Abstract

A folding box, of the type that is constituted from a flat development punched out of semirigid laminar material, which forms a bottom and four lateral walls articulated by corresponding fold lines to the edges thereof and arranged to be folded orthogonally with respect to the same, characterized in that the junction between each two adjacent side walls is made by means of a flap articulated to the side edge of one of them, which is reframed and applied to the other, an articulated cover having been provided in one of the indicated side walls, in the two walls adjacent to that respective inclined bending lines that divide them into two zones susceptible to being refracted one over another, and in the fourth wall two inclined folding lines, symmetrical, which determine three articulated zones that can be folded over one another; with the characteristic that the indicated flaps: are fixed to the corresponding side walls, only to the part of these walls that is located on the said fold lines, so as to allow the free play of the articulation signified by these lines from a limit position of assembly, up to a limit position in which all of the side walls are folded on the bottom; and with the feature, in addition, that the aforementioned cover has on its free edges a system of ridges arranged to fit on the side walls, which are mounted by analogous system and can be retracted on the cover by arranging the same lines inclined bends.
