Description
i DK 175436 B1in DK 175436 B1
Opfindelsen angår en pakning til 1 andbrugskemisk anvendte kemikalier som defineret i krav l's indledning. En pakning af denne art er kendt fra WO 89/12590.The invention relates to a package for 1 chemically used chemicals as defined in the preamble of claim 1. A pack of this kind is known from WO 89/12590.
I øjeblikket opbevares de fleste farlige flydende 5 landbrugskemisk anvendte kemikalier i metaltønder eller, når der er tale om mindre mængder, plastbeholdere.Currently, most hazardous liquid chemicals used in agricultural barrels are stored in metal barrels or, in the case of small quantities, plastic containers.
Farlige kemiske forbindelser, især agrokemiske forbindelser, formuleres på flere forskellige måder. Det er imidlertid særligt hensigtsmæssigt for landmænd at håndtere 10 sådanne forbindelser, når de er i flydende form. Dette letter spredningen af forbindelserne. Der er imidlertid vanskeligheder og ulemper ved håndtering af væsker. Væskerne kan spildes på jorden eller kan udsive på grund af huller i beholderne. Beholderne kan også briste, når de udsættes for 15 mekaniske belastninger.Hazardous chemical compounds, especially agrochemical compounds, are formulated in a variety of ways. However, it is particularly convenient for farmers to handle 10 such compounds when in liquid form. This facilitates the spread of the compounds. However, there are difficulties and disadvantages in handling liquids. The liquids can spill onto the ground or leak due to holes in the containers. The containers can also burst when exposed to 15 mechanical loads.
Det er således vanskeligt at tilvejebringe et indeslutningssystem, som egner sig til anvendelse i landbruget og er sikkert for alle, som håndterer beholderne, og også sikkert for miljøet.Thus, it is difficult to provide a containment system that is suitable for use in agriculture and is safe for everyone handling the containers and also safe for the environment.
20 Det er kendt, at landbrugskemikalier kan være inde holdt i opløselige poser eller pakninger fremstillet af film. Sådanne film kan imidlertid revne og briste og således forårsage spild af de landbrugskemikalier, som de indeholder. I virkeligheden er der mange forskellige mangler, 25 som kan være til stede i film, som fører til svagheder af filmen og følgelig en potentiel udsivningskilde. Tilstedeværelsen af luftbobler, støvpartikler eller andre fremmedlegemer, gelpartikler eller tynde punkter på eller i filmen er alle potentielle svage punkter. Hvis en film med et sådant 30 svagt punkt underkastes megen håndtering eller fysiske belastninger, kan filmen svigte på dette punkt. Dette er især et problem inden for den agrokemiske industri, hvor beholderen kan underkastes grov eller usikker håndtering af distributører eller landmænd.It is known that agricultural chemicals may be contained in soluble bags or packages made of film. However, such films can crack and burst, thus wasting the agricultural chemicals they contain. In fact, there are many different shortcomings, 25 which may be present in films which lead to weaknesses of the film and consequently a potential source of leakage. The presence of air bubbles, dust particles or other foreign matter, gel particles or thin points on or in the film are all potential weak points. If a film with such a weak point is subject to a lot of handling or physical strain, the film may fail at that point. This is especially a problem in the agrochemical industry where the container can be subjected to rough or unsafe handling by distributors or farmers.
35 Svaghederne af film omtalt ovenfor er til stede i en større eller mindre grad i visse typer af film, afhængigt35 The weaknesses of films referred to above are present to a greater or lesser extent in certain types of film, depending

Materialerne, som kan anvendes ved opfindelsen, er 20 vandopløselige eller vanddispergerbare materialer, som er H uopløselige i organiske opløsningsmidler anvendt til opløs - ning eller dispergeririg af de kemikalier, som de anvendes til at indeholde. Egnede materialer omfatter polyethylenoxid H eller methylcellulose., men materialet omfatter fortrinsvis H 25 eller er fortrinsvis afledt af polyvinylalkohol, dvs. delvis eller helt alkoholyseret eller hydrolyseret, f.eks. 40-99%, H fortrinsvis 70-92% alkoholyserede eller hydrolyserede poly- vinylacetatfilm.The materials which can be used in the invention are 20 water-soluble or water-dispersible materials which are H insoluble in organic solvents used for dissolving or dispersing the chemicals which they are used to contain. Suitable materials include polyethylene oxide H or methyl cellulose, but the material preferably comprises H 25 or is preferably derived from polyvinyl alcohol, ie. partially or fully alcoholized or hydrolyzed, e.g. 40-99%, H preferably 70-92% alcoholized or hydrolyzed polyvinyl acetate film.
Lagene af de laminerede film, som anvendes ved opfin- 30 delsen, kan være af det samme materiale eller af forskellige H materialer. Film fremstillet af lag af forskellige materialer H kan have fordelagtige egenskaber. For eksempel kan et indven- digt lag af en pakning gøres mere bestandigt over for det landbrugskemikalie, som den indeholder. Endvidere kan det H 35 udvendige lag af posen vælges til at have én eller flere af H de følgende egenskaber: HJl-Wa r- !! •’'BE ST- _____·· ” T.J-· :...^gi.· -Ly JT---TL - · ,-» DK 175436 B1 5 i. hurtigere opløsning (sammenlignet med en pakning omfattende et indvendigt lag eller et enkelt lag) i vand, ii. opnåelse af forbedrede mekaniske egenskaber omfattende forbedret bestandighed over for mekanisk beska- 5 digelse, iii. opnåelse af forbedret forarbejdningsevne, iv. mindre modtagélighed for relativ fugtighed, v. bestandighed over for frysning og/eller høje temperaturer.The layers of the laminated films used in the invention may be of the same material or of different H materials. Films made of layers of different materials H may have advantageous properties. For example, an inner layer of a gasket can be made more resistant to the agricultural chemical it contains. Furthermore, the H 35 outer layer of the bag can be selected to have one or more of H the following characteristics: HJl-Wa r- !! • '' BE ST- _____ ·· ”TJ- ·: ... ^ gi. · -Ly JT --- TL - ·, -» DK 175436 B1 5 in. Faster resolution (compared to a gasket comprising an inner layer or a single layer) in water, ii. obtaining improved mechanical properties including improved resistance to mechanical damage; iii. obtaining improved processing power, iv. less susceptibility to relative humidity; v. resistance to freezing and / or high temperatures.
10 Et egnet blødgøringsmiddel-indhold i det indvendige lag kan forbedre filmens forseglingsegenskaber og gøre filmen mindre tilbøjelig til at strække sig. Filmen vil således være nemmere at behandle maskinelt og forsegle omkring den farlige væske. Et egnet blødgøringsmiddel-indhold i det 15 udvendige lag af beholderen gør den udvendige overflade mere bøjelig og således mere bestandig over for fysisk beskadigelse forårsaget af lav temperatur eller chok og bevægelse.A suitable plasticizer content in the inner layer can improve the film sealing properties and make the film less prone to stretch. The film will thus be easier to process mechanically and seal around the hazardous liquid. A suitable plasticizer content in the outer layer of the container makes the outer surface more flexible and thus more resistant to physical damage caused by low temperature or shock and movement.
Lagene af den laminerede film kan fremstilles under 20 anvendelse af forskellige metoder, f.eks. ekstrudéring eller støbning. Et laminat fremstillet af lag produceret ved forskellige metoder kan have fordelagtige egenskaber omfattende større bøjelighed, forøget styrke og forøget bestandighed mod strækning. Den forøgede styrke og/eller bestandighed 25 mod strækning kan være i den ene retning af filmen. De laminerede film, som skal anvendes ved den foreliggende opfindelse, anvendes til fremstilling af pakninger, som undgår de tidskrævende og farlige konsekvenser af kendte pakninger, som bliver utætte i fyldningsprocessen eller under efter-30 følgende håndtering på grund af filmdefekter.The layers of the laminated film can be prepared using various methods, e.g. extrusion or casting. A laminate made of layers produced by various methods may have advantageous properties including greater flexibility, increased strength and increased resistance to stretch. The increased strength and / or resistance to stretching may be in one direction of the film. The laminated films to be used in the present invention are used in the preparation of packages which avoid the time-consuming and dangerous consequences of known packages which become leaking in the filling process or during subsequent handling due to film defects.
Som allerede omtalt kan pakningerne ifølge opfindelsen indeholde enten væsker eller geler. De indeholder fortrinsvis en gel.As already mentioned, the packages of the invention may contain either liquids or gels. They preferably contain a gel.
Sådanne geler har fordelagtigt ét eller flere af de .Such gels advantageously have one or more of them.

Det er kendt, at en gel sædvanligvis er et kolloidt materiale, hvori den dispergerede fase foreligger i kombination med den kontinuerlige fase og tilvejebringer et vis-5 kost, gelé-lignende produkt. Det er også et dispergeret system, som typisk består af en høj molekylvægt-forbindelse eller aggregat af små partikler i meget tæt forening med en væske.It is known that a gel is usually a colloidal material in which the dispersed phase is in combination with the continuous phase and provides a certain dietary, jelly-like product. It is also a dispersed system which typically consists of a high molecular weight compound or aggregate of very small particles in very close association with a liquid.
Til fremstilling af en pose skal filmen formes (mu-10 ligvis delvis forsegles) og derpå fyldes med gelen. Generelt er gelerne strømningsdygtige, selv om der er tale om en langsom hastighed på grund af den høje viskositet. En beholder, som anvendes til at indeholde gelerne, kan ikke let tømmes på grund af denne høje gelviskositet {hvilket er en 15 grund til, at gelerne hidtil ikke har været anvendt i landbruget) . Når den er fyldt, skal posen til slut lukkes ved forsegling, sædvanligvis varmeforsegling.To make a bag, the film must be molded (possibly partially sealed) and then filled with the gel. In general, the gels are flowable, although at a slow rate due to the high viscosity. A container used to contain the gels cannot be easily emptied due to this high gel viscosity (which is a reason why the gels have so far not been used in agriculture). When filled, the bag should eventually be closed by sealing, usually heat sealing.
Det følgende eksempel tjener til illustration og skal ikke opfattes som begrænsende for opfindelsens omfang.The following example is illustrative and should not be construed as limiting the scope of the invention.
