A metering dispenser assembly comprises a squeeze bottle 1 with a metering cup 3 fitting in the neck of the bottle and carrying a dip tube 9 which extends to the bottom of the bottle. The dip tube, or at least a pillar 7 into which it fits, terminates at a level between the top and bottom of the cup, and there is a vent hole at this level to provide communication between the container and atmosphere. The vent is small enough not to allow significant leakage from the cup during a dispensing operation. The vent could instead be alongside the dip tube.
