Description

Technical Field

[0001] The present invention relates to a folded information communication body used for direct mail and sealed letters. Specifically, it relates to a folded information communication body obtained by folding a sheet of paper connecting a plurality of leaves and adhesively bonding and sealing an edge that becomes an opening at one place in a peelable manner.

Background Art

[0002] In recent years, as the network environment has been improved and spread, the demand for printed materials on paper media has been decreasing. This also affects direct mail and the like, which have contributed to the expansion of sales channels for products, services, etc. In addition, due to the increase in postal rates and other factors, the total number has decreased rapidly.

[0003] Therefore, as a printing company mainly dealing with direct mail, items that provide many merits to the user side are required to face the above-mentioned network environment. For example, a sealed letter for direct mail of Utility Model Registration No. 3030660 has been devised.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the device of the cited reference, a paste margin coated with a peelable pressure-sensitive adhesive is provided only at the outer edge of the cover, and it becomes a sealed letter just by crimping this paste margin part. Therefore, although there is an advantage that it does not take time to seal and open, and the manufacturing cost can be kept low, there are many disadvantages as follows.

[0006] The aforementioned disadvantages include the need to create the outer paper A, which consists of the front cover 1, back cover 2, and folded edge 3, and the advertising paper 7 (one or more sheets) in separate processes, and the need for complex processes such as aligning the outer paper A and the advertising paper 7 along the folding line 5, and then gluing or stapling them together.

[0007] Furthermore, because it is composed of multiple separate forms, there is a possibility that someone else's personal information may be accidentally included, making it impossible to avoid the problem of information leakage.

[0008] Furthermore, an extremely difficult folding process is also required, which involves folding the advertising paper 7 in half, then folding the folded edge 3 back onto the advertising paper 7, and finally folding the back cover 2 onto the folded edge 3.

[0009] Furthermore, the peelable pressure-sensitive adhesive applied to the folded edge 3 can cause accidents such as adhesion to unintended areas, thus reducing the yield in the work process.

[0010] In view of the above problems, the present invention provides a foldable information communication device in which a single sheet of paper, with multiple connected leaf-shaped pieces, is folded in a known simple folding manner and the edges that serve as the opening are crimped, without the use of complex processing steps or materials that reduce yield, thereby greatly contributing to cost reduction, preventing accidents where other people's information may be mixed in, and further promoting increased purchasing intent by making a strong impression on the recipient of the contents written in the envelope. [Means for solving the problem]

[0011] To achieve the above objective, the foldable information communication body of the present invention is a foldable information communication body made by folding a foldable information communication body paper consisting of a total of four leaves, two leaves each connected vertically and horizontally via vertical and horizontal fold lines, initially from the vertical fold line, and then folding and overlapping from the horizontal direction. The vertical open edges of opposing leaves are detachably bonded with a pseudo-adhesive medium, and after peeling and opening, it unfolds back to its original flat state.

[0012] Furthermore, in order to achieve the above objective, a different embodiment of the foldable information communication body of the present invention is a foldable information communication body made by folding a foldable information communication body paper consisting of a total of four leaves, two leaves each connected vertically and horizontally via vertical and horizontal fold lines, initially from the vertical fold line and then folded horizontally and overlapped, characterized in that the vertical open edges of opposing leaves are peelably bonded with a pseudo-adhesive medium, the open edge on the vertical fold line side of the central opposing leaf is non-peelably bonded, and the lower edge is cut off when opening to unfold it into a bound state.

[0013] Furthermore, in order to achieve the above objective, a different embodiment of the foldable information communication body of the present invention is characterized in that, when the foldable information communication body is unfolded into the bound state, the lower edge is pre-cut.

[0014] The paper used in this invention can be any known sheet, such as high-quality paper, matte paper, coated paper, synthetic paper, nonwoven fabric, or resin film sheet. The paper used for the folded information and communication body may be printed on long sheets used for business form printing or web printing, or on sheet-fed sheets used for offset printing.

[0015] As a pseudo-adhesive medium for peelably bonding the opening edge, it is selected from a medium that has the property of peelably bonding only the portions where the forming surfaces of the pseudo-adhesive medium face each other, upon addition of necessary conditions. For example, pseudo-adhesive UV varnish or pseudo-adhesive laminate film can be suitably used as such.

[0016] The aforementioned pseudo-adhesive medium, after being formed on the pseudo-adhesion surface of the leaf fragments, adheres only to the parts that face each other when folded as described above, upon the addition of necessary conditions. Therefore, it exhibits no adhesive properties at all in the work processes prior to the compression process, making it extremely convenient and contributing to improved work efficiency.

[0017] As a fully adhesive medium for irremovably bonding the opening edges, it is selected from media that exhibit irremovable adhesion only in the portions where the forming surfaces of the fully adhesive medium face each other, upon the addition of necessary conditions. Suitable examples of such media include those that exhibit adhesion when specific conditions such as heat sensitivity, pressure sensitivity, and moisture sensitivity are applied, or fully adhesive film sheets formed on film sheets such as OPP or PET.

[0018] The vertical and horizontal widths of the four leaf-shaped segments that constitute the foldable information communication body of the present invention can be arbitrarily determined. Since the overall outline is rectangular, the vertical widths of the two horizontally connected leaf-shaped segments are automatically the same, and the horizontal widths of the two vertically connected leaf-shaped segments are the same. By changing the vertical and horizontal widths of each leaf-shaped segment, the edges do not coincide after folding, creating a step, but this step can be suitably used as a starting point for opening.

[0019] Furthermore, the length and width of the four leaflets may be the same. In that case, by forming the pseudo-adhesive medium inward from the opening edge, a non-adhesive area is created along the edge where the pseudo-adhesive mediums do not face each other when folded, and this non-adhesive area may be used as the starting point for opening. [Effects of the Invention]

[0020] The foldable information communication device of the present invention does not require complex processes during manufacturing because it is constructed by folding a single sheet of paper consisting of four leaves arranged in a grid pattern using a known, simple folding method. Furthermore, since the pseudo-adhesive medium and the fully adhesive medium do not exhibit adhesive properties in the manufacturing process prior to the crimping process, handling is easy and yield is improved. Consequently, a significant reduction in manufacturing costs can be achieved. Furthermore, because it is composed of a single folded information communication sheet, personal information such as printing is reliably entered, ensuring that the recipient's information is accurately recorded. This prevents information leakage incidents such as the inclusion of other people's information, which can occur with envelopes made of multiple pieces of paper. Furthermore, it also conforms to forms such as Yu-mail, etc., is advantageous in terms of cost, and also exhibits effects such as improving the purchasing desire because it is a form that attracts the interest of the recipient.

[0022] The present invention will be explained below in an easy-to-understand manner with reference to the drawings. In the following embodiments, a pseudo-adhesive film sheet G is used as the pseudo-adhesive medium. The pseudo-adhesive film sheet G can be made by applying a pseudo-adhesive treatment to one side of a known film sheet such as OPP or PET, and interposing various known adhesives on the other side to cover the surface of the printed material to be pseudo-adhered. When the covered printed material is folded and the pseudo-adhesive film sheets G are placed facing each other and pressure or heat-pressure treatment is applied, they become peelably bonded.

[0023] Similarly, a fully adhesive film sheet K is used as the fully adhesive medium. The fully adhesive film sheet K can be made by applying a fully adhesive treatment to one side of a film sheet such as a known OPP or PET, and interposing various known adhesives on the other side to cover the surface of the printed material to be fully adhered. When the covered printed material is folded and the fully adhesive film sheets K are placed facing each other and pressure or heat-pressure treatment is applied, they adhere irremovably.

[0024] [Foldable Information and Communication Device J1] The foldable information communication body J1 of the present invention has front and back surfaces as shown in Figures 1(A) and (B). As shown in the cross-sectional view of Figure 2(A), the foldable information communication unit J1 is folded and stacked from top to bottom in the order of the first leaf 1, second leaf 2, fourth leaf 4, and third leaf 3 along fold lines 5 and 6. The relationship between the length and width of each leaf segment in this figure will be described later. As shown in Figure 2(A), the vertical open edges of each opposing surface are sealed in a peelable manner by the adhesion of the opposing surfaces of the pseudo-adhesive film sheet G.

[0025] The recipient of the foldable information communication device J1 of the present invention can open it step by step, using the steps at each edge shown in Figures (A) and (B) as the starting point for peeling, and finally unfold it into a flat shape as shown in Figure 3, allowing them to view the information inside. Since the pseudo-adhesive film sheet G is semi-transparent or transparent, there is no problem with visibility even if it covers the surface of the information written inside.

[0026] To further clarify the configuration of the foldable information communication device J1 of the present invention, the manufacturing sequence is described below. Figures 4(A) and (B) show the foldable information communication sheet S1 used in the manufacture of the foldable information communication sheet J1. As is clear from the drawings, four sheets are arranged in a grid pattern via vertical and horizontal fold lines 5 and 6. Note that each of the fold lines may have known folding means such as fold lines or creases formed on them. The relationship of the widths of the sheets is first sheet 1 = third sheet 3 < second sheet 2 = fourth sheet 4. The relationship of the vertical widths is first sheet 1 = second sheet 2 > third sheet 3 = fourth sheet 4, and the sheet is designed so that a step is formed at any edge when folded.

[0027] As shown in Figure (A), the pseudo-adhesive film sheet G is applied to the longitudinal edges of each leaf surface along (spanning) the longitudinal fold line 5, and the pseudo-adhesive film sheet G is applied parallel to the first pseudo-adhesive film sheet G along the longitudinal outer edges of the second leaf 2 and the fourth leaf 4.

[0028] Furthermore, as shown in Figure (B), the pseudo-adhesive film sheet G is applied parallel to the outer vertical edges of the second leaf 2 and the fourth leaf 4, and to the outer vertical edges of the first leaf 1 and the third leaf 3. The foldable information and communication paper S1 may be printed on a long sheet used for business form printing, or on a single-fed sheet used for offset printing, and the figure shows the paper after it has been cut out individually from each sheet after going through the coating process of the pseudo-adhesive film sheet G.

[0029] The foldable information communication paper S1 with the above configuration is folded in half along the central vertical fold line 5 so that the back surfaces of the first leaf 1 and the second leaf 2, and the third leaf 3 and the fourth leaf 4 face each other, as indicated by the arrows in Figures 5(A) and (B), and is folded to the state shown in Figures 6 and 7(A) and (B).

[0030] Then, the second leaf 2 shown in Figure 7(A) and the fourth leaf 4 shown in Figure 7(B) are folded in half along the horizontal fold line 6 shown in Figure 6 so that they face each other, resulting in the state shown in Figures 1(A) and (B) and Figures 2(A) and (B). In this state, the pseudo-adhesive film sheets G facing each other at the open edge are not yet adhered. Subsequently, by going through the pressing or heating and pressing process, which is the bonding condition for the pseudo-adhesive film sheets, the pseudo-adhesive film sheets G facing each other at the open edge are bonded and sealed so that they can be peeled off.

[0031] [Foldable Information and Communication Device J2] The foldable information communication body J2 of the present invention has front and back surfaces as shown in Figures 8(A) and (B). As shown in the cross-sectional view of Figure 9(A), the foldable information communication unit J2 is folded and stacked from top to bottom in the order of the first leaf 11, second leaf 12, fourth leaf 14, and third leaf 13 along the fold lines 15 and 16. The relationship between the length and width of each leaf segment in this figure will be described later. As shown in Figure 9(A), the open edge on the left vertical direction is sealed in a peelable manner by adhesion between opposing surfaces of the pseudo-adhesive film sheet G, while the open edge on the right vertical direction is permanently bonded by the fully adhesive film sheet K.

[0032] The recipient of the foldable information communication body J2 of the present invention shall follow the cutting perforations 17 (which may be indicated by known means such as dashed lines or perforations) or indications suggesting cutting, such as "cutting line" or "cut off from here," which are indicated along the lower edge of the foldable information communication body J2 as shown in Figure 8. Following the instructions in TIFF2026057421000002.tif8170, the document can be opened step by step, using the steps along each edge as a starting point for peeling. Ultimately, as shown in Figure 10, it can be unfolded into an 8-page spread bound state, allowing the internal information to be viewed. Since the pseudo-adhesive film sheet G is semi-transparent or transparent, there is no problem with visibility even if it covers the surface of the information written inside.

[0033] Furthermore, there is no need to guide the recipient to perform the cutting action with the aforementioned indication; the cutting can be done in advance during manufacturing. Doing so eliminates the need to search for cutting tools and prevents information from being corrupted due to incorrect cutting. It also eliminates the generation of waste such as scraps from cutting, making it very convenient.

[0034] To further clarify the configuration of the foldable information communication device J2 of the present invention, the manufacturing sequence is described below. Figures 11(A) and (B) show the foldable information communication sheet S2 used in the manufacture of the foldable information communication sheet J2. As is clear from the drawings, four sheets are arranged in a grid pattern via fold lines 15 and 16. Note that each of the fold lines may have known folding means such as fold lines or creases formed on them. The relationship of the widths of each sheet is first sheet 11 = third sheet 13 < second sheet 12 = fourth sheet 14. The relationship of the heights is first sheet 11 = second sheet 12 > third sheet 13 = fourth sheet 14, and the sheet is designed so that a step is formed at any edge when folded.

[0035] As shown in Figure (A), the fully adhesive film sheet K is applied to the longitudinal edges of each leaf surface along (spanning) the longitudinal fold line 15, and the pseudo-adhesive film sheet G is applied parallel to the fully adhesive film sheet K along the longitudinal outer edges of the second leaf 12 and the fourth leaf 14.

[0036] Furthermore, as shown in Figure (B), the pseudo-adhesive film sheet G is applied parallel to the vertical outer edges of the second leaf 12 and the fourth leaf 14, and to the vertical outer edges of the first leaf 11 and the third leaf 13. The foldable information and communication paper S2 may be printed on a long sheet used for business form printing, or on a single-fed sheet used for offset printing, and the figure shows each sheet after it has been cut into individual pieces after going through the coating process of the fully adhesive sheet K and the pseudo-adhesive film sheet G.

[0037] The foldable information communication paper S2 with the above configuration is folded in half from the central vertical fold line 15 so that the back surfaces of the first leaf 11 and the second leaf 12, and the third leaf 13 and the fourth leaf 14 face each other, as indicated by the arrows in Figures 12(A) and (B), and is folded to the state shown in Figures 13 and 14(A) and (B).

[0038] Then, the film is folded in half along the horizontal fold line 16 shown in Figure 13, so that the second leaf 12 shown in Figure 14(A) and the fourth leaf 14 shown in Figure 14(B) face each other, resulting in the state shown in Figures 8(A) and (B) and Figures 9(A) and (B). In this state, the pseudo-adhesive film sheets G and fully adhesive film sheets K facing each other at the open edge are not yet adhered. Subsequently, by going through the pressing or heating and pressing process, which is the bonding condition for each adhesive film sheet, the adhesive film sheets facing each other at the open edge are bonded together in a way that makes them peelable or non-peelable, and then sealed.

[0039] However, the present invention is not limited to the embodiments described above. For example, in this embodiment, the width of each leaf of the foldable information communication paper S1 is given as follows: horizontal width relationship is first leaf = third leaf < second leaf = fourth leaf, and vertical width relationship is first leaf = second leaf > third leaf = fourth leaf. However, the width relationship is not limited to this. That is, the horizontal width relationship may be first leaf = third leaf ≥ second leaf = fourth leaf, or the vertical width relationship may be first leaf = second leaf ≤ third leaf = fourth leaf.

[0040] Furthermore, instead of using the step as the starting point for opening, for example as shown in Figure 15, the opening-side edges of the first and third leaf segments are aligned without forming a step, and the non-adhesive area H formed by covering the pseudo-adhesive film sheet G from the open edge is used as the starting point for opening, and the edges of each leaf segment can be pinched with the fingertips to open them.

[0041] Furthermore, while this embodiment uses a pseudo-adhesive film sheet that can be used in print lamination as a pseudo-adhesive medium, it goes without saying that other pseudo-adhesive UV varnishes and emulsion-type pseudo-adhesive adhesives (all of these pseudo-adhesive media only exhibit pseudo-adhesion when they face each other and meet the necessary conditions) can also be used.
