Abstract

A flexible container (1) for transporting or stocking lamps of material, dry bulk materials, ammunition, gases or liquids and the like is shaped as a hose having openings hermetically sealed by straight or linear clamping elements (14). The clamping elements are shaped as toothed racks, so that hoses with relatively large openings can be sealed with relatively short clamping elements. The clamping elements can be held by a tensioning element (31, 32, 33) in a container (10) or in a frame at a certain distance from the ground.

Description

Die Erfindung bezieht sich auf einen flexiblen Behälter aus Kunststoff- oder Elastomermaterial gemäß dem Oberbegriff des Anspruchs 1. Solche Behälter sind allgemein bekannt.The invention relates to a flexible container made of plastic or elastomer material according to the preamble of claim 1. Such containers are generally known.

Es ist beispielsweise bekannt, in einem Container Flüssigkeiten zu transportieren, und zu diesem Zweck ist der Container mit einem dicht verschließbaren Innenbehälter versehen, der aus flexiblen Kunststoffmaterial gebildet ist. Dieser Behälter nimmt im gefüllten Zustand im wesentlichen die Form des Innenraums des Containers an. Um zu verhindern, daß in dem Behälter befindliche Flüssigkeit beim Transport unerwünschte Bewegungen (Schlinger- oder Schwappbewegungen) durchführt, werden Netze oder Gurte so über dem Container befestigt, daß diese den Kunststoffbehälter nach oben hin in seiner oberen Erstreckung und Bewegungsmöglichkeit festlegen.For example, it is known to transport liquids in a container, and for this purpose the container is provided with a tightly closable inner container which is formed from flexible plastic material. When filled, this container essentially assumes the shape of the interior of the container. In order to prevent the liquid in the container from carrying out undesired movements (roll or slosh movements) during transport, nets or straps are fastened over the container in such a way that they fix the plastic container upwards in terms of its upper extent and possibility of movement.

Wegen der Größe der üblichen Container (die Stirnflächen haben Abmessungen im Bereich von einigen Metern, während die Länge ca. 10 m beträgt) ist die Herstellung von für Flüssigkeiten geeigneten Behältern problematisch, abgleich sie mit der Quaderform des Containers im wesentlichen übereinstimmen. Hinzu kommt noch, daß der Kunststoffbehälter während des Transports erheblichen Beanspruchungen durch die Bewegung der Flüssigkeit ausgesetzt ist. Man denke beispielsweise daran, daß ein Container auf einem Güterwagen transportiert wird, der seinerseits von einem Abrollberg abläuft oder abgestoßen wird und ungedämpft auf einen Prellbock aufläuft. In diesem Falle können solche Massenkräfte durch die Flüssigkeit entstehen, daß der Kunststoffbehälter und der Container zerstört werden können.Because of the size of the usual containers (the end faces have dimensions in the range of a few meters, while the length is approximately 10 m), the production of containers suitable for liquids is problematic, although they essentially match the cuboid shape of the container. In addition, the plastic container is exposed to considerable stresses caused by the movement of the liquid during transport. Consider, for example, that a container is transported on a freight wagon, which in turn runs or is pushed off a roll-off mountain and runs undamped onto a buffer. In this case, such mass forces can arise from the liquid that the plastic container and the container can be destroyed.

Die Erfindung befaßt sich mit dem Problem, die Herstellung von für Container geeignete Flüssigkeitsbehälter zu verbessern, darüber hinaus soll aber auch eine solche Ausgestaltung des Behälters gefunden werden, daß Transportbeanspruchungen nicht zur Zerstörung des Kunststoffbehälters und Metallcontainers führen.The invention is concerned with the problem of improving the production of liquid containers suitable for containers, but moreover such a configuration of the container is also to be found that transport stresses do not lead to the destruction of the plastic container and metal container.

Erreicht wird dies durch einen flexiblen Behälter gemäß Anspruch 1. Weitere Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen definiert.This is achieved by a flexible container according to claim 1. Further developments of the invention are defined in the dependent claims.

Der Behälter wird aus einem geeigneten Material, welches auch mehrschichtig sein kann, durch Zusammenfügen von Längsstreifen zu einem Schlauch hergestellt. Diese Art der Herstellung ist technisch gelöst, es können genügend lange Streifen, beispielsweise mit Hilfe der Hochfrequenzschweißung von Bahnen aus polarem Kunststoffmaterial zu einem Schlauch zusammengebracht werden.The container is made of a suitable material, which can also be multi-layered, by joining longitudinal strips into a tube. This type of production is technically solved; strips of sufficient length can be brought together to form a tube, for example with the aid of high-frequency welding of sheets of polar plastic material.

Die beiden Öffnungsseiten eines solchen Schlauchs werden sodann mit zwei zueinander passenden Klemmverbindungsteilen miteinander verbunden. Wählt man einen Schlauch, der einen möglichst großen Teil des Innenraums eines Containers ausfüllt, so wäre bei geradliniger Verbindung des Randes einer Öffnung ein Klemmverbindungsteil notwendig, der länger ist als der Container breit ist. Daher werden bei einer Ausführungsform der Erfindung die beiden Klemmteile mit Klemmbacken ausgebildet, die eine gewellte Oberfläche haben. Verwendet man beispielsweise zahnstangenartige Klemmbacken mit einem Zahnwinkel von 60°, so kann durch das Hin- und Herlegen des Randes des Schlauches über die gewellte Oberfläche der Klemmbacken eine Klemmleiste verwendet werden, die nur etwa ein Viertel des Umfanges des Schlauches lang ist. Bei geeigneter Ausgestaltung wird gemäß der Erfindung einesolche Länge gewählt, so daß die Klemmverbindungsteile zu beiden Seiten in die Türöffnungen des Containers genau hineinpassen bzw. etwas kleiner sind. Nachdem der schlauchförmige Behälter auf diese Art und Weise zu beiden Seiten verschlossen worden is, werden die Klemmverbindungsteile in einer bestimmten Höhe oberhalb der Bodenfläche des Containers im Rahmen der Türöffnungen des Containers mit Hilfe von Spreizteilen oder dergl. befestigt. Diese Befestigung oberhalb der Bodenfläche des Containers führt dazu, daß einerseits der gefüllte Behälter immer eine bestimmte durch die Vorspannung des Behälters festgelegte Form hat, so daß Schwingungen während des Transports entgegengewirkt werden kann und keine Zerstörung des Behälters eintritt. Es kommt noch hinzu, daß durch geeignete Befestigungen die untere Hälfte des schlauchförmigen Behälters ebenfalls in einer gespannten Lage ist, so daß ein restloses Entleeren des schlauchförmigen Behälters möglich ist.The two opening sides of such a hose are then connected to one another with two mutually fitting clamping connection parts. If you choose a hose that fills as large a part of the interior of a container as possible, a straight connection of the edge of an opening would require a clamp connection part that is longer than the container is wide. Therefore, in one embodiment of the invention, the two clamping parts are formed with clamping jaws that have a corrugated surface. If, for example, rack-like jaws with a tooth angle of 60 ° are used, a clamping strip that is only about a quarter of the circumference of the tube can be used by moving the edge of the tube back and forth over the corrugated surface of the jaws. In a suitable embodiment, such a length is chosen according to the invention so that the clamping connection parts on both sides fit exactly into the door openings of the container or are somewhat smaller. After the tubular container has been closed on both sides in this way, the clamp connection parts are attached at a certain height above the bottom surface of the container in the frame of the door openings of the container with the aid of expansion parts or the like. This attachment above the bottom surface of the container means that, on the one hand, the filled container always has a certain shape, determined by the pretensioning of the container, so that vibrations can be counteracted during transport and the container is not destroyed. There is also the fact that the lower half of the tubular container is also in a tensioned position by suitable fasteners, so that a complete emptying of the tubular container is possible.

Der schlauchförmige Behälter muß nicht aus zwei einander gleichen oberen und unteren Hälften gebildet worden sein. Vielmehr ist eine "asymmetrische" Ausbildung vorteilhaft, weil durch Ausbildung des unteren Teils in Form einer Wanne und durch Ausbildung des oberen Teils in Form einer gespannten Membran, ein Behälter gebildet wird, der nach Füllung mit der zu transportierenden Flüssigkeit kaum Schwingungsbeanspruchungen beim Transport ausgesetzt ist.The tubular container need not have been formed from two identical upper and lower halves. Rather, an "asymmetrical" design is advantageous because by designing the lower part in the form of a trough and designing the upper part in the form of a tensioned membrane, a container is formed which, after being filled with the liquid to be transported, is hardly exposed to vibrational stresses during transport .

Der Behälter muß nicht notwendigerweise aus einer einzigen schlauchförmigen Hülle bestehen. Vielmehr kann mit einer mehrhülligen Ausbildungsform erreicht werden, daß gefährliche Güter mit Hilfe eines flexiblen Behälters gemäß der Erfindung transportiert oder gelagert werden können. Hierbei nimmt die relativ dickwandige Außenhülle im wesentlichen die mechanischen Beanspruchungen auf, während die relativ dünne Innenhülle in Form einer Blase dazu dient, besonders aggressive oder gefährliche Medien dicht zu umschließen. Beispielsweise kann für die Innenschicht eine durch Blasformgebung hergestellte Blase verwendet werden, die aus einem Material besteht, das zum Transport der betreffenden gefährlichen Flüssigkeit geeignet ist. Diese Innenblase braucht nur eine geringe mechanische Festigkeit zu haben, da die Außenhülle dem Behälter insgesamt die für die Aufnahme und den Transport der Flüssigkeit erforderliche Festigkeit verleiht. Daher kann für die Außenhülle ein Material verwendet werden, welches vor allem die geforderten mechanischen Eigenschaften besitzt, ohne daß auf die Aggressivität des zu transportierenden Mediums Rücksicht genommen werden muß.The container need not necessarily consist of a single tubular casing. Rather, it can be achieved with a multi-envelope form of training that dangerous goods can be transported or stored using a flexible container according to the invention. Here, the relatively thick-walled outer casing essentially absorbs the mechanical stresses, while the relatively thin inner casing in the form of a bubble serves to tightly enclose particularly aggressive or dangerous media. For example, a bubble made by blow molding, which consists of a material that is suitable for transporting the dangerous liquid in question, can be used for the inner layer. This inner bladder need only have a low mechanical strength, since the outer shell of the container as a whole has the strength required for the absorption and transport of the liquid gives. Therefore, a material can be used for the outer shell, which above all has the required mechanical properties, without having to take into account the aggressiveness of the medium to be transported.

Bei einer Beschädigung des Äußeren eines flexiblen Behälters gemäß der Erfindung kann dieser erneut verwendet werden, wenn in den Innenraum eine geschlossene Blase eingebracht wird.If the exterior of a flexible container according to the invention is damaged, it can be used again if a closed bladder is introduced into the interior.

Es ist weiterhin möglich, den schlauchförmigen Behälter beim Zusammenfügen der Randöffnungen mit einer Unterlage zu versehen. Diese Unterlage wird zusammen mit den beiden zusammengelegten Hälften der Öffnung zwischen die Klemmbacken gelegt und dort befestigt. Auf diese Weise kann dem Behälter eine noch größere mechanische Belastbarkeit oder Festigkeit verliehen werden. Es kann auch erreicht werden, daß gerade der besonders beanspruchte Teil des schlauchförmigen Behälters gegenüber dem Boden geschützt wird, insbesondere wenn der Behälter gemäß der Erfindung in eine Mulde im Erdreich verlegt wird.It is also possible to provide the tubular container with a base when joining the edge openings. This underlay is placed together with the two folded halves of the opening between the clamping jaws and fastened there. In this way, the container can be given an even greater mechanical strength or strength. It can also be achieved that the particularly stressed part of the tubular container is protected from the ground, especially if the container according to the invention is laid in a trough in the ground.

In den Figuren ist mit strichpunktierten Linien der Umriß eines Containers 10 wiedergegeben. Im Container 10 befindet sich ein schlauchförmiger flexibler Behälter 11, welcher durch die Seitenflächen des Containers eine seitlich abgeplattete Form angenommen hat. Der Behälter 11 hat jedoch ansonsten im wesentlichen eine zylindrische Schlauchform.In the figures, the outline of a container 10 is shown with dash-dotted lines. In the container 10 there is a tubular flexible container 11 which has assumed a laterally flattened shape due to the side surfaces of the container. However, the container 11 is otherwise essentially cylindrical in shape.

Die beiden einander gegenüberliegenden Öffnungen des Schlauches sind mit geradlinigen Klemmverbindungsteilen 14 dicht verschlossen.The two opposite openings of the hose are tightly closed with straight clamping connection parts 14.

In der Fig. 1 ist oben eine Einfüllmöglichkeit mit Hilfe eines Schlauches bzw. einer Öffnung 12 gezeigt.1 shows a possibility of filling using a hose or an opening 12.

Am schlauchförmigen Behälter 11 sind in Längserstreckung mehrere Befestigungsteile, nämlich Gurte 13, angebracht, die mit ihrem freien Ende im unteren Bereich des Containers 10 festgelegt sind.A plurality of fastening parts, namely straps 13, are attached to the tubular container 11 in the longitudinal direction and are fixed with their free end in the lower region of the container 10.

Die Fig. 2 und 3 zeigen den Behälter 11 im Container 10 im geleerten Zustand. In der Ausführungsform nach Fig. 2 befindet sich die Beschickungs- und Entnahmevorrichtung 12 oben, wohingegen in der Fig. ein Ablaufstutzen 15 unten angeordnet ist.2 and 3 show the container 11 in the container 10 in the emptied state. In the embodiment according to FIG. 2, the loading and unloading device 12 is located at the top, whereas in the figure a drain pipe 15 is arranged at the bottom.

In den Fig. 1 bis 3 ist zu erkennen, daß die Befestigungsteile 14 in einer gewissen Höhe oberhalb der Bodenfläche des Containers 10 an dem Öffnungsrahmen des Containers 10 befestigt sind. Es ist ersichtlich, daß hierdurch der Behälter 11 auch im mit Flüssigkeit gefüllten Zustand eine Form annimmt, die hinsichtlich der auftretenden Schwingungsbeanspruchungen günstig ist.1 to 3 it can be seen that the fastening parts 14 are fastened to the opening frame of the container 10 at a certain height above the bottom surface of the container 10. It can be seen that in this way the container 11 also assumes a shape in the liquid-filled state which is favorable with regard to the vibrational stresses that occur.

In den Fig. 4 und 5 ist ein Klemmverbindungsteil 14 gezeigt. Dieser besteht aus zwei länglichen zueinander passenden Klenimbakken 20 und 21. Allerdings sind die miteinander zusammenwirkenden Flächen der Klemmbacken 20 und 21 nicht eben ausgebildet, sondern sie haben zueinander passende gewellte Oberflächen. Die beiden Klemmbakken 20 und 21 nehmen, wie in Fig. 5 zu erkennen, den oberen und unteren Randteil eines schlauchförmigen Behälters 12 auf. Werden die mit 22 bezeichneten Schraubverbindungen angezogen, so werden die beiden gegenüberliegenden Innenflächen der schlauchförmigen Hülle 11 gas- und flüssigkeitsdicht aufeinander gepreßt.4 and 5, a clamp connection part 14 is shown. This consists of two elongated Klenimbakken 20 and 21. However, the interacting surfaces of the jaws 20 and 21 are not flat, but they have matching corrugated surfaces. As can be seen in FIG. 5, the two clamping jaws 20 and 21 receive the upper and lower edge part of a tubular container 12. If the screw connections designated by 22 are tightened, the two opposite inner surfaces of the tubular casing 11 are pressed against one another in a gas-tight and liquid-tight manner.

Die Fig. 6 gibt diese Verhältnisse in natürlicher Größe zu erkennen, wobei rechts der schlauchförmige Behälter 11 selbst zu denken ist. Dieser geht von dorther in die im wesentlichen zylindrische Form der Fig. über. Die Stoßenden des Behälters 11 sind links zu erkennen, sie befinden sich in dem Zusammendrückbereich zwischen den beiden Klemmbacken 20 und 21. Es ist zu erkennen, daß anstelle der beiden in der Fig.6 gezeigten Ränder eines einzigen schlauchförmigen Behälters 11 auch mehrere ineinander angeordnete Behälter in gleicher Weise zwischen den Klemmbacken 20 und 21 verklemmt werden können.FIG. 6 shows these conditions in natural size, with the tubular container 11 itself being conceivable on the right. From there it merges into the essentially cylindrical shape of FIG. The butt ends of the container 11 can be seen on the left, they are located in the compression area between the two clamping jaws 20 and 21. It can be seen that instead of the two edges of a single tubular container 11 shown in FIG. 6, there are also several containers arranged one inside the other can be clamped in the same way between the jaws 20 and 21.

In Fig. 4 aber auch in Fig. 6 und 7 sind Spannteile 33 zu erkennen. Es handelt sich hierbei um einen bolzenartigen Teil 32, der in seinem äußeren Bereich mit einem Sechskantkopf versehen ist. Der Gewindeteil des Bolzens 32 ist in ein passendes Gewindestück 31 eingeschraubt. Teile 31 sind an den beiden Stirnendseiten eines Klemmverbindungsteils 14 befestigt. Es ist insbesondere nach den Fig. 4 und 7 ersichtlich, daß durch Drehen des Bolzens 32 die axiale Gesamtlänge des Klemmverbindungsteils 14 vergrößert oder verkleinert werden kann. Nachdem nämlich die Abdichtung der Öffnungen des schlauchförmigen Behälters 11 durch Zusammenpressen der beiden Klemmbacken 20 und 21 vorgenommen worden ist, werden beide Klemmteile 14 in die Türpfostenöffnungen des Containers 10 verbracht und die Bolzen 32 soweit herausgedreht, daß eine feste Halterung der Klemmverbindungsteile 14 im Türrahmen des Containers 10 erreicht wird (gezeigt in den Fig. 1 bis 3).4 but also in FIGS. 6 and 7 clamping parts 33 can be seen. This is a bolt-like part 32, which is provided with a hexagon head in its outer region. The threaded part of the bolt 32 is screwed into a suitable threaded piece 31. Parts 31 are fastened to the two end faces of a clamping connection part 14. It can be seen in particular from FIGS. 4 and 7 that the total axial length of the clamping connection part 14 can be increased or decreased by rotating the bolt 32. After the openings of the tubular container 11 have been sealed by pressing the two clamping jaws 20 and 21 together, both clamping parts 14 are placed in the door jamb openings of the container 10 and the bolts 32 are screwed out so far that a firm mounting of the clamping connection parts 14 in the door frame of the Containers 10 is reached (shown in FIGS. 1 to 3).

Die Fig. 8 läßt erkennen, wie die Gurte 13 an dem schlauchförmigen Behälter 11 befestigt worden sind. Ein Kunststoffteil 44 ist nämlich eine Schlaufe bildend mit dem Behälter 11 verschweißt, wobei in die Schlaufe eine Öse oder D-Ring 45 eingehängt ist. An der Öse ist der Gurt 13 befestigt, welcher an seinem unteren Ende einen Haken 46 aufweist. Die Gurte 13 können längenverstellbar ausgebildet sein, sie werden im unteren Bereich des Containers 10 so festgelegt, daß der schlauchförmige Behälter 11 im Hinblick auf mögliche Transportschwingungen der enthaltenden Flüssigkeit festgelegt wird.Fig. 8 shows how the straps 13 have been attached to the tubular container 11. A plastic part 44 is namely welded to form a loop with the container 11, an eyelet or D-ring 45 being suspended in the loop. The belt 13 is fastened to the eyelet and has a hook 46 at its lower end. The straps 13 can be adjustable in length, they are fixed in the lower region of the container 10 so that the tubular container 11 is fixed with regard to possible transport vibrations of the liquid contained.

Als Werkstoffe für den schlauchförmigen Behälter kommen Kunststoffe oder Elastomere in Frage, wobei diese eine oder mehrere Gewebeschichten von beiden Seiten umschließen und durchdringen. Beispielsweise können Elastomere (Nitril-, Butylgummi und dergl.) aber auch Thermoplaste (PVC, PP, PE) verwendet werden. Werden Materialien mit polarem Charakter verwendet, so können die einzelnen Bahnen durch Hochfrequenz miteinander verschweißt werden.As materials for the tubular container, plastics or elastomers come into question, these enclosing and penetrating one or more fabric layers from both sides. For example, elastomers (nitrile, butyl rubber and the like) but also thermoplastics (PVC, PP, PE) can be used. If materials with a polar character are used, the individual webs can be welded together by high frequency.

Anstelle des in den Fig. 4 und 5 gezeigten Profils der Klemmbacken können irgendwelche andere labyrinthartige Dichtmöglichkeiten verwendet werden. Es kommt in diesem Zusammenhang wesentlich darauf an, einen möglichst großen schlauchförmigen Behälter 11 im Inneren eines Containers 10 unterzubringen, wobei die geradlinigen Klemmverbindungsteile nicht größer sein dürfen als die Querabmessung der Türöffnungen eines Containers.Instead of the profile of the clamping jaws shown in FIGS. 4 and 5, any other labyrinth-like sealing options can be used. In this context, it is essential to accommodate the largest possible tubular container 11 in the interior of a container 10, the straight-line clamping connection parts not being allowed to be larger than the transverse dimension of the door openings of a container.
