ABSTRACT:
An improved economically disposable dispensing unit is provided for dispensing various measured amounts of a liquid or other freely flowing substance from a container. The position of a movable sleeve within a cup-shaped housing determines the measured amount which will be trapped within a dispensing chamber defined by the housing. The sleeve may be adapted for sliding movement to change positions, or, as an alternative, the sleeve can have a foldable, accordion-like structure which allows adjustment of the sleeve position. The invention can be configured as a disposable, one-piece dispensing unit, wherein one of a plurality of one-piece units, each having a different sized sleeve integrally formed therein, is chosen to select a particular measured amount. The dispensing unit is attached to a container by a flexible spring loop or a plurality of gripping fingers. The dispensing unit can be detached to allow dispensing of medication, or the like, as by drinking directly from the dispensing chamber, or the unit can remain attached to the container during dispensing. In the latter case, a valve covers the sleeve to ensure dispensing of only the measured amount. In one form, the cup-shaped housing is collapsible on the container to a low profile configuration while storing a measured quantity within the dispensing chamber.
