Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a severable sheet suitably used for printing or the like.
[0002]
[Prior art]
When it is necessary to cut and use a sheet of paper, etc., as an example, a business card etc. is printed on a predetermined area of the paper using a printer such as a printer connected to a personal computer, and the printed part is cut out as a business card etc. In the case of use, conventionally, a perforation is formed, and a portion to be used from this sheet is cut out using the perforation.
[0003]
[Problems to be solved by the invention]
However, when the portion to be used is cut out in this way, the portion that did not have the perforated through hole is sequentially broken, so the paper fibers etc. popped out when broken, and the portion that had the perforated through hole For example, irregularities are formed between the portions that are not so, and marks that are cut off by using perforations on the four sides remain, which causes a problem that it is not preferable in appearance for use as, for example, a business card or a design card.
[0004]
Therefore, the present invention is configured to solve the problems described above.
[0005]
[Means for Solving the Problems]
That is, the sheet according to the present invention comprises at least a base material and a coating layer formed without interposing an adhesive material on the front and back surfaces of the base material, and is set at the boundary of a predetermined region set on the surface. A continuous cut groove is provided that penetrates the coating layer on the front surface side and reaches the boundary between the coating layer on the back surface side and the base material or near the boundary, and the predetermined region can be cut off by bending along the cut groove. In addition, the predetermined area separated is accompanied by the coating layer on the back surface side .
[0006]
In accordance with this arrangement, the notches are not almost completely cut the base material, and since is continuous over substantially the entire area of the cutting area, the sheet is bent along the cut groove it can be cut without leaving substantially traces by. Further, since the cut groove does not penetrate the sheet, the sheet can be handled integrally. Either surface may be set as the surface.
[0007]
In particular, in order to prevent the sheet from warping during printing or the like, it is desirable that both surface layers forming the surfaces on both sides are made of the same material.
[0008]
Specifically, a form in which the sheet is formed mainly of photographic paper is conceivable.
[0009]
Further, in order to cut a predetermined region set on the surface without leaving any trace on the outer periphery, the cut groove may be provided so as to surround the region.
[0010]
And in order to cut | disconnect the area | region of standardized sizes, such as a business card and a postcard, what is necessary is just to set the shape of the said area | region according to the said standardized size.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0012]
The sheet S according to the present embodiment is formed mainly with the photographic paper I.
A schematic cross-sectional view thereof is shown in FIG.
[0013]
The photographic paper I includes a base material 1 made of paper and coating layers 21 and 22 which are layers of polyethylene coating.
[0014]
The coating layers 21 and 22 are formed by applying polyethylene to the front surface 1a and the back surface 1b of the base material 1 without using an adhesive material. Note that either surface may be set as the front surface 1a or the back surface 1b. The thickness of the coating layers 21 and 22 may be such that the stiffness of the entire sheet S is substantially equal to the stiffness of the base material 1, that is, the stiffness of the entire sheet S is not affected by the coating layers 21 and 22. .
[0015]
Next, the planar shape of the sheet S will be described with reference to FIG.
[0016]
The sheet S has a rectangular shape and is provided with continuous cut grooves 3 parallel to the long side and the short side, respectively. The shape of the cut groove 3 is such that it encloses a rectangular predetermined region 4 having a long side length x and a short side length y, and further protrudes from the four corners.
[0017]
Further, the long side and the short side of the predetermined region 4 are each equally divided into a plurality of portions (in this embodiment, the long side is divided into 5 equal parts and the short side is divided into 2 equal parts), and the region 4 is a side parallel to the long side. The cut groove 3 is further provided so as to be divided into rectangular regions 41 having a length of x / 5 and a length of a side orthogonal to the long side being y / 2. The cut groove 3 protrudes from the predetermined region 4 at both ends. In the present embodiment, the shape of each region 41 obtained by dividing the region 4 by the cut groove 3 is a business card size rectangle.
[0018]
Printing can be performed on the surface 5a of the sheet S by using a printer (a personal computer and a printer are not shown) connected to the personal computer. More specifically, a predetermined area 4 is set in the printable area 6 of the printer, and the predetermined contents are respectively given to the areas 41 divided by the cut grooves 3 by the printer. It is supposed to be printed.
[0019]
Thus, the cut groove 3 penetrates the coating layer 21 on the front surface side and reaches the back surface 1b of the base material, which is a boundary between the coating layer 22 on the back surface side and the base material 1. Such a cut groove 3 can be formed by pressing or other known techniques.
[0020]
When the sheet S on which the predetermined content is printed in the region 41 is bent along the cut groove 3, the sheet S is sequentially cut along the bent cut groove 3, and finally each region 41 is formed. It is separated and can be used as a business card.
[0021]
As described above, in the sheet S mainly composed of the photographic paper I including the base material 1 and the coating layers 21 and 22 bonded to the front surface 1a and the back surface 1b of the base material 1 without an adhesive material, the coating on the front surface side is performed. Since the continuous cut groove 3 which penetrates the layer 21 and reaches the boundary 1b or the vicinity of the boundary 1b between the coating layer 22 on the back surface side and the base material 1 is provided and can be cut along the cut groove 3, a mark is formed at the cut end. It can be cut without leaving any.
[0022]
Further, since the materials of the coating layers 21 and 22 on both sides are the same, it is possible to prevent the sheet from warping during printing. Further, the appearance of the front surface and the back surface can be made the same.
[0023]
Furthermore, since the cut groove 3 is provided so as to surround the predetermined region 4 set on the surface, the predetermined region 4 can be separated without leaving a trace.
[0024]
And since the area | region 41 which divided | segmented the predetermined area | region 4 was set to the business card size rectangle, the card | curd of the size standardized to the business card size from the sheet | seat S can be cut | disconnected.
[0025]
Note that the present invention is not limited to the embodiment described above. For example, the material of the coating layers 21 and 22 may be other than polyethylene, and need not be the same. Moreover, you may form by methods other than application | coating, for example, methods, such as spraying, extrusion, and a lamination process.
[0026]
Moreover, as long as it consists of the base material 1, and the coating layers 21 and 22 joined without interposing the adhesive material on the front surface 1a and the back surface 1b, it may be formed mainly from the photographic paper I. In addition, the base material 1 may be composed of a plurality of layers.
[0027]
Further, a sheet S may be used in which a coating is further applied on the surface coating layer 21. For example, the glossy layer 23 is further coated on the surface of the coating layer 21 on the surface of the photographic paper I whose schematic cross-sectional view is as shown in FIG. 3, and the glossy layer 23 and the surface coating layer 21 are penetrated. For example, a boundary 1b between the coating layer 22 on the back surface side and the base material 1 or a slit 3 that reaches the vicinity of the boundary 1b is provided. Further, it may be subjected to printability improvement processing such as providing a receiving layer such as ink or toner on the surface so as to be suitable for printing by an ink jet printer or a laser printer.
[0028]
Further, the sheet S may be used for other than business cards. In particular, the cut groove 3 does not need to surround the predetermined area 4 or protrude from the four sides if it is not required to be used as a business card for the appearance. For example, the rectangular predetermined area as shown in FIG. 4 may be set at the four corners, and when the long side and the short side of the predetermined region 4 are divided into a plurality of the cut grooves 3, the cut grooves 3 are formed as shown in FIG. It may not reach the outer periphery of the predetermined area 4.
[0029]
The cut groove 3 may not reach the back surface 1b of the base material, which is the boundary between the coating layer 22 and the base material 1 on the back surface side.
[0030]
The predetermined areas 4 to 41 may be standardized by a size other than a business card size, for example, the size of a public postcard, or may not be set to a standardized size, and need not be divided or rectangular. Nor. Further, a plurality of predetermined areas 4 may be set on the sheet S.
[0031]
For example, as shown in FIG. 5, a configuration may be considered in which two predetermined regions 4 having a shape in which a part of a rectangle protrudes from the sheet S are set, and the cut groove 3 is not provided inside the predetermined region 4. It is done.
[0032]
Further, printing on the sheet S may be performed using a device other than a printer, and predetermined contents may be entered by handwriting instead of printing.
[0033]
In addition, the present invention is not limited to the above illustrated example, and various modifications can be made without departing from the spirit of the present invention.
[0034]
【The invention's effect】
