Abstract

A mouth device for cardboard boxes, of the type composed of four fins, two larger ones that give prolongation to the sides of the box and two smaller ones that extend the end walls, characterized in that the larger fins have two lines of longitudinal fold that define three sectors of greater fin of different width, the fold line being closer to the free longitudinal edge of the fin provided at its ends with respective rectangular cuts that reach the transverse edges of the same fin; the central area of the intermediate fin section being provided with a draft for the handle and each fin section being provided with cuts or openings in transverse alignment near the transverse edges of the major fin itself; and because the smaller fins have a fold line that defines two sectors of smaller fin, the upper one of which is an acute angle whose bisector is a cut with inner flanges that defines two wings with external central flanges, the ends of the box being provided with cuts or openings in the base of said lower fins, so that closing the mouth of the box occurs by folding the fold line of each major fin closest to the free edge of the latter, to juxtapose the end sector over the intermediate sector of each fin; placing the juxtaposed sectors of each major fin side by side and projecting them towards the bottom of the box so that the ends of said sectors are inserted in the grooves of the front ends and folding the smaller fins so that the attached sectors of the greater fin they are housed in the bisecting cut that defines the wings of the smaller fin, and the flanges of said wings penetrate into those in transverse alignment provided by the box.
