ABSTRACT:
A dispensing device for dispensing a measured volume of liquid from a body of liquid contained in a container, which includes a receptacle for receiving an unmeasured excess volume of liquid from the body of liquid and a conduit to connect the container to the receptacle. The conduit permits liquid to flow from the body of liquid into the receptacle when a reduced pressure is created in the receptacle. The device further includes a lid to fit over the receptacle so as to be displaceable relative to the receptacle from a closed position to a dispensing position, the arrangement being such that relative displacement between the lid and receptacle can create a pressure differential between the container and the receptacle to cause liquid to flow from the body of liquid in the container to the receptacle. A part of the conduit serves to adjust the unmeasured excess volume of liquid in the receptacle to the measured volume.
