Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a paper clip used for binding papers such as copy paper, albums, and clear files, and more specifically, the invention relates to a paper clip used for binding papers such as copy paper, albums, and clear files. This paper clip has a strong structure and facilitates binding of paper.

[Conventional technology]

As a conventional paper clip,
Known examples include those shown in 16012 and Utility Model Publication No. 49-32714.

These paper clips have a slit formed in one wall surface of a pair of cylinders having a substantially square cross section, but this one wall surface is not a depressed wall surface as in the present invention.

In addition, the opening width of the slit is designed to accommodate fairly thick magazines, and the cover body is attached to the clip body, but both can be attached simply by pasting the back of the clip body to the cover body. This is the only composition.

[Problem that the invention attempts to solve]

As mentioned above, in conventional paper clips, the slit-forming surface is not formed on the depressed wall surface, but simply on the smooth surface.
The problem is that the cut end of the slit comes into contact with the paper at right angles, and as a result, when a pull-out force is applied to the paper held in the clip body, the pull-out restraining force is difficult to apply to the paper, making it easy to pull out. The dot was hot.

Furthermore, since the clip body and the cover body were attached only at the back, there was a problem in that the attachment strength was poor.

Furthermore, conventional paper clips have had other problems, such as the lack of a guide section to introduce paper into the clip main body during a binding operation, making it inconvenient.

The technical problem of the present invention is to provide a paper clip that solves the above problems.

[Technical measures taken to solve the technical problems of the invention] The technical measures taken to solve the technical problems were to make one wall of a cylinder with a substantially square cross section cave inward, and to create a depressed wall surface. a clip body formed by forming a slit large enough to hold even a piece of paper in the center longitudinal direction of the depressed wall surface, and integrally attached to the clip body in a state where the depressed wall surface of the clip body is sandwiched. The clip body and the cover body are attached by attaching the three sides of the clip body excluding the depressed wall surface to the cover body near the back cover. A notch is formed at the end of the opposing wall to serve as a paper introduction guide.

[Effect]

In the present invention, the width of the slit is large enough to hold even a single sheet of paper, and the overall cross-sectional shape is approximately M-shaped so that the cut end of the slit exerts a pulling force against the paper. It can securely hold sheets of paper to one sheet of paper, and the clip body and cover body are attached by attaching three sides of the clip body, excluding the recessed wall surface, to the cover body near the spine. Therefore, the attachment is strong, and since notches are formed as paper introduction guides at both ends of the opposite wall of the depressed wall surface of the clip body, the binding operation is facilitated.

〔Example〕

To explain the present invention with reference to the embodiments shown in the drawings, FIG. 1 is a perspective view of the present invention, and FIGS. 2 and 3 are other embodiments.

In the figure, reference numeral 1 indicates a clip body made of PVC or the like, 1a indicates a depressed wall surface of the clip body, and 1b
2 is a wall surface opposite to this depressed wall surface, and 2 is a slit formed in the longitudinal direction of the center of the depressed wall surface.A cover body 3 is attached to the clip body 1 so as to sandwich the depressed wall surface. The cover body 3 is made of a material with appropriate strength, and its size can be freely selected depending on the size of the paper to be bound.

Furthermore, reference numeral 4 is a notch formed at the end of the opposing wall surface 1b as a paper introduction guide, and although the shape of the notch 4 may be any shape, it is usually preferably triangular.

In the above configuration, when binding papers to the clip body 1, first staple the papers, position the edges of the papers where the staples are in the internal space of the clip body 1, and then Papers are slipped into the slit 2 from the ends of the clip body 1 (the upper and lower ends in FIG. 1) so that they protrude outward from the recessed wall surface 1a of the clip body 1. In this way, since the thickness of the staple portion is large, the papers bound in the clip body 1 will not be pulled out through the slit, and a stable binding effect can be obtained.

If a notch 4 is formed at the end of the opposing wall surface 1b as shown in FIG. 2, it can serve as a guide for introducing paper into the clip body 1, making the binding operation easier. There are some advantages.

Furthermore, as shown in FIG.
When more than one paper is arranged in series, it has the advantage of being able to handle the binding of a large number of papers, and also making it possible to classify and organize them according to their contents. When attaching the clip main bodies 1, assembly can be easily performed by using fusion bonding, double-sided tape, or an appropriate adhesive.

[Effect of idea]

Therefore, according to the present invention, since the clip main body and the cover body are provided integrally, the papers bound to the clip main body can be completely protected, and important papers can be prevented from being soiled or damaged. Even if it is a sheet of paper, it is difficult to pull out, the connection between the clip body and the cover body is strong, and the presence of the notch that serves as a guide has the excellent effect of simplifying the binding operation.

Claims (1)

[Scope of utility model registration request] A clip body formed by recessing one wall surface of a cylindrical body having a substantially square cross section inward to form a recessed wall surface, and forming a slit large enough to hold even a piece of paper in the central longitudinal direction of the recessed wall surface. It consists of a cover body having a moderate strength that is attached integrally with the clip body while sandwiching the depressed wall surface of the clip body, and the attachment of the clip body and the cover body is performed by covering three sides of the clip body excluding the depressed wall surface. A paper clip that is attached to a cover body and near a back cover, and has a cutout portion as a paper introduction guide formed at an end of a wall surface opposite to a recessed wall surface of the clip body.
