ABSTRACT:
An easy-open container having a wall in which an openable member is integrally formed and defined by a selectively separable region. The openable member has an opening tab which is raised outwardly from the container wall, with the opening tab having a flange which overhangs at least part of the separable region. Finger pressure applied inwardly onto the opening tab toward the container wall causes the separable region to become ruptured, allowing the openable member to move inwardly with respect to the wall. Inward movement of the openable member is limited by the overhanging flange which contacts the periphery of the opening. In some embodiments, the separated opening member is retained on the container wall and is then displaced to reveal an opening in the container wall for access to the contents of the container. In other embodiments, the opening member becomes detachable from the container wall. Several openable members are disclosed which can reclose the opened container. The opening tab may be an integral part of the openable member, or may be a separate element which is attached to the openable member.
