Abstract (en)
[origin: EP0392624A1] Collapsible tray and tray cover formed from a blank and each comprising a bottom wall (1; 2), upright walls (7-10; 22-24) connected to said bottom wall along fold lines (4, 5; 19-21), where in each corner of said bottom wall the adjacent upright walls are interconnected by a rectangular connecting flap (14; 28) and a substantially isoceles-triangular connecting area (12; 26) bounded by a substantially 45 DEG fold line (11; 25) in the other wall meeting at said corner. Said connecting flap (14; 28) and said connecting area (12; 26) are mutually fastened by the use of adhesive after folding back the connecting area against the rear side of the relevant upright wall, so that in the collapsed state of the box, the upright walls are foleded down on top of the bottom wall with the triangular connecting areas (12; 26) and the connecting flaps (14; 28) located between adjacent upright wall panels. The invention provides such a ready-for-use collapsible box, a two-part pulling element (32, 38), the two parts of which being interconnected by a fold line (37), said pulling element being arranged at one of the fold lines connecting for example cover walls (2; 22, 23), such that, while its parts (37, 38) are attached to the said cover walls (2; 22, 23), the fold line (37) of the pulling element is parallel to the cover fold line (19, 20) and off-set in relation to the cover fold line (19, 20) towards the middle of the cover bottom wall (2). The effect of the pulling element (32, 38) so arranged is that in the position of use and the tray closed by the cover, the upright cover wall (22, 23) is pulled inside against the adjacent upright wall (7, 8) of the tray, preventing this tray wall from flexing outwards under vertical load.
