  • Patent number: 8935977
    Abstract: A device that includes a beverage unit for delivering a beverage under pressure, at least one nozzle in fluid communication with the beverage unit to generate a jet of beverage, a receiving unit with a chamber with at least one drain opening for delivering the beverage and a jet impact member within the chamber and having a top that lies free from an inner wall of the chamber. The nozzle and the jet impact member are oriented such that the jet hits against a portion of the top of the jet impact member to form a mist of the beverage that subsequently leaves the drain opening as a beverage with a foam layer. The device is constructed such that air can only be supplied to the chamber through the at least one drain opening and/or through an air supply channel which extends through the jet impact member into the chamber.
