ABSTRACT:
Apparatus for dispensing a measured amount of liquid from a container is adjustable for allowing different measured amounts of liquid to be dispensed from the same container. The apparatus is adaptable for use in the context of two-compartment, squeeze-type containers and two-compartment, inversion-type containers. The latter is a new type of container that allows a measured amount of liquid to be transferred from a storage compartment to a dispensing compartment without the need for an air vent to the outside of the container. The apparatus is designed so that additional liquid from the storage compartment is prevented from entering the dispensing compartment during dispensing of a measured amount of liquid from the container.
