BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an album book in which a large number of plastic bags are bound into a book form.

[0002]

2. Description of the Related Art Conventionally, a bag file book made of sheets has an opening in an upward direction with respect to a binding margin, an opening in an outward direction, and a horizontal insertion opening in a central binding direction. Although it is considered that there is some, a bag file of a horizontal insertion type having an opening in the central direction is said to be more convenient in that there is no risk of the contents falling when the file book is bound. As such a bag file, according to Japanese Utility Model Laid-Open No. 59-53981, Japanese Patent Publication No. 1-36798 and Japanese Patent Laid-Open No. 61-297194, a bag film is covered in a U-shape on both wings of a core film. It is known that a bag body is formed on both sides of the wings of the core film by fusing three sheets of the core film and the bag film at the upper and lower edges. Recently, such a bag file book has come to be used as an album book. But,
If the size of the photo is smaller than the size of the bag, the inserted photo is easy to move in the bag and the photo is bent when the album is opened and viewed. In particular, recently, panorama size and normal size photos can be freely selected and taken, so when the size of the bag body of the album bag sheet is adopted according to the panorama size, the normal size photo is Although two pieces fit in the bag, they move inside the bag and the two pieces overlap or become slanted, which is not good as an album. To prevent this, you can put an adhesive on the back of the photographic printing paper and attach it to the core film, but in this case, the operation of replacing the pictures becomes complicated and the replacement of the stored pictures is easy. You lose the biggest advantage of the bag file.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an album book in which a photographic sheet is not displaced in a bag body.

[0004]

The present inventor has found that the sheets stored in the bag body of the bag file book of the above-mentioned known shape are sandwiched between two bag body films. Paying attention to the fact that the stored thick sheets will not slip or fall inside the bag as long as the edges of the sheet are fixed with a weak force. We succeeded in stabilizing the position of the stored items by forming it in the part. That is, the bag body film and the core material film are close to each other near the bottom edge of the bag body portion of the bag file book having the above-mentioned known shape, but they are in a state of being freely movable without being bonded. In such a state, there is no force to fix the photo at the edge, so first, the core film and the bag film are heat-sealed at the edge of the bag bottom, and the core film at the bag bottom edge is first fused. I narrowed the gap between the bag and the film and tried to fix the photo with the tightening force when I pushed the photo into this gap. However, even in this case, the prevention of the misalignment of the stored photographs was not sufficient. It is understood that this is because the core material film and the bag film are soft and the tightening force of the gap is weak. By fusing the bag film and the core film at the same time with the film sandwiched therebetween, it was possible to increase the tightening force when the photograph was pushed into the bottom edge.

That is, the present invention comprises the following items. (1) As a three-layer structure in which a bag film is arranged on the left and right sides in a U-shaped cross-sectional structure with an area of a space parallel to the central part of the core material film, the upper and lower edges of the three-layer structure The bag body portion formed by fusing the core material film and the bag film with the core material film and the bag film, the bag body portion having an opening toward the center is A plastic in which a plurality of bag sheets each having at least four bag body portions on the left and right sides of the film and on the right and left sides thereof are stacked and laminated on a cover sheet, and the central portion of the laminated bag sheet is fixed to a thick cover sheet by fusion bonding. In an album book made by a manufacturer, a thick plastic tape is laminated on at least one surface of the core material film along the side edge of the core sheet and the bottom edge of the bag, and the side edge of the thick plastic tape is sandwiched. The side edge of the core film and the bag Album book, characterized in that fused fixed simultaneously with the side edges of Lum. (2) The album book according to item 1, wherein the cover has a plastic sheet adhered to the central portion of a paper sheet.

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 for the album book of the embodiment of the present invention is
A bag for a sheet formed by the right and left back surfaces of the core material film 1, the bag films 2 and 2 ', the upper and lower fusion edges 4 and 4', and the fold fusion edges 6 and 6'of the bag films 2 and 2 '. There are four body parts in total. The core material film 1 is shown in FIGS.
As shown in FIG. 3, the core of the bag body sheet is configured, and the left and right bag body parts are connected and the inner wall surface of the bag body is formed. Further, the central portion of the core material film serves as a binding margin when the bag sheet is fused and fixed to the cover sheet. Its dimensions are a film or sheet having the height of the upper and lower edges 4 and 4'and the width of the left and right 8 and 8'in FIG. The core film of the present invention is a thermoplastic plastic sheet, and can be used with a thin film or a slightly thick sheet. Further, the core material film can be made opaque by coloring or the like.

The bag films 2 and 2'are bent to the left and right of the core material film 1 so as to wrap the ends 8 and 8'of the core material film 1. Edges 5 and 5'of the bag film 2 and 2 '
Extends to the line AB and serves as an opening edge of the bag. On the lower edges 4 and 4'of the upper edges of the bag films 2 and 2 ', three core film 1 and three bag films 2 and 2'of the front and back are fused at the same time. Further, in the above-mentioned known bag file, the bag files 2 and 2'are only bent in a U shape so as to wrap the end of the core material file on the left and right side edges of the bag,
In the bag sheet of this embodiment, the side edge fusion-bonding portions 6 are fusion-bonded and fixed. At the time of this fusion, the thick and thick plastic tapes 3 and 3'are simultaneously fused to the side edge fusion portions. As a result, at the bottom edge of the bag body, the core material film 1,
Two bag films 2 and 2'and a plastic tape 3 are integrally fused. Plastic tape 3
Can be provided on both sides of the core material film, and in this case, the fixing force of the photograph is further increased, which is desirable.

This fusion is performed by using a conventional heat roller or ultrasonic wave.
It can be performed by heat sealing with high frequency or the like. Further, instead of this heat sealing, it is also possible to continuously fuse and cut the bottom of the bag body portion to provide the side edge fusion portions 6 and 6 ′. Further, the heat-sensitive adhesive applied in advance allows the thick plastic sheet and the bag film to be fused to the side edges of the core film by heat. The bag sheet used for the album of the present invention is
In the method of manufacturing a bag sheet according to each of the above-mentioned publicly known publications, instead of the core material film to be used, by using the core material sheet 1 having thick tapes fused at both ends as shown in the sectional structure of FIG. A bag sheet is manufactured by the same method as the above, and then the left and right side edges of the bag sheet are heat-sealed or melt-fused to the left and right side edges of the core material film 1, the plastic tape 3, the bag films 2, 2 It can be manufactured by fusion fixing. In this case, if the inner tapes 10 and 10 'of the plastic tape are fused to the core film as shown in FIG. 5, the plastic tapes 3 and 3'of FIG. Inside 9,
Since the line 9'is in close contact, it is convenient because the photograph does not enter between the plastic tape and the core material film and is not hidden behind the plastic tape 3.

Further, in the present invention, a thick plastic tape 3 may be provided on both front and back surfaces of the core material film. The core film and the bag films 2 and 2'have a thickness of 20.
It is a thin thermoplastic film with a thickness of about 200 μm, and the bag film needs to be colorless and 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 degree of strength, and polyethylene, polypropylene, polyester, nylon and the like 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, in which only one core material film 1 is present, and this portion may be fused and fixed to the cover sheet. it can. The center part of the bag sheet is only the core material film, and since many core material films are laminated and fused at the same time, if the core material film is too thick, the number of fusion materials will decrease, so the core material film allows strength. As far as possible, it is desirable to make it as thin as possible. The second feature of the present invention is that a thick plastic tape is used only on the bottom edge of the bag which requires a strong waist, and the central portion is a thin film convenient for heat fusion.

In this embodiment, the roughened ink layers 7 and 7'are applied near the opening edge of the bag film so that writing is possible. The bag sheet of the present invention is A on the left and right of FIG.
CD among the three edges of fusion of the bag on C, CD and DB lines
It is characterized in that the plastic tape 3 is fused at the same time to the bottom edge fusion portion 6 of FIG. Thick plastic tape 3
Usually, it can be provided within a range of about 3 to 30 mm from the bottom edge, and depending on the case, it can be laminated to fill the inner surface of the bag body or leave a binding margin for fusion at the center. 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 an album 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 may be placed on the cover sheet and the central portion may be directly fused by ultrasonic sealing or high frequency sealing or other fusing method. ,
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 as the cover sheet 11, and in this case, the thick thermoplastic sheet 12 is bonded to the central portion of the paper sheet 11 with an adhesive. An album book can be obtained by fusing the bag sheet laminate to this plastic sheet in the same manner as above. It is preferable to use a paper cover as an album because it is more flexible, the structural function of the cover is excellent, and beautiful printing is possible. FIG. 1 shows an embodiment using the bag sheet of FIG. When inserting photographic paper into the bag body of this album book, for example, insert the photographic paper having a size half the width of the bag body from the opening edge 5, and when the tip reaches the bottom, press the photographic paper a little strongly. When pushed in, the edges of the photographic printing paper bite into place and are fixed. At this time, since the plastic tape is strong, the force of pressing the edge of the pressed photo acts to prevent the photo from being displaced. Although the force of pressing this edge is weak, the bag film also acts to press and hold the photo, so even if the page of the album is flipped, the above-mentioned photographic paper can be pressed with such a weak force. The is stored in the original storage position without any movement within the bag.

[0012]

[Effect of the Invention] For example, when the photographic printing paper is stored in the album book of the present invention, even if the photograph has a size smaller than the bag body, the position of the photograph does not shift and the original storage state is maintained. It has the advantage that it can be stored. Further, there is an advantage that the effect of position preservation is not deteriorated even if the storing and taking out are repeated to the extent that they are normally performed.
