ABSTRACT Pouring edges in the form of projecting material strips are used on packing containers for e.g. liquid foodstuffs. The pouring edge is generally covered by a tear-off cover strip which also serves as a closure for a pouring opening . In order to prevent the pouring edge strip from being torn off or deformed at the removal of the cover strip , the same is given a z-folded form and is joined to the outside of the packing container in two sealing areas situated at a distance from each other, the doubled area located in between projecting from the packing container and guiding the out-flowing liquid.
