Abstract:
1. Liquid metering apparatus for a bottle containing a liquid comprising: a) a pourer body containing a tubular flow conduit having a flow bore, wherein the flow bore communicates with a liquid inlet port located between a dispensing port and a return port, wherein the inlet and return ports are located to mount in a bottle and the dispensing port mounts external to the bottle; b) a primary valve piece mounted in said flow bore for reciprocating motion between forward and aft valve seats respectively located upstream and downstream of said inlet port to direct liquid between said inlet port, said dispensing port and said return port; c) a metering orifice located downstream of said aft valve seat to regulate hydraulic movement of said primary valve piece in said flow bore; and d) a pressure control assembly having a control valve piece responsive to rotation of said pourer body relative to an inclined position where liquid enters the inlet port to vary a pressure condition downstream of said metering orifice such that said primary valve piece is restrained to said aft valve seat by a first pressure established at a rotation angle before said inclined position and is released when said control valve piece is manipulated to establish a second pressure equal to or greater than the first pressure at or past said inclined position to meter liquid flow through the pourer.
