  • Output tube 62 is in fluid communication with port 61 and aeration port 65.
  • Aeration port 65 is disposed on tube 62 at a point where the aeration port is outside of the refrigerated portion of the machine when nozzle 10 is assembled within the dispensing machine.
  • exit tube 62 includes a fluid restrictor 70, shown in Fig. 9, disposed therein. Fluid restrictor 70 creates fluid pressure, thus increasing the velocity of fluid within exit tube 62.
  • the fluid in exit tube 62 having increased velocity, passes by aeration port 65 pulling air from outside of the exit tube into the stream of fluid.
  • restrictor 70 acts with aeration post 65 to provide a venturi effect. Air within the stream of fluid within exit tube 62 excites flavor and creates a foam head within the product. In a preferred embodiment, restrictor 70 sealed to within exit tube 62 via sonic welding.
  • cover 20 is adapted to be sealed to spout 40, preferably via an interference fit.

  • output tube 62 is in fluid communication with first input 21 , second input 22, mixing chamber 25 and static mixer 45.
  • nozzle 10 is placed within the refrigerated portion of the dispensing machine with first input 21 connected to the source of condensed fluid, second input 22 connected to the source of water, output tube 62 extending out of the machine and aeration port 65 on the outside of the refrigerated portion of the machine.
  • aeration port 65 is located immediately adjacent to the dispensing machine, thus eliminating un-refrigerated fluid in output tube 62.
  • aeration port 65 enables air to be pulled into the stream of fluid within exit tube 62 to excite flavor and create a foam head within the product.
  • aeration port 65 located just outside of the dispensing machine, acts to provide an air vent for fluid trapped between the machine and the end of output tube 62.
  • aeration port 65 allows all un- refrigerated fluid to exit output tube 62.
  • nozzle 10 is provided as a disposable nozzle.
  • Disposable nozzle 10 improves the cleanliness of the dispensing system without requiring time consuming clean-up.
  • disposable nozzle 10 is included as part of a kit, which includes a plurality of nozzles 10 within a box. Each nozzle 10 of the kit is individually packaged within a hermetically sealed flexible package.
