Abstract
A paperboard container having a side wall formed from a single blank. A band or zone along one edge of the blank is provided with a plurality score lines each of whose edges are non-parallel to thereby yield a wedge score indentation. The blank is rolled to assume a round or rectangular cross-section tube, and the band is bent inwardly and sealed against a closure disc or panel. By virtue of the wedge shape of the scores, the resultant gathers in the band are substantially confined within the wedge scores to yield a more uniform seal between the inwardly bent band and the closure disc or panel.
