Abstract
A flat top thermoplastic coated container and blank including side edge panels, a front edge panel adaptable to being folded back onto itself and having an arcuate-shaped perforated line formed thereon, and a cover panel. The perforated line breaks upon the cover panel being opened to form a horizontal, arcuate-shaped pouring edge. The side edge panels are wider adjacent the cover panel than adjacent the front edge panel to effectively control film delamination upon the cover panel being opened and prevent seepage or "wicking" at the side seam upper edge.
