2. Description of the Related Art Conventionally, a file book in which a plastic bag is bound has been widely used. In this case, since the bag sheet is made of a thermoplastic plastic film, the cover is also made of a thermoplastic plastic sheet, so that when binding the bag sheet, the central portion of the bag sheet can be fused and fixed together with the cover sheet, and the file book can be easily created. The advantage of being able to manufacture is preferred. However, since the conventional bag file book is made of plastic film, it is inconvenient to write a list of contents and a description article. For this reason, a small sample, a design,
When a large number of color samples, business cards, magnetic cards, credit cards, etc. are filed, it is necessary to take out the actual thing from the bag or the materials etc. put in the bag at the same time and check the stored items, which is troublesome to search. was there.

[0003]

According to the present invention, it is possible to maintain the easiness of manufacturing that the center of the bag sheet can be fusion-fixed by fusing, and to easily describe the contents. It is an object of the present invention to provide a bag file book which can be easily grasped by writing on a writing surface and can be easily taken out.

[0004]

Means for Solving the Problems The present inventor uses a conventional plastic film bag sheet file by using a writable plastic film sheet on one page and a bag body portion on the other page. A bag file book with writeability that can be manufactured by the same simple manufacturing method has been completed.

That is, the present invention is a bag file book in which the central portions of a plurality of plastic film bag sheets are integrally fused and fixed to the central portion of the inner surface of one top sheet. The plastic film bag sheet is obtained by polymerizing a film on both sides of one page of a core material sheet, and fusing and fixing the core material sheet and the two polymerized films at an upper edge and a lower edge of the page. A bag body portion having an opening is formed on the front and back of one page, and the other page has a writable surface formed by applying a roughening ink to both surfaces of a core material sheet on the front and back. The page having the bag portion and the page having the writable surface are alternately reversed and stacked such that the page having the writable surface is placed on the page having the bag portion and the page having the bag portion is written. The possible surfaces were alternated It is to provide a bag file book and features.

FIG. 1 is a cross-sectional view of an embodiment of the present invention. For simplicity, a case where two bag sheets 4 are directly fused and fixed to a top sheet is shown. In the file, a large number of bag sheets 4 are stacked on top of each other, and the respective bag sheets are fused and fixed.
It becomes a file book of the laminate. The bag sheet 4 used in the present invention is formed of a plastic film. The material is not particularly limited as long as it is a thermoplastic plastic film, but a polypropylene film is most desirable in terms of strength and transparency. The bag sheet used in the present invention has a laminated structure of a core material sheet and a bag film, and includes a page having a bag on one of the left and right pages and a page having a writing surface on the other, with the center being a binding margin, and a single-sided page. The provided bag body portion is formed by fusing films laminated on both sides of the core material sheet at the upper edge and the lower edge of the core material sheet and providing an opening in the lateral direction. It is preferable that the bag is a horizontally inserted bag having an opening toward the central binding margin of the file, since stored items do not fall. If desired, a bag sheet, such as a horizontal insertion type, having an opening on the outside can be used.

The basic shape of the bag sheet 4 used in the present invention is as follows.
As shown in the embodiment of FIG. 4, there is a thermoplastic core sheet B, and a bag body film A integrally connected at the right end to both the front and back surfaces of the right page except for the central part of the sheet.
As shown in FIG. 5, the upper and lower edges of the three laminated films on the right page are fusion-fixed (upper and lower edge fusion-fixing portions D), and the edges of the laminated film are formed into openings G as shown in FIG. It is what it was. The right fold that hits the bottom of the bag is the bag film A
Are continuous, and the front and rear bag portions are separated by a core sheet. Each of the front and back sides of one page of the bag sheet of this embodiment has at least one or more bag portions. Since the roughening ink is applied to the core material sheet roughening ink application surfaces E and F on the other left page, writing can be performed with a writing implement such as a pencil or a ballpoint pen. As the roughening ink, for example, a mat ink or the like obtained by mixing an inorganic powder such as silica with the ink can be used.

In a page having a bag portion, two or more storage portions can be formed on one side by dividing the bag portion horizontally by a horizontal heat seal. Also, lines and characters such as ruled lines and numbers can be printed on the writing surface coated with the roughening ink. If desired, as shown in FIG. 5, a heading piece M can be integrally extended from the end of the bag sheet at the end of the bag sheet. I can put it. This heading piece can be easily formed only by using a fusing blade having a partially convex shape in the fusing step of forming the upper edge or the lower edge. When a bag film book is created using the bag sheet of FIG. 4, there is no particular limitation on the lamination mode. For example, the bag sheet of FIG. When the left and right sides of the sheet are alternately reversed and laminated at the center, a bag file book in which a page having a bag portion and a writing surface are alternately combined can be obtained.

The bag sheet of this embodiment is fused and fixed on the cover sheet at the center binding margin C of the sheet. The cover sheet used in the present invention may be a thick plastic sheet or a paper sheet. When a paper sheet is used, the cover is stiff, so it is convenient to set up a file book for storage and handling.However, in order to fuse and fix the bag sheet to the cover, a thermoplastic resin is added to the paper cover sheet. It is desirable that a film, preferably a resin film of the same quality as the bag sheet core material, is laminated on a paper sheet and the film and the bag sheet are fused. There are three embodiments of the fusion method of the present invention.
The first mode is a mode in which a plastic film is laminated on the entire back surface of the paper-made topsheet itself, and the bag sheet is fused and fixed to the laminated plastic film.

As shown in FIG. 1, a second mode of fusing a paper cover sheet is that a laminated sheet piece of a paper sheet different from the top sheet and a plastic film is provided at the center of the inner surface of the top sheet made of paper. FIG. 2) is attached with an adhesive first between paper and paper, with the paper surface of the laminated sheet piece facing the topsheet, and then a plastic bag sheet is attached to the plastic film surface of the laminated sheet piece. This is an embodiment in which the fixing is performed by fusion. In the third mode of fusion, a plastic film sheet is adhered to the central portion of the top sheet, instead of the composite laminate sheet of paper and plastic sheet of the second mode, and the plastic bag sheet is fused thereto. It is a mode of wearing. The fusion fixing of the bag sheet of the present invention can be performed by an ultrasonic seal, a heat seal, a high frequency seal, or the like, but the ultrasonic seal is preferable in the present invention. In the fusing step of the present invention, the fusing and fixing of the top sheet and the first pouch sheet and the fusing and fixing of a plurality of pouch sheets are performed on the paper surface sheet in the same manner as the conventional plastic bag file book. Can be carried out in one step.

The top sheet made of paper is provided with fold lines 2 on the left and right sides of a central binding margin, and is bent inward by the fold lines 2. Because the cover is made of paper like this,
Such a fold line 2 can be provided. This fold line can be formed by a known creasing method used for a paper sheet, for example, a method such as embossing. Due to the fold line 2, the bag file book of the present invention becomes an angular shape when it is made to stand on its own. Can be stored, and the appearance when stored on a bookshelf is improved. Another advantage is that characters and the like can be freely and directly written on the outside of the binding margin of the paper cover and on the cover. As shown in FIG. 3, in the fusion fixing according to the present embodiment, all bag sheets can be fixed at the same time by ultrasonic fusion at a fixed width.

[0012]

[Effect of the Invention] The bag file book of the present invention has an advantage that the writing surface is blended in the bag sheet, so that the stored contents can be grasped by the description of the writing surface without being taken out of the bag and can be easily searched. .
