Liquid dropper spout having lockable pivoted closure cap

摘要

A dropper bottle assembly with a dispensing closure having a base adapted to be secured to the bottle and an elongated dropper spout extending from the base to a distal open end and with a separate cap defining a cavity sized to receive the spout therein wherein the cap and closure share cooperating hinge and lock structures for pivotably mounting the cap about a fixed axis and locking the cap closed with the spout opening closed off. The lock and hinge structure are formed on the spout below the opening thereof but spaced from the closure base. The lock mechanism includes cooperating teeth and an index finger or a cooperating spring-arm and a grip bar. The spout is sealed by a surface of the cap or a compliant mat on that surface, the latter being held in place by a rib within the cap.
