Skirted closure for small dropper bottles

Abstract

A closure for a dropper bottle includes a nozzle having a neck and a shoulder. The neck includes an aperture at an end thereof for dropwise dispensing of a liquid, and the shoulder includes an outstanding circumferential ring and threads disposed between the ring and the neck. A cap is provided with a top and an axially downwardly extending skirt. The top has a seat for sealably engaging the aperture, and the skirt has internal grooves for engaging the nozzle threads and an internal circumferential lip for sealably engaging the ring. The lip is spaced apart from the aperture for enabling simultaneous sealing of the aperture and the ring upon rotation of said cap onto said nozzle.

1 . A closure for a dropper bottle, said closure comprising:
