ABSTRACT:
The invention relates to an opening arrangement on parallelepipedic packing containers of the type which include a sealing fin extending over the top end wall of the packing container and a longitudinal overlap joint which crosses the sealing fin. In the region of the sealing fin arranged between a crossing point and a tip of a triangular lug, which is connected with the top end wall of the packing container, a strip is provided which includes a central portion of a non-extensible or only slightly extensible, material and outer coverings of thermoplastic. These outer coverings, upon sealing of the fin, will fuse together with an inner plastic covering of the packing material in the fin. The packing container is adapted to be opened by upwardly pulling a part of the strip projecting at the crossing point, so that the central layer of the strip is detached from the outer coverings to form an emptying channel.
