METHOD FOR FORMING A CORNER JOIN AT A CORNER OF A BOX, METHOD FOR MAKING A SOLID BOARD BLANK PERMEABLE TO AIR, BOX OBTAINED USING ONE OR BOTH METHODS, ASSEMBLY OF A BOX AND FILLING, THE USE OF A BOX AND A BOX BLANK

摘要

A corner join in a box is formed from a blank having a base section (2) and two side wall panels (4, 6) each joined thereto via a fold line (3, 5). A joining flap (15) is joined to one of the side wall panels (6) via a fold line (7). The fold line of the joining flap (15) essentially defines the corner, and the point of intersection of the three fold lines (3, 5, 7) is located in the base panel approximately at the corner. The side wall panels are joined to one another by placing the joining flap in contact with the second side wall panel (4) such that it overlaps the later in an overlap area, and fixing it to the side wall panel. A mastic-like filler (204; FA) is applied in or on the inside of the panel fold line (3) to which the fixing flap (15) is fixed at the location of the overlap area with the fixing flap (15). The invention further relates to a box and blank made of solid board which has been coated on one or both sides with a coating that is essentially impermeable to gas and has been provided with air passages through the coating, and to a method for making the air passages.
