Definitions

  • This invention relates to a storage bag which is particularly suitable for transportation in a container.
  • the bag of the invention will mainly find application in the storage of liquids, but is not limited to such application.
  • a bulkhead / pallet is provided with the bulkhead disposed adjacent to and supported by the doors of the container, such bulkhead / pallet serving to prevent the bag from bulging out of the container during filling and discharge operations. It will be appreciated that such a bulkhead / pallet arrangement adds weight to a load, and is also space consuming particularly in relation to an empty storage bag.
  • DE-A-3 123 150 discloses a rectangular storage container formed from a tube of flexible material by stitching a seam diametrically across the tube, flattening the seam onto material in the tube so that opposed ear formations project upwardly, and folding these ear formations flat onto the seam. One ear formation is folded back on itself to provide a spout.
  • FR-A-2 351 855 discloses a harness to support a non-rigid container against movement, comprising a number of spaced flexible steps, and anchoring straps to hold the harness in fixed relation to a support means.
  • the storage bag and the method of forming said bag are defined by the features of the independent claims.
  • the storage bag is made of flexible sheet material. It is of generally rectangular configuration, comprising a generally planar base section, opposed generally vertically disposed side wall sections, opposed generally vertically disposed end wall sections, and a generally planar roof section.
  • the term "generally vertically wall section” herein is meant to include an upwardly directed slanting wall section.
  • the bag will comprise a tubular section defining the base side walls and roof, with rectangular end wall sections being secured to each end of the tubular section.
  • the end wall sections will be constituted by two sections which fold towards one another from the side wall sections or alternatively from the roof and base sections.
  • the end wall sections will be constituted by two half sections of substantially equal size.
  • the end wall sections will be constituent by unequal sections.
  • the bag may further include a reinforcing harness comprising a plurality of strap elements whereof the free ends are adapted to be secured to the container, preferably to the floor thereof.
  • the reinforcing harness will include two or more longitudinal straps extending over the end sections and the roof of the bag, and one or more transverse straps extending over the side wall sections and the roof of the bag.
  • two longitudinal straps will be provided, the straps diverging outwardly at the end panels towards the lower bottom corners of the bag.
  • a series of cross-brace straps will preferably be provided to link the outwardly diverging straps together at intervals at one or both end zones thereof.
  • a blank of elastomeric or plastic sheet material which may or may not be reinforced with fabric for forming the bag of the invention, as disclosed herein.
  • a liquid storage bag in accordance with the invention is characterised in that it is of generally rectangular configuration comprising a base panel 10, a pair of opposed side panels 11 and 12, a pair of opposed end panels 13 and 14 and a roof panel 15.
  • the bag will be formed from a blank 16 which is of rectangular shape. By means of a longitudinal joint 29 this blank is formed into a tubular configuration. Square cutouts 31 are made in the tube to form a pair of tongues 17 at each end as illustrated in Figure 5. The tongues 17 are joined by seams 30 to make the end panel 13 as shown in Figure 6.
  • a bag formed as above and depicted in Figure 8 will be of a generally rectangular profile and particularly suitable for housing within a rigid container 19 such as a conventional ISO container. It is envisaged that the bag will be dimensioned to be a snug fit within the container 19.
  • the bag shown in Figure 8 will preferably be provided with a harness as described in more detail below and housed within the container 19,
  • An alternative arrangement is shown in Figures 9 to 12 which show a version of the bag having side and end walls which slope upwardly in a convergent fashion and which is designed to be free standing within a container 19 without the need for a harness or other supporting devices.
  • the bag is of generally trapezoidal profile.
  • the bag is formed in a similar manner to the bag shown in Figure 8, by utilizing a blank of rectangular shape, not shown, which is formed into a tubular configuration by means of a longitudinal joint 29a, Figure 10. The difference in construction is found in the cutouts 31a which were not square, but of angled shape as shown in Figure 11.
  • tongues 17a are of unequal size.
  • the tongues 17a are joined by a seam 30a and the ends folded in the manner shown in Figure 12 to provide angled end seams 18a.
  • the seams 18a will be sealed in a conventional manner with additional reinforcement where necessary.
  • the bag of Figure 9 is substantially self supporting and when housed within a container will not impinge on the container wall. Accordingly the bag will usually not require constraining means such as a harness or the like.
  • the harness Figure 3 may be provided for the embodiment of the bag shown in Figures 1, 2 and 8 to control movement thereof, during filling, discharge and transportation. Loops 24 will secure the harness to the bag, Figure 2.
  • the harness comprises a pair of longitudinal strap elements 20 and a plurality of transverse strap elements 21.
  • the longitudinal strap elements extend from the lower corner zones of the container along one end panel 14 of the bag over the upper surface 15 thereof, and along the other end panel 13 of the bag.
  • a suitable hook, clasp of the like formations 22 will be provided for securing the ends of the strap elements to eye formations 26 or the like provided on the floor of the container 19 and adjacent to the walls.
  • the longitudinal strap elements 20 are reinforced at least at the door side of the container by means of a plurality of spaced transverse linking straps 23 provided in the zone of the end panel of the bag. It has been found that the longitudinal straps 20 together with these linking straps 23 will limit excessive surge movement of the end preventing the bag from exerting undue stress on or even bulging out of the door of the container.
  • linking straps 23 define the contour of the end portions of the strap elements 20. Ring elements serve to link the various strap elements together as shown in Figure 2.
  • the transverse straps 21 of the harness extend transversely across the roof 15 of the bag and down each side panel 11 and 12 thereof as illustrated.
  • the invention relates to a novel storage bag, a blank for forming such a bag, a harness for use with the bag as well as a transportation system comprising the bag with or without the harness of the invention in combination with a rigid container.
