Abstract
A gas dispensing device uses small liquified gas cartridges having, for example, nitrogen or carbon dioxide, in a hand-held canister unit with a thumb operated valve. In a simple form with an extension tube at its lower end, the device is useful for injecting a blanket of oxygen-devoid gas into a bottle containing a perishable liquid such as wine, so that the partially used bottle of wine can then be recorked and preserved. In this form the device can also be connected to a special closure secured to the mouth of a carbonated beverage, for pressurizing the space above the beverage in the partially used container. In another form, the gas dispenser forms a part of an assembly including a liquid flow tube extending to the bottom of a bottle, a bottle neck seal and a pouring spout, so that the release of gas into the bottle will force the liquid up through the flow tube and out the pouring spout to dispense the liquid.
