Abstract
Opening arrangements for packing containers of the type which comprise a tearing or pulling device applied to the outside of the packing container are known. By means of the pulling device a part of the wall material of the packing container can be removed so that a pouring opening is generated. To prevent the packing laminate from delaminating on opening, so that only the outer layer accompanies the pulling device, it is proposed in accordance with the invention to design the opening part so that a penetrating part is first thrust downwards through the laminate, whereupon the opening part with the pentrating part and the underlying, breached part of the packing laminate is lifted upwards so that a pouring opening is generated.
