Abstract

The container consists of flexible material, essentially of a round fabric made of polyolefins, on whose upper edge in this case four loops (1) are sewn. In this case, the arrangement is such that each loop (1) consists of a relatively wide strip of material, both ends (2, 2') of which overlap the upper container edge (10) and are sewn to the latter spaced apart laterally, and whose central part (3), forming the suspension eye, is drawn together in the manner of a tape. By this means, loops are formed in a relatively simple manner, adjoining which loops there is a large number of warp threads of the round fabric and which in this way have a high load-bearing capacity, the resistance to tensile force at the loops themselves being increased by being drawn together. <IMAGE>

Description

Die vorliegende Erfindung betrifft einen Container aus fle­xiblem Material, im wesentlichen aus einem Rundgewebe aus Polyolefine.The present invention relates to a container made of flexible material, essentially a round fabric made of polyolefins.

In vielen Anwendungsbereichen haben sich Säcke aus einem Rundgewebe als geeignetes Verpackungsmittel bewährt, wobei sich neben Jute als Sackmaterial insbesondere Polyolefine, etwa Polypropylen (PP) oder Plyäthylen (PE) durchgesetzt ha­ben, die in Form von flachen Bändchen verwoben werden. Säcke aus solchen Geweben sind chemikalienbeständig, wasserunemp­findlich, hygienisch, atmungsaktiv, unverrottbar u.a.In many areas of application, sacks made from a round fabric have proven to be a suitable packaging material, whereby in addition to jute, polyolefins, such as polypropylene (PP) or polyethylene (PE), which have been woven in the form of flat ribbons, have become established as the sack material. Sacks made from such fabrics are chemical-resistant, water-insensitive, hygienic, breathable, rot-proof, etc.

Um solche gewobenen Säcke auch für kornfeinste und hygro­skopische Schüttgüter, wie Zement, verwenden zu können, ist es bekannt, im Websack einen Innensack aus feuchtigkeitsun­durchlässigem Material, beispielsweise eine geblasene Poly­äthylenfolie, einzubringen.In order to be able to use such woven sacks also for the finest grain and hygroscopic bulk goods, such as cement, it is known to insert an inner sack made of moisture-impermeable material, for example a blown polyethylene film, in the weaving sack.

In vielen Fällen besteht nun der Wunsch, solche bekannten Säcke mit oder ohne Innensack auch in Grössenordnungen des Containerbereiches mit einem Füllgutgewicht von beispiels­weise 1000 und mehr Kilogramm verwenden zu können. Von der Reissfestigkeit der für solche Säcke verwendeten Materialien her bestehen hierbei in der Regel keine Probleme, hingegen werden der Belastbarkeit solcher Container durch die bisher bekannten, in der Regel angenähten Schlaufen zum Transport der Container mittels Hebeeinrichtungen, wie Kran und dgl., enge Grenzen gesetzt, da die bisherigen schmalen Schlaufen aus Polyamide-Geweben o.dgl. das Gewicht auf nur wenige Kettfäden bertragen können. Entsprechend wurden die Schlaufen schon untergurtet, was aber mit dem damit verbundenen Material- und Herstellungsaufwand nicht mehr wirtschaftlich ist. Ge­rade aber letzteres ist bei Massenartikeln, wie dies die hier infrage stehenden Verpackungsmittel darstellen, von grösster Bedeutung.In many cases there is now a desire to be able to use such known bags with or without an inner bag, even in the order of magnitude of the container area, with a filling weight of, for example, 1000 and more kilograms. There are generally no problems with the tensile strength of the materials used for such sacks, however, the load capacity of such containers is limited by the previously known, usually sewn-on loops for transporting the containers by means of lifting devices, such as a crane and the like , because the previous narrow loops made of polyamide fabrics or the like. can transfer the weight to just a few warp threads. Accordingly, the loops have already been strapped, but this is no longer economical with the associated material and production costs. But the latter in particular is of the greatest importance in the case of mass articles, as represented by the packaging materials in question here.

Aufgabe der Erfindung ist es nun, einen Container der vor­genannten Art zu schaffen, dessen Schlaufen die Zugkraft beim Anheben der Last auf wesentlich mehr Kettfäden über­tragen ohne die Notwendigkeit von Verstärkungen, Untergur­tungen u.a. und bei kostengünstiger Herstellung.The object of the invention is now to provide a container of the aforementioned type, the loops of which transmit the tensile force when lifting the load to significantly more warp threads without the need for reinforcements, lower straps and the like. and with inexpensive production.

Dies wird erfindungsgemäss dadurch erreicht, dass jede Schlaufe aus einem relativ breiten Materialstreifen besteht, dessen beide Enden den oberen Container-Rand überlappen so­wie mit diesem seitlich distanziert voneinander vernäht sind und dessen die Aufhängeöse bildender Mittelteil bandartig zu­sammengenommen ist.This is achieved according to the invention in that each loop consists of a relatively wide strip of material, the two ends of which overlap the upper edge of the container and are sewn laterally spaced apart therefrom, and the central part of which forms the suspension eye and is tied together in a band.

Wie ohne weiteres erkennbar, liegt nun der Materialstreifen mit seinen Enden breitflächig auf einer grossen Anzahl Kett­fäden auf, so dass sich auch eine entsprechend hohe Tragfäh­igkeit ergibt, wobei sich die Zugfestigkeit an der Schlaufe selbst durch das bandartige Zusammennehmen zusätzlich erhöht. Die grossflächigen Enden des Materialstreifens lassen sich zudem gut vernähen, sodass sich ein sehr kostengünstiger Con­tainer ergibt. Es kann dadurch ein leichteres Gewebe für den Containermantel als bisher für gleiche Belastungen verwendet werden. Zweckmässige Ausgestaltungen des erfindungsgemässen Contai­ners ergeben sich dann, wenn der Mittelteil jeder Schlaufe durch einfaches oder mehrfaches Verdrehen des Materialstrei­fens vor dessen Annähen an den oberen Container-Rand band­artig zusammengenommen ist, oder aber, wenn der Mittelteil jeder Schlaufe durch Raffen oder Falten bandartig zusammen­genommen ist, wobei dann vorzugsweise der bandartig zusammen­genommene Mittelteil wenigstens eine, vorzugsweise mittige Quernaht aufweist, um ein Aufspringen des bandartigen Mittel­teiles zu verhindern.As can easily be seen, the ends of the material strip now lie on a large number of warp threads over a large area, so that there is also a correspondingly high load-bearing capacity, the tensile strength on the loop itself being additionally increased by the band-like pulling together. The large ends of the material strip can also be sewn well, resulting in a very inexpensive container. As a result, a lighter fabric can be used for the container jacket than before for the same loads. Appropriate configurations of the container according to the invention result when the middle part of each loop is pulled together like a band by simply or repeatedly twisting the material strip before it is sewn to the upper container edge, or when the middle part of each loop is pulled together like a band by gathering or folding, in which case the band-like central part preferably has at least one, preferably central transverse seam in order to prevent the band-like center part from popping open.

Vorteilhaft kann es ferner sein, wenn der eine Schlaufe bil­dende Materialstreifen aus einem flachgelegten Rundgewebe aus Polyolefine besteht.It can also be advantageous if the material strip forming a loop is made from a flat, round fabric consists of polyolefins.

Hierbei ist es vorteilhaft, wenn das Rundgewebe aus Poly­propylen- oder Polyäthylen-Bändchen besteht.It is advantageous if the round fabric consists of polypropylene or polyethylene tapes.

Weitere Vorteile ergeben sich aus der nachfolgend beschrie­benen beispielsweisen Ausführungsform des Erfindungsgegen­standes anhand der Zeichnung, welche einen Container in schaubildartiger Darstellung zeigt.Further advantages result from the exemplary embodiment of the subject matter described below with reference to the drawing, which shows a container in a diagram-like representation.

Der dargestellte Container aus flexiblem Material besteht hier im wesentlichen aus einem Rundgewebe 20 aus Polypropylen Bändchen, welche Kettfäden 6 und Schussfäden 5 bilden. Ein vorgesehener Innensack aus beispielsweise einer Polyäthylen­folie ist erkennbar durch einen Einlass 23 resp. Auslass 26, welche je ein Ventil 24 eines Deckblattes 21 resp. Ventil 25 eines Bodenblattes 22 durchdringen. Die Ventile sind mit­tels Schnur 28 verschliessbar. Deckblatt 21 und Bodenblatt 22 sind Bahnen einer Folie oder eines Gewebes. Container dieser Art sind ansich bekannt und weisen am oberen Rand zwei oder mehr Schlaufen auf.The container shown made of flexible material consists essentially of a round fabric 20 made of polypropylene tapes, which form warp threads 6 and weft threads 5. An intended inner bag made of, for example, a polyethylene film can be recognized by an inlet 23 or. Outlet 26, each of which a valve 24 of a cover sheet 21 or. Penetrate valve 25 of a bottom sheet 22. The valves can be closed by means of a cord 28. Cover sheet 21 and bottom sheet 22 are webs of a film or a fabric. Containers of this type are known per se and have two or more loops on the upper edge.

Erfindungsgemäss ist hier nun jede Schlaufe 1 aus einem rela­tiv breiten Materialstreifen aus einem Gewebe, einem flachge­legten Rundgewebe oder dgl. der vorgenannten Materialien ge­bildet, dessen beide Enden 2 resp. 2′ den oberen Container-­ Rand 10 überlappen sowie mit diesem seitlich distanziert von­einander mit einigen Nähten 7 etwa parallel den Schussfäden 5 vernäht sind, wie das die Darstellung deutlich macht.According to the invention, each loop 1 is now formed from a relatively wide strip of material from a woven fabric, a flat circular fabric or the like. The aforementioned materials, the two ends of which are 2 and. 2 ′ the upper container Overlap the edge 10 and are sewn laterally spaced apart from each other with a few seams 7 approximately parallel to the weft threads 5, as is made clear by the illustration.

Hierbei ist weiter der die Aufhängeöse bildende Mittelteil 3 bandartig zusammengenommen, um diesen Teil aufhaken zu können. Dies kann, wie dargestellt, durch einfaches oder auch mehr­faches Verdrehen des Materialstreifens vor dessen Annähen an den oberen Container-Rand erfolgen oder aber auch durch Raf­fen oder Falten. Eine mittige Quernaht 4 verhindert dann ein Aufspringen.In this case, the central part 3 forming the suspension eye is further put together like a band in order to be able to hook this part up. As shown, this can be done by simply or repeatedly twisting the material strip before sewing it onto the upper container edge, or else by gathering or folding. A central transverse seam 4 then prevents it from jumping open.

Damit wird unter Aufrechterhaltung einer schmalen, band- oder seilförmigen Aufhängeöse eine grosse, eine Vielzahl Kettfä­den abdeckende Befestigungsfläche erreicht, welche höchste Tragfähigkeit bewirkt bei vergleichsweise geringem Material- und Herstellungsaufwand, so dass alle vorgenannten Anforde­rungen an solche Container vollumfänglich und optimal er­füllt sind.Thus, while maintaining a narrow, band-shaped or rope-shaped suspension eyelet, a large fastening surface covering a large number of warp threads is achieved, which results in maximum load-bearing capacity with comparatively low material and manufacturing expenditure, so that all of the aforementioned requirements for such containers are fully and optimally met.

Hierbei hat sich eine Breite für den eine Schlaufe bildenden Materialstreifen von mindestens 90 mm oder mehr als zweck­mässig gezeigt.A width of at least 90 mm or more for the material strip forming a loop has been found to be expedient.

Grösste Elastizität bei höchster Tragkraft wird zudem erreicht, wenn das Rundgewebe des Containermantels und/oder des die Schlaufen bildenden Materialstreifens zwei- oder mehrfach übereinanderliegende Kettfäden aufweist.The greatest elasticity with the highest load-bearing capacity is also achieved if the round fabric of the container jacket and / or the material strip forming the loops has warp threads lying two or more times one above the other.
