Definitions

  • This disclosure relates to systems for dispensing liquids from bags, in particular to a liquid dispensing system wherein liquid is dispensed from a bag via a puncturing device utilizing a single spike having a plurality of channels.
  • Conventional domestic liquid dispensers used primarily for providing heated or cooled water are usually free standing devices which dispense sterilized or mineral water from large rigid water bottles.
  • the rigid water bottles have a large body portion and a narrow neck portion having a mouth opening, and are coupled to a water dispenser by inverting the bottle and positioning the mouth of the bottle in a chamber of the water dispenser. Air, introduced into the water bottle through the mouth, allows water to be dispensed from the inverted bottle until the water level in the chamber reaches the mouth of the bottle.
  • the water bottles used with such water dispensers are fabricated from a thick, rigid, plastic material that can hold a vacuum without collapsing.
  • Such bottles are expensive and due to their cost, are usually resterilized and reused after an initial use. Because the bottles are rigid and enclosed, they are not collapsible or stackable, and require a great deal of space to transport, driving up the cost of shipping the empty water bottle back to the supplier for sterilization and reuse. These costs are adsorbed by the consumer through increased water costs.
  • the water bottles in order for the mouth of the water bottle to be positioned in the chamber of the cooler, the water bottles must have a neck, as described above.
  • the presence of the neck increases the difficulty in sterilizing the water bottles, since the neck may limit the ability of the sterilizing agents to reach all the interior parts of the bottle, even when large quantities of sterilizing agents are used.
  • heat sterilization could overcome this problem to some extent, it is generally not possible to use heat sterilization on plastic bottles.
  • ultraviolet light sterilization may lead to incomplete sterilization. Particularly troublesome, once the bottle is inverted into the fluid dispenser, the outside of the neck of the bottle can contact the fluid, and it is very difficult to maintain this area of the bottle sterile.
  • the device described therein uses a vent to permit and control flow between the bag and the chamber.
  • the vent runs parallel to the cooler's vertical axis, into which water flows when water is dispensed until the water level in the vent is level with the water level in the cooler.
  • Such a vent straw equalizes the pressure within the bag with the ambient pressure.

  • a method for dispensing liquid from a collapsible bag containing liquid comprising the steps of: providing a bag support capable of supporting a collapsible bag containing liquid during dispensing of liquid from the bag and having a supporting surface defining a first space adjacent to a first side of the supporting surface and defining a second space on a second side of the supporting surface opposite the first side, the second space being an enclosed chamber; providing a single spike comprising a puncturing tip and a plurality of noncontiguous internal channels, each channel of the plurality of noncontiguous internal channels having a plurality of apertures on the exterior surface of the spike allowing fluid to flow through the each channel, the single spike connected to the enclosed chamber such that the puncturing tip can puncture a collapsible bag containing liquid supported by the bag support, and a first aperture of the plurality of apertures of the each channel is in the second space; supporting a collapsible bag containing liquid with the

  • the liquid inlet (1 1 1) is generally closer to the rigid gasket (122) than the top opening (109) for the airflow chamber (105) so that, among other things, more water (125) in the bag (123) can flow into the chamber (135). That is, once the water level (149) in the bag (123) is below the liquid inlet (1 1 1), there will be no liquid (125) in the bag (123) capable of entering the fluid flow chamber (107) because the waterline (149) in the bag (123) is below the opening (1 1 1).

  • the pressure in the chamber (135) is reduced from the value at equilibrium (no flow), thus allowing liquid (125) to again begin to flow from the bag (123) into the chamber (135).
  • the liquid level (151) in the chamber (135) continues to decrease as the liquid (137) continues to be dispensed. So long as the volume rate of flow out of the dispensing valve (143) (i.e., out of the chamber (135)) is greater than the combined volume rate of flow into the chamber (135) through the dispensation channel (107), the pressure in the chamber (135) will also continue to decrease.
