On the upper side of the cover cover body 1, the outer sheet 2 forms an upper insertion port 10 that can be opened wide by opening the entire upper end portion 14 of the cover cover body 1, and the outer sheet 2 is formed outside through the upper insertion port 10. A cover pocket portion 11 is formed between the sheet 2 and the inner sheet 3 so that an original cover 4 having the same size as the cover cover body 1 or slightly shorter on the long side can be placed. The inner sheet 3 is formed with a central vertical folding line 33 extending in the vertical direction over the entire length in the center, and cover parts 31 and 32 are provided on the left and right sides of the central vertical folding line 33 as a boundary. The outer sheet 2 is formed with a central longitudinal folding line 23 extending in the longitudinal direction over the entire length in the center, and cover parts 21 and 22 are provided on the left and right sides of the central longitudinal folding line 23. The central longitudinal folding lines 23 and 33 allow the inner sheet 3 and the outer sheet 2 to be folded inward, so that the cover cover body 1 can be easily opened and folded. Examples of the booklet 5 include a notebook, a notebook, an album, and a book.

  Referring to FIG. 5, the inner sheet 3 is made of a transparent or opaque resin sheet that is formed in a rectangular shape as a whole. The inner sheet 3 is formed at the upper left and right sides with the horizontal folding bars 34 a and 35 a as a boundary. 2 horizontal folding bars) 34a and 35a have left and right upper folded pieces 34 and 35 folded back to the inner surface side. The inner sheet 3 is not limited to a resin sheet, and may be formed from a material sheet such as paper or leather. Referring to FIG. 6, the outer sheet 2 is made of a highly transparent resin sheet that is formed in a rectangular shape as a whole, and is the same as the inner sheet 3 or a sheet main body portion 20 that is formed to have a slightly longer left-right width. Left and right horizontal folded pieces 24 and 25 formed on the left and right of the sheet main body 20 with the vertical folding lines 24a and 25a as boundaries, and folded back to the inner surface side by the vertical folding lines 24a and 25a, and the lower end of the sheet main body 20 Left and right lower folding pieces 26 and 27 are formed on the left and right sides of the horizontal folding bars (first lateral folding bars) 26a and 27a and folded back to the inner surface side by the horizontal folding bars 26a and 27a. The sheet main body 20 has cover parts 21 and 22 on the left and right with the central longitudinal folding line 23 as a boundary.

Then, the inner sheet 3 is arranged on the inner surface of the outer sheet 2 and superimposed on the sheet main body 20, and the left and right lateral folding pieces 24, 25 of the outer sheet 2 are folded to the inner surface side by the vertical folding lines 24a, 25a. It is arranged on the inner surface of the inner sheet 3. The folded left and right horizontal folded pieces 24, 25 form joint portions 61, 62 in which the base end portions along the longitudinal folding lines 24a, 25a are joined to the left and right edge portions of the inner sheet 3 in the longitudinal direction by welding. (In Fig. 3, ○
(See the enlarged section surrounded by). Referring also to FIG. 7, the left and right lower folded piece portions 26, 27 of the outer sheet 2 are folded back to the inner surface side by the lateral folding lines 26 a, 27 a, and the left and right lateral folded piece portions 24, 25, the joint portions 63 and 64 are formed by joining the front end portions thereof to the lateral folding pieces 24 and 25 by welding over the entire length in the lateral direction (see FIG. 7B). The left and right upper folded pieces 34, 35 of the inner sheet 3 are arranged on the left and right lateral folded pieces 24, 25 that have been folded back to the inner surface side by the horizontal folding lines 34 a, 35 a, and their front ends. Joined portions 65 and 66 are formed by welding the side folded portions 24 and 25 in the lateral direction over the entire length by welding (see FIG. 7A).

  In this way, the pair of left and right inner pocket portions 12, 13 for inserting the front cover 51 and the back cover 52 of the booklet 5 between the inner sheet 3 by the left and right laterally folded pieces 24, 25 of the outer sheet 2 are formed. It is formed. At the same time, on the upper side of the cover cover body 1, the left and right upper folded pieces 34 and 35 of the inner sheet 3 are welded to the left and right lateral folded pieces 24 and 25 of the outer sheet 2 (joint portions 65 and 66). Therefore, the outer sheet 2 forms an upper insertion port 10 that can be opened widely by opening the entire upper end portion 14 of the cover cover body 1, and the outer sheet 2 and the inner sheet 3 are formed through the upper insertion port 10. A cover pocket portion 11 that allows an original cover 4 having substantially the same size as the cover cover body 1 to be disposed is formed between the cover cover portion 1 and the cover cover portion 1.

  In the inner pocket portions 12 and 13, the upper folded piece portions 34 and 35 and the lower folded piece portions 26 and 27 are arranged on the outer surface of the lateral folded piece portions 24 and 25 and are welded (joined portions 63, 64, 65, 66). Therefore, there is no portion that is caught in the inner pocket portions 12 and 13, and the front cover 51 and the back cover 52 of the booklet 5 can be smoothly inserted into the inner pocket portions 12 and 13 without being caught. On the lower side of the cover 1, the left and right lower folded pieces 26 and 27 of the outer sheet 2 are welded to the left and right lateral folded pieces 24 and 25 of the outer sheet 2 (joining portions 63 and 64). The lower end portion 15 of the cover pocket portion 11 is closed at the left and right portions by the lower folded piece portions 26 and 27 to prevent the original cover 4 from falling off. In the central portion of the lower end portion 15 of the cover pocket portion 11, the lower folded piece portions 26 and 27 are not disposed, and the inner sheet 3 and the outer sheet 2 can be separated (see FIG. 7B). When opening the insertion port 10, the inner sheet 3 and the outer sheet 2 at the center part of the lower end are separated from each other, so that the upper insertion port 10 is easily opened.

  According to the cover cover body 1 having the above configuration, the outer sheet 2 forms the upper insertion port 10 that can be opened widely on the upper side of the cover cover body 1. The original cover 4 having a size substantially the same as that of the cover body 1 can be easily inserted into and replaced with the inside of the cover pocket portion 11 covering the entire outer surface of the cover cover body 1. Therefore, an arbitrary original cover 4 can be easily arranged on the entire outer surface of the cover cover body 1 and the cover design of the entire outer surface of the cover cover body 1 can be easily changed through the transparent outer sheet 2.

  As the original cover 4, various design data such as original photo data, illustration data, a company logo, and a company image can be printed on a desired sheet by a printer. The paper size of the original cover 4 is a constant size that matches the standard size (JISP0138) of the paper such as row A and row B. In the booklet such as a notebook, the front cover 51 and the back cover 52 have a half size or a short side of the original cover 4 of a certain size slightly shorter than the half size. For example, if the cover pocket portion 11 has a size that can accommodate A4 size paper, the design data can be printed on A4 size paper and used as the original cover 4. Therefore, the user can easily change the cover cover body 1 to be attached to the booklet 5 to his / her favorite cover design, and the company can use the cover cover body 1 to be attached to the booklet 5 for example. Appropriately dressed as a cover design that represents a corporate image, etc., can be used for novelty products, etc., and can be used effectively as its own advertising media.

Further, since the sheet main body portion 20 of the outer sheet 2 is formed in substantially the same size as the inner sheet 3, it becomes an outer member of the cover pocket portion 11 and constitutes the outer surface of the cover cover body 1. The inner sheet 3 becomes an inner member of the cover pocket portion 11. The left and right laterally folded piece portions 24 and 25 of the outer sheet 2 are joined to the left and right edge portions of the inner sheet 3 by welding (joined portions 61 and 62) along the longitudinal folding lines 24a and 25a. The left and right joint portions 61 and 62 are hidden by the original cover 4 disposed in the cover pocket portion 11 so that the transparent outer sheet 2 is not visible from the outside. That is, the joining portions 61 and 62 of the left and right laterally folded piece portions 24 and 25 are formed between the laterally folded piece portions 24 and 25 and the inner sheet 3, and the joined portion 61 is formed on the sheet main body portion 20 of the outer sheet 2. , 62 are not formed.
Therefore, as shown in FIG. 8, when the original cover 4 is arranged in the cover pocket portion 11, the left and right joint portions 61 and 62 are arranged on the back side of the original cover 4 and are outside the cover pocket portion 11. Even if the transparent outer sheet 2 is watermarked, it is hidden behind the original cover 4 and is not visible. Therefore, from the outside of the cover cover 1, the joining portions 61 and 62 do not overlap the original cover 4, and the original cover 4 is visually recognized through the transparent outer sheet 2 and looks good.

  Further, in the left and right inner pocket portions 12 and 13, the joint portions 63, 64, 65 and 66 in the left and right lower folded pieces 26 and 27 and the upper folded pieces 34 and 35 are the left and right lateral folded pieces of the outer sheet 2. It is formed on the upper surface of the portions 24 and 25 and is not formed on the sheet main body portion 20 of the outer sheet 2. Accordingly, all the joint portions 61, 62, 63, 64, 65 and 66 for forming the inner pocket portions 12 and 13 are not formed in the sheet main body portion 20 of the outer sheet 2. Therefore, from the outside of the cover cover body 1, all of the joining portions 61, 62, 63, 64, 65, 66 do not overlap the original cover 4, but only the original cover 4 is transparent through the transparent outer sheet 2. It is visually recognized and looks very nice. As a result, the booklets 5 fitted with the cover cover body 1 appear to be mounted only by the original cover 4 in appearance, and the design of the original cover 4 that can be replaced is not impaired. Design properties can be exhibited sufficiently.

(Embodiment 2)
As shown in FIGS. 9 and 10, the cover cover body 1 </ b> A according to the second embodiment is formed by a single transparent sheet body 101 in which the outer sheet 2 and the inner sheet 3 are integrally provided. At the lower end 15 of the cover body 1A, the outer sheet 2 and the inner sheet 3 are integrally connected by connecting parts 120a and 120b. In addition, although the sheet | seat body 101 is formed with a transparent resin sheet, the part used as the inner sheet | seat 3 may be made opaque or semi-transparent by printing etc. Further, the cover cover body 1A is provided with a communication hole h that communicates with the cover pocket portion 11 at the lower end portion of the central longitudinal folding line y in the spread state. As a result, even after the original cover 4 is stored in the cover pocket portion 11, the lower air in the cover pocket portion 11 escapes to the outside from the communication hole h, and the outer sheet 2 can be prevented from being lifted. Also gets better. When the cover sheet 1A is manufactured, when the outer sheet 2 and the inner sheet 3 that are integrally formed are folded, the air between the sheets 2 and 3 escapes to the outside from the communication hole h. Even in the vicinity of bending with the inner sheet 3 (near the connecting portions 120a and 12b), both the sheets 2 and 3 can be easily overlapped, and the subsequent welding operation and the like of each portion can be performed smoothly. Note that the other configurations and operational effects of the cover cover body 1A of the second embodiment are basically the same as those of the first embodiment.

Next, a method for manufacturing the cover 1A of the second embodiment will be described.
As a first step, a single transparent sheet body 101 having the following configuration is formed.
As shown in FIG. 10, the sheet body 101 includes a first sheet portion 102 that becomes the outer sheet 2 and a second sheet portion 103 that becomes the inner sheet 3. The first sheet portion 102 includes a rectangular sheet main body portion 20, and vertically long rectangular lateral folding pieces 24 and 25 that are foldable at the left and right ends, which are short sides of the sheet main body portion 20, by a vertical folding line y 1. The second sheet portion 103 is formed in one piece, and has the same shape and size as the sheet main body portion 20 of the first sheet portion 102, and can be bent at the lower end of the sheet main body portion 20 by the first lateral folding line x1. It is integrally formed. The first sheet portion 102 further has left and right lower ends of the sheet main body portion 20 with left and right connection portions 120a on the center side from the position of the longitudinal folding line y1 and left and right sides of the lateral folding pieces 24 and 25. In the range of a length shorter than the width, U-shaped cuts k are provided in the second sheet portion 103 to form horizontally folded lower folded pieces 26 and 27 that can be bent by the first lateral folding line x1. The second sheet portion 103 further has the same shape and size as the lower folded piece portions 26 and 27 on the left and right sides of the lower end on the side facing the first lateral folding line x1, and faces the lower folded piece portions 26 and 27. The horizontally long rectangular upper folded pieces 34 and 35 that can be bent by the second horizontal folding line x2 are formed at the position where the second folding line x2 is placed.

  Further, the sheet body 101 is formed with a central longitudinal folding line y extending over the entire length in the longitudinal direction so as to be divided into two equal parts to the left and right. In the cover cover body 1A completed by the central vertical folding line y, the inner sheet 3 and the outer sheet 2 can be folded inward along the central vertical folding line y, so that the spread and folding can be facilitated. In addition, the formation process of the center longitudinal folding line y does not need to be performed in this 1st process, and may be implemented somewhere in the manufacturing process of 1 A of cover-cover bodies.

  In addition, a communication hole h is formed at an intermediate position of the first lateral folding line x1 that connects the first sheet portion 102 and the second sheet portion 103. The shape of the communication hole h when forming the sheet body 101 is preferably, for example, a cross hole shape, but is not limited thereto, and may be any shape such as a polygonal hole such as a round hole or a square hole. Can do. The position of the communication hole h is located at the lower corner of the back when the completed cover cover body 1A is folded along the central longitudinal folding line y, so that the sheet is formed in an R shape in this folded state. The shape of the communication hole h when forming in the body 101 is preferably a cross hole shape in which the corners of the inner diameter are R-shaped and four tips extending outward are pointed. However, if the shape of the communication hole h is a round hole, it can be easily formed without worrying about the directionality like a cross hole.

  Further, when the sheet body 101 is formed, the four corners 20k of the sheet body portion 20, the upper and lower corners 25k on the side of the sheet body portion 20 connected to the left and right lateral folding pieces 24, 25, and the four corners 103k of the second sheet portion 103 are , Formed in an R shape. As a result, the four corners of the completed cover cover body 1A have an R-shaped chamfered shape.

  In order to form the sheet body 101 having the above-described configuration in the first step, for example, each shape of the sheet body 101 is cut by cutting, cutting, fusing, or the like with a blade such as a Thomson blade or a hot blade. Each folding line y, y1, x1, x2 can be formed by pressing and drawing with a pressing tool such as a pressing blade or a roll blade.

  In the second step, as shown in FIGS. 11A, 11B, and 12C, in the sheet body 101, the second sheet portion 103 is folded back along the first lateral folding line x1 to form the first sheet portion. 102 (see FIGS. 11 (a) and 11 (b)), and then the left and right lateral folding pieces 24 and 25 of the first sheet portion 102 are folded along the longitudinal folding line y1 to be second. Overlay on the sheet portion 103 (see FIG. 12C).

  In the third step, as shown in FIG. 12 (d), the base end portion along the vertical folding line y1 in the left and right lateral folding pieces 24 and 25 of the first sheet portion 102 superimposed on the second sheet portion 103. Is welded only to the second sheet portion 103. As a result, the second sheet portion 103 and the sheet main body portion 20 of the first sheet portion 102 disposed on the rear side (outside) of the second sheet portion 103 are not joined. An upper insertion port 10 is formed to allow opening of the entire upper end portion overlapped with the second sheet portion 103, and the first sheet portion 102 (outer sheet 2) and the second sheet portion 103 ( A cover pocket portion 11 capable of storing a single original cover 4 between the inner cover 3) and the inner sheet 3) is formed on the outer surface side of the cover cover body 1A (see FIG. 9).

  In the third step, in the welded portions 61 and 62, the sheet main body portion 20 of the first sheet portion 102, the second sheet portion 103, and the laterally folded piece portions 24 and 25 of the first sheet portion 102 are sequentially overlapped with each other. However, by adjusting the jig temperature, pressing time, pressing force, etc. of the welding jig such as a hot blade pressed from the side of the uppermost horizontal folded piece 24, 25, the three layers (sheet body portion) 20, only the upper two layers (the second sheet portion 103 and the laterally folded piece portions 24, 25) can be welded without being welded to the second sheet portion 103 and the laterally folded piece portions 24, 25).

  However, the present invention is not limited to such a welding method, and other welding methods may be performed. For example, a thin patch plate is disposed between the sheet main body portion 20 and the second sheet portion 103, or the lowermost sheet. A welding jig may be pressed from the side of the uppermost horizontal folded pieces 24 and 25 by disposing a heat sink under the main body 20 or the like. In the welding operation in the third step, the left and right lateral folding pieces 24 and 25 are welded separately on the left and right, but may be welded on the left and right simultaneously. In the case where the left and right laterally folded pieces 24 and 25 are welded separately, an apparatus having one welding jig can be used, so that the welding apparatus can be simply configured and the equipment cost can be reduced. it can. Further, when the left and right lateral folded pieces 24 and 25 are welded separately, the second step and the third step can be performed for each of the left and right lateral folded pieces 24 and 25.

  In the fourth step, as shown in FIGS. 12D and 13E, the left and right lower folded pieces 26 and 27 of the first sheet portion 102 and the left and right upper folded pieces 34 of the second sheet portion 103 are formed. , 35 are folded back along the first lateral folding line x1 and the second lateral folding line x2, respectively, and overlapped on the lateral folding pieces 24, 25 of the first sheet portion 102.

  In the fifth step, as shown in FIG. 13 (f), the left and right lower folded piece portions 26, 27 superimposed on the lateral folded piece portions 24, 25 have their tip portions laterally folded along the left-right width direction. , 25, and the left and right upper folded pieces 34, 35 superimposed on the lateral folded pieces 24, 25 are welded only to the lateral folded pieces 24, 25 along the lateral width direction. . As a result, the laterally folded piece portions 24 and 25 and the lower folded piece portions 26 and 27 are formed on the side of the second sheet portion 103 where the sheet main body portion 20 of the first sheet portion 102 is not disposed (the inner surface side of the cover cover body 1A). A pair of left and right inner pockets 12 and 13 into which the front cover 51 and the back cover 52 of the booklet 5 are respectively inserted are formed by the upper folded pieces 34 and 35 (see FIG. 9).

  In the fifth step, at the welded portions 65 and 66 of the upper folded piece portions 34 and 35, the sheet main body portion 20 of the first sheet portion 102, the second sheet portion 103, the laterally folded piece portion 24 of the first sheet portion 102, 25, and further, the upper folded pieces 34 and 35 are in four layers which are sequentially overlapped. On the other hand, in the welded portions 63 and 64 of the lower folded pieces 26 and 27, the second sheet portion 103 is notched by the notch k. Therefore, the sheet main body portion 20 of the first sheet portion 102, the laterally folded piece portions 24 and 25 of the first sheet portion 102, and further the lower folded piece portions 26 and 27 are in three layers.

  Also in this case, similar to the above-described third step, the jig temperature and pressure in a welding jig such as a hot blade pressed from the upper folded piece portions 34, 35 and the lower folded piece portions 26, 27 on the uppermost layer. By adjusting time, pressing force, etc., only the upper two layers (upper folding pieces 34, 35 and lateral folding pieces 24, 25, lower folding pieces 26, 27 and lateral folding pieces 24, 25) Can be welded. However, it is not limited to such a welding method, and other welding methods may be performed in the same manner as in the third step described above.

  The welding in the fifth step is performed by separately welding the left and right upper folded pieces 34 and 35 and the left and right lower folded pieces 26 and 27, but the lower folded pieces 26 and 27 and the upper The folded pieces 34 and 35 may be welded simultaneously. In the case where the lower folded piece portions 26 and 27 and the upper folded piece portions 34 and 35 are welded separately, an apparatus having one welding jig can be used, so that the welding apparatus can be simply configured. Equipment costs can be reduced. When the lower folded piece portions 26 and 27 and the upper folded piece portions 34 and 35 are welded separately, the fourth and fifth steps are performed for each of the lower folded piece portions 26 and 27 and the upper folded piece portions 34 and 35. And can be done. Alternatively, the lower folded pieces 26 and 27 and the upper folded pieces 34 and 35 may be welded separately on the right and left sides.

In the above manufacturing method, rather than the steps (fourth and fifth steps) for welding between the horizontal folded piece portions 24, 25 and the lower folded piece portions 26, 27 and the upper folded piece portions 34, 35. The process (2nd, 3rd process) for welding the 2nd sheet | seat part 103 and the horizontal folding piece parts 24 and 25 previously is performed. Thereby, when welding between the horizontal folding piece parts 24 and 25, the lower folding piece parts 26 and 27, and the upper folding piece parts 34 and 35 (4th, 5th process), the horizontal folding piece parts 24 and 25 are provided. And the lower folded piece portions 26 and 27 and the upper folded piece portions 34 and 35 can be easily aligned, and misalignment, welding errors, and the like can be prevented. In addition, the process (4th, 5th process) for welding between the horizontal folding piece parts 24 and 25, the lower folding piece parts 26 and 27, and the upper folding piece parts 34 and 35 is the 2nd sheet | seat part 103. And the laterally folded piece portions 24 and 25 may be performed prior to the steps for welding (second and third steps).
By performing the above manufacturing process, the cover 1A shown in FIG. 9 is produced.
