Definitions

  • This invention relates to the transportation of bulk cargo within cargo containers and more particularly to inserts for such containers and methods of use thereof.
  • Bulk cargo may be loaded into cargo containers and then transported in these containers from one location to another by ship, truck, or railstock or some combination thereof. Once the containers reach their destination various techniques may be employed to unload the cargo from the container.
  • Cargo containers are generally lined with an air and/or water-flexible liner. This ensures that the cargo remains protected and uncontaminated during transportation.
  • the encapsulation of the cargo within the liner also allows the cargo to be readily moved within the container. For example, the provision of air bags enables the cargo to be centred within the container.
  • container e,g 30ft containers
  • the container is ramped up at one end, with the cargo passing through a flap which extends substantially along the width of the bottom of the container at the opposing end.
  • This flap is generally termed in the art a "letterbox" opening.
  • the liner is arranged into what is generally termed in the art as a “fish-tail” discharge. This discharge is then attached to an appropriate outlet means/collection means.
  • a problem associated with the current cargo containers is that once this letterbox is opened it becomes impossible to close it, as the weight of the cargo forces the liner to protrude out through the letterbox. This becomes a particular problem if the container is dropped on a corner. If the liner bulges out in this matter the cargo has to be fully unloaded, often in the inappropriate place. This can obviously cause substantial logistical problems with the associated financial costs.
  • liners When loading the cargo into the liner, the "fish-tail" discharge must be maintained in a closed position and furthermore prevented from moving underneath the liner, thus becoming inaccessible.
  • liners In order to address this problem liners generally incorporate a long string double rubber. However, if the side walls become trapped under this mechanism the possibility of the fishtail becoming trapped under the liner remains.
  • a further problem associated with the current cargo containers is that the documents required to travel with the cargo are placed on top of the liner. When the documents are checked, e.g at the discharge destination or ports, personnel have to climb up ladders to the top of the container open a hatch and retrieve the documents. This practice has led to particular Health and Safety concerns, particularly if the documents are retrieved in wet conditions when the lid of the container may become slippery.
  • the invention therefore provides an insert which enables the repeated opening of the letterbox, this enables any documentation to be easily and repeatedly accessed through the letterbox, and for a sampling point to be located behind the letterbox. Furthermore, this insert enables the perfect orientation of the fish-tail discharge with the letterbox.
  • an insert for use in a cargo container comprising a panel which is adapted to form, when in use, a wall member and a base, wherein the panel is provided with a frangible region to form a cargo discharge outlet.
  • the panel is provided with an axis which defines the junction between the wall member and the base and about which the wall member and the base can be angled relative to each other. Even more preferably this axis is a fold line extending along the width of the panel.
  • the wall member and base are angled at substantially 180°.
  • the wall member and base are in a substantially parallel orientation relative to one another.
  • the wall member and base are angled at substantially 0 ° relative to each other.
  • a means may be provided in order to reversibly retain this orientation.
  • Such means may, for example, be an adhesive or an article comprising an adhesive, such as double-sided tape. This embodiment may be particularly useful during the storage of the inserts.
  • the wall member and the base are in a substantially perpendicular orientation relative to one another.
  • the wall member and base are angled at substantially 90 ° relative to each other.
  • the insert can be located substantially parallel with a wall of the container liner whilst also extending under the base of the container liner. In this orientation and positioning relative to the liner, the insert addresses a number of problems associated with the prior art. Firstly, as mentioned above, if the container liner inappropriately protrudes out of an aperture of the cargo container, for example through the letterbox, it is impossible to re-close the letterbox due to the pressure exerted by the bulk cargo.
  • the provision of the insert prevents this protrusion because it is manufactured of a material that is capable of withstanding such pressures without bulging. Secondly, there is a tendency during the loading of bulk cargo for the fishtail discharge of the container liner to become trapped underneath the liner. This causes great difficulties when the bulk cargo is to be unloaded, as it is extremely difficult to free the trapped fishtail from underneath the load. The insert prevents this problem from occurring by ensuring the perfect placement of the fishtail prior to loading. The provision of the base on the insert, which is inserted underneath the base of the container liner prevents the fish-tail from being able to move underneath the liner and thus become trapped.
  • the cargo comprises a heavy and/or dense powder such as terephthalic acid (PTA)
  • PTA terephthalic acid
  • an additional piece of strengthening material is secured to at least part of the base region of the insert.
  • the material may be attached to either the upper and/or lower surfaces of the base region.
  • the material may extend substantially along the length of the base regions, or alternatively may be provided in discrete regions along the length of the base region.
  • this strengthening material is manufactured of a plastics. Even more preferably this strengthening material is a woven polypropylene.
  • the strengthening material may be secured to the base of the insert by a number of techniques known to the skilled man, including the use of adhesives.
  • the base of the insert may be secured to the underside of the liner, for example, by the use of the use of an adhesive.
  • a cargo discharge outlet of the container liner cooperates with a cargo discharge outlet on the cargo container.
  • the fishtail is positioned through letterbox and the cargo then unloaded.
  • the insert is sandwiched between the cargo container and the container liner it prevents this of co-operation between these two outlets. Due to the weight of the cargo pressing down on the insert base, it is not possible to remove the insert in an intact form prior to unloading the cargo.
  • the wall member of the insert is provided with a frangible region. The dimensions of this frangible region are such that a cargo discharge outlet of the container liner can readily pass through it. More preferable still the dimensions of this frangible region are such that the fishtail can pass through it.
  • the dimensions of the frangible region are substantially similar to the dimensions of the cargo discharge outlet of the cargo container. Even more preferably still the dimensions of the frangible region are substantially similar to the dimensions of the letterbox.
  • the frangible region When the cargo is to be unloaded, the frangible region is opened to form an aperture within the insert, thereby allow the placement of the cargo discharge outlet of the container liner through the cargo discharge outlet of the cargo container.
  • the frangible region comprises a ripcord.
  • the ripcord is secured to the insert by passing the ends of the ripcord through two apertures and securing, for example by the formation of a knot at the ends on the side of the insert which, when in use is adjacent to the container liner.
  • the frangible region comprises plurality of perforations along which the frangible region can be opened. More preferably these perforations are orientated in a substantially straight line, even more preferably still a substantially horizontal line.
  • the provision of one ripcord results in a slit-like aperture being made in the insert through which the cargo can flow.
  • the frangible region is completely removed from the insert, thereby enabling an increased flow rate of the cargo.
  • the aperture is substantially rectangular in shape and is formed by the provision of two rip-cords which are orientated substantially horizontally along the upper and lower edges of the insert and which are transected by two vertical perforation lines.
  • a knife or similar sharp instrument may be used to break the line of perforations, although this may cause damage to the container liner and thus result in the inappropriate discharge of the cargo within the cargo container itself. Therefore, preferably the frangible region is provided with a ripcord, which is secured to along the line of perforations and which when pulled, disrupts the perforations.
  • the insert is of a substantially rigid material.
  • the insert is of cardboard, even more preferably still of corrugated cardboard.
  • the dimensions of the insert should be such that they match the dimensions of the cargo discharge outlet on the cargo container.
  • the width of the insert should sufficient to fully cover the letterbox.
  • the base of the insert should also be sufficient to extend under the base of the liner without the risk of the base becoming dislodged when the cargo is loaded.
  • the insert is reversibly secured to the liner. Even more preferably this is by the provision of an adhesive, such as glue or double-sided tape.
  • the insert In order to prevent personnel having to climb on top of the cargo container to retrieve documents the insert is provided with a document retaining means, allowing the document being accessible through an aperture in a wall member of the cargo container.
  • this aperture is a flap, such as the letterbox.
  • the document retaining means is preferably in the form of a re-usable pouch or envelope which may be reversibly secured to the insert. The document can be repeatedly accessed through the letterbox with the insert preventing the container liner from protruding through the letterbox.
  • the insert is provided with a cargo sampling port.
  • this sampling port is re-sealable. Even more preferably still this port is located behind the letterbox and is capable of cooperating with a sample spout which is placed through an letterbox.
  • the cargo container comprises bulk cargo.
  • bulk cargo include, but are by no way limited to; grains (e.g corn, maize germ, maize grit, rice wheat), bulk commodities (e.g chocolate crumb, cocoa beans, coffee and sugar) and chemicals (e.g aluminium oxide, PET, polyester, PVC, polypropylene, PTA).
