Claim:
A set of blanks for making a packaging box, comprising two blanks made of a corrugated cardboard sheet material, namely: a first blank comprising a first series of at least four main flaps terminated by a fastening tab, connected together by first fold lines parallel with one another and, having on a first side, a first series of folding elements connected to said first series of at least four main flaps by second fold lines perpendicular to said first fold lines, said first series of at least four main flaps being adapted to form walls of a base of the packaging box, and a second blank comprising a second series of at least three panels connected together by third fold lines parallel with one another and having a second series of folding elements connected to said second series of at least three panels by fourth fold lines, said second blank being suitable for forming a lid of said box, wherein: the at least four main flaps of the first series of at least four main flaps respectively comprise: a first rectangular flap designed to form a back wall of the base, having on a second side the first series of folding elements with a tear-off folding element connected to said first rectangular flap by a perforated junction line, and two nonadjacent trapezoidal flaps designed to form side walls of the base, each comprising an inner edge directed at least partly slantwise toward a central flap of reduced height as compared to said two nonadjacent trapezoidal flaps and designed to form a front face wall of the base, the at least three panels of the second series of at least three panels respectively comprise one rectangular central panel and two trapezoidal side panels comprising an outer edge directed at least partly slantwise in the direction of the second series of folding elements and in directions parallel to facing inner edges of the two non-adjacent trapezoidal flaps when the third fold lines of the second blank are in line or substantially in line with the first fold lines of the first blank, and the two blanks are arranged to allow a sufficient overlap to allow one to be bonded to the other at facing inner and outer edges of trapezoidal flaps and panels when the perforated junction line and the fourth fold lines are in line or substantially in line.
