Abstract

PROBLEM TO BE SOLVED: To improve a forgery preventive effect by providing a watermark partly on a postcard obtained by folding a plurality of folding one side parts connected by a folding line and press bonding them. SOLUTION: A sheet 1 of the postcard is formed of three folding piece parts connected by a plurality of folding lines 3a, 3b, and formed with watermarks 2a to 2c at the respective piece parts. The piece parts of both sides are folded on a central folding piece parts to form a watermark 2 expressing one design (e.g. a character of a 'watermark') by the watermarks 2a to 2c. Then, the expressed design is not limited to the character, but may be combined with a graphic form or the character and the graphic form. Since the watermark 2 can express the design having meaning only after folding but does not mean how the watermarks 2a to 2c are disposed in a press bonded state, its forgery preventive effect can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crimped postcard that is obtained by folding a sheet to which a pressure-sensitive adhesive is applied and pressing the folded paper, and more particularly to a crimped postcard having a watermark.

[0002]

^2. Description of the Related Art A pressure-bonded postcard is printed on paper coated with a pressure-sensitive adhesive (adhesion conditions of about 120 to 150 kg / cm ² ) over the entire surface and then folded and pressed with the printed portion inside.

[0003] Also, since such crimped postcards are often used for confidential use, they are often provided with forgery prevention means.
Heretofore, it has been common practice to print an imprint pattern or a tint block as a forgery prevention means.

[0004]

However, the conventional crimped postcard has the following problems. (1) In the conventional forgery prevention method, forgery can be relatively easily performed by copying with a copying machine or printing with a simple printing machine. (2) When the adhesive is applied to the entire surface, it is difficult to peel off,
For this reason, a corner cut is provided, or a release agent is applied to the end portion, but the work of providing these peel-off portions is complicated.

[0005] A main object of the present invention is to provide a crimped postcard that is more difficult to forge in view of the above problems.

Another object of the present invention is to provide a crimped postcard having a simpler peel-off portion.

[0007]

The structure of the present invention to achieve the above object is as follows.

[0008] That is, the present invention relates to a watermarked crimped postcard in which a plurality of folded pieces connected by a fold line are folded and crimped, and a watermark portion is partially provided.

A further feature of the watermarked pressure-bonded postcard of the present invention is that the watermark portion is provided on at least two or more folded pieces, and the watermark portion forms one picture when folded. "The watermark portion is provided on at least two or more folded pieces, and the watermark portion constitutes one picture in a state where it is peeled and developed.""A single pattern is straddled over one fold piece portion", "the watermark portion is provided on two fold portion portions that are crimped to each other, and the watermark portion forms a part of the crimp surface. In the state of peeling and development, a single pattern is formed across the two folded pieces. "
That the watermark portion is provided on two fold portions that are pressed against each other, and the watermark portion and the non-watermark portion of the two fold portions are disposed with respect to a fold line connecting the two fold portions. That the watermark portion is provided on at least two or more folded pieces, and that the watermark portion is disposed so as to overlap in a folded state. "The watermark portion is provided on at least two or more folded portions, and the watermark portion is a linear shape whose position in the vertical direction is slightly shifted by each folded portion." Is a white watermark portion formed of a concave portion having a small paper thickness, '' and `` the watermark portion is configured of a white watermark portion formed of a concave portion having a small paper thickness and a pseudo watermark portion formed by applying a transparent ink. Is included. " .

According to the watermarked postcard with the present invention, forgery by copying, printing, or the like is not possible.
When data is printed on the watermark portion, it can be easily found even if another data is pasted and falsified on the original data.

[0011] In the watermarked pressure-bonded postcard of the present invention,
It is also preferable that the watermark portion is a white watermark portion formed of a concave portion having a small paper thickness, and the watermark portion is provided at a corner or an edge of a folded portion serving as a peeling start portion. That is, such a watermark portion can also function as a peel-off portion.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION A pressure-sensitive postcard according to the present invention is usually coated with a pressure-sensitive adhesive on the entire surface of a sheet and adhered to the entire surface. Conventionally known pressure-sensitive adhesives can be used as such pressure-sensitive adhesives. For example, natural rubber, acrylic copolymer, NB
An adhesive mainly composed of synthetic rubber such as R and SBR can be used.

[0013] In the crimped postcard of the present invention, a watermark portion is provided. As a method of forming such a watermark portion, a conventionally known method can be used. For example, a method of forming a watermark into a white watermark by reducing the thickness of a portion to be a watermark at the time of papermaking or printing a picture or the like simultaneously with a wax is included. A method of increasing the light transmittance of a sheet by printing a transparent ink to form a pseudo watermark portion can be used.

Hereinafter, embodiments of the crimped postcard of the present invention will be described with reference to the drawings, but needless to say, the crimped postcard of the present invention is not limited to these embodiments.

FIG. 1 shows a state of peeling and development (FIG. 1A).
In this example, the whole image cannot be grasped. However, in this example, a watermark portion is provided so as to constitute one picture in a folded state (FIG. 1B).

As shown in the developed view of FIG.
Is composed of three folded pieces connected by folding lines 3a and 3b, and watermarks 2a to 2c are formed in these folded pieces, respectively.

In the crimped postcard of the present embodiment, when the folded portion and the folded portion are folded on the folded portion, as shown in FIG. 1B, one watermark portion 2a to 2c has one picture (character "watermark"). Is a watermark unit 2. Although the same applies to the following embodiments, the above-mentioned pattern formed by a combination of a plurality of watermark portions is not limited to a character, and may be a figure, a combination of a character and a figure, or the like.

As described above, the watermark portion of the present example is not folded until a picture having a meaning is formed only when folded, and how the watermark portion is arranged on each folded portion when folded and pressed. Without knowing, an extremely high forgery prevention effect can be obtained.

FIG. 2 shows that the whole image cannot be grasped in the folded state (FIG. 2B), but the watermark portion is formed so as to constitute one picture in the peeled and unfolded state (FIG. 2A). This is an example in which is provided.

In the crimped postcard of the present embodiment, the watermark portion 2 provided on the folded piece portion connected by the folding lines 3a and 3b is provided.
“a” to “2c” constitute one picture (character “watermark”).

As described above, in the watermark portion of this embodiment, a picture having one meaning is formed in a state of being separated and developed, and
In the state of being folded and crimped, it is not known how the watermark portion is arranged on each of the folded pieces, and an extremely high forgery prevention effect can be obtained.

FIG. 3 shows an example in which a watermark portion is provided so as to straddle two folds in a peeled and unfolded state to constitute one picture.

In the crimped postcard of the present embodiment, the watermark portions 2b and 2c provided on the folded portion connected by the folding line 3b and the watermark portions 2b and 2c form one picture over the folded portion.

Also in such a pressure-bonded postcard of this embodiment, the forgery prevention effect by the watermark portion is obtained. Particularly, when the postcard is applied to a postcard that is used as a reply postcard of a round-trip postcard or a piece of paper cut out like a voting contact form Can be effective means for preventing forgery. That is, when the folded portion separated by the folding line 3b is used again, the authenticity of the folded portion can be determined by comparing the watermark pattern provided on each sheet with the original.

FIG. 4 shows a state in which a part of the crimping surface is peeled and developed on two folded pieces to be crimped to each other (FIG. 4 (b)).
This is an example in which a watermark portion is provided so as to form one picture over two folded pieces.

In the crimped postcard of the present embodiment, the watermark portions 2a and 2b provided on the folded portions connected by the folding line 3 and the watermark portions 2a and 2b are straddled only when the predetermined direction and length are peeled off. Therefore, since one pattern (the character "") is formed, an extremely high forgery prevention effect can be obtained.

FIG. 5 shows an example in which a watermark portion and a non-watermark portion are provided on a folded piece portion to be crimped to each other so as to be antisymmetric with respect to a fold line 3b connecting the folded pieces.

In the crimped postcard of this example, in a folded state,
The watermark portion 2b of the folded portion overlaps the non-watermark portion of the folded portion, and the non-watermark portion of the folded portion overlaps the watermark portion 2c of the folded portion. Therefore, in the folded state, the presence or absence of a watermark cannot be determined. A high forgery prevention effect is obtained. Also, there is no unevenness in the compression strength due to the presence of the watermark.

FIG. 6 shows an example in which watermark portions 2a to 2c are provided on the folded pieces to overlap each other in a folded state.

When the crimped postcard is folded in three or more, for example,
It becomes difficult to recognize the difference in light transmittance between the watermark portion and the non-watermark portion, and it becomes difficult to visually recognize the presence or absence of the watermark. However,
As in the crimped postcard of this example, the difference in light transmittance between the watermark portion and the non-watermark portion in the folded state can be increased by making the watermark portions of the folded portions overlap in the folded state. , The presence of the watermark portion can be visually recognized, and the authenticity can be easily determined.

FIG. 7 shows an example in which linear watermark portions 2a to 2c whose positions in the top and bottom directions are slightly shifted are provided in the folded portion.

In the crimped postcard according to the present embodiment, since a slightly linear rectilinear watermark portion is formed in each folded piece portion, the positional deviation of each watermark portion is hardly visually recognized, and an extremely high forgery prevention effect is obtained. Can be

FIG. 8 shows, as watermark portions, a white watermark portion formed of a concave portion having a small paper thickness, and a pseudo watermark portion obtained by printing transparent ink containing wax or the like to increase the light transmittance of the sheet.
This is an example in which different types of watermarks are provided.

In the crimped postcard of this example, since two types of watermarks, that is, the white watermark portion 4 and the pseudo watermark portion 5, are used in the folded portion, it is difficult to forge the watermark itself, and an extremely high forgery prevention effect is obtained. can get.

FIGS. 9 and 10 show an example in which a white watermark made of a concave portion having a small paper thickness is provided at an edge or a corner of a folded portion serving as a peeling start portion.

FIG. 9 shows a two-fold pressure-bonded postcard, in which a white watermark portion 4 is provided at an end of a folded piece. FIG. 10 shows a three-fold crimped postcard, in which a white watermark portion 4 is provided at each of the folded portion and the corner.

Since the adhesive strength with the opposing surface is slightly weakened in the white watermark portion 4 composed of the concave portion, the white watermark portion 4 at the edge or corner can be used as a peeling portion when peeling and developing. . For example, in FIG. 10, when the folded portion is folded on the folded portion, and the folded portion is further folded on the folded portion and pressure-bonded, first, the white watermark provided on the folded portion is cut and the folded portion is cut. By peeling and developing, and then peeling and developing the folded piece portion by cutting the white watermark portion provided on the folded piece portion, the pressure-bonded postcard can be easily peeled and developed.

As described above, in the crimped postcard according to the present embodiment, the watermark portion for preventing forgery can be used as the peeling and hanging portion, and the complicated work of providing the peeling and hanging portion as in the related art can be omitted.

[0039]

The crimped postcard according to the present invention is as described above, and has the following effects.

(1) Forgery by copying, printing, etc. becomes impossible, and when data is printed on a watermark portion, even if other data is pasted and falsified on the original data, this can be easily done. Can be found.

(2) As the form of the watermark portion, one picture may be formed only in a folded state or a peeled-out state, or one picture may be formed over a plurality of folded portions. In the case where each of the folded portions is a linear shape slightly shifted in the vertical direction or a combination of two types of watermarks, ie, a white watermark portion and a pseudo watermark portion, an even higher forgery prevention effect can be obtained. Can be

(3) In the case where a watermark portion and a non-watermark portion are provided on fold pieces to be crimped to each other so as to be symmetrical with respect to a fold line connecting them, it is determined whether or not a watermark exists in the folded state. It is not possible to discriminate and an extremely high forgery prevention effect is obtained, and there is no unevenness in the compression strength due to the presence of the watermark.

(4) In the case where a watermark portion that overlaps in a folded state is provided, the presence of the watermark portion can be visually recognized even in the case of three or more folds, and it is possible to easily determine the authenticity. .

(5) In the case where a white watermark portion is provided at an edge or a corner of a fold portion serving as a peeling start portion,
The white watermark portion can be used as a peeling portion, and a complicated operation for providing a peeling portion as in the related art can be omitted.
