This invention relates to a tray or box to be made from a blank by folding and adhesion, comprising a bottom wall (1) and upright walls (6-9) connected thereto by folding lines (2-5), wherein at the corners where upright walls (6-9) meet, one of said walls (8,9) is extended by means of a rectangular connecting flap (13) hingedly connected thereto and in the other upright wall (6,7) a triangular connecting zone (11) is bounded by a folding line (10) inclined at 45°, which connecting zone after being folded back against the rear side of the upright wall (6,7) is attached by adhesion to said rectangular connecting flap (13) and wherein at least a number of the upright box walls (8,9) are provided with so-called overlap panels (15) which are folded over against the corresponding wall panels (8,9) along a folding line (14) and are adhesively affixed thereto, characterized in that at least one of the overlap panels (15) is connected via a folding line (19) to a bottom-doubling panel (20). At opposite side edges of bottom-doubling panels (20), suspension flaps (22) connected thereto along folding lines (21), may be provided, which are adhered to the upright sidewalls (6,7) with the triangular connecting zones (11).
