A carrier section (2) is captively integrated into a box which is stabilized in a folding and glueing operation, said box comprising four side walls (5, 5, 6, 6) connected approximately at right angles to a base section (4). One of the side walls is embodied in the form of an articulated strip (7), at least as far as part of the length thereof is concerned. Said strip can be pivoted on the plane of the base section (4) and is coupled to the carrier section (2).
