Dispensing closure, package and method of manufacture

摘要

A dispensing closure includes a base and a lid integrally connected to the base by at least one hinge element for pivoting the lid between a closed position overlying the base and an open position remote from the base. The base includes a deck wall, a skirt coupled to the deck wall and having an internal thread or bead for securing the closure to a container, and a dispensing opening in the deck wall. The lid includes a skirt that surrounds the deck wall in the closed position of the lid. The lid skirt has an interruption at the hinge element into which the hinge element is received in the closed position of the lid. The deck wall has an upstanding part-annular arcuate wall positioned around a peripheral portion of the deck wall adjacent to the hinge element and internally adjacent to an internal surface of the lid skirt at the hinge element to retard entry of moisture through the lid skirt interruption in the closed position of the lid. The lid skirt is free of engagement with the upstanding wall between the open and the closed positions of the lid, which is to say that the upstanding wall serves only to retard entry of moisture through the hinge interruption in the lid skirt and does not affect the function of opening and closing the lid.
