DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an imitation paper, and more particularly, to an imitation paper provided to be capable of folding a plurality of sheets.

[0002]

2. Description of the Related Art Conventionally, in offices and schools,
Patterned paper has come to be widely used to create notices and make presentations. Since the imitation paper has a larger plane area than a standard-size paper that is usually used, the imitation paper is generally stored, sold, or carried in a rolled state.

[0003]

However, such an imitation paper is roll-shaped and bulky, making it extremely cumbersome to carry. In addition, a large space for sale or storage is secured. Inconvenience. In addition, when the imitation paper is used in a spread manner, since the habit when the paper surface is rolled remains, it is difficult and complicated to attach the paper on the wall surface or spread it on the table.

Here, in order to solve the above-mentioned inconvenience, it is conceivable to fold the imitation paper so as to have an appropriate size. However, in this case, since the plane area of the paper is large, the folding operation itself becomes troublesome. Since the folds are strongly left on the paper surface and cannot be maintained in a flat state, there is a reflexive disadvantage that writing at the folds becomes extremely difficult.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of such inconvenience, and its object is to make it possible to easily fold a plurality of sheets into a size suitable for storage and carrying, and Another object of the present invention is to provide an imitation paper which can be smoothly spread and used without being rounded.

[0006]

Means for Solving the Problems To achieve the above object, the patterned paper according to the present invention has a configuration in which a folded portion is provided on the paper surface so that a plurality of sheets can be folded. According to such a configuration, storage and carrying can be easily performed in a folded state without making the paper surface into a roll shape. In addition, since the paper does not have any roundness, the paper can be easily expanded for posting, writing, and the like.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS It is preferable that the folded portion in the present invention is constituted by perforations. According to such a configuration, the paper surface can be securely folded so that the folded portion does not become thick, so that the paper surface folding operation can be performed easily and quickly. Further, when the paper surface is widened, it is possible to prevent the fold at the folded portion from remaining strongly and to maintain the paper surface in a flat state. Further, it is possible to cut the paper into a required size according to the perforation.

Further, a configuration may be adopted in which a plurality of the folded portions are provided at predetermined intervals, and when the paper surface is folded at the positions of the folded portions, the paper surface is formed in a predetermined size. By adopting such a configuration, for example, when the paper is folded, the size is A4 or B5 or a size similar thereto, so that it can be stored and carried in the same manner as generally used documents and the like.

Further, when the paper surface is folded to a predetermined size, a binding margin forming portion is formed outside the size. With such a configuration, the paper can be bound and stored in a file or the like, which facilitates organization and storage, and also facilitates searchability.

Preferably, the perforations extend in a direction intersecting on the paper surface, and no perforations are formed in the intersecting region. With such a configuration, even when the sheet is frequently folded and unfolded, it is possible to effectively suppress the tearing from the perforated intersection area.

Further, it is preferable that the paper is configured so that ink or the like is not set off. Thereby, when writing on paper using an oil-based pen or the like, set-off to the folded paper can be effectively prevented.

[0012] Further, it is possible to adopt a configuration in which one surface of the paper is coated with a material for preventing the permeability of ink or the like. According to this, the set-off can be prevented in the same manner as described above, and the handling at the time of folding can be further improved.

[0013]

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

[First Embodiment] FIG. 1 is a schematic plan view showing a state in which a patterned paper according to a first embodiment is developed. In this figure, the paper surface 11 constituting the imitation paper 10
Is provided in a substantially rectangular shape, and the size thereof is not particularly limited. In this embodiment, however, in this embodiment, a generally widely available approximately 46-size size, that is, a lateral size of 78
8 mm and the vertical dimension are set to 1117 mm.

One surface of the paper surface 11 is coated with a material for preventing the penetration of ink or the like used for an oil-based pen, so that it is possible to prevent the ink from being set off by writing. The paper surface 11 includes a folded portion 12 extending to a position that divides the paper surface 11 into four in the vertical direction and the horizontal direction. When the paper surface 11 is folded at the position of the folded portion 12, the plane area of the paper surface 11 becomes the original flat surface. A plurality of sheets can be folded to have a thickness of about 1/16 of the area.

Each of the folded portions 12 is constituted by perforations 13, so that the paper surface 11 can be easily folded at these perforations 13 regardless of whether it is a mountain fold or a valley fold. I have. This makes it possible to sharpen the fold and prevent the fold from becoming thicker than when the paper 11 is folded manually. In addition, when the paper surface 11 is widened, the paper surface 11 can be maintained in a flat state without strong creases remaining in the perforations 13. The perforations 13 used in the present embodiment are micro perforations, and when the perforations 13 are difficult to cut, as shown in FIG. 2, the long width of the slit 13A forming the perforations 13 is used. L
1 is set to 2 to 4 mm, preferably about 2 mm, and the slit 13
The distance L2 between A is set to 1 to 3 mm, preferably about 1 mm. On the other hand, when the perforations 13 are easy to cut, as shown in FIG.
The distance L2 is preferably set to 0.2 to 0.4 mm, and the long width L1 is preferably set to about 0.28 m.
m, the interval L2 is set to about 0.23 mm, the long width L1 is set to about 0.5 mm, and the interval L2 is set to 0.3 mm.

Therefore, according to the first embodiment, it is possible to eliminate the necessity of storing and carrying the paper surface 11 in a roll shape, and it is possible to remarkably improve the handleability. . Further, when writing on a table or other top plate for writing on the paper surface 11, even when the plane area of the top plate is relatively small, the top plate is folded to 1/2 or 1/4 the original size. It is possible to easily perform writing or the like in the slanted state, and effectively prevent the paper 11 from protruding outside the top plate. Further, when the perforations 13 are easily cut, the paper surface 11 can be cut to a required size and used.

Further, since the paper 11 is coated with a hard-to-set material, even when writing is performed on the folded paper 11 with an oil-based pen or the like, ink is not attached to the lower paper 11 and the paper 11 is inadvertent. Stain can be prevented.

[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.

The second embodiment is characterized in that binding margin forming portions 15, 15 are provided at both left and right ends in FIG. That is, as shown in FIG. 4B, when the sheet surface 11 is folded at the position of the folding portion 12, these binding margin forming portions 15 and 15 are outside the sheet surface 11 (the left side in FIG. 4B). ). In this state, the binding margin forming unit 1
5, binding holes 16 are provided at two positions in the plane.

Therefore, according to the second embodiment, the paper 11 can be bound in a two-hole ring file or the like in a folded state, and can be stored in an even easier and more compact state. Can be.

[Third Embodiment] In the third embodiment, as shown in FIGS. 5 and 6A, the perforation 13 is partially formed in the intersection area S of the perforations 13 extending in the vertical and horizontal directions. It is characterized in that it is not formed in a uniform manner. The range in which the perforations 13 are not formed in the intersection area S is not particularly limited, but is 2 degrees from the intersection position.
The range is set to about 3 mm. Thereby, it is possible to effectively prevent the intersection area S from being broken by a plurality of folding operations or careless external force, and it is also possible to perform the folding operation on the sheet 11 similarly to the first embodiment. . Note that, as shown in FIGS. 6B and 6C, the same effect can be obtained by partially not forming any one of the perforations 13 in the vertical direction or the horizontal direction. Becomes

In each of the above embodiments, the position and the number of the folded portions 12 are not limited to the illustrated example, but may be changed or increased or decreased as needed in accordance with the required size of the sheet 11 after folding. You may.

The paper surface 11 may be colored or may have a predetermined grid drawn thereon. In particular, a configuration in which the grid and the folded portion 12 are made to coincide with each other may be adopted. This makes it easier to visually determine when folding or cutting out.

[0025]

As described above, according to the present invention, since a plurality of sheets can be folded by providing a folded portion on the paper surface, the paper can be easily stored and carried without making the paper surface a roll shape. Not only can it be done, but also because the paper does not have any roundness, it is possible to smoothly paste it on a wall surface or perform a writing operation.

When the folded portion is formed by perforations, the sheet can be folded firmly to simplify the folding operation, and when the sheet is expanded, the fold remains strongly. The paper surface can be kept flat by preventing such a situation. Further, the paper surface can be easily separated at the perforation position.

Further, since a plurality of folded portions are provided at predetermined intervals and the paper surface can be folded to a predetermined size, for example, by setting the size of the paper surface after folding to A4 or B5 or the like, a normal size can be obtained. It can be stored and carried like documents.

Further, when the sheet is folded to a predetermined size, a binding allowance forming portion is formed outside the size, so that the sheet can be bound and stored in a file or the like, which facilitates organization and storage. Can be achieved.

Further, when the perforation is not formed in the intersection area, even if the sheet is frequently folded and unfolded, it is possible to effectively avoid the tear from the intersection area. it can.

Further, in the case where the paper surface is configured not to set off with ink or the like, when writing with an oil-based pen or the like, it is possible to effectively eliminate the set-off to the paper surface which is folded and located in the lower layer.

Further, when one side of the paper is coated with a material for preventing the permeability of ink or the like, set-off can be prevented in the same manner as described above, and the handling property at the time of folding can be further improved. It becomes possible.
