Abstract
The present invention is a hinge for a package closure apparatus. A preferred embodiment of the hinge comprises a landing, a spring face, a push-tab, and an air vent. The landing extends from a base of the closure apparatus into an opening of the closure apparatus. The spring face adjoins the landing at a first junction forming a first flexible joint. The push-tab adjoins the spring face at a second junction forming a second flexible joint. The first flexible joint, the spring face, and the second flexible joint cooperate to enable the push-tab to move relative to the base of the apparatus. The air vent is adapted to facilitate a substantially even flow rate of a product through the opening of the closure apparatus.
