The invention relates to a folding rectangular parallelepiped box ( 1 ) which opens at the top. The box includes a base wall ( 3 ) and a rectangular upper frame ( 2 ), together with four side walls ( 4, 5 ), two facing walls, known as the first walls ( 5 ), articulated to the base ( 3 ) or frame ( 2 ) while the other two facing walls, called the second walls ( 4 ), include two leaves ( 40, 41 ) one of which is articulated to an axis (L<SUB>3</SUB>) parallel to the base ( 3 ), are also articulated both to the base ( 3 ) and to the frame ( 2 ). In one embodiment, this base ( 3 ) and the second walls ( 4 ) are a single folded sheet (F<SUB>2</SUB>), while the axes of articulation of the walls ( 4 ) to the base and to the frame ( 2 ), and of the leaves ( 40, 41 ) to one another, are in the form of fold lines (L<SUB>2</SUB>, L<SUB>3</SUB>, L<SUB>4</SUB>). The upper leaf ( 41 ) of the second walls ( 4 ) is extended by a reinforcing plate ( 42 ). This plate surrounds the frame ( 2 ) and is secured to the inner face of the upper leaf ( 41 ), in such a way that when the box is in the erect position, this plate ( 42 ) presses against the associated second wall ( 4 ), while in the folded position the lower part ( 420 ) of this plate ( 42 ) is detached from the second wall ( 4 ) and forms an inverted "Y" therewith.
