发明名称 Packing container provided with opening arrangement
摘要 A packing container (1) is provided with an opening arrangement comprising a pair of spaced lines of tearing perforations (8a, 8b) arranged in a wall portion of the container, the braking up of which causes the wall material between the perforations to be displaced so as to form a corresponding emptying opening when the container is opened. A hole (9) is provided extending through at least a portion of the thickness of the wall, e.g. through a central paper layer between two plastics layers, and connecting the spaced lines. An adjacent area of the wall bordering the hole is formed as a tongue (10), and a cover strip (11) being provided sealing over the hole.
