A dispenser construction having a tubular fitment member with an open end, and a stopper member having an annular wall and a side opening therein. The stopper member has a discharge passage communicating with the side opening and a discharge orifice at the end of the discharge passage. The stopper member is carried in the open end of the fitment member, and is axially movable thereon between a raised, discharge position, and a lowered, sealing position. Sealing structures are provided on the open end of the fitment member and on the annular wall of the stopper member, and disposed above the location of the side opening thereof, to prevent leakage of liquid. Valve structures are also provided on the fitment member and stopper member, establishing communication between the open end of the fitment member and the side opening and discharge passage of the stopper member when the latter is disposed in its raised, discharge position, and for blocking communication between the open end of the fitment member and the side opening and discharge passage of the stopper member when the latter is disposed in its lowered, sealing position.
