The cardboard is configured from a die-cut base sheet having side and front walls with side flaps. It comprises both reinforcement front walls (5) which are independent from the base sheet (1), and which are backed to the side walls. The reinforcement front walls (5) are comprised of a central sheet (6) divided at its sides by three folding lines which define an inner sector (7), an outer sector (8) and a flap (9). The inner sector (7) and the outer sector (8) configure in the trussing of the reinforcement front walll (5) a prismatic portion which provides for the resistance to stacking. Supports or reinforcement columns (19) are optionally provided, which match in length with the height of the cavities (20) of the prismatic portions.
