Abstract: A tip is provided for a liquid dropper which facilitates formation of a mini drop, a mini drop being a drop smaller than a standard typical drop. A conduit is provided extending from a reservoir of liquid to a tip. The tip provides a location for release of the mini drop. The tip includes a rim surrounding a port with the rim having a particularly thin wall and with the port being particularly narrow. The dimensions of the rim and port facilitate formation of the mini drop. The material forming the tip is flexible and resilient so that should the tip come into contact with sensitive structures, such as an eye of a patient, a potential for injury is minimized. Dispensers featuring the unique tip are disclosed in multiple different embodiments for attachment to a bottle of liquid to be dispensed, or to fit over an existing outlet.

Abstract: An eye dropper bottle 20 is provided which allows a person to instill drops D into an eye E while the bottle 20 is held in a near horizontal orientation 22. The bottle 20 has a reservoir 51 for holding a liquid 59. The reservoir 51 includes a base 52, an upper end 50, and compressible walls 55. The bottle 20 further includes a neck 40 into which a dropper tip 34 fits. The neck 40 has external threads 42 onto which an internally threaded 32 cap 30 fits. The internal surface 56 of the walls 55 of the reservoir 51 maintains a constant slope 58 of a predetermined angle to allow virtually all the liquid 59 of the reservoir 51 to flow toward a dropper tip 34 where it can be discharged in the form of drops D while the bottle is held in a near horizontal orientation 22. The bottle 20 is grasped with a thumb T parallel to the length of the bottle 20 and an index finger F wrapped around a sulcus 48.

Abstract: A dropper tip 30 is provided which allows a person to instill a drop D into and eye E from a bottle 20 that has compressible and resilient walls 19 while the bottle 20 is held in a horizontal orientation. The dropper tip 30 includes an internal passage 37 into which a stem 35 is inserted. The stem 35 has a groove 36 along its peripheral surface which allows the flow of liquid 21 from the reservoir 20 to the free end 29 of the tip 30. The stem 35 protrudes from the external opening 44 of the internal passage 37 of the tip 30 and has a head 33 on the protruding end. The drop D adheres to the head 33 rather than adhere to and migrate along the external surface 28 of the tip 30. The dropper tip 30 further includes an annulus 32 at the free end 29 of the tip 30 which encircles the external opening 44 of the internal passage 37. The annulus provides a surface for a drop D of liquid 21 to adhere to while awaiting release.

Abstract: 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.

Abstract: A dropper 10 is provided which allows a person to precisely instill eye drop solution while the person's head and the dropper 10 are oriented in an upright position. The dropper 10 includes a deformable, resilient reservoir 40 of medicinal fluid which may be squeezed to to cause the fluid to flow up a supply conduit 15 to a housing 20 of the dropper 10. The fluid then flows out an opening 32 in a tip 31 of the dropper 10. An inner rod 130 or inner delivery tube 30 extends along an interior of the supply conduit 15. The tube 30 or rod 130 discourages air bubbles from being entrapped within the conduit 15. The tip 31 extends forward from a center line 41 along an extension 27 which is substantially perpendicular to a collar 50 extending up from the reservoir 40.
