ABSTRACT:
A closure and container package are provided in which the closure has an elongated orifice. A spout cover on an underside surface of the cap portion of the closure receives a spout portion on a body portion of the closure about the orifice. A snap hinge couples the cap and body. An interior surface of the spout cover forms a sealing contact with an exterior surface of the spout to form an outside seal that does not become contaminated upon dispensing of the contents of the container. An annular seal extending downwardly from a base portion of the closure seals the head-space within the closure to present vapor infiltration and condensation in the head-space. A mold for forming the closure is also disclosed. The spout may be formed such that its sidewalls outwardly bulge upon molding, but upon cooling become substantially parallel.
