Abstract (en)
[origin: WO2017055680A1] The invention relates to a blank for a leakproof and liquid-tight packaging box and to the packaging box formed from it. The blank is one-piece and comprises a base surface (1 ), the folding surfaces (2) of the long sides of the box, the vertical surfaces (3) of the short side, a first corner bellows (6) and a second corner bellows (7) of the corner structure and the inclined fold (18) between them. What is essential in the invention is that the packaging box blank comprises a conical fold (21 ) between the folding surfaces (2) of the long sides of the box and the second corner bellows (7) in such a way that the folding line is inclined with respect to the crease (22) between the base surface (1 ) and the vertical surface (3).
