1. A tray made from cardboard sheet material comprising a rectangular base and an enclosure of two first opposite lateral first walls, which are symmetrical relative to a transverse axis of the tray, and are each provided respectively with at least one reinforcement element which forms a pillar, and second front and rear walls, the front second wall having a shorter height than the other walls, each of the walls being formed by a double panel obtained by edge folding an inner flap on an outer flap, wherein the outer flap of the second rear wall is connected to the base by a first folding line, and is connected to the outer flaps of the two first walls by second folding lines perpendicular to the first folding lines, the inner flaps of said first walls are connected to said outer flaps, respectively, by a third, double folding line, and the inner flaps of the second walls are connected to the corresponding outer flaps by fourth double folding lines, the respective inner flaps having the same dimensions, or substantially the same dimensions, as the respective outer flaps, their free peripheries opposite said fourth double folding lines being blocked by friction and/or by snapping of lugs together with the upper face and/or corresponding recesses in the base of the tray, wherein the inner flaps of the first walls each comprise a rectangular central panel with a length l which is smaller than the width L of the base, said panel being connected at one of its lateral ends by a fifth folding line to the reinforcement element which forms a pillar provided with a first turned-down piece cooperating with the inner face of the outer flap of the second front wall, said reinforcement element being folded back and blocked relative to said central panel by a second turned-down piece connected to the outer flap of the first wall by a sixth double folding line situated on the side opposite the second folding lines. 2. The tray as claimed in claim 1, wherein the reinforcement element is formed by three vertical tongues which are connected to one another by seventh folding lines, the two first tongues forming said pillar, and the third, end tongue being blocked by snapping of a blocking lug which is integral with the corresponding second turned-down piece into a recess along the seventh folding line when it is opposite. 3. The tray as claimed in claim 1, wherein the side of the outer flap of the first walls comprising the sixth folding line is aslant relative to the vertical on its upper part along said sixth line, and comprises in its lower part a third turned-down piece which is designed to cooperate with the inner face of the corresponding first turned-down piece, the fourth folding line of the second front wall being double. 4. The tray as claimed in claim 1, wherein, on the side opposite the third folding lines, and connected by an eighth folding line, each outer flap of a first wall comprises a lower flap which is folded back onto the upper face of the base of the tray, in order to form a half double base on the tray. 5. The tray as claimed in claim 4, wherein the two lower flaps forming half double bases comprise means for locking of one with the other. 6. The tray as claimed in claim 1, wherein the third folding lines and fourth folding line of the second rear wall comprise tenons which are cut out from said third and fourth lines, protruding relative to the corresponding inner flaps, and the base of the tray comprises recesses with a complementary form arranged level with said tenons, for embedding of the tenons of a tray below. 7. A blank for constitution of a tray, comprising a rectangular base and an enclosure two opposite lateral first walls, which are symmetrical relative to a transverse axis of the tray, and front and rear second walls, the front second wall having a shorter height than the other walls, each of the walls being formed by an inner flap and an outer flap, wherein the outer flap of the second rear wall is connected to the base by a first folding line, and is connected to the outer flaps of the two first walls by second folding lines perpendicular to the first folding line, the inner flaps of said first walls are connected to said outer flaps, respectively, by a third, double folding line, and the inner flaps of the second walls are connected to the corresponding outer flaps by fourth double folding lines, the respective inner flaps having the same dimensions, or substantially the same dimensions, as the respective outer flaps, wherein the inner flaps of the first walls each comprise a rectangular central panel with a length l which is smaller than the width L of the base, said panel being connected at one of its lateral ends by a fifth folding line to a reinforcement element which forms a pillar when the tray is formed, provided with a first turned-down piece, designed to cooperate with the inner face of the outer flap of the second front wall when the tray is formed, said reinforcement element being designed to be folded back and blocked relative to said central panel by a second turned-down piece connected to the outer flap of the first wall by a sixth double folding line situated on the side opposite the second folding lines. 8. The blank as claimed in claim 7, wherein the reinforcement element is formed by three vertical tongues which are connected to one another by seventh folding lines, the two first tongues forming said pillar, and the third, end tongue being designed to be blocked by snapping of a blocking lug which is integral with the second turned-down piece into a recess along the seventh folding line when it is opposite. 9. The blank as claimed in claim 7, wherein each outer flap of a first wall comprises, on the side opposite the third folding lines, and connected by an eighth folding line, a lower flap which is designed to be folded back onto the upper face of the base of the tray, in order to form a half double base on the tray. 10. The blank as claimed in claim 7, wherein the side of the outer flap of the first walls comprising the sixth folding line is aslant on its upper part along said sixth folding line, and comprises in its lower part a third turned-down piece which is designed to cooperate with the inner face of the corresponding first turned-down piece, the fourth folding line of the second front wall being double.
