초록

A cartridge containing one or more beverage ingredients and comprising an inlet for the introduction of an aqueous medium and an outlet for the beverage produced from the one or more beverage ingredients, the cartridge incorporating within a beverage flow path between the inlet and the outlet an eductor for entraining air into the beverage, the eductor comprising an aperture for producing a low pressure jet of the beverage.

1. A method of using a cartridge for the preparation of beverages, the method comprising: introducing an aqueous medium into an inlet of a cartridge;mixing the aqueous medium with one or more beverage ingredients within the cartridge to form a beverage;directing the beverage in a first direction into a channel between a pair of spaced, curved walls of the channel;passing the beverage over an air inlet opening of the channel to entrain air into the beverage, the channel comprising a floor and the air inlet positioned at the floor of the channel;impacting the beverage with entrained air against an impact surface of one of the curved walls of the channel downstream of the air inlet opening;directing the beverage with entrained air in a second direction out of the channel and into a chamber of the cartridge along a spiral-shaped wall of the chamber;imparting a spiral-shaped flow to the beverage within the chamber about an outlet opening of the chamber using the spiral-shaped wall of the chamber; anddischarging the beverage into a receptacle. 2. The method of claim 1 wherein imparting the spiral-shaped flow to the beverage includes causing the beverage to travel around the chamber about the outlet opening at least once before exiting the chamber via the outlet opening. 3. The method of claim 1 wherein directing the beverage into the chamber includes directing the beverage generally along an axis into the chamber; and imparting the spiral-shaped flow to the beverage within the chamber includes imparting an asymmetrical flow to the beverage on opposite sides of the axis. 4. The method of claim 1 wherein directing the beverage into the chamber of the cartridge includes directing the beverage along the channel from a first position above a floor of the chamber to a second position at the floor of the chamber. 5. The method of claim 4 wherein directing the beverage along the channel from the first position above the chamber floor to the second position at the chamber floor includes directing the beverage along a curved, sloped floor of the channel. 6. The method of claim 1 wherein the chamber outlet opening is disposed at a center of the chamber; passing the beverage over the air inlet opening of the channel to entrain air into the beverage includes forming air bubbles of varying sizes in the beverage including a first portion of the air bubbles and a second portion of the air bubbles; andimparting the spiral-shaped flow to the beverage within the chamber includes: conveying the first portion of the air bubbles outward toward an outer wall of the chamber; andconveying the second portion of the air bubbles inward toward the center outlet opening of the chamber and collapsing the second portion of the air bubbles. 7. The method of claim 1 wherein impacting the beverage against the impact surface includes a potential power dissipation of the beverage in the range of 0.002 Watts to 15.0 Watts. 8. The method of claim 7 wherein the potential power dissipation of the beverage is in the range of 0.1 Watts to 5.0 Watts. 9. The method of claim 8 wherein the potential power dissipation of the beverage is 0.34 Watts. 10. The method of claim 1 wherein directing the beverage into the channel includes forming a jet of the beverage and passing the beverage over the air inlet opening includes passing the jet over the air inlet opening. 11. The method of claim 10 wherein forming the jet of beverage includes passing the beverage through an aperture and discharging the jet of beverage from the aperture wherein the jet has a velocity in the range of 1.25 meters per second to 100 meters per second as the jet exits the aperture. 12. The method of claim 11 wherein the jet exiting the aperture has a velocity in the range of 6.9 meters per second to 35 meters per second. 13. The method of claim 12 wherein the jet exiting the aperture has a velocity of 17.13 meters per second. 14. The method of claim 1 further comprising passing the beverage through a filter of the cartridge. 15. The method of claim 1 wherein passing the beverage over the air inlet opening of the channel to entrain air into the beverage includes drawing air into the beverage at a flow rate in the range of 333 millimeters cubed per second to 13,333 millimeters cubed per second. 16. The method of claim 15 wherein the air flow rate is in the range of 667 millimeters cubed per second to 6,667 millimeters cubed per second. 17. The method of claim 16 wherein the air flow rate is 1,233 millimeters cubed per second. 18. The method of claim 1 further comprising directing the beverage along the one curved wall of the channel having a radius of curvature in the range of 1.50 mm to 5.50 mm. 19. The method of claim 18 wherein directing the beverage along the one curved wall of the channel includes directing the beverage along the one curved wall of the channel having a radius of curvature in the range of 2 mm to 3 mm. 20. The method of claim 19 wherein directing the beverage along the one curved wall of the channel includes directing the beverage along the one curved wall of the channel having a radius of curvature of 2.5 mm. 21. A method of using a cartridge for the preparation of beverages, the method comprising: introducing an aqueous medium into an inlet of a cartridge;mixing the aqueous medium with one or more beverage ingredients within the cartridge to form a beverage;directing the beverage in a first direction into a channel between a pair of spaced, curved walls of the channel;passing the beverage over an air inlet opening of the channel to entrain air into the beverage, the channel comprising a floor and the air inlet positioned at the floor of the channel;impacting the beverage with entrained air against an impact surface of one of the curved walls of the channel downstream of the air inlet opening;directing the beverage out of an exit opening of the channel in a second direction and into a chamber of the cartridge along a spiral-shaped wall of the chamber, the spiral-shaped wall beginning at the exit opening of the channel and extending about the chamber such that the beverage travels into the chamber along a path offset from a central axis of the chamber extending through a center of an outlet of the chamber;rotating the beverage around the central axis of the chamber;directing the rotating beverage into the outlet of the chamber; anddischarging the beverage into a receptacle. 22. The method of claim 21 wherein rotating the beverage around the central axis of the chamber includes causing the beverage to travel around the central axis of the chamber a plurality of times before exiting the chamber via the outlet. 23. The method of claim 21 wherein rotating the beverage around the central axis of the chamber includes imparting a spiral-shaped flow to the beverage within the chamber. 24. The method of claim 21 wherein directing the beverage into the chamber of the cartridge includes directing the beverage along the channel from a first position above a floor of the chamber to a second position at the floor of the chamber. 25. The method of claim 24 wherein directing the beverage along the channel from the first position above the chamber floor to the second position at the chamber floor includes directing the beverage along a curved, sloped floor of the channel. 26. The method of claim 21 wherein directing the beverage into the channel includes forming a jet of the beverage. 27. The method of claim 21 further comprising passing the beverage through a filter of the cartridge. 28. The method of claim 21 further comprising directing the beverage along the one curved wall of the channel.
