By being inserted into the binding string mounting hole 5 and exposed to the outside of the cover body 1, both the inside and outside surfaces of the front cover portion 3 or the back cover portion 4 are sandwiched between the inner sandwiching piece 11 and the outer sandwiching piece 12. In this manner, the binding strap 8 is attached to the cover 1. It is those comprising a formation.

[0005]

【Example】

 Hereinafter, the illustrated embodiment will be described. First, in the figure, reference numeral 1 denotes a cover body made of a thin plastic sheet, and the cover body 1 has a spine portion 2 in the center portion, and a front cover portion 3 and a back cover portion 4 on the left and right sides thereof. Each is connected to bend freely.

[0006] A pair of upper and lower binding cord mounting holes 5 are formed near the spine 2 in the front cover 3 (see FIG. 2). The binding string attachment hole 5 is formed by providing a U-shaped cut in the front cover part 3 and folding a portion surrounded by the cut on the inner surface side of the front cover part 3.

[0007] A pair of upper and lower binding straps 6 are provided upright on the inner surface of the back cover 4 near the spine 2 so as to correspond to the binding strap mounting holes 5. . The binding cord locking piece 6 is also formed by providing a large and small double U-shaped cut in the back cover portion 4 and bending and raising a portion surrounded by the two cuts toward the inner surface side of the back cover portion 4. It has a through hole 7 through which a binding string 8 described later can be inserted.

Next, in the drawing, reference numeral 8 denotes a plastic binding string. The binding cord 8 has a structure in which a clip 10 is integrally provided at the base end of a flexible cord portion 9, and the clip 10 has a pair of sandwiching pieces 11, 12 inside and outside. The outer clip 12 has a claw 13 protruding rearward at a rear end continuous with the inner clip 11, and the inner clip 11 has a projection 14 on its inner surface. .

The binding strap 8 is formed by inserting the clip 12 outside the clip 10 into the binding strap mounting hole 5 of the front cover part 3 of the cover body 1 from the inside and exposing the clip piece 12 to the outside of the front cover part 3. The front cover 3 is attached with the inner and outer surfaces sandwiched between the pair of inner and outer sandwiching pieces 11 and 12. The nail 13 projecting from the outer clip 12 is engaged with the edge of the binding string attachment hole 5, and the projection 14 provided on the inner clip 11 is attached to the binding strap mounting hole 5 of the front cover 3. In order to prevent the clip 10 from coming off the binding string attachment hole 5, the clip 10 is hooked on the leading edge of the folded turning piece 15 when forming the clip.

When binding a document or the like, as shown in FIG. 3, the binding portion 9 of the binding string 8 is bent inward and inserted into a hole of the document or the like (not shown), and then the binding is performed. The leading end of the binding portion 9 is inserted into the through hole 7 of the binding cord locking piece 6, and the locking projection 16 provided on one surface of the binding portion 8 is hooked on the edge of the through hole 7 of the binding string locking piece 6. Let it.

[0011]

[Effect of the invention]

 The file of the present invention is as described above. First, the cover body 1 can be easily formed at a low cost because the binding strap mounting hole 5 and the binding strap locking piece 6 can be easily formed by punching. is there. Next, the binding cord 8 can be easily attached to the cover 1 simply by inserting the outer clip 12 of the clip 10 into the binding cord attachment hole 5, so that the assembling process of the binding cord 8 is facilitated. effective. Further, by providing the claw pieces 13 and the protrusions 14 as described in claim 2, an effect is obtained that the binding cord 8 is hard to be detached from the cover body 1.
