[Industrial applications]

 2. Description of the Related Art Conventionally, a sheet bag file, which is formed by binding a number of plastic bags into a book-like form, has been widely used as a file for putting documents, photographs, samples, etc. in a bag. The present invention relates to a bag file book which is convenient for stably storing sheets such as photographic printing paper among these bag files.

[0002]

[Prior art]

 Conventionally, bag files include those with an opening in the upward direction relative to the binding margin, those with an opening in the outer direction, and those with a horizontal insertion opening in the center stitching direction. It is said that a side-by-side bag file with an opening in the direction is more convenient because there is no risk of the contents falling when the file book is bound. When storing thin paper and thick sheets in these bag files, there is a drawback in that they move from the initially stored position. This drawback is not a problem for files that simply sort and organize materials, but the sheet bag file book is used as it is to see the stored sheets such as sample sample books and photo albums. In this case, the appearance of the storage sheets is not good if they are bent. In addition, if the bag file book is closed, it may even fall outside the bag if the bag file book is closed. As described above, the bag file book for a sheet having an opening inward is preferred by consumers, but it is complicated to manufacture. The inventor of the present invention has proposed a method for continuously and easily producing a laterally insertable bag sheet from the center, which has been considered difficult to produce, in Japanese Patent Publication No. 1-36798. However, in the case of this bag sheet as well, in the case of a bag file formed by stacking a plurality of sheets, for example, when the sample book or the photographic paper is inserted into the bag and used as an album, the photographic paper or the like is in the bag. There is a case to move and shift. In particular, recently, since it is possible to freely select panorama size and normal size photos for shooting, if the size of the bag body of the album bag sheet is adopted according to the panorama size, one normal size photo will be taken. Although two pieces fit in the bag, they move inside the bag, and the two pieces overlap or become slanted, which has the drawback that the album does not look good. To prevent this, you can attach an adhesive to the back of the photographic paper and attach it to the core sheet, but in this case, the operation of exchanging the photos becomes complicated, and the exchanging of the received photos is not possible. You lose the advantage of bag files that they are simple.

[0003]

[Problems to be solved by the device]

 The present invention provides a bag file book in which sheets and the like stored in the bag do not shift, for example, a file book suitable for viewing externally stored items such as albums that can be stored with photographic paper fixed. The purpose is to do.

The present invention will be described in more detail with reference to the drawings of the embodiments. As shown in FIG. 3 (plan view) and FIG. 4 (cross-sectional view), the bag sheet used in the bag file book of the embodiment of the present invention includes the left and right back surfaces of the core sheet 1 and the bag films 2 and 2 ′. There are a total of four sheet bag body portions formed by the upper and lower fusion edges 4, 4'and the fold lines 6, 6'of the bag film 2, 2 '. The sheet bag portion of the present invention has a shape of two rectangular films or a bag shape in which three sides are closed and one side is opened in a state where the sheets are superposed, and a thin piece of paper or the like is placed between the films. Can be inserted. As shown in FIGS. 3 and 4, the core material sheet 1 constitutes the core of the bag sheet, and the height of the upper and lower edges 4 and 4 ′ and the width of the right and left 8 and 8 ′ in FIG. It is a sheet that has. The core sheet of the present invention is a thermoplastic sheet, and can be used with a thin film or a thick sheet. The core sheet can be made opaque by coloring or the like.

In particular, when it is used for an album, it is not necessary to make the core material sheet 1 opaque because it becomes opaque on the back side of the photographic paper placed on the opposite side of the bag. The bag films 2 and 2 ′ are bent to the left and right of the core sheet 1 so as to wrap the ends 8 and 8 ′ of the core sheet 1. The ends 5, 5'of the bag film 2, 2'extend to the line AB to form the opening edge of the bag. At the upper and lower edges 4, 4'of the bag films 2, 2 ', three core films 1 and two bag films 2, 2'of the front and back are fused at the same time. The bag films 2 and 2'are thin thermoplastic plastic films having a thickness of about 20 to 200 .mu.m, and need to be transparent in order to see the stored printing paper as it is. The material is not particularly limited as long as it is a thermoplastic resin film having a certain strength, and polyethylene, polypropylene, polyester, nylon, etc. can be preferably used. Between the opening edges 5, 5'of the bag body on both sides of the bag sheet, there is a central portion for fusing where only one core sheet 1 exists, and this portion should be fused and fixed to the cover sheet. You can

In this embodiment, the surface-roughened ink layers 7 and 7 ′ are coated near the opening edge of the bag film so that writing is possible. In the bag sheet of the present invention, the heat-sensitive adhesive layer 3, 3'or the anti-fusion agent 3, 3'is provided on all or part of the three edges of the bag body on the left and right AC, CD and DB lines in FIG. The feature is that it is provided. The heat-sensitive adhesive layer and the anti-fusing agent layer can be provided within a range of about 3 to 10 mm from the edge of the bag. In the case of the embodiment shown in FIG. 3, the heat-sensitive adhesive layers 3, 3'are provided on the edges of the left and right CDs. This is because heat-sensitive adhesive is applied to the positions corresponding to the left and right folds 6 and 6'of the bag film 2 and 2 ', a bag sheet is prepared, and then heat-sealed from the outside of the fold to perform heat-sensitive adhesion. With the agent layer, the ends of the bag films 2 and 2'and the core material sheet 1 are separated by about 1 to 3 mm from the inner end of the heat-sensitive adhesive coating layer, for example, with a width of 2 to 9 mm from the end of the bag. Set.

In this case, heat sealing is preferably performed outside the lines 9 and 9 ′ inside the heat-sensitive adhesive layer, and when the heat-sensitive adhesive layer adheres too strongly, the sheet stored in the bag is fixed. It is desirable to control the heat-sealing temperature to a low level to keep the adhesive strength low, as the effect of this will decrease. In addition, a heat-sensitive adhesive, such as wax, which reduces the adhesive force can be added to obtain an adhesive strength suitable for the present invention. The width of the heat-sensitive adhesive layers 3, 3'is properly selected, but is usually 3 to 10 mm, preferably 5 to 10 mm. As the heat-sensitive adhesive, a polymer which is melted by heat and adheres when cooled, for example, a heat-sensitive adhesive such as ethylene-vinyl acetate copolymer, polyamide or polyester can be used. To this, a rosin, a pinene-based resin, or the like can be added as a tackifier. As another aspect of the present invention, an anti-fusing agent may be applied in place of the heat-sensitive adhesive layers 3, 3'of the previous aspect. The anti-fusing agent has a function of preventing the two films from being fused and fixed when heat-sealed from the outside of the two thermoplastic films. In this case, after heat sealing, the film of the heat sealed portion can be easily peeled off with a finger.

As the anti-fusing agent, any agent having the above-mentioned action can be used without particular limitation, but those which dry after application, for example, printing ink, drying oil, wax and the like are desirable. If an anti-fusing agent is used, the adhesiveness will decrease if the usual amount used for anti-fusing is applied, so either apply a thin anti-fusing agent, or heat it slightly strongly during heat sealing. Then, it is desirable to adhere them in a semi-molten state. Also in this case, it is desirable to heat seal the inner side of the edge of the anti-fusing agent by 1 to 3 mm. The pressure-sensitive adhesive layer or the anti-fusing agent layer of the present invention is provided along the edge of the bag body, but the mode is not limited to that shown in FIG. 3, for example, as shown on the right side of FIG. A mode in which it is provided on all the edges of CD and DB, a mode in which it is provided in the upper and lower edges of AC and DB as shown in the left side of FIG. 5, a mode in which it is provided in the upper and lower corners on the right side of FIG. It is possible to increase the number of circular spots.

A plurality of bag sheets of the present invention can be laminated and fused together on the cover sheet 11 at the same time to form a bag file book as shown in FIGS. When a thick plastic sheet is used as the cover sheet of the present invention, a plurality of bag sheets are placed on the cover sheet, and the central portion is directly fused by ultrasonic sealing or high frequency sealing or other fusing method. For example, all bag sheets and cover sheets can be fused at once. As a fusing method, ultrasonic sealing is preferable in terms of fusing strength and finished appearance. In the embodiment shown in FIGS. 1 and 2, thick paper is used for the cover sheet 11. In this case, a thick thermoplastic sheet 12 is adhered to the central portion of the paper sheet 11 with an adhesive. The bag file book can be obtained by fusing the bag sheet laminate to the plastic sheet in the same manner as above. It is preferable to use a paper-made cover sheet because it is more flexible, the structural function of the cover sheet is excellent, and beautiful printing is possible.

FIG. 1 shows an embodiment using the bag sheet of FIG. When printing paper into the bag body of this bag file book, for example, put the printing paper having a size half the width of the bag through the opening edge 5, and the tip of the paper is a heat-sensitive adhesive layer or anti-fusing agent. When you hit the layer 3 a little harder when you hit it, the edges of the photographic paper bite into the heat-sensitive adhesive layer and are fixed. Even if the page of the bag file is turned over in this state, the photographic printing paper is stored in the original storage position without moving straight inside the bag. The bag sheet of the bag file book of the present invention can be manufactured by applying a heat-sensitive adhesive or an anti-fusion agent to a corresponding portion of the bag film in the method described in the above Japanese Patent Publication No. 1-36798. it can. In this production, the heat-sensitive adhesive, the printing ink and the like are applied and then dried, so that the production method can be applied without any trouble. In the bag file book of the present invention, the case where the opening of the bag is outward with respect to the binding margin is as shown in the embodiment of FIG. 7, in which the inside of the bag film on both sides of the core sheet is heat-sealed. Since there is an opening 5 in the outward direction with respect to the binding margin G, sheets can be inserted from the outside.

Also in this case, a heat-sensitive adhesive layer or a fusion preventing agent layer similar to the above can be provided on all or part of the bottom edge E or the side edge F of the bag in the same manner as in the above embodiment. The central binding margin G of this bag sheet can be fused with the cover sheet to form a sheet bag file book in the same manner as in the above embodiment. Similarly, with respect to the binding margin G, the embodiment of the present invention having openings in the upper and lower edge directions is, as shown in FIG. 8, a heat-sensitive adhesive layer or a fusion bonding agent on the bottom edge E or the side edge F of the bag body. An inhibitor layer can be provided as well. The bag sheet of FIG. 8 is a simple film sheet in which one film is heat-sealed with a line H, and one bag sheet has one bag body. The binding margin G can be fused to form a sheet bag file book. The bag file sheet used in the bag file book of the present invention has an opening on the outer side or the upper and lower edges, is made of a plastic film and has a bag body portion, and any shape can be used as long as it has a binding margin portion. However, it is particularly preferable that the core sheet has four bag portions on both left and right sides. Further, as shown in FIG. 8, a single page having one bag on each page can be appropriately used because of its simple manufacture. In the case of the bag file book of these modes, when the sheet is stored by pressing the edge of the sheet against the heat-sensitive adhesive layer or the anti-fusing agent layer, the bag film holding force is improved. The position of the storage sheet can be kept in the initial storage position.

[Effect of device]

 In the bag file book of the present invention, for example, when a sheet such as a photographic printing paper is stored, even if the sheet has a size smaller than the bag body, the position of the sheet does not shift and the sheet is kept in the initial storage state. It has the advantage that it can be stored in. Further, there is an advantage in that the effect of position preservation does not deteriorate even if the storage and the extraction are repeated to the extent that they are normally performed. Because of this advantage, it is most suitable as a photo album and sample book, and its demand is much useful.
