A dispensing apparatus for attaching to the bottleneck of a bottle filled with a carbonated drink. The apparatus includes an adapter ring with angled surfaces for sealing onto the bottleneck and a valve housing attached to the adapter ring. The valve housing having a valve closure member that diverges away from sloping walls of an entry chamber to provide a range of control for flow control, and soft contours at every juncture to minimize turbulence.

Liquid dispensing apparatus for controllably dispensing pressurized liquid from a container, a discharge opening therefrom being located above the surface of the liquid contained within the container, comprising an adapter for matingly sealably connecting with the discharge opening of the container, said adapter including a central opening, an elongate tube insertable through said central opening of said adapter such that the lower end thereof is within the liquid, an elastomeric resilient 0-ring sealing against the outside surface of said tube near its upper end, said adapter including a shoulder for limiting the downward location of said O-ring, a dispensing valve housing seatably connectable to the top of said adapter and surrounding the top of said tube, said housing having a valve chamber contiguous with the top opening of said tube, the walls of said chamber gradually reducing in dimension to form a valve seat at the upper end of said chamber, said housing having a channel above said valve seat, an elongate valve plunger having a bulbous lower closure end operably located within said chamber and with an external surface that diverges below said valve seat from the adjacent wall of said chamber, said closure end having a contact seating surface above its maximum diameter dimension, said plunger having an elongate plunger shaft operating within said channel and connected to said bulbous lower end, said shaft being smaller in diameter than said channel, bias means connected to said plunger for urging the plunger upward to close its closure end in said valve seat, and a dispensing spout having an input opening into said channel, wherein downward pressure applied to said valve plunger overcoming said bias means causes the downward descent of said bulbous closure end into said chamber to provide an increasingly larger flow path between said walls of said chamber and said closure end for liquid drawn from the container depending on the increasingly downward position of said valve plunger.
