A toggle-action dispensing closure for a container is provided for manipulation between a closed, non-dispensing orientation and an open, dispensing orientation. The closure includes an actuator pivotally mounted along a tilting axis on a body secured to the container. The actuator is tiltable by applying force to the actuator on one side of the tilting axis so as to move the actuator from a non-dispensing position to a dispensing position. The actuator includes a striker rib extending downwardly at a position between an edge of the actuator and the tilting axis. The body includes a deck defining a dispensing aperture and supporting a post. The post extends vertically to underlie the actuator, preventing tilting of the actuator unless a sufficient opening force is exerted on the actuator to cause the striker rib to shear, or permanently deform, the post. One embodiment includes an angled fracture control surface at the bottom of the post to ensure that the initial minimum required force to shear the post is within a desired range.

[ What is claimed is:] [1.]1. In a toggle-action dispensing closure for an opening to a container wherein said closure includes:a body for engaging said container over said opening and defining a discharge aperture communicating with said opening; andan actuator pivotally mounted about a tilting axis on said body for occluding flow from said container through said discharge aperture when said actuator is in a closed, non-dispensing position and for permitting flow from said container when force is applied to said actuator to tilt said actuator to an open dispensing position, said body having a movable abutment under said actuator for confronting said actuator when said actuator is in said non-dispensing position to prevent tilting of said actuator to said dispensing position in response to said actuator being subjected to a force less than a predetermined force, but said abutment being moved by said actuator when said actuator is subjected to at least said predetermined force so that thereafter said actuator can be tilted to said dispensing position in response to the application of force less than said predetermined force, the improvement comprising:said actuator comprising a pressing surface on an outside thereof for forcible pivoting of said actuator to said dispensing position, said pressing surface extending to an edge of said actuator at a distance from said tilting axis, and said actuator comprising a striker rib extending from an inside of said actuator and located between said tilting axis and said edge, said striker rib arranged and configured to confront said movable abutment and to move said movable abutment to allow said actuator to pivot to said dispensing position, the distance from said tilting axis to said striker rib being about 65% of the distance from said tilting axis to said actuator edge to increase the mechanical advantage of the application of force to said abutment.
