The cardboard tray with a bottom and side walls (3,4) has a triangular section pillar (5) at each corner with one side biased relative to the walls. The biased side is formed by the superposition of two vertical rectangular tabs (7,8). The first vertical tab (7) joins one wall to an adjacent wall and the second vertical tab is narrower. The two opposite side walls (4) are connected by first folding lines to first end flaps and connected in the upper part by second folding lines to second flaps. These second end flaps are folded down inside the tray and fixed to the internal face of the corresponding side wall. Each first flap is connected by a third folding line to a third rectangular flap fixed on the face of the side wall adjacent to the first flap. The third flap is connected in bias and in the direction of the principal side wall direction to one of the first tabs by a fourth folding line. Each second flap is connected to one of the second tabs by a fifth folding line, the tabs being fixed together to form the corresponding corner pillars.
