The spout (1) has a sealable or shrink-wrappable connecting piece (3) attached to a sleeve (2) between two plastic edges, where the spout is made of plastic and a polypropylene injection moulding part. External-lateral seal surfaces taper to two end areas opposite to each other and are connected with each other at the edges that lie on or adjacent to the sleeve. Side walls of the connecting piece are provided with an uneven wall thickness that is increased to the open edges. The side walls are struted to the end areas by two transverse walls that are spaced from each other. |
