Disclosed is a plastic moulded box with parallelepiped structure and rectangular base provided with collapsible lateral walls (3, 4, 5), in which the two longitudinal walls (3, 4) are higher than half of the width of the transversal walls (5). The two longitudinal walls are perfectly aligned on the same horizontal plane when they are collapsed in idle position by means of partial male-female coupling.
