Claim:
A self-mounting and collapsible tray obtainable from a stamped sheet, the tray comprising: a base ( 1 ), two side walls ( 2 ) and two end walls ( 3 ), the tray also comprising four corners in correspondence with which the side walls ( 2 ) are joined to the end walls ( 3 ), the tray comprising, in correspondence with each corner, a corner pillar formed from a side prolongation ( 4 ) of the corresponding end wall ( 3 ) of the tray, said side prolongation ( 4 ) of the end wall comprising at least four segments ( 41 - 44 ) separated by fold lines, of which at least one first segment ( 41 ) is affixed to the corresponding side wall ( 2 ), at least two intermediate segments ( 42 , 43 ) constitute a part of the corner pillar which extends between the side wall ( 2 ) and the end wall ( 3 ) of the tray in the erect position, and at least one last segment ( 44 ) is affixed to the end wall, so that, with the tray in the erect position, said intermediate segments ( 42 , 43 ) can be located in a first position in which the corner pillars lock the tray in its erect position, and a second position in which they allow the tray to be folded, the side walls and the end wall being folded toward the base ( 1 ); said last segment ( 44 ) is affixed to the end wall so that at least one part of the last segment extends from one of the intermediate segments ( 43 ) and toward a centre of the end wall, distancing itself from the corresponding corner of the tray, and in that wherein the tray also comprises, in correspondence with each end wall ( 3 ), a transversal flap ( 5 ) constituted by at least one part of a prolongation of the end of the end wall that corresponds to the upper part of the end wall of the tray in the erect position, said transversal flap ( 5 ) having two ends ( 51 ), each one folded over and affixed to an outside face of the corresponding side wall ( 2 ) wherein each of said transversal flaps ( 5 ) has, in correspondence with each corresponding corner pillar, a hole ( 52 ); wherein each corner pillar has, in correspondence with an upper edge of the intermediate segments ( 42 , 43 ), a prolongation ( 45 ) configured to extend through the corresponding hole ( 52 ), in the erect position of the tray; wherein the holes ( 52 ) of the transversal flap ( 5 ) and the prolongations ( 45 ) of the corner pillars are configured so that, with the tray in the erect position, the prolongations ( 45 ) are horizontally displaceable within the holes, so that by pressing on the prolongations ( 45 ) the intermediate segments ( 42 , 43 ) of the corner pillars can be displaced between the first position and the second position.
