Definitions

  • 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 clamping device made of several rods that can be fixed against each other.
  • Such containers have a volume of 1000 l or 2000 l, for example, and are primarily intended for use in the event of a disaster. For example, they can be used to supply the population with drinking water. However, they are also suitable, for example, for storing drinking water or waste water on ships or for storing other liquids.
  • the containers are generally transported by truck, 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.
  • closure It is also necessary to make the closure as easy to use as possible, especially for rapid use in the event of a disaster. Finally, in some cases it may be necessary to design the closure to be as space-saving as possible, for example to enable a stacking of several containers.
  • a closure suitable for this purpose with the features mentioned at the outset is known, for example, from DE-OS 30 04 884.
  • the closure described in this laid-open document consists of clamping bodies arranged one above the other in side holders, through the separating joints of which one end of the semifinished product is passed.
  • the clamping bodies are arranged to be displaceable relative to one another and can be braced against one another with a clamping device that can be inserted into each holder.
  • a disadvantage of the known closure is given by the construction of a relatively large number of individual parts, which complicate its handling and increase the susceptibility to faults. Furthermore, the dimensions of this closure are relatively large, so that stacking of several containers on top of one another is greatly hindered. The dimensions of the closure are particularly disadvantageous for containers with a small capacity.
  • the object is therefore to provide an improved closure for flexible containers made of tubular or sack-shaped semifinished products for transporting and storing flowable or pourable goods, with a clamping device comprising a plurality of rods which can be fixed against one another.
  • the clamping device has a winding rod provided with a slot, that the upper part and the lower part of the container can be inserted into the slot and can be wrapped tightly and without creases by at least 270 ° with at least two deflections around the edges of the winding rod formed by the slot, and that the winding rod can be wound through at least one other rod is secured against winding.
  • Such a closure consists of only a few parts and is hardly susceptible to failure. In addition, it has a significantly lower weight than the known closures.
  • the length of the slotted winding rod corresponds at most to the width of the filled container and the height of the entire closure corresponds to at most the height of the filled container.
  • This embodiment has the particular advantage that several containers can be stacked one above the other, for example in wire mesh boxes, or a container can be transported in a folding box. Such a configuration is facilitated if a neck is attached to the open end of the container.
  • the further rod is formed by a rod-shaped clamping element which is connected to the winding rod by means of clamping screws.
  • the tensioning element can be designed as a rail with a U-shaped profile, which partially or completely accommodates the slotted winding rod.
  • the other rods can also be formed from two opposing rectangular tubes or profiled rods which are connected to one another by means of tensioning screws leading through the slotted winding rod outside the slot length of the winding rod.
  • the further rod is formed by a sleeve which firmly encompasses the wound container opening and can be pushed onto the winding rod and which, in the pushed-on state, is fixed non-rotatably with respect to the winding rod.
  • the further rod as a sleeve
  • a quick and reliable fixation of the container opening wound on the winding rod is achieved. Additional elements such as Tensioning screws, which can be lost when the closure is open and during cleaning of the container, are not required.
  • the sleeve can be pushed onto the winding rod in the axial direction. Since it is fixed non-rotatably in the pushed-on state, the wound-up container opening cannot come loose by itself, so that the container is closed properly at all times. The handling of the closure is even easier and the susceptibility to faults is reduced.
  • the sleeve and the winding rod are held non-rotatably due to a profile cross section of the sleeve and the winding rod that deviates from the circular shape.
  • the profile cross section of the sleeve and the profile cross section of the winding rod can be rectangular, in particular square, or oval. This special design of the profile cross-sections means that there is no need for an additional anti-rotation lock.
  • the sleeve is held non-rotatably on the winding rod by means of anti-rotation devices engaging in both parts.
  • the end of the sleeve can be provided with a notch
  • the longitudinal slot also serves as a notch, this preferably being used at both ends of the sleeve for receiving one pin each, which is arranged at the two ends of the winding rod.
  • the longitudinal slot together with the pins serves as a guide for pushing the sleeve onto the winding rod. This prevents the sleeve from twisting relative to the winding rod during the sliding on.
  • the sleeve consists of an elastic material and is in frictional connection with the outside of the wound-up container opening.
  • the height of the longitudinal slot is preferably somewhat less than the height of the flattened container opening, the longitudinal edges of the longitudinal slot of the sleeve abutting the upper and lower part of the container after being pushed open. An inadvertent shifting of the sleeve in the pushed-on state relative to the winding bar is made more difficult.
  • the opening opposite the front entry opening of the sleeve is closed by a plate.
  • This plate serves as a stop, which ensures easy positioning in the axial direction when the sleeve is pushed onto the winding rod.
  • the sleeve has a U-shaped profile cross section and can be pushed on transversely to the axial direction of the winding rod, with a locking device being arranged at the two ends of the sleeve.
  • a lock which is articulated on the sleeve and is rotatable and engages behind the winding rod, can be provided to prevent displacement.
  • a ring that can be pushed onto the end is also conceivable as a means of securing against displacement.
  • the U-shaped sleeve is used when wide container openings are closed must be, which would lead to a high frictional resistance with an axial displacement of the sleeve.
  • the edge of the container opening protruding into the slot of the winding rod is arranged within the winding rod. This avoids disturbing elevations of the wound container opening, which make it difficult, if not impossible, to slide the sleeve open.
  • the bag-shaped, flexible container 1 shown in FIGS. 1 and 2 consists of an upper part 2 and a lower part 3, which are joined together on their two longitudinal sides and on one end face to form a common edge 5, for example glued or welded to one another.
  • the upper part 2 is provided with a filling opening 4.
  • the second end face of the container 1 serves as a container opening 7, which opens into a neck 6.
  • the container opening voltage 7 is closed by a closure 8.
  • the neck 6 When the container 1 is closed, the neck 6 is passed through the winding rod 10 provided with a slot 9 in the middle and then wound tightly and without folds by rotating the winding rod 10 in the direction towards the center of the container in the embodiment shown in FIG. 3 by at least 360 ° .
  • the layers of the container opening 7 can also overlap by repeated turning.
  • the neck 6, as can be seen in FIG. 3, is deflected at several points.
  • the rotation achieved can be fixed by tightening clamping screws 13, which are suitably provided near the ends of the winding rod 10.
  • the clamping screws 13 pass through a clamping element 12 with a U-profile and through the winding rod 10 and are e.g. tightened by a mother.
  • the fixing element has the shape of two rectangular tubes 14, which are connected with clamping screws 15, which lead through the winding rod 10 outside the area of the slot 9.
  • FIG. 5 to 9 show further embodiments of the closure 8, which differ in particular by the fixing element.
  • the flattened container opening 7 of the empty container 1 is in turn inserted into the slot 9 of the winding rod 10, the edge of the container opening 7 coming to rest within the winding rod 10.
  • a sleeve 16 with a longitudinal slot 21 is pushed onto the winding rod 10 in the axial direction by firmly gripping the wound container opening 7.
  • the longitudinal slot 21 of this sleeve 16 comes with its two longitudinal edges on the upper part 2 and the lower part 3 of the container 1 to the plant.
  • both the winding rod 10 and the sleeve 16 have a rectangular profile cross section, so that both parts are non-rotatably fixed to each other. In this way, the container opening 7 is closed, the pushed-on sleeve 16 ensuring that the container opening 7 no longer detaches from the winding rod 10.
  • the profile cross sections of both the winding rod 10 and the sleeve 16 are triangular.
  • the two parts are fixed so that they cannot rotate.
  • the winding rod 10 and the sleeve 16 have a round profile cross section, so that in this embodiment an additional anti-rotation device must be provided.
  • Fig. 7b The end of the sleeve 16 is provided with a notch 20, into which, after the sleeve 16 has been pushed on, a pin 19 arranged at the corresponding end of the winding rod 10 and extending in the radial direction engages as an anti-rotation device.
  • the longitudinal slot 21 in the sleeve 16 can also serve as the notch 20. In this case, the longitudinal slot 21 also serves as a guide for pushing on the sleeve 16.
  • the sleeve 16 has a U-shaped profile cross section and is pushed on transversely to the axial direction of the winding rod 10, that is to say from the right in the drawing.
  • an additional locking device is provided in order to prevent the sleeve 16 from slipping off the container opening 7 wound on the winding rod 10.
  • a bolt 17 is rotatably arranged on the sleeve 16 in FIG. 8b, which is in the dashed position before and during the sliding of the sleeve 16 onto the winding rod 10. After being pushed on, the bolt 17 is rotated downward and thus prevents the sleeve 16 from coming loose.
  • Fig. 9a and 9b Another possibility is shown in which a clip-like ring 18 is pushed onto each of the ends of the sleeve 16.
  • the container 1 is bag-shaped so that only one closure 8 is required.
  • the volume of the container 1 can thus be reduced to a certain volume from two sides.
