<p>The invention relates to an arrangement on parallelepipedic packing containers (1) of the type which comprises a sealing fin (4) extending over the top end wall (3) of the packing container (1), this packing container (1) comprising moreover a longitudinal overlap joint (2) which in the region (6) crosses the sealing fin (4). in the region of the sealing fin (4) which is arranged between the crossing point (6) and the tip (15) of a triangular lug (5), which is connected with the top end wall (3) of the packing container, a strip (10) is provided which consists of a central part of a non-extensible, or only slightly extensible, material and outer coverings of thermoplastic which, on sealing of the fin (4), will fuse together with the inner plastic covering (14) of the packing material in the fin (4). The packing container (1) is adapted to be opened by pulling upwards a part (9) of the strip projecting at the crossing point (6), so that the central layer of the strip (10) is detached from the outer coverings (11) and an emptying channel (13) is formed.</p> |
