ABSTRACT:
An improved easy-opening container wall and method of forming the same are disclosed. The easy-open container wall comprises a line of weakness in the container wall defining a tear portion at least partially removable from the container wall, a tab having a line of weakness severing nose end, a lifting end, and a hingedly mounted attaching panel located intermediate the ends for permitting hinged movement of a majority of the tab relative to the attaching panel along a hinge line to bring the nose end into forceable engagement with the container wall to rupture the line of weakness and bend a segment of the tear portion inwardly upon lifting the lifting end of the tab, and the tab is attached to the tear portion at locations on both sides of the hinge line to maintain alignment of the tab on the container wall and to provide improved resistance to pulling or tearing the tab material from the container wall at its attachment to the container wall before the container wall can be opened.
