Keep it on the outside. Like the side surface portion 30b, the side surface portion 30a is also folded.

Further, the side surface portions 130a and 130b of the bottom semi-finished product are also folded in the same manner as the side surface portions 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 as to be located on the outside of the assembly.

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

Further, 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 crease line 81 are substantially parallel. By doing so, the withstand voltage strength of the assembly 10 can be further improved.

Further, the projecting piece portion 131 is preferably 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.
