ABSTRACT:
A molded plastic dispensing closure for attachment to the finish of a container. The closure has a body portion which is directly attached to the finish and a cover portion which is hingedly attached to the body portion and which is foldable with respect to the body portion. The body portion has a dispensing opening therein which is surrounded by an outwardly extending dispensing spout, and the dispensing spout is surrounded by a generally flat annular surface. The cover portion is foldable with respect to the body portion between a first position, in which the dispensing spout is sealed by inner and outer annular sealing fins that are carried by the cover portion, and a second position in which the container is open for dispensing through the body portion. One of the body and cover portions of the closure is provided with a secondary sealing fin which seals against the other portion in an annular pattern that surrounds the generally flat annular surface when the cover portion is in the first position.
