Definitions
- the invention relates to a flexible container which comprises a sack made of flexible, thin-walled material, in particular fabric, and an inner lining for influencing the wall properties, in particular water and water vapor permeability.
- Transport containers in the form of sacks made of flexible, thin-walled materials are widespread and also known as flexible containers or belt containers.
- Such containers preferably consist of high-strength fabric, e.g. Polypropylene fabric, a sack-shaped container with the corresponding number of carrying loops being formed from several webs of this fabric.
- Such transport containers are typically used to hold about 500 to 2000 kg of bulk material.
- a water or water vapor-tight design of the transport container is necessary, e.g. for cement.
- Such inner bags give the necessary tightness, but are disadvantageous in handling.
- the inner sack when emptying the bulk material through the discharge nozzle, since it forms pockets that obstruct the discharge or hang down and there is a risk of getting into running devices.
- the transport container according to the invention is primarily characterized in that the lining is tight and has sewing pockets on the outside, on which it is sewn to the sack.
- the lining is preferably formed from a film tube, on the outside of which the sewing flaps are glued or welded on in the form of strips of material.
- FIG. 1 shows an oblique view of a transport container according to the invention
- Fig. 2,3 schematically show sections through two different embodiments of the inner bag
- Fig. 4 shows the arrangement of the inner bag in the outer bag of the transport container
- Fig. 5 shows broken the arrangement of sewing pockets on the inner bag
- FIG. 6 shows a preferred embodiment of a transport container.
- the sack 1 essentially consists of the sack 1 and the inner sack 3, the upper end of which is drawn out of the sack 1.
- the sack 1 consists of four fabric sheets 2 and the cover 10 and the bottom 4, these two parts also consisting of fabric sheets.
- the outlet nozzle 5 is located in the bottom and the filler neck 6 in the lid, both nozzles preferably also being made of fabric.
- belt loops 8 are arranged at the upper end of the sack in order to be able to lift the sack accordingly.
- the belt from which the loops 8 are formed is preferably sewn to the sack 1 along the entire length of the seam edge 7.
- the straps can also be guided around the bottom 4 to improve the carrying capacity of the transport container.
- Fig. 2 shows in section the preferred design of the cross section of the inner bag 3. It consists of a section of a tube with a corresponding diameter and of film, such as Low pressure polyethylene. This material is high strength with a small thickness, low weight and low cost. Sewing pockets 9 are glued or welded to the outside of the hose. The sewing pockets have a length that corresponds approximately to the length of the seam 7 of the finished transport container. For reasons of easier mechanical production, the tabs can also be guided over the entire length of the film tube forming the inner bag.
- film such as Low pressure polyethylene. This material is high strength with a small thickness, low weight and low cost.
- Sewing pockets 9 are glued or welded to the outside of the hose.
- the sewing pockets have a length that corresponds approximately to the length of the seam 7 of the finished transport container. For reasons of easier mechanical production, the tabs can also be guided over the entire length of the film tube forming the inner bag.
- Fig. 5 shows in an oblique view the formation of such a film tube.
- the hose usually comes in a folded form with side gussets wound on rolls for processing.
- the sewing pockets 9 are glued or welded along the edges.
- Fig. 4 shows schematically a cross section through the transport container Fig. 1, wherein the sewing pockets 9 of the inner bag 3 are sewn to the webs 2 along the seam 7.
- the arrangement of the sewing pockets 9 ensures that the inner bag is firmly connected to the outer bag of the transport container, the tightness of the inner bag 3 being nevertheless ensured.
- the length of the inner bag 3 is essentially such that it protrudes through both the outlet nozzle 5 and the filler neck and can be tightly tied together with them.
- Fig. 3 shows an embodiment of the inner bag, which is not glued or welded from a tubular film, but from individual film webs.
- the two mutually opposite webs 11, 11 protrude outward beyond the adhesive points with the webs 12, 12 lying between them and thus form the sewing pockets 13.
- FIG. 6 shows the design and arrangement of a preferred embodiment of the inner bag 3.
- the outer bag 1 is only partially shown, the bottom 4 with the outlet nozzle 5 and the lid 10 with the filler neck 6 being missing.
- the inner bag 3 extends upwards over the length of the outer bag 1 and thus forms an apron 14 at the upper end, which serves to fill in the bulk material and then close it.
- the inner bag 3 merges into a running outlet nozzle 15, the conical or curved narrowing shape of which favors the discharge of the bulk material.
- Both the outlet nozzle 15 and the apron 14 can be sealed together in a known manner with the closing parts of the external fabric bag - not shown here - e.g. by tying with ribbons.
- the inner bag remains firmly connected to the outer bag by sewing along the seam edges 7, even if the bulk material is emptied.
- the inner bag cannot be torn out, as is the case with conventional flexible containers of this type.
- the filling of the bulk material is also easier, since the inner sack is always fitted in the correct shape.
