ABSTRACT:
An innerseal liner for containers is provided which permits the removal of the entire liner from the mouth of a container without any tearing of the liner. The innerseal liner is sealed to the mouth of the container and a portion of the outer circumference of the liner overhangs the outer surface of the mouth of the container. A pull tab is integrally formed with the innerseal liner and at the intersection of the pull tab with the circular portion of the liner are cut-outs in the circular periphery of the liner. The cut-outs may be arc-shaped and are of a depth approximately the same as the width of the overhang portion of the innerseal liner so that when the pull tab is pulled, the innerseal is removed from the mouth of the container along an arc approximately equal to the width of the pull tab and the length of the cut-out portions before the overhang portion of the liner is lifted from the mouth of the container.
