Description

[Detailed description of the invention]

[0001]

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

[0002]

2. Description of the Related Art Heretofore, bag files include those having an opening upward in the binding margin, those having an opening outward, and those having a horizontal insertion opening in the center binding direction. However, it is said that a bag file of the horizontal insertion type having an opening in the center direction is more convenient because there is no danger of the contents dropping when the file book is bound. When thin papers and thick sheets are stored in these bag files, there is a drawback that they move from the initially stored position. This drawback is not a problem for files that simply sort and organize materials.However, if a sheet bag file book is used to view stored sheets as they are, such as a sample sample book or photo album, etc. If the storage sheets are bent, the appearance is poor. If the bag file book is closed or the bag file book is closed, it may fall out of the bag if the bag file book is closed. As described above, a bag file book for a sheet having an opening in the inward direction is preferred by consumers, but the production is complicated. The present inventor has proposed a method for continuously and easily manufacturing a laterally inserted bag sheet from the center, which was considered difficult to manufacture, in Japanese Patent Publication No. 1-367.
No. 98 proposes this. However, even in the case of a bag file created by binding a large number of sheets in this bag sheet, for example, when the sample book or photographic paper is inserted into the bag and used as an album, the photographic paper or the like moves in the bag. There are times when it shifts. In particular, recently, since a photograph can be freely selected between a panorama size and a normal size photograph, if the size of the bag of the bag sheet for the album is adopted according to the panorama size, the normal size photograph becomes one. Although two sheets are put in the bag, they move inside the bag, and the two sheets are overlapped or skewed. To prevent this, it is possible to attach an adhesive to the back of the photographic paper and attach it to the core sheet, but in this case, the operation of replacing photos becomes complicated, and it is easy to replace stored photos You will lose the benefits of the bag file.

[0003]

SUMMARY OF THE INVENTION The present invention is directed to a bag file book in which sheets and the like stored in a bag body do not shift, for example, a fixed storage such as an album in which photographic paper is fixed and can be stored. It is an object of the present invention to provide a file book suitable for use in viewing a file from outside.

[0004]

Means for Solving the Problems The present inventor has proposed that the sheets stored in the bag of the bag file book having the above-mentioned shape are sandwiched between two bag films. Paying attention to the fact that the stored thick sheet does not shift or fall inside the bag as long as the edge is fixed with a weak force, a mechanism to lightly hold the sheet edge is provided at the end of the bag. In this way, the position of the stored items is stabilized. That is, the present invention consists of the following items.

(1) As a three-layer structure in which thin films are arranged on both sides of the core material sheet in a U-shaped cross section on both sides with a space area parallel to the center of the core material sheet, the upper edge of the three-layer structure and A core material sheet and a bag film are fused at a lower edge, and a bag body portion formed between the core material sheet and the bag film, the bag body portion having an opening toward a center portion is formed into a core material. Coating both sides of the core sheet at the inner edge of the bag body portion of the bag sheet having at least four on the left and right sides of the sheet and the left and right sides thereof and the bag film at positions corresponding to the left and right bag folds of the bag film.

Bag file book for fixed sheets. (2) The sheet bag file book according to (1), wherein the cover is obtained by bonding a plastic sheet to a central portion of a paper sheet. (3) As a three-layer structure in which thin films are arranged on the left and right sides in a U-shaped cross-sectional structure on both sides of the core material sheet with a space parallel to the center of the core material sheet, the upper and lower edges of the three-layer structure are used. A bag body portion formed by fusing the core material sheet and the bag film and being formed between the core material sheet and the bag film, and having an opening toward the center, is formed on the left and right sides of the core material sheet. And both sides of the core sheet at the inner edge of the bag portion having at least four bag sheets on the left and right sides and the bag film are applied to positions corresponding to the left and right bag folds of the bag film. By heat sealing the portion outside the inner line of the anti-adhesive agent layer, a plurality of semi-fused ones are stacked and laminated on a cover sheet, and the central part of the laminated bag sheet is thickened by fusion. Bag file book for sheets fixed on the cover. (4) The sheet bag file book according to (3), wherein the cover is formed by bonding a plastic sheet to a central portion of the paper sheet. (5) In a file book in which a bag sheet having a sheet bag storage portion having an opening in an outer direction or an upper and lower edge direction with respect to a binding margin is bound, a pressure-sensitive adhesive is applied to the bottom or side edge of the bag storage portion. A bag file book for a sheet, provided with an adhesive edge obtained by fusing a bag film through a layer or a fusion preventing agent layer.

The present invention will be described in more detail with reference to the drawings of embodiments. As shown in FIG. 3 (plan view) and FIG. 4 (cross-sectional view), the bag sheets used in the bag file book of the embodiment of the present invention include the left and right back surfaces of the core sheet 1 and the bag films 2, 2 '.
There are a total of four sheet bag portions formed by the upper and lower fusing edges 4, 4 'and the folds 6, 6' of the bag films 2, 2 '. The bag portion for the sheet of the present invention is a bag-like shape in which two rectangular films or sheets are overlapped and three sides are closed and one is opened in a state where the sheets are superimposed, and a thin material such as paper 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 body sheet. The height of the upper and lower fused edges 4 and 4 'in FIG. A sheet having a width of the edges 8 and 8 '. The core sheet of the present invention is a sheet made of a thermoplastic plastic, and can be used for both a thin film and a thick sheet. Further, the core material sheet can be made opaque by coloring or the like.

In particular, when used for an album, the core sheet 1 becomes opaque behind the photographic paper placed on the opposite side of the bag.
Need not be opaque. The bag films 2 and 2 ′ are bent right and left of the core sheet 1 so as to wrap the core sheet side edges 8 and 8 ′. The bag opening edges 5, 5 'at the ends of the bag films 2, 2' extend up to the line AB to form the opening edges of the bag. The upper and lower fusing edges 4, 4 'of the bag films 2, 2' are the core material sheet 1 and the front and back bag films 2,
Three 2's are simultaneously fused. Bag film 2,
Reference numeral 2 'denotes a thin thermoplastic plastic film having a thickness of about 20 to 200 [mu] m, which needs to be transparent in order to view stored photographic 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 and the like can be suitably used. Between the bag opening edges 5, 5 'on both sides of the bag sheet, there is a fusion central portion where only one core material sheet 1 exists, and this portion can be fused and fixed to the cover sheet 11. .

In this embodiment, the roughened ink application surfaces 7, 7 'are applied near the opening edge of the bag film.
Writable. The bag sheet of the present invention is characterized in that a heat-sensitive adhesive layer or an anti-fusing agent layer 3, 3 'is provided on all or a part of the three edges of the bag body on the left, right, AC, CD and DB lines in FIG. There is a feature. The heat-sensitive adhesive layer or the anti-fusing agent layer 3, 3 'can be provided in a range of about 3 to 10 mm from the edge of the bag. In the case of the embodiment shown in FIG. 3, heat-sensitive adhesive layers or anti-fusing agent layers 3 and 3 'are provided at the edges of the left and right CDs. This is done by applying a heat-sensitive adhesive to positions corresponding to the left and right bag film folds 6 and 6 ′ of the bag films 2 and 2 ′, forming a bag sheet, and heat sealing from the outside of the fold. With the heat-sensitive adhesive layer, the bag film 2,
2 ′ and the end of the core material sheet 1 with a margin of about 1 to 3 mm from the inner end of the heat-sensitive adhesive coating layer, for example, 2 to 9 m from the end of the bag body
Adhere and fix with a width of m.

In this case, the heat sealing is desirably performed outside the inner lines 9 and 9 'of the heat-sensitive adhesive layer or the anti-fusing agent layer, and when the heat-sensitive adhesive layer adheres too strongly, it is stored in the bag. Therefore, it is desirable to adjust the heat-sealing temperature to a low value to reduce the adhesive strength. In addition, the heat-sensitive adhesive may be added with a material such as wax to reduce the adhesive strength, so that the adhesive strength suitable for the present invention can be obtained. The width of the heat-sensitive adhesive layer or the anti-fusing agent layer 3, 3 'is appropriately selected, but is usually applied in a width of about 3 to 10 mm, preferably about 5 to 10 mm. Thermal adhesives are polymers that adhere when melted and cooled by heat, for example, ethylene-vinyl acetate copolymers, polyamides,
A heat-sensitive adhesive such as polyester can be used.
Rosin, pinene-based resin, and the like can be added as a tackifier thereto. As another embodiment of the present invention, an anti-fusing agent can be applied instead of the heat-sensitive adhesive layer or the anti-fusing agent layer 3, 3 'of the previous embodiment. The anti-fusing agent has an effect 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 the heat sealing, the film at the heat sealing portion can be easily peeled off with a finger.

The anti-fusing agent can be used without any particular limitation as long as it has the above-mentioned action, but those which are dried after application, for example, printing ink, drying oil, wax and the like are desirable. When an anti-fusing agent is used, applying a normal amount to prevent anti-fusing will lower the adhesiveness.Therefore, apply the anti-fusing agent thinly, or heat it a little harder during heat sealing. It is desirable to bond them in a semi-molten state. Also in this case, the inside of the application edge of the anti-fusing agent is 1 to 3 m.
Desirably, heat sealing is performed for at least m. The pressure-sensitive adhesive layer or the anti-fusing agent layer of the present invention is provided along the edge of the bag body. The mode is not limited to FIG. 3, for example, as shown on the right side of FIG. A mode provided on all edges of CD and DB,
As shown in the left side of FIG. 5, there are a mode in which AC and DB are provided on the upper and lower edges, a mode in which it is provided in the upper and lower corners in the right side of FIG. .

According to the present invention, a plurality of bag sheets can be laminated and simultaneously fused on the cover sheet 11 to form a bag file book as shown in FIGS. If a thick plastic sheet is used for the cover sheet of the present invention, a plurality of bag sheets are placed on the cover sheet, and the center part is directly fused with an ultrasonic seal or a high frequency seal or another fusion method. In addition, the entire bag sheet and the cover sheet can be fused at once. As a fusion method, an ultrasonic seal is preferable from the viewpoint of fusion strength and finish appearance. 1 and 2 use thick paper for the cover sheet 11, and in this case, a thick fusion-bonded plastic sheet 12 is bonded to the center of the cover sheet 11 with an adhesive. A bag file book can be obtained by fusing the bag sheet laminate to the plastic sheet for fusion in the same manner as described above. It is preferable to use paper-made cover paper because it is stiff, has excellent structural functions as the cover, and can perform beautiful printing.

FIG. 1 shows an embodiment using the bag sheet of FIG. When photographic paper is to be put into the bag portion of the bag file book, for example, photographic paper having a size of half the width of the bag is inserted from the bag opening edge 5, and the tip of the photographic paper is a heat-sensitive adhesive layer or an anti-fusing agent. When the photographic paper is slightly pressed into the layer 3 when the photographic paper is pressed, the edge of the photographic paper is fixed into the heat-sensitive adhesive layer. Even if you repeat the page of the bag file in this state,
The photographic paper does not move at all in the bag, and is stored in the initial storage position. The bag sheet of the bag file book of the present invention is disclosed in Japanese Patent Publication No. 1-3679.
In the method described in No. 8, it can be produced by applying a heat-sensitive adhesive or an anti-fusing agent to a considerable portion of a bag film. In this production, since the heat-sensitive adhesive and the printing ink are dried after being applied, they can be applied to this production method without any trouble. In the bag file book of the present invention, in the case where the opening of the bag is located outward with respect to the binding margin, the inside of the bag film on both sides of the core sheet is heat-sealed as in the embodiment of FIG. There is a bag opening edge 5 in the outer direction with respect to the center binding margin G, and sheets can be inserted from the outside.

Also in this case, the same heat-sensitive adhesive layer or anti-fusing agent layer as described above can be provided on all or part of the bottom edge E or side edge F of the bag body in the same manner as in the above embodiment. The center binding margin G of the bag sheet can be fused to the cover sheet in the same manner as in the above embodiment to form a sheet bag file book. Similarly, in the embodiment of the present invention having an opening in the upper and lower edges with respect to the center binding margin G, as shown in FIG. 8, a heat-sensitive adhesive layer or a fusion adhesive is provided on the bottom edge E or the side edge F of the bag. An anti-adhesion agent layer can be similarly provided. The bag sheet of FIG. 8 is obtained by heat-sealing one film at the bending line H, and is the simplest bag sheet having one bag body per one bag sheet. This center binding margin G can be fused to form a sheet bag file book. The bag file sheet having the opening portion on the outer side or the upper and lower edges used for the bag file book of the present invention is made of plastic film and has a bag body portion, and any shape having a binding margin can be used. However, it is particularly desirable that the core material sheet has four bag portions on both left and right sides. FIG.
As described above, even a single page having one bag on each page can be used as appropriate in terms of easy production. In the case of the bag file book of these aspects, when storing the sheet, pressing the end of the sheet against the heat-sensitive adhesive layer or the anti-fusing agent layer and storing the sheet together with the pinching force of the bag film The position of the storage sheet can be held at the initial storage position.

[Effects of the Invention] The bag file book of the present invention stores, for example, sheets such as photographic paper, even if the sheets are smaller in size than the bag body, the sheets are stored first without displacement. It has the advantage that it can be stored as it is. In addition, there is an advantage that the effect of preserving the position is not reduced even if storage and take-out are repeated considerably to the extent that normal operation is performed. Because of this advantage, it is most suitable as a photo album or sample book, and its demand is many and useful.
