To release the active substances from the chamber into the environment, the chamber has at least an opening on. The opening is preferably designed such that the carrier material can not pass through the opening.

Polymeric carrier material

For perfume-containing Particles are generally all polymers or polymer mixtures, which the necessary criteria with respect to the melting or softening temperature fulfill. In the context of the present application preferred scent delivery systems are 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 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, Polyether esters, polyisobutene, polyisoprene, ethylene / ethyl acrylate copolymers, Polyamides, polycarbonate, polyester, polyacrylonitrile, polymethylmethacrylate, Polyurethanes, polyvinyl alcohols contains.

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 ultra-high molecular weight (about 200 000-5 000 000 g / mol or 3 000 000-6 000 000 g / mol) under the short name ND-HMW-PE or UHMW-HD-PE. Also products with medium Density (MDPE) of blends of polyethylenes lower and higher 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 water vapor permeability, the diffusion of Gases as well as of flavorings and ethereal substances by polyethylenes is relatively high. The mechanical properties are highly dependent on Molecular size and structure the polyethylene. In general, the degree of crystallinity and the density of polyethylenes are increasing 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 from shock resistance, transparency, swellability and solubility. At the same density, the molecular weight of the polyethylenes increases Tear resistance, Elongation, shock resistance, impact resistance and creep resistance to. Depending on how you work in the polymerization you can products with paraffin wax-like Properties (MR around 2000) and products with highest toughness (MR over 1 million) receive.

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 -

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 to either highly crystalline isotactic or less crystalline syndiotactic or 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 a certain embrittlement the polypropylene, but by copolymerization of propylene with ethylene (EPM, EPDM) to much lower temperature ranges can be moved. In general, 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 sensitive to light, which is why the addition of stabilizers (antioxidants, Light stabilizer, UV absorber) 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 divided into two groups divide the aminocarboxylic acid types (AS) and the diamine-dicarboxylic acid types (AA-SS, where A denotes amino groups and S carboxy groups). The former are made up of only a single monomer z. B. Polycondensation of 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 polyaramides 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 temperatures 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 three or polyhydric alcohols with polyfunctional carboxylic acids. The polyesters are generally also the polycarbonates (polyester carbonic acid) expected. AB type polyesters (I) are u. a. Polyglycolic acids, polylactic acids, polyhydroxybutyric acid [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 varies widely in their properties and 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 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 by Urethane Groups - NH-CO-O- connected are. Polyurethanes are generally made by polyaddition two or more Alcohols and isocyanates obtained.

ever optional 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 bearing 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 produced in the polyaddition, when water and / or carboxylic acids are present, because these react with the isocyanates with elimination of impulsive and foaming carbon dioxide. With polyalkylene glycol ethers as diols and water as the reaction component to get to flexible polyurethane foams, with Polyols and propellants from CFCs (especially R 11) are obtained rigid polyurethane foams and structural or integral foams. Additional auxiliaries needed are here z. As catalysts, emulsifiers, foam stabilizers (especially polysiloxane-polyether copolymers), Pigments, aging and flame retardants. To the manufacturer of too complicated shaped objects made of polyurethane foam In the 1970s, the so-called RIM technology was developed (Reaction injection molding). The RIM-Verf. based on 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, soles, Window profiles and TV housings generated.

The general description of the applicable perfumes (see above) provides in general the different substance classes of fragrances To be perceptible, one must Perfume be volatile, besides the nature of the functional groups and the structure the molecular weight of the chemical compound also plays an important role plays. So most perfumes have molecular weights up to about 200 Dalton, while Molar masses of 300 daltons and above rather an exception. Due to the different volatility changed by fragrances the smell of a compound of several fragrances perfumes or perfume during vaporizing, whereby the odor impressions in "top note", "middle note" body) and "base note" (end note or dry divided out). Because the smell perception to a large extent also on the smell intensity is based, the top note of a perfume or fragrance is not alone from volatile Connections while the base note for the most part from less volatile, i.e. adherent fragrances. When composing perfumes can be easier volatile For example, fragrances can be bound to specific fixatives. which prevents it from evaporating too quickly. At the following Classification of the fragrances in "lighter volatile or "adherent" fragrances So over the smell impression and about it, whether the corresponding perfume perceived as a head or middle note nothing is 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.

1 shows the trigger spray dispenser according to the invention 1 in a schematic perspective view. The trigger spray donor 1 has a housing 2 out, which encloses a volume, which essentially by the lateral surface 3 and the housing head 4 is defined. On the housing head 4 opposite side of the housing 2 is a lock 5 arranged by which the trigger spray dispenser 1 can be fixed on a bottle.

Inside the case 2 is the pump 6 arranged. The pump 6 is over the coupling element 13 with an operating lever 8th coupled. An actuation of the lever 8th by the user in this case causes a pumping stroke of the pump 6 , A riser 9 is on the sump side communicating with the pump 6 connected and protrudes with its distal end over the edge of the closure 5 out into the preparation in the bottle.

The pressure side is the pump 6 with a spray head 7 connected through which the subsidized preparation is discharged as a spray, jet or foam to the environment.

Inside the case 6 are in the spaces between the pump 6 and the housing 2 are formed, air freshening substances 10 arranged.

The interior of the housing 2 is designed so tight against the environment that the air freshening substances 10 not inadvertently out of the housing 2 can escape.

As in 1 shown is the housing interior 11 with a solid 10 filled. The solid 10 can For example, be a carrier material for air freshening substances such as a fragrance, or filter out as undesirable adsorbent odors from the ambient air. The adsorbents may be, for example, activated carbon and / or zeolites.

At the head 12 of the housing 2 are openings 12 arranged a passage between the interior 11 of the housing 2 and the environment of the trigger spray donor.

Through these openings 12 can be ambient air in the interior 11 of the housing 2 inflow and in contact with the air freshening substances arranged there 10 occur with the thus laden or purified air through the openings 12 can flow out into the area again.

The openings 12 are designed such that the air freshening substances 10 not inadvertently out of the housing 2 can escape.

So can the openings 12 in particulate air freshening substances 10 be made smaller than the average particle size of the air freshening substances, so that the particles are retained sieve-like in the housing while air in the chamber 11 of the housing 2 can flow in and out.

Is the chamber 11 of the housing 2 not filled with a solid, but filled with a liquid or gel, the openings can 12 be sealed by a permeable membrane that seals the gel or liquid inside the chamber 11 withhold, but air freshening substances, especially perfumes, happen.

The pump 6 may be configured such that during a pumping stroke, a portion of the resulting overpressure through a valve into the air freshening substance 10 filled chamber 11 is directed. As a result, an air flow in the chamber 11 generated by those in the chamber 11 perfume-enriched air through the openings 12 is delivered to the environment.

This makes it possible, a defined fragrance-laden air volume on actuation of the trigger from the chamber 11 into the environment of the trigger spray dispenser 1 to dose.

2 shows a further embodiment of the invention Triggersprühspenders 1 in which the chamber 11 on the outward side of the housing head 4 is trained.

In the chamber 11 is a blister pack 14 insertable. The blister pack 14 has at least one cavity for receiving air freshening substance 10 on. At least one surface of the cavity is at least partially provided with a permeable membrane which is permeable to active substances such as fragrances and, for example, carriers such as gels or liquids.

The blister pack 14 can through a corresponding opening in the mantle or top surface of the chamber 11 laterally into the chamber 11 inserted or from the top into the chamber 11 be used.

Indicates the chamber 11 , as in 2 shown having an opening in the head surface, this opening may be through a chamber closure 15 be closed, with the closure 15 openings 12 to deliver the effective air freshening substances 10 having.

As in 3 shown, the blister pack 14 in the chamber 11 be arranged in such a displaceable that in a first position with the air freshening substance 10 filled cavities from the closure 15 be covered, so that no or only small amounts of air freshening substance 10 while in a second position the air freshening substance 10 filled cavities through the openings 12 of the lock 15 are released so that the air freshening substances are released to the environment.
