摘要

The present invention relates to a device at packages, coupling members and method for application of a coupling member. The device comprises coupling members ( 4, 8 ) with non-circular coupling portions ( 5, 9 ) which fit together only if they have the same non-circular shape. The non-circular coupling portions ( 5, 9 ) are also located relative to the package ( 1 ) such that a conduit ( 13 ) for discharging product ( 3 ) from the package ( 1 ) attains a predetermined position in relation thereto or the conduit ( 13 ) can be rotated to such a position.
