Description

  The present invention relates to a postcard making sheet in which an unsealing history remains, and in particular, to a postcard making sheet that enables a recipient to detect when transmission information is peeped in the middle of sending.

Conventionally, when personal information that is not desired to be read by another person is transmitted, a document containing the personal information is sent as a sealed letter. However, the sealed letter has been a heavy burden for companies that have to send a large amount of delivery due to the higher sending fee compared to postcards.
Therefore, a postcard has appeared that can send the transmission information in a postcard that cannot be read from the outside.
This postcard is a postcard that is sent in a postcard by applying a peelable pressure sensitive adhesive to the bonded surface, printing personal information on the adhesive surface, and then bonding the adhesive surfaces together with a special crimping device. It has become.
The person who receives the postcard peels the bonded surface at the crimped boundary and reads the personal information.

However, there have been incidents where personal information printed on this postcard was peeped in the middle of transmission and used illegally. If the printed personal information is information related to a password such as a card, the password must be changed immediately.
Therefore, a secret information concealment sheet is provided that can be detected even when another person peels the cover sheet and peeks out (see, for example, Patent Document 1).

JP 2003-72264 A

  According to the secret information concealment sheet of the invention described in Patent Document 1, a circular opening detection unit that is close to the outer edge of the A piece integrated with the B piece via the sewing machine wire 1 and has intermittent cuts 3a and 3b around it. 2a, 2b are provided, adhesive adhesives 4a, 4b are provided on the part facing the opening detection parts 2a, 2b on the back of the B piece, and opening detection parts 2a, 2b on the back of the A piece are provided. The adhesive weak adhesive 5 is applied to the other surface, and the A piece is bent by the sewing machine wire 1 and bonded to the back surface of the B piece.

However, the confidential information concealment sheet of the invention described in Patent Document 1 forms a sticky strong adhesive and a sticky weak adhesive on the bonding surface in order to leave the opening history of the concealment sheet as described above. There must be.
Accordingly, an object of the present invention is to provide a sheet for making a postcard in which an unsealing history remains using a peelable pressure-sensitive adhesive formed on a pressure-bonded postcard as it is.

  In order to achieve the object, the sheet for postcard production according to the present invention has a portion to be folded at a position that bisects the long side of a rectangular paper piece, and is a pressure-sensitive material that can be peeled over the entire surface of the paper piece. A sheet for postcard preparation in which an adhesive is formed, wherein an opening planned portion is formed at one corner near the short side of the paper piece, and an opening check is performed on the pressure-sensitive adhesive forming surface in the vicinity of the opening planned portion. A pattern is formed, and at least the unsealing check pattern forming surface side of the fold planned portion is formed with a 5 to 15% uniform halftone dot by printing on the pressure sensitive adhesive forming surface excluding the inside of the unsealing check pattern, A cut is formed in a half cut shape on the periphery of the opening check pattern.

By the postcard-producing sheet of the present invention,
1) Personal information is printed on the pressure-sensitive adhesive forming surface of the postcard-preparing sheet, the pressure-sensitive adhesive surfaces are pasted together, sent, opened by a person other than the recipient, re-pressed, and re-pressed When the recipient is delivered to the recipient, the recipient opens the unsealed portion, and since the adhesive strength is different at the portion of the unsealed check pattern, there should be resistance, but it will be fraudulent in the middle of shipping because it will peel off without any resistance. Can detect the possibility of the occurrence of defensive measures and take defensive measures.
2) Those who try to cheat do not know that the postcard has “open check” measures because no cuts are visible on the outside of the postcard body.
3) Since the area of the halftone dot to be printed can be set between 5 and 15%, and further, the halftone dot can be selected to be printed on one side or both sides of the postcard laminating surface. The peel strength and the peel strength of the opening check pattern portion can be adjusted.
4) Postcard creation costs can be reduced.

Hereinafter, the postcard-producing sheet of the present embodiment will be described with reference to the drawings.
FIG. 1 is a diagram for explaining an example of a postcard making sheet according to the present embodiment, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is an unsealing check pattern when unsealing from an unsealing portion. FIG. 4 is a diagram for explaining an example of a conventional crimping postcard.

With reference to FIG. 1, an example of a postcard making sheet according to the present embodiment will be described.
The sheet for postcard preparation 1 of the present embodiment has a scheduled folding portion 11 at a position where the long side of a rectangular paper piece is divided into two equal parts, and is a pressure-sensitive adhesive (hereinafter simply referred to as “peelable”). (Also called pressure sensitive adhesive) 2 is formed. Further, an opening scheduled portion 12 is formed at one location of the short side corner of the paper piece, an opening check pattern 13 is formed on the pressure-sensitive adhesive forming surface in the vicinity of the opening expected portion 12, and the opening check pattern 13 5 to 15% of uniform halftone dots 4 are formed by printing on the pressure-sensitive adhesive forming surface excluding the inner side.
A cut (not shown) is formed in a half cut shape on the periphery of the opening check pattern 13.

  Personal information addressed to the recipient is printed as transmission information 3 on the surface of the postcard-preparing sheet 1 on which the pressure-sensitive adhesive 2 is formed. Is printed.

A perforated cut may be formed in the planned folding portion 11 so as to be easily folded.
The triangular portion surrounded by the dotted line and the other two sides of the planned opening portion 12 shown in the figure may be printed in a solid color with dark ink so that it is easily noticeable.
A short side corner (not shown) on the opposite side to the planned folding portion 11 to be bonded to the planned opening portion 12 is corner-cut so that the solid portion can be seen when bonded.
On the destination information print surface in the vicinity of the corner cut portion, “Please open from here” or the like is printed.

Further, as described above, the halftone dots 4 can be formed on the entire surface except for the inside of the opening check pattern 13 on the left side (the side on which the opening check pattern 13 is formed) of the planned folding portion in FIG.
The halftone dots 4 are arranged at an appropriate pitch by offset printing, so that the area ratio of the portion where the halftone dots are printed and the portion not printed is changed from “5:95” to “15:85”. Printing is performed so that the area ratio is 5 to 15%.
The above-mentioned pitch is usually the distance between the centers of adjacent halftone dots, and in the case of fine paper, printing is performed at 1/80 to 1/120 inch.
The halftone dots 4 may be printed with colored ink that does not make it difficult to read the transmission information 3 by printing, or may be printed only with colorless medium.

The area ratio of the above-described halftone dots 4 depends on the adhesive strength of the pressure-sensitive adhesive used. When the adhesive strength is high, the area ratio of the halftone dots is increased, and conversely when the adhesive strength is low, Reduce the area ratio.
In addition, when the pressure-sensitive adhesive has a high adhesive strength, halftone dots can be printed on both sides of the planned folding portion. Conversely, when the pressure-sensitive adhesive is low, halftone dots can be printed only on one side of the planned folding portion. .

With reference to FIG. 2, the AA line cross section of FIG. 1 is demonstrated.
As described with reference to FIG. 1, the sheet for postcard preparation is folded and pressure-bonded so that the pressure-sensitive adhesive forming surfaces overlap each other at the planned folding portion, and as shown in FIG. , Pressure sensitive adhesive 2, halftone dot 4 other than opening check pattern 13, halftone dot 4, pressure sensitive adhesive 2, and sheet base material 10 are laminated in this order.
In the lower sheet base material 10 in the drawing, cut in a half cut shape (without passing through the sheet base material 10 from the pressure sensitive adhesive side of the lower sheet base material 10) at the periphery of the opening check pattern 13 130 is formed.

With reference to FIG. 3, the state of the opening check pattern part at the time of opening from an opening part is demonstrated.
When the upper and lower sheet base materials 10 shown in FIG. 1 are opened at the boundary where the pressure-sensitive adhesive 2 is bonded, the halftone dot printing portion is peeled in a state where the adhesive force of the pressure-sensitive adhesive is weakened by the halftone dots 4.
When the opening check pattern 13 is reached, the halftone dot 4 is formed only on one side of the opening check pattern 13 or not formed at all, so that the adhesive strength is larger than the portion other than the opening check pattern 13. ing.
As a result, although depending on the adhesive strength of the set pressure-sensitive adhesive, the base material 10 is broken from the portion of the cut 130 in the shape of the opening check pattern 13, and is adhered to and peeled off from the upper sheet base material 10.
It can be seen that the postcard once peeled off at the opening portion is peeled off halfway because the portion of the opening check pattern 13 is not repaired even if it is applied again for repair.

With reference to FIG. 4, an example of a conventional crimping postcard will be described.
FIG. 4A is a view of a conventional crimped postcard 100 as viewed from the destination information printing side.
An unsealed portion 120 is displayed on the destination information printing surface, and although not shown in the figure, a display such as a dotted line cut or printing is made.
FIG. b shows a cross section along line BB in FIG. The crimping postcard 100 is folded at the planned folding portion 101 and is bonded and integrated on the pressure-sensitive adhesive 20 forming surface with the transmission information 30 inside.

When peeled off by the opening portion 120, the state shown in FIG. C is obtained, and the transmission information 30 can be read. A person who acts illegally folds the pressure-sensitive adhesive surface 20 inward again at the planned folding part 101, and returns to the original pressure-sensitive postcard shown in FIG.
That is, the recipient cannot detect the transmission information 30 even if the transmission information 30 is peeped in the middle of the transmission.

With reference to FIG. 2, an example of the material used for the postcard preparation sheet of this embodiment is demonstrated. However, the following materials are not concerned.
A material selected from 127.9 g / m ² high quality paper, medium quality paper, coated paper, bleached kraft paper, recycled paper and the like is used for the sheet base material 10 of the postcard production sheet 1.
As the peelable pressure sensitive adhesive 2, a pressure sensitive adhesive which can be peeled by adding fine particles in a rubber based adhesive or an acrylic adhesive is used. Peelable pressure-sensitive adhesives are also called “cold seal adhesives”, “pseudo adhesives”, etc., and are distinguished from ordinary adhesive adhesives and adhesives that can be repeatedly re-peeled and re-applied. The “peelable pressure-sensitive adhesive” as used herein can be peeled after being pressure-bonded, and once peeled off, it cannot be reapplied under normal pressure.
As the dot printing ink, a commercially available offset ink for ultraviolet curing is used.

(Example)
The sheet base material 10 was 127.9 g / m ² high quality paper.
As the pressure-sensitive adhesive, a pseudo-adhesive obtained by adding fine particles to a rubber-based adhesive main agent was used.
UV drying type offset ink (colorless medium) was used for printing.
On the halftone dot printing surface, 10% halftone dots were printed uniformly at a line number of 80 lines / inch.
For the measurement of the adhesive strength, a combination of a sheet with a halftone dot printed on the pressure-sensitive adhesive-formed surface and a plain sheet without a halftone dot was pasted together with a special sealer, and the peel strength was compared. The peel strength was compared using a tensile strength tester and measured values using a specimen having a sample width of 50 mm.
Measurement result (measured value is the average value of each 10 measured points <rounded down after the decimal point>)
Bonding of halftone dot printing surfaces: 40g
Bonding of halftone dot printing surface and non-ground: 80g
Bonding between flat surfaces: 200 g (paper peeling occurs)
From the above results, it was found that the detection by the opening check pattern is effective.

  The postcard using the postcard preparation sheet of the present invention is used as a postcard sent from a financial institution, a life insurance company, a credit card company, a department store, or the like.

It is a figure for demonstrating an example of the sheet | seat for postcard preparation of this Embodiment. It is the sectional view on the AA line of FIG. It is a figure for demonstrating the state of the opening check pattern part at the time of opening from an opening part. It is a figure for demonstrating an example of the conventional crimping postcard.
