Definitions

  • the present invention relates to flexible containers comprising at least one lifting loop, a central part and a bottom which can consist of one or several layers of flexible material, and which possibly can be equipped with emptying means or a tapping spout.
  • the container can be equipped with an inner liner of impervious material, e.g. of polyethylene or a similar material.
  • the invention also comprises a method for manufacture of the flexible container, comprising manufacture of the container itself which has at least one lifting loop and a bottom, which can be an integral part of the container itself.
  • the invention also comprises application of the container.
  • Such flexible containers which are also called intermediate bulk containers, have found increasing application for transport and storage of several types of material, both free-flowing and lump-formed material.
  • the containers have also been used for transporting small size bags.
  • the flexible container When the flexible container is filled with free-flowing or lump-formed material, it is closed and made ready for further transport.
  • the lifting loops are placed on a hook, a lifting arm or a fork connected to some transport means. Quite often it might be practical to transport the containers to an intermediate storage. There the containers will be stacked upon each other so that the height of the storage will be equal to the height of several containers. The containers will remain at this storage for some time before they are transported to the customer. Accordingly, it might be necessary to lift and transport the container several times before it is emptied. Usually the container will, also during the discharge operation itself, be lifted so that it can be emptied through its bottom, either through a discharge spout or a hole made in the container. Because of all these lifting and transport operations between filling and discharge of the container, it is important that the lifting loops are strong and have a design which makes it possible to apply conventional means like cranes, lifting arms or fork trucks etc.
  • closed containers which can be transported by trucks, railroad, boats or aeroplane.
  • closed containers are chosen in order to reduce the risk of loss by theft or damage of the packaging. Since the transport of flexible containers in closed containers has become more important, have new demands for effective loading and unloading of the containers been stated. It has then been found that it is rather complicated to transport flexible containers in and out of the closed container.
  • the container's lifting loops which are quite practical for other purposes, turn out to be impractical for fast transport of the flexible container in and out of the closed container. The lifting height will usually be too high and it is difficult to convey a container into a deep closed container. Stacking in such closed containers is almost impossible, and when a container shall be unloaded it can be difficult to hook the lifting loop on to the lifting means.
  • the main object of the present invention was to arrive at a type of flexible containers which could easily be loaded and unloaded - in and out of closed containers, preferably by using conventional lifting and transporting means. Another object was to construct and produce such containers without amending too much on the basic construction, so that positive properties of proven flexible contaiers could be attained.
  • battens or spacing blocks could be arranged in the bottom of the container. These devices would make it possible for fork-formed lifting devices to grip or get support.
  • the battens or spacing blocks could be fastened permanently to the container's bottom or they could form part of a unit which could be fastened to the container and detached from it according to requirement.
  • the battens could be hollow or compact with different cross-sections, preferably circular or rectangular.
  • the grip bracket indicates that a fork pinnacle is in engagement with the battens or spacing blocks when these are hollow and the pinnacle is placed in the hollow space.
  • the battens could also be glued to the container's bottom or be connected to a plate which was fastened to the container's bottom by straps, or by melt gluing. This operation should preferably be carried out at the site where the container was filled with material.
  • the battens could be of any suitable material like plastic, cardboard, wood or metal.
  • plastic pipes or plastic profiles are usually the most suitable materials.
  • plastic will be the most suitable material, but wood and cardboard can be applied as well.
  • Fig. 1 a flexible container 1 with lifting loops 10 and a bottom 2.
  • battens 3 which can be placed in pockets 7 that are fastened to the bottom 2 by sewing or in other ways.
  • Fig. 2 shows a plate 4 to which are fastened hollow or compact battens 3.
  • the plate 4 can be equipped with openings 5 through which the container's discharge spout is conducted.
  • the opening 5 also makes it possible to cut a hole in the bottom 2 of the container 1 in order to empty it.
  • the batten 3 in the middle of the figure might be cut away right under the opening 5.
  • the plate 4 is fastened to the bottom 2, preferably with some kind of gluing. This operation can be carried out just before or after the container has been filled.
  • the plate 4 can also be fastened to the bottom 2 by means of straps, and these can be conducted through the container 1 just above the bottom 2 before the container is filled.
  • the container and the batten can thereby be transported separately, and a method of making the container itself is attained regardless of whether it is equipped with the batten unit or not.
  • a method of making the container itself is attained regardless of whether it is equipped with the batten unit or not.
  • the plate 4 should be connected to the container, will depend on several factors and have to be chosen in each case.
  • Fig. 3 shows a flexible container 1 with pockets 7 fastened to the bottom 2 by seams 6.
  • the battens 3 are placed in the hollow spaces 8.
  • Such a container can of course be used without battens if that is desired. If the battens 3 are placed in the pockets 7 on the filling station, will the empty, folded container from a transportation point of view not have a larger volume than a container without pockets.
  • the number of pockets 7 can be varied, but should be at least one. If only one pocket is used, it has to be wide so that the batten in it supports both forks.
  • the pockets 7 can also be fastened to the upper side of the bottom 2, but then they have to go all the way through.
  • Fig. 4 shows a flexible container having a double bottom comprising two bottom loops 2, 2', and between these are placed two battens 3, with hollow spaces 8, and can be a plastic pipe or the like.
  • the battens 3 are placed in between the bottom loops 2, 2' at the outer edges of the container's bottom just before it is filled with material. Said material will press the bottom loop 2' against the battens 3 and form loops 7. The weight of the material will keep the battens in desired position.
  • Fig. 5 shows a flexible container 1 where the pockets 7 are fastened at the outer edges of the bottom 2.
  • Fig. 6 shows a plate 4 to which is fastened several spacing blocks 11 which can be hollow or compact.
  • the blocks 11 are placed such that they form at least two rows which can give grip brackets or support for lifting forks.
  • the plate 4 can also be equipped with an opening 5 which makes it possible to empty the container.
  • the plate 4 can be fastened to the container as described in connection with Fig. 2.
  • the lifting forks are placed in the hollow spaces or between the battens themselves or the rows of spacing blocks during the lifting process.
  • the present invention has produced a flexible container which has the advantages of known containers, but it does not have their greatest disadvantages, i.e the large lifting height attained when only conventional lifting loops are used.
  • the problem of loading and unloading flexible containers in and out of closed containers has by this new container found a simple and rational solution.
  • the container according to the invention can be produced at almost the same price and with substantially the same equipment as known containers. This is especially the case when it is made with pockets sewn on to it. Placement of the battens in the pockets can be carried out where the container is filled, and there is no need for special equipment for this.
  • the container according to the invention can be made by fastening these to a conventional flexible container. Also this part of the manufacture can be carried out at the site where the container is filled with material.
