ABSTRACT:
An opening arrangement for packing containers comprising a prepunched opening which is covered by a tear-off cover strip and a pouring rim element positioned between a wall of the packing container and the cover strip. In one of the embodiments, the pouring rim strip has an edge portion which projected partially over the opening of the packing container and a liquid-tight layer is joined to both an inside surface of the packing container wall and the edge portion of the pouring rim strip, as well as to a portion of the cover strip positioned over the opening. The application of the pouring rim as well as the manufacture of the opening arrangement as a whole are facilitated by joining in advance the pouring rim in a detachable manner to the cover strip, so the cover strip and the pouring rim can be applied as a unit.
