  Further, in the punched side sheet material 4, each outer side plate 43 is folded along the crease s on the lower surface of each side plate 42, and each side plate 42 together with the outer side plate 43 with respect to the bottom plate 41. As shown in FIG. 14, side members 4 </ b> A having side walls 4 </ b> L and 4 </ b> R are formed by folding side plates 42 and outer side plates 43 on the left and right sides of the bottom plate 41, respectively.

  Next, as shown in FIG. 15, the bottom surface material 3 </ b> A is disposed and locked on the top surface of the bottom surface plate 21 of the surrounding sheet material 2 with the upper bottom surface plate 34 facing upward. Specifically, the locking pieces 21x of the surrounding sheet material 2 and the locking pieces 33x, 34x of the bottom surface material 3A are formed slightly to the right of the middle in the left-right direction, so that they are arranged so as to overlap. Thus, the front and rear surfaces of the bottom surface material 3A are defined relative to the surrounding sheet material 2 and positioned in the left-right direction. Thereafter, the locking piece 21x of the surrounding sheet material 2 is flipped upward by a finger through the operation holes 22a and 25a, so that the locking piece 21x of the surrounding sheet material 2 is positioned at the lower bottom of the bottom surface material 3A facing upward. The locking piece 33x of the face plate 33 and the locking piece 34x of the upper bottom plate 34 are sequentially pushed up, and the substantially trapezoidal space formed by pushing up the locking pieces 33x, 34x, and further the bottom plate 31 As a result of entering the locking holes 31b and the locking notches 31c formed at the respective front and rear end portions, the bottom material 3A is engaged with the bottom plate 21 of the surrounding sheet material 2 so as not to move via the locking pieces 21x. Can be stopped.

  Next, as shown in FIG. 16, the side member 4 </ b> A is arranged on the upper surface of the upper bottom plate 34 exposed between the left and right engaging plates 32 of the bottom member 3 </ b> A locked to the surrounding sheet material 2 and locked. Specifically, the front and rear engaging convex portions 431 of the outer side surface plates 43 constituting the side walls 4L and 4R of the side surface material 4A are formed in the front and rear engaging concave portions 323 and 324 of the left and right engaging plates 32 of the bottom surface material 3A. , 432 are engaged with each other to position and arrange the side surface material 4A with respect to the bottom surface material 3A while defining front and rear and left and right. At this time, since the locking notch 41a of the bottom plate 41 of the side member 4A faces the locking piece 34x of the upper bottom plate 34 of the bottom member 3A, the locking piece 21x of the surrounding sheet material 2 is again fingered. By flipping up, the locking piece 33x of the lower bottom surface plate 33 and the locking piece 34x of the upper bottom surface plate 34 of the bottom surface member 3A are pushed up in order through the locking piece 21x, and the locking pieces 33x and 34x are side surfaces. As a result of entering the locking notch 41a of the bottom plate 41 of the material 4A, the side member 4A can be locked to the bottom plate 31 of the bottom material 3A so as not to move via the locking pieces 33x and 32x.

  At this time, the guide hole 34a and the locking hole 34b of the upper bottom surface plate 34 of the bottom surface material 3A communicate with the guide hole 41b and the locking hole 41c of the bottom surface plate 41 of the side surface material 4A.

  Next, although not shown in detail, after raising the standing plate 52 of the auxiliary bottom sheet material 5 along the crease t with respect to the bottom plate 51, the standing bottom plate 52 is directed rearward and the auxiliary bottom sheet material 5 is Arranged on the bottom plate 41 of the side member 4A.
