The upper and lower bearings of this pongee 12c are fixed to the simple 12a, bearing 1]2m and bearing l'1fil 2b.
A gap of 41 openings is provided between the opening and the opening, and the pongee holder 1fj12b is designed to slide up and down within the gap between the opening and the opening. The folding container is constructed as described above, and the state shown in FIG. 1 is the assembled state, and the state shown in FIG. 2 is the folded state. When the end plates 2 at both ends are tilted inward from the state shown in FIG. 1, they bend inward at the hinge portions 9 and 12.
The center plate 3a overlaps the bottom plate 1, the gA end plate 3b slides toward the upper end, the side end plate 3b overlaps the inner surface of the end plate 2, and the end plate 2 overlaps the bottom plate 1 via the side end plate 3b. It is folded as shown in Figure 2. At this time, the side plates 3 are also folded by simply tilting the end plates 2 at both ends inward, and can be folded with a single operation. Also the second
If the end plate 2 is stood up so as to expand outward from the state shown in the figure, the end plate 2 will stand up vertically, and the hinge portion 9 will move so that the center plate 3a and side end plate 3h of the side plate 3 go outward. The hinge portion 12 rotates, the center plate 3a stands up, and the side edges [3b] slide toward the lower end with respect to the end plate 2 and stand up vertically. In this way, by simply standing up the end plates 2 at both ends so as to spread them outward, the side plates 3 can also be erected 4, and can be assembled in one operation. When the end face @2 and the side plate 3 are stood up, the edge 6 rises on the bottom plate 1.
, the end face @2 and the side plate 3 are prevented from rotating further outward. When the side plate 3 is erected, the four step portions 10.1] fit into each other, and the center plate 3a and the side end plates 3b form a flat plate and are held as a single piece of the side plate 3. This and light central plate 3a
