Abstract

PURPOSE:To continuously display information over both sheet pieces at a sender and to eliminate the separation of both the pieces even after the pieces are isolated and developed at a recipient by covering a raw sheet with transparent resin film, folding it with the transparent film inside, and applying the opposed inner sides of the pieces separably so that the separated faces after separation do not have adhesive. CONSTITUTION:The inner one side faces of folded communication sheet 1 displayed with a communication sentence, a photograph or other information on the inner face are coated on the outer face of a folded transparent resin film 2 through an adhesive layer 3 to be impossible to be separated, and the inner side faces of the folded film 2 separably adhere to each other through a quasi-adhesive layer 4. This communication sheet can be used as a main card or other mail matter. The sheet delivered to a recipient is separated from the edge of the layer 4, and developed. The developed sheet is continuously covered with the film 2 at both sides, and the separating faces of the film 2 do not have adhesive properties.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a communication sheet that can be used for postcards and other items, and a method for manufacturing the same.

[Conventional technology]

Japanese Utility Model Publication No. 49-33930 discloses a combined postcard made of two postcard-shaped pieces of paper that are releasably glued together. These combined postcards display the correspondence and other information on the inside of each piece of paper and are included in the mail. It is possible to do so.

However, in the above-mentioned combined postcard, since both pieces of paper are separate sheets, certain information, such as text, diagrams, graphs, photographs, etc., is displayed continuously across both pieces of paper on the sending and receiving side. Furthermore, even if continuous display could be made on the inner surfaces of both pieces of paper, the pieces of paper would be completely separated when peeled off and unfolded by the recipient, so the continuity of the information would be lost and it would be difficult to store or file. This was also inconvenient, and the inner surfaces of both pieces of paper could not be effectively used continuously.

In addition, in the above-mentioned combined postcard, even after the recipient side peels off and unfolds both pieces of paper or one of the pieces of paper, the peeled surface remains sticky, which causes discomfort to the recipient side and makes the recipient feel uncomfortable. It was difficult to store and file on the side.

[Problem to be solved by the invention]

Therefore, the object of the present invention is to provide a constant +)!
il can be easily displayed continuously across both pieces of paper, and even after both pieces of paper are peeled off and unfolded on the recipient's side, the continuity of the information is maintained without separating the pieces of paper. To provide a communication sheet that has no unpleasant stickiness on its peeling surface and is convenient for storage and filing.

[Technical means to solve the problem]

The communication sheet according to the present invention includes a bi-folded communication paper, a bi-folded transparent resin film that is non-releasably coated on the inner surface of each opposing side of the bi-folded communication paper, and a bi-folded transparent resin film that is coated on the opposing side of the bi-folded transparent resin film. It consists of a pseudo-adhesive layer that adheres the inner surfaces of each side to each other in a removable manner and so that the peeled surface does not have adhesiveness after peeling.

In the above, a slit may be formed along the edge of the two-folded communication paper to a depth that extends from one surface of the two-folded communication paper to the inner pseudo-adhesive layer. Further, each opposing inner surface of one side of the two-fold communication paper may be configured to have a non-adhesive area not covered with the transparent resin film along its edge. Further, the transparent resin film may be folded in two or may be irreleasably bonded at the edge thereof.

The method for manufacturing the communication sheet described above includes a step of coating raw paper with a transparent resin film, a step of folding the resin-coated raw paper in half with the transparent resin film side facing inside, and a step of folding the resin-coated raw paper in half with the transparent resin film facing inside. The inner surface of each side,
This process consists of adhering them to each other so that they can be peeled off and the peeled surfaces after peeling do not have tackiness. In addition, when manufacturing multiple communication sheets from the above resin-coated raw material paper, a step of cutting it into predetermined dimensions is added as necessary at an appropriate time after the step of coating with the transparent resin film. be done.

The bifold correspondence paper described above may be formed from computer output paper. Moreover, as the above-mentioned transparent resin film, for example, a resin film such as polyethylene, polypropylene, polyester, etc. can be suitably used. The pseudo-adhesive layer described above can be formed by applying heat and pressure treatment to the inner surface of each opposing side of a bi-folded transparent resin film, for example, depending on the physical properties, thickness, presence or absence of surface treatment, etc. of the resin film used. I can do something. In order to obtain the required pseudo-adhesive layer, an anti-blocking agent, a coupling agent, etc. may be added to the resin film, or a surface treatment such as plasma treatment or corona discharge may be applied. You can also

Incidentally, the inner surface of a postcard-sized raw paper (57.5 kg coated paper) was coated with a polypropylene film (thickness 45 μm) and a polyethylene film (thickness 40 μm) with adhesive, and the paper was folded in half and then heated using a heat roller (press). Pressure 4Kg
, paper feed speed 1.06m/m1n), heating and pressure treatment was performed at 110 to 120°C for the mask and 80 to 90°C for the latter. The desired pseudo-adhesion pattern was obtained in which the peeled surface did not have tackiness. Also, in the same way, polyethylene film (
For the case of 25μ thick), the beat roller (press pressure 4Kg, paper feed speed 2m/m1n)
When heat and pressure treatment was performed at 0° C., the required and preferable pseudo-adhesion mode was obtained.

(Function) The above-mentioned communication sheet is peeled off from the pseudo-adhesive layer portion on the recipient side, and after development, the peeled surface on each side is continuously covered with a transparent resin film.

The transparent resin film after peeling has no tackiness on its surface, improves the aesthetics of the information display surface, and protects it from external friction, pollution, moisture, etc.

In the above, if a slit is bored along the edge of the bi-folded communication paper to a depth that reaches from one surface of the bi-folded communication paper to the internal pseudo-adhesive layer, the communication sheet is cut into the part of the slit. It can be peeled off from. In addition, if the two-folded communication paper is configured to have a non-adhesive area that is not covered with a transparent resin film on the inner surface of each opposing side or along its edge, the communication sheet can be peeled off from the non-adhesive area. can do. Further, in the case of a two-fold transparent resin film or one whose edges are irremovably bonded, the film can be peeled off after the bonded portion is cut off.

In addition, the method for manufacturing the common sheet according to the present invention consists of various steps such as resin coating, folding in half, bonding by heating and pressure treatment, etc., and the individual steps are relatively simple and can be performed using conventional techniques. It is also possible for one company to adopt automation.

Incidentally, the present inventor previously discovered that, for example, Japanese Utility Model Publication No. 57-60036 and Utility Model Application Publication No. 62-92
As disclosed in Publication No. 80 tU, two resin films are bonded to each other by sandwiching a film laminate formed by peelably bonding.
[--Have you developed a fixed communication sheet or require a large amount of man-hours to sandwich the film laminate?
After the sheet is peeled off and developed, the resin film coverage breaks at the 5-fold line and becomes discontinuous, which impairs the aesthetic appearance and makes the covering function incomplete. The fold lines are covered continuously.

[Example 1] In Figs. 1 and 2, a bi-folded transparent resin film is placed on the inner surface of each side of a bi-folded communication paper 1 on which three letters, photographs and other information (not shown) are displayed on the inner surface. The outer surface of 2 is coated in a non-peelable manner via an adhesive layer 3, and the inner surface of each half of each half-folded transparent resin film 2 is peelably bonded via a pseudo-adhesive layer 4 (indicated by a boundary line). There is. The communication sheet formed in this way is, for example,
As shown in the figure, by writing the addressee 5 and sender's name 6 on the surface and pasting a stamp 7, it can be used as a postal item or other postal item.

The communication sheet delivered to the recipient is peeled off from the edge of the pseudo-adhesive layer 4 as shown in FIG. 3, and unfolded as shown in the fourth country. The unfolded communication sheet is continuously coated with a transparent resin film 2 on each side, and the peeling surface of the transparent resin film 2 does not have adhesiveness.

[Example 2] In the communication sheet of Example 1 shown in FIGS. 5 and 6, the slits 8 are formed continuously or discontinuously (like a sewing machine) along the edges of the folded communication paper 1. The slits 8 are perforated along the two-folded communication sheet 1 to a depth that reaches the internal pseudo-adhesive layer 4 from one surface of the folded communication sheet 1, as shown in FIG. By operating to open it, it can be easily peeled off from the pseudo-adhesive layer 4. Such a sleeve l-8 may be perforated along the edge of the folded communication paper 1, but at a different position from the above, for example, at a corner of the knee-folded communication paper 1 as shown in FIG. . Furthermore, in order to prevent the communication sheet from peeling off due to these natural openings, adhesive tape (not shown) is applied to the particularly continuous slits 8 on the paper 1 during the half-folding process. It may be coated in a peelable manner.

[Example 3] What is shown in FIGS. 9 and 10 is the communication sheet of Example 1, in which a transparent resin is applied to the inner surface of each opposing side of the bi-folded communication paper 1z along its edge. A non-adhesive area 9 is provided in the film 2 which is not covered.

In this communication sheet, at least a part of the edge of the folded communication paper 1 is located outside of each edge of the folded transparent resin film 2 and the pseudo-adhesive layer 4, as shown at 21C in FIG. Since it protrudes, the peeling operation is easy. Such a non-adhesive area 9 may be provided along the edge of the bi-folded communication paper 1, but at a different position from the above, for example, at the corner of the bi-folded communication paper 1 as shown in FIG. good.

", as shown in FIGS. 12 and 13, the non-adhesive area 9 is provided along the edge of the knee-folded communication paper 1 at some distance from the edge. Good too. This street (
After the 8th sheet is picked up by the recipient, it is cut along the non-adhesive area 9 as shown in FIG.
It becomes a state where it is easy to peel off as shown in Figure 0. The non-adhesive area 9 as described above may be discontinuously provided, for example, as shown in FIG. 15. It is preferable that a cutting mark 10 indicating the cutting position is not attached to the edge of the two-fold communication paper 1.

[Example 4] What is shown in FIGS. 16 and 17 is the communication sheet of Example 1, in which the two folded transparent or bright resin films 2 are joined together at the edge thereof in a non-separable manner. It has been established. The bonding portion 11 is obtained, for example, by welding the opposing transparent resin films 2 by heating them at high temperature, adhering them with an adhesive, or the like. After this communication sheet is delivered to the recipient, it is cut along the inside of the joint portion 11 as shown in FIG. 18, so that it is in a peelable state as shown in FIG. 2. Instead of providing the above-described bonding portion 11, the opposing transparent resin films 2 may be continuously integrated as shown in FIG. 19, thereby being irreleasably bonded.

It is preferable to attach a cutting mark 12 to the edge of the folded communication paper 1 to clearly indicate the cutting position.

[Example 5] The communication sheets of Examples 1 to 4 are as shown in FIG. 20 (A
) to (B). That is, as shown in FIG. 20(A), the transparent resin film 2 has correspondence, photographs, and other information (not shown) on its surface.
is repeatedly displayed on the surface of a raw material paper 13 for a plurality of F communication sheets is coated with an adhesive layer 3, and the resin-coated raw paper 13 is cut into a plurality of F- resin-coated communication sheets 1. .

Next, each resin-coated communication paper 1 is folded in half as shown in FIG. The transparent resin film 2 is heated and pressurized, and the opposing inner surfaces of each side of the folded transparent resin film 2 are bonded together via the pseudo adhesive layer 4. The above judgment will be made as necessary.
This may be performed after the resin-coated large-sized raw paper 13 is folded in half and bonded.

In addition, when manufacturing the communication sheet of Example 3, the transparent resin film 2a may be coated so that the non-adhesive area 9 is formed, and when manufacturing the communication sheet of Example 4, the sheet may be folded in two. A predetermined edge portion of the transparent resin film 2 of
1 may be formed.

The above method is particularly useful as a method for manufacturing a large quantity of communication sheets on which the same information is displayed, such as for direct mail. For this purpose, the transparent resin film 2 may be covered, folded in two, and bonded.

(Effects of the Invention) As described above, in the communication sheet according to the present invention, certain information can be easily displayed continuously across both pieces of paper on the sender side, and on the receiver side, it is possible to display certain information continuously across both pieces of paper. Even after peeling and unfolding, the continuity of information is maintained without the paper pieces separating, and there is no unpleasant stickiness on the peeled surface, making storage and filing convenient.

In addition, in the above-mentioned communication sheet, the transparent resin film after peeling and spreading does not have adhesiveness on the surface, improving the aesthetics of the information display surface and protecting it from external friction, pollution, moisture, etc. In particular, since the peeling surface on each side of the communication sheet is continuously covered with the transparent resin film including the central fold line, the above effect is further promoted.

In the above, there are cases in which a slit is bored along the edge of the bi-folded communication paper to a depth that reaches from one side surface of the bi-folded communication paper to the internal pseudo-adhesive layer, and along its edge,
If the communication sheet is configured to have a non-adhesive area that is not covered with a transparent resin film, it is easy to remove the communication sheet.

Furthermore, a transparent resin film folded in half and non-separably bonded at its edge is convenient for security because it can be peeled off after the bonded portion is cut.

In addition, in the method for manufacturing communication sheets according to the present invention, each process is relatively simple, conventional techniques can be reused, and automation can be adopted, so that the above communication sheets can be produced efficiently and inexpensively. It is particularly suitable for mass production.
