Definitions

  • the present invention relates to beverage dispensing nozzles and, more particularly, but not by way of limitation, to a beverage dispensing nozzle for dispensing multiple flavored drinks, including flavor additives, from a single nozzle without intermingling drink flavors.
  • the flavored syrup, and, if desired, flavor additive be intimately mixed with a mixing fluid, such as carbonated or plain water, so that the resulting drink is of uniform consistency.
  • a mixing fluid such as carbonated or plain water
  • the mixing fluid is carbonated water
  • the carbonated water and syrup, and, if desired, flavor additive be mixed in such a manner that the carbon dioxide does not excessively escape and produce undesirable foaming.
  • Another problem that must be addressed is proper mixing of the mixing fluid, such as carbonated or plain water, and syrup, and, if desired, flavor additives.
  • the mixing fluid such as carbonated or plain water, and syrup
  • flavor additives To insure proper mixing, it is necessary to expose the maximum surface area of the syrup, and, if desired, flavor additive, to the mixing fluid. If the mixing is to occur outside the nozzle, it is important that the momentum of the syrup stream, and, if desired, flavor additive stream, be substantially equal to or less than the momentum of the mixing fluid stream.
  • Excessive foaming is another problem when the mixing fluid is carbonated water.
  • the carbonated water which enters the nozzle at a high pressure, must be gently reduced to atmospheric pressure so that a minimum of carbon dioxide will escape solution.
  • out-gassing of carbon dioxide is particularly troublesome. Consequently, as the carbonated water releases carbon dioxide in both the nozzle and the cup, the released carbon dioxide escaping solution causes excessive foaming of the dispensed beverage. That excessive foaming creates a poor product because the drink is generally "flat".
  • U.S. Patent 3,277,924. which issued on October 11, 1966, to Nezworski, discloses a flow regulator of a nozzle for a soft drink mixing and dispensing apparatus.
  • the flow regulator regulates the release of flavouring syrup.
  • the disclosed nozzle delivers flavouring syrup and mixing fluid through separate annular flow paths, wherein mixing occurs in the region of the nozzle exit.
  • the preamble of claim 1 is based on US 3,277, 924.
  • an object of the present invention to provide a beverage dispensing nozzle that dispenses a beverage syrup and mixing fluid at a high volume flow to form a dispensed beverage drink.
  • the beverage dispensing nozzle of the present invention may be utilized with a counter top or similar beverage dispenser.
  • a mixing fluid such as carbonated or plain water
  • a mixing fluid is delivered to the discharge end of the beverage dispensing nozzle through an annular channel.
  • the beverage dispensing nozzle discharges the mixing fluid in a circular path around its exit end.
  • a selected beverage syrup is delivered to the discharge end of the beverage dispensing nozzle through a concentric annular channel.
  • the annular channel may be partially closed at its discharge end to restrict the beverage syrup flow, thereby insuring adequate momentum to propel the beverage syrup from the beverage dispensing nozzle into intimate contact with the mixing fluid.
  • a selected flavor additive is delivered to the discharge end of the beverage dispensing nozzle through a flavor additive conduit.
  • the mixing fluid is delivered to the exit end of the nozzle through an annular channel that is concentric to the beverage syrup annular channels.
  • the mixing fluid surrounds an exiting beverage syrup stream and flavor additive stream and is directed inwardly for maximum surface contact with the beverage syrup and flavor additive.
  • the mixing fluid travels at substantially equal or higher momentum than the beverage syrup and flavor additive to insure proper mixing.
  • a second stream of mixing fluid exits through a center conduit in the beverage dispensing nozzle. This is particularly the case for large volume nozzles.
  • the most significant feature of the invention is the distribution of beverage syrup in a circumferential pattern around the exit end of the beverage dispensing nozzle, thus presenting the greatest surface area for contact with the mixing fluid.
  • the momentum of the syrup as it exits the nozzle is controlled so that it is substantially equal to or less than the momentum of the mixing fluid to insure intimate mixing, while avoiding carbon, dioxide breakout when the mixing fluid is carbonated water.
  • the beverage dispensing nozzle includes a first annulus, a second annulus, and a third annulus that form three annular beverage syrup channels along with an inner housing. Furthermore, the third or innermost annulus includes a flavor additive conduit therethrough to permit the inclusion of a flavor additive in the dispensed drink.

  • the conduits 45-47 are concentrically spaced apart so that beverage syrup may enter the chamber 40 at three separate points.
  • the interior wall of the inner housing 16 defining the chamber 40 includes stair-steps 48-51.
  • the first or outer annulus 17 includes an upper member 52 and a discharge member 53 (refer to Figs. 1 and 2).

  • the third or inner annulus 19 fits within the second or intermediate annulus 18 such that the securing member 60 protrudes through the opening 44 of the inner housing and engages the interior wall of the inner housing 16 defining the opening 44.
  • the securing member 60 may press fit with the interior wall of the inner housing 16 defining the opening 44 or, as in this first embodiment, an adhesive may be used to secure the securing member 60 with the interior wall of the inner housing 16 defining the opening 44.

  • annuluses 17-19 one of ordinary skill in the art will recognize that alternative shapes, such as elliptical or polygonal, may be utilized.
