An easy-opening container of the type commonly used to contain beverages has an end wall that includes a score line and a hinge line with the score and hinge lines together defining a partially separable panel section of the end wall. A pull tab has a ring-shaped lift portion at one end, a finger at its other end and a mounting portion intermediate its ends. The pull tab is mounted at its mounting portion to the end wall adjacent the panel section with the lift portion extending from the mounting portion to overlie and partially frame the panel section and with the finger extending away from the panel section to overlie a portion of the end wall. A locking flange depends from the lift portion to lie in confronting relationship with at least a portion of the periphery of the panel section. The finger is constructed and arranged to engage a portion of the end wall upon movement of the lift portion away from the end wall at least partially separating the panel section from the end wall to define an opening therein. The flange is constructed and arranged to move into locking engagement with the edges defining the opening upon subsequent movement of the lift portion toward the end wall so that the pull tab is maintained in a fixed orientation atop the end wall framing the opening.
