Definitions

• the invention relates to the field of devices for serving a liquid from a container, the liquid to be stored after opening in a preferably inert gas to prevent it from being degraded.

• the wine oxidizes in contact with the air and loses its properties, which generates a waste of consumption - the rest of the bottle can be lost if it is not drunk quickly, product - great wines are rare - and incidentally finance - great wines are expensive.
• the device must be adapted for that an operator can serve wine from the bottle without too many complications being generated.

This wine is then poured into a glass via an external beak.
• EP1352873 discloses such a solution. Nevertheless, this has several disadvantages.
• the first drawback is the space occupied by the cabinet. This is a piece of furniture-device for serving wine.
• the second disadvantage is the complexity of the device, and therefore its cost, which makes it inaccessible to all catering or hotel services, as well as bars and even more so to individuals.
• the device requires a new apprenticeship to serve wine.
• the third disadvantage is the loss of ritual associated with service and product. The consumer can no longer look at or hold the bottle in his hands, and there is no longer the tilting gesture of the bottle to pour the wine by the glass.

• a second solution is in the form of a portable device that can be mounted on a bottle of wine not opened, when it is desired to pour a glass.

• the bottles of wine concerned generally have a capacity of 75 cl, 150 cl (magnum). In practice, the vast majority of wine bottles have a neck of this size, with the exception of bottles of 37.5 cl and 50 cl.
• a length of 305mm of the device is suitable.
• Bottle of Champagne In the case of a bottle of wine containing a pressurized gas, such as champagne or sparkling wines, the problem of preserving the quality of the wine depends not only on the absence of oxidation, but is also related to the loss of carbon dioxide, which is dissolved in the wine, and which will quickly be released in the air after the opening of the bottle, causing a fundamental organoleptic loss for this type of products, and limiting in fact the glass service of this type of wine.
• the device in question must be able to diffuse a gas comprising a proportion of carbon dioxide (CO2) and another inert gas (nitrogen type, argon ...), or even only carbon dioxide.
• CO2 carbon dioxide
• nitrogen type nitrogen type, argon
• the nature of the gas may therefore be different from the gas used for a non-effervescent bottle.
• the pressure of the gas diffused into the sparkling wine bottle must approach the pressure value of the gas before unclogging (value generally between 1.3 and 5 bar).
• the shutter element 170 is then preferably provided in this case with return means, in the form of a valve or spring, keeping the ball on its seat, up to an adjustable pressure, varying from 1.3 at 5 bar, to prevent the gas from escaping after opening the bottle.
• an activation mechanism in the form of a press button, makes it possible to activate or deactivate the return means of the closure element 170 after and before the service of the wine.
• the pressure of the gas that will be applied in the bottle on the wine by the device limits the loss of bubbles and the oxidation of the wine.
• the neck diameters of these bottles vary between 16.5mm and 20.5mm. In practice, 95% of the internal diameters of wine bottles are between 18 and 19 mm. Therefore, the same device is suitable for several types of bottles.
• the device can easily be adapted, by modifying the dimensions of the holding means 400 and the sealing means 190, and adjusting the length and / or the width of the first part 100.
• the device 10 may comprise a temperature probe (not shown) for measuring the temperature of the wine. Indeed, the temperature of the room is often used to know the temperature of the wine. Thanks to the device provided with a probe, since a portion of the latter is immersed in the fluid F, the knowledge can be improved. wine storage conditions knowing the temperature of the wine itself.
• the probe is positioned in or on the first part 100.
• the probe is at the free end of the first part, to be as often as possible immersed in the fluid F.
• Display means may be provided, in particular on the second part 150, in order to be easily visible by an operator. A battery or battery is then provided to power the system with energy.
• Inert gas Preferably a mixture of dinitrogen and / or argon is used. These mixtures depend on the type of wine and are already known from the state of the art.
• the gas comprises dinitrogen and / or argon, with sulfur dioxide.
• the volume proportion of sulfur dioxide is between 0.1 and 5%, preferably 0.5 and 2%, preferably 1%.
• the gas mixture consists only of dinitrogen, argon and sulfur dioxide.
• carbon dioxide may be added to the gas mixture.
• carbon dioxide can be used.
• This inert gas can be used in any wine preservation device, and in particular in the device presently described.
• the device 10 is essentially made of metal, of the stainless steel type, with the exception of a few elements such as the sealing means 190, for example.
• the capture orifices 130 and degassing 120 are typically made by penetrations in tubes forming the device.
• the device 10 may be formed by a general assembly of different parts, all substantially cylindrical and tubular.
• a weight between 100 g and 300 g is ideal, so as not to disturb the user.
• the device 10 is easy to use and requires almost no training to be used.
• the operator opens the bottle and pours a few centilitres to taste. These few centilitres poured allow to release volume in the bottle to allow the insertion of the device 10 without the wine overflowing.
• the level of wine rises in the neck of the bottle once the device is in place. Because of the generally dark color of the bottle and the presence of opaque wine, most of the device 10 is invisible. Only exceeds the second portion 150 with its fluid pouring means 160. The device 10 therefore takes up as much room as a plug for replacing the cork and remains unobtrusive.
• the longitudinal axis X When standing, the longitudinal axis X is aligned with gravity.
• the two axes of the tilt valve 310 are also aligned with the gravity: the valve 310 is thus in the closed position.
• the tank 100 (and the other integral elements), under its own weight, causes misalignment of the tilt valve 310 and thus triggers its opening ( Figure 6).
• Degassing from the tank 100 to the inside of the bottle, via the expander 140, the control valve 310 and the degassing orifice 120 is then possible: the pressure equilibrium is slightly broken, which allows the flow of The wine then opens the shutter member 170 due to its flow and the pressure prevailing in the container 20 and is poured by the pouring means 160.
• the operator straightens the bottle 20, which causes the realignment of the two axes of the tilt valve 310 in the direction of gravity, and the valve 310 then returns to the closed position.
• the flow of wine ceasing and as the pressure in the container 20 is equal to the external pressure the element shutter returns to its closed position, which blocks the communication channel 152 and isolates the wine from the outside air.
• the capture orifice 130 can not capture all the wine from the bottle 20. However, this prevents the deposit is poured.
• the process may be slightly different.
• the operator activates the deactivation mechanism by pressing the press button. This allows to evacuate the overpressure and allow a free discharge without fountain effect. After payment, the operator releases the deactivation mechanism.
• the bottle can then be vertical, it may be that there has not been enough gas injected from the tank to create the necessary overpressure (that we do not try to have for non-sparkling wine). For this, the operator can then simply tilt the bottle, so as to release gas, until it hears a slight noise at the closure element, corresponding to the evacuation of the overpressure of gas.
• the pressure inside the container 20 is equal to the force exerted by the closure element and return means, that is to say that the pressure reached is that of the pressure storage.
