Abstract
This invention consists of an ophthalmic dispensing tip formed by injection molding, which has a one-piece molded tip to be used with a mating cap, the tip having an internally molded breakaway barrier membrane inside the flow channel, and the cap having a shaped stud fitting inside the tip, so that the final clockwise half-turn of the cap pushes the stud against the barrier and displaces it, thereby creating a restricted path through which the contents are dispensed.
