A valve closure for dispensing liquid by means of a pressurised gas has an inner sleeve () which includes a socket () and an annular inner valve seat (). The inner sleeve carries a ring seal () which is urged against an outer valve seat () by an outer spring (). A valve member () has an annular sealing face () co-operable with the inner valve seat () and a spring () urges the valve member () against the inner valve seat (). The valve member () incorporates a plurality of projections () spaced radially from the annular sealing face (). The valve closure can be used with a dispensing coupler having a tubular probe inwards with a circumferential ring seal and a locking recess to engage the locking fingers of a detachable closing element. 1.
