Abstract:
Set (1, 32, 37, 43, 48, 52, 58, 69, 72, 78, 91, 110) of blanks for constructing a packaging box, comprising at least two blanks made of a material in the form of sheets of board or corrugated board, namely a first blank (2, 48, 59, 81, 126, 140) comprising a series of at least four principal leaves (4; 85, 86, 87, 86') ending in a fixing tab (15, 15"", 61), said principal leaves and said tab being connected to each other via first fold lines (5) parallel to each other, directly or via intermediate leaves, which series is provided on one side with a first series (6, 82) of flaps connected to said series of principal leaves by second fold lines (7) perpendicular to said first fold lines, said series of leaves being able to form a ring of walls for the box and a second blank (3, 24, 33, 38, 38', 44, 49, 53, 63, 73, 79, 92, 111, 127, 141) comprising at least two panels (10, 11, 12, 13; 25, 26; 39, 40, 41; 45, 46, 47; 49; 55, 56; 64, 65, 66, 67, 68; 74, 75, 76; 94, 96, 97; 112, 114, 116, 117, 118, 119) connected together by a third fold line (14, 74', 95, 113), namely a first panel and one or more second panels, characterizedin that the second blank overlaps at least one fold line of the first blank,in that the first panel is fixed and/or centered on the first blank,in that said second panel or at least one of said second panels is fixed to said first blank by means (83, 83', 84, 84', 88, 89) arranged so as to permit relative movement of said second panel or panels with respect to the first blank when the box is being formed by a simultaneous rolling up of said prejoined blanks around a volume (161) of defined dimensions, andin that the third fold line or lines (14, 74', 95, 113) of the second blank are laid out and positioned with respect to the corresponding fold lines of the first blank in order to enable the extra thicknesses of the sheets of board to be compensated for during said rolling up.
