Definitions

  • This invention concerns the use of containers for transport and storage of dangerous goods. It particularly it concerns the use of what are known to those skilled in the art as bulk bags or Flexible Intermediate Bulk Containers (FIBCs), which are flexible bags made from woven fabrics, to transport and store dangerous powdered, granular, particulate, pelletised or briquetted solid materials.
  • FIBCs Flexible Intermediate Bulk Containers
  • FIBCs are commonly made from heavy woven textile fabrics, typically made from polyolefins such as polypropylene and polyethylene. This fabric is sometimes coated on one or both sides with a melted extrusion of similar material.
  • FIBCs sometimes include an inner liner made from polyethylene or polypropylene film to provide a barrier against moisture and/or gases and this liner may be closed by heat sealing to provide a fully sealed package for the enclosed material.
  • a normal FIBC has only a single skin of woven textile. It is usually fitted with a fill spout and often a discharge spout which are tied closed by rope or other means. Designs may vary according to the rated capacity of the FIBC and whether it is for a single use only or is reusable.
  • FIBCs are sometimes used for the carriage of dangerous materials in situations where Group 2 or Group 3 containers are mandated and the appropriate authorities must certify the package accordingly for transportation.
  • a substantially higher level of performance is required for Group 1 containers and to date an acceptable FIBC has not been put into general use for such dangerous goods and these goods have been transported only in rigid containers.
  • Group 1 dangerous goods is sodium cyanide.
  • This is widely used as a reagent in mineral processing, particularly for gold extraction, and large quantities are transported long distances from manufacturing plants to mine sites. It is commonly supplied in the form of small briquettes. Normal current practice is for such sodium cyanide briquettes to be transported in a rigid composite Intermediate Bulk Container (IBC) which comprises an FIBC inner primary package and a wooden box outer secondary package. The whole IBC package has a rated safe working load of lOOOKg.
  • the FIBC textile fabric has a coating on the inside, and a polythene liner in the box encapsulates the FIBC and is closed by heat sealing.
  • IBC's are placed in an ISO shipping container, with 20 boxes per container and transported to mine sites and the like. At the mine site, operators separate the bag from the box before lifting the bag over a discharge spike attached to a hopper.
  • the whole IBC comprising box, liner and FIBC is typically used once only and a common practice has been for the emptied IBC's to be incinerated at the sites. This practice is now restricted in many cases by changes in industry practice and/or government regulations in most countries and such regulations are becoming more stringent and more widespread. Thus such IBC's are now returned in most cases to the supplier for disposal. However such return is an expensive exercise as the total package weight is typically about 75Kg, of which the box is 70Kg with the FIBC and liner weighing 5 Kg.
  • An object of the present invention is to alleviate the disadvantages of the prior art by reducing safety hazards and reducing the amount of packaging in order to reduce the environmental impact and the cost of packaging disposal.
  • a major object is to eliminate the need for the box component while still providing an FIBC which can withstand the rigours encountered in transporting and storage with the required degree of safety required for such a hazardous bulk material.
  • the invention provides a container for transport and storage of bulk solids material said container having four sides, a top and a bottom all defining a generally cuboid shape having side edges between adjacent said sides, said container further comprising an outer casing containing an inner bag and reinforcing panel means, wherein said outer casing comprises:

  • the side walls of the further inner bag having two layers of woven fabric with said panel means inserted between those layers.
  • An opposed pair of side walls may each contain a single panel and that pair may be removable to allow the container to be folded flat.
  • an opposed pair of side walls each contain a single panel having a central vertically aligned hinge means which allows said hinged panels to fold in half whereby the container may be folded flat.
  • the two layers of outer casing fabric may be sewn to form an outwardly projecting rib which protrudes beyond the plane of each adjacent side wall at that edge.
  • the outer casing may contain a removable inner casing including said inner bag, and said outer casing may comprise:
  • said inner casing comprising:
  • - side wall covers comprising a layer of fabric covering each inner side wall and sewn to the remainder of the inner casing along the side edges, and said panel means of hard sheet material may be inserted between the two layers at each side wall between the jacket and the jacket liner.
  • the inner casing may have an internal flexible panel extending between each pair of adjacent side walls to act in tension as a gusset to restrain the side walls from bulging outwards.

Alternatively a plywood, MDF timber sheet or thick cardboard sheet may be used, but recycled plastics are preferred materials.
  • the bottom face 18 and top face 19 have no such hard panel inserts.
  • Two opposing panels 34 as shown in Figure 3, have a central vertically aligned fold crease 38 formed into the panel. This acts as a hinge to enable the panels 34 to be folded in half thus allowing the empty container to collapse flat.
  • the other two opposing panels 35 are plain unhinged panels.
  • two half-size panels could be used in an edge-abutted relationship in which the half-size panels may be not affixed to each other or alternatively may be hinged to each other by a different material, such as a fabric tape.

  • Discharge is achieved by lifting the FIBC off its pallet and over a hopper.

  • a row of stitching indicated in Figure 4 by the strand 58 passes through the inside and outside layers 12 and 13 of fabric and through the web 54 inserted between them in order to produce an outwardly projecting rib 60 which protrudes beyond the planes 64 and 65 (indicated by dashed lines) of the adjacent side walls at that edge.
  • the prominently projecting rib 60 provides substantial protection to the outside casing 11 at the side edge seam 21 where the casing would be otherwise very susceptible to damage as it does not have the protection of immediately underlying portions of the hard panels 24 to 27. It will be appreciated that the corners 22 of an FIBC constructed in this way are extremely strong due to the overlapping of multiple layers.
  • Figure 5 illustrates a structure for the side edge seams 21 which is a preferred alternative to that described above with reference to Figure 4.
  • the inside layer 12 of casing fabric is the layer formed from the seamless tube of fabric in order to provide high hoop strength.

Abstract

Grand récipient souple pour vrac (FIBC) (10), pour le transport et le stockage de matières solides en vrac. Ledit FIBC est de forme généralement cuboïde et se compose d'une enveloppe extérieure (11), d'un sac intérieur (116) et d'un moyen formant panneau de renfort (94). L'enveloppe extérieure est en tissu délimitant des surface extérieures (14-19), et comprend une ouverture obturable dans sa face supérieure, permettant le chargement des solides en vrac, et un moyen de levage (33) fixé à chaque paroi latérale (14-17) ou bord latéral. Le sac intérieur comprend au moins une couche de matériau en feuille souple, imperméable auxdites matières solides en vrac, sur ses quatre parois latérales et sur sa face inférieure. Le moyen formant panneau (94) est en matériau en feuille dur inséré au niveau de chaque paroi latérale, entre les surfaces extérieures et le sac intérieur. Ledit FIBC est utile pour les matières solides dangereuses, lesquelles peuvent se présenter sous forme de poudre, de granules, de particules, de pastilles ou de briquettes, et est particulièrement utile pour le transport et le stockage de briquettes ou pastilles de cyanure de sodium.
