Abstract
The invention relates to a set (22) of blanks for forming a packaging box, a method and a corresponding box. The set includes two corrugated board blanks, namely: a first blank (2′) including flaps connected to one another by first fold lines (9′), one side of said blank having no folds; and a second blank (12′) including panels (13′, 14′, 15′, 16′) connected to one another by third fold lines (19′), the panels of the second blank being stacked respectively on the part of the first blank having no folds. Two non-adjacent flaps (3′, 5′) of the first blank are glued to two respective facing panels (13′, 15′) of the second blank, thereby preventing the relative movement thereof during folding or during the formation of the box when the blanks are wound around a volume having pre-determined dimensions. At least two-thirds of the third fold lines (19′) of the second blank are substantially aligned in relation to the first fold lines of the first blank, the lower part (23) of one or more of said third lines including a cut or collapsed portion opposite the corresponding first fold line.
