摘要

Improvements in the construction of folding boxes with at least four closing flaps superimposable and at least partially gluing together a cut that contains the four side walls and with a manifold exit closure repeatedly obturable, characterized by that for the formation of a sliding closure of at least two of the overlapping flaps, in each case show an opening that is covered, and that between these flaps is arranged one of the other side flaps, showing a notch in its width at least equal or greater than the width of the openings, with a length greater than the openings, in which a tongue-like slide engages from the outside longitudinally as a closure of the openings.
