Abstract
A closure for opening and resealing a package includes a base attachable to the top of the package over a scored area thereof, and a push tab device pivotally connected to the base at a rearward portion of the base such that a user may depress and end of the push tab into the package thereby creating a central opening area in the package top. The push tab may be provided with a beak and a vent hole. The package top may be partially pre-cut or scored in such a way so as to open in the form of bomb bay doors when the push tab is depressed and rotated into the package. A cover is integrally hinged to the base and is provided for resealing the central opening area.
