Description

The present invention relates to a foldable communication device in which a plurality of leaflets are folded and releasably integrated, and more particularly to a foldable communication device that is extremely easy to peel and open, thereby making it easy to read the contents.

Conventionally, a common method for transmitting large amounts of information, such as advertising materials, invitations, pamphlets, etc., is to fold sheets printed with various communication materials into envelopes, enclose them in envelopes, and then mail them. However, in recent years, the management of personal information has become important, and accidents such as accidentally writing someone else's information or writing the wrong address and resulting in misdelivery must be avoided as much as possible. It is also desirable to reduce the significant costs involved in enclosing and sealing numerous advertising materials and sheets containing individual information. Under these circumstances, a folding envelope sheet has been proposed, as described in, for example, Japanese Patent Application Laid-Open No. 2000-43456.

The folding envelope sheet described in the cited references allows one person's personal information, including the recipient's address, to be written on a single sheet before folding it into an envelope, preventing the accidental inclusion of other people's information. It also has the advantage of eliminating the labor required for inserting and sealing the envelope, since the sheet automatically becomes an envelope when folded. However, it requires complex and time-consuming special processing, such as special processing of the protruding envelope, application of adhesive for sealing, perforation to tear off the envelope when opening, application of a release agent to allow the adhesive to be easily peeled off, and a double-perforated opening method, resulting in a relatively high cost despite the aforementioned advantages.

Furthermore, as mentioned above, the complicated structure of the envelope requires the recipient to go through complicated steps to open it, which can make older people in particular hesitate and cause them to accidentally damage the information surface by not being able to open it properly.

In view of the above problems, the foldable information communication body of the present invention is designed to be completed by writing information on a single sheet and folding it lengthwise and widthwise to complete the information communication body, thereby eliminating accidents such as the mistaken enclosing of someone else's information or the misdelivery of the information that often occurs when multiple sheets with various types of information written on them are enclosed in a single envelope; the principles for opening and peeling and unfolding are clear and simple, so even elderly people and the like will not be confused by the operation, and the information display surface will not be accidentally damaged or soiled when opening; and the information writing surface is protected by a pseudo-adhesive film sheet covering, so there is no need to worry about soiling, damage, tampering, etc.; and since no traces of breakage remain around the sheet after peeling and unfolding, the aesthetic appearance is not marred and no waste such as torn pieces is generated.

In order to achieve the above object, the foldable information communication body of the present invention is a foldable information communication body which is formed by folding a first unit sheet in which a plurality of leaves are connected horizontally via vertical fold lines, and an information communication body sheet in which a plurality of unit sheets having the same leaf configuration as the first unit sheet are arranged above and below via horizontal fold lines, and in which the entire front and back surfaces of the unit sheets are covered with a pseudo-adhesive film sheet, and then releasably bonding the opposing surfaces together, wherein the vertical width of the leaves of at least one set of unit sheets which make up the foldable information communication body sheet is different from the vertical width of the other unit sheets, and the horizontal width of at least one vertical row of leaves arranged above and below is different from the horizontal width of the other leaf rows, and after folding, the end faces of the vertical and horizontal edges do not match, forming a step, which can be used as a starting point for opening the body in the reverse direction of the fold to easily unfold it into its original flat state and check the information inside.

The manufacturing process of the foldable information communication medium of the present invention will be described as follows: a sheet unwinding step for unwinding a continuous sheet or individual sheets printed with a first unit sheet having a plurality of leaf pieces connected in the horizontal direction via vertical fold lines and a foldable information communication medium sheet having a plurality of unit sheets having the same leaf piece configuration as the first unit sheet and arranged above and below each other via horizontal fold lines; a pseudo-adhesive film sheet forming step for forming a pseudo-adhesive film sheet on the entire front and back surfaces of the unwinding folded information communication medium sheet ; The information communication sheet is manufactured by a manufacturing process comprising a first folding step of folding the formed foldable information communication sheet along a vertical fold line, a cutting step of cutting out the foldable information communication sheet folded along the vertical fold line into a single foldable information communication sheet, a second folding step of folding the cut-out foldable information communication sheet along a horizontal fold line, and a bonding step of releasably bonding opposing pseudo-adhesive film sheets of the foldable information communication sheet folded in the second folding step.

The size of each leaf in the present invention does not necessarily have to be the same, and by designing the vertical width of any unit sheet to be different from the vertical width of other unit sheets, or by designing the horizontal width of any vertical row of leaf pieces in a group of unit sheets connected vertically to be different from the horizontal width of other row of leaf pieces, a step is intentionally created on the vertical and horizontal edges of the folded information communication body after folding the information communication body sheet, which serves as a starting point for opening.

Suitable materials for use in the foldable communication medium of the present invention include ordinary paper such as fine paper, matte paper, coated paper, synthetic paper, nonwoven fabric, resin film sheet, etc. There are also no particular limitations on the finished size of the foldable communication medium, and it can be applied to various types of B5- or A4-sized communication mediums, such as postcards, rectangular envelopes, Yu-Mail, and mail-order items.

When manufacturing the foldable information communication body of the present invention, there is no particular limitation on the arrangement of the first and second folding steps and the cutting step for cutting out individual information communication body sheets, and the first and second folding steps may be arranged after the cutting step, or the cutting step and folding step may be arranged separately, and cutting and folding may be performed in stages.

In the cutting process, the vertical margins of the continuous sheet or individual sheets on which the folding information communication sheet is printed are cut off. In the case of a continuous sheet, this refers to the marginal portion where marginal holes for sheet transport are formed, while in the case of individual sheets, this refers to the marginal portion cut off by trimming. There are no particular restrictions on the timing of the cutting; the cutting may be done in advance before processing begins, or it may be done upstream or downstream of the pseudo-adhesive film sheet forming process. Furthermore, the cutting may be done in stages, upstream and downstream.

In manufacturing the foldable information communication medium of the present invention, a single foldable information communication medium sheet is cut out by cutting in the horizontal direction as well as the vertical direction. In the case of a continuous sheet, a cutting device such as a die-cut roller may be used to cut out a single sheet with a blade attached to a rotating cylinder, or in the case of a sheet, a cutting device such as a guillotine type cutting device consisting of a combination of a cutting blade and a fixed blade may be used to cut out the sheet while cutting along the length.
There are no particular restrictions on the timing or cutting method.

When manufacturing the foldable information communication object of the present invention, a folding means such as a folding perforation or a crease is formed on the longitudinal fold line of the information communication object sheet. The folding means may be formed in advance on the information communication object sheet, or may be formed upstream or downstream of the pseudo-adhesive film sheet forming process. Furthermore, the folding means may be formed in stages upstream and downstream. Regarding the horizontal fold line, the folding means described above may be formed, but the sheet may also be forcibly folded directly using a folding machine without forming any folding means. As mentioned above, there are no particular restrictions on the timing of folding.

The pseudo-adhesive film sheet used for peelably adhering the opposing folded surfaces (also called pseudo-adhesion) is called the film method, in which a pseudo-adhesive film sheet is coated (laminated) on the pseudo-adhesive surface of the printed paper, and the paper is folded so that the pseudo-adhesive film sheets face each other, and then heated or heated and pressurized to peelably adhere. There are two types of film methods: a full-surface adhesive method in which the opposing pseudo-adhesive surfaces are coated in advance and peelably adhered after folding, and a sandwich method in which a laminated film that has been pseudo-adhesive in advance is sandwiched between the pseudo-adhesive surfaces of the folded paper, and the paper and film are bonded together to peelably integrate them.

In the folding information communication body of the present invention, a single sheet on which all information is written is folded into an envelope during manufacturing, so that serious accidents such as information leakage (mixing of other people's information, etc.) that occur when a plurality of separate sheets on which personal information, etc., are written are enclosed and sealed respectively do not occur.

Simply put, the foldable information communication device of the present invention is a device that simply forms a pseudo-adhesive film sheet on the pseudo-adhesive surface and then folds and adheres it. Therefore, the opening procedure is as simple as simply unfolding it in the reverse direction. Since there are no complicated or intricate opening procedures, even elderly recipients can peel and open it very easily, and there is no risk of accidentally tearing the information display surface, making the internal information illegible, or damaging the appearance by soiling it.

Furthermore, since not only the pseudo-adhesive surface (concealed surface) on which personal information is written but all leaf surfaces are covered with a strong pseudo-adhesive film sheet, there is no risk of soiling, damage, or tampering.

Furthermore, after peeling and unfolding, no traces of the broken seal pieces remain around the periphery of the information communication sheet when it is opened, so the appearance is not marred and no waste is generated due to broken pieces after opening.

Furthermore, the foldable information communication device of the present invention can be manufactured automatically through the tedious process of forming various adhesive media and folding means, and can also be manufactured very easily using dedicated machines for each process.

Furthermore, since the pseudo-adhesive film sheet is formed on the entire front and back surfaces of the information communication sheet, unlike when it is formed only on an arbitrary part like a dropper, precise work that does not allow for misalignment is not required, and even an amateur can produce a large number of folded envelopes in a short time.

[Folding information communication unit J1]
2A and 2B, and its configuration is as shown in the cross-sectional view of FIG. 2A, in which the second leaf 2, first leaf 1, third leaf 3, and fourth leaf 4 are stacked in this order from top to bottom. The front and back surfaces of each leaf, which are connected via vertical fold lines 5 (where perforations are formed), are covered with pseudo-adhesive film sheets G, and the second leaf 2 and first leaf 1 (unit sheet t1), the third leaf 3 and fourth leaf 4 (unit sheet t2), and the first leaf 1 and third leaf 3 are releasably bonded and integrated by the pseudo-adhesive film sheets G interposed between the opposing surfaces of the second leaf 2 and first leaf 1 (unit sheet t1) , the third leaf 3 and fourth leaf 4 (unit sheet t2), and the first leaf 1 and third leaf 3.

The recipient of the foldable communication object J1 having the above-described configuration peels off the first leaf 1 and the third leaf 3, which are releasably integrated, by using, for example, the step formed along the upper edge as shown in Figures 1(A) and 2(B). By this peeling operation, the foldable communication object J1 is unfolded into a state folded in half, as shown in Figures 5(A), (B), and (C), so that the second leaf 2 and the fourth leaf 4 face the first leaf 1 and the third leaf 3, respectively, at the fold line 5.

5(A), (B), and (C), the recipient can use the steps formed along the right edge of each leaf to peel off the first leaf 1, the second leaf 2, the third leaf 3, and the fourth leaf 4, and unfold the envelope into its original flat state as shown in FIGS. 4(A) and (B). By doing so, the recipient can see the various information printed inside through the transparent or translucent pseudo-adhesive film sheet G. The shaded areas in FIGS. 4(A) and (B) indicate the areas covered by the pseudo-adhesive film sheet G.

[Manufacturing process of foldable information communication device J1]
3A and 3B, the information communication sheet S1 used in the manufacturing process of the folded information communication unit J1 of this embodiment comprises a unit sheet t1 in which two leaves having a width relationship of first leaf piece 1 > second leaf piece 2 are joined together horizontally via a vertical fold line 5, and two unit sheets having a width relationship of third leaf piece 3 (= first leaf piece 1) > fourth leaf piece 4 (= second leaf piece 2) joined together horizontally via a fold line 5, but with a vertical width relationship of unit sheet t1 < unit sheet t2, which are arranged one above the other so that first leaf piece 1 and third leaf piece 3, and second leaf piece 2 and fourth leaf piece 4, are joined together via a horizontal fold line 6. With this configuration, the areas of the four leaf pieces are all different.

The information communication sheet S1 may be printed on a continuous sheet used in form printing, or on a sheet used in offset printing or digital printing. This also applies to the manufacturing process of the embodiments described below.

In the manufacturing process of this embodiment, perforations are formed along the vertical fold line 5 to facilitate folding, but other known folding means such as creases may be used instead. The perforations may also be formed in a process upstream and/or downstream of the coating process of the pseudo-adhesive film sheet G, which will be described later. Furthermore, the pseudo-adhesive medium may be formed in advance on a continuous sheet or individual sheets at a stage prior to processing.

The horizontal fold lines 6 indicated by the two-dot chain lines, which will be forcibly folded later by a folding machine, may be left unattended, or may be provided with the above-mentioned known folding means.
The various processes applied to the information communication sheet S1 are also the same for the information communication sheets used in the manufacturing process of the following examples.

The information communication sheet S1 having the above-described configuration is placed on a paper loading table at the most upstream stage of the manufacturing process, and is fed, starting from the topmost information communication sheet S1, into a known coating device such as a laminator consisting of one or more pairs of heat rollers, and the entire front and back surfaces are coated with a pseudo-adhesive film sheet G as shown by the diagonal lines in Figures 4(A) and (B).

The pseudo-adhesive film sheet G covers the entire front and back surfaces of the information communication sheet S1. Therefore, the pseudo-adhesive film sheet G is applied using a double-sided laminator or the like so that it protrudes slightly beyond the information communication sheet, and then the surrounding margins are trimmed off, so the work does not require extreme precision compared to spot coating.

To assist the recipient in opening the package, a non-adhesive area can be provided by covering the edge of the package with a pseudo-adhesive film sheet G. In the manufacturing process of this embodiment, a step is created at the opening edge after folding, and this step serves as the starting point for peeling. Of course, both the non-adhesive area and the step may be used. This also applies to the manufacturing process of the embodiments described below.

The information communication sheet S1 coated with the pseudo-adhesive film sheet G as described above is folded in half from the vertical fold line 5 so that the back sides of the second leaf piece 2 and the first leaf piece 1 and the back sides of the fourth leaf piece 4 and the third leaf piece 3 face each other, as shown in Figures 5(A), (B) and (C), after, for example, cutting off unnecessary marginal portions around the periphery (there is no particular restriction as to when to cut off the marginal portions, and for example, any marginal portions may be cut off in stages).

Next, the sheet is folded in half as shown in Fig. 2(A) from the horizontal fold line 6 in Fig. 5(A) so that the pseudo-adhesive film sheets G covering the first leaf 1 and the third leaf 3 face each other. It is preferable that the information communication sheet S1 is cut into individual sheets at the time of folding in half, but it may be cut after the bonding process described below. This also applies to the manufacturing process of the examples described below.

Next, the opposing pseudo-adhesive film sheets G are bonded together in a bonding process using a pressure device such as a pressure roller, or a heating and pressure device such as a combination of a heat roller or a heater panel and a pressure roller, so that the entire folded information communication sheet S1 is peelably bonded and integrated. In this way, the folded information communication unit J1 is manufactured.

The above-mentioned processing steps may be performed automatically online from the stacking of the sheets to the final gluing step using a dedicated line, but each processing step (coating step, cutting step, folding step, gluing step, etc.) may also be performed offline using a separate dedicated processing device. This also applies to the manufacturing process of the embodiments described below.

[Folding information communication body J2]
6(A), (B) and 7(A), (B), and its configuration is as shown in the cross-sectional view of Fig. 7(A), in which a first leaf 11, a second leaf 12, a third leaf 13, a sixth leaf 16, a fifth leaf 15, and a fourth leaf 14 are stacked in this order from top to bottom. The front and back surfaces of each leaf, which are connected via vertical fold lines 17 and 18 (where perforations are formed), are covered with pseudo-adhesive film sheets G, and the leaves are releasably bonded together by the pseudo-adhesive film sheets G interposed between the opposing surfaces to form a single unit.

The recipient of the foldable communication object J2 having the above-described configuration uses the steps formed along the upper edge, for example, as shown in Figures 6(A) and 7(B), to peel off the third leaf piece 13 and the sixth leaf piece 16, which are releasably integrated together. By this peeling operation, the foldable communication object J2 unfolds into a state in which the first leaf piece 11, the second leaf piece 12, the third leaf piece 13, the fourth leaf piece 14, the fifth leaf piece 15, and the sixth leaf piece 16 are folded into a Z-shaped cross section, as shown in Figures 10(A), (B), and (C).

10(A), (B), and (C), the recipient uses the steps formed along the left edge of each leaf to peel off the first leaf 11, the second leaf 12, the fourth leaf 14, and the fifth leaf 15, and then peel off the second leaf 12, the third leaf 13, the fifth leaf 15, and the sixth leaf 16, finally unfolding the envelope into its original flat state as shown in FIGS. 9(A) and (B). By doing so, the recipient can see the various information printed inside through the transparent or translucent pseudo-adhesive film sheet G. The shaded areas in FIGS. 9(A) and (B) indicate the areas covered by the pseudo-adhesive film sheet G.

[Manufacturing process of foldable information communication unit J2]
As shown in Figures 8 (A) and (B), the information communication body sheet S2 used in the manufacturing process of the folded information communication body J2 of this embodiment consists of a unit sheet t11 in which three leaflets with a width relationship of first leaflet 11 < second leaflet 12 = third leaflet 13 are connected horizontally via vertical fold lines 17 and 18, and two unit sheets in which three leaflets with a width relationship of fourth leaflet 14 (= first leaflet 11) < fifth leaflet 15 (= second leaflet 12) = sixth leaflet 16 (= third leaflet 13) are connected horizontally via fold lines 17 and 18, and the vertical width relationship is unit sheet t11 < unit sheet t12, which are arranged one above the other so that the first leaflet 11 and the fourth leaflet 14, the second leaflet 12 and the fifth leaflet 15, and the third leaflet 13 and the sixth leaflet 16 are in contact via horizontal fold line 19.

The information communication sheet S2 having the above-described configuration is placed on a paper loading table at the most upstream stage of the manufacturing process, and is fed sequentially, starting with the topmost information communication sheet S2, into a known coating device such as a laminator consisting of one or more pairs of heat rollers, and the entire front and back surfaces are coated with a pseudo-adhesive film sheet G as shown by the diagonal lines in Figures 9(A) and (B).

As described above, the information communication sheet S2 coated with the pseudo-adhesive film sheet G is, for example, after unnecessary marginal portions around the periphery are cut off (there is no particular restriction as to when to cut off the marginal portions, and for example, any marginal portions may be cut off in stages), and the first leaf piece 11, the second leaf piece 12, the third leaf piece 13, the fourth leaf piece 14, the fifth leaf piece 15, and the sixth leaf piece 16 are folded into a Z-shaped cross section from the vertical fold lines 17 and 18, as shown in Figures 10 (A), (B), and (C).

Next, the sheet is folded in half as shown in Fig. 7A, so that the third leaf piece 13 and the sixth leaf piece 16 face each other along the horizontal fold line 19 in Fig. 10A. It is preferable that the information communication sheet S2 is cut into a single sheet at the time of folding in half, but it may be cut out after the bonding step described below.

Next, the opposing pseudo-adhesive film sheets G are bonded together in a bonding process using a pressure device such as a pressure roller, or a heating and pressure device such as a combination of a heat roller or a heater panel and a pressure roller, so that the entire folded information communication sheet S2 is peelably bonded and integrated. In this way, the folded information communication object J2 is manufactured.

[Folding information communication unit J3]
12(A), (B), and 12(A), (B), and its configuration is as shown in the cross-sectional view of Fig. 12(A), in which the first leaf 21, the second leaf 22, the third leaf 23, the sixth leaf 26, the fifth leaf 25, the fourth leaf 24, the seventh leaf 27, the eighth leaf 28, and the ninth leaf 29 are stacked in this order from top to bottom. The front and back surfaces of the leaves connected via vertical fold lines 30 and 31 (where perforations are formed) are covered with pseudo-adhesive film sheets G, and the leaves are releasably bonded together by the pseudo-adhesive film sheets G interposed between the opposing surfaces to form a single unit.

The recipient of the foldable information communication object J3 having the above-described configuration uses the steps formed along the upper edge as shown in Figures 11(A) and 12(B) to peel off the third leaf piece 23 and the sixth leaf piece 26, which are releasably integrated. Then, the fourth leaf piece 24 and the seventh leaf piece 27 are peeled off, and the unit sheets t21, t22, and t23 are folded into a Z-shaped cross section and unfolded into a state connected vertically along horizontal fold lines 32 and 33, as shown in Figures 15(A), (B), and (C).

15(A), (B), (C), and (D) , the recipient utilizes the steps formed along the left edge of each leaf to peel off the first leaf 21 from the second leaf 22, the fourth leaf 24 from the fifth leaf 25, and the seventh leaf 27 from the eighth leaf 28, and then peel off the second leaf 22 from the third leaf 23, the fifth leaf 25 from the sixth leaf 26, and the eighth leaf 28 from the ninth leaf 29, ultimately unfolding the envelope into its original flat state as shown in FIGS. 14(A) and (B). By doing so, the recipient can view the various information printed inside through the transparent or translucent pseudo-adhesive film sheet G. The shaded areas in FIGS. 14(A) and (B) indicate the areas covered by the pseudo-adhesive film sheet G.

[Manufacturing process of the folding information communication unit J3]
As shown in Figures 13(A) and (B) , the information communication unit sheet S3 used in the manufacturing process of the folded information communication unit J3 of this embodiment is a unit sheet t21 in which three leaf pieces, the width of which is first leaf piece 21 < second leaf piece 22 = third leaf piece 23, are connected in the horizontal direction via vertical fold lines 30 and 31, and a unit sheet t22 in which the width of which is similarly the fourth leaf piece 24 (= first leaf piece 21) < fifth leaf piece 25 (= second leaf piece 22) = sixth leaf piece 26 (= third leaf piece 23), and a unit sheet t22 in which the width of which is similarly the seventh leaf piece 27 (= first leaf piece 21 = fourth leaf piece 24) < eighth leaf piece 28 (= second leaf piece 29). The three leaflets of each unit sheet t23 of unit sheets t21 (= fifth leaflet 25) = ninth leaflet 29 (= third leaflet 23 = sixth leaflet 26) are connected horizontally via fold lines 30 and 31, and three unit sheets whose vertical width relationship is unit sheet t21 < unit sheet t22 = unit sheet t23 are arranged vertically via fold lines 32 and 33 so that the first leaflet 21, the fourth leaflet 24, and the seventh leaflet 27, the second leaflet 22, the fifth leaflet 25, and the eighth leaflet 28, and the third leaflet 23, the sixth leaflet 26, and the ninth leaflet 29 are in contact.

The information communication sheet S3 having the above-described configuration is placed on a paper loading table at the most upstream stage of the manufacturing process, and is fed, starting from the topmost information communication sheet S3, into a known coating device such as a laminator consisting of one or more pairs of heat rollers, and the entire front and back surfaces are coated with a pseudo-adhesive film sheet G as shown by the diagonal lines in Figures 14 (A) and (B).

The information communication sheet S3 coated with the pseudo-adhesive film sheet G as described above is folded, for example, after cutting away unnecessary marginal portions around it (there is no particular restriction as to when to cut away the marginal portions, and any marginal portions may be cut away in stages), so that the leaf pieces constituting each unit sheet overlap in a Z-shaped cross section from the vertical fold lines 30 and 31, as shown in Figures 15(A), (B) and (C).

Next, as shown by the arrows in Fig. 16 from the horizontal fold lines 32 and 33 in Fig. 15(A), the sheet is folded into the state shown in Fig. 12(A) so that the third leaf piece 23 faces the sixth leaf piece 26, and the fourth leaf piece 24 faces the seventh leaf piece 27. It is preferable that the information communication sheet S3 is cut into individual sheets at the time of folding into this state, but it may be cut out after the bonding step described below.

Next, the opposing pseudo-adhesive film sheets G are bonded together in a bonding process using a pressure device such as a pressure roller, or a heating and pressure device such as a combination of a heat roller or a heater panel and a pressure roller, so that the entire folded information communication sheet S3 is peelably bonded and integrated. In this way, the folded information communication unit J3 is manufactured.

The present invention is not limited to the above-described embodiment.
For example, there is no limit to the number of leaves. Simply fold an information communication sheet, which is made up of multiple unit sheets, each with multiple leaves connected horizontally, connected vertically, so that there are steps along the vertical and horizontal edges after folding. Once the sheet is opened, with the initial step serving as the starting point for peeling, even if leaves of the same length and width are bonded together, steps will inevitably occur when the sheet is subsequently unfolded because other leaves are connected.
There is also no limitation on the manner of folding, and accordion folding, roll folding, gate folding, or a combination of these folding methods can be adopted.
