The invention claimed is: 1. A drinking mouthpiece for liquid container, including a valve assembly arranged on a lid including an opening for the passage of liquid, wherein the drinking mouthpiece is substantially elastic and the valve assembly includes a flexible membrane having at least one valve opening and a substantially rigid membrane supporting element having at least one valve opening, wherein the membrane supporting element is supported by a web connected with a fastening ring for securing the membrane supporting element to the lid, wherein the fastening ring is spaced apart from the membrane supporting element in a longitudinal direction of the drinking mouthpiece wherein, with the valve assembly being in a closed position, the membrane rests on the membrane supporting element and the valve opening of the membrane is sealingly covered by the membrane supporting element and the valve opening of the membrane supporting element is sealingly covered by the membrane, the membrane being inwardly curved in said closed position, wherein during the external application of pressure to the drinking mouthpiece and/or the application of an underpressure at the membrane side facing away from the membrane supporting element, the membrane is in a resnapped, outwardly curved open position in which the valve openings of the membrane and membrane supporting element, respectively, are released. 2. A valve assembly according to claim 1, wherein the membrane is substantially conical in its closed and open positions. 3. A valve assembly according to claim 1 wherein the membrane supporting element comprises a valve seat surface substantially corresponding with the inwardly curved shape of the membrane in its closed position. 4. A valve assembly according to claim 1, wherein the drinking mouthpiece comprises a latch groove intended to receive the membrane supporting element configured as a latch body. 5. A valve assembly according to claim 1, wherein the drinking mouthpiece is designed to be substantially oval in top view. 6. A valve assembly according to claim 5, wherein the web used to fasten the membrane supporting element is designed in a plate-shaped manner with the plane defined by the plate-shaped web extending in the direction of the longer axis of the drinking mouthpiece in top view. 7. A valve assembly according to claim 1, wherein the membrane comprises several valve openings arranged along a circular line. 8. A valve assembly according to claim 1, wherein the membrane supporting element comprises a substantially central valve opening. 9. A valve assembly according to claim 1, wherein the mouthpiece, formed as a drinking spout, extends beyond the membrane, whereby an elevated drinking spout edge is formed as a membrane protection and spacer element. 10. A valve assembly according to claim 1, wherein the drinking mouthpiece is made of an elastomer material. 11. A valve assembly according to claim 1, wherein the membrane supporting element is made of polypropylene (PP). 12. A drinking mouthpiece according to claim 1, wherein the soft drinking mouthpiece is produced by a multi-component injection molding process in one piece with the hard lid. 13. A drinking mouthpiece according to claim 1, wherein the lid includes an air valve having an annular membrane and at least one air passage opening, wherein a reception element including a peripheral groove to the inner side of the lid and comprises at least one air entry opening communicating with the air passage opening of the lid and leading into the groove, wherein a ring is insertable or inserted in the groove and the air entry opening is sealed at equal pressures on either side of the air entry opening and at an overpressure at the inner side of the lid, due to the bias of at least one groove wall designed as an annular membrane, and the air entry opening is released at an underpressure at the inner side of the lid. 14. A drinking mouthpiece according to claim 13, wherein the end region of the ring facing the air entry opening of the reception element in the inserted position of the ring is designed to be substantially conical in cross section. 15. A drinking mouthpiece according to claim 13, wherein the end region of the ring facing the air entry opening of the reception element in the inserted position of the ring comprises at least one recess. 16. A drinking mouthpiece according to claim 13, wherein the ring is fixable or fixed in the reception element by the aid of a snap connection. 17. A drinking mouthpiece according to claim 16, wherein the ring comprises on its outer side a circumferential bead for snapping into the groove of the reception element. 18. A drinking mouthpiece according to claim 13, wherein the inner groove wall is designed as an annular membrane. 19. A drinking mouthpiece according to claim 13, wherein the annular membrane comprises at least one thin spot to fix the bias of the annular membrane. 20. A drinking mouthpiece according to claim 13, wherein the fastening ring extending in the direction of the lid opening is connected with the ring via an inwardly extending connection flange. 21. A drinking mouthpiece according to claim 20 wherein at least one ventilation opening is provided in the connection flange. 22. A drinking mouthpiece according to claim 21, wherein the ventilation opening of the connection flange, in the inserted position of the ring, is located adjacent to the inner groove wall designed as an annular membrane. 23. A valve assembly according to claim 10, wherein the drinking mouthpiece is made of a thermoplastic elastomer (TPE). 24. A drinking mouthpiece according to claim 12, wherein the soft drinking mouthpiece is made of a thermoplastic elastomer (TPE), and the hard lid is made of polypropylene (PP).
