发明名称 PACKING CONTAINER LOCK
摘要 An opening arrangement on a packing container (1) comprising a hole (4) provided in the wall (3) of the container which is covered from above by a flexible strip (6) applied to the outside of the container. The strip has at its one end (6a) an openable portion (9) situated within the hole region which is adapted so as to be torn off to expose a corresponding pouring opening by bending backwards the other end (6b) of the strip, which in unopened position is bent over the hole (4) and is sealed to the underlying portion 9. To retain the strip (6) against the outside of the container, and to prevent contact between the cut edge of the hole (4) and the contents of the container, the strip has a projection (7) directed downwards, accomodated in the hole, whose free end (7a) is folded over round the cut edge and is sealed to the inside of the container wall in a liquid-tight and mechanically strong sealing joint round the whole opening contour of the hole.
