A wine dispensing device for dispensing individual portions of wine from a bottle while protecting the remaining wine in the bottle against contact with the ambient air. The device uses a source of a special inert gas/carbon dioxide gas mixture connected to a delivery assembly coupled to a bottle of wine through the bottle\s cork for dispensing the contents and supply the blanketing gas mixture to the exclusion of undesired ambient air. The delivery assembly is so designed that is purged of ambient air prior to and during dispensing of the contents of the bottle.

A wine dispensing device coupled to a bottle of wine through the bottle\s cork for dispensing the contents and supplying a desired gas from an attached gas source to the exclusion of undesired ambient air, comprising: A. a base mounting sleeve having a generally cylindrical shape, comprising: a hollow lower portion which fits over a wine bottle neck; a hollow upper portion; an internal radial flange at the junction of said lower and upper portions; and a hollow cylindrical tube extending downward from said radial flange, having an inner wall whose diameter is approximately equal to the inner diameter of said radial flange, and having a lower section whose exterior portion is threaded; in combination with: B. a delivery assembly, comprising: a hollow screw assembly concentrically positioned within said base mounting sleeve, comprising: an elongated liquid tube concentrically positioned within said base mounting sleeve cylindrical tube and having an inner wall and upper and lower ends; an elongated gas tube longitudinally positioned within said liquid tube and having upper and lower ends; and a tip structure terminating the hollow screw assembly and having three sections, the top section of which is concentrically positioned within said base mounting sleeve cylindrical tube and has an outer diameter less than the inner diameter of said cylindrical tube inner wall, a midsection positioned concentrically just within said cylindrical tube and having an outer diameter slightly less than the inner diameter of said cylindrical tube and greater than the outer diameter of said top section and thereby forming a radial cavity between said tip structure top section and said inner wall of said cylindrical tube into which cavity said liquid and gas tube lower ends terminate and open, and a bottom section extending beneath said cylindrical tube tapering downward to a point and whose exterior whose exterior a “T”shaped dual channel element contained within said base mounting sleeve upper portion having a main channel into which said hollow screw assembly terminates, and two branch channels splitting off from said main channel, into one of which said liquid tube joins and into the other one of which said gas tube joins; a spring positioned around that portion of the hollow screw assembly contained within said upper portion of said base mounting sleeve and having a top end and a bottom end, the top end of which abuts said channel element and the top end of which rests on said base mounting sleeve internal radial flange; a gas feed element interconnecting said gas branch channel to said attached gas source; and a pourer connected to said liquid branch channel.
