ABSTRACT:
An improved bottle closure having a dropper, wherein the rubber suction element of the dropper has a posterior end, extending through the closure element, and an anterior end defined by a conventional suction tube. An annular bearing element of the suction element is adapted to seal against the top of the container, so that as the closure element is tightened onto the container, a section of the suction element is axially shortened between the bearing element and a point of connection with the closure element. Hence, as the closure element is removed, a predetermined amount of fluid will aspirate into the anterior end of the suction tube of the dropper.
