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. The deboss bead is formed in the manufacturing operation of the score formation and is formed simultaneous with the formation of the score to draw up loose metal from the score incising of the metal.
