发明名称 Precision release tip for medicinal liquid dropper
摘要 A tip 10 for a liquid dropper 2 is provided which allows liquids such as eye medication to be easily and precisely released from the dropper. The tip 10 is oriented in a substantially horizontal position with an opening 20 in the tip 10 located directly above the targeted area of a patient's eye E. The opening 20 is surrounded by a substantially planar annular face 30 which enhances control of the trajectory of each dispensed droplet D. The annular face 30 encourages the release of each droplet D along the plane formed by the annular face 30. A perimeter ring 40 circumscribes the annular face 30 and abuts a circumambient notch 50. The narrow width 42 of the perimeter ring 40, juxtaposed against the geometric departure of the notch 50, creates an impediment to wettable adhesion of each droplet D to an exterior surface of the tip 10 by minimizing the lateral wettable area available to a droplet D as it exits the opening 20, descends along the annular face 30, then drops toward the eye E of the patient.
