摘要：
A carton has an openable bellows folded top comprising opposed side panels (30, 32) and front (34) and rear (28) panels folded in and sealed between the side panels. The panels are sealed together to close the top in a liquid tight manner. The top-forming front panel has an upper sub-panel comprising a central portion (44) having an upper free edge for defining the rim of a pull-out pouring spout and first and second flanking portions (46, 48) of unequal width lying each on a respective side of the central portion. The central portion is of a lesser height than the flanking portions and is not sealed on its interior face to the overlying side panels or to the rear panel in sealing the top. A reliable seal is formed but there is no obstacle to the pulling out of the pouring spout once the wing portions have been peeled apart.
