摘要

The board (1) has a strap (3) sealed along an edge of an upper open container. The board is opened along an intermediate layer during opening the strap. An inner multi-layered film is firmly and durably sealed at the container edge. A plastic part is provided with circumferential weakening lines (5', 5'') that release openings (5) during peeling off of an upper multi-layered film. Other weakening lines (4, 4') are provided in an aluminum part, act on a side of the strap from a periphery of the board and run narrowly adjacent to the former lines in an area of the openings.
