A packing container for liquid contents manufactured of a packing material of plastic-coated cardboard and which comprises:

• a container body with an inside and at least one straight side wall and an upper end wall which is joined to the side wall along a folding line so as to form a relatively sharp transition between the package side wall and the upper end wall;
• a hole arranged in the upper end wall, which hole extends up to the folding line;
• two weakening lines which extend from opposite edges of the hole in divergent directions over the upper end wall of the packing container up to a crease line in the upper end wall;
• the hole being covered from the inside of the package by a thin thermoplastic film which constitutes the inner plastic coating of the packing material;
• a cover strip arranged over the hole and at least over parts of the upper end wall between the weakening lines and which cover strip is sealed to the thermoplastic film exposed in the hole and to the outside of the upper end wall between the weakening lines;
• wherein the crease line in the upper end wall is of a curved shape with a convex side facing towards a region between the weakening lines.
