Abstract (en)
[origin: EP0941947A1] The container (1) has at least one preferably rectangular flap (2), which pivots about a rotation axis (3) to seal a container discharge opening. At least a first narrow side wall (5) of the flap that is near to or parallel to the rotation axis has at least a part of its cross-section inclined from the front surface of the flap at an angle that is not 90 degrees . The opening side wall is inclined in the opposite sense so that these two angled surfaces fit together and at least partly lie parallel. The narrow side wall of the flap forms an obtuse angle with the outer surface (8) of the flap. As the flap is opened or closed its narrow side wall follows a path (9) in which it gets closer to the flap rotation axis. The oppositely inclined opening side wall surface forms an acute angle with the outside (10) of the container.
