Definitions

  • This invention relates to a flexible bulk bag having longitudinal recesses at the outer parts of its bottom for fitting to the forks of a fork lift so that a protruding portion of the bottom is formed between the recesses.
  • WO 92/21572 discloses a container for bulk material, which container comprises a box or bag with an insert of flexible material.
  • the box or bag can be a standard box or bag and the insert directs the bulk material in a desired mode as it is being filled in the container for the prevention of the box or bag to bulge out under the influence of the bulk material.
  • the box or bag has no longitudinal recesses at the outer parts of its bottom for the forks of a fork lift and not does the insert deal with the problems in connection with the provision of a flexible bulk bag that shall be possible to handle by means of a fork lift.
  • a bulk bag of the type defined in the preamble, however, is described in EP 665175 A1. It has external reinforcing members on the recesses. Such reinforcement must be very stiff in order to prevent the recesses from bulging out.
  • Figure 1 shows in a perspective view a bulk bag according to the invention. Interior stiffening elements are not shown.
  • Figure 2 shows in a perspective view the bottom of the bulk bag shown in Figur 1 but it does not show any stiffening elements.
  • FIGs 3-10 show in perspective views the bottom of the bulk bag as shown in Figure 2 and they also show various alternative stiffening elements in accordance with the invention. Like parts have like reference numerals in the Figures.
  • the bulk bag shown in Figure 1 is made of a flexible, thin material, for example a fabric. It comprises four side walls 11-14, a bottom 15 and a top 16 with a closable inlet 17.
  • the bulk bag has four top loops 35-38 by which it can be lifted. All parts of the bulk bag can preferably be tailored from the same material, for example the same fabric and they are fixed together, suitably by being sewn together.
  • the side walls 11,13, the bottom 15 and the top 16 can be one piece to which the other two side walls 12,14 are sewn or glued. Before the side walls are sewn together, the bottom 15 is reinforced so that it will have the form shown in Figures 1 and 2.
  • the bottom 15 will have two longitudinal and parallel recesses 21,23 and 22,24 respectively that are formed by two vertical walls 21,22 and two horizontal bottom portions 23,24.
  • the recesses 21,23 and 22,24 are adapted to be engaged by the forks of a fork lift so that the forks can lift the entire bulk bag when the bulk bag is filled with a bulk material, for example cement, corn or whatever the goods may be.
  • a bulk material for example cement, corn or whatever the goods may be.
  • the reinforcement comprises a flexible sheet 25, for example a sheet of fabric, which is sewn along the corner A-B between the walls 21,23 and the corner C-D between the walls 22,24, so that the bottom 15, the sheet 25 and the side walls 21,22 will have a rectangular cross section.
  • the sheet 25 has a number of holes 26 that permit the bulk material to pass through the sheet 25 so that it will be completely embedded in the bulk material.
  • the sheet 25 will thus be tension loaded so that it stabilizes this rectangular form when the bulk bag is filled with bulk goods.
  • the bulk bag can be lifted by the forks of a fork lift as an alternative to be lifted in its lift loops.
  • FIG. 5 shows an embodiment slightly modified from the one in Figure 4.
  • the sheets 27,28 has a common seam E-F to the bottom 15.
  • Figure 6 there are a number of individual strips 29 extending between the corner A-B and the corner C-D and sewn to the corners. Between these strips 29 there are strips 30 extending the opposite way. All these strips will also be embedded in the bulk material. From the emptying point of view, separate strips with openings between them are better than sheets with holes in them.
  • the embodiment of Figure 3 can be modified to have separate strips coupled between the corners A-B and C-D instead of the single sheet 25. Then, there can be a distance between adjacent strips to allow for the bulk material to embed the strips.
  • Figure 7 shows an embodiment in which there are a number of vertical parallel strips 31 extending between the walls 21.22 and sewn to these walls.
  • the strips 31 are sewn to the walls and they can additionally be sewn to the bottom 15.
  • Figures 8 and 9 show other arrangements of strips extending between the walls 21,22.
  • Figure 10 shows four vertical strips 32 arranged between the side walls 12,14 of the bag and the walls 21,22 and extending past the four corners of the protruding bottom portion.
  • the stiffening and stabilizing sheets or strips are arranged symmetrically and are arranged to be embedded in the bulk material when the bag is filled. They will be tension loaded by the bulk and will maintain the form of the longitudinal recesses 21,23 and 22,24.
  • the stabilizing strips or sheets can preferably be made of the same material as the entire bag. The entire bulk bag with its stabilizing strips or sheets is described as being sewn together. It can alternatively be glued together or fixed together in any other suitable way.
  • the bulk bag can be provided with a bottom spout for emptying the bag.
  • the stabilizing strips should then preferably not be fixed to the bottom 15.
  • Other modifications can also be made within the scope of the claims.
