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 6 which also serves as a closure for a pouring opening 7. In order to prevent the pouring edge strip 8 from being torn off or deformed at the removal of the cover strip 6, 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. |
