ABSTRACT:
A closure and container package are provided in which the closure has an elongated orifice. A spout cover disposed on an underside surface of the cap portion of the closure receives a spout portion disposed about the orifice. A spud urges the spout into contact with the spout cover to enhance contact therebetween. A snap hinge couples the cap with the closure body. 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. The spout cover includes a protrusion or bead on an inner surface that cooperates with a bead on the spout exterior surface to lock the cap in its fully closed position. An annular seal extending downwardly from a portion of the closure seals the closure head-space to present vapor infiltration and condensation therein.
