Abstract: A tap having a body, a horizontal inlet, and primary and secondary downwardly-extending spouts, the tap having primary and secondary flow paths. The primary flow path is adapted to dispense a bulk portion of beverage and includes a horizontally oriented primary valve having a primary valve stem and a primary valve seal. The secondary flow path is adapted to dispense a foamed portion of beverage and comprises a flow restriction for inducing turbulence in a beverage flowing through the secondary flow path to produce foam, the secondary flow path including a horizontally-oriented secondary valve with a secondary valve stem and a secondary valve seal. The primary and secondary valves operate independently and have valve stems sliding on spaced apart axes.

Abstract: An apparatus for dispensing a beverage into a receptacle is provided having one or more taps, between them defining two beverage flow paths. One of the beverage flow paths is provided with a flow restriction for inducing turbulence in the beverage flow for producing foam. An arrangement is provided for directing the beverage flow path subjected to the turbulence inducing flow restriction to be not vertically orientated at an outlet such that fobbing of the beverage in the receptacle is prevented.

Abstract: Method and apparatus is described for removing oxygen from a can and frothy head inducing capsule of a lightweight two piece can beverage pack storing alcoholic beverage under gaseous pressure. The method involves evacuating the can and the capsule combination and purging with an inert gas such as Nitrogen and retaining the purged condition of the capsule and of the can by filling the can with water. Just before the can is to be filled the can is inverted to pour the water away and is washed in a conventional manner and re-inverted ready for filling. The method may be automated by marshalling cans on a conveyor and purging a large number of cans simultaneously in a batch first of all to the evacuation, then the purging step and then the water filling step. Two batch purging units may be provided and operated out of synchronism to provide a continuous supply of purged cans partly filled with water ready for feeding to the can washing and filling facility.

Abstract: A method and apparatus for the generation of a foaming dispersion of bubbles in a carbonated beverage or other gas-containing liquid packaged in a can (120) or other sealed container. An initially liquid-free device (9) having an internal chamber with an inlet/outlet valve (130/150) assembly is placed in the can, which is then filled with the beverage. The can is sealed and pasteurized, which raises the internal pressure in the can to force some of the gasified beverage into the device through the inlet valve. The outlet valve holds the quantity of beverage in the internal chamber until the can is opened, whereupon the depressurization of the can opens the outlet valve to discharge the internal chamber through an orifice to initiate seed bubbles which form a head on the beverage. The method and apparatus are particularly applicable to producing a head on fermented alcoholic beverages to simulate draught beverages.
