Abstract
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.
