Zusammenfassung:A packaging container capable of reducing a tensile or compressive stress in the paper container caused by folding the pleat portion thereof to maintain the strength characteristics thereof, and providing a wide roof portion on one side thereof so that a large-sized spout can be fitted thereto. The packaging container including a pouring spout fitted thereto is characterized in that the top part thereof formed by folding the pleat line is formed of a surface tilted forward on the front side of the top part and a substantially flat surface adjacent to the tilted surface on the rear side of the top part and that a flap derived from the formation of the top part is allowed to abut on the container side-walls adjacent to the top part by the folding of the pleat.
