Abstract: A liquid dispenser that is suitable for metering pre-measured quantities of liquid from a rigid wall or deformable walled container. The liquid dispenser comprises a nozzle (16) which attaches to the container at one end and attaches to a dispensing chamber (14) at the other end. The dispensing chamber (14) has an opening (24) at its inlet end which juxtaposes with a disk (21) at the discharge end of the nozzle. The nozzle (16) has a central aperture (19) which terminates at the discharge end with inwardly projecting arms (22) which support the disk (21). The seating of the chamber on the end of the nozzle brings the disk (21) into juxtaposition with the opening (24) to control the flow of liquid from the container to the dispensing chamber (14). When the dispensing chamber (14) is fully engaged with the discharge end of the nozzle (16), the opening (24) in the dispensing chamber interlocks with the disk (21) on the nozzle to prevent the liquid from entering the dispensing chamber.
