Abstract
An easy opening container wherein the opening panel is pushed into the interior of the container and wherein, in addition to the opening panel, the single line of weakness also defines a vent panel. The container is provided with an opening tab having a nose divided into first and second nose portions with the first nose portion being operable upon tilting of the opening tab to push in the vent panel to form a vent opening followed by the sequential operation of the second nose portion to push in the opening panel. The second nose portion is interlocked with the container in its fully opened position so that when the opening tab is returned to its initial position only the relatively small and short first nose portion projects into the dispensing opening.
