An apparatus for adding, from a gas container with a gas under an overpressure via a pressure reducing valve unit to a bottle fully or partly filled with a liquid while utilizing a two-part valve arrangement. The first part of the arrangement is related to the valve unit and a second part of the arrangement is related to the bottle. The two parts of the valve arrangement are easily coordinated with each other and easily separable. One valve part is adapted to enclose a first check valve which, when being mechanically influenced, allows gas flow from the container and into the bottle. The other valve part is adapted to enclose a second check valve which, when being pneumatically influenced, allows gas flow into the bottle.

1. An apparatus for adding, from a gas container with a gas, put under an overpressure, said gas, via a pressure reducing valve unit, to a bottle fully or partly filled with a liquid comprising a two-part valve arrangement, wherein a first part of the arrangement is related to the container and its valve unit, and a second part of the arrangement is related to the bottle, wherein the first and second parts of said two-part valve arrangement are connectable with each other and separatable from each other, where the first part includes a first check valve which is mechanically openable to allow a gas flow from the container via the valve unit and into the bottle, whereas the second part includes a second check valve which is pneumatically openable to allow a gas flow from the first check valve and into the bottle, whereas said first and second check valves, when the first and second parts are separated from each other, are adapted to arrest the gas flow with the first check valve arresting gas flow from the gas container and the second check valve arresting gas flow back from the bottle, wherein the first part includes an attachment configured to be fixed to a wall section and a tube or a pipe is adapted to extend from a shaped attachment within said first part to the pressure reducing valve unit related to the container. 2. The apparatus according to claim 1, wherein the first part is shaped with an upwardly directed pipe section, whereas the second part is shaped with a channel, adapted to enclose said pipe section in an interacting position. 3. The apparatus according to claim 2, wherein the second part includes said channel and, laterally arranged with respect to said channel, an upper open portion of the bottle provided with an outer thread, which can be coordinated with a seal provided with an inner thread. 4. The apparatus according to claim 3, wherein said seal includes a pipe section intended for a gas flow, dimensioned with a length so as to allow its orifice to be located below a surface of a contained liquid. 5. The apparatus according to claim 1, wherein the bottle consists essentially of a plastic bottle, dimensioned to be able to withstand an overpressure less than the overpressure for the container. 6. The apparatus according to claim 3, wherein between the seal and the upper open portion of the bottle there is provided a gasket, wherein the first check valve includes a first valve seat that is urged into the closed position by a spring and mechanical opening of the first check valve moves the seat to allow gas flow from the container toward the bottle;wherein the second check valve includes a second valve seat that is urged into a closed position by a spring and pneumatic opening occurs when the first check valve is mechanically opened and the gas pressure moves the second check valve into the open position against the urging of the spring and pressure in the bottle. 7. The apparatus according to claim 2, wherein the second part includes said channel and, laterally arranged with respect to said channel, an upper open portion of the bottle provided with an outer thread, which can be coordinated with a seal provided with an inner thread. 8. The apparatus according to claim 7, wherein said seal includes a pipe section intended for a gas flow, dimensioned with a length so as to allow its orifice to be located below a surface of a contained liquid. 9. The apparatus according to claim 3, wherein between the seal and the upper open portion of the bottle there is provided a gasket. 10. The apparatus according to claim 7, wherein between the seal and the upper open portion of the bottle there is provided a gasket. 11. The apparatus according to claim 1, wherein the two-part valve arrangement is adapted to provide CO2 gas from the container into the bottle. 12. The apparatus according to claim 1, wherein the first part is remote from the second part and the first part and second part are fluidly connected by the tube, which is elongate. 13. The apparatus according to claim 1, wherein the second part is normally closed to gas flow to the bottle and is opened to gas flow when the first part is mechanically opened and pressurized gas is delivered to the second part through the first part. 14. An apparatus to add gas from a pressurized container to a bottle, comprising: a first valve part fluidly connected to the container, the first valve part including a first check valve with a normally sealed position and an unsealed position, wherein the first valve part is mechanically movable from the sealed position to the unsealed position to allow gas to flow from the container, wherein the sealed position prevents forward flow from the container;a second valve part in fluidly connected to the first valve part and the bottle, the second valve part including a second check valve with a normally closed state and an open state, wherein the second valve part is pneumatically movable from the closed state to the open state upon receipt of pressurized gas from the first valve part to allow gas to flow into the bottle and in the closed state arrests flow of gas from the bottle, which is in an opposite direction relative to the flow of gas from the container to the bottle with both the first valve part and the second valve part being in an unsealed state and an open state, respectively;wherein the first part is fixed to a support section; andwherein the second part is fixed to the support section. 15. The apparatus of claim 14, wherein the second valve part is moved vertically downwardly to mechanically engage the first valve part to unseal the first valve part for gas flow from the container. 16. The apparatus of claim 14, wherein the second valve part includes a valve cone urged into the closed state via a spring with force less than the pressurized gas. 17. The apparatus of claim 16, wherein the first valve part includes a tube with a channel with a lower region and a valve cone connected to the tube and pressed to the sealed position by a pressure spring, wherein the lower region of the channel includes two channel branches fluidly open to the container with the first valve part in the unsealed position and closed to the container with the first valve part in the sealed position. 18. The apparatus of claim 17, wherein the second valve part includes a pipe section in fluid communication with the tube of the first valve part with the first valve part coordinatingly receiving the second valve part, and the second valve part is pressed downwardly onto the first valve part against the tube to unseat the tube and move the first valve part to the unsealed position to allow gas to flow into the channel branches through the channel and the pipe section. 19. The apparatus of claim 18, wherein the valve cone of the first valve part is further urged to the sealed position by gas pressure from the container. 20. The apparatus according to claim 1, wherein the first check valve has a normally closed position and is held in an open position when installed to provide gas, and wherein the second check valve has a normally closed position to prevent gas from flowing back from the bottle and is configured to move to an open position with gas pressure from the container through the first check valve.
