Abstract: The present invention provides an end closure for a container having a central panel wall with a displaceable opening panel defined by a frangible score and a non-frangible hinge segment. A tab is attached to the panel wall by a rivet, the tab having a nose extending over a first area of the opening panel, the remainder of the opening panel which is exposed from the tab defining the second area of the opening panel. A deboss bead resides in the opening panel, formed in the second area. The deboss bead being curvilinear in shape, formed as a narrow channel in the opening panel. The narrow channel preferably being formed as a U-shaped bead with a first wall and a generally opposed second wall, with the first and second wall being joined by an arcuate intermediate segment. The end closure further has a deboss panel residing in a plane below the remainder of the panel, the deboss bead extending below the plane of the deboss panel.
