Hereinafter will be described in more detail through the accompanying drawings showing a preferred embodiment of the present invention.

First, FIG. 2 shows a folded box as a preferred embodiment of the present invention, FIG. 3 shows a folded box, and FIG. 4 shows a folded box. 5 shows an A-A cross section of FIG. 2 and a B-B cross section of FIG.

As shown, the front side plate 110 and the rear side plate 120 installed at both front and rear sides of the lower plate 100 are composed of a center plate 111 and 121, a left edge plate 114 and 124, and a right edge plate 115 and 125, respectively. The front side plate 110 and the rear side plate 120 is rotatably installed on the lower plate 100, preferably to be connected to the hinge as shown in Figures 2, 6 and 7.

As shown in FIG. 2, the middle plates 111 and 121 are formed of upper overlapping portions 112 and 122 formed at an upper portion thereof and lower overlapping portions 113 and 123 formed at a lower portion thereof. The left corner boards 114 and 124 are connected to the lower overlapping parts 113 and 123 on the left side as shown, and the right corner boards 115 and 125 are connected to the lower overlapping parts 113 and 123 on the right side. Here, the connection of the lower edge plates 114 and 124 and the lower edge portions 113 and 123 of the right edge plates 115 and 125 is connected by a hinge to be rotatable, and preferably the left edge of the left edge as shown in FIG. Integral hinges 160, 161, 162 and 163 are preferably formed such that the plates 114 and 124 and the right corner plates 115 and 125 and the center plates 111 and 121 are integrally connected. As a result, the front side plate 110 and the rear side plate 120 are each capable of plastic injection molding.

When the front side plate 110 and the rear side plate 120 is rotated and stacked on the lower plate 100, the left edge plates 114 and 124 and the right edge plates 115 and 125 are above the lower overlapping portions 113 and 123. Only overlaps the upper overlapping portion (112, 122) does not overlap. At this time, the upper overlapping portions 112 and 122 of the front side plate 110 and the rear side plate 120 are overlapped with each other as shown in FIG. Thus, even if the height of the front side plate 110 and the rear side plate 120 is greater than the width of the lower plate 100 between the front side plate 110 and the rear side plate 120 can be smoothly deployed and folded Done.

In addition, the front side plate 110 and the rear side plate 120 preferably includes elastic means for providing a predetermined elastic force so that it is maintained in an unfolded state. Such an elastic means has an effect of automatically unfolding the box with its elastic force after the box has been deployed to a predetermined limit in a folded state, thereby making it convenient for use. And, more preferably, the elastic means may be provided with an elastic force to be maintained in the state even in the folded state of the box.

The elastic means 191, 192, 193, 194 shown in FIG. 2 is the first bending part 195 and the left corner plate 114, 124 integrally connected to the lower overlapping parts 113, 123, as shown in FIG. It consists of a second bending part 196 which is integrally connected to. In addition, the first bending part 195 and the second bending part 196 are connected by an integral hinge 197, and the first bending part 195 has a lower overlapping part 1 as shown in FIG. 8.
