The drawings and description disclose a container having the usual fold-in end panels and roof panels interconnected by front and rear sets of fold-back panels, with inner sealing rib panels extending vertically from the fold-back panels and confined between oppositely disposed outer sealing rib panels extending vertically from the roof panels, supplemented by fold-over lip panels 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.
