Abstract

Armored box, with self-fastening covers, which is obtained starting from a cardboard sheet on which, through cuts and slits, the bottom is achieved, the end walls with their extreme extensions forming the triangular columns of reinforcement and the extension of the edge upper formativa of a back of the front, as well as the lateral ones with their prolongations of the upper edge acting as semitapas, and it is characterized essentially because as much the flap that forms the back of the front as the acting ones like semitapas solidary of the lateral ones have practiced, at least, a cut parallel to the split line for its bending, at a height slightly above said fold line, and in whose cutting or cutting zone said crease line has been suppressed, in such a way that limiting the cut by other cuts transverse small rigid vertical fins are established which, by folding the flaps along the crease lines, cause the cut edge of said flaps jump over the rigid pad preventing the backward movement to its initial position of the flaps, whereby the flaps, both the spine and the half-tabs, are automatically in the closed position.
