Abstract

A package closure apparatus is disclosed which has a push-tab connected to a base via a landing which extends into a central opening in the closure and a spring face which extends from the push-tab to connect with the landing. The connection between the landing and spring face forms a first junction about which the hinge may act. The connection between the spring face and the push-tab forms a second junction about which the hinge may act.
