Definitions

  • the present invention generally relates to a bag for the transport and storage of bulk goods.
  • FIG. 1A One example of a known bag is shown in Figure 1A .
  • This known bag generally designated by reference numeral 10, comprises at least a bottom part 5 and four sides 1 to 4 connected in pairs along adjacent edges to form vertical ridges at four corners of the bag 10.
  • the bag 10 may further be provided with a lid closing the upper part thereof and provided with an aperture or spout to transfer goods inside the storage area of the bag 10.
  • the bag 10 of Figure 1A further comprises four lifting straps 6 provided in an upper portion of the bag 10 along the vertical ridges of the bag 10, which lifting straps 6 allow lifting of the bag 10 by means of a conventional four-point lifting device, such as a crane equipped with a four-point anchoring system.
  • FIG. 1B-1D Another known bag 10' is shown in Figures 1B-1D , in which the lifting straps 6 of Figure 1A are replaced by lifting straps 8 that are interconnected in pairs by two sleeves 7 to form tubings or ducts on two opposite sides 2, 4 of the bag 10' to allow lifting thereof by means of a forklift 50, as schematically depicted in Figure 1D .
  • the two sleeves 7 are particularly advantageous in that they favour and facilitate insertion and guiding of the fork arms 51 of the forklift 50 through the lifting straps 8, which lifting straps 8 are designed as structural elements supporting the bag's load.
  • FIG. 1E Another known bag 10" is shown in Figure 1E , which bag 10" combines the lifting abilities of bag 10 of Figure 1A and bag 10' of Figures 1B-1D , namely by providing additional lifting straps 9 on an upper end of the bag 10", next to the lifting straps 8 that form an integral part of the sleeves 7. Thanks to this arrangement, the bag 10" can either be lifted by means of a conventional four-point lifting device, using the additional lifting straps 9 as anchor points, or by means of a forklift, using the lifting straps 8, as already illustrated in Figure 1D .
  • a variant of the bag 10" shown in Figure 1E may consist in arranging the additional lifting straps so as to form closed loops around the lifting straps 8, like two links of a chain.
  • a problem with the known bags resides in that these bags are either solely capable of being lifted by means of one particular type of lifting device (i.e. either a four-point lifting device or a forklift) or require the provision of two separate sets of lifting straps in order to allow lifting by means of both types of lifting devices.
  • one particular type of lifting device i.e. either a four-point lifting device or a forklift
  • two separate sets of lifting straps in order to allow lifting by means of both types of lifting devices.
  • a general aim of the invention is to provide such a bag that is capable of being lifted both by means of a forklift and by means of a four-point lifting device, while keeping the bag configuration as simple as possible.
  • a further aim of the invention is to provide such a bag that is less expensive to manufacture than the known bags that are equipped with two sets of lifting straps.
  • a bag for the transport and storage of bulk goods comprising at least a bottom part and four sides connected in pairs along adjacent edges to form vertical ridges at four corners of the bag.
  • the bag further comprises four lifting straps provided in an upper portion of the bag along the vertical ridges of the bag, which lifting straps are interconnected in pairs by two sleeves to form tubings or ducts on two opposite sides of the bag to allow lifting of the bag by means of a forklift.
  • slits are provided on an upper side of each sleeve, at both ends of each sleeve, next to the lifting straps, thus forming four anchor points around the lifting straps to allow lifting of the bag by means of a four-point lifting device.
  • the slits are substantially linear slits extending parallel to the lifting straps.
  • the slits are preferably distant from the lifting straps by a distance not exceeding a couple of centimetres, in particular of the order of 1 centimetre.
  • a length of the slits likewise does not exceed 10 centimetres.
  • rounded openings may be provided at both ends of the slits, which rounded openings are advantageous in preventing or at least greatly limiting fraying of the fibrous woven material that is typically used as material for manufacturing the bags of the invention.
  • the slits are positioned on the upper side of each sleeve so as to be distant from the relevant side onto which the sleeve is formed by a distance of the order of 10 centimetres or more. This ensures adequate positioning of the anchor points with respect to the upper portion of the bag.
  • a longitudinal fold may advantageously be provided on the upper side of each sleeve, which longitudinal fold extends longitudinally along each sleeve between the slits to form a concavity along the upper side of each sleeve.
  • the sleeves may advantageously be an integral part of the opposite sides and be formed by bending each opposite side on itself to form the tubings or ducts.
  • a sewing or welding line extending along a longitudinal length of the sleeves may further be provided, at the base of the tubings or ducts, to secure an end of the opposite side on itself.
  • the lifting straps are preferably disposed on an outer side of the sleeves.
  • the sleeves may further be provided with structural reinforcements, which structural reinforcement can in particular be distributed along a longitudinal length of the sleeves.
  • FIG 2 is a perspective view of a bag in accordance with a preferred embodiment of the invention, which bag is generally identified by reference numeral 100.
  • Figure 2 shows the bag 100 in an almost fully deployed configuration as held by two persons for the purpose of illustration. It is to be understood that, in the fully deployed configuration, the bag 100 typically exhibits a generally cubic or cuboid shape, with possibly different width, length and height dimensions, depending on the relevant application and goods to be transported and stored.
  • the bag dimensions (be it the width, length or height) may in particular range from approximately 60 to more than 200 centimetres, which dimensions shall however be understood as being mentioned for the purpose of illustration only.
  • Bag 100 is preferably manufactured from woven fabric using e.g. synthetic fibre materials (such as polypropylene or polyethylene materials), which fabric is cut into pieces that are sewn and/or welded together to form the bag structure.
  • synthetic fibre materials such as polypropylene or polyethylene materials
  • Bag 100 generally shares a configuration similar to the known bag 10' of Figures 1B to 1D .
  • bag 100 comprises at least a bottom part 15 and four sides 11 to 14 connected in pairs along adjacent edges to form vertical ridges at four corners of the bag 100.
  • Bag 100 may optionally be provided with a lid closing the upper part thereof and provided with an aperture or spout to transfer goods inside the storage area of the bag 100, like the known bag 10' of Figure 1B .
  • Bag 100 likewise comprises four lifting straps 18 provided in an upper portion of the bag 100, on sides 12 and 14, along the vertical ridges of the bag 100, which lifting straps 18 are interconnected in pairs by two sleeves 17 to form tubings or ducts on the two opposite sides 12, 14 of the bag 100 to allow lifting of the bag 100 by means of a forklift.
  • the sleeves 17 are an integral part of the opposite sides 12, 14 of the bag 100 and are formed by bending each opposite side 12, 14 on itself to form the tubings or ducts.
  • it may further be contemplated to provide a sewing or welding line extending along a longitudinal length of the sleeves 17, at the base of the tubings or ducts, to secure the bended end of the opposite side 12, 14 on itself.
  • slits 20 are provided on an upper side of each sleeve 17, at both ends of each sleeve 17, next to the lifting straps 18.
  • These slits 20 are designed to form four anchor points around the lifting straps 18 to allow lifting of the bag 100 by means of a typical four-point lifting device. Thanks to the invention, it shall therefore be understood that a single set of four lifting straps, namely lifting straps 18, is used both for lifting by means of a forklift and by means of a four-point lifting device, thereby doing away with the need to provide separate sets of lifting straps as known in the art.
  • the slits 20 are designed as substantially linear slits extending parallel to the lifting straps 18. Furthermore, the slits 20 may advantageously be positioned on the upper side of each sleeve 17 so as to be distant from the relevant side 12, respectively 14, onto which the sleeve 17 is formed by a distance d (see Figure 3 ) of the order of 10 centimetres or more.
  • the distance D (see Figure 4 ) separating the slits 20 from the lifting straps 18 is likewise preferably selected to not exceed a couple of centimetres. In accordance with this preferred embodiment, the distance D is preferably of the order of 1 centimetre.
  • the slits 20 exhibit a length L (see Figure 4 ) that does not exceed 10 centimetres, which length L is sufficient to permit formation of adequate anchor points and does not compromise the function of the sleeves 17 for the purpose of facilitating lifting by means of a forklift. While slits 20 of larger dimensions could possibly be contemplated in the context of the invention, the dimensions of the slits 20 should not however be too important as the slits 20 could otherwise interfere with the introduction and guidance of the forklift arms through the lifting straps 18 and sleeves 17.
  • Tests carried out by the Applicant have furthermore demonstrated that it is particularly advantageous to further shape the slits 20 so as to exhibit rounded openings 20A at both ends of the slits 20 as highlighted in Figure 4 especially.
  • These rounded openings 20A are advantageous in preventing or at least greatly limiting fraying of the fibrous woven material that is typically used as material for manufacturing the bags of the invention.
  • each sleeve 17 it may be useful to additionally provide a longitudinal fold 25 on the upper side of each sleeve 17, which longitudinal fold 25 extends longitudinally along each sleeve 17 between the slits 20 to form a concavity along the upper side of each sleeve 17, as depicted in Figures 3 to 5 and further visible on Figure 2 .
  • the provision of this longitudinal fold 25 favours opening of the slits 20 and therefore formation and use of the anchor points around the lifting straps 18.
  • the sleeves 17 could further be provided with structural reinforcements, especially structural reinforcements that are distributed along a longitudinal length of the sleeves 17.
