Abstract: A carton having a rectanguloid, cylindrical or other conventional shape formed from suitable material has a plurality of walls arranged to define a container body. One of the plurality of walls of the container body is provided with a section having two panels arranged in a gradually deepening infolded V shape beginning at a point within the one wall and extending to another of the plurality of walls intersecting and adjacent the one wall, the section being of its greatest depth at the intersecting adjacent wall. A pull tab extends along the axial centerline of the section. In one embodiment tabs are adhesively joined to the panels and are attached along the edge of the intersecting adjacent wall along lines of weakening. In alternative embodiments, the panels are attached to the edge of the intersecting adjacent wall along lines of weakening.
