Description

The present invention relates to a reciprocal postcard and a manufacturing method thereof. More specifically, the present invention relates to a reciprocal postcard having an outgoing postcard capable of transmitting a much larger amount of information in a concealed state by stacking a plurality of leaf pieces in a peelable manner, and a method for manufacturing the same.

Conventionally, there is a “reciprocal postcard” described in JP-A-11-286192 as a reciprocal postcard having an outgoing postcard in which a plurality of leaf pieces are detachably stacked.
This is a reciprocal postcard in which a forward postcard and a reply postcard are integrated, and there is an address, correspondence, etc. on both the front side and the back side of the postcard body, such as “postcard”. The first and second attachment pieces that can be described are configured to be in close contact with each other in a peelable manner.

Japanese Patent Laid-Open No. 2003-118273 discloses a “multilayer postcard manufacturing method” as a method for manufacturing a reciprocating postcard having the same configuration.
This is a postcard-sized sheet of paper that is connected to the four sides of a sheet of paper. Applying an adhesive that can be peeled after adhesion to the entire surface of four of the sheets, pressing it after pressing it and pressing it. One side is cut.

JP 11-286192 A JP 2003-118273 A

  The reciprocating postcard according to the above-mentioned Patent Document 1 applies a sheet of paper with five leaf pieces connected or a sheet with three leaf pieces and two leaf pieces connected to each other, and applies the respective adhesives to the peelable and non-peelable surfaces. Furthermore, it is necessary to integrate after performing complicated folding processing and superposition processing.

  By the way, the complicated folding process and the overlaying process as described above cannot be performed if sheet cutting type sheets such as offset printing are used and the cutting process, the folding process, the integration process, and the like are performed in separate processes. However, in the case of a printing method such as business form printing or rotary printing corresponding to the production of a large lot, it is impossible to cope with the complicated folding process and overlay process. This is because the business form printing and the rotary printing use a long sheet, so that the type of folding is limited.

  That is, in business form printing or the like, since a continuous long sheet is folded along the flow direction, it is not unreasonable to fold it into a simple double fold or a Z-shaped (S-shaped) cross section. . However, when the long sheet is rolled up or is folded into four or more, it is impossible to complete the folding process at once because of its structure, and many processes and dedicated systems are required even if folding is performed.

  Further, if adhesives having different properties are separately applied to the peelable planned surface and the non-peelable planned surface, the complexity further increases in addition to the folding step. If it is unavoidable to cut a long sheet and process it into a sheet, processing can be performed in the same way as in offset printing, but the extra cutting process increases, and business form printing that uses a long sheet is possible. The meaning is lost and the meaning is lost.

  Therefore, a method for producing a reciprocating postcard disclosed in Patent Document 2 is conceivable as a method for compensating for the above-described drawbacks by reducing the number of leaf pieces. According to this manufacturing method, since there is no non-peelable surface, the adhesive to be applied is only a pressure-sensitive pseudo-adhesive. However, as described above, the folding form requires a complicated folding process in which winding folding and bellows folding are mixed, which is disadvantageous in a printing method using a long sheet such as business form printing. It is no different from one round-trip postcard.

The present invention has been devised by the present applicant after intensive research in view of such problems, and can transmit a much larger amount of information than conventional round-trip postcards.

There is no particular restriction on the paper used in the reciprocating postcard of the present invention. For example, a known fine paper, matte paper, gloss paper, or the like can be suitably used synthetic paper, may be selected arbitrarily in a compatible range postal method even in basis weight.

  Further, the pseudo adhesive film sheet used in the reciprocating postcard of the present invention is a known heat-sensitive material on one surface of a base material made of a relatively strong resin such as polyethylene terephthalate, polypropylene, polyethylene, polycarbonate, acetate, nylon, etc. A three-layer structure in which an adhesive layer is formed and a pseudo-adhesive layer is formed on the other surface can be suitably used. This can be easily coated on the paper surface by thermal laminating, and after coating, it has the feature that it can be peeled off by applying pressure or pressure and heat treatment with the pseudo adhesive layers facing each other. Yes. As such a pseudo-adhesive film sheet, the product name “Postcard Film Thermal (manufactured by KDK Corporation)” is commercially available.

In addition, it is possible to use the pseudo-adhesive film sheet having a two-layer structure in which a pseudo-adhesive layer is formed on one surface of the substrate. This compound can be coated easily paper surface by dry lamination, pressing or are opposed to each other pseudo adhesive layer after coating with the features of adhering peelable by applying pressure and heat treatment Yes. As such a pseudo-adhesive film sheet, a product name “postcard film dry (manufactured by KDK Corporation)” is commercially available.

  In the method for producing a reciprocating postcard of the present invention, it is necessary to fold a long sheet continuously. First, the outermost leaf pieces among the four leaf pieces connected in the lateral direction are folded. Such a folded form is called single sleeve folding, and is a very normal form as a form in which a long sheet printed by business form printing or the like is folded by post-processing. In addition, the form in which a three-joint long sheet is folded into a Z-shaped section (S-shaped) after covering the pseudo-adhesive film sheet is also referred to as Z-folding, which is an extremely normal form. It can be carried out very easily by using a known folding angle device which is usually used in the above. Note that Z-folding is expressed as “Z-shaped (S-shaped)” in the present invention because it looks S-shaped depending on the direction of observing the cross section.

In the integration step in the method for producing a reciprocating postcard according to the present invention, for example, if the pseudo-adhesive layer of the pseudo-adhesive film sheet is responsive to pressure treatment, the main component is a pressure roller comprising a pair of metal rollers. Things can be used . If the pseudo-adhesive layer is responsive to heat and pressure treatment, for example, a heat roller whose surface is covered with silicon rubber or the like is used , or a pair of upper and lower heater panels and transport rollers are alternately arranged. In addition, a configuration in which the passing unit sheet is heated and then discharged by a pressure roller, a configuration in which the pressure roller is replaced with a heat roller, and a heater panel and a heat roller are combined can be used.

The reciprocal postcard of the present invention can be easily mass-produced by an amateur even though it has a complicated structure by a manufacturing method described later.
When the completed reciprocating postcard is opened, the surface is covered with a film sheet and deep gloss treatment is applied, so the effect of art printing etc. is doubled and each leaf piece does not separate after opening Etc. are easy, and some leaf pieces are not lost.
In addition, the amount of information transmitted increases dramatically, although it is not different from the conventional postage for postcards. In other words, it is extremely economical because the postage fee is a normal round-trip postcard fee while having an information providing capability comparable to a sealed letter.

  Furthermore, according to the manufacturing method of the present invention, although it is a complicated folding mode, it is configured in a normal folding form that can easily cope with a long sheet. It is extremely realistic and useful compared to complicated folding modes that are not realistic. In addition, for the application of various adhesives, it is only necessary to cover the pseudo-adhesive film sheet, and the coating can be easily carried out by a double-sided laminator for a normal long sheet. Realistic and useful. That is, a special apparatus is not required for carrying out the present invention, and it is very convenient because a known normal apparatus used so far may be used.

Furthermore, if you print on the address side of the long sheet, you can also print on the side that is concealed after completion of the reciprocal postcard, so you do not have to bother to print on the other side, saving you time and effort. There is no need to print twice with a single printer device or to prepare two printer devices. Therefore, when printing that requires concealment of personal information, etc., it does not take extra time and effort, and it is possible to prevent accidents such as accidental printing of other people's information twice on the front and back. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[Example 1: Basic round-trip postcard 1]
The reciprocating postcard J1 of the present invention has a third leaf piece 3, a second leaf piece 2, a fourth leaf piece 4 and a first leaf piece 1 laminated in order from the top as shown in FIGS. . The slightly narrow third leaf piece 3 is connected to the lower second leaf piece 2 via a fold line 7. The second leaf piece 2 is connected to the lowermost first leaf piece 1 via a fold line 6. Although only the fourth lobed is present alone, the said Yotsuba piece, by the pseudo adhesive film sheet G and the second lobed 2 peelably only by the pseudo adhesive film sheet G at the fold line 6 side while pseudo adhesion It is connected to the second leaf piece 2. Further, the third leaf piece 3 and the second leaf piece 2 are also pseudo-adhered by the pseudo-adhesive film sheet G so as to be peelable.

In this reciprocating postcard J1, the upper three leaf pieces (the third leaf piece 3, the second leaf piece 2 and the fourth leaf piece 4) integrated by the pseudo adhesive film sheet G constitute the outgoing postcard, and the lowermost first leaf piece 1 Constitutes a reply postcard. As shown in FIG. 1 (A), the outgoing postcard has a postage stamp field, a postal code field, and the address name of the recipient on the surface of the third leaf 3 which is slightly narrow. The word “POST CARD” described in the two-leaf piece 2 can be read. The main body of the outgoing message postcard is the second leaf piece 2 in which the wording is described.

  This reciprocating postcard J1 is peeled off between the fourth leaf piece 4 and the second leaf piece 2 and between the second leaf piece 2 and the third leaf piece 3 as shown in FIGS. This is a form in which the leaf pieces are not connected and separated after peeling.

  The recipient of this round-trip postcard J1 can peel off each piece of pseudo-adhered leaf on the outgoing postcard and check the information concealed inside through the pseudo-adhesive film sheet G. In particular, personal information is printed on the surface of the second leaf piece 2 on the side of the fourth leaf piece 4 at the same time when information such as the address name of the recipient is printed. This is because the long sheet before the production of the reciprocating postcard is the developed view shown in FIG. 6, and the surfaces of the third leaf piece 3 and the second leaf piece 2 on which the address name of the recipient is printed are arranged on the same surface side. Therefore, printing is possible at the same time. Therefore, it is not necessary to execute the printing on the back surface having the risk described above. After that, the recipient writes, for example, answers such as various questions described in the inside in the answer column provided on the reply postcard, and returns it after separating it from the cut line (folded line 6).

[Example 2: Basic round-trip postcard 2]
As shown in FIGS. 2A and 2B, the reciprocating postcard J2 of the present invention has a third leaf piece 3, a second leaf piece 2, a fourth leaf piece 4 and a first leaf piece 1 stacked in order from the top. . The third leaf piece 3 is connected to the lower second leaf piece 2 via a fold line 7. The second leaf piece 2 is connected to the lowermost first leaf piece 1 via a fold line 6. Although only the fourth lobed is present alone, the said Yotsuba piece, by the pseudo adhesive film sheet G and the second lobed 2 peelably only by the pseudo adhesive film sheet G at the fold line 6 side while pseudo adhesion It is connected to the second leaf piece 2. Further, the third leaf piece 3 and the second leaf piece 2 are also pseudo-adhered by the pseudo-adhesive film sheet G so as to be peeled off.

  The difference from the reciprocating postcard J1 of the above embodiment is that the third leaf piece 3 is almost the same as the width of the other leaf pieces. Then, as shown in FIG. 2 (A), four round windows are provided in the upper part of the postal code column of the third leaf piece 3, and are described in the second leaf piece 2 on the lower side through the round window. It is designed so that the wording of the “outbound postcard” is visible. Everything else is the same as the reciprocating postcard J1 of the above embodiment.

  In addition, about the reciprocating postcard of this invention, in order to assist peeling of pseudo adhesion surfaces, you may intentionally add the trigger used as the beginning of peeling. For example, as shown in FIG. 1 (B) in the reciprocating postcard J1 of the first embodiment, the third leaf piece 3 and the second leaf piece 2 may have a stepped portion caused by the width of the two leaf pieces as the start of peeling. If the second leaf piece 2 and the fourth leaf piece 4 are difficult to peel off, the width of the fourth leaf piece 4 may be made narrower or wider than that of the second leaf piece 2 to form a stepped portion to start peeling. Means for forming the stepped portion by manipulating the width of the leaf pieces can be applied in each embodiment of the present invention.

[Example 3: Modified reciprocating postcard]
As shown in FIGS. 3A and 3B, the reciprocating postcard J3 of the present invention has the fourth leaf piece 4, the second leaf piece 2, the third leaf piece 3 and the first leaf piece 1 laminated in order from the top. . The second leaf piece 2 is connected to the lower third leaf piece 3 via the fold line 7 and is connected to the lowermost first leaf piece 1 via the fold line 6. In addition, the 4th leaf piece 4 which exists independently is connected with the 2nd leaf piece 2 only by the pseudoadhesive film sheet G in the fold line 6 side, and pseudo-adhesively peels off with the 2nd leaf piece 2 and the pseudoadhesive film sheet G. ing. The second leaf piece 2 and the third leaf piece 3 are also pseudo-adhered by the pseudo-adhesive film sheet G so as to be peeled off.

  In this reciprocating postcard J3, the upper three leaf pieces (fourth leaf piece 4, second leaf piece 2 and third leaf piece 3) integrated by the pseudo adhesive film sheet G constitute a forward postcard, and the lowermost first leaf piece 1 Constitutes a reply postcard. As shown in Fig. 2 (A), the outgoing postcard has a postage stamp field, a postal code field, and the name and address of the recipient on the surface of the exposed fourth leaf piece 4 along the top edge. The penetrating round window is formed in four places, and it is designed so that the wording of the “forward mail postcard” written in the second leaf piece 2 on the lower side can be visually recognized through the window. The main body of the outgoing message postcard is the second leaf piece 2 in which the wording is described.

  As shown in FIGS. 3C and 4B, the reciprocating postcard J3 is peeled off between the fourth leaf piece 4 and the second leaf piece 2 and between the second leaf piece 2 and the third leaf piece 3 as shown in FIGS. This is a form in which the leaf pieces are not connected and separated after peeling.

  The recipient of this round-trip postcard J3 can peel off each piece of pseudo-adhered leaf on the outgoing postcard and check the information hidden inside through the pseudo-adhesive film sheet G. In particular, personal information is printed on the surface of the second leaf piece 2 on the side of the fourth leaf piece 4 at the same time when information such as the address name of the recipient is printed. This is because the long sheet before the production of the reciprocating postcard is the development shown in FIG. 13, and the surfaces of the fourth leaf piece 4 and the second leaf piece 2 on which the address name of the recipient is printed are arranged on the same surface side. Therefore, printing is possible at the same time. Therefore, it is not necessary to execute the printing on the back surface having the risk described above. After that, the recipient writes, for example, answers such as various questions described in the inside in the answer column provided on the reply postcard, and returns it after separating it from the cut line (folded line 6).

[Example 4: Manufacturing Method of Basic Reciprocal Postcard J1]
As shown in FIGS. 6A and 6B, the long sheet S1 used in the method for producing a reciprocating postcard according to the present invention includes a fourth leaf piece 4, a first leaf piece 1, a second leaf piece 2 and a third leaf piece. The unit sheets t1 in which the leaf pieces 3 are connected in the horizontal direction via the folding lines 5, 6, and 7 are connected in the vertical direction through the cut lines 8 provided in the vertical direction. The left-edge of the fourth lobed 4, the right side of the first lobed 1 of the left side and the third-lobed 3 marginal portion 13 having a marginal hole 12 through the cutoff line 11 are respectively provided.

  As shown in FIG. 5A, general information such as advertisements is written on the surface of the fourth leaf piece 4 that forms and displays the forward postcard after completion of the round-trip postcard. A postage stamp field, a postal code field, a recipient's address name, and the like are written on the surface of the first leaf 1 which is the main body of the reply postcard. In addition, personal information that requires secrecy (the personal information and general information may be mixed, or only the general information may be mixed) on the surface of the second leaf piece 2 concealed inside the outgoing postcard after completion of the return postcard. Have been described. Further, on the surface of the third leaf piece 3 which is the address description surface on the top surface of the forward mail postcard, in addition to the postage stamp column and the postal code column, the address name and the like of the recipient of the return postcard are described. As described above, the printing on the surfaces of the second leaf piece 2 and the third leaf piece 3 is performed without dividing the printing into two times by one printer device or using two printer devices. Since it is performed simultaneously by one printer device, a serious accident such as misinformation on another person cannot occur.

  As shown in FIG. 4B, the back of the third leaf piece 3, the second leaf piece 2, and the fourth leaf piece 4 that are concealed inside the outgoing postcard after the completion of the round-trip postcard, requires private information (personal information and general information). May be mixed, and only general information may be included). Note that the belt-like portion along the right edge of the second leaf 2 labeled “POST CARD” can be partially exposed after completion of the reciprocating postcard and read from the outside. Further, on the back side of the first leaf piece 1 which is the back side of the reply postcard, for example, a question column such as a questionnaire and an answer column for entering an answer to the question are described.

The long sheet S1 configured as described above is installed in the lower left in FIG. 5 in a state of being folded in a bellows shape and stacked in a block shape from the cut line 8 provided in the vertical direction of the unit sheet t1, for example. Is done. Although it is preferable to cut the marginal portion 13 outside the fourth leaf piece 4 in advance, it may be sent out while being cut by an inter-stacker or the like. The installed long sheet S1 passes through a folding device 20 such as a known angle, and the surface of the fourth leaf piece 4 and the surface of the first leaf piece 1 are as shown in FIGS. 7 (A) and (B). Folded into a single sleeve fold so as to face each other.

  The long sheet S1 pulled up while folding one sleeve by the folding device 20 is turned substantially horizontally by the support roller 21, and the outer marginal holes 12 are aligned with the pins of the pin tractor 22 and are downstream. Are fed into a pair of heat rolls 23a, 23b. In the pair of heat rolls 23a and 23b, the pseudo-adhesive film sheet G fed out from the rolls waiting upward and downward is drawn in and aligned with the planned pseudo-adhesion surfaces on the front and back surfaces of the long sheet S1 that passes therethrough. Then, it is coated in the state shown in FIGS. 9 (A), (B) and (C).

As shown in FIG. 8, the pseudo-adhesive film sheet G is formed with a known heat-sensitive adhesive layer 51 on one surface of a base material 50 made of, for example, biaxially oriented polypropylene, and the pseudo-adhesive layer 52 on the other surface. The three-layer structure formed with can be suitably used by a thermal laminating method using a heat roller. Moreover, you may coat | cover what consists of 2 layers of the base material 50 and the pseudo-adhesive layer 52, apply | coating an adhesive agent with a dry laminating method, without forming a heat sensitive adhesive layer.
In each drawing of this example, the pseudo-adhesive film sheet G is represented by one layer in order to avoid complication.

When the pseudo-adhesive planned surface of the long sheet S1 and the pseudo-adhesive film sheet G are passed between the pair of heat rollers 23a and 23b on the heat-sensitive adhesive layer side, the heat-sensitive adhesive layer 51 is heated. Melts and exhibits adhesiveness. The pseudo-adhesive film sheet G is firmly adhered to the planned pseudo-adhesion surface.

  The configuration of the pair of heat rollers 23a and 23b may be a heat roller that can be heated both up and down, or a heat roller that can be heated on the upper side and a backup roller that has no heating structure on the lower side. . Further, the surface of the heat rollers 23a and 23b can be a mirror-finished metal roller or silicon rubber coated surface, and the backup roller is coated with various rubbers that can absorb pressure efficiently. Can be adopted.

The long sheet S1 that has been coated with the pseudo-adhesive film sheet G on the surface to be pseudo-adhered is provided outside the third leaf piece 3 by the slitters 24a and 24b until reaching the downstream nip rollers 25a and 25b. The marginal portion 13 is excised. And it is sent out to the 2nd folding device 26 provided further downstream.
Although illustration is omitted, for example, a plurality of support rollers are added between the nip rollers 25a and 25b and the second folding device 26, and the slack is once formed in the long sheet S1 between them, and the downstream side. The tension applied to the second folding device 26 may be reduced.

As shown in FIG. 10 , the elongate sheet S1 that has passed through the second folding device 26 is pulled up to the upper support roller 27 while being folded into a S-shaped (Z-shaped) cross section, and is directed in a substantially horizontal direction. At the same time, the pins of the pin tractor 28 are aligned with the two rows of marginal holes 12 and 12 between the fourth leaf piece 4 and the first leaf piece 1 which are folded and overlapped, and are conveyed further downstream.

Then, the elongated sheet S1 folded in the state of FIG. 10 is cut off at once by the marginal portion 13 which is folded and overlapped by the slitters 29a and 29b arranged downstream. In this state, it is sent to the die cut rollers 30a and 30b further downstream.

  The long sheet S1 fed to the downstream die cut rollers 30a and 30b is cut for each unit sheet t1 from the top-to-bottom cut line 8 in the unit sheet t1 and further conveyed to the downstream integration step. As a means for cutting for each unit sheet t1, a known cutting means using a rotary cutter, a slide method, a swing method, or the like can be employed in addition to the die cut roll.

  The unit sheet t1 cut by the die cut rolls 30a and 30b is conveyed to an integration process comprising a subsequent combination of a heater panel and a heat roller. In the integration step, a pair of upper and lower conveying rollers 31a and 31b and heater panels 32a and 32b are alternately arranged along the unit sheet passing line indicated by a one-dot chain line in the drawing, and further, heat rollers 33a and 33b are provided at the final discharge portion. Has been placed. The unit sheet t1 passing between the pair of heater panels 32a and 32b is heated in a state where the pseudo adhesive layers 52 of the pseudo adhesive film sheet G attached to the planned pseudo adhesion surface are opposed to each other, and the heat roller 33a, A heating / pressurizing process is performed at 33b. As a result, the pseudo adhesive layers 52 of the pseudo adhesive film sheet G are peelably bonded and integrated as a whole, and are sequentially stacked on the stacker 34 including a conveyor on the right side in the drawing. In addition, although the structure of the said integration process is the combination of a heater panel and a heat roller, you may perform a pressurization and heat processing only with the combination of a heater panel and a pressure roller, or a heat roll.

  Although it is also a feature of the present invention, even if the unit sheet is conveyed in a state of insufficient adhesion without being sufficiently heated in the upstream coating process, it is corrected by reheating in the present integration process. Therefore, the safety regarding the quality of a product can be improved.

The round-trip postcard finished in the state of FIG. 1 is already in a state where the forward postcard and the reply postcard are folded. According to the postal law, the outgoing postcard and the reply postcard are finished in a form folded from the cutoff line, so that the postcard can be posted as a round-trip postcard. Therefore, it is very convenient that the postcard has already been folded as in the present invention.
