ABSTRACT:
A dispensing and metering device which can be attached to the neck of a bottle has a housing defining a chamber having an inlet and an outlet. The chamber can be filled through the inlet with liquid from a bottle secured to the device by an attachment element and can be drained through the outlet. A valve arrangement which includes an outlet nozzle extending generally away from the outlet, is movable from a first condition in which it closes the inlet and opens the outlet, through a second condition in which it closes both the inlet and the outlet, to a third condition in which it closes the outlet and opens the inlet. A flow path is defined at least partly within the valve arrangement for introducing air into the chamber via the nozzle and the outlet. The air replaces liquid flowing from the outlet when the outlet is open. The valve arrangement is resiliently biassed to the third condition to keep the outlet closed until the valve arrangement is operated.
