Description
i 148290in 148290
Opfindelsen angår en fleksibel beholder til opbevaring og transport af massegods, og som omfatter en bund, sidevægge og løftestropper, samt eventuelt en indvendig sæk af et tæt materiale, hvilken beholder er af 5 den art, som tømmes ved opskæring af dens bund eller sidevæg.BACKGROUND OF THE INVENTION The invention relates to a flexible container for storing and transporting bulk goods, comprising a bottom, side walls and lifting straps, and optionally an inner bag of a dense material, which is of the kind emptied by cutting its bottom or side wall.
Der kendes forskellige udførelsesformer for sådanne beholdere. Hvad angår beholdere med integrerede løftestropper henvises til de norske patentskrifter nr.Various embodiments of such containers are known. Regarding containers with integrated lifting straps, reference is made to Norwegian Patent Specifications no.
1° 136 744 og nr. 138 134. De derfra kendte fleksible be holdere er fortrinsvis fremstillet af et vævet materiale, f.eks. fladvævet eller rundvævet polypropylen.1 ° 136 744 and No. 138 134. The flexible containers known therefrom are preferably made of a woven material, e.g. flat woven or round woven polypropylene.
Bunden af disse beholdere dannes ved sammensyning af materialestykkets nedre dele. Ifølge det sidstnævnte pa-15 tentskrift opskæres den nederste del af materialestykket således, at der derved dannes et antal flige, som ved speciel sammensyning bringes til at danne en dobbelt bund, der er stærkere end den enkelte bund, som beholderen ifølge det førstnævnte patentskrift er udstyret 20 med. Til de fleste formål er disse beholdere forsynet med en indvendig sæk af et tæt materiale, f.eks. poly-ethylenfolie.The bottom of these containers is formed by sewing together the lower parts of the material piece. According to the latter patent, the lower part of the piece of material is cut so as to form a plurality of tabs which, by special sewing, form a double bottom stronger than the single bottom which the container according to the first patent is equipped 20 with. For most purposes, these containers are provided with an inner bag of a dense material, e.g. polyethylene film.
Disse fleksible beholdere har fået udstrakt anvendelse, blandt andet på grund af, at deres konstruktion er meget 25 enkel og bevirker, at materialets styrkeegenskaber udnyttes maksimalt.These flexible containers have been extensively used, partly because their construction is very simple and causes the material's strength properties to be maximized.
Beholderne er beregnet til engangsbrug, og de tømmes ved, at der skæres et hul gennem både det vævede materiale og den indvendige sæk. Som regel hejses beholderen før tøm-30 ningen op ved løftestropperne.The containers are intended for single use and are emptied by cutting a hole through both the woven material and the inner bag. As a rule, the container is emptied prior to emptying at the lifting straps.
Denne tømningsmetode er enkel og praktisk, men i visse tilfælde har den imidlertid en ulempe. Fibermaterialet, 148298 2 som selve beholderen består af, bliver splittet, når der skæres hul i beholderen, og derved kan der blive tilført fiberpartikler til det produkt, der udtømmes fra beholderen. Por visse produkter er kravene til 5 renhed så strenge, at en sådan forurening med fiber partikler ikke kan tolereres.This emptying method is simple and practical, but in some cases it has a disadvantage. The fiber material, which consists of the container itself, is split when holes are cut in the container, thereby providing fiber particles to the product discharged from the container. For certain products, the requirements for purity are so stringent that such pollution with fiber particles cannot be tolerated.
Fødevarer er blandt de produkter, der ikke tillader forurening med fiberpartikler og lignende urenheder. Flere typer fødevarer er velegnede til at blive opbevaret og 10 transporteret i fleksible beholdere, men udstrakt brug af sådanne beholdere til dette formål er hidtil blevet hindret af de forureningsproblemer, der opstår ved tømningen.Foods are among the products that do not allow contamination with fiber particles and similar impurities. Several types of food are suitable to be stored and transported in flexible containers, but extensive use of such containers for this purpose has so far been hampered by the pollution problems that arise during emptying.
Til løsning af disse problemer er det foreslået at 15 binde fibrene med lim, men dette har dog ikke virket efter hensigten.Løsningen er arbejdskrævende, bunden bliver for en tid klæbrig, og ved opskæringen af bunden bliver produktet forurenet med både fiber- og limpartikler. Det har også været foreslået at for-20 syne bunden med tape- eller limbånd, der imidlertid ofte løsner sig, før beholderen skal tømmes, og selv om de har dækket bunden, indtil denne opskæres, har denne metode ikke helt kunnet hindre forurening af produktet.To solve these problems, it has been proposed to bond the fibers with glue, but this has not worked as intended. The solution is labor intensive, the bottom becomes sticky for a time, and when cutting the bottom the product becomes contaminated with both fiber and glue particles. It has also been proposed to provide the bottom with tape or adhesive tape which, however, often loosens before emptying the container, and although they have covered the bottom until cut, this method has not been able to completely prevent contamination of the product. .
25 Selv om ideen med at binde fibrene således ikke havde givet tilfredsstillende resultater, har det dog ifølge opfindelsen overraskende vist sig, at det er muligt at binde fibrene således, at der, når de overskæres, ikke fremkommer løsrevne fiberpartikler, der ville for-30 urene produktet. Dette opnås ifølge opfindelsen ved, at den del af beholderen, som opskæres ved tømning, består af vævede plastfibre eller -tråde lamineret 148298 3 med plastfolie. Det har herved vist sig mest hensigtsmæssigt at fremstille et særskilt bundstykke af lamineret materiale. Eksempelvis kan man laminere et vævet polyolefinmaterialermed polyolefinfolie. Den 5 øvrige del af beholderen, løftestropper og sidevægge kan da fremstilles af vævet materiale. Derved bliver løftestyrken i materialestykkets langsgående tråde udnyttet på samme måde som ved beholdere med integrerede løftestropper. De langsgående trådes forholdvis 10 frie orientering i vævningen kan således bibeholdes, og styrken i hver enkelt tråd udnyttes under løftningen.25 Although the idea of bonding the fibers had thus not yielded satisfactory results, it has, however, surprisingly been found that it is possible to bond the fibers so that, when cut, no detached fiber particles would appear which would dissipate. impure product. This is achieved according to the invention in that the part of the container which is cut by emptying consists of woven plastic fibers or yarns laminated with plastic wrap. It has thus proved most convenient to make a separate base piece of laminated material. For example, a woven polyolefin material can be laminated with polyolefin film. The other 5 parts of the container, lifting straps and side walls can then be made of woven material. Thereby, the lifting force in the longitudinal strands of the material piece is utilized in the same way as in containers with integrated lifting straps. Thus, the relatively free orientation of the longitudinal threads in the weaving can be maintained and the strength of each thread utilized during the lifting.
Ved fremstilling af beholderen kan man gå ud fra et eller flere materialestykker, som syes sammen, således 15 at der dannes løftestropper, der er direkte forlængelser af beholdervæggene, og som derved er integrerede dele af disse.In making the container, one or more pieces of material can be assumed to be sewn together so as to form lifting straps which are direct extensions of the container walls and which are thereby integral parts thereof.
Opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor 20 fig. 1 og 2 viser to materialestykker til fremstilling af en i fig. 3 vist beholder ifølge opfindelsen.The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 and 2 show two pieces of material for the manufacture of one in FIG. 3 according to the invention.
Fig. 1 viser et materialestykke, fortrinsvis af et vævet materiale, og som er udformet med en åbning 3, der i den færdige beholder danner påfyldningsåbning. Materiale-25 stykket 2, der er vist i fig. 2, udgør bunden af den færdige beholder, og det vil kunne bestå af samme materiale som materialestykket 1 med en dertil lamineret plastfolie. Materialestykket 1 syes først sammen med sømme 6 som vist i fig. 3, hvorefter det andet materia-30 lestykke 2 sammensyes med beholderens overdel ved hjælp af sømme 4 og 7, hvorved man får en beholder med integrerede løftestropper 5 og en firkantet bund 2.FIG. 1 shows a piece of material, preferably of a woven material, which is formed with an opening 3 which forms in the finished container filling opening. The material piece 2 shown in FIG. 2, forms the bottom of the finished container and it may consist of the same material as the piece of material 1 with a laminated plastic foil therefor. The piece of material 1 is first sewn together with the seams 6 as shown in FIG. 3, after which the second material piece 2 is sewn to the upper part of the container by means of seams 4 and 7, thereby obtaining a container with integrated lifting straps 5 and a square bottom 2.

Produktionsmæssigt vil det være enklest at fremstille emner til materialestykkerne 1 og 2 hver for sig, og da begge som udgangsmateriale kan være et vævet materiale, er det kun nødvendigt at føre en del af det 5 vævede materiale gennem en lamineringsproces.In terms of production, it will be simplest to produce articles for the pieces of material 1 and 2 separately, and since both as starting material can be a woven material, it is only necessary to pass part of the woven material through a lamination process.
Der kan selvsagt tænkes flere udformninger af den fleksible beholder end den i fig. 3 viste, når blot den del af beholderen, som skæres op til udtømning, består af lamineret materiale, der ikke forurener pro-10 duktet ved udtømningen. For de allerfleste beholdertyper vil det være mest hensigtsmæssigt, at den laminerede del udgør beholderens bund, og at bunden er firkantet. Ved en sådan bundkonstruktion vil beholderen kunne stå stabilt og være egnet til stabling.Of course, more configurations of the flexible container than the one shown in FIG. 3 when only the portion of the container which is cut up for discharge consists of laminated material which does not contaminate the product at the discharge. For most types of containers, it would be most convenient that the laminated portion constitute the bottom of the container and that the bottom is square. In such a bottom construction, the container will be able to stand stable and suitable for stacking.
15 Basismaterialet for bunden 2 behøver ikke nødvendigvis at bestå af vævede plastfibre. Også andre basismaterialer kan anvendes, forudsat at de opfylder kravene med hensyn til styrke etc. Således kan der i stedet for polypropylenfibre anvendes monofilament, bomuld, 20 nylontråd og lignende materialer, som lamineres med plastfolie.The base material for the bottom 2 need not necessarily consist of woven plastic fibers. Other basic materials can also be used provided they meet the requirements for strength etc. Thus, instead of polypropylene fibers, monofilament, cotton, nylon thread and similar materials laminated with plastic film can be used.
Beholderen ifølge opfindelsen kan være udstyret med en indvendig sæk af et tæt materiale, der ikke danner forurenede partikler, når det gennemskæres. I praksis vil 25 plastfolie såsom polyethylen være mest hensigtsmæssigt.The container of the invention may be provided with an inner bag of a dense material which does not form contaminated particles when cut. In practice, plastic film such as polyethylene will be most convenient.
