Abstract
A tamper evident overcap has a tear band which is offset radially from both a ring member sonically welded to a container shoulder and a cap, by generally radially extending frangible bridges. The bridges are severed by applying force to a pull tab extending radially and axially from the tear band in alignment with a gap in the ring member so that there are no undercut faces on the overcap which can consequently be molded in a straight draw mold without cams or slides.
