses and that the container force fit and / or positively acting Fastening means for non-rotatable connection of the container with a paper roll and / or having the core tube of a paper roll.

Of the The main advantage is that a ring-shaped container together with a paper roll also on fixed holding axes of paper roll holders is deferrable. Thus, one according to the present invention annular trained container For example, together with a toilet paper roll on a fixed support axis of a toilet roll holder be deferred. Nevertheless, the container can also be removable Both sides mounted holding cores older design can be used. Therefore, the fragrance delivery system of the invention especially with all known types of toilet paper roll holders be used.

there it does not matter to the cross section of the annular receiving space. So For example, the cross section can be oval, but also with straight lines and / or corners may be formed. In particular, the recording room executed in the form of a torus be. It is only essential that the container in the form of a ring with a for conventional Axles and core roles sufficiently large dimensioned free interior accomplished is so that he can rotate freely on an axle without jamming phenomena or core role of a paper roll holder can be plugged.

One Another significant advantage is that due to the rotational, Attachment of the annular container independent on the paper roll from the unwinding always a sufficient rotational movement of the container and thus reliable the desired increase the scenting is achieved when unrolling paper.

On This structurally particularly simple way is also a Scent delivery system created in which the openings of the container free accessible and thus the fragrances of the Duftträgerpartikeln directly without detours can be discharged to the ambient air, resulting in an optimal effective deodorization or to a highly effective scenting of with unpleasant odors burdened room leads.

The Fragrance delivery system according to the invention is inexpensive to manufacture and easy with a simple design to assemble or easy to handle. For attachment to a roll of paper can the fastening means preferably be designed so that a simple axial attachment of the annular container on a front side of a Paper roll the intended non-rotatable connection with the paper roll or with the usual made of cardboard core tube of a toilet paper roll or a Paper towel generated. additionally This can also be a non-positive and / or positive fit be ensured in the axial direction.

For a special light and preferably concentric positioning of the annular container a paper roll strikes the present invention further that the container a Coaxially projecting sleeve having axially from one end face of a paper roll in the Paper roll or in the core tube of a paper roll can be inserted. The sleeve can either attached as a separate component to the container or integral with the container or part of the container be educated.

Especially It is also advantageous if the sleeve is cone-shaped, so that their free end with a smaller outer diameter especially light can be inserted into the core tube of a paper roll.

simultaneously can in this way a non-positive grip on paper rolls can be achieved with different core tube inside diameters.

The Adaptability to different inside diameters of paper rolls can be further improved if the sleeve at least two or more has substantially axial separation slots, starting from from the free end of the sleeve over at least a part of its axial length extend so that the free end portion of the sleeve in two or more peripheral portions is divided, which bend relatively elastically inward to let.

A Particularly preferred type of fastening means provides that on the sleeve at least one elastically outwardly resilient retaining element is provided. Preferably, the holding elements extend as wedge-shaped Retaining webs radially outward, the increasing when plugging into a core tube of a paper roll pressed inwards become a force-fit Lead attachment. Alternative or supplementary can do this the fastening means also include hooks and / or brackets.

Of the container can basically can be made in different ways, he can, for example made in one piece by a blow molding process and then through an opening in the container filled with the particles be, with this opening after filling subsequently is closed.

According to one particularly preferred embodiment The invention consists of the container at least two container parts, wherein a first container part a flat or arched one rear wall and one hereby solvable or unsolvable connected second container part a flat or arched one Front wall includes. When the container is formed in two parts, can the two container parts be produced in a particularly simple manner by injection molding.

A releasable Attachment of the two container parts allows each other while a slight replacement of the fragrance carrier particles, if after Expiration of their time of action sufficient scenting the ambient air no longer exists. Under the back wall is the wall of the container to be understood in the position of use at the front of a Paper roll is applied.

Especially It is advantageous if the front wall having the second container part a radially inner and a radially outer side wall, wherein the side walls preferably over rounded areas are connected to the front wall. Especially can also have the front of a buckle, so that the second container part is formed overall bead-like. It is also advantageous although the back wall having first container part has a web-like edge region, which is for easy attachment on the side walls of the second container part can be used.

If the container a sleeve of the type described above, it is still of Advantage, if the first container part, which comprises the at least substantially planar rear wall, with the sleeve connected is. Preferably, then the inner diameter corresponds the sleeve in her to the back wall adjacent area to the inner diameter of the inner sidewall of the second container part in her to the back wall of the first container part adjacent area, leaving between the sleeve and the inner sidewall of the container a stepless transition given is.

A particularly advantageous and simple connection of the two container parts can be achieved by that they form fit and / or a force fit, preferably by means of a latching connection or snap connection attached to each other. Also, the two container parts over a or multiple threaded connections or by means of hooks and / or staples be attached to each other.

advantageously, can the openings in the front wall and / or in the radially outer side wall of the annular container be introduced.

hereby The fragrances of the fragrance carrier particles are particularly easy and quickly to the ambient air, resulting in a particularly effective Room scenting leads. The front wall is the wall of the container, which is in the use position facing away from the paper roll.

Preferably are the openings in the process as slots, in particular wave-shaped. You can, however in principle have any shapes and in particular round, oval or be executed drop-shaped.

According to one another preferred embodiment the invention are the openings with removable closure means, in particular with a removable applied or peeled glued foil sealed. hereby is an unintended fragrance delivery before the beginning of the intended use prevents the scent delivery system.

Preferably can also perforated stickers are used as closure means, allowing the selective release of individual areas of openings possible is, so that, for example, at the beginning of the effective time of the scent delivery system first only a few radially inward openings are released and only after a certain time and a decrease in effectiveness more openings be exposed to an increased fragrance and thus again to achieve a satisfactory room fragrance.

According to one particularly preferred embodiment The invention provides that an adjustable closure part is provided, through which the openings of the container optionally completely or partially open or completely can be closed. This allows the openings even after the beginning of the use of the scent delivery system again be closed to his casting time by preventing a to prolong further fragrance delivery, if the toilet, for example, for a holiday certain period is not used.

It is particularly advantageous if the closure part comprises an axially rotatable or pivotally mounted on the annular container cap, which is provided with a plurality of openings which can be selectively completely or partially brought into registry with the openings of the container, wherein in at least a closure position, all openings of the container are covered by the closure areas of the cap surrounding the openings of the cap. The openings in the cap can also be arranged so that with increasing rotation of the cap of the total coverage Grad continuously increases or decreases with the openings of the container to make a dosage of fragrance delivery. In a two-part container design, the cap as the third component of the device according to the invention is preferably articulated on the container part containing the front wall, in particular rotatably clipped on.

Farther beats the invention that the container from a transparent, transparent or semitransparent material is formed. In this way, the consumer can determine the degree of filling of the container and the optical nature and movement of the fragrance carrier particles detect. In particular, you can Here also different colors of Duftträgerpartikeln recognized and for the optical Design of the fragrance delivery system and / or for distinguishing purposes be used in different fragrances. Alternatively to this can the container also completely or partially formed of opaque material and galvanized, in particular chromed to a particularly high-quality metallic To create an impression. In particular, the container and the optionally existing sleeve consist of a polymer or a polymer mixture and advantageously be produced by injection molding.

Under Fragrance carrier particles should be understood to be in particulate form substances that are loaded with at least one perfume. Loading means that the at least one perfume on the surface of the particulate matter and / or adsorbed and / or absorbed in its interior. In other words, that means that a fragrance carrier particle a particulate carrier material means that with at least one fragrance is applied.

When support material come in principle all substances that are able to adsorb fragrances and / or absorb, and which are suitable for use in the device according to the invention Let shape take. Among others come as a carrier material polymers, especially organic polymers, but e.g. also porous inorganic materials such as silica gels or zeolites in question. The latter is on it to pay attention that the fragrance carrier particles have sufficient abrasion resistance, so that during their movement in the device no unwanted dusts arise. As a carrier material preferred are polymers, in particular organic polymers.

Especially It is also advantageous if the number of fragrance carrier particles in the container between 10 and 5,000, preferably between 50 and 1000.

Cheap is it also if the fragrance carrier particles an average diameter of 0.5 to 20 mm, preferably from 1 to 10 mm and in particular from 3 to 6 mm.

Farther is proposed, the annular Recording room between 10% and 90%, preferably between 30% and 80%, in particular between 50% and 70% of its volume with fragrance carrier particles to fill.

By the choice of these three parameters (number and size of fragrance carrier particles as well as degree of filling the receiving space) in the aforementioned areas can be an optimal Compromise between a for one possible long-lasting fragrance delivery required large total volume of fragrance carrier particles and one for the wished Booster effect essential mobility of the fragrance carrier particles be achieved.

Fragrance dispensing systems according to the invention contain the carrier materials in the form of particles. As fragrance carrier particles are doing in Within the scope of the present application, particles comprising a solid at room temperature, that is, dimensionally stable, non-flowable consistency exhibit.

The The spatial form of these particles is only due to the technical possibilities limited in their manufacture. As a form of space so come all reasonable manageable configurations into consideration, for example, cubes, cuboids and corresponding Room elements with flat side surfaces and in particular cylindrical Embodiments with circular or oval section. This last embodiment includes tableted Particles up to compact cylinder pieces with a ratio of Height to diameter above 1. Other possible Spatial forms are spheres, hemispheres or "stretched spheres" in the form of ellipsoidal capsules as well like regular ones 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. The surface of the solid particles may have unevenness depending on the type of the selected manufacturing process and / or a selected coating. 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 design forms, the perfume-containing particles are also clearly visually perceptible to the consumer and, through the targeted spatial configuration of these particles, make it possible to visualize the fragrances contained in the agents according to the invention in a way that is particularly advantageous for product acceptance.

The Assembly of the carrier materials to the particles described above can be applied to all those skilled in the art carried out for processing these substances known methods. In the context of the present invention, extrusion, the injection molding and the spraying to granules preferred.

The intended short-term increase Scent delivery when unrolling paper can be particularly effective be designed when in the annular receiving space fixed with the container connected stirring elements are arranged, through which the fragrance carrier particles in a rotary motion of the container intensified mixed become.

in the Preferred scent delivery systems are within the scope of the present application characterized in that the polymeric carrier material at least one Substance from the group comprising ethylene / vinyl acetate copolymers, Low or high density polyethylene (LDPE, HDPE) or blends the same, 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, polymethylmethacrylate, polyurethanes, Contains 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.

When high-pressure method branched low-density polyethylenes fall at (about .915 to .935 g / cm ³⁾ and crystallinity of about 40-50%, obtained as LDPE-type (low density polyethylene), respectively. 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 The polyethylenes from low-pressure process are largely linear and unbranched. These polyethylenes, abbreviated HDPE (from E high density polyethylene) have degrees of crystallinity of 60-80% and a Density of approx. 0.94-0.965 g / cm3. They are considered products with high or ultrahigh molecular weight (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. Also Medium Density Products (MDPE) made from blends of polyethylenes low and high density are commercially available. Linear polyethylenes with densities <0.918 g / cm3 (VLD-PE, from E very low density polyethylene) win only slow market meaning.

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 at. With the density increase shear modulus, hardness, yield strength and melting range; it decreases from 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 mode 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 polyethylene types can be done after all for thermoplastics Methods are done.

Polypropylene (PP) is the name for thermoplastic polymers of propylene with the general formula: - (CH ₂ -CH [CH 3]) _n -

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

polypropylene characterized by high hardness, Resilience, Stiffness and heat resistance. Short-term heating of objects made of polypropylene is even possible up to 140 ° C. At temperatures below 0 ° C occurs one certain embrittlement the polypropylene, but by copolymerization of propylene with ethylene (EPM, EPDM) to much lower temperature ranges can be moved. Generally, the impact resistance can be of polypropylene by modification with elastomers. The chemical resistance is good as with all polyolefins. An improvement of the mechanical Properties of the polypropylenes are achieved by reinforcement with Talc, chalk, wood flour or glass fibers. Polypropylenes are in even stronger Dimensions as PE oxidation and photosensitive, which is why the addition of stabilizers (Antioxidants, light stabilizers, UV absorbers) is required.

polyether is one in the field of Macromolecular Chemistry Designation for Polymers whose organic repeating units are characterized by ether functionalities (C-O-C) held together. According to this definition belongs one Variety of structurally very different polymers to the polyethers, z. 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 polyaryl ether) or polyetheretherketones (see Polyetherketone). Not the polyethers are polymers with pendant ether groups calculated, as u. a. the cellulose ethers, starch ethers and vinyl ether polymers.

to Group of polyethers count furthermore also functionalized polyethers, d. H. Connections with a polyether scaffold, the laterally attached to their main chains still other functional Wear groups such. As carboxy, epoxy, allyl or amino groups etc. Versatile are block copolymers of polyethers and polyamides (so-called polyetheramides or polyether block amides, PEBA).

When Polyamides (PA) are called polymers whose basic building blocks held together by amide bonds (-NH-CO-). Naturally occurring Polyamides are peptides, polypeptides and proteins (Ex .: protein, wool, Silk). The synthetic polyamides are, with a few exceptions thermoplastic, chain-shaped Polymers, some of which are large have achieved technical importance as synthetic fibers and materials. After the chemical structure, the so-called homo-polyamides can be 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 an ω-aminocarboxylic acid (1) (Polyamino) or by ring-opening Polymerization of cyclic amides (lactams) (2) prepared.

Next The homopolyamides also some co-polyamides have gained importance. It is usual in these a qualitative and quantitative statement of the composition z. Eg PA 66/6 (80:20) for from 1,6-hexanediamine, adipic acid and ε-caprolactam in molar ratio 80:80:20 manufactured 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 polya summarized (Ex .: Nomex ^® ).

The most frequently used polyamide types (in particular PA 6 and PA 66) consist of unbranched chains with average molar masses of 15,000 to 50,000 g / mol. You are in solid state semi-crystalline 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 are amorphous. Unlike the generally milky-opaque, semi-crystalline polyamides, these are almost crystal clear. The softening temperature the most common Homo-polyamides are between 200 and 260 ° C (PA 6: 215-220 ° C, PA 66: 255-260 ° C).

polyester is the collective name for Polymers whose basic building blocks are held together by ester bonds (-CO-O-) become. After 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 an ω-hydroxycarboxylic acid 1 or by ring-opening polymerization cyclic ester (lactone) 2 produced.

branched and crosslinked polyesters are used in the polycondensation of tri- or polyvalent ones Alcohols were obtained with polyfunctional carboxylic acids. To the polyesters In general, the polycarbonates (polyester of carbonic acid) are also calculated.

AB-type polyesters (I) are u. a. polyglycolic acids, polylactic acids, polyhydroxybutyric [Poly (3-hydroxybutyric acid), Poly (ε-caprolactone) e and polyhydroxybenzoic acids.

Purely Aliphatic AA-BB type polyesters (II) are aliphatic polycondensates Diols and dicarboxylic acids, the u. a. as products with terminal Hydroxy groups (as polydiols) for the preparation of polyester polyurethanes be used [z. B. polytetramethylene adipate]. In terms of quantity biggest technical Meaning have 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) e (PCDT) as the main representative. These types of polyesters can by Co-use of other aromatic dicarboxylic acids (eg isophthalic acid) or by using diol mixtures in the polycondensation in their Properties widely varied and different application areas be adjusted.

Purely aromatic polyesters are the polyarylates to which u. a. which include poly (4-hydroxybenzoic acid). In addition to the previously mentioned saturated Polyesters can also be unsaturated polyesters from unsaturated dicarboxylic acids produced as polyester resins, especially as unsaturated polyester resins (UP resins), have achieved technical importance.

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

When Polyurethanes (PUR) are polymers in whose macromolecules the Repeating units are linked by urethane groups -NH-CO-O-. Polyurethanes are generally prepared by polyaddition from or higher quality Alcohols and isocyanates obtained. Depending on the choice and stoichiometric relationship The starting materials are thus polyurethanes with very different mechanical properties as components of adhesives and paints (polyurethane resins), as ionomers, as thermoplastic Material for Stock parts, rollers, tires, rollers are used 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 even complicated shaped objects made of polyurethane foam (reaction injection molding) = 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. Among other things, car body parts, shoe soles, window profiles and television casings are produced by means of RIM technology.

enthalten.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

contain.

Commercially available polyvinyl alcohols be as white-yellowish Powders or granules with degrees of polymerization in the range of approx. 100 to 2500 (molecular weights of about 4000 to 100,000 g / mol) offered. The polyvinyl alcohols are characterized by the manufacturers by indicating the degree of polymerization of the starting polymer, the Hydrolysis degree, the saponification number or the solution viscosity.

polyvinyl alcohols are dependent soluble in the degree of hydrolysis in water and a few highly polar organic solvents (Formamide, dimethylformamide, dimethyl sulfoxide); of (chlorinated) Hydrocarbons, esters, fats and oils are not attacked. Polyvinyl alcohols are classified as toxicologically harmless and are at least partially biodegradable biologically. The water solubility can be by post-treatment with aldehydes (acetalization), by Complexation with Ni or Cu salts or by treatment with dichromates, boric acid or reduce borax. The coatings of polyvinyl alcohol are broad impenetrable for Gases such as oxygen, nitrogen, helium, hydrogen, carbon dioxide, however allow water vapor to pass through.

In a particularly preferred embodiment The present invention is the polymeric carrier material the fragrance carrier particle at least partially made of ethylene / vinyl acetate copolymer. Another preferred The subject of the present application is therefore a scent delivery system, characterized in that the polymeric carrier material is at least 10% by weight, preferably at least 30% by weight, more preferably at least Contains 70 wt .-% ethylene / vinyl acetate copolymer, preferably completely of ethylene / vinyl acetate copolymer is made.

Ethylene / vinyl acetate copolymers is the name for Copoylmers of ethylene and vinyl acetate. The production of this polymer takes place in principle in one of the production of low density polyethylene (LDPE; low density polyethylene) comparable methods. 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 resulting products reduced. The vinyl acetate does that Copolymer also polar and thus improves its adhesion 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 the Scent delivery systems are particularly within the scope of the present invention preferred in which used as the polymeric support material ethylene / vinyl acetate copolymer and this copolymer is 5 to 50% by weight of vinyl acetate, preferably 10 to 40% by weight of vinyl acetate and in particular 20 to 30% by weight of vinyl acetate, in each case based on the total weight of the copolymer.

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 the smell perception is based to a large extent on the smell intensity, the head exists note of a perfume or fragrance not only from volatile compounds, while the base note for the most part consists of less volatile, ie 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 that way for inventive agent both the product odor immediately upon opening the brand new agent as well as the use fragrance, for example when used in a Dishwasher, to be influenced. These fragrance impressions can of course be the same could be but also different. For the latter odor impression is the use of more adhesive fragrances advantageous while for product scenting also more volatile fragrances can be used are. Adhesive-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, Edeltannöl, Edeltannenzapfenapfen, Elemiöl, eucalyptus oil, fennel oil, spruce needle oil, galbanum oil, geranium oil, ginger grass oil, guaiac wood oil, Gurjunbalsamöl, Helichrysumöl, Ho oil, Ginger oil, iris oil, cajeput oil, calamus oil, chamomile oil, camphor oil, kanaga oil, cardamom oil, cassia oil, pine oil, copaia balsam, coriander oil, spearmint oil, caraway oil, cumin oil, lavender oil, lemongrass oil, lime oil, tangerine oil, lemon balm oil, musk kernel 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, Verbena Oil, Vetiver Oil, Juniper Berry Oil, Vermouth Oil, Wintergreen oil, Ylang-Ylan g oil, hyssop oil, cinnamon oil, cinnamon leaf oil, lemon oil, lemon oil and cypress oil.
