Abstract

The invention relates to a packing container which is intended for liquid contents and is of the type which comprises a container body with at least one straight side wall (1) and an upper end wall (2) which is joined to the side wall (1) along a folding line (5) so as to form a relatively sharp transition between the package side (1) and the end wall (2). The upper end wall (2) is provided with a hole (4) penetrating the package wall which preferably is of triangular shape and which with one of its points reaches up to the lateral edge (5) between the upper end wall (2) of the package and its side wall (1). The hole (4) is covered from the inside by a thin plastic film, and from the hole (4) emanate two diverging perforation lines (6) which extend up to a common crease line (7) arranged in the upper end wall (2). Over the hole (4) and parts of the perforation lines (6) a further cover strip (8) with a thermoplastic coating is provided. The cover strip (8) is sealed to the inner plastic film exposed in the hole (4) and, at least in the region between the crease lines (6), to the upper end wall (2).
