Abstract
A liquid dispenser includes an outer tube (2) with a discharge opening formed in its side wall and an inner tube (4), which is at least partially accommodated within the outer tube and defines with it an annular space, which accommodates an annular sealing member (20), which forms a peripheral seal with the inner and outer tubes. The other end of the outer tube is adapted for connection to a liquid container. A liquid flow opening (30) is formed in the wall of the inner tube and the inner tube is movable longitudinally within the outer tube between an open position, in which the liquid flow opening communicates with the discharge opening (14), and a closed position, in which the liquid flow path is sealed. An air flow passage with two ends is formed in the inner tube, which is so arranged that when the inner tube is in the open position one of the ends communicates with the discharge opening and the air flow passage.
