Definitions

  • the invention relates to a method of temporarily increasing the vertical resistance to compression of a bag for conveying and handling liquid or quasi-liquid substances. It also relates to a bag obtained by the method.
  • a flexible container of this kind is known in particular from document WO 2009/010928 A2, which basically discloses an external envelope made up of sections of cloth, assembled and forming a roughly cubic bag containing a second envelope or liner for filling with a liquid or quasi-liquid substance.
  • the four sides of the outer envelope are made of backed cloth and divided into compartments for receiving reinforcing plates.
  • the four vertical edges of the bag forming the outer envelope are separated from the liner by strips of cloth sewn vertically and parallel to the said edges in order to counteract the tendency of the bag when filled to bulge outwardly under the pressure of the liquid it contains.
  • a special feature of trade in liquid or quasi-liquid substances, particularly concentrated fruit juice, is that the quantity of liquid actually conveyed in a container rarely depends on the maximum internal volume thereof.
  • the container is not filled up to the brim but in dependence on the order, or the volume of liquid available in the vat for emptying. For this reason, containers (flexible or otherwise) in transmit are usually filled only partly, not to full capacity.
  • Rigid containers have disadvantages as mentioned, but they have one advantage over flexible containers, in that even when partly filled they can be superposed by stacking two or three on one another.
  • the aim of the invention is temporarily to increase the resistance to vertical compression of a bag for conveying and handling liquid or quasi-liquid substances so that the bags can be stacked, thus eliminating the need to use cases for this sole purpose.
  • the process for temporarily increasing the resistance to vertical compression of a bag for conveying and handling liquids and quasi-liquids is characterised in that inflatable wedging cushions are chosen for each bag, the cushions being elongated and having a length, width and spread related to the length, width and internal volume of the bag receptacles, and in that the wedging cushions are inserted into the receptacles in order subsequently to inflate the cushions and thus confine them in a vertical position enabling them to resist compression along their vertical axes.
  • Another aim of the invention is to provide a bag by the method, a special feature of which is that the receptacles at the corners of the bag are each provided with an internal wedging cushion secured to the bag if required.
  • the bag is substantially cubic and has receptacles at each corner.
  • the bag can have four receptacles, one at each corner of the bag.
  • four wedging cushions are chosen for each bag.
  • At least one wedging bag is inserted per receptacle.
  • the wedging cushions each comprise two welded-together films, e.g. of polythene, and an inflating and deflating valve.
  • FIG. 1 is a partly exploded perspective view illustrating use of the method according to the invention.
  • FIG. 1 shows a bag for conveying and handling liquid or quasi-liquid substances constructed as taught in document WO 2009/010928.
  • a bag 1 has four sides made of backed cloth. Each side of the bag has three sections bounded by two vertical seams, in which a reinforcing panel 2 can be seen, inserted between the two pieces of cloth for each of the three sections.
  • the four corners of the bag comprise receptacles 3 forming triangular-section parallelpipeds, and the upper mouths of the four receptacles are free, not closed.
  • the spaces constituted by the four receptacles can be filled with any components needed for stacking the bags. Note that each bag interior, its central part, is occupied by a liner for filling with the liquid for conveyance.
  • inflatable wedging cushions for stabilising loads, e.g. inside large 40-foot ISO containers.
  • These cushions when deflated, look like empty flat pillowcases.
  • the cushions are made from two polyethylene films welded together over their entire periphery and comprise an inflating and deflating valve. When inflated with compressed air, the cushions look like large, particularly plumped-up pillows.
  • the cushions are used for laterally filling the space between two loads so as to keep them apart along a horizontal axis determined by the centres of the two sides of the cushion.
  • the chosen wedging cushion 4 has dimensions corresponding to the height and width of the receptacles 3 .
  • the cushion is also chosen in dependence on the position of the inflating valve 5 , which should be near a longitudinal end of the cushion.
  • each bag Four cushions are used for each bag and each is inserted, when deflated, into one of the resists 3 .
  • the four fastening cushions are inflated with compressed air.
  • Inflation inside the resists 3 has a double effect. Firstly the pressure applied to the inner faces of the receptacles increases the tension on the cloth and helps to lock the reinforcing panels 2 in position. This first effect has an immediately beneficial result, i.e. that optimum rigidity of the entire bag structure is guaranteed even if the liner is only partly filled with liquid. However this interaction between the bag structure and the cushions has a second effect, i.e. of confining each cushion in the only position permitted by the bag structure or the orientation of the receptacles 3 , i.e. an overall vertical position. Wedged in its corset, each cushion can offer high resistance to vertical forces, which could not have been foreseen.
  • the inflatable cushions can be secured, permanently or otherwise, in the bag resists and kept there during inflation and deflation, e.g. by a carrying strap or a holding lug which prevents the bag when deflated from coming out of its resistance.
  • the advantages of the method according to the invention are, firstly, a benefit during the journey from the filling place to the destination, and secondly during the return journey.
  • the filled bags can be stacked on one another and of course other loads can be placed on one or more filled bags.
  • the deflated bag has a relatively insignificant volume and practically zero weight as stated.
