Abstract

A closure for flexible containers made of hose- or sack-shaped semi-finished products for transporting and storing of flowable or pourable goods, with several rod-shaped or tubular clamps, which are arranged one upon another in side supports and securable in their position to each other and through their separation places one end of the hose- or sack-shaped semi-finished product can be led. In order that the closure can also withstand strong jolt stresses on the filled containers, the clamps are arranged clampable with respect to one another in the supports surrounding their ends and clampable with respect to each other, having one clamping device each which can be inserted into each support.

Description

Die Erfindung betrifft einen Verschluß für flexible Behälter aus schlauch- oder sackförmigen Halbzeugen zum Transportieren und Lagern von fließ- oder schüttfähigen Gütern, mit mehreren stab- oder rohrförmigen Klemmkörpern, die in seitlichen Haltern übereinander angeordnet und gegeneinander in ihrer Lage sicherbar sind und durch deren Trennfugen ein Ende des schlauch- oder sackförmigen Halbzeuges hindurchführbar ist.The invention relates to a closure for flexible containers made of tubular or sack-shaped semifinished products for transporting and storing flowable or pourable goods, with a plurality of rod-shaped or tubular clamp bodies which are arranged one above the other in side holders and can be secured in position against one another and by their joints one end of the tubular or sack-shaped semi-finished product can be passed through.

Solche Behälter haben einen Inhalt von beispielsweise 20001 und werden vornehmlich im Katastrophenfall eingesetzt, beispielsweise zur Versorgung der Bevölkerung mit Trinkwasser. Der Transport erfolgt in der Regel mit Lastkraftwagen, deren zulässiges Gesamtgewicht nicht überschritten werden darf. Infolgedessen kann es bei Verwendung kleinerer Lastkraftwagen erforderlich werden, den Behälter nicht ganz zu füllen. In diesem Falle können aber während der Fahrt dynamische Massenkräfte der Flüssigkeit das Fahrzeug in Gefahr bringen, so daß ein Verschluß erforderlich ist, mit dem der Behälter auf das für die transportierte Flüssigkeitsmenge erforderliche Restvolumen verkleinert werden kann.Such containers have a content of, for example, 20001 and are primarily used in the event of a disaster, for example to supply the population with drinking water. Transport is usually carried out by lorries, the permissible total weight of which must not be exceeded. As a result, when using smaller trucks, it may be necessary not to fill the container completely. In this case, however, dynamic inertial forces of the liquid can endanger the vehicle while driving, so that a closure is required with which the container can be reduced to the residual volume required for the amount of liquid transported.

Ein für diesen Zweck geeigneter Verschluß mit den eingangs beschriebenen Merkmalen ist bekannt (DE-B-2 239 097). Dieser bekannte Verschluß besteht aus zwei Verschlußstäben, die als Umlenkstäbe ausgebildet sind, denen im Abstand und parallel dazu je ein weiterer, äußerer Umlenkstab zugeordnet ist. Die Umlenkstäbe sind an wenigstens einem ihrer Enden durch Steckverbindungen lösbar und an dem anderen Ende fest oder lösbar miteinander durch Halter verbunden. Das zusammengelegte Ende des Behälters wird dann durch die Lücke zwischen den beiden mittleren Umlenkstäben hindurchgeführt und zweimal in umgekehrter Richtung durch die Lücken zwischen den mittleren und ihren benachbarten Umlenkstäben zurückgeführt. Dieser bekannte Verschluß funktioniert bei ruhender Lagerung oder erschütterungsfreiem Transport schon zufriedenstellend, hat aber den Nachteil, daß er sich bei starker Stoßbeanspruchung des Behälters doch noch teilweise oder ganz öffnen kann, so daß es zu Leckverlusten kommt.A closure suitable for this purpose with the features described above is known (DE-B-2 239 097). This known closure consists of two locking rods which are designed as deflecting rods, to which a further outer deflecting rod is assigned at a distance and parallel thereto. The deflecting rods are detachable at least on one of their ends by plug-in connections and are fixedly or detachably connected to one another by holders at the other end. The collapsed end of the container is then passed through the gap between the two middle diverter bars and returned twice in the reverse direction through the gaps between the middle and its adjacent diverter bars. This known closure works satisfactorily when stored at rest or during vibration-free transport, but has the disadvantage that it can still partially or completely open when the container is subjected to heavy impact, so that leakage losses occur.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, den bekannten Verschluß so zu verbessern, daß er unter Beibehaltung einer leichten und unkomplizierten Handhabung zuverlässig geschlossen werden kann und auch starken Stoßbeanspruchungen des gefüllten Behälters standhält.Proceeding from this, the object of the invention is to improve the known closure in such a way that it can be closed reliably while maintaining easy and uncomplicated handling and can also withstand heavy impact loads on the filled container.

Diese Aufgabe wird für einen Verschluß der eingangs beschriebenen Gattung dadurch gelöst, daß die Klemmkörper gegeneinander verschiebbar in den ihre Enden umgreifenden Haltern angeordnet und mit je einer in jedem Halter einsetzbaren Klemmvorrichtung gegeneinander verspannbar sind.This object is achieved for a closure of the type described in the introduction in that the clamping bodies are arranged so as to be displaceable relative to one another in the holders encompassing their ends and can be braced against one another with a clamping device that can be used in each holder.

Bei einer praktischen Ausführungsform können die beiden Halter aus U-förmigen Profilen bestehen, zwischen deren Schenkel die Klemmkörper eingelegt sind. In weiterer Ausgestaltung der Erfindung können die beiden Halter mit einem der äußeren Klemmkörper zu einem starren U miteinander verbunden werden, so daß die übrigen Klemmkörper mit den beiden Klemmvorrichtungen gegen den fest eingebauten und als Widerlager dienenden Klemmkörper verspannbar sind.In a practical embodiment, the two holders can consist of U-shaped profiles, between the legs of which the clamping bodies are inserted. In a further embodiment of the invention, the two holders can be connected to one another in a rigid U with one of the outer clamping bodies, so that the remaining clamping bodies can be clamped with the two clamping devices against the permanently installed clamping body and serving as an abutment.

Die Klemmvorrichtung kann in einer praktischen Ausführungsform aus einem Exzenter bestehen, der mit seitlichen Zapfen in Bohrungen der Stege der beiden Halter einsetzbar ist. Zur Erleichterung der Handhabung beim Einsetzen in die Halter kann der Exzenter auf einer zweiteiligen, gegen die Wirkung einer Druckfeder axial zusammenschiebbaren Büchse angeordnet sein, deren Außen- und Innenbüchse in der zusammengeschobenen Endlage mit einem Haltestift gegeneinander fixiert werden können.In a practical embodiment, the clamping device can consist of an eccentric which can be inserted with lateral pins in bores in the webs of the two holders. To facilitate handling when inserting into the holder, the eccentric can be arranged on a two-part bush that can be axially collapsed against the action of a compression spring, the outer and inner bushes of which can be fixed against one another in the pushed-together end position with a retaining pin.

Ein erfindungsgemäß ausgebildeter Verschluß hat außer einer einfachen Handhabung den zusätzlichen Vorteil, daß die Klemmkörper nicht nur von dem um sie herum geschlungenen Ende des Behälters zusammengezogen, sondern zusätzlich durch die Klemmvorrichtungen zusammengepreßt werden. Dieser Verschluß kann sich auch bei starken Stoßbeanspruchungen nicht öffnen, wie sie beispielsweise beim Abwurf des gefüllten Behälters von der Ladepritsche eines Lastkraftwagens auftreten können.A closure designed according to the invention has, in addition to simple handling, the additional advantage that the clamping bodies are not only drawn together by the end of the container which is wrapped around them, but are also pressed together by the clamping devices. This closure cannot open even in the event of heavy impact loads, such as can occur, for example, when the filled container is dropped from the loading platform of a truck.

A preferred embodiment of a closure designed according to the invention has been shown in the accompanying drawings. In the drawings shows
  • Figure 1 shows a filled container with closure in side view.
  • Figure 2 shows the same container in plan view.
  • Fig. 3 shows the closure along the line 111-111 in Figure 2 in an enlarged view.

Als Ausführungsbeispiel ist ein sackförmiger, flexibler Behälter 10 gewählt worden, der aus einem Oberteil 11 und einem Unterteil 12 besteht, die an ihren beiden Längsseiten und an einer Stirnseite zu einem gemeinsamen Rand 13 zusammengefügt, beispielsweise miteinander verklebt oder verschweißt sind. Das Oberteil 11 ist mit einer Einfüllöffnung 14 versehen.As an exemplary embodiment, a bag-shaped, flexible container 10 has been chosen, which consists of an upper part 11 and a lower part 12, which are joined together on their two longitudinal sides and on one end side to form a common edge 13, for example glued or welded to one another. The upper part 11 is provided with a filling opening 14.

Die offene Seite des Behälters 10 ist mit einem Verschluß 15 verschlossen, der von zwei seitlichen Haltern 16 und 17 mit U-förmigem Querschnitt, fünf rohrförmigen Klemmkörpern 18a bis 18e und zwei Klemmvorrichtungen 19 gebildet wird.The open side of the container 10 is closed with a closure 15, which is formed by two lateral holders 16 and 17 with a U-shaped cross section, five tubular clamping bodies 18a to 18e and two clamping devices 19.

Die beiden Halter 16 und 17 sind mit dem äußeren Klemmkörper 18a zu einem starren U miteinander verbunden, wobei die offenen Seiten des Profiles der beiden Halter 16, 17 nach innen zeigen. Auf diese Weise können die gleichlang geschnittenen Klemmkörper 18b bis 18e in die Profile der beiden Halter 16 und 17 eingelegt werden.The two holders 16 and 17 are with the outer clamping body 18a connected to a rigid U, with the open sides of the profile of the two holders 16, 17 facing inwards. In this way, the clamping bodies 18b to 18e of equal length can be inserted into the profiles of the two holders 16 and 17.

Dabei wird zweckmäßig gleichzeitig das zusammengelegte offene Ende des Behälters 10 zwischen den Klemmkörpern 18 eingelegt, so daß es nicht nachträglich eingefädelt werden muß.The folded open end of the container 10 is expediently inserted between the clamping bodies 18 at the same time, so that it does not have to be subsequently threaded.

Am freien Ende sind die beiden Halter 16 und 17 in ihren Stegen auf gleicher Höhe mit Bohrungen 21 versehen, in welche die Klemmvorrichtungen 19 eingesetzt werden können. Jede Klemmvorrichtung 19 besitzt einen Exzenter 22, der auf einer Außenbüchse 23 angeordnet ist, einer Innenbüchse 24 und einer zwischen Außen- und Innenbüchse 23, 24 angeordneten Druckfeder 25. Außerdem besitzen die Außen-und Innenbüchsen 23, 24 an ihren Enden Zapfen 27, mit denen sie in die Bohrungen 21 der Halter 16 und 17 eingreifen.At the free end, the two holders 16 and 17 are provided in their webs at the same height with bores 21 into which the clamping devices 19 can be inserted. Each clamping device 19 has an eccentric 22 which is arranged on an outer sleeve 23, an inner sleeve 24 and a compression spring 25 arranged between outer and inner sleeve 23, 24. In addition, the outer and inner sleeves 23, 24 have pins 27 at their ends which they engage in the bores 21 of the holder 16 and 17.

Damit die Klemmvorrichtungen 19 nicht auseinanderfallen und gleichzeitig auch in ihrer zusammengeschobenen Endstellung für das Einsetzen in die Halter 16 und 17 fixiert werden können, ist die Innenbüchse 24 mit einer axialen Abflachung und einer diese anschneidenden, auslaufenden Nut 29 versehen. Mit einem quer zu der Abflachung 28 in die Außenbüchse 23 eingesetzten Haltestift 30 können dann beide Teile gegeneinander gesichert werden. Wenn die Außenbüchse 23 und die Innenbüchse 24 im zusammengeschobenen Zustand etwas gegeneinander verdreht werden, greift der Haltestift 30 in die Nut 29 ein und fixiert auf diese Weise die beiden Teile in ihrer zusammengeschobenen Endstellung. Zum Einsetzen in die Bohrungen 21 der beiden Halter 16 und 17 brauchen dann nur die beiden Teile wieder etwas gegeneinander verdreht zu werden, so daß die Druckfeder 25 die Zapfen 27 in die Bohrung 21 drücken kann.So that the clamping devices 19 do not fall apart and at the same time can also be fixed in their pushed-together end position for insertion into the holders 16 and 17, the inner sleeve 24 is provided with an axial flattening and an outgoing groove 29 that cuts it. With a holding pin 30 inserted transversely to the flattening 28 into the outer bush 23, both parts can then be secured against one another. If the outer sleeve 23 and the inner sleeve 24 are slightly rotated against one another in the pushed-together state, the retaining pin 30 engages in the groove 29 and in this way fixes the two parts in their pushed-together end position. To insert into the bores 21 of the two holders 16 and 17, only the two parts then need to be rotated slightly against one another again, so that the compression spring 25 can press the pins 27 into the bore 21.

Um die Außenbüchse 23 und die Innenbüchse 24 gegeneinander verdrehen und den Exzenter 22 spannen zu können, sind die Zapfen 27 entweder - wie dargestellt - mit Schlitzen 31 und/oder - wie aus der Fig. 5 ersichtlich - mit einem Vierkant oder Mehrkant versehen. Dem Vierkant- oder Mehrkantzapfen muß ein entsprechendes Kant-Loch zugeordnet sein.In order to be able to rotate the outer sleeve 23 and the inner sleeve 24 against one another and to tension the eccentric 22, the pins 27 are either provided with slots 31 and / or - as can be seen in FIG. 5 - with a square or polygon. A corresponding square hole must be assigned to the square or polygonal pin.

In dem dargestellten Ausführungsbeispiel ist der Behälter 10 sackförmig ausgebildet, so daß nur ein Verschluß 15 benötigt wird. Es ist aber ebensogut möglich, als Behälter 10 ein an beiden Enden offenes, schlauchförmiges Halbzeug zu verwenden, wobei dann zwei Verschlüsse 15 verwendet werden müssen. Mit dem oder den Verschlüssen 15 kann das Volumen des Behälters 10 in der gewünschten Weise verkleinert oder vergrößert werden. Dafür ist es ausreichend, die Klemmvorrichtungen 19 durch Verdrehen der Exzenter 22 zu lösen. Danach ist schon eine Verkleinerung oder Vergrößerung des Behälters möglich.In the illustrated embodiment, the container 10 is bag-shaped so that only one closure 15 is required. However, it is equally possible to use a tubular semifinished product which is open at both ends as container 10, in which case two closures 15 must then be used. With the closure or closures 15, the volume of the container 10 can be reduced or increased in the desired manner. For this it is sufficient to release the clamping devices 19 by turning the eccentric 22. After that, the container can be reduced or enlarged.
