A cardboard case-box container (S) eventually associable to a cover, in which the cardboard is preferably impregnated with sealing material to be impermeable for liquid materials and in which for the preparation of the case-box (S) we use a substantially rectangular diecutting cardboard correspondent to the development perimeter of the case-box or greater, with prefold lines (p) to form: a squared bottom (1) and four squared side walls (2, 3, 4, 5), where the respective external quadrangles between them (6), present three prefold lines in bellows-bendings, by means of bending them externally on two opposed side walls (2, 4) of the case-box, which bent bellows-bendings will be laced by means of respective prolongations (8, 8') of said sidewalls (2, 4), characterized in that the end of said prolongations (8') have the dovetail shape to be in turning-up bent under the edge of tilted bendings of said bent bellows-bendings (b), to be set in 180 DEG inside-turning up upright position, between the couple of said bellows-bendings (6, 6', 6'', 6''') and the respective underlying lateral wall (2 on one side and 4 on the other). |
