Abstract
A variable dosage dropper system improves upon the conventional dropper assembly (container, cap, pipette, bulb) by providing an annular overcap housing which completely encloses the cap and bulb to provide tamper resistant protection and has a locking collar at its lower end to secure the cap within the housing. A plunger slidably, rotatably, and sealingly mates with the housing. The plunger contacts and compresses the bulb when pushed downward toward the housing a predetermined distance corresponding to various dosages and allows the bulb to return to its decompressed position when released. The system is also adapted to resist undesired opening of the container by children.
