PROBLEM TO BE SOLVED: To provide an assembly box that allows, when opening the box's lid formed of bonded upper and lower flaps, the bonded upper and lower flaps to be easily opened with a little force without damaging them, the assembly box being such as a corrugated cardboard box being made of a thick paper such as a corrugated cardboard paper, with its upper aperture being constituted of four pieces of upper and lower flaps in communication with the side walls, forming the box's lid by bonding with adhesive and sealing both the flaps places opposite to each other when the upper flaps and the lower flaps are bent. SOLUTION: The assembly box made of corrugated cardboard, etc., is characterized in that peel-off incisions for break-opening the seal are provided on the upper flaps with the adhesive-applied portions on both the right and left sides of the upper flaps being made the peel-off parts for opening the seal, while non-adhesive-applied portions are demarcated as seal-opening parts. When opening the box, the seal-opening parts, that is, the non-adhesive-applied portion of the upper flaps are pulled up (lifted up) for opening the seal, thereby breaking the peel-off incisions for break-opening the seal, causing the upper flap's peel-off parts bonded with the lower flaps and the seal-opening parts to be separated, thus securing easy opening of the seal with a little force.
