US Patent 9745187 Carbonated fluid dispenser with ultrasonic foaming mechanism

The embodiment relates to beverage dispensing, and more particularly to the dispensing of a beverage, from a beverage container into a vessel, providing a portion of the beverage as foam atop the dispensed beverage. To avoid the reduction of absorbed carbon dioxide in a carbonated beverage, increased atmospheric pressure is employed to move the beverage from the container through the apparatus and into the vessel. An oscillating means provides a sonic wave through a conduit and the liquid therein; the sonic wave initiates the reaction between the carbon dioxide and the ingredients in a carbonated beverage to cause the liquid to foam prior to dispensing into the vessel.
