A dual function integrated valve comprising two cavities (2 and 2a), within same unit, a liquid outlet cavity (2), and air inlet cavity (2a), said cavities open or close by elastic action connected to plugs at the upper exits of said cavities in the form of membrane (5), and when suction is applied, plugs lift to allow liquid to flow outwards through perforations in the membrane (5), and air inwards through inlet holes (6 and 6a) on cavity (2a) and s pout wall (1), and both outlets are blocked once suction seizes and plugs return to their original position, due to elastic tension in the membrane thus turning the drinks vessels into non-spill ones. |
