<p>The drawings and description disclose a container having the usual fold-in end panels and roof panels (40, 42) interconnected by front and rear sets of fold-back panels (62, 64, 82, 84), with inner sealing rib panels (70, 72) extending vertically from the fold-back panels and confined between oppositely disposed outer sealing rib panels (60, 54) extending vertically from the roof panels, supplemented by fold-over lip panels (76, 78) attached to and folded over onto the inner sealing rib panels, serving to provide a stiffer spout to facilitate the opening process, while eliminating a raw edge on the pouring lip and greatly diminishing fiber tear and delamination of the pouring surface. </p> |
