<p>A ready-to-use box comprising a bottom panel (1) and upright longitudinal (2) and transverse walls (3) connected thereto by fold lines (4,5). Owing to the specific corner connection, the upright walls can be collapsed onto the bottom of the box. At each corner, where two walls meet, one of the walls (2) is provided with a reinforced end part of multiple wall thickness, either of flat construction or of Y or "butterfly" construction, terminating at a short distance from the adjacent upright wall. In the erected box, at each corner, a vertical support panel (20) extends obliquely between the upright walls (2, 3) along the free end edge of the reinforced wall end part. Cooperating locking means (23, 24) at the reinforced wall end part and at the vertical support panel (20) fix the reinforced wall end part at a slight angle relative to the plane of that wall part (2) in the direction of the adjacent upright wall (3). <IMAGE></p> |
