The pouring closure ( 1 ) for liquid packagings ( 2 ) comprises a pouring stem ( 9 ) with a radially projecting bottom edge ( 12 ) and a threaded cover ( 11 ). Threaded cover ( 11 ) has a larger diameter than pouring stem ( 9 ), and an elastically deformable ring element ( 10 ) is disposed between pouring stem ( 9 ) and threaded cover ( 11 ). The ring surface ( 13 ) of the ring element runs obliquely to the ring plane, with the inner ring edge ( 14 ) ending in an downwardly directed projection ( 15 ) which can be clipped over pouring stem ( 9 ). The outer ring edge ( 16 ) ends in an upwardly directed projection ( 25 ), which is provided with an outer thread ( 26 ) for screwing on cover ( 11 ). The ring element ( 10 ) can be elastically deformed to spring into two stable states, namely and firstly, into a state with the ring surface ( 13 ) sloping downwards from the inner ( 14 ) to the outer ( 16 ) ring edge. In this state, the pouring closure ( 1 ) is compressed, and less than 5 mm high. In the other state with the ring surface ( 13 ) rising upwards, the pouring closure ( 1 ) is around three times higher and ensures the liquid can be reliably poured out beyond the 5 mm high rim ( 6 ) of liquid packaging ( 2 ), which is positioned approximately 11 mm distant from pouring stem ( 9 ).
