Definitions

  • This invention relates to flexible intermediate bulk container bags such as those used in the storage and transport of materials in granular, powder or other particulate forms and known as "IBC's".
  • Such containers are generally in the form of large bags or sacks which are often required to carry loads of half a tonne, one tonne or more, with a considerable safety margin above their rated working load.
  • the containers are commonly made from woven fabric, particularly woven polyethylene or polypropylene, or of another synthetic material.
  • a container comprises a base, a main body structure of front rear and side walls extending upwardly from the base and one or more lifting loops formed from upward extensions of the side walls.
  • a waterproof liner usually formed from plastics material sheeting, for example polyethylene sheeting.
  • the invention seeks to provide a method of securing a liner to an IBC improved in the above respects.
  • a method of securing a liner within an IBC which, in its broadest form, comprises taking one or more portions of the liner separated from the content receiving portion and attaching the or each area at or near the top of the IBC.
  • the attachment may be carried out by any suitable method for example gluing, heat sealing, stitching, tying ultra-sonic welding or, preferably, by means of plastic tags applied with a tag gun.
  • a common form of liner configuration is the so called “bottle” liner.
  • This comprises a generally rectangular sheet of plastics material heat sealed or otherwise joined to form a flat rectangular "pillow” having one of its narrower sides open. Again by heat sealing or other suitable means, the width of this open side is constricted to leave a narrower opening such that when the liner is filled it resembles a bottle in shape.
  • the portions of the liner on either side of the bottle “neck” are separated from the main body by a heat seal and may be cut off.
  • these supernumerary flaps of material or "ears" are used to secure the liner to the IBC. Being separated from the main body of the liner by a heat seal, any damage to the ears during fixing to the bag does not disturb the integrity of the main body portion which will therefore remain unpunctured and waterproof.
  • IBC's to which the method of the invention may be applied are not limited to any particular kind. Indeed any conventional IBC requiring a liner may be provided with one according to the method of the invention.
  • a liner generally designated 10 is formed from a length of tubular plastics sheet material, e.g. tubular polyethylene, which is laid flat and sealed at 12 to provide a generally pillow shaped object open at its right hand edge as viewed in figure 1. Further heat seals 14 are applied so as to define a filling neck area 16 leaving the flaps 18 or "ears" separated from the main body 20 by the heat seals 14. Slits 22 are cut to partially separate the ears 18 from the filling neck 16. As illustrated in figure 1, the bag is folded longitudinally into a W shape (figure 1(b)) and the ears 18 turned down on themselves as shown in figure 1(d). The liner bottom is also folded over on itself.
  • tubular plastics sheet material e.g. tubular polyethylene
  • the liner is inserted into an IBC 24 (figure 4) having a main body portion 26, a lifting loop 28, and a filling opening 30.
  • the neck 16 of the liner is brought out of the filling opening 30 as illustrated.
  • the ears 18 are attached to one surface of the bag body by any suitable means, but preferably by tagging using a plastic tag and tag gun.
  • the bag and liner will not become separated. Furthermore, when the filled bag is discharged (often by cutting open the base of the IBC) the liner will not fall out into the discharge hopper. However, if it is desired to separate the liner from the used bag (for example for recycling) then this is easily done as it is attached only by plastic tags which can be simply cut off.
  • Figure 3 illustrates another embodiment in which the liner 10 is folded in a "omega" shape which results in the ears 18 both being on top of the folded liner rather than one on top and one underneath as with the figure 1 and 2 embodiments.
  • This is advantageous in certain instances since it means that both of the ears can be affixed to the bag 24 from the same side so that if, for instance, the bag is laid flat on the table or other work surface it does not need to be turned over to attach the second ear 18.
  • a liner 10 has a corner aperture or neck 16 and a diagonal seal 32 leaving a single "ear" 34.
  • the liner is inserted into the IBC 24 and secured at one side only by three or four plastic tags 36.
  • the ear 34 is separated from the liner main body 20 by a seal 32 so that any damage done to the ear in the tags will not affect the integrity of the liner contents.
  • the liner is attached to the bag utilising a portion 18 which is separated from the main body 20 e.g. by a heat seal line, so that any damage resulting in attachment of the portion 18 does not affect the integrity of the main body 20.
  • the liner is easily attached to the completed IBC and does not need to be attached during manufacture thereof. This enables liners to be attached to ready made IBC's to meet user specifications at short notice, or indeed liners to be changed if user specifications change.
