ABSTRACT:
An easy open end for a container includes an end panel having a score defined therein that defines a removable end panel portion. The score is preferably notched to define a bottom edge having a continuous V-shaped recess. A first double fold is defined adjacent to and positioned radially inward from the score that defines beneath the score a first outwardly projecting extending cut protection bead. A second double fold is defined adjacent to and positioned radially outward from the score that defines beneath the score a second inwardly projecting cut protection bead. The end panel is elastically deformed in an area near the score so as to define a concave depression about the score, which provides enhanced cut protection.
