A liquid dispenser, such as a tap for a liquid container particularly a wine box, includes an outer tube ( 2 ) with a discharge opening ( 14 ) formed in its side wall and an inner tube ( 4 ), which is at least partially accommodated within the outer tube ( 2 ) and defines with it an annular space, which accommodates an annular sealing member ( 20 ), which forms a seal with the outer tube. One end of the inner tube ( 4 ) is closed and one end of the outer tube ( 2 ) is integrally connected to the inner tube ( 4 ) by a flexible, integral annular web ( 10 ), whose width in the radial direction is greater than that of the annular space. The other end of the outer tube ( 2 ) is adapted for connection to the liquid container. The inner tube ( 4 ) is movable longitudinally within the outer tube ( 2 ) between an open position, in which there is a liquid flow path between the said outer end of the outer tube and the discharge opening ( 14 ), and a closed position, in which the outer surface of the inner tube ( 4 ) forms a sliding seal with sealing member ( 20 ) and the said liquid flow path is sealed.
