Method for producing two boxes for small sheets from a box for large sheets, characterised in that, in each of the two bases of the large box, a rectangular sheet is cut out, whose large side has a length equal to the half-length of the large box increased by four times the depth of the latter and whose small side has a length substantially equal to the half-width of the large box increased by four times the depth of the latter, then, by successive folding operations, each of the said rectangular sheets is used to form a small box, finally, using two sheets each having a large side with a length substantially equal to the half-length of the large box increased by twice the depth of the latter and a small side with a length substantially equal to the half-length of the large box, a small box is formed from each of the said sheets. |
