发明名称 EASY OPEN CAN END AND PROCESS OF MAKING
摘要 An easy open end for a container includes an end panel (60) 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 (134) is defined adjacent to and positioned radially inward from the score (81) that defines beneath the score a first outwardly projecting extending cut protection bead (138). A second double fold (136) is defined adjacent to and positioned radially outward from the score (81) that defines beneath the score a second inwardly projecting cut protection bead (140). The end panel is elastically deformed in an area near the score so as to define a concave depression (144) about the score, which provides enhanced cut protection.
