Substantially parallelepipedic packaging and gable-top containers for liquid contents, for example milk, are manufactured by folding and sealing of laminated packaging material and include two substantially planar end portions, as well as four vertical wall panels. The volume of the packaging container may be increased in relation to the area of the packaging material employed in that the vertical wall panels, the primary wall panels, are supplemented with secondary wall panels which are defined by straight, vertical fold lines which, at the upper and lower ends of the panels, respectively, merge into pairwise converging diagonal fold lines which intersect at a point. In a blank for the packaging containers, the wall panels are defined throughout the greater part of their length, by straight, parallel, vertical fold lines.
A packaging container for liquid products comprising a plurality of side wall panels and a top portion and a bottom portion, the side wall panels extending between the top portion and the bottom portion and including secondary wall panels, each secondary side wall panel being defined by a pair of vertical fold lines having their ends spaced from the respective top portion and bottom portion and by a pair of diagonal fold lines extending from the ends of the vertical fold lines and converging toward the top portion and the bottom portion respectively, said top portion and bottoms portion forming liquid-tight seals including at least one of said top and bottom portions having a transverse sealing fin.
A blank for packaging containers for liquids, said blank comprising a packaging laminate having upper and lower horizontal fold lines corresponding to the top and bottom of the container and having primary side wall panels, and having a plurality of secondary side wall panels, the secondary side wall panels being defined by pairs of parallel vertical fold lines having their ends spaced from the upper and lower horizontal fold lines, and the secondary side wall panels being interposed between the primary side wall panels, said blank being adapted to form a substantially liquid-tight container including a transverse sealing fin.
