Definitions

  • This invention relates to container bags and in particular to container bags for carrying loads in the range of one-­half to two tonnes and known as Intermediate Bulk Containers (IBC's).
  • IBC's Intermediate Bulk Containers
  • Intermediate Bulk Containers are increasingly employed in cargo handling and transporting situations, especially for the carriage of particulate and pulverulent material.
  • a typical IBC will be manufactured from a fabric woven from polyolefin tape yarn and have integral lifting loops. Examples of such containers are decribed in UK Patent Nos. 1591091 and 2063816.
  • IBC's being flexible, need to be supported during filling, for example from their lifting loops. In many applications this is no great problem since IBC's will be filled sequentially from a hopper containing fertiliser, cement, or the like. However, in other applications such as the on site removal of rubble or other waste material, the fact that an IBC is not self supporting is a considerable disadvantage.
  • the invention seeks to provide an IBC improved in the above respects.
  • a container bag which comprises a body of flexible material having lifting loops characterised in that the body is provided with stiffening to enable it to be free standing.
  • the stiffening is removable or at least demountable so that the IBC can be folded or rolled for transport and storage.
  • the stiffening comprises four ribs or rods of a suitable material such as metal, wood, plastics material and the like retained in suitable channels formed in the IBC walls.
  • stiffening material comprises stiff but resilient rods, for example of nylon.
  • the stiffening may be in a number of discrete lengths which may be linked by, for example, corner fittings so as to form a framework and thereby support the IBC in its free standing configuration.
  • the fabrics from which the IBC of the invention are formed may be conventional fabrics for use in this type of container bag and may be woven from polyethylene or polypropylene tape yarns.
  • the lifting loops are attached to such reinforced areas.
  • the IBC may be 'underslung' where the lifting loops extend down the side walls and under the base of the container body. In either case the lifting loops will preferably be of a woven webbing of synthetic yarns, for example of the type used for car seat belts and in IBC lifting loops, or may be ropes or hawsers of suitable strength.
  • the container bag of the invention may be fitted with a filling spout but, since it is primarily intended for piecemeal filling on site it is preferred that the top be left substantially open. Discharge spouts may be provided, and in a preferred form the entire base of the bag may be openable to give a rapid release of the bag's contents. This may be effected by means conventional in the IBC art.
  • an intermediate bulk container generally designated 10 comprises side walls 12, a base 14 and lifting loops 16.
  • the lifting loops 16 are of woven webbing and are attached to reinforcing bands 18 interwoven in the sides 12 of the body 10 by suitable means such as stitching, for example in a box and cross stitching pattern.
  • the side walls 12 carry vertical channels 20 and horizontal channels 22 formed by lines of stitching 24 defining pockets for stiffening rods 26.
  • the rods 26 are formed into a framework by means of removable corner fittings 28a or 28b.
  • the top of the IBC illustrated is left open for easy filling and the base 14 is closed by a releasable flap 30 attached by means of straps 32 to a suitable quick release means (not shown) on the IBC side wall.
  • the IBC can be folded flat for storage and transport and can, for example, be supplied stacked on a pallet or in bales.
  • an IBC is unfolded and four corner units 28 fitted thereby forming an orthogonal framework allowing the IBC to be self supporting and free standing.
  • the IBC may be filled piecemeal, by means of shovels, mechanical diggers, or the like possibly over a period of time. When full it may be lifted by means of the loops 16 either employing a fork lift truck or a crane in the manner known per se.
  • the quick release flap 30 ensures rapid discharge of the contents when the IBC has been transported to the discharge point. The flap 30 may then be reconnected by means of the straps 32 and the IBC returned for further use.
  • the supports are thin nylon rods which have the necessary stiffness to allow the IBC to be free standing yet are sufficiently resilient to withstand the forces involved in handling a filled IBC without themselves breaking.
  • the IBC may be reused.
  • the support rods may be of flimsier or less resilient material which may well be broken during handling or lifting of the IBC which of course is after they have performed their function of holding the IBC upright during filling.
  • the IBC of the invention is ideal for use at building and construction sites and the like.
