ABSTRACT:
An improved tear-off closure for a container comprising a top end wall, a depending closure skirt around the top end wall and a pull ring around the bottom edge of the closure skirt. The closure has a pair of score lines therein traversing the skirt and the top end wall to define a tear strip across the closure. The pull ring is integrally connected to the tear strip at the bottom of the closure skirt. A line of separation between the pull ring and the closure skirt extends from a location adjacent the score line on one side of the tear strip around the closure skirt to a location adjacent the score line on the other side of the tear strip. The curved terminal ends of the line of separation are spaced from the tear strip laterally of the score lines on both sides of the tear strip.
