WINE DISPENSER THAT PRESERVES WINE QUALITY BY REDUCING OXIDATION OF CONTAINED WINE WHEN THE DISPENSER IS PARTIALLY FULL

摘要

A wine dispenser is disclosed that preserves wine by reducing oxidation when partially filled with wine. The dispenser includes: a bottle body having a uniform cross section; a piston disposed within the bottle body for pushing the wine therethrough; a drive member capable of pushing the piston along the bottle body; and a dispensing assembly attached to the dispensing end. The dispensing assembly includes: a shoulder having a wine flow channel, the wine being able to flow out only via the wine flow channel; a neck in sealable and rotatable relationship with the shoulder, the neck having a pouring end and a flow regulation end, the flow regulation end having at least one opening that can be rotated so as to permit wine to flow in from the wine flow channel, through the at least one opening, and out through the pouring end, when pressure is applied to the piston.
