DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a writing paper,
More specifically, the present invention relates to a writing sheet provided to be foldable into a plurality of sheets.

[0002]

2. Description of the Related Art Conventionally, as a writing paper to be bound in a notebook or a notebook, there is known a writing paper having a perforation extending in a vertical direction and a horizontal direction on a paper surface and capable of folding a plurality of sheets. . This writing paper is provided in a size that fits within the cover of the notebook when the paper surface is folded at the perforation position, and when the paper surface is unfolded, the writing paper becomes larger than the cover and performs writing or the like. Is available.

[0003]

However, in such a writing paper, if the paper is repeatedly folded and unfolded, the paper is torn from the intersection of perforations extending in the vertical and horizontal directions of the paper. However, there is a disadvantage that a hole is formed. This is due to the fact that the vertical and horizontal perforations overlap at the intersection position, and the strength is weakened.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised in view of such inconvenience, and an object of the present invention is to provide a writing paper capable of preventing tearing at the intersection of perforations intersecting on the paper. To provide.

[0005]

In order to achieve the above object, the present invention comprises at least two perforations extending in a direction intersecting on the paper surface, and a non-perforation forming portion is provided in an intersecting region of these perforations. , Is adopted.
According to such a configuration, the perforations do not overlap at the intersections of the perforations, so that the strength at the intersections is higher than that of the conventional type of writing paper, and the folding and unfolding of the sheet frequently occur. Even if you do,
Breakage from the intersection position can be effectively suppressed.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the perforations include a first perforation extending in the longitudinal direction of the paper and a second perforation extending in the lateral direction, and the non-perforation forming portion includes a first perforation. It can be formed by partially missing at least one of the first and second perforations. According to such a configuration, for example, when only the first perforation is missing, the second perforation can be continuously provided, so that both the first and second perforations are missing. The easiness of folding can be maintained as compared with the case where it is folded.

[0007] Furthermore, the paper surface can be configured to be bundled in a notebook shape with a plurality of sheets as one unit. In such a configuration, for example, the writing paper is a notebook with a cover, and the paper surface has a flat area larger than the cover, and when folded at the position of the perforation, the writing paper has a substantially same flat area as the cover. In this case, the perforated intersection position is located at the corner of the notebook. However, careless tearing at the corner can be prevented, and the appearance can be maintained in a good appearance. Also, when a memo is written on a part of the paper, the memo area can be separated from the note along the perforation,
Convenience such as handing to a person or storing in a pocket can be obtained.

[0008] Regarding the perforations referred to in the present specification, the term "one perforation" includes a case where a perforation is missing in the middle. Further, the “writing paper” in this specification refers to a paper mainly used as a daily necessity, and is used as a concept including a notebook, a memo pad, a middle sheet of a learning notebook, a report sheet, a loose leaf, a memo sheet, and the like.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment] FIG. 1 is a schematic perspective view of a writing paper according to a first embodiment applied to a notebook, and FIG. 2 is a plan view of the notebook. Have been. In these figures, a notebook 10 includes a front cover 11 and a back cover 12 which are provided to be openable and closable, and
1 and a plurality of writing papers 13 bound in a state of being bound between the back cover 12.

Each of the writing papers 13 is composed of a rectangular paper surface 15 having a plane area approximately four times as large as the front cover 11 in the unfolded state. It is rare. The paper surface 15 is a two-row perforation 1 extending in a direction substantially orthogonal to the center position on the paper surface 15.
6 so that the paper surface 15 can be folded and cut off at the position of the perforation 16. Further, the paper surface 15 is bound together with the front cover 11 and the back cover 12 via a binding portion 17 (see FIG. 1) that performs substantially the same operation as the perforation 16 at the upper half position at the left end in FIG. ing.

The perforation 16 comprises a first perforation 18 extending in the longitudinal direction of the paper surface 15 and a second perforation 19 extending in the lateral direction. This perforation 16
Is a micro perforation, and when the perforation 16 is difficult to be separated, as shown in FIG.
6, the long width L1 of the slit 16A is set to 2 to 4 mm, preferably about 2 mm, and the distance L between the slits 16A is set to L.
2 should be set to 1 to 3 mm, preferably about 1 mm. On the other hand, in the case where the perforations 16 are easy to separate, FIG.
As shown in the above, the long width L1 is 0.2 to 0.6 m
m, the interval L2 is preferably set to 0.2 to 0.4 mm, and preferably, the long width L1 is set to about 0.28 mm, the interval L2 is set to about 0.23 mm, and the long width L1 is set to about 0.23 mm.
Is set to about 0.5 mm, and the interval L2 is set to 0.3 mm. Here, a non-perforation forming part 20 is provided in the intersection region S of the first and second perforations 18 and 19.

The non-perforation forming section 20 is shown in FIG.
As shown in FIG. 7, both the first and second perforations 18 and 19 are partially omitted in the intersection area S. The range in which the perforations 13 are missing is not particularly limited, but is set to a range of about 2 to 3 mm from the intersection position of the first and second perforations 18 and 19, and carelessness at the intersection position is made. It is designed to prevent tearing.

Incidentally, the non-perforation forming section 20 is provided as shown in FIG.
The configuration as shown in (B) and (C) can be used instead. That is, as shown in FIG. 5B, only the first perforation 18 is partially missing,
As shown in (C), only the second perforations 19 are partially omitted. With such a configuration, it is possible to obtain the paper 15 with easier folding than the configuration in which both the first and second perforations 18 and 19 are omitted.

Therefore, according to the first embodiment, since the first and second perforations 18 and 19 do not overlap with each other, even when the folding and unfolding of the sheet 15 is repeatedly performed, It is possible to effectively prevent tearing and perforation in the intersection area S. In addition, paper space 15
Is provided so as to be separable at the position of the perforation 16 and the spelling part 17, so that the writing paper 13 can be cut off to a required size and used, and good handling can be maintained.

[Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIG. In the following description, the same or equivalent components as those of the first embodiment will be denoted by the same reference numerals as necessary.
Description is omitted or simplified.

In the second embodiment, the plane area of the paper surface 15 is substantially the same as the cover 11, and the binding edge 1 of the paper surface 15 is
It is characterized in that a binding margin 22 is provided along 5A. The binding margin 22 is formed by providing a third perforation 23 at a position adjacent to the binding edge 15A. A non-perforation forming part 20 is also provided at the intersection of the third perforation 23 and the second perforation 19.

Therefore, according to the second embodiment, the binding margin 22 is provided on the binding edge 15A side of the paper surface 15, so that a plurality of paper surfaces 15 are cut off at the position of the third perforation 23. , Each writing paper 13 and cover 1
1 and the back cover 12 can be reliably maintained in the binding position without scattering. Also, the third
The non-perforation forming portion 20 is also provided at the intersection of the second perforation 23 and the second perforation 19.
Even when the page is turned at the position 3, it is possible to prevent tearing at the intersection position.

The position and number of the perforations 16 are not limited to the illustrated example, but are
Various design changes are possible, such as changing and increasing the size according to the size and the like. For example, as shown in FIG. 7, two second perforations 19 are provided at the center of the paper surface 15 and below the paper surface 15, and the first perforations 18 are located at the lower end of the paper surface 15 from the center second perforation 19. 8, or may be provided with an inclined perforation 25 extending in a direction inclined with respect to the vertical and horizontal directions of the paper surface 15, as shown in FIG. In short, the present invention suffices if the non-perforation forming part 20 in which the perforation 16 is partially missing is provided in the intersection area of the perforation 16.

The case where the writing paper 13 is applied to the notebook 10 has been described. However, the present invention is not limited to this, and can be similarly applied to writing paper such as memo pad, report paper, and loose leaf.

[0021]

As described above, according to the present invention, since the non-perforation forming portion is provided at the intersection area of at least two perforations extending in the direction intersecting on the paper surface, the perforation at the intersection position of the perforation is provided. Are not overlapped with each other, the strength is increased, and even at the time when the sheet is frequently folded and unfolded, it is possible to make it difficult to cause tearing at the intersection position.

The perforations include a first perforation extending in the longitudinal direction of the drawing and a second perforation extending in the lateral direction, and the non-perforation forming portion includes the first and second perforations. Since it is formed by partially missing at least one, for example, if only the first perforation is missing, the second perforation can be continuously provided, so that the first and second perforations can be formed. This makes it easier to fold than when both perforations are missing.

Further, since the paper surface is bound in a notebook shape with a plurality of papers as one unit, for example, writing paper is applied to the notebook, and each paper surface is bound in a state where the paper surface is folded at the perforation position, and Even when the eye intersecting region is located at the corner of the note, it is possible to prevent inadvertent tearing at the intersecting position and to maintain a good appearance of the entire note.
