Abstract

Abstract An eyedrop dispenser is disclosed which includes a plastic squeeze bottle having a dispensing nozzle at one end. A collar overfits the dispenser end of the bottle and carries a pair of cooperating, forwardly extending fingers for eyelid contacting purposes. The fingers terminate forwardly in respective eyelid contactors and one finger is pivotally movable relative to the other to spread the eyelid contactors during the eyedrop dispensing process. The movable finger includes an operator extension which engages the bottle sidewall when the eyelid contactors are separated to squeeze the bottle and dispense the eyedrops.
