Abstract
A toggle-action dispensing closure includes a base having an upper edge, and internal thread or bead for securement to a container, and a recessed deck disposed beneath the upper edge and having a fluid dispensing opening. A dispensing disk or actuator is pivotally mounted to the base above the deck, and includes a seal for cooperating with the dispensing opening for selectively opening and closing the dispensing opening. A lug element on a periphery of the disk has a sharp edge in opposed abutment with the upper edge of the base to resist first movement of the actuator to open the dispensing opening. First movement of the actuator to open the dispensing opening causes permanent deformation at the upper edge of the base and/or at the lower edge of the element, such that the element and the edge present lesser resistance to opening of the actuator after such first opening.
