A device for protecting a liquid from oxidation inside a container includes a first element supplying the liquid inside the container, a second element supplying the liquid outside the container and a control unit. A pneumatic control system is configured to produce an overpressure inside the container and on the liquid when the liquid is supplied outside the container, such that, following a decrease in the volume of the liquid inside the container, the pneumatic control system increases its volume by an amount equal to the change in the volume of the liquid. The pneumatic control system includes a variable capacity tank and a pipe supplying and discharging a fluid for filling the tank. A system supplying and discharging the filling fluid is connected to the pipe and the supplying and discharging pipe communicates with the variable capacity tank through a connection placed inside the container at its lower end.

1. A device for protecting a liquid (10) from oxidation inside a container (1) having a first aperture (11) at an upper end, the container (1) further having a first element (5, 50) supplying said liquid (10) inside said container (1), a second element (6, 60) supplying said liquid (10) outside said
1. A device for protecting a liquid (10) from oxidation inside a container (1) having a first aperture (11) at an upper end, the container (1) further having a first element (5, 50) supplying said liquid (10) inside said container (1), a second element (6, 60) supplying said liquid (10) outside said container (1), and a control unit (7), the device comprising: a pneumatic control system at least partially housed into said container (1) and configured to produce an overpressure inside said container (1) and on said liquid (10) when the liquid (10) is supplied outside the container (1), such that following a decrease in volume of said liquid (10) inside said container (1), said pneumatic control system increases in volume by an amount equal to a change in the volume of said liquid (10), said pneumatic control system comprising a variable capacity tank (21) and a pipe (22) supplying and discharging a filling fluid for filling said variable capacity tank (21);a system (3) supplying and discharging the filling fluid that is connected to said pipe (22),wherein said supplying and discharging pipe (22) communicates with said variable capacity tank (21) through a connector placed inside the container (1) at a lower end of the container (1), andwherein said supplying and discharging pipe (22) is in communication with an inside of the container (1) through a lower aperture placed at a bottom of said container (1); anda fastening system placed at the bottom of said container (1) and configured to hold said connector to said variable capacity tank (21) in place,wherein said variable capacity tank (21) is an element composed of a flexible and stretchable material, and has a predetermined volume variable from a specific maximum value, lower than an inner volume of said container (1), and a specific minimum value, corresponding to a condition with no filling fluid or with a smallest amount of filling fluid inside said variable capacity tank (21), said variable capacity tank (21) having a mouth fastened by a peripheral edge thereof to said connector configured for entrance of said filling fluid,wherein said connector comprises two flanges configured to be coupled to each other, andwherein said peripheral edge of said mouth of said variable capacity tank (21) is interposed between the two flanges. 2. The device according to claim 1, wherein the variable capacity tank (21) is configured as a bag having said mouth placed at a bottom thereof, a perimetric shell, wall and a top wall. 3. The device according to claim 1, wherein the pipe (22) supplying the filling fluid and the discharging pipe are composed of a single pipe (22) sealingly connected to said variable capacity tank (21) and alternatively connectable by a three-way valve system to an outer environment and to a filling fluid supply source. 4. The device according to claim 1, wherein said control unit (7) comprises a control member controlling one or both of pressure and the volume inside said container (1), and wherein the control member adjusts an amount of filling fluid to be supplied/discharged into said tank (21) by said supplying and discharging system. 5. The device according to claim 1, wherein said control unit (7) comprises at least one electronic control unit connected to said supplying and discharging system (3) for the filling fluid, and wherein the electronic control unit is configured to generate control signals for adjusting an amount of filling fluid to be supplied/discharged inside said tank (21). 6. The device according to claim 5, wherein said control unit (7) comprises at least one sensor detecting the volume of the liquid inside said container (1), such that generation of said control signals by said electronic control unit occurs automatically based on a liquid level detected by at least one sensor. 7. A kit for making a device for protecting a liquid from oxidation on an already existing container (1) comprising: a pneumatic control system comprising a variable capacity tank (21) and a pipe (22) supplying and discharging a fluid filling said variable capacity tank (21);a control unit (7);a system supplying and discharging the filling fluid which is connected to said pipe (22) with a connector; anda fastening system placed at the bottom of said container (1) and configured to hold said connector to said variable capacity tank (21) in place,wherein said pneumatic control system is at least partially housed into said container (1) and configured to produce an overpressure inside said container (1) and on said liquid (10) when said liquid (10) is supplied outside the container (1), such that following a decrease in volume of said liquid (10) inside said container (1), said pneumatic control system increases in volume by an amount equal to a change in the volume of said liquid (10), said pneumatic control system comprising said variable capacity tank (21) and said pipe (22) supplying and discharging said filling fluid for filling said variable capacity tank (21),wherein said pipe (22) communicates with said variable capacity tank (21) through a connector placed inside the container (1) at a lower end of the container (1),wherein said supplying and discharging pipe (22) is in communication with an inside of the container (1) through a lower aperture placed at a bottom of said container (1),wherein said variable capacity tank (21) is an element composed of a flexible and stretchable material, and has a predetermined volume variable from a specific maximum value, lower than an inner volume of said container (1), and a specific minimum value, corresponding to a condition with no filling fluid or with a smallest amount of filling fluid inside said variable capacity tank (21), said variable capacity tank (21) having a mouth fastened by a peripheral edge thereof to said connector configured for entrance of said filling fluid,wherein said connector comprises two flanges configured to be coupled to each other, andwherein said peripheral edge of said mouth of said variable capacity tank (21) is interposed between the two flanges.
