Description

[Technical Field]

[0001] The present disclosure relates to sheet-like printed matter. [Background technology]

[0002] Conventionally, there has been known a sheet-like printed matter having a plurality of sheets that are peelably stacked (see, for example, Patent Document 1). In conventional sheet-like printed matter, a portion of each sheet is partitioned by a cut line, and a flap section that can be peeled from the lower sheet is formed. The upper flap section covers the lower flap section. The upper and lower flap sections are printed differently. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-35783 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional sheet-like printed materials do not mention the relevance of printed content. In other words, conventional sheet-like printed materials are not designed to sequentially disclose related information related to a given piece of information even when a portion of the sheet is opened. Furthermore, in conventional sheet-like printed materials, the entire upper sheet is releasably adhered to the lower sheet, which may result in the entire upper sheet peeling off from the lower sheet, causing the upper and lower sheets to completely separate.

[0005] The present disclosure has been made with an eye on the above-mentioned problem, and aims to provide a sheet-like printed material that can sequentially disclose related information related to specified information by sequentially opening parts of the sheet. [Means for solving the problem]

[0006] In order to achieve the above object, the sheet-like printed matter of the present disclosure comprises a printable first sheet arranged at the bottom layer, at least one printable intermediate sheet having an intermediate door section that allows a portion of the sheet to be opened and closed and attached to the first sheet via a first adhesive layer having a non-adhesive area that faces the intermediate door section, and a printable second sheet having a surface door section that allows a portion of the sheet to be opened and closed and covers the intermediate door section and attached to the intermediate sheet via a second adhesive layer having a non-adhesive area that faces the surface door section, wherein predetermined first information is printed on the surface door section, second information related to the first information is printed on the intermediate door section, and third information related to at least one of the first information or the second information is printed in the area of ​​the first sheet covered by the intermediate door section. [Effects of the Invention]

[0007] As a result, the sheet-like printed material of the present disclosure can sequentially reveal related information about predetermined information by sequentially opening portions of the sheet. [Brief explanation of the drawings]

[0009] The embodiments for carrying out the sheet-shaped printed matter of the present disclosure will be described below with reference to the drawings.

[0010] The sheet-like printed material 1 of this embodiment is produced by stacking papers that are partially or entirely printed. As shown in Fig. 2, the sheet-like printed material 1 includes a first sheet 10, an intermediate sheet 20, and a second sheet 30.

[0011] The first sheet 10 is a paper that can be printed on both sides. The first sheet 10 is made of any paper, such as high-quality paper or coated paper. The first sheet 10 is disposed at the bottom of the sheet-like printed matter 1.

[0012] The intermediate sheet 20 is paper that can be printed on both sides. The intermediate sheet 20 is formed from any paper, such as high-quality paper or coated paper. The intermediate sheet 20 may be the same type of paper as the first sheet 10, or may be a different type of paper. In this embodiment, the intermediate sheet 20 is made from a single sheet of paper. The intermediate sheet 20 is arranged in the middle layer of the sheet-like printed matter 1.

[0013] Here, the intermediate sheet 20 is formed with an intermediate door portion 21 and an intermediate seal piece 22. In addition, a first adhesive layer 40 is provided on the back surface of the intermediate sheet 20 facing the first sheet 10. The intermediate sheet 20 is attached onto the first sheet 10 via the first adhesive layer 40.

[0014] The middle door section 21 is a mechanism that allows a part of the middle sheet 20 to be opened and closed. The middle door section 21 is divided by a middle dividing line 23 that is made up of a middle cut line 23a and a middle fold line 23b. The size, number, arrangement, etc. of the middle door section 21 can be freely set.

[0015] The intermediate cut line 23a is a continuous cut that tears the intermediate sheet 20. The intermediate fold line 23b has a structure that allows the intermediate sheet 20 to be folded in a predetermined direction without tearing the intermediate sheet 20. In this embodiment, the intermediate fold line 23b is formed by perforations. "Perforations" refers to a portion where multiple holes or multiple short slits that penetrate the intermediate sheet 20 are lined up in a certain direction at regular intervals. The intermediate cut line 23a and the intermediate fold line 23b are continuous.

[0016] Furthermore, an adhesive portion 24 is provided on the back surface 21b of the middle door section 21 facing the first sheet 10. The adhesive portion 24 removably adheres a portion of the middle door section 21 to the first sheet 10. Here, the adhesive portion 24 is made of adhesive glue applied to a portion of the middle door section 21. Adhesive glue is a type of glue that has both liquid and solid properties and can adhere to an attachment surface by applying slight pressure.

[0017] The intermediate seal piece 22 is a paper piece that can be removed from the intermediate sheet 20. The intermediate seal piece 22 is defined by a score line 25 that tears the intermediate sheet 20 all around.

[0018] The first adhesive layer 40 is made of an adhesive glue. Here, the first adhesive layer 40 attaches the intermediate sheet 20 to the first sheet 10 with an adhesive force that allows the intermediate sheet 20 to be peeled off from the first sheet 10. In this embodiment, the same type of adhesive is used for the adhesive glue that makes up the first adhesive layer 40 and the adhesive glue that makes up the adhesive portion 24.

[0019] The first adhesive layer 40 also has a non-adhesive region 41 that faces the middle door section 21. The non-adhesive region 41 is a region where the middle sheet 20 is not adhered to the first sheet 10. In other words, no adhesive glue is applied to the back surface 21b of the middle door section 21. The non-adhesive region 41 is set only on the back surface 21b side of the middle door section 21, and is not set on the back surface 22b side of the middle seal piece 22. Therefore, adhesive glue is applied to the back surface 22b of the middle seal piece 22. In other words, the middle seal piece 22 is removably adhered to the first sheet 10. This allows the middle sheet piece 22 to be removably attached to the first sheet piece 10.

[0020] The first adhesive layer 40 of this embodiment has a peripheral non-adhesive region 42 that surrounds the non-adhesive region 41. The peripheral non-adhesive region 42 is a region where the intermediate sheet 20 is not adhered to the first sheet 10, and is a predetermined range that surrounds the non-adhesive region 41. The size of the peripheral non-adhesive region 42 can be set as desired. For this reason, in this embodiment, the adhesive glue that constitutes the first adhesive layer 40 is applied to regions other than the non-adhesive region 41 and the peripheral non-adhesive region 42, i.e., the regions marked with dots in FIG. 3 .

[0021] The second sheet 30 is paper that can be printed on both sides. The second sheet 30 is formed from any paper, such as high-quality paper or coated paper. The second sheet 30 may be the same type of paper as the first sheet 10 or the intermediate sheet 20, or may be a different type of paper. The second sheet 30 is also disposed as the uppermost layer (surface layer) of the sheet-like printed matter 1.

[0022] Here, the second sheet 30 is formed with a front flap portion 31 and a front seal piece 32. In addition, a second adhesive layer 50 is provided on the back surface of the second sheet 30 facing the intermediate sheet 20. The second sheet 30 is attached to the intermediate sheet 20 via the second adhesive layer 50.

[0023] The front door section 31 is a mechanism that allows a portion of the second sheet 30 to be opened and closed. The front door section 31 is defined by a front dividing line 33 that is composed of a front cut line 33a and a front fold line 33b. The front door section 31 covers the middle door section 21 when the second sheet 30 is attached to the middle sheet 20. In this embodiment, the middle cut line 23a and the front cut line 33a overlap, and the middle fold line 23b and the front fold line 33b overlap. In other words, the middle dividing line 23 and the front dividing line 33 overlap. The middle door section 21 and the front door section 31 have the same shape.

[0024] The surface cut lines 33a are continuous cuts that break the second sheet 30. The surface fold lines 33b are structured to allow the second sheet 30 to be folded in a predetermined direction without breaking the second sheet 30. The surface fold lines 33b in this embodiment are formed by perforations, similar to the intermediate fold lines 23b. The surface fold lines 33b are continuous with the surface cut lines 33a.

[0025] The front seal piece 32 is a piece of paper that can be removed from the second sheet 30. The entire periphery of the front seal piece 32 is defined by a cut line 35 that tears through the second sheet 30. The front seal piece 32 also covers the intermediate seal piece 22 when the second sheet 30 is attached to the intermediate sheet 20. In this embodiment, the cut line 25 and the cut line 35 overlap, and the intermediate seal piece 22 and the front seal piece 32 have the same shape.

[0026] The second adhesive layer 50 is made of adhesive glue. Adhesive glue is a type of glue that is liquid before application and hardens to a solid. Adhesive glue generally has a stronger adhesive strength after hardening than tacky glue. In this embodiment, the second adhesive layer 50 attaches the second sheet 30 to the intermediate sheet 20 with an adhesive strength that prevents the second sheet 30 from peeling off from the intermediate sheet 20.

[0027] The second adhesive layer 50 also has a non-adhesive region 51 facing the front door piece 31. The non-adhesive region 51 is a region where the second sheet 30 is not adhered to the intermediate sheet 20. In other words, no adhesive glue is applied to the back surface 31b of the front door piece 31. The non-adhesive region 51 is set only on the back surface 31b side of the front door piece 31, and is not set on the back surface 32b side of the front seal piece 32. Therefore, adhesive glue is applied to the back surface 32b of the front seal piece 32. As a result, the front seal piece 32 is adhered to the intermediate seal piece 22 with an adhesive strength that prevents peeling.

[0028] The second adhesive layer 50 of this embodiment has a peripheral non-adhesive region 52 that surrounds the non-adhesive region 51. The peripheral non-adhesive region 52 is a region where the second sheet 30 is not adhered to the intermediate sheet 20, and is a predetermined range that surrounds the non-adhesive region 51. The size of the peripheral non-adhesive region 52 can be set as desired. For this reason, in this embodiment, the adhesive glue that constitutes the second adhesive layer 50 is applied to regions other than the non-adhesive region 51 and the peripheral non-adhesive region 52, i.e., the regions marked with dots in FIG. 4.

[0029] Predetermined first information A is printed on the front flap portion 31. Predetermined second information B is printed on the middle flap portion 21. Furthermore, predetermined third information C is printed in an area of ​​the first sheet 10 that is covered by the middle flap portion 21 when the middle sheet 20 is attached to the first sheet 10 (hereinafter referred to as "information area 11").

[0030] The first information A is any information displayed using letters, numbers, symbols, illustrations, photographs, two-dimensional barcodes, etc. In the example shown in FIG. 5A, the first information A is displayed on the front surface 31a of the front flap portion 31 using the following letters, etc.: "Kanji Question," "Q1. How do you read this kanji?", "Tuna," and "The answer is here ▽." In the example shown in FIG. 5B, the first information A is displayed on the back surface 31b of the front flap portion 31 using the following letters, etc. and an illustration of a fish: "A1. Tuna," "Did you get it right? Let's ask another question!" and "Continued here ▼." In the examples shown in FIGS. 5A and 5B, the first information A is printed on both the front surface 31a and the back surface 31b of the front flap portion 31. However, it is sufficient that the first information A is printed on at least one of the front surface 31a and the back surface 31b of the front flap portion 31.

[0031] The second information B is information related to the first information A printed on the front flap portion 31 that covers the middle flap portion 21 on which the second information B is printed. The second information B is displayed using letters, numbers, symbols, illustrations, photographs, two-dimensional barcodes, etc. Here, "related to the first information A" means, for example, an explanation or response to the first information A, detailed information or additional information about the first information A, promotional information related to the first information A, an issue of the same type as the first information A, etc.

[0032] In the example shown in FIG. 5B, the second information B is displayed on the front surface 21a of the middle door portion 21 using the following characters and the like: "Q2. How do you read this kanji?" "Butterfly" "The answer is here ▽". Furthermore, in the example shown in FIG. 5C, the second information B is displayed on the back surface 21b of the middle door portion 21 using the following characters and an illustration of a butterfly: "A2. Butterfly" "It's a butterfly". Note that in the examples shown in FIGS. 5B and 5C, the second information B is printed on both the front surface 21a and the back surface 21b of the middle door portion 21. However, it is sufficient that the second information B is printed on at least one of the front surface 21a and the back surface 21b of the middle door portion 21.

[0033] The third information C is information related to at least one of the second information B printed on the middle leaf section 21 that covers the information area 11 on which the third information C is printed, or the first information A printed on the front leaf section 31 that covers the middle leaf section 21. The third information C is displayed using letters, numbers, symbols, illustrations, photographs, two-dimensional barcodes, etc. Here, "related to at least one of the second information B or the first information A" means, for example, an explanation or response to the first information A or the second information B, detailed information or additional information on the first information A or the second information B, promotional information accompanying the first information A or the second information B, an issue in the same category as the first information A or the second information B, etc.

[0034] In the example shown in FIG. 5C, the third information C is shown by the words "Did you get both questions right? Now you're a Kanji expert too!!" and an illustration of a person.

[0035] The steps of the method for producing the sheet-shaped printed matter 1 of this embodiment will be explained below based on the flowchart shown in FIG. 6 and the explanatory diagrams shown in FIGS. 7A to 7F.

[0036] Step S1 is the printing process. That is, a perfecting press prints on both sides of the paper pulled from the roll paper. Printing is performed on the required printing area on the paper surface. The "required printing area" refers to, for example, the area corresponding to the front and back of the sheet-like printed material 1, the area exposed when the middle flap portion 21 and the front flap portion 31 are open, the area exposed when the middle seal piece 22 and the front seal piece 32 are peeled off, etc.

[0037] Step S2 is a process for forming the sheet material 2. The sheet material 2 is paper that will be used as the material for one sheet-like printed matter 1. In other words, one sheet-like printed matter 1 is produced from one sheet material 2. As shown in FIG. 7A, the sheet material 2 is formed by cutting out a strip of printed paper into individual sheet-like printed matter 1 pieces. Note that the printing on the sheet material 2 is omitted from FIGS. 7A to 7F.

[0038] The sheet material 2 is then divided into three rectangular regions at approximately equal intervals in the longitudinal direction. From the left end of Fig. 7A, the rectangular regions are the second sheet region 3C, the first sheet region 3A, and the intermediate sheet region 3B. The second sheet region 3C is the region that becomes the second sheet 30 when the sheet material 2 is made into the sheet-like printed material 1. The first sheet region 3A is the region that becomes the first sheet 10 when the sheet material 2 is made into the sheet-like printed material 1. The intermediate sheet region 3B is the region that becomes the intermediate sheet 20 when the sheet material 2 is made into the sheet-like printed material 1.

[0039] In addition, a second valley fold line 4B, which will be valley-folded in a subsequent process, is set between the second sheet region 3C and the first sheet region 3A. A first valley fold line 4A, which will be valley-folded in a subsequent process, is set between the first sheet region 3A and the intermediate sheet region 3B. Here, the surface of the sheet material 2 where the first valley fold line 4A and the second valley fold line 4B are exposed is called the front side, and the back side is called the back side.

[0040] Step S3 is an adhesive glue application step. That is, adhesive glue N1 is applied to the surface of the intermediate sheet region 3B of the sheet material 2. As shown in FIG. 7B, the adhesive glue N1 is applied to the area other than the area that will become the intermediate door portion 21 and a predetermined area around it, and to the area that will become the adhesive portion 24. The adhesive glue N1 forms a first adhesive layer 40.

[0041] Step S4 is a first valley folding step. That is, the sheet material 2 is valley-folded along the first valley fold line 4A as shown in Fig. 7C. As a result, the intermediate sheet region 3B is overlapped on the first sheet region 3A. Then, adhesive glue N1 is applied to the first sheet region 3A, and the intermediate sheet region 3B is adhered to the surface of the first sheet region 3A.

[0042] Step S5 is an adhesive paste application step. That is, adhesive paste N2 is applied to the front surface of the second sheet region 3C and the back surface of the middle sheet region 3B of the sheet material 2. As shown in Fig. 7D, adhesive paste N2 is applied to the area that will become the middle door section 21 and a predetermined area therearound, and to the area that will become the front door section 31 and a predetermined area therearound. A second adhesive layer 50 is formed by the adhesive paste N2.

[0043] Step S6 is a second valley folding process. That is, the sheet material 2 is valley folded at the second valley fold line 4B as shown in FIG. 7E. As a result, the second sheet region 3C is overlapped on the middle sheet region 3B. Then, the adhesive glue N2 adheres to each other, and the second sheet region 3C is adhered to the back surface of the middle sheet region 3B. As a result, the sheet material 2 has a three-layer structure in which the first sheet region 3A is arranged as the bottom layer, the middle sheet region 3B is arranged as the middle layer, and the second sheet region 3C is arranged as the top layer.

[0044] Step S7 is a cutting process. That is, as shown in Figures 7F and 8, cuts are made in the sheet material 2 at predetermined locations in the second sheet region 3C of the uppermost layer and the middle sheet region 3B of the middle layer. The cuts correspond to the middle cut line 23a, the middle fold line 23b, the cut line 25, the surface cut line 33a, the surface fold line 33b, and the cut line 35. As a result, the front door portion 31, the middle door portion 21, the front seal piece 32, and the middle seal piece 22 are formed simultaneously.

[0045] In the cutting process, a blade (not shown) for cutting the sheet material 2 is inserted perpendicularly from above the second sheet area 3C toward the paper surface. This causes the second sheet area 3C and the middle sheet area 3B to be torn simultaneously. As a result, as shown in FIG. 8, the middle cut line 23a and the surface cut line 33a overlap. Furthermore, although not shown, the middle fold line 23b and the surface fold line 33b overlap. In other words, the middle division line 23 and the surface division line 33 overlap. The middle door section 21 and the surface door section 31 then have the same shape. In the example shown in FIG. 8, the cut is made slightly on the surface of the first sheet area 3A. However, the cut may or may not be made in the first sheet area 3A as long as it does not tear the first sheet area 3A.

[0046] Step S8 is a cutting process. That is, the sheet material 2 is cut at removal sections 5A and 5B set on both side edges. The removal section 5A is a predetermined range including the boundary between the first sheet area 3A and the middle sheet area 3B, in other words, the first valley fold line 4A. The removal section 5B is a predetermined range including the boundary between the first sheet area 3A and the second sheet area 3C, in other words, the second valley fold line 4B. The cutting process and the cutting process may be performed simultaneously. As a result, the sheet-like printed matter 1 is produced.

[0047] The function of the sheet-shaped printed material 1 of this embodiment will be explained as follows.

[0048] The sheet-like printed matter 1 is formed by stacking a first sheet 10, an intermediate sheet 20, and a second sheet 30 in this order from the bottom up. Here, the intermediate sheet 20 is formed with an intermediate door section 21 that allows a portion of the intermediate sheet 20 to be opened and closed. The second sheet 30 is formed with a front door section 31 that covers the intermediate door section 21 and allows a portion of the second sheet 30 to be opened and closed.

[0049] Predetermined first information A is printed on the front flap portion 31. Second information B related to the first information A is printed on the middle flap portion 21. Furthermore, third information C related to at least one of the first information A and the second information B is printed in the information area 11 of the first sheet 10.

[0050] Therefore, when a user who has visually recognized the first information A by viewing the front flap portion 31 turns over the front flap portion 31 and opens a portion of the second sheet 30, the sheet-like printed material 1 can expose the middle flap portion 21 (see FIG. 5B). The sheet-like printed material 1 also allows the user to visually recognize the exposed middle flap portion 21 and recognize the second information B related to the first information A. Furthermore, when a user who has recognized the second information B turns over the middle flap portion 21 and opens a portion of the middle sheet 20, the sheet-like printed material 1 can expose the information area 11 (see FIG. 5C). The sheet-like printed material 1 also allows the user to visually recognize the information area 11 and recognize the third information C related to at least one of the first information A and the second information B.

[0051] In other words, by flipping over the front flap portion 31 and the middle flap portion 21 in order, the sheet-like printed material 1 can sequentially disclose second information B and third information C, which are related information related to the predetermined information, first information A. This allows the user to recognize the series of information in small pieces, compared to when the multiple pieces of information, first information A to third information C, are all disclosed at once. As a result, the sheet-like printed material 1 can increase the degree to which the series of information is recognized. Furthermore, by disclosing the series of information in order, the sheet-like printed material 1 can create a sense of anticipation in the user.

[0052] In the sheet-like printed matter 1, the intermediate sheet 20 is attached to the first sheet 10 via a first adhesive layer 40 having a non-adhesive region 41 facing the intermediate flap section 21. In addition, the second sheet 30 is attached to the intermediate sheet 20 via a second adhesive layer 50 having a non-adhesive region 51 facing the front flap section 31.

[0053] For this reason, in the sheet-like printed material 1, the adhesive that constitutes the first adhesive layer 40 is not applied to the middle door section 21. Therefore, the middle door section 21 is not attached to the first sheet 10. This allows the sheet-like printed material 1 to easily open the middle door section 21. Furthermore, the sheet-like printed material 1 can make the force required to open the middle door section 21 weaker than the force required to peel the middle sheet 20 from the first sheet 10. For this reason, the sheet-like printed material 1 can prevent the entire middle sheet 20 from peeling off from the first sheet 10 due to the force required to open the middle door section 21.

[0054] Furthermore, in the sheet-like printed material 1, the adhesive that constitutes the second adhesive layer 50 is not applied to the front flap portion 31. Therefore, the front flap portion 31 is not attached to the intermediate sheet 20. This allows the sheet-like printed material 1 to easily open the front flap portion 31. Furthermore, the sheet-like printed material 1 can make the force required to open the front flap portion 31 weaker than the force required to peel the second sheet 30 from the intermediate sheet 20. Therefore, the sheet-like printed material 1 can prevent the entire second sheet 30 from peeling off from the intermediate sheet 20 when the front flap portion 31 is opened.

[0055] Furthermore, in the sheet-like printed material 1, the middle partition line 23 and the surface partition line 33 overlap, and the middle door section 21 and the surface door section 31 have the same shape. Therefore, after folding the sheet material 2 into a laminated sheet, the middle door section 21 and the surface door section 31 can be simultaneously formed by making cuts in the top layer and middle layer in a single cutting process. This simplifies the manufacturing process and makes the sheet-like printed material 1 easy to manufacture. Furthermore, the sheet-like printed material 1 can prevent the middle door section 21 and the surface door section 31 from becoming misaligned.

[0056] Furthermore, the sheet-like printed material 1 has an adhesive portion 24 on the back surface 21b of the middle flap portion 21 that releasably adheres a part of the middle flap portion 21 to the first sheet 10.

[0057] Therefore, the sheet-like printed material 1 can temporarily fasten the middle flap section 21 to the first sheet 10. Furthermore, the sheet-like printed material 1 can prevent the middle flap section 21 from opening together with the front flap section 31 when the front flap section 31 is opened.

[0058] In the sheet-like printed product 1, an intermediate seal piece 22 is formed on the intermediate sheet 20, with the entire periphery being defined by a cut line 25. In addition, a front seal piece 32 is formed on the second sheet 30, with the entire periphery being defined by a cut line 35, and overlapping the intermediate seal piece 22. The intermediate seal piece 22 is peelable from the first sheet 10. Meanwhile, the front seal piece 32 is adhered to the intermediate seal piece 22.

[0059] As a result, the intermediate seal piece 22 can be peeled off from the first sheet 10 while the surface seal piece 32 remains attached. In other words, the sheet-like printed matter 1 can have two overlapping pieces of paper that can be removed from the sheet surface: the intermediate seal piece 22 and the surface seal piece 32. Therefore, the sheet-like printed matter 1 can make stickers or cards made of strong pieces of paper removable.

[0060] The above describes the sheet-like printed material 1 of the present disclosure, but the specific configuration is not limited to this embodiment, and design changes and additions are permitted as long as they do not deviate from the gist of the invention related to each claim.

[0061] That is, as shown in FIG. 9, of the intermediate dividing line 23 formed in the intermediate sheet 20 and dividing the intermediate door section 21, the intermediate cut line 23a may have an uncut portion 26. The uncut portion 26 is a portion that is provided halfway along the intermediate cut line 23a and does not tear the intermediate sheet 20. The position at which the uncut portion 26 is provided can be set arbitrarily. The proportion of the intermediate cut line 23a that the uncut portion 26 occupies is set to an extent that does not cause any interference with opening and closing the intermediate door section 21. In other words, the uncut portion 26 is set so that it can be broken along the intermediate dividing line 23 by the force that opens the intermediate door section 21.

[0062] In the sheet-like printed material 1, the middle leaf section 21 can be connected to the general section of the middle sheet 20 via the uncut section 26 at the middle cut line 23a. Therefore, the sheet-like printed material 1 can prevent the middle leaf section 21 from opening together with the front leaf section 31 when the front leaf section 31 is opened. Note that the "general section of the middle sheet 20" refers to the portion of the middle sheet 20 where the middle leaf section 21 and middle seal piece 22 are not formed. In addition, in the sheet-like printed material 1, the middle cut line 23a has the uncut section 26, so there is no need to provide an adhesive section 24 on the back surface 21b of the middle leaf section 21.

[0063] 10, the surface cut line 33a of the surface dividing line 33 that divides the surface door section 31 formed on the second sheet 30 may have an uncut portion 36. The uncut portion 36 is a portion that is provided midway along the surface cut line 33a and does not tear the second sheet 30. The position at which the uncut portion 36 is provided can be set arbitrarily. The proportion of the surface cut line 33a that the uncut portion 36 occupies is set to an extent that does not interfere with opening and closing the surface door section 31. In other words, the uncut portion 36 is set so that it can be broken along the surface dividing line 33 by the force used to open the surface door section 31.

[0064] In the sheet-like printed material 1, the surface cut lines 33a have uncut portions 36, so that the surface flap portion 31 can be connected to the general portion of the second sheet 30 via the uncut portions 36. Therefore, the sheet-like printed material 1 can prevent the surface flap portion 31 from lifting up or from being caught on items outside the sheet and opening. Note that the "general portion of the second sheet 30" refers to the portion of the second sheet 30 where the surface flap portion 31 and surface seal piece 32 are not formed.

[0065] Furthermore, in cases where the intermediate demarcation line 23 and the surface demarcation line 33 overlap and the uncut portion 26 and the uncut portion 36 also overlap, the intermediate demarcation line 23 and the surface demarcation line 33, including the uncut portion 26 and the uncut portion 36, can be formed simultaneously in a single cutting process.

[0066] Furthermore, the front door part 31 may be provided with an adhesive part 24 on the back surface 31b facing the intermediate sheet 20, which adhesive part 24 is removably adhered to the intermediate sheet 20. When the adhesive part 24 is provided on the back surface 31b of the front door part 31, it is possible to prevent the front door part 31 from lifting up or from being caught on an item outside the sheet and opening.

[0067] Furthermore, the adhesive portion 24 does not necessarily have to be provided on the middle door portion 21. Furthermore, different types of adhesive may be used for the adhesive glue that constitutes the first adhesive layer 40 and the adhesive glue that constitutes the adhesive portion 24. In particular, the first adhesive layer 40 may be made of glue that has a stronger adhesive strength than the adhesive portion 24.

[0068] Furthermore, the intermediate fold line 23b and the surface fold line 33b do not have to be formed by perforations. That is, the intermediate fold line 23b and the surface fold line 33b may be, for example, embossments or creases formed on the intermediate sheet 20 or the second sheet 30.

[0069] Furthermore, a plurality of stacked intermediate sheets 20 may be disposed between the first sheet 10 and the second sheet 30. In other words, the sheet-like printed matter 1 may include a printable first sheet 10 disposed in the bottom layer, a plurality of printable intermediate sheets 20 disposed in the middle layer and stacked, and a printable second sheet 30 disposed in the top layer.

[0070] In this case, a middle door section 21 is formed on each of the multiple middle sheets 20. The middle door sections 21 formed on each middle sheet 20 overlap each other. The middle sheets 20 are bonded to each other via a third adhesive layer made of an adhesive glue or glue. The third adhesive layer has non-adhesive areas where the middle door sections 21 face each other. The non-adhesive areas of the third adhesive layer are areas where the middle sheets 20 are not bonded to each other. In other words, even when multiple middle sheets 20 are stacked, glue is not applied to the back surfaces 21b of the middle door sections 21.

[0071] Furthermore, second information B related to the first information A or information related to the second information B printed on another intermediate leaf portion 21 is printed on the intermediate leaf portion 21 formed on each intermediate sheet 20.

[0072] As a result, even if the sheet-like printed material 1 has multiple intermediate sheets 20, it is possible to sequentially disclose related information that is related to predetermined information each time the intermediate flap section 21 is opened. Furthermore, the sheet-like printed material 1 can increase the number of intermediate flap sections 21 according to the number of intermediate sheets 20, thereby increasing the amount of information that can be disclosed.
