A method and device for inerting a vat having an upper wall and containing a consumable liquid and an overhead gas, including the steps of: injecting an inerting gas heavier than air by way of a downward extending injection tube into the overhead gas above a free surface of the liquid and substantially below the upper wall of the vat and, during this injection, removing excess gas through the injection tube and a purge orifice of the vat. The injection tube may have a gas diffuser at its lower end.

The invention claimed is: 1. A device for inerting a vat having an upper wall and a single upper opening and containing a consumable liquid and an overhead gas, said device comprising: a downward extending injection tube having an upper end adapted to be connected to said upper opening of the vat and a lower end extending close to a free surface of the consumable liquid in the vat; a tubular connector adapted to be fitted onto the upper opening of the vat, said connector having two concentric passages comprising an inlet for passage of an inerting gas, and an outlet for passage of the overhead gas and a side wall enclosing an upper portion of the injection tube, the side wall being provided with an orifice to purge the overhead gas, and a gas diffuser at the lower end of the injection tube. 2. The device according to claim 1, wherein the gas diffuser has a lower end closed off by a horizontal plate larger than the cross section of the injection tube and the inerting gas is injected through a perforated portion of the diffuser above the horizontal plate. 3. The device according to claim 1, further including a source of an inerting gas heavier than air connected to the injection tube. 4. The device according to claim 1, further including a safety valve connected to the side wall of the connector. 5. The device according to claim 1, wherein the injection tube is adjustable in length. 6. The device according to claim 1, wherein the consumable liquid is wine. 7. The device according to claim 1, wherein the inerting gas comprises a mixture of about 75 to 80% of a neutral gas and the remainder comprises CO2. 8. The device according to claim 7, wherein the neutral gas comprises argon. 9. The device according to claim 1, further including a means for measuring the oxygen level in the overhead gas. 10. The device according to claim 1, further including means for adjusting the pressure of the inerting gas. 11. A device for inerting a vat having an upper wall and a single upper opening and containing a consumable liquid and an overhead gas, said device comprising: a downward extending injection tube having an upper end adapted to be connected to said upper opening of the vat and a lower end extending close to a free surface of the consumable liquid in the vat; a tubular connector adapted to be fitted onto the upper opening of the vat, said connector having an inlet for passage of an inerting gas, an outlet for passage of the overhead gas and a side wall enclosing an upper portion of the injection tube, the side wall being provided with an orifice to purge the overhead gas, and a means for measuring the oxygen level in the overhead gas. 12. In combination, (1) a vat having an upper wall and a single upper opening and containing a consumable liquid and an overhead gas, and (2) a device for inerting said vat, the device comprising: a downward extending injection tube having an upper end connected to said upper opening of the vat and a lower end extending close to a free surface of the consumable liquid in the vat; a tubular connector fitted onto the upper opening of the vat, said connector having two concentric passages comprising an inlet for passage of an inerting gas, and an outlet for passage of the overhead gas and a side wall enclosing an upper portion of the injection tube, the side wall being provided with an orifice to purge the overhead gas, and a gas diffuser at the lower end of the injection tube. 13. The combination or claim 12, wherein the consumable liquid is wine and the inerting gas comprises a mixture of argon and carbon dioxide. 14. The combination of claim 12, wherein the gas diffuser has a lower end closed off by a horizontal plate larger than the cross section of the injection tube and the inerting gas is injected through a perforated portion of the diffuser above the horizontal plate.
