发明名称 PACKAGE CLOSURE AND PACKAGE PREPARATION
摘要 <p>A closure (20) for opening and resealing a package (22) which includes a base (76) attachable to the top (30) of the package (22) over a scored area thereof, and a push-tab (98) device pivotally connected to the base (76) at a rearward portion (80) of the base (76) such that a user may depress an end of the push-tab (98) into the package (22) thereby creating a central opening area (42) in the package top (30). The push-tab (98) may be provided with a beak (112) and a vent hole (118). The package top (30) may be partially pre-cut or scored in such a way so as to open in the form of bomb bay doors (48, 50) when the push-tab (98) is depressed and rotated into the package (22). A cover (120) is integrally hinged to the base (76) and is provided for resealing the central opening area (42).</p>
