Abstract
A wine dispenser is disclosed that protects unpoured wine from oxidation due to exposure to air within the dispenser. The dispenser includes a dispenser body having a weighted piston disposed within, the weighted piston being configured to move toward the dispensing end of the dispenser body when the dispenser is tilted downward, causing wine to be dispensed via a dispensing assembly. The dispensing assembly includes a lid having a wine flow channel that provides a path for wine to flow out of the dispenser body, and a unidirectional flow valve that is biased in a closed air-tight state to prevent air from entering the dispenser body via the wine flow channel, unless the unidirectional flow valve is forced into an open state, thereby allowing wine to flow out from the dispenser body via the wine flow channel, and then out of the dispenser via a pouring neck.
