Definitions

  • 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.
  • the container is provided with a tightly closable inner container which is formed from flexible plastic material.
  • this container essentially assumes the shape of the interior of the container.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 .
  • 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.
  • 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.
  • 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.
  • a flexible container according to the invention 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.
  • 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.
  • the outline of a container 10 is shown with dash-dotted lines.
  • 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.
  • the container 11 is otherwise essentially cylindrical in shape.
  • 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.
  • FIG. 2 and 3 show the container 11 in the container 10 in the emptied state.
  • the loading and unloading device 12 is located at the top, whereas in the figure a drain pipe 15 is arranged at the bottom.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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).
  • 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.
  • plastics or elastomers come into question, these enclosing and penetrating one or more fabric layers from both sides.
  • elastomers nitrile, butyl rubber and the like
  • thermoplastics PVC, PP, PE
  • the individual webs can be welded together by high frequency.
  • any other labyrinth-like sealing options can be used.
  • 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.
