<p>A dispensing apparatus for attaching to the bottleneck of a bottle filled with a carbonated drink. The apparatus (10) includes an adapter ring (18) with angled surfaces (30) for sealing onto the bottleneck and a valve housing attached to the adapter ring (18). The valve housing having a valve closure member (46) that diverges away from sloping walls (45) of an entry chamber to provide a range of control for flow control, and soft contours at every junction to minimize turbulence. This device provides a reliable seal and an easy flow control, this one being determined by how hard the plunger button (60) is depressed.</p> |
