Fuente: WIPO "wine" A preservation and dispensing apparatus includes a pressurized gas supply assembly for pressurizing and dispensing fluid from a bottle in a manner that effectively creates a barrier protecting the fluid from harmful effects of oxygen. The pressurized gas supply assembly includes an inert gas output linked to the bottle via a dispensing nozzle secured within an opening of the bottle. The dispensing nozzle includes a connecting seal having a series of outwardly directed, flexible fins composed of a first material and an outwardly tapered seal member composed of a second material. The inert gas output includes a regulator assembly having a piercing pin that passes through an end cap of a gas capsule allowing gas from the gas capsule to pass through the regulator assembly. The regulator assembly reduces the gas pressure from approximately 2700 psi to approximately 5 psi in a single step.
