Title: Tape seal container closure for liquid containers - has folded over ring pull and dart folds at chick guide grooves
Inventor: NEWMAN FRED C
IPC: B65D17/50
Filed: 1975-05-02
Abstract: The tape seal end closure is for closing pour openings in the end panel of a container. The tape is of rectangular configuration applied to a round end panel and to cover all of the openings extends to an area proximate the circular peripheral seaming chuck guide groove in the end panel. The tape is provided with a ring pull which is folded over the tape and forms corners with the body portion of the tape at its lateral edges. These corners, when the body portion is positioned to adequately cover all of the pour openings in the end panel, project over and encroach upon the chuck guide groove since the proximate edge of the body portion of the tape extends chordally with respect to the groove. Dart folds in there corners clear the groove and unfold when the ring pull is lifted thereby developing the full strength of the tape.
