<p>A flat top closure of a thermoplastic coated container and blank includes side edge panels 40 and 42, a front edge panel 46 foldable back onto itself and having an arcuate-shaped perforated line 70 formed thereon, and a cover panel 44 having cover edge panels 72 and 74 connected to the sides thereof. The perforated line 70 breaks upon the cover panel 44 being opened to form a horizontal, arcuate-shaped pouring edge. The cover edge panels 72 and 74 are secured to the side edge panels 40 and 42 effectively to control film delamination upon the cover panel 44 being opened. A side seam 26 is at a front corner of the container. Triangular segments 51 and 53, a side seam extension panel extension 92, and front panel extensions 94 and 96 have cut and thus uncoated edges 51', 53', 92', 94' and 96' which, in the closed condition, occupy positions stepped relative to each other. Widenings 84 to 90 of the cover edge panels 72 and 74 and the side edge panels 40 and 42 are sealed together inwards of the inner ends of the edges 51', 53', 92', 94' and 96'. <IMAGE></p> |
