Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to reciprocal postcards. More specifically, the present invention relates to a reciprocal postcard capable of concealing a large amount of information because the sheets folded in multiple layers can be peeled off and cannot be re-adhered after being peeled off, although the appearance is a normal reciprocal postcard.

In recent years, in postal matters such as postcards, information in which a large amount of information can be mailed by folding or stacking leaf pieces on which a plurality of pieces of information are written is widely used. As such an information communication body, there is, for example, Japanese Unexamined Patent Publication (Kokai) No. 3-162996, "Postcard and reciprocal postcard with secret postcard".

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The postcard described in No. 6 is a laminated sheet having a four-layer structure in which a heat-sensitive adhesive layer is provided on both outer sides of a two-layer transparent film that is adhered in a peelable manner and cannot be re-adhered after peeling (hereinafter referred to as pseudo-adhesion) ( Hereinafter, a pseudo-adhesive sheet) is inserted between the facing paper pieces of the folded postcard paper material, and the paper pieces are releasably integrated by a heat-sensitive adhesive method. According to the above-mentioned invention, four paper pieces connected laterally via a fold line are folded into a W-shaped cross section, and three continuous paper pieces are Z-folded to be peelably integrated as a postcard, and the remaining one paper piece is for reply. A reciprocal postcard with a secret postcard as a postcard is described. This reciprocal postcard with secret postcard can transmit an overwhelming amount of information compared to the conventional reciprocal postcard.

However, the current postal law requires that a reply postcard must be connected to a piece of paper which is regarded as the body of a folded postcard as a standard for a return postcard. That is, the main body of the Z-postcard is currently regarded by the Postal Law as the central piece of the three pieces. Therefore, the reply postcard must be connected to the central piece of paper at the position indicated by the alternate long and short dash line as shown in FIG. Such a structure cannot be formed by simply folding four connected pieces of paper. At present, a postcard with a W-shaped cross section is not allowed. In the Postal Law, the weight of a postcard is 4g-1
It is defined as 0g. Therefore, as the number of pieces of paper increases, the weight of one piece of paper decreases as the number of pieces of paper increases, and thin paper must be used as a whole. In this case, in the above-mentioned reciprocal postcard with a postcard, the reply postcard composed of one piece of paper becomes an extremely thin piece of paper, which easily causes show-through of printing or damage such as tearing. Further, the reciprocal postcard with the private postcard is manufactured by a long continuous form paper having transfer holes on both sides of the paper piece. However, as an apparatus for folding such a paper in various forms, there is only an angle for Z-folding or S-folding 3 pieces of paper in addition to folding 2 pieces of 2 pieces, and a new large scale is required for W-folding of 4 pieces of paper. Need folding device.

The concealment information 17 is written on the back surface of the fourth leaf piece 4. The transfer hole 9 for the second sheet S2
Is finally cut and removed along the cut line 10 (not actually displayed). This second sheet S2 is also a long (hereinafter referred to as a second long sheet) -like sheet that is connected in plural vertically (vertically) in FIG. 2A at the manufacturing stage, but in the present embodiment, it is described as a unit sheet. To do.

The first sheet S1 and the second sheet S2 are the first
The front surface of the leaf piece 1 and the back surface of the fourth leaf piece 4 are aligned by the transfer holes 9 and completely adhered to each other in a non-separable manner to form a third sheet S3 as shown in FIGS. As described above, the third sheet S3 is also actually made up of a plurality of long sheets connected in the longitudinal direction (hereinafter referred to as the third long sheet), and is provided between the upper and lower unit sheets that are wound into a roll or are connected. The cut sewing machine (not shown) is folded and stored in a bellows shape.

As shown in FIG. 8, the pseudo-adhesive sheet G has various resins 31 releasably laminated on one surface of a support 32 by a melt extrusion method or a coating method, and a heat-sensitive adhesive layer 33 is formed on both outer sides thereof. What is formed can be adopted. As the support 32, for example, polyethylene terephthalate type, polypropylene type, acetate type, polycarbonate type or the like can be applied. The various resins 32 and the heat-sensitive adhesive layer 33 are made of polyethylene, polypropylene, EVA,
EEA type, EAA type, ionomer type, methacrylic resin type, polyamide type, acrylic type, poly-4-methylpentene-1 type, polyvinyl chloride type, polyvinylidene chloride type, thermoplastic elastomer type, etc. It is applicable and various known additives may be mixed. When the pseudo-adhesive sheet G is sandwiched between the leaf pieces and subjected to heat / pressure treatment, the heat-sensitive adhesive layer 33 shown in FIG. 8 melts and adheres to the sheet surface, and the leaf pieces can be separated via the pseudo-adhesive portion 34. Unify. After that, when each leaf piece is peeled off, peeling is performed from the pseudo-bonded portion 34 having a weak adhesive force. The heat-sensitive adhesive layer 33 may be replaced with a pressure-sensitive adhesive layer or an adhesive layer.

Next, a method of manufacturing a reciprocal postcard according to the present invention will be described with reference to FIG. The third long sheet (third sheet S3 is folded in a bellows shape) installed in the stocker 20 at the lower left of the drawing is folded in the Z-folded state at the normal angle 21. At this time, the fifth leaf piece 5 of the second sheet S2 is in a free state (see FIG. 3), but as shown in FIG. 4 (A), the first leaf piece 1, the fourth leaf piece 4, and the fifth leaf piece 5 together. Since it is folded as it is, it can be easily folded like a normal Z-fold. And then transported to the downstream process on the right side,
The pseudo adhesive sheet G fed from the upper and lower rolls is shown in FIG.
As shown in (A), it is inserted between the opposing surfaces of the back surface of the fifth leaf piece and the front surface of the second leaf piece and between the opposing surfaces of the back surface of the second leaf piece 2 and the back surface of the third leaf piece, respectively, and folded in the state of FIG. . Further, in the downstream process on the right side, the third sheet S is moved by the slitter 22.
The transfer holes 9 on both sides of the sheet 3 are cut and removed from the cutting line 10, and the die cutting roller 23 on the right side further cuts the third sheet S3 in the vertical direction. Figure 7 at this stage
As shown in FIG. 5, the pseudo adhesive sheet G is folded in the inserted state. Then, as a final step, the pseudo adhesive sheet G is heated and pressed by the heat roller 24.
Is heat-sensitively completely adhered to each sheet surface and integrated so as to be peelable as a whole. The completed reciprocal postcard is discharged to the belt conveyor 25 at the right end and stocked.

In this embodiment, the means for feeding out the third sheet S3 folded in a bellows shape from the stocker 20 is illustrated, but other means such as feeding out the third sheet S3 wound in a roll may be used. Absent. Although the slitter 22 is used as a method for cutting and removing the transfer hole, cutting and removal can be performed without the slitter by cutting the cut line 10 into perforations. Furthermore, although the die-cut roll 23 is illustrated as an example for cutting the third long sheet in the vertical direction, other means such as a rotary cutter may be used. Also, heating
Although the heat roller 24 is exemplified in the pressing step, other means such as a combination of a heater panel and a pressing roller may be used. In FIG. 6, the steps are arranged in the order of the slitter 22, the die-cut roll 23, and the heat roller 24, but the manufacturing method of the present invention is not limited to this order. For example, the heat roller 24 may be arranged downstream of the slitter 22 and the die cutting roll 23 may be arranged as the final cutting step, or the heat roller 24, the die cutting roll 23, the slitter 22 or the die cutting roll 23, the heat roller 24,
The slitter 22 may be arranged in this order.

The reciprocal postcard manufactured in this manner is posted as a normal reciprocal postcard. Then, the recipient of the reciprocal postcard is the fifth leaf piece 5 and the second leaf piece 2 as shown in FIG.
The second leaf piece 2 and the third leaf piece 3 can be peeled off from the pseudo-adhesive portion 34 of the pseudo-adhesive sheet G and opened. And each concealment information written inside each leaf piece can be visually recognized through the transparent film laminated with the pseudo adhesive sheet G. Next, the recipient fills in the prescribed part of the reply postcard with the answers to the questionnaire, etc., and the matters to be contacted stated in each concealed information, and then, as shown in FIG. 5 (B).
As shown in FIG. 6, the reply postcard is cut off along the folding lines 6 and 8 and only the reply postcard is posted. It should be noted that each concealment information is not limited to personal information printed by a printer or the like, and may include advertisements or advertisements that do not require much confidentiality. Also, advertisements, advertisements, and personal information may be mixed.

In this embodiment, the pseudo-adhesive sheet G is used as the pseudo-adhesive means. However, as the pseudo-adhesive means, application of a pseudo-adhesive medium made of a pseudo-adhesive resin can be adopted. The application of the pseudo adhesive medium is to form a pseudo adhesive film on the surface to be pseudo adhered and replace the pseudo adhesive sheet G. For example, the first long sheet or the second long sheet,
Further, at any stage of forming the third long sheet, a pseudo adhesive resin is formed on the surface of the second leaf piece 5 and the back surface of the fifth leaf piece 5 and the back surface of the second leaf piece 2 and the third leaf piece 3 which are pseudo-adhesive surfaces. The adhesive medium is applied by a coating method or the like to form a resin film. The resin coating does not necessarily have to cover the entire surface to be pseudo-bonded, and the surface of the paper may be partially exposed in a discontinuous pattern. Further, the surface state may be such that it penetrates between the paper fibers and is mixed with the paper fibers. The timing of application may be performed before printing, printing or processing all information, or at an intermediate stage before the completion of printing, printing and processing all information. It may be performed at the final stage after the completion of printing or printing and processing.

In the reciprocating postcard of the present invention, the width of each leaf piece can be freely changed. For example, as shown in FIG. 10 (A), the width of the fifth leaf piece 5 may be made narrower than the width of the second leaf piece 2 so that the fifth leaf piece 5 slightly enters the inside. Similarly, as shown in (B), the width of the third leaf piece 3 is made narrower than the width of the second leaf piece 2,
You may let it go in a little. FIG. 10 (B)
In this case, the other transfer hole 9 that has already been cut off in the figure is cut and removed in advance by an interstacker (not shown) or the like before being folded at an angle. Therefore, the downstream process after folding has to be transferred only by the transfer hole 9 on the reply postcard side, but since the reply postcard is made up of two leaf pieces bonded together, it is thick and heavy and relatively strong, so it is extremely processed. It is easy to lose. Further, the reply postcard may be folded back in the opposite manner to that shown in FIG. Further, any of the pseudo-adhesive surfaces may be completely adhered by, for example, a double-sided adhesive sheet to provide a non-separable opposing surface.

[0018]

Since the return postcard of the present invention complies with the regulations of the Postal Law, it can be mailed at a normal return postcard fee. In addition, since the thickness and weight of the reply postcard are moderately increased, damage due to show-through or tearing of the print does not occur, and even in the manufacturing stage, the transfer hole is reinforced and durable when it is transferred only by the transfer hole on the reply postcard side. Therefore, processing can be easily performed. Furthermore, the folding form of the long sheet including the reply postcard is W
Since it is not a fold, it is a Z fold that is normally used in the current situation, so various printing and printing of information on the printer and the processing method of folds can be handled with the current equipment, and a dedicated equipment corresponding to a large W fold is newly added. It is possible to save the labor and cost of manufacturing.
