Description

Pheromone dispenser Description 5 The present invention relates to pheromone-filled pheromone dispensers of two interconnected plastic films, and a process for their preparation. Pheromones have gained increasing importance as insect control gents in agriculture and forestry. A current method of controlling pests in agriculture, in particular in 10 horticulture and viticulture, which employs pheromones is what is known as the confusion method, also referred to as mating disruption technique Or confusion technique. This technique exploits the behavior of some insects ofireleasing pheromones during the mating time in order to attract the respecti e mating partner, which, as a rule, will be the male. If a higher substance concentration of artificially 15 prepared pheromones is introduced into a field, the insects to be a tracted lose their orientation and no longer find their mating partner. Another current method of using pheromones in pest control is mass capture in trap. systems, with the pheromones acting as attractants. A large number of pheromones are known. An overview is found in, for example J. Vitae, Biologie in unserer Zeit 8, 112 (1978) and in 'The Pherobase" 20 (http://www.pherobase.com). The use of pheromones requires suitable active substance dispensers which ensure a prolonged, uniform release of the active substances in order to ac ieve as long-term protection as possible and/or high, uniform trapping results. 25 Known dispenser types are - Film bags made of a pheromone-permeable plastic film material, for example polyethylene film or film laminates made of polyethylene/eth'lene-vinyl acetate copolymers, the film bags comprising, as a rule, a cellulose-l ke, absorptive 30 substance impregnated with the pheromone (see, for example, DE-A 2832248, DE-A 2945655, EP-A 342126); - Dispensers made of plastic material into which the pheromone is incorporated (referred to as barrier-free dispensers, also referred to as mtrix dispensers, see e.g. DE 2356155); 35 - Dispensers in theform of capillary tubes (capillary dispenser ), from which the is dispensed to the environment via an open end of the capillary (see, for example, US 4017030); - Ampoules made of plastic material which are equipped with one or two pheromone-filled chambers, the plastic being selected such that it is permeable 40 for the pheromone (see EP-A 243263, EP-A 236188 and EP{A 413 325). These dispensers are also referred to as hollow-chamber dispensers.

2 The disadvantage of the three first-mentioned dispenser types is that the pheromone is released in a largely uncontrolled manner, depending on the weathdr conditions. The pheromone concentration in the pheromone-saturated material (abs rptive substance 5 or plastic), which is initially high, drops more and more quickly as tin e passes; the point in timewhen the release of the attractant ends cannot be recorded specifically. Frequently, the actual cause for an abating activity -is the exhaustion of the active substance or an insufficient release of the pheromone by the dispenser, caused by whatever. The user is therefore forced to use his experience for determining the point 10 in time at which the conventional dispenser must be replaced before the release of the attractant may have ended. Incorrect use or other factors which are possible (for example as the result of the weather) and which prematurely lead to too low a release of the attractant, or none at all, can be recognized only with difficult . Particularly in forestry applications, dispensers which are still operational are replaced purely as a 15 precaution in order to ensure that the activity is retained. In order to guard against these uncertainties in the release of the active substance, in this ca e at least two, occasionally also three, traditional dispensers are necessarily required during the application, which constitutes an unnecessary cost factor for the usr. 20 The disadvantage of ampoule dispensers is firstly the complicated production by a blow-molding process. The material requirements for the ampoules are relatively high, in comparison with the pheromone quantities. Moreover, the release characteristics are frequently not satisfactory. In particular, the release towards the end, i.e. at a low filling level, is no longer optimal due to the geometry of the dispenser and the variation in the 25 structure and thickness of the material, which is due to the production. The earlier German patent application DE 102008026602.7 describ s a dispenser for highly volatile media with a chamber which is enclosed by a film material and which is intended to receive the medium, which chamber takes the form of al sealed, breakable 30 ampoule, for example a glass ampoule, which comprises the phero mone. The dispenser is activated by breaking the ampoule. There is therefore a need for dispensers which are suitable for the controlled release of pheromones or pheromone bouquets over a prolonged period and Which are simple to 35 produce. The invention is therefore based in particular on the object of providing a dispenser whose release characteristics are at least comparable to or even better than, those of an ampoule dispenser, i.e. which ensures a reliable release of the pheromone, and therefore in fact a reliable activity, even under unfavorable climatic conditions such as changing temperature and light conditions or high temperatures, 40 and likewise over a prolonged period. It has been found that this object can be achieved by the dispensers described 3 hereinbelow. Accordingly, the present invention relates to a pheromone dispens r, filled with pheromone or a pheromone-comprising liquid and comprising (a) q deep-drawn plastic 5 film made of a thermoplastic film material and featuring at least one zone designed such as to form a dish for receiving a pheromone or a pheromone omprising liquid, and (b) a planar plastic film made of a thermoplastic film material dnd which is connected with the deep-drawn plastic film, where the planar plastic film together with the at least one zone designed such as to form a dish of the deep-drawn plastic film 10 forms a durably sealed chamber which comprises the pheromone br the pheromone comprising liquid, and (c) a recess in the zone of the interconnected plastic films, where the planar plastic film is permeable to the pheromone. The dispenser according to the invention entails a series of advantages. In contrast to 15 conventional hollow-chamber dispensers, the dispensers according to the invention feature very precise material structures and thicknesses owing to the use of films, and, thus, ensure constant release conditions independently of the filling level of the dispenser. Moreover, the material requirements are markedly less )han in the case of traditional hollow-chamber dispensers. Moreover, the pheromone, in contrast to the 20 blow-molded or extrusion-molded ampoule dispensers, is usually riot exposed to any elevated temperature during the production since the films are already preformed and only require bonding with each other. They have markedly improv d release characteristics in comparison with film bags, capillary dispensers a Pd barrier-free dispensers. Owing to the film material employed for the production, the dispensers 25 according to the invention are relatively lightweight, small and low, which leads to less transport and packaging effort. The recess provided in the dispenser permits the simple fixing of the dispenser to the branches or shoots of the plants to bd protected. The use of breakable ampoules such as glass ampoules for accommodating the pheromone or pheromone bouquet is still required. In contrast to the dispensers described in German 30 patent application DE 102008026602.7, the dispensers according jo the invention, therefore, typically do not comprise any breakable ampoule components in the chamber(s). Preferred embodiments of the dispensers according to the invention are described in 35 the subclaims and the figures, to which reference is hereby made. The dispensers according to the invention feature at least one dur bly sealed chamber which comprises the pheromone. It is also possible to provide the dispenser with a plurality of durably sealed chambers, it being possible for the chambers to be filled with 4 the same pheromone or different pheromones. In accordance with the invention, the chamber(s) is(are) formed by the zone(s) designed such as to form dish of the deep drawn film and the planar plastic film bonded thereto. Durably bonded means that the deep-drawn film is bonded to the planar film in such a way that they cannot be 5 separated without destroying the dispenser. Bonding the deep-drawn film to the planar film is, as a rule, carried out in such a way that the planar film rests In the zone of the edges or on the borders of the at least one zone designed such as to form a dish of the deep-drawn film and is fixed durably along the edges or borders. D rable fixing is typically effected by means of a welded or sealed seam along the edges of the at least 10 one zone designed such as to form a dish. In order to achieve as uniform release characteristics as possible, tl e'bottom of the at least one zone designed such as to form a dish is largely parallel wfth the planar film. Largely parallel means that at least 70% of the bottom area of the zbne designed such 15 as to form a dish is arranged in parallel with the planar film or forms an angle of less than 100 with the planar film. Furthermore, it has proved advantageous when the depth of the zohe designed such as to form a dish amounts to at least 0.2 mm, in particular to at lealt 0.4 mm and 20 preferably does not exceed 5 mm, in particular 3 mm. In the present context, depth is understood as meaning the distance of the bottom area of the dish nd the plane predetermined by the edge of the dish which are substantially plan4-parallel relative to one another. 25 Furthermore, it has proven advantageous when the zone designed such as to form a dish features at least one, for example one or two, sunk zones. In t lfis case, the sunk zone is at least 0.2 mm, in particular at least 0.5 mm, for example d.2 to 3 mm, in particular 0.5 to 1.5 mm, deeper than the remaining zones of the diyh. The depth of the sunk zone will typically be in the range of from I to 5 mm and in particular in the range 30 of from 1.2 to 3 mm, whereas the depth in the remaining zones of the dish will typically be in the range of from 0.2 to 2 mm and in particular in the range of from 0.4 to 1.5 mm. The zone designed such as to form a dish will, as a rule, have an area in the range of from 2.5 to 25 cm 2 , in particular in the range of from 4 to 20 cm 2 . 35 The basic shape of the dispenser will typically be rectangular, it beihg possible for the comers to be rounded. In principle, however, oval, circular, triangular, trapezoid, diamond-shaped or polygonal embodiments with more than 4 side are also possible. Preferably, the basic shape of the dispenser has characteristic dim nsions (such as, 5 for example, length of sides, diameter and the like) in the range of rom 1 to 20 cm, in particular in the range of from 1.5 to 10 cm. In the case of a dispeser with a rectangular basic shape, the dimension of the one side of the rectangle will typically be in the range of from 2 to 20 cm, in particular in the range of from 2 5 to 10 cm, and the 5 dimension of the side which is perpendicular thereto will be in the range of from 1 to 10 cm, in particular in the range of from 1.5 to 8 cm. In accordance with the invention, the dispenser features at least o6 e recess in the zone of the films which are bonded to each other. This recess will typicaly feature a circular, 10 oval or polygonal area whose edges are formed by the film materiaI of the deep-drawn film and the planar film. The recess can also be provided with indentations or bulges to ensure better fastening. The extent of the recess along a straight line through the center of the recess area will, as a rule, not be less than 3 mm and preferably not exceed 2 cm. The recess will typically have an area in the range of from 1 to 3 cm 2 . 15 This recess serves for attaching or hanging the dispenser for example to/from branches or shoots of plants. The recess is preferably oval or roun.J, and may additionally be provided with indentations or bulges to ensure better fastening. It has furthermore proved advantageous when the dispenser features a notch which 20 connects the recess to an edge of the dispenser. This notch is her inbelow also referred to as expanding cut and facilitates the fastening of the dispenser for example to branches or shoots of plants. In a preferred embodiment of the invention, the zone designed such as to form a dish 25 features at leastitwo part-zones which are connected to each othe0 and which are arranged on either side of the recess, and connection in between, bereinbelow also referred to as channel. The part-zones together with the connection, in between form a U-shaped or horseshoe-shaped arrangement around the recess. If the zone designed such as to form a dish comprises two part-zones, then the channel linking them will, as 30 a rule, be narrower than the two part-zones and can have a smaller depth in comparison with the former. In this preferred embodiment, the dispenser preferably features an expanding cut. This expanding cut is preferably arranged such that it is arranged between the two 35 part-zones of the chamber, or the zone designed such as to form a! dish, i.e. the two part-zones are located completely on in each case one side of the potch and together with the narrower channel which connects the two part-zones surround the recess. Optionally, one of these part-zones features, in the recess zone, a bulge which is 6 preferably designed such as to form a finger so that the bulge together with the at least two part-zones which are connected to each other largely enclose' the recess. This bulge results in a better hanging stability of the dispenser, in particular when the dispenser features an expanding cut, as described above. 5 In accordance with the invention, the film material of the planar pla tic film is permeable to the pheromone present in the dispenser, i.e. the material of the planar plastic film is chosen such that the pheromone can diffuse across the planar plastic film and can be released into the environment. Suitable plastic films wh ich are permeable 10 to pheromones are known to the skilled worker. Naturally, the type of the plastic material can affect the diffusion rate and thus the release rate of thp pheromone. The plastic material, of the planar plastic film, which is optimal for the pheromone in question depends in the known manner on the nature of the pheroilone. 15 For most pheromones, it has proved advantageous when the plast c material of which the planar film consists is a homo- or copolymer of a C2-Ce-olefin, i particular a homo or copolymer of ethylene. Suitable comonomers are, in principle, all monoethylenically unsaturated monomers which are copolymerizable with the C 2 Ce-C-lefin or the ethylene, with neutral monomers such as vinyl aromatics, for exarnple styrene, vinyl 20 esters of aliphatic C-Cio-carboxylic acids such as vinyl acetate, vinyl propionate and vinyl butyrate, Ci-Cio-alkyl esters of monoethylenically unsaturatell monocarboxylic acids, in particular C-Cio-alkyl esters of acrylic acid and C-C1o-all&/ esters of methacrylic acid, monoethylenically unsaturated nitriles such as adrylonitrile and methacrylonitrile and C3-C-olefins and their mixtures being preferr d. Especially 25 preferred comonomers are the vinyl esters of aliphatic Cr-C 1 o-carboxylic acids, in particular vinyl acetate. Preferably, the 02-Ce-olefin content in the homo- and copolymers of the C2-Ce-olefins is at least 50% by weight, in particular at least 70% by weight. Prefer bly, the ethylene 30 content in the homo- and copolymers of ethylene is at least 50% bt weight, in particular at least 70% by weight, and the comonomer content in the ethylene copolymers is in the range of from I to 50% by weight, in particular in the range of f om 2 to 30% by weight. In a preferred embodiment of the invention, the plastic mate rial of the planar plastic film is a polyethylene, in particular HDPE. 35 Examples of suitable plastic film materials for the planar film are, ir particular, the polyethylenes sold under the trade names Euthylen@, for example Euthylen@ 3020D (uncolored), Lupolen@ for example Lupolen@ 2420 H, and Lufileno, for example Lufilen® 2420 H (brown), from BASF SE, and the ethylene/vinyl acetate copolymers 7 sold under the trade names Greenflex ML, in particular Greenflex@ iL 30 and Greenflex@ ML 40, from Polimeri SA, Italy. Optionally, the planar plastic film features a sealable layer, as explained hereinbelow. 5 The film material of the planar film can be essentially uncolored. Thi means that the film material comprises less than 0.05% by weight and in particular less than 0.01% by weight and especially preferably no color-imparting constituents su4a as inorganic or organic pigments or other dyes. In another embodiment, the film material of the planar 10 film is colored and comprises up to 20% by weight, usually 0.05 to Z% by weight, in particular 0.1 to 1% by weight, of colorant, for example pigments, in particular red and/or brown pigments. The color-imparting constituents which are suitable in accordance With the invention 15 (hereinbelow also referred to as colorant) include not only dyes, but also pigments. The colorant is preferably a pigment. The pigment may take the form of an inorganic or organic pigment. Examples of suitable inorganic color-imparting pigments are white pigments, such as 20 titanium dioxide in its three modifications rutile, anatase or brookite, lead white, zinc white, zinc sulfide or lithopone; black pigments such as carbon black, iron oxide black, iron manganese black or spinel black; chromatic pigments such as hromium oxide, chromium oxide hydride green, cobalt green or ultramarine green, csbalt blue, iron blue, ferric ferrocyanide, ultramarine blue or manganese blue, ultramarine violet or 25 cobalt violet and manganese violet, iron oxide red, cadmium sulfos4lenide, molybdate red or ultramarine red; iron oxide brown, mixed brown, spinel and corundum phases or chromium orange; iron oxide yellow, nickel titanium yellow, chromium titanium yellow, cadmium sulfide, cadmium zinc sulfide, chromium yellow, zinc yellow alkaline earth metal chromates, Naples yellow; bismuth vanadate, color effect pigments such as 30 interference pigments and luster pigments.

Pignjent Green 7, C.L Pigment Blue 15:1, C.1. Pigment Blue 15:3 and C.. Pigment Violet 19. 15 As a rule, the planar plastic film has a thickness in the range of frohn 0.02 to 0.5 mm, in particular in the range of from 0.05 to 0.3 mm. The dispenser according to the invention can be designed to be ut laterally releasing or designed to be bilaterally releasing. If the dispenser is designed unilaterally 20 releasing, then only the planar film is permeable to the pheromone present in the dispenser, or is at least more permeable by a factor of 10 than theldeep-drawn film. In this case, the deep-drawn film may consist of any thermoplasticallj processable plastic material. If the dispenser is designed bilaterally releasing, then both the planar film and the deep-drawn film are permeable to the pheromone present in the dispenser. 25 Bilaterally releasing dispensers are a preferred embodiment of the invention. Examples of suitable plastic materials for the deep-drawn film are the abovementioned homo- and copolymers of C2-Cr-olefins, in particular the homo- or popolymers of ethylene, and furthermore polyesters, polyvinyl chloride, polyvinyli ene chloride, 30 polyacrylonitrile, polystyrene, polycarbonate, polyethylene terephtalate, nylon, coextrudates of the abovementioned polymers, and laminates of t e abovementioned polymers. Preferred plastic materials for the deep-drawn film are the abovem ntioned homo- and 35 copolymers of C2-C6-olefins, in particular the homo- or copolymersiof ethylene. In this case, the deep-drawn film is, as a rule, permeable to the pheromo e, and, accordingly, the dispenser is designed bilaterally releasing. The film material of the deep-drawn film can be essentially uncolord. This means that 9 the film material comprises less than 0.05% by weight and in particular less than 0.01 % by weight and especially preferably no color-imparting constituents uch as inorganic or organic pigments or other dyes. In another embodiment, the film Material of the deep-drawn film is colored and comprises up to 2% by weight, usualy 0.05 to 20% by 5 weight, in particular 0.1 to 1% by weight, of colorant, for example pigments, in particular red and/or brown pigments. As regards the nature of the dolorants, what has been said above applies analogously. As a rule, the deep-drawn plastic film has a thickness in the range ciT from 0.05 to 10 0.5 mm, in particular in the range of from 0.1 to 0.4 mm. The polymer films, i.e. the planar film and the deep-drawn film, may. comprise small amounts of stabilizers conventionally used for such polymers, for example antioxidants, which prevent or reduce aging of the plastic material. Such stabilize s may be present 15 in the polymer in amounts of up to I % by weight. Besides, the film rhaterial may also comprise customary amounts of processing aids, such as antiblockrg agents and lubricant, for example erucamide or oleamide. These substances d6 not have any adverse effects on the properties of the dispenser. 20 The term pheromone is to be understood in the broad sense for the purposes of the invention and comprises not only defined chemical substances, butlalso substance mixtures (also referred to as pheromone bouquet) which are known to affect insect behavior. As a rule, such compounds have 6 to 30 and in particularly to 20 C atoms, and, optionally, 1, 2, 3, 4, 5 or 6 oxygen atoms in the form of hydroyl, carboxylate, 25 ether, keto and/or aldehyde groups, and, optionally, up to 5 halogen atoms, in particular fluorine and/or chlorine atoms. Their molecular weight will preferably not exceed 400 Daltons and is typically in the range of from 100 to 400 'Daltons. The type of pheromone depends in a manner known per se on the target insect species. Suitable pheromones and the respective target insects are known from the literature, 30 for example from "The Pherobase" (http://www.pherobase.com). E amples of pheromones which are preferred in accordance with the invention re: - aromatic, aliphatic and cycloaliphatic aldehydes with 6 to 30 ( atoms, in particular 8 to 20 C atoms, which can be mono- or polyunsat rated, for example 35 1-, 2-, 3-, 4- or 5-fold unsaturated, and which may feature any combination of 1 to 5 halogen atoms, in particular fluorine or chlorine atoms; 1 or '2 hydroxyl groups, acetate groups or keto groups, such as, for example, (E)-2-hdxenal, (E)-4-oxo-2 hexenal, (E,E)-2,4-dimethyl-2,4-hexadienal, (E,E)-2,4-hexadi nal, (Z)-3-hexenal, (Z)-4-oxo-2-hexenal, 1-hexenal, 2-hexenal, 3-((E)-2-hexenoxy)hexanal, 3,5 40 dimethylhexanal, 3-ethoxyhexanal, 3-hydroxybenzaldehyde, 3-hydroxyhexanal, 10 4-hydroxy-3,5-dimethoxybenzaldehyde, 4-hydroxybenzaldehyde, hexanal, (1R,5S)-6,6-dimethylbicyclo[3.1.1]hept-2-ene-2-carbaldehyd4, (E)-2-(2 hydroxyethyl)-6-methyl-2,5-heptadienal, (E)-2-(2-hydroxyeth4lidene)-6-methyl-5 heptenal, (E)-2-heptenal, (E)-2-isopropyl-5-methyl-2-hexenal (E,Z)-2,4 5 heptadienal, (R)-2-((1R,2R, 3 S)-3-methyl-2-vinylcyclopentyl)propanal, (R)-2 ((IS,2S, 3

In the last-mentioned case, the ispenser also comprises, besides the abovementioned pheromones or pheromot e mixtures, one or more inert liquids in a mixture with the pheromones or pheromone !ixtures. In the present context, inert means that the liquid on its own is inactive, bkit does not adversely affect the activity of the pheromone, it also being possible, for the liquid to 10 enhance the activity of the pheromone. Examples are low-molecut r-weight alcohols and ketones having, as a rule, no more than 6 C atoms, such as m ethylbutenol, methylbutynol, aliphatic, cycloaliphatic and aromatic hydrocarbons having 6 to 10 C atoms, and esters of Ci-C-alkanols with saturated C-C6-carboxyk acids such as, for example, their acetates. 15 In accordance with an especially preferred embodiment of the invention, the pheromone present in the dispenser comprises at least one active substance which is selected among mono- or polyunsaturated, for example 1-, 2-, 3- or 4-fold unsaturated, aliphatic alcohols having 6 to 30 C atoms, in particular 8 to 20 C at ms, and their 20 acetates, in particular their monoacetates and diacetates.

The pheromones present in the dispenser may also comprise agents for chemical stabilization purposes, such as, for example, antioxidants and/or U! absorbers. 30 Examples of antioxidants are tocopherols such as a-tocopherol, a-tocopherol palmitate, c:-tocopherol acetate, and alkyl-substituted hydroxybenz nes, hydroquinones and hydroxyanisols such as tert-butylhydroxytolueni, tert butylhydroquinone or tert-butylhydroxyanisole. Examples of UV absorbers are 4,4 diarylbutadiene, cinnamic acid esters, benzotriazoles, in particular t-(2' 35 hydroxyphenyl)benzotriazoles such as, for example, 2-(Z-hydroxy-$'-tert-butyl-5' methylphenyl)-chlorobenzotriazole, hydroxybenzophenones, dipldenylcyanacrylates, oxamides oxalicc acid diamides) and 2-phenyl-1,3,5-triazines. The amount of pheromone or pheromone-comprising liquid (pherorbone and inert 21 liquid) will, as a rule, be such that a sufficient release of the pherorfione over the desired period of use is achieved. Typically, the total amount of ph romone or pheromone-comprising liquid is 0.2 to 5 ml, in particular 0.3 to 3 mi. 5 The present invention also relates to a process for producing a dis enser according to the invention, which comprises: i) providing a deep-drawn plastic film made of a thermoplastic film material which features at least one zone (4) designed such as to form a dish for receiving a pheromone, 10 ii) filling the zone(s) designed such as to form a dish with a phe romone or a pheromone-comprising liquid; iii) sealing the filled zone(s) designed such as to form a dish with a planar plastic film made of a thermoplastic film material by connecting the plan r plastic film with the deep-drawn plastic film, 15 iv) providing the dispenser with a recess in the zone of the past ic films which are connected to each other. To this end, one will, as a rule, in the first step i) form one or more ish-shaped zones (depressions) in the shape desired for the dispenser in a thermoplastically processable 20 plastic film which is suitable for deep-drawing (deep-drawn film) b means of a customary deep-drawing method with heating and, optionally, with applying superatmospheric or subatmospheric pressure. In doing so, one wil, as a rule, form the dish-shaped zones required for a plurality of, for example 2 to 100, in particular 4 to 20, dispensers in the deep-drawn film. Such processes are known to the skilled worker, for 25 example from Saechtling, Kunststoff-Taschenbuch, 26th edition, Cbrl Hanser Verlag, Munich Vienna 1995, pp. 297-305 and G. KOhne in Kunststoff Mas bhinenfOhrer (Johannaber, ed.), 3rd edition, Carl Hanser Verlag, Munich Viennal 1992, pp. 618-634. Thereafter, the dish-shaped zone(s) formed thus is filled, in step ii) with the 30 pheromone or the pheromone-comprising liquid, the amount of pheromone or pheromone-comprising liquid being as a rule chosen such that it corresponds to the desired filling level. In step iii), the filled zone(s) is(are) sealed with a planar plastic film made of a 35 thermoplastic film material. To this end, one will, as a rule, apply the planar plastic film to the deep-drawn film in such a way that the former covers the filled zones and subsequently fix it permanently so that the filled zones are sealed durably. As a rule, fixing is effected by a welding method or a sealing method, where the planar plastic film on the deep-drawn film is durably bonded or sealed to the deep-driwn film. In principle, 22 it is also possible to bond the planar plastic film together with the dbep-drawn film. Such processes are known to the skilled worker, for example from Saechtling, Kunststoff-Taschenbuch, 26th edition, Carl Hanser Verlag, Munich Vienna 1995, pp. 305-325 and G. K0hne in Kunststoff Maschinenf~hrer (Johannabe ed.), 3rd edition, 5 Carl Hanser Verlag, Munich Vienna 1992, pp. 747-810I Welding methods and, in particular, sealing methods are preferred It is preferred to carry out the welding or sealing method such that the planar plastic film is welded or sealed to the deep-drawn plastic film along the edges of the zone designed such as to 10 form a dish, forming a seal. Suitable welding or sealing methods ate, in principle, all methods which are suitable for welding or sealing thermoplastic plstic films. Examples are sealing methods which operate with the application of tempera ure and pressure (hot-sealing) or with the application of ultrasound and pressure (ultrasound sealing methods). 15 If the planar film is connected to the deep-drawn film by a sealing tiethod, it is necessary that the film material of the deep-drawn film is sealable With the film material of the planar film. It may, optionally, therefore be necessary that at least one of the two films has a sealable coating which is sealable to the other film material. If both films 20 consist of a polyolefin, in particular polyethylene, such a seal layer is not necessary since polyolefins are, as a rule, self-sealable. Suitable as sealable layer are all polymers and polymer systems which are sealable, i.e. the seal layer formed can be welded, i.e. durably connected, to another layer when 25 applying sufficient pressures and temperatures. This other layer mby consist of the same polymer as the film material, or of a different polymer. The s alable layer is preferably formed by polymers which are block-resistant at room tEmperature (21*C, 1 bar), i.e. the polymer film formed is not tacky. It is especially preferred that the polymer is block-resistant at up to +50'C. The sealable layer preferably coriists of a polymer 30 which is composed to at least 20% by weight, especially preferably to at least 40% by weight and very especially preferably to at least 60% by weight of t least one Ca-Cr olefin. Such polymers are referred to hereinbelow briefly as polyolfrin. C2-CrOlefins which may be mentioned in particular are ethylene or propylene. P eferred polymers for the sealable layer are homopolymers of the olefins, in particular polyethylene, or 35 polypropylene, or their copolymers. It is especially preferred that thl sealable layer is composed of a polymer which consists to more than 60% by weight of ethylene. The sealable layer especially preferably consists of polyethylene (PE). It is possible to use low-molecular-weight homo- or copolymers of the abovementioned olefins for the sealable layer, for example PE waxes as described in WO 2007/012621. Also suitable 23 are high-molecular-weight polymers, for example polyethylene (PE) which are thermoplastically processable and can be extruded for example in -he form of films. Polyolefins are in particular self-sealable, i.e. the other layer with vkhich durable connection is to be produced is preferably made of the same mate ial. The thickness of 5 the sealable layer, if present, generally amounts to 5 to 100 pm, in particular to 10 to 80 pm and specifically to 15 to 50 pm. Thereafter, the dispenser is provided with a recess in the zone of the plastic'films which are connected to each other. This can be done for example by cutting or punching. The 10 expanding cut can be effected in the same manner. The process according to the invention makes it possible to produce a plurality of dispensers in one pass. In this case, step i) of the process involves simultaneously the making of the number of dish zones required for the number of dispensers to be 15 produced in the pass, in the plastic film used for deep-drawing, filling them with the pheromone or the pheromone-comprising liquid and subsequently sealing them in the above-described manner with the planar film. The dispensers thus made, which are connected to each other, are separated from each other by cutting, with the required number of recesses and, optionally, expanding cuts being made b forehand or 20 simultaneously. The invention will now be described with reference to figures 1 to The description is for illustration purposes only and is not to be construed as limiting the invention to the embodiments shown. 25 Figure 1 shows a top view of the basic shape of a pheromone dispenser according to the invention. Figure 2 shows a top view of a preferred embodiment of a pherom bne dispenser according to the invention. 30 Figure 3 shows a section along line A-A across the embodiment o1 figure 2. The following reference symbols are used in figures 1 to 3: 1 Deep-drawn plastic film 35 2 Seal 3 Edges of the chamber 4 Zone (dish) designed such as to form a dish, or chamber 4a, 4b Part-zones of the dish or chamber 5 Notch/expanding cut 40 6 Recess 24 7 Depression 7a, 7b Sunk part-zones 8 Transition from channel to depression 9 Planar plastic film or film cover 5 10 Bulge The pheromone dispenser shown in figure 1 consists essentially o, a deep-drawn plastic film (1) and a planar plastic film as film cover, between which the pheromone or the pheromone-comprising liquid is enclosed. Since the dispenser s shown in top view, 10 the film cover is not shown in this figure. The pheromone or the pheromone-comprising liquid are not shown either. The deep-drawn plastic film (1) has an essentially rectangular horizontal projection. Owing to manufacturing requirements or use-specific requirements, the corners may be 15 rounded. The zone designed such as to form a dish, here also referred to as chamber (4), serves to receive a pheromone or the pheromone-comprising liquid. The dispenser features a notch (5), which runs from a recess (6) td an outer edge of the dispenser. The recess (6) is, as a rule, oval or round, but may ilso be provided with 20 indentations or bulges to ensure better fastening. The notch (5) divides the dish (4) into two part-zones (4a) and (4b)' which are located on in each case one side of the notch (5) and which are connected to each other by a narrower arc (also referred to as a channel) around the recess (6). The deep-drawn 25 plastic film (1) is connected to the planar plastic film along the edgt s of the dish (4) by means of a seal (2), so that the two plastic films form a durably se led chamber which comprises the pheromone or the pheromone-comprising liquid (not shown). In the specific embodiment of the dispenser shown in figure 2, the Chamber (4) also 30 features two part-zones which are connected to each other by a narrower arc around the recess (6). Moreover, one of the part-zones features a claw-shaped bulge (10), so that the chamber (4) largely encloses the recess (6). Moreover, the chamber (4) features two sunk part-zones (7a) and (7b) in the bottom of the disli. They are located in two adjacent quadrants, between which there is located a notch (5). Each of the 35 sunk part-zones (7a) and (7b) feature a rectangular zone which ruds in parallel with the external edges of the deep-drawn plastic film (1) and the notch (5). A recess (6) is arranged in the remaining two quadrants. It has an oval basic shap and is provided with indentations or bulges to provide better possibilities of fastening.

25 The notch (5) runs above the sunk part-zones (7a) and (7b) in any arc relative to the recess (6). A seal (2) runs along the edges of the chamber. It conncts the deep-drawn plastic film (1) with the planar film cover and thus seals the chamber which comprises the pheromone or the pheromone-comprising liquid (not shown). 5 The cross section along the line A-A across the preferred embodir ent of figure 2, which is shown in figure 3, shows the chamber (4) which is formed by the deep-drawn plastic film (1) and the film cover (9). The chamber (4) features a transition (8) to a depression (7). The chamber (4) is sealed with seals (2) all around, 10 As shown in figure 3, both the planar part of the chamber and the depression are plane-parallel. Only the zones in the transition (8) from chamber to1 depression and the edges (3) of the chamber are excluded. 15 As a rule, a deep-drawn plastic film with a thickness in the range of from 0.05 mm to 0.5 mm and a planar plastic film with a thickness in the range of frdm 0.02 mm to 0.5 mm will be used. The chamber, or the zone designed such as to form a dish, will us1 ally be designed to 20 have a depth in the range of from 0.3 mm to 5 mm, in particular frotn 0.4 to 3 mm, and an area in the range of from 5 cm 2 to 25 cm 2 . In practice, a dispenser according to the invention will be produced as follows: 25 Two rows with in each case 5 of the dish zones shown in figure 2 are made in a thermoplastic film material such as, for example, HD polyethylene with a thickness of, for example, 0.2 mm, by means of deep-drawing under warmth and blow-pressure conditions. The depth of the dish zones in the sunk zones (7a) and (7b) is approximately 2 mm and in the remaining zones of the dish appro imately 1 mm. The 30 total extent of the chamber in the direction of line A-A is approximately 5.3 cm and in the direction of a line perpendicular to A-A 3.8 cm. The chamber (4) is subsequently filled with the pheromone, for example with 0.5 to 1.0 ml of Z9-dod cenyl acetate. The chamber (4) is sealed with a planar plastic film (9) made of a thermoplastic film material such as, for example, HD polyethylene with a thickness of, for example, 0.1 mm by 35 welding the planar plastic film (9) to the deep-drawn plastic film (1) along the edges (3) of the chamber (4) by means of ultrasonic.welding, whereby a seal (2) is formed. A recess (6) is subsequently punched into the dispenser in the zone of the plastic films which are connected to each other, with the recess having two indentations and with the recess having, in the longitudinal axis, a maximum dimension df approximately 26 1.8 cm and a maximum dimension in the axis perpendicular thereto of 1.2 cm. The 10 dispensers formed thus, which are still connected to each other, are separated from each other by cutting, with the expanding cut (5) being made simultaneously. .5 In an analogous manner, it is possible to make for example a colored dispenser, the HD polyethylene for the planar film and the HD polyethylene for thy deep-drawn film being colored in each case with 0.3% by weight of iron oxide pigment.
