Meanwhile, a conical shape is formed by bending toward the back side along each radial ruled line 6 .

Next, as shown in FIG. 3B, the connection portion 5 is connected to one side of the body portion 2 . In this connection, the cooperation of the first slot 10 and the second slot 12 causes the first tongue 15a of the connecting portion 5 to overlap the first tongue 15b of the connecting region 11 and the first tongue 15b of the connecting portion 5 to overlap. This is done so that the regions on both sides of one tongue 15 a overlap under the regions on both sides of the first tongue 15 b in the connecting region 11 .

Then, as shown in FIG. 3C, the second tongue 16a of the connection portion 5 is pushed down and bent inward together with the second tongue 16b of the connection region 11. As shown in FIG. As a result, the second tongue piece 16a meshes with the cut line 13 of the second tongue piece 16b, and the connecting portion 5 is connected to the connection region 11 more reliably. This forms a megaphone 18 as shown in FIG. 3C. The mouth of the megaphone 18 is smoothly formed by the curved ruled line 7 .

On the other hand, when using the board 1 as a hat, three boards 1 are used. That is, as shown in FIGS. 4A to 4C, by connecting the connecting portion 5 of each plate member 1 to the connecting region 11 of another plate member 1 to form a conical shape, a cap 19 as shown in FIG. 4C is formed. is formed.

At this time, the first slot 10 of the connecting portion 5 of each plate 1 and the second slot 12 of the adjacent plate 1 are used as in the case of forming the megaphone 18, as shown in FIG. 4B. That is, the first tongue 15b between the second slots 12 is superimposed on the first tongue 15a between the first slots 10, and the regions on both sides of the first tongue 15a in the connection portion 5 are the connection regions 11. are overlaid on the regions on both sides of the first tongue piece 15b in .

Then, as shown in FIG. 4C, the second tongue 16b of the connection region 11 of each plate member 1 is pushed down and bent inward together with the second tongue 16a of the corresponding connection portion 5. As shown in FIG. As a result, the second tongue piece 16b meshes with the cut line 13 of the second tongue piece 16a, and the connection portion 5 of each plate member 1 is more reliably connected to the connection region 11 of the adjacent plate member 1. As shown in FIG.

At this time, as shown in FIG. 4B, the folded portion 20 of the main body portion 2 of each plate 1 that is closer to the center than the fold line 8 is folded along the fold line 8 so that the folded portion 20 is located inside the cap 19 . Further, it is bent toward the back side along the arc-shaped ruled line 7 . Thereby, a hat 19 as shown in FIG. 4C is formed.

As described above, according to the present embodiment, since the board 1 is made of corrugated cardboard, the fan 17 is light and does not bend when fanned, and the megaphone 18 or cap 19 with high strength is formed. can be formed.

In addition, the folding fan 17 is used by grasping the folded portion 20 folded back along the fold-back ruled line 8 of the main body 2 and the portion of the main body 2 overlapping this, so that the overlapped portion can be replaced by the other portion. It is thicker and easier to grip, so it can be gripped and fanned well.

In addition, as shown in FIG. 2, each ruled line 6 intersects the part on the folded part 20 and the part other than the folded part 20 of the main body part 2, so that when it is held and used as described above, The strength of the fan 17 can be increased.

Further, when the plate 1 is held as it is and used as a fan, the plate 1 tends to swing with the fingertips of the holding hand as a fulcrum, making the holding of the fan unstable and difficult to use. In this respect, according to the present embodiment, by holding the fan 17 via the folded portion 20, the tip portion of the folded portion 20 is closer to the outer edge 3c of the main body 2, and the wind pressure is applied more. The fan 17 can be gripped while supporting the . As a result, the fan 17 can be used while being held in a more stable posture.

Further, the first slot 10 of the connecting portion 5 and the second slot 12 of the connecting region 11 facilitate and firmly connect the connecting portion 5 and the connecting region 11 when forming the megaphone 18 or the cap 19. can.

Further, the connection between the connecting portion 5 and the connecting region 11 can be made stronger by the first tongue 15a and the second tongue 16a of the connecting portion 5 and the first tongue 15b and the second tongue 16b of the connecting region 11. can be done.

Moreover, since the mouth portion of the megaphone 18 is formed by the portion bent along the arc-shaped ruled line 7, the user's mouth is not hurt and a good feeling of use can be obtained.

It should be noted that the present invention is not limited to the above-described embodiments, and can be implemented with appropriate modifications. For example, the plate material 1 is not limited to cardboard, and may be made of a light material that can be folded along other ruled lines, does not bend in the state of a fan, and is light.
