Folding box, of the type that is obtained from a single sheet provided with fold lines, characterized essentially by the fact that in said sheet a bottom is defined from which the laterally opposite longitudinal walls are erected which have at their ends each rectangular fins whose dimensions are equivalent to respective halves of the end walls which are raised from said bottom, which fins are disposed towards the inside of the box in a position normal to the longitudinal walls and such fins overlap the end walls which are provided with so many transverse end flanges that are inserted in incisions formed in end zones between the upper edge of the longitudinal walls and two wings respectively articulated by bending to such walls, 1 whose flanges are endowed at their extremities. As many tongues that are attached externally to the long walls these ends are introduced into respective windows of said walls and are bent, applying them to the internal face of these walls, whereby the four walls of the box in which the ends of the wings of the walls of the box are held in a raised position are held together. The longitudinal walls are applied on the aforementioned flanges, with which the box is closed and it helps to retain the four walls together.
