Abstract
A dispensing closure for a container is provided having a cap, a receiving cavity on an outer wall of the cap and a spout rotatably lodged within the cavity. Product from the container can exit through the cap and be dispensed through a channel in the spout when the latter is rotated to a dispensing position. The spout is formed with a pair of flanking wings each having a trunnion/bearing mechanism on an outer surface. The wings are inwardly but not outwardly flexible thereby allowing the spout to be readily snapped into the cavity of the cap during manufacturing assembly
