Description

Report of the Invention Patent for "INSECT FIGHTING DEVICE UNDERSTANDING AN INCANDABLE PAPER SUPPORT, USAGE AND PREPARATION PROCESS".

[001] The present invention relates to a paper impregnated with insecticidal active substances, process for its preparation and its use for insect control.

It is known that it is possible to kill or repel insects, for example mosquitoes, with the aid of electric heaters, for example, the so-called tablet vaporizers. In this process, suitable substances such as cellulose and cotton board, asbestos, ceramics and / or porous synthetic resins are impregnated with solutions of insecticidal active substances, whereby insecticidal tablets are obtained. Insecticides are volatilized by the action of a heater that produces a temperature of 120 to 190 ° C.

Substantial disadvantage of these tablet vaporizers is that these vaporizers, during the predicted time to act, do not disperse the active substances evenly. Most active substance release is unnecessarily high at the beginning of operation and then decreases continuously and strongly. The effectiveness of these vaporizing tablets weakens over the intended period of use.

Domestic vaporizers have also been known for some time, as for example described in GB-B-2 153 227; Here a vaporization of a liquid occurs, whereby the active substance is dissolved, for example, in a mixture of saturated aliphatic hydrocarbons by means of an electrically heated wick.

The huge amounts of organic solvents required for these so-called liquid vaporizers, relative to the active substance, lead to an undesired high concentration of solvents in the enclosure, which leads, among others - to constantly complain. users - dirtying walls and objects that are near these devices.

[006] In order to repel the pest of annoying insects, battery-operated vaporizers are known in which the surface of a radiation plate for spraying an insecticide is heated to a temperature between 90 and 130 ° C (DE 195 25 782 TO 1).

In addition, from DE 20 2004 008 226 IU, insect-fighting fuel bodies, particularly crickets, are known to have a supporting structure provided with pores and / or hollow spaces and a wax oxidizer and / or paraffin and / or stearin, the oxidizer containing a fraction of cytrone oil.

In addition, spraying of insecticides with the aid of electrically driven fans is known, which blow an air flow over a support impregnated with a solution of insecticidal active substances. Fan systems of this type are described, for example, in WO-A-96/32843.

From EP-B-0 279 325 there are known natural and synthetic transfluthrin-impregnated substances, for example also anti-scratch papers.

From DE 199 47 146 A1 support materials are known which are impregnated with 0.05 mg / cm2 active substance of the transfluthrin series, strong pinamine, vaportrin, pralethrin. Supporting materials are used at room temperature to combat flying insects indoors. Because of the volatility of insecticidal active substances, they are released from the carrier material and thus provide a certain concentration of insecticidal active substance in the air. The systems described in DE 199 47 146 A1, however, are disadvantageous, since on the one hand in case of longer storage already release the insecticidal active substances not making clear to the user what effect such a system already stored actually produces. in later use. On the other hand, the release of the insecticidal active substance from the system is not effective enough.

In addition, fumigation coils are known, such as Baygon® Coils which protect for a period of 6 to 12 hours against mosquitoes, for example on terraces, balconies, in campsites or in the bedroom. For the use of the rings, they are lit with which the ring is red-hot so that the active substance contained therein is slowly and continuously released outdoors or in the enclosure. For an enclosure of approximately 20 m2 a commercially obtainable ring is required. However, the disadvantage of these rings is that during use they tend to break easily so that only part of them can be worn.

In addition, insect-fighting aerosols or oil-based aerosols are used in order to quickly rid insects indoors. Enclosures treated in this manner may then be re-ventilated provided that new insects cannot be entered. Corresponding systems, however, have the disadvantage that aerosol mist or oil aerosol mist, by virtue of their mass, is not sufficiently distributed in environments.

It is common to all these products that they are technically and logistically complicated, slow and therefore expensive to produce. Furthermore, the preparation of quantitatively larger aerosol, oil-based aerosol and spiral products requires the consumption of a huge amount of natural resources such as kerosene, propane / butane, sawdust, adhesives, starches as well as various formulation aids. Their use also requires the subsequent disposal of the corresponding packaging, such as cans, valves, plastic bottles, outer packaging, etc.

Thus, in view of the state of the art described above, it is the task of the technician to provide an insect fighting device that avoids as much as possible the disadvantages mentioned above.

[0015] The solution to this task begins with a first embodiment of an insect fighting device, which comprises an incandescent holder.

Support is characterized in that it is provided with at least one insecticidal active substance.

Thus, according to the invention, in a first embodiment there is provided the preparation of an insect fighting device which is provided with an incandescent support provided with at least one insecticidal active substance, for example by impregnation. . The holder is configured according to the invention in such a way that - once lit - after extinguished, for example by blowing or gusting wind, it remains red-hot and does not go out completely. By burning, the support releases at least the active substance insecticide, with which occurs the fight against insects.

Support Within the scope of the present invention the support is not subject to any restriction provided that, while burning, it is able to release at least the active insecticidal substance.

Suitable as a support is, for example, a cellulose-based support. In this connection, for example, a paper support is mentioned, which is described below in more detail within the scope of a preferred embodiment. Other cellulose-based materials are, for example, wood chips, wood chips or sawdust, rice husks, corn cobs (preferably without grains), pecan shells and peanut shells. Particularly also thin wood chipboard may be used as a support material. A corresponding cellulose-based support is described, for example, in German patent application DE 43 223 76 A1, the contents of which are included in the present application by reference.

Another possible support is based on textile materials. Such a support may contain partially or wholly synthetic fibers such as polyester or nylon or natural fibers such as cotton, mistletoe, a linen-viscose blend or a mixture of synthetic and natural fibers such as cellulose-polyester (synthetic paper) or cotton-polyester. Other examples are feltine wool ("Woll-Feltine") and Trevira-setim.

Another possible support is based on burnable synthetic materials such as polycarbonates, polyesters, polyamides and polyterephthalates. Thus, it has been found within the scope of the present invention that the support element for the insecticidal active substance may be made of synthetic material into which, prior to the definitive preparation and formation process for the support element, the active substance. This is characterized within the scope of the present invention by the fact that its activity is not adversely affected or is only slightly adversely affected by the support element formation process, however, however, the burning of the synthetic material support may be released from this with an essentially constant evaporation rate. Particularly suitable for the preparation of the substrate is the injection molding process whereby to the starting material of the synthetic material, for example a polycarbonate, the insecticide active substance, for example a pyrethrum, may be added by mixing and this The mixture is then processed into an injection molding form in the definitive form shown. Alternatively they are offered as finishing processes, for example also extrusion or deep drawing.

Within the scope of the present invention, the use of a cellulose-based support is particularly preferred.

Furthermore, within the scope of the present invention the use of a paper support is most particularly preferred.

[0024] The solution of the task of the present invention comes from a very particularly preferred embodiment of an insect fighting device comprising a non-slip paper support.

The paper support is therefore characterized by the fact that it is provided with at least one insecticidal active substance.

According to the invention, in this very particularly preferred embodiment there is provided the preparation of an insect fighting device which comprises an incandescent paper carrier provided with at least one insecticidal active substance, for example. by impregnation. The paper holder according to the invention is configured such that - once ignited - once extinguished, for example by blowing or gusting wind, it remains red-hot and does not completely erase. By burning, the paper backing releases at least one insecticidal active substance, thereby causing insect fighting.

In a particular embodiment of this very particularly preferred embodiment of the present invention, the device according to the invention consists of the carrier, particularly the paper carrier, of at least one insecticidal active substance and optionally other additives such as for example potassium nitrate. Other additives are described below.

Cellulose-based support - paper support The device according to the invention according to the first embodiment comprises a paper support. The paper support contains cellulose. Under cellulose, within the scope of the present invention is meant the mass which results from the chemical digestion of plant fibers (in most cases wood) and which consists predominantly of cellulose.

Paper carriers of the type according to the invention have long been known, but not in the field of insect control. About 150 years ago a paper backing was impregnated with the Asian vegetable resin "Stirax", and the resulting product was called "Armenian paper". This "Armenian paper" is used to counteract the smell of food and tobacco and other unpleasant smells. The Frenchman Auguste Poncet brought, from one of his trips to Armenia, the resin that is also used for the production of incense and so remembers its smell. Paper is sold in blocks with different amounts of sheets. For use of this paper a sheet is removed from the block, lit in an ashtray and then erased so that it burns slowly without fire. During burning, the paper releases the desired aromas and provides a pleasant aroma around it. The paper substrate according to the invention is similarly used.

Basically there is no particular limitation on the use of the paper support employed provided that it is generally appropriate to absorb at least one insecticidal active substance and, upon being lit and then erased, to release at least one insecticidal active substance. without substantially decomposing.

However, it has been found that paper carriers having a preferred paper weight of 25 to 300 g / m2, particularly 25 to 270 g / m2, particularly preferred 25 to 250 g / m2, very particularly preferred 25 to 230 g / m2, and even more particularly preferred 25 to 215 g / m2, particularly 25 to 200 g / m2, are especially suitable for the purpose of the invention.

Further, it is preferred when the thickness of the paper support is in the range of 0.1 to 0.5 mm, particularly preferred 0.15 to 0.45 mm, most particularly preferred 0.15 to 0, 40, and even more particularly preferred between 0.15 and 0.34 mm, especially 0.15 to 0.32 mm.

There are no restrictions regarding the individual size of the paper supports of the present invention. However, the paper support according to the invention should be present cut so that it can be properly used by the user, that is, for example to a size that makes it possible to let the paper support burn within a container, for example an ashtray.

The paper support, for example to be employed according to the invention may be, for example, a cardboard support, for example absorbent cardboard, paperboard or corrugated cardboard. Insecticide active substance In the device according to the invention a support may be used, particularly a paper support which is provided with only one insecticide active substance. Alternatively it is also possible for two or more insecticidal active substances to be provided simultaneously on the support, particularly on the paper support, such as 2, 3 or 4 insecticidal active substances.

The choice of the appropriate insecticidal active substance is subject to only one limitation, namely that the insecticidal active substance under the burning temperature of the carrier, particularly the paper carrier, of approximately 350 to 600 ° C is released. essentially without decomposition in the surrounding atmosphere, essentially without losing its insecticidal effect. By "essentially no decomposition" is meant, within the scope of the present invention, when the decomposition is at most 80%, preferably at most 70%, particularly preferred at most 60%, most particularly at most 50%, especially at most 40%. In a first embodiment of the present invention the paper substrate is impregnated with at least one insecticidal active substance chosen from the group consisting of acrinatrine, alethrin, d-alethrin, d-trans-alethrin, d-cis-trans-alethrin, alfamethrin, batrin, bifenthrin, bioaletrin, S-bioalethrin, bioalerine-S-cyclopentyl isomer, bioethanomethane, biopermethrin, bioresmethrin, clocitrin, clovaportrin, cycloprotrin, cyfluthrin, beta-cyfluthrin, cyhalothrin, gamotropin cypermethrin, alpha-cypermethrin, beta-cypermethrin, cis-cypermethrin, theta-cypermethrin, zeta-cypermethrin, cyphenothrin, deltame-trine, depalethrin, empenthrin, empenthrin (1R isomer), esbiotrin, sphenvalerate, fenfenitrin, phenofrin, phenophenitrine fenva-lerate, flubrocitrinate, flucitrinate, flumethrin, fubfenprox, imiprotrin, cadetrin, metofluthrin, neopinamine, permethrin, cis-permethrin, trans-permethrin, phenothrin, pfenotrin (1R-trans isomer), d-hay trine, prale-trine, profluthrin, protrifenbuto, strong pinamine, pyresmethrin, pyrethrin, resmethrin, cis-resmetrin, RU 15525, silafluofen, tau-fluvalinate, te-flutrin, tetramethrin (phthaltrin), tetramethrin (isomer 1R, tertrethrin) , transfluthrin, ZXI 8901, pyrethrin (pyretrum) and any other mixture of the above-mentioned active substances.

By using a matrix material in which the insecticide active substance is incorporated, it is achieved that the insecticidal active substance essentially does not escape after preparation and prior to use of the product according to the invention and that the product according to the invention do not modify its structure.

Suitable matrix materials are all systems which prevent at least the insecticidal active substance from escaping from the support material, particularly from the paper support, under normal ambient conditions (23 ° C, 1013 mbar).

Organic substances which are suitable as matrix materials include polyvinyl alcohol, wheat protein and its derivatives, carbohydrates, starches (from different plant sources), amylose and its derivatives, amylopectin and its derivatives, cellulose and its derivatives, hydrolyzed starches, modified starches, maltodextrin, hydroxypropyl methylcellulose (HPMC), polyvinylpyrrolidone (PVP), chitin, chitosan, polysaccharide gums and their derivatives, polyethylene glycol, polyester, hydroxyalkyl starches, polyvinyl cellulose pyrrolidone derivatives , gelatines, solubilized proteins, polyacrylamides, polyamines, styrene maleic acid resins, polyethylene amine, xanthan gum.

Other examples may include polyacrylates such as cross-linked or epoxidized maleinized polymers and cross-linked (meth) acrylate polymers. Preferred are condensation products of a maleinized or epoxidized polymer and a crosslinker, preferably a polyamine. Suitable polymers are, for example, polydienic reaction products such as polybutadiene, polydecadiene and soybean oil with a molecular weight of over 400 g / mol with maleic acid anhydride, as well as olefin copolymers such as ethylene with maleic acid anhydride as well as epoxidized polybutadiene. Preferred crosslinkers are polyamine, particularly polyoxypropylenediamine and poloxypropylenetriamine. In addition they are also suitable as a triethylene glycol, polyethylene amine and urea crosslinker. The cross-linking reaction is preferably carried out in alcoholic solution, for example in dipropylene glycol under elevated temperature. Maleic acid anhydride groups or epoxy groups or the -NR-CO- groups of the crosslinked polymer and -CRH-O- groups derived from polyoxyalkylene polyamine have hydrophilic action.

Another class of crosslinked polymers are copolymers of monofunctional (meth) acrylate monomers, for example ethylene glycol dimethacrylate or polyethylene glycol-400-dimethacrylate. The cross-linked (meth) -acrylate polymers are prepared by radical copolymerization of the monomers. In both cases, cross-linked polymers are capable of absorbing liquids and gases, for example finely divided insecticidal active substances in liquid, dissolved or dispersed form.

Also suitable as matrix formers are solid alkanecarboxylic acids and metal salts of alkanecarboxylic acids in gel form. Preferably, stearic acid and alkali metal salts of stearic acid, such as sodium stearate and, in addition, mixtures of stearic acid and palmitic acid or alkali metal salts thereof, for example mixtures of sodium stearate and palmitate, are mentioned. sodium. Corresponding matrix formers are described in DE 196 24 819 A1, the relevant disclosure of which is incorporated herein by reference.

As other examples, inorganic substances may be mentioned, for example silicic acid, polysilicates, polyphosphoric acid and its derivatives, polyboric acids, clay, etc.

In addition, micro-encapsulated insecticidal active substances may be used. By micro-encapsulating the individual insecticidal active substances, unwanted release under normal environmental conditions can be prevented. Corresponding systems are described in DE 100 22 989 A1, the relevant disclosure of which is incorporated herein by reference.

Preparation Impregnated support materials to be employed according to the invention, in particular paper support materials, provided that the support, particularly the paper support is not impaired by impregnation, may be prepared by all methods of usual impregnation, for example by spraying the support with a solution of the insecticide and subsequent drying, for example, by air, or by immersing the support in an insecticide solution and subsequent drying, for example, by air. Other suitable impregnation methods are impregnation with the aid of a pipette, ink jet process ("nk-jet-proces $") as well as a screen printing process.

The carriers, particularly paper carriers, of the insecticidal substances of the present invention may therefore be prepared, for example, in one embodiment by impregnating appropriate carrier material, particularly paper, with a corresponding solution or emulsion. . Preferably as starting material herein are carriers, particularly paper carriers of the above specification, which have already been provided with the corresponding amounts of potassium nitrate. In another embodiment of the present invention the carrier, particularly the paper carrier, is provided with a glowing syner-gisf. This may be, for example, potassium nitrate or potassium permanganate.
