ABSTRACT:
The invention relates to a measuring dispenser adapted to be placed on a closed container of liquid, such as a bottle of medicine, in place of a screw cap or the like. The dispenser is of simplified construction, including an internal open-top dosage receptacle of variable effective capacity, capable of being filled by inverting the container and restoring it to its original position, and a passage connecting the interior of the dosage receptacle with an external delivery point. A separate, independent vent is provided, to eliminate the effects of pressure differences between the ambient atmosphere and the vapor space above the liquid in the container and the dosage receptacle.
