ABSTRACT:
Packing containers with fold-out pouring spout are used for a great number of beverages, e.g. milk. The pouring spout comprises a number of connected triangular wall panels which are delimited by folding lines. On opening, the pouring spout is folded out and the packing container is opened in that an outer end of the pouring spout is removed. To prevent the pouring spout from reverting to its folded-in condition after opening, the folding lines which delimit the material panel of the pouring spout from the upper side of the packing container are arranged so that they run at unequal angles. In this manner the breaking open and the forming of the pouring spout are facilitated.
