Definitions

  • DISPENSING APPARATUS TECHNICAL FIELD is directed to a dispensing apparatus and in particular to a dispensing apparatus to dispense liquids stored within collapsible containers such as collapsible bags or bladders.
  • beverages are supplied either in individually sized containers such as cans or bottles or in bulk form such as drums or flexible bags.
  • Flexible bags usually accommodate between 4 to 20 litres of beverage liquid.
  • suitable means are required to transfer the liquid from the bulk container to the consumer.
  • One well known method for effecting such transfer is to pressurise the bulk container so as to force the liquid through an outlet.
  • This technique is popular in dispensing beer from beer kegs.
  • a hollow rod or "spear” is inserted through an opening of an unpressurised beer keg.
  • the "spear” contains a gas inlet valve and a hollow tube.
  • the beer keg is subsequently pressurised by carbon dioxide flowing through the gas inlet valve and into the interior of the beer keg and by this action the beer is dispensed through the hollow tube. This procedure also partially carbonates the beer.
  • a disadvantage with this known procedure is that it is unsuitable for dispensing liquids or beverages which are not normally carbonated or which are sensitive to gas. Some liquids such as wines are sensitive to oxygen or carbon dioxide and can deteriorate in quality upon contact with such gases. Furthermore, many liquids such as still wines are not required to be made effervescent by absorbtion of carbon dioxide.
  • a second type of dispensing apparatus involves the use of pressure to transfer a liquid from a storage container such as a drum or collapsible bag and wherein the pressurant is not in direct contact with the liquid.
  • One type of such device comprises a rigid pressure tight container having a plunger or other type of slidable portion within the container.
  • the container is filled with the desired liquid to be dispensed and upon such filling the plunger or slidable portion is moved down towards the end of the container.
  • the portion of the container behind the plunger is pressurised thereby moving the plunger towards the outlet which in turn forces the liquid through an outlet.
  • a disadvantage with such a system is the requirement for a pressure tight seal between the plunger and the container. Such a seal is susceptible to deterioration which results in leakage or gas contamination of the liquid.
  • a second type of dispensing apparatus comprises the use of a collapsible bag located within a pressure tight container.
  • the dispensing outlet of the collapsible bag is in a pressure tight sealing relationship with the wall of the container.
  • the bag is filled with the desired liquid to be dispensed, and the pressure tight container is subsequently pressurised which in turn compresses the collapsible bag to expel the liquid.
  • the invention resides in a dispensing apparatus for dispensing a liquid from within a collapsible bag, said apparatus comprising a body portion for receiving at least part of the collapsible bag, and an inflatable bladder at least partially disposed between the collapsible bag and said body portion, whereby upon inflation of said inflatable bladder, the bladder expands against the collapsible bag to dispense liquid therefrom.
  • the invention resides in a method for dispensing fluid from a collapsible bag comprising locating the collapsible bag at least partially within the body portion of a dispensing apparatus as described above, supplying pressurised fluid to the inflatable bladder thereby expanding said bladder against a wall of the collapsible bag and continuing to inflate the bladder to cause liquid within the collapsible bag to be dispensed.
  • collapsible bag includes bladders and other flexible containers which are filled with a fluid and which upon dispensing of the fluid adopts a collapsed position.
  • the collapsible bags typically have a wall formed of a flexible inextensible metallic foil. The foil is normally coated on an inside face with a polymer to prevent tainting of the liquid by the metallic foil.
  • the collapsible bag includes a dispensing outlet.
  • the body portion may comprise an open ended substantially hollow container.
  • the container may comprise a base wall and a continuous side wall to define an interior volume with one end of the body portion being open.
  • the body portion may be of any suitable cross- sectional shape such as circular, oblong or polygonal, and can be of various sizes to accommodate various shapes and sizes of collapsible bags.
  • the body portion may be formed from paper, plastics, glass, wood, metals or a combination of these materials.
  • the body portion may comprise a sheet material or a mesh material. If desired, the body portion can be insulated to maintain the contents within the collapsible bag at a particular temperature. It is preferred that the body portion is formed from a durable material to provide a long working life.
  • the inflatable bladder may comprise a bag.
  • the bag may include an upper and lower wall joined by a seam.
  • the walls may be hemispherical.
  • One of the hemispherically shaped walls may be positioned adjacent the side wall and base wall of the body portion.
  • the other of the hemispherically shaped walls may overly a portion of the collapsible bag when placed in the body portion and may support the collapsible bag within the body portion.
  • the inflatable bladder may be of any suitable shape or size and may comprise a single inflatable member or a plurality of inflatable members which may be in fluid communication with each other or via a separate supply conduit.
  • the inflatable bag may be formed from flexible inextensible or extensible material and suitably comprises plastics, rubber, metallic foil or a combination thereof. If required, the inflatable bag can be reinforced.
  • the dispensing apparatus may include a closure to overly the open end of the body portion.
  • the closure may comprise a lid.
  • a skirt portion may depend from adjacent the periphery of the lid.
  • the lid When the closure is fitted to the body portion, the lid may substantially overly the open end of the body portion and the skirt portion may overly an upper part of the side wall of the body portion.
  • the lid may include an opening to accommodate the dispensing outlet of the collapsible bag.
  • the closure may be removably secured to the body portion.
  • the closure may be removably secured by the use of releasable fasteners.
  • the releasable fasteners may comprise a male portion located on the closure or the body portion and which releasably engages a female portion located on the body portion or the closure.
  • the male portion may comprise a hook and a female portion may comprise an eye.
  • the hooks may be spaced about the periphery of the closure or the side wall of the body portion and the corresponding eyes may be spaced about the side wall or the closure the arrangement being such that a hook can engage an eye upon positioning of the closure to the body portion.
  • the hooks are preferably pivotally mounted to be rotated into the corresponding eyes.
