A dispensing means with a viewability of the container from which a liquid such as wine, olive oil or fresh juice is being dispensed and maintaining the liquid free from deterioration or contamination by use of inert gas relative to the liquid. A base unit (4) including an internal reservoir (8) to hold liquids has a top opening (22) that feeds to the reservoir (8) and able to receive the neck (12c) and outlet (12b) of an inverted replaceable bottle (12). A sealing means retains the bottle (12) in position. A dispensing outlet pipe (15) leads from the bottom of the reservoir (8) through an insulation case (7) to an external tap (15b). A gas input (14) leads through a top annular part (13a) on an inner container to the top of the reservoir (8) for supplying an inert gas such as nitrogen, nitrous oxide or argon to the liquid food product.

A liquid dispensing device according to claim 1 wherein the gas is an inert gas relative to the liquid food product such that it does not substantially react with or substantially dissolve into the liquid food product but limits deterioration or contamination of the liquid food product without harmful effects. 3. A liquid dispensing device according to claim 2 wherein the gas is nitrogen or nitrous oxide or argon. 4. A liquid dispensing device according to claim 1 wherein the gas is an inert gas relative to the liquid food product and lays over and covers the liquid food product in the reservoir without harmful effects. 5. A liquid dispensing device according to claim 1 wherein the sealing means includes the opening of the base unit being shaped to closely correspond with the opening of a uniform replaceable liquid receptacle such as a bottle. 6. A liquid dispensing device according to claim 5 wherein the shaped opening includes a throat substantially complementary to a neck of the uniform replaceable liquid receptacle such as a bottle so that the liquid receptacle is held substantially in position and maintains the substantially sealed system. 7. A liquid dispensing device according to claim 1 wherein the gas input into the reservoir is adjacent the opening of the base unit and is able to substantially smother the liquid food product in the reservoir of the base unit when the replaceable liquid receptacle such as a bottle is being replaced. 8. A liquid dispensing device for dispensing a liquid food product such as wine, olive oil or fresh juice such as orange juice the dispensing device having: a base unit having a case, an internal reservoir, a top opening feeding to the reservoir able to receive the outlet of a replaceable liquid receptacle placed in an inverted position over the opening, and a dispensing outlet external of the case feeding from a lower part of the reservoir; a sealing means including a shaped top opening of the base unit being shaped to include a throat substantially complementary to a neck of the uniform replaceable liquid receptacle such as a bottle so that the liquid receptacle is held substantially in position for substantially sealing the opening of the base unit when the outlet of the liquid container is inserted therein to form a substantially sealed system; and a gas injection system includes gas input into the reservoir for supplying an inert gas relative to the liquid food product such that it the gas does not substantially react with or substantially dissolve into the liquid food product but limits deterioration or contamination of the liquid food product without harmful effects, and a pressure regulator controlling the gas content in the substantially sealed system to maintain substantially the pressure equilibrium after dispensing of a portion of liquid from the reservoir through the dispensing outlet, which minimizes the difference in gas pressures from within the liquid dispensing device to outside the device when liquid is dispensed from the reservoir. 9. A liquid dispensing device according to claim 8 wherein the gas is nitrogen or nitrous oxide or argon. 10. A liquid dispensing device according to claim 8 wherein the gas is an inert gas relative to the liquid food product and lays over and covers the liquid food product in the reservoir without harmful effects. 11. A liquid dispensing device according to claim 8 including refrigeration means for cooling the liquid food product in the reservoir or just prior to dispensing outlet. 12. A liquid dispensing system for providing and dispensing wine or other liquid food product by the glass while retaining the remainder of the wine or other liquid food product in substantially sealed condition including the steps of: providing wine or other liquid food product in portable replaceable containers and substantially sealing the replaceable containers airtight; transporting the replaceable containers to the premises of wine or other liquid food product resellers providing wine by the glass; providing each wine or other liquid food product retailer with a liquid dispensing device having a base unit with a reservoir, an opening feeding to the reservoir able to receive the outlet of the replaceable containers, and a dispensing outlet feeding from the reservoir, providing a sealing means for substantially sealing the opening of the base unit when the outlet of the liquid container is inserted therein to form a substantially sealed system; and providing a gas injection system into the reservoir which injects inert gas into the sealed system to allow liquid to be dispensed from the reservoir and to maintain the system with the remainder wine or other liquid food product substantially sealed from the atmosphere preventing spoilage. 13. A liquid dispensing system for providing and dispensing wine or other liquid food product according to claim 12 including the step of mounting the replaceable container on the reservoir in such a manner that the container is viewable to the user or customer such that the product remains and can be seen to remain in an uncontaminated form from the bulk supply to the dispensing means by the mechanical and inert gas system. 14.
