Keep it on the outside. The side surface portion 30a is also folded like the side surface portion 30b.

  The side parts 130a and 130b of the bottom semi-finished product are also folded in the same manner as the side parts of the upper semi-finished product. However, since there is no protruding piece on the side surface of the upper semi-finished product, it is not necessary to fold the protruding piece so that it is located outside the assembly.

  Next, folding of the protruding piece portion, which is the finishing of the assembly, will be described. FIG. 8 is a diagram for explaining insertion of the protruding piece portion, which corresponds to at least one of the embodiments of the present invention. The protruding piece 131c provided on the side surface portion 130b is inserted into the protruding piece insertion port 32c provided on the side surface portion 30b. When inserting, fold along the crease line 81 from the front to the front back. Here, when the protruding piece 131 is larger than the protruding piece insertion port 32, it is preferable to fold the protruding piece 131 while further bending it. By doing so, when the protruding piece portion is inserted and locked, the locking portion is less likely to come off, and more stable combination can be achieved.

  Furthermore, it is preferable that the direction of the force applied to the assembly 10 when the article is placed and the direction of the line formed by the fold line 81 are substantially parallel. By doing so, the compressive strength of the assembly 10 can be further improved.

  Further, it is preferable that the projecting piece portion 131 be bent so as to cover the side surface portion 30. By doing so, the corners of the assembly 10 can be protected, the durability of the assembly 10 can be further improved, and the assembly 10 can be disassembled and used again after use.
