EASY-OPEN ECOLOGY END ABSTRACT OF THE DISCLOSURE An improved easy-opening end structure for use with a container includes a retained tab and a captured panel which is also retained. The end structure includes a scoreline of an improved pinched score variety, defining a pour opening formed by fracture of the scoreline to release the panel formed by the scoreline. Preferably, the panel is retained on the end. The tab is affixed to the end, other than to the panel and includes an opening end positioned over the panel, but not secured thereto, and a lifting end spaced from the panel which is preferably downwardly dished and generally circular in shape. As the lifting end is raised, the portion of the scoreline between the opening end of the tab and the attachment is popped by an upward lift of the end through essentially a class 2 lever action and thereafter the opening end bears against the panel as the tab is raised further to complete rupture of the scoreline by essentially a class 1 lever action and to push the panel downwardly and laterally through the formed opening. The panel may be hinged or fall free into the container. Various types of tabs as well as a method of forming a scoreline and various end structures are described.
