Definitions

  • This invention relates to flexible containers for liquids particularly of the "bag in box” type.
  • the present invention provides a flexible container in which the inner lining of the flexible container is at least partially treated to provide an embossed or perforated surface.
  • this construction enables the liquid contents of the flexible container to be pumped out without the evacuation of the container preventing egress of the liquid contents through the outlet.
  • Any pattern of perforations or embossing, which provides a network of interconnecting voids is suitable. This enables the liquid contents to flow through this network of voids to the outlet when the pump is operated to apply a vacuum or suction effect.
  • the perforations or embossing may vary in size to suit liquids with no solid content or to suit liquid/particulate suspensions such as orange juice, tomato juice etc. It will be clear that some testing will be required to match suitable embossing or perforation to different liquid/suspensions.
  • the size of perforations may range from a fraction of a micron as found in fabric material such as a spun bonded polyethylene fibre fabric, to as large as 2mm. Effective spacing of perforations is usually less than 5mm. Larger holes will tend to weaken the web if they are placed close enough to be effective.
  • Embossing is characterised by the raised section of the surface being of the order of 1-2 microns to 500 microns, spaced the same order of magnitude apart.
  • the limiting factor is that embossing will promote trapped air in the empty bag and in some applications this is required to be kept at a very low level e.g. less than 50 cc.
  • laminated wall materials materials such as, Poly 10 um- vacuum metallised polyester 12mic - Poly 50mic or 12um Polyester - 9 um Foil - 50um Poly are suitable laminants. It is undesirable to laminate a perforated liner because the perforation will be filled in. It is possible however to laminate an embossed layer or alternatively to emboss the laminant itself.
  • figure 1 is a schematic section view of a full container and figure 2 is a sectional view of a partially empty container.
  • the container as shown in figures 1 and 2 comprise a flexible container 7 disposed in a rigid support box 6.
  • the flexible container 7 is formed from synthetic plastic film which may be a laminate or two layers of film sealed together at the seams.
  • the internal film layer or liner is in accordance with this invention perforated by perforations 8. Alternatively the internal layer could be embossed.
  • the outlet 9 of the flexible container 7 is fitted into the top of the support box 6 and connected via conduit 10 to a dispensing pump.
  • the dispenser When the dispenser is activated and the liquid contents of the container 7 are drawn out the container 7 collapses under atmospheric pressure as shown in figure 2. Without presence of the perforated inner liner the collapsed container walls would restrict egress of the liquid contents of the container.
  • a 20 litre flexible bag of Coca Cola concentrate was pumped out using a "sureflo" diaphragm pump. The time taken and the remaining liquid in the bag was noted.
  • the perforated bag provides a more efficient system in evacuating the bag than conventional flow guides without the need of additional insertions into the container.
