Definitions

  • the present invention relates to improvements in and relating to bag assemblies.
  • bag for the purposes of this specification is intended to include any type of flexible or semi-flexible container and is particularly, but not exclusively directed towards large size or “bulk” plastic bags, which are becoming increasingly popular for the transportation of bulk material, such as milk powder.
  • the present invention is directed to overcoming or at least obviating or ameliorating the aforementioned problem.
  • a method of operating a bag assembly to avoid contamination of the contents of a bag forming part of the assembly including:
  • the method as above defined includes the removal of the cover means prior to an inversion of the bag and the provision of a sling to lift the bag in its inverted position during discharge.
  • the method as defined in the second paragraph immediately above includes the cover means being secured to the bag and being inverted with the bag as material is discharged during or after inversion.
  • a method of transporting material in, and discharging material from, a bag (as herein defined) is substantially as herein described with reference to any one of the embodiments of the accompanying drawings.
  • a bag assembly includes a cover means adapted in use to be positioned about a bag (as herein defined), the cover means being adapted to cover over an inlet/discharge means provided for one end of the bag and cover over at least said one end of the bag, the cover means being adapted to be removable wholly or in part to expose the inlet/discharge means when discharge of the material is required.
  • the bag assembly is adapted to be inverted when discharge of material is required.
  • FIG. 1 shows very diagrammatically a bag which may be utilised in one possible embodiment of the invention.
  • FIG. 2 shows a cover for a bag assembly according to one possible embodiment of the invention.
  • FIG. 3 shows a bag assembly according to one possible embodiment of the invention.
  • FIG. 7 shows one embodiment of the present invention with a sling being positioned over the bag assembly.
  • FIG. 8 shows diagrammatically the inversion of the bag of FIG. 7.
  • FIG. 10 shows an alternative embodiment of the invention as the bag is inverted and discharged.
  • the present invention relates to a method of packaging, transportation and discharge relating to bag of any suitable type but particularly bulk bags for powder and granular material.
  • the present invention is directed toward overcoming or at least obviating or ameliorating problems with such bulk bags to the present time, in particular, in reducing the risk of contamination of the powder or granular product.
  • one embodiment of the present invention provides an outer cover which can be removed. This removal may be achieved by merely cutting away the outer cover sufficiently to install a sling over the feed spout of the bag, the bag then being inverted and the cover fully removed.
  • the sling may be attached to eyelets which could be provided for the bag to be lifted during the discharge of the material.
  • the cover and the bag may be joined together, preferably by being made as individual components and then attached together.
  • the combined package may then be inverted for the discharge of the material.
  • the inversion will provide or promote the discharging operation.
  • vacuum may be applied to the bag to suck the contents out in providing or at least promoting the discharge of the contents.
  • the bag and the cover may be made from any suitable materials and by any suitable techniques.
  • the cover may suitably, however, be of a plastics material such as polyethylene.
  • the bag 1 may, for example, be of a size to contain 750 kg of powder or granular material and may include an inner reinforcing structure 2 to maintain the bag 1 in a substantially square shape when filled.
  • the bag 1 may also be provided with eyelets 3 and a lower tail of material 4 for a purpose which will become clearer later.
  • the bag 1 may also include a post evacuation device 5 and is shown with a spout 6 at its upper end.
  • the device 5 is suitably a valve system which may be utilised to remove gas entrapped in the bag 1 after sealing.
  • the flexible or semi-flexible bag 1 may be of any suitable material, preferably plastics.
  • a cover referenced generally by arrow 20 suitably has an open end 21 and an open upper end 22 which can fit about the spout 6 of the bag 1 .
  • the cover 20 is shown of a size substantially commensurate with that of the bag 1 so as to substantially envelope it. It is seen that there is only one spout 6 provided for the bag 1 which acts both as the inlet for the product as the bag 1 is filled and the discharge outlet when the bag 1 is emptied. In this way, avoiding the use of separate inlet and outlet spouts the risk of contamination of the bag contents is further reduced.
  • the assembled bag assembly 30 is shown with the cover 20 in position about the bag 1 .
  • the bag 1 and the cover 20 are welded together about their respective bottom ends 21 , 4 .
  • the bottom ends 21 , 4 may be left separate.
  • the assembly 30 is shown in position having the granular or powder material filling the bag 1 through the spout 6 seen particularly in FIG. 4( b ), in a direction indicated by arrow A.
  • the reinforcing structure ( 2 ), (see FIG. 1) is maintaining the bag assembly 30 in a substantially square shape.
  • FIG. 5 shows possible slip sheets.
  • FIG. 6( a ) shows a slip sheet 10 which may be of a recycled plastics which is secured to the base of the assembly 30 such as by adhesive.
  • the exposed bottom face 11 of the slip sheet 10 may suitably be relatively rough so as to provide appropriate frictional characteristics.
  • the sheet 10 is shown with upturned edges 10 a to extend upwardly of the base of the assembly 30 , to provide a suitable means for a push/pull unit to attach.
  • slip sheet 12 of FIG. 6( b ) this may include channels 13 which will facilitate the handling of the assembly 30 with a standard forklift or a push/pull forklift.
  • the slip sheet 12 may have an end downwardly depending flap 12 a again for a push/pull unit to attach.
  • Both the slip sheets 10 and 12 may be manufactured from a plastics material such as a suitable recycled plastics.
  • slip sheets 10 , 12 may be attached during bag assembly or at the time of filling.
  • FIG. 7 of the accompanying drawings a portion 14 of the cover 20 has been cut away to expose the clean inner bag 1 and allowing the installation of a sling 15 over the bag assembly 30 .
  • the bag can be inverted as indicated by arrow B.
  • the outer cover 20 can be fully removed exposing the eyelets 3 and enabling the sling 15 to be attached to the eyelets.
  • the bag 2 may then be lifted using the sling 15 and the spout 6 can be cut open in FIG. 9( c ) to allow the material to discharge as indicated by arrow C.
  • the bottom 21 of the cover 20 has been secured with the bottom 4 of the bag 1 .
  • the assembly 30 is installed on a suitable inversion means for it to be inverted as indicated by arrow D and the material emptied through the spout 6 as indicated by arrow E.
  • the act of inversion of the assembly 30 in this embodiment will provide the discharging operation, although it is envisaged that in an alternative embodiment, the discharge could be commenced once the assembly 30 is at or substantially at its fully inverted position. Depending on when discharge is to take place, the opening of the spout 6 will be appropriately attended to.
