The pouring spout is formed in one of the corners (5) defined at the ends of the transverse seals (3, 4) by means of a semi-rigid insert (6) arranged on the container wall in such a way that it is flush with said seal (3) and straddles both sides of said corner (5). The insert includes one portion (BV) for forming a pouring spout and another portion (AM) forming an extension of the spout portion (BV) and providing a supporting and stiffening strip for the spout when it is resiliently deformed by a pressure (P) exerted on the hinge portion (19) between said portions (BV, AM).
