Abstract
A closure cap defining a dispenser port. A stopper tab is pivotally mounted to the closure cap for selectively closing the port. The closure cap includes an end wall having a concave portion defining a camming surface. A resilient finger is provided on the stopper tab and includes a tip portion slidably engaging the camming surface. The finger tip is deflected by its engagement with the camming surface when the stopper tab is arranged in the port-closing disposition so as to bias the stopper tab toward the axis of the pivot portion. The finger tip coacts with the camming surface further to bias the stopper tab pivotally toward an open position wherein the stopper portion is spaced from the port as a result of the stopper tab being moved from the port-closing disposition. The camming surface further coacts with the stopper tab to releasably retain the stopper tab in the fully open pivotal position.
