Abstract
A pouring attachment device for a disposable package of nitrogenated beverage, e.g. an aluminium can P, that achieves a desirable foam head when the beverage is poured into a glass. The attachment comprises a main body or housing (11), an ultrasonic wave generator (27) and a means to couple the device to the package, such as a rim seal (2)0. A flow channel has a contoured inlet (26) configured for communicating beverage from the package to an outlet (21), via a resonance chamber (28), and is particularly configured for minimising turbulence.
Claims13
A pouring attachment device for a disposable container of nitrogenated beverage comprising:
- a housing;
- an ultrasonic wave generator;
- a coupling configured for coupling to a container;
- a flow channel configured for minimizing turbulence of poured beverage, the flow channel comprising:
- an inlet recess, upstream of the ultrasonic wave generator and configured for communicating beverage from the container toward an outlet, the inlet recess having a contoured wall for directing beverage flow in a manner that minimizes turbulence;
- a resonance chamber having a first cross sectional area, downstream of the inlet recess, a surface of the ultrasonic wave generator being arranged at least partially overlapping against the resonance chamber;
- a nozzle having a distal outlet end of reduced cross-sectional area compared to the first cross sectional area;
- wherein walls of the flow channel are configured to smoothly transition from the resonance chamber, without abrupt or semi-abrupt steps, toward the distal outlet end in a manner that minimizes turbulence, and wherein the nozzle comprises an upstream, elongate cross section transverse to a longitudinal axis of the nozzle, having a width greater than its height, to interface with a corresponding elongate cross section of the resonance chamber.
