Each of the first to third strip-shaped panels is connected, and each of the first to third top wall panels has a long side with a length equal to the length of the horizontal score line and a length half the length of the horizontal score line. The first top wall panel has a rectangular shape with a short side having a width, and two inclined score lines extending from both ends of the horizontal score line at an angle of 60 degrees to the horizontal score line are formed on the first top wall panel. is divided into two isosceles trapezoidal panels on the inside of the two oblique score lines and two right triangular panels on the outside thereof, with the second and third top wall panels having the first top wall panel of the transverse score lines. A first sloped score line extends from one end adjacent to the horizontal score line at an angle of 60 degrees to the horizontal score line, and a first slope score line extends from the other end of the horizontal score line at an angle of 30 degrees to the horizontal score line at the upper end. A second slope score line intersects with the upper end of the slope score line, and a third slope score line extends from the other end of the horizontal score line at an angle of 60 degrees with respect to the horizontal score line. The three top wall panels include a large right triangle panel inside the first and second slope score lines, an isosceles triangle panel between the second and third slope score lines, and a first and third slope score line. two small right triangular panels on the outside of each of
~The third strip panel is folded in half with the two vertical score lines as boundaries, and their opposing inner surfaces are joined together, so that the first to third strip panels form a seal, and the isosceles trapezoidal panel is folded horizontally. Inwardly along the score line, the large right triangle panel outwards along the horizontal score line, the isosceles triangle panel inwardly along the second slope score line, and the minor right triangle panel outwards along the first slope score line. The isosceles trapezoid panel and the two adjacent small right triangular panels of the second and third top wall panels are each folded inwardly along a line so that the isosceles trapezoidal panel and the two adjacent small right triangular panels of the second and third top wall panels form the top wall, the right triangular panel of the first top wall panel, and the second The large right triangular panel, the isosceles triangular panel, and the remaining small right triangular panels of the third top wall panel are made into a triangular flap, and the seal portion is bent so as to overlap the top wall and both triangular flaps, and both triangular flaps are folded. are bent and fixed to the second and third side wall panels together with a portion of the seal portion thereon so as to be overlapped with the second and third side wall panels.
