Cardboard packaging has cover central part hinged at each end of body wall, and when wall is in position locking element overlaps contiguous wall

摘要

At each end of the body wall (26) the central part (27) of the cover (22) is hinged by a folding line. Perpendicular to the bottom a locking element when this wall is in position overlaps the contiguous wall (24), with a part (31) applied against its external surface and another part (33) applied against its internal surface. These two parts are hinged by a folding line and supported on the edge of the contiguous wall.
