The bent side 5 is overlapped from the inside with the end of the rising piece 4 on the other side, that is, the short side, and is bound by the stitch needle 6. Further, the tip end of the bent piece 5 is cut out so that the upper side portion 7 is left, so that when the bent piece 5 is bound to the end of the rising piece 4, the rising piece 4 is cut. The fitting recess 8 is formed together with the end portion. A triangular engagement hole 9 is formed in the bottom plate 2 of the bottom box 1 near the center of the rising piece 3. Reference numeral 10 denotes a pair of elongated lower cushioning members made of styrofoam, and a mounting projection 11 is formed on an upper portion of an end portion thereof so as to project laterally, and the fitting portion is formed on a lower portion of the end portion. A rectangular fitting protrusion 12 corresponding to the mating recess 8 is formed so as to project in the lateral direction, so that the bent piece is provided between the mounting protrusion 11 and the fitting protrusion 12 at the end thereof. A fitting recess 13 having a substantially inverted L shape corresponding to the shape of No. 5 is formed. Further, in the lower cushioning member 10, a triangular engaging projection 14 corresponding to the engaging hole 9 is formed so as to project downward at the central portion of the lower surface, and escape recesses 15 are provided at both ends of the upper surface. The protrusion 16 is formed on the outer side portion of the upper surface while being formed. The lower cushioning member 10 configured in this way is used in the bottom box 1
The fitting concave portion 13 is fitted to the bending piece 5 by being disposed inside the rising piece portion 3 so as to be parallel to the rising piece portion 3 and being moved to the rising piece portion 3 side so as to be in close contact therewith. Together with the fitting projection 12 is fitted into the fitting recess 8 and
14 is fitted into and engaged with the engagement hole 9, and is attached to the bottom box 1. Then, in this state, the mounting projection 11 is mounted on the upper end of the overlapping portion of the end of the rising piece 4 and the bent piece 5.

Then, the case of packaging a packaged object, for example, a refrigerator will be described. First, a refrigerator (not shown) is placed on the pair of lower cushioning members 101. At this time, the bottom leg of the refrigerator fits into the escape recess 15. Then, a rectangular outer box 18 made of corrugated cardboard having an open lower surface and a flap 17 at the upper opening is put on the refrigerator, and the open lower surface is fitted to the outer peripheral portion of the bottom box 1. After that, the flap 17 is closed and sealed with the adhesive tape 19, and then the outer box 18 and the bottom box 1 are wound up and down so as to straddle the both, thereby binding them together.

As described above, according to the embodiment, the fitting projection 12 at the end of the lower cushioning member 10 is inserted and fitted into the fitting recess 8 of the bottom box 1 from the inside of the bottom box 1 and the engagement projection of the lower surface is formed. Since the portion 14 is fitted into the engaging hole 9 of the bottom plate 2 and engaged therewith, the upper cushioning portion 12 abuts the upper side portion 7 to prevent the lower cushioning member 10 from slipping upward, and the inner side is prevented. The engagement of the engaging projection 14 with the engaging hole 9 prevents the lower cushioning member 10 from being securely attached to the bottom box 1 without using an adhesive unlike the conventional case. Since the fitting projection 12 is fitted into the fitting recess 8 and the engagement projection 14 is fitted into the engagement hole 9 as described above, the mounting can be performed easily.
