Abstract
This invention provides a method of and an apparatus for preservation of the contents of a part filled beverage container, such as an opened wine bottle (2). The method comprises the steps of removing gas from the container (2) until a first predetermined pressure is achieved; and supplying an inert gas to the container until a second predetermined pressure is achieved. To preserve the contents of a sparkling wine bottle, it is possible to supply a pressurising gas to the container until a third predetermined pressure is reached.
Description
- This invention relates to preservation of the contents of beverage containers, in particular to preserving the contents of still and sparkling wine bottles once some of the wine has been removed. However, the invention can equally well be used with other beverages and other type of containers, for example wine barrels.
- It is known to preserve still wine in wine bottles by evacuating the air space above the liquid once some of the wine has been consumed. It is also known to preserve sparkling wine in wine bottles by pumping air or carbon dioxide into the bottle to prevent the wine from losing its sparkle.
- However, a problem with such known systems is that the residual air (and hence oxygen) in the bottle allows some oxidation of the contents to occur. Furthermore, some beverages may deteriorate if kept at a sub atmospheric pressure for a sufficient length of time.
- This invention seeks to reduce the amount of residual oxygen in a beverage container in order to increase the length of time for which a preserved beverage may be stared, and seeks to avoid the need to store a beverage at a sub atmospheric pressure.
- In its broadest aspect, the invention provides apparatus for preserving the contents of a part filled container, the apparatus comprising a stopper with a bi-directional valve, adapted to be removably fitted in an aperture of the container; means for extracting a gas from the container, through the valve in the stopper; and means for introducing a gas into the container, through the valve in the stopper.
- The invention also provides an apparatus for preserving the contents of a part filled container, the apparatus comprising a bidirectional valved stopper, adapted to be removably fitted in an aperture of the container; a vacuum source communicating with a socket of the apparatus via a first pneumatic circuit, the socket being adapted to form a seal with the stopper, the vacuum source being arranged, in operation, to remove gas from the container via the stopper to create a sub atmospheric pressure inside the container; means for disconnecting the vacuum source once a first predetermined pressure has been achieved inside the container; an inert gas source communicating with the socket via a second pneumatic circuit, the inert gas source being arranged to supply inert gas into the container via the stopper once the vacuum source has been disconnected; and means for ceasing the supply of inert gas once a second predetermined pressure has been achieved inside the container.
- The vacuum source is preferably a vacuum pump, and the means for disconnecting the vacuum source may comprise a switch which switches off and stops operation of the pump.
- By replacing air, and its oxygen content with an inert gas in a part filled container it is possible to slow the rate of oxidation and hence deterioration of the contents. As the percentage of oxygen in air is known (approximately 18%) and the percentage of remaining air/gas at the first predetermined pressure is known, it is possible to quantify the residual oxygen content after a cycle of removal of gas followed by supply of the inert gas. Two or more cycles may be completed in order to further dilute the residual oxygen content and therefore further increase the possible period of preservation. Alternatively the level of vacuum (ie the first predetermined pressure) may be increased with the same result.
- In the preferred embodiment of the invention the bi-directional valved stopper is a stopper incorporating a flutter valve. The flutter valve is preferably arranged, once a cycle is complete, to retain a small residual pressure differential between the atmosphere inside the container and the ambient atmosphere outside.
- In the case of still beverages, the pressure inside the bottle will be slightly superatmospheric, so that the slight residual pressure prevents the ingress of air if the container (for example a bottle) is cooled or refrigerated. In other embodiments the stopper could incorporate two non return valves which operate to prevent flow in different directions, for example.
- For the preservation of sparkling beverages it is desirable to apply a superatmospheric pressure to the part filled container in order to prevent the beverage from losing its sparkle. This can be done after replacing air and its oxygen content with an inert gas, thus ensuring that the beverage neither oxidises nor loses its effervescence.
- Therefore, for preservation of sparkling beverages the apparatus further comprises a second gas source communicating with a socket, the second gas source being arranged, in operation, to supply gas into the container via the stopper; and means for ceasing the supply of the gas once a third predetermined pressure is reached.
- It would be possible for the two operations, i.e. the replacement of residual oxygen by an inert gas, and the application of a head pressure to be carried out via the same socket. However, for ease of use by bar staff, in the preferred embodiment there are two sockets one for the replacement of residual oxygen by an inert gas, and a second for the application of a head pressure from a second gas source.
- Before offering a sparkling beverage container to the socket for application of the head pressure it is preferable if a second stopper (designed to fit snugly over the first stopper) is fitted. The second stopper has a retention device to stop it from being blown apart from the first stopper, and a non return valve to allow the head pressure to be applied and retained.
- Argon is a preferred inert gas, because argon is particularly effective for inhibiting the evaporation of any dissolved oxygen present in a liquid in the part filled container. Carbon dioxide is preferred as the gas for creating the head pressure. It would also be possible to use carbon dioxide as the inert gas so that only a single gas supply is required.
- Preferably, the means for stopping the pump from pumping through the valve is also arranged to activate the supply of inert gas. The means for stopping the pump from pumping through the valve and for ceasing the supply of the inert gas or the head pressure gas are conveniently implemented by the use of pressure sensitive switches located in the appropriate pneumatic circuit, and arranged to operate once the appropriate sub atmospheric or super atmospheric pressure is reached.
- Such switches may be arranged to actually stop the pump or supply or they may be arranged to close a valve in the appropriate pneumatic circuit, or both.
- Part of the or each socket can be spring loaded relative to a switch which starts the pump operation or the supply of the second gas so that the socket can be: displaced by offering the container to the socket, causing the switch to operate.
- According to a second aspect of the invention there is also provided a method for the preservation of the contents of a part filled beverage container, comprising the steps of removing gas from the container until a first predetermined pressure is achieved; and supplying an inert gas to the container until a second predetermined pressure is achieved.
- The above steps may be performed a number of times in order to repeatedly dilute the amount of residual oxygen remaining in the part filled beverage container.
- This method may be used for the preservation of sparkling beverages by including the further step of supplying a gas under pressure to the container until a third predetermined pressure is reached.
- According to another aspect of the invention, there is provided a stopper for a wine bottle, the stopper having a skirt to seal against the neck of a wine bottle and a bi-directional valve which can open to allow flow through the stopper in either direction when a pressure differential above a threshold level is applied in either direction across the stopper, and which remains closed when a pressure differential below said threshold is applied.
- The bi-directional valve is preferably a flutter valve and the stopper is preferably a one-piece moulded product of an elastomer material, with the lips of the flutter valve being integral with the stopper.
- The invention is particularly intended for and adapted to the preservation of wine contained in conventional glass bottles, and may be installed behind a bar where a selection of wines is available for sale. It is simple for a bar tender to dispense one glassful from a part-consumed bottle, to insert the stopper and offer the bottle up to the apparatus so that the air in the headapace, and its oxygen content, can be evacuated from the bottle.
- Stoppers may be used which are colour coded to indicate the ideal frequency for the replacement of residual oxygen by an inert gas to be performed, in dependence upon the expected turnover of the particular product. For example, black may indicate a fast moving product which requires the operation to be performed once at the end of service. Silver may indicate a product which requires the operation to be performed once after each glass of wine is served, and gold may be used to indicate a product which requires the operation to be performed twice after each glass of wine is served.
- Embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings in which
-

The bottle and stopper are then offered up to asocket 3. The socket is connected to astrike plate 5 for operating a switch 4. Thestrike plate 5 is biased such that a switch 4 is usually in the off position.

The vacuum pump 6 serves to withdraw air from the headspace of the part filledbottle 2 through thestopper 1 via a first pneumatic circuit. - The
stopper 1 incorporates a flutter valve (seeFIG. 2 ). This valve will retain a small pressure differential between its two sides (eg 0.1-0.15 bar), irrespective of which side is at a higher pressure and which side is at a lower pressure. The valve will however open to allow flow from one side to the other when a pressure differential above a certain level is applied across the valve. - A pressure sensor 9 is arranged to detect a first predetermined pressure, which is a subatmospheric pressure.

In this embodiment of the invention argon is pumped through the second pneumatic circuit, although it would be possible to allow the argon to be drawn through the circuit by the pressure differential which has been created. - A
second pressure sensor 16 is arranged to detect when a second predetermined pressure has been achieved. This second predetermined pressure is just above atmospheric pressure, for example 1.1 to 1.2 bar.

Theamber neon bulb 7 then goes out and a green neon bulb-lights up to indicate operation complete. - In the event that the supply of argon is exhausted the
second pressure sensor 16 does not operate and thegreen neon bulb 15 does not light up. The operator will then know that the operation has not been properly completed. - Removing the
bottle 2 causes the switch 4 to return to the off position. Thegreen neon bulb 15 goes out and the apparatus is reset and ready for the next operation. - When the stopper is removed to allow more of the container contents to be dispensed, there will be a small rush of gas out of the container.
