ABSTRACT:
A sheet plastic lid for open-mouthed containers with a tear-away section therein is provided in which the tear-away section is removable by an upward and outward motion. A raised central area of the central web of the lid merges with the top surface of the rim or bead cavity and contains score lines defining a central tear tab and a major portion of the tear-away section, the lines diverging and stopping substantially inboard of the top surface of the bead cavity. Then with the lid on a container, when the tab is freed by penetrating the raised area at the innermost score lines it is pulled upward and outward to constrain the divergent score lines to effect predictable tears through the bead or rim cavity structure to remove the tear-away segment and leave the remainder of the lid intact on the container.
