Improvements in the manufacture of boxes for packaging, characterized by the fact that the boxes are constituted by a sheet of semi-rigid material, such as corrugated cardboard, obtained by die-cutting and with the making of some folds, presenting the four sides of its lateral contour and an end flange to overlap the opposing end edge, for the closure of said contour, by means such as stapling, gluing and sewing, so that from each pair of opposite faces there extend wings, each of which passes to forming a half cover for the upper and lower faces of the box, introducing a front marginal portion in the middle line of the box, while from the two remaining opposite faces there are derived fins, optionally centrally notched, which are applied in a manner of internal backstops and introducing in the box their marginal leading edges between the first and second rows of compartments to be formed, sde each side, whose compartments are obtained with the possible collaboration of separating pieces that complement the aforementioned wings and fins to complete the divisions, the different pieces being intersected by means of notches.
