Abstract:
A paperboard packaging container for bulk solids includes a container body formed by a container wall having wall portions, and a container bottom. The wall portions are connected by corner portions and each wall portion extends in a height direction from a lower end edge at the container bottom to an upper end edge at a container opening, the height direction being perpendicular to a cross direction of the container. An upper reinforcing rim is applied to the container opening. Each of the upper and lower end edge of the container wall has end edge portions corresponding to the wall portions. At least one edge portion has an outwardly curved shape and a radius of curvature larger than a radius of curvature of each corner edge portion, the at least one end edge portion bulges outwardly with a radius of curvature of 200-700 mm, preferably 300-600 mm, more preferably 400-500 mm.
