[0002]
[Prior art]
Conventionally, this type of file has a file body having a front cover portion and a back cover portion, or a front cover portion, a back cover portion, and a back cover portion, and a sheet material that is separated from the file main body. is there. As an example of this, for example, an opening window that penetrates the thickness of the file body is provided in the front cover portion, and the opening window is closed with a sheet material, and even when the file is closed, the file is opened through the opening window. A part of the peripheral edge of the sheet material that can be visually recognized from outside such as bound paper, the front or back cover part of the file body, the surface or inner surface of the back cover part, or the surface of the back cover part. A pocket portion is formed by adhering except for, and a document title bound in a file is displayed by inserting a name card or the like into the pocket portion. In such a file, a sheet material is usually bonded to the file body by means such as welding.
[0003]
[Problems to be solved by the invention]
In such a file, when the sheet material is bonded to the file main body, there are cases where continuous irregularities are formed in the bonded portion. This is the shape that occurs when the sheet material is bonded to the file body by welding, but this uneven shape realizes welding in a very narrow range, and also the appearance of the welding part and the welding strength It is formed by the welding technique adopted in order to also realize the goodness of. At that time, for example, when the sheet material is welded to the file main body by continuously pressing and heating at a predetermined pitch along the peripheral edge of the sheet material, the uneven shape is particularly prominent. However, if such unevenness occurs, for example, when the sheet material is bonded to the inner surface of the file body, the unevenness causes marks and scratches on the surface of the paper or paper holder bound in the file. there is a possibility. Regardless of whether the sheet material is provided on the front side of the file body or on the inner side, the file user may injure his / her finger if the convex and concave portions are sharp. it is conceivable that.
[0004]
In view of the above-described problems, the present invention has as its main object to provide a file having a high safety and a good appearance with respect to the user and sheets bound inside.
[0005]
[Means for Solving the Problems]
That is, the file of the present invention includes a front cover portion and a back cover portion that form a front / back pair, or a file main body having a back cover portion in addition thereto, and a front cover portion, a back cover portion, or a back cover portion of the file main body. A sheet material that is bonded to any surface or inner surface, and the sheet material is a file in which a protrusion is formed on the surface and bonded to the file body, and all or part of the peripheral edge of the sheet material A concave portion in which a part of the surface or inner surface of the corresponding file body is recessed is formed, and the top of the protrusion that appears on the anti-stick surface at the peripheral edge of the sheet material is substantially the same as the surface or inner surface of the corresponding file body. The sheet material is characterized in that the peripheral edge portion of the sheet material is positioned in the recess and adhered to the file body so as to be flush with the surface.
[0006]
In the case of a file having such a configuration, regardless of the bonding means, the protrusion generated when the sheet material is bonded to the file main body is substantially buried in the recess formed in the file main body. Therefore, when the sheet material is bonded to the inner surface side of the file body, it is possible to easily prevent the paper bound to the file and the paper holder generated by the protrusion from being damaged, and the sheet material is attached to the file body. When adhered to the front side, for example, when the file is stored on a shelf or the like, it is possible to prevent the surface of the article such as another file arranged adjacent to the file from being damaged. Furthermore, even if the sheet material is adhered to either the front surface side or the inner surface side of the file, it is possible to effectively prevent the user from being injured by hooking his / her finger on the protrusion.
[0007]
Usefulness by such a file is extremely effective when the peripheral edge of the sheet material is easily pressed with the file main body in the recess, and is welded by heating or the like. In addition to this, for example, ultrasonic welding is also included in the welding method.
[0008]
As an example of the arrangement mode of the sheet material with respect to the file body, an opening window that penetrates the thickness is formed in a part of the front cover part or a part of the back cover part, and the sheet material is arranged at a position to close the opening window. In addition, a concave portion is formed on the surface or inner surface of the front cover portion or the back cover portion corresponding to substantially the entire peripheral edge portion of the sheet material, and the substantially entire peripheral edge portion of the sheet material is adhered in the concave portion. . In this case, in order to improve the appearance of the file and effectively prevent damage to the internal paper or the like, the sheet material may be bonded to the inner surface side of the front cover portion or the back cover portion.
[0009]
As an example of another arrangement mode for the file main body of the sheet material, a non-adhesive portion that is not bonded to the file main body is provided in a part of the peripheral edge of the sheet material, and the sheet material and the portion of the file main body to which the sheet material is bonded, What formed the pocket part which can insert the other member which makes | forms a sheet form between the non-adhesion part and the surface or inner surface of a file main body is mentioned.
[0010]
In the above file, a concave portion is formed on the surface or the inner surface of the file body. To prevent the concave portion from appearing on the surface opposite to the surface on which the concave portion is formed, the file main body is foamed. It is preferable to form from a resin material. On the other hand, in order to make the original functions of the opening window and the pocket portion useful, it is preferable to form the sheet material from a transparent or translucent resin film.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0012]
A file 1 according to the present embodiment shown in FIG. 1 is configured to be able to bind a sheet or the like (not shown) inside, and is mainly composed of a resin file main body 2. The file main body 2 includes two types of files 1. The sheet materials 3 and 4 are bonded, and a binding tool 5 for binding sheets and the like is further provided.
[0013]
First, as shown in FIGS. 1 and 2, the file main body 2 has a size corresponding to, for example, A4 standard paper or the like, both of which are a front cover portion 21 and a back cover portion 22 each having a substantially rectangular plate shape. In addition, the spine cover 23 having a rectangular plate shape with a width corresponding to a predetermined number of sheets is integrally provided. The file main body 2 is an integrally molded product of foamed resin material, and the boundary portion that divides the front cover portion 21 and the back cover portion 23 and the back cover portion 22 and the back cover portion 23 is slightly thinned and bent at that portion. Possible hinge portions 2a, 2b are formed. Further, the front cover portion 21 has an outermost surface such as a sheet bound to the inner surface side of the back cover portion 22 or the binding tool 5 in a state where the file 1 with the front cover portion 21 and the back cover portion 22 facing each other is closed. Is formed by penetrating in the thickness direction an opening window 24 having a substantially rectangular shape. The opening window 24 is closed by a first sheet material 3 to be described later. In addition, around the periphery of the opening window 24 on the inner surface 21b of the front cover portion 21, the shape and size of the first sheet material 3 are accommodated as shown in FIGS. Thus, a concave portion 25 having a substantially rectangular shape that is slightly larger than the opening window 24 is formed. FIG. 6 is a schematic perspective view showing the vicinity of the recess 25 in an enlarged manner. The concave portion 25 is formed by partially denting the inner surface 21b by applying a predetermined pressure to the inner surface 21b of the front cover portion 21 during molding. As a result, the surface 21a side is not reached. Further, as shown in FIGS. 1, 3 and 4, a pocket portion 26 is formed on the surface 23a of the spine portion 23 by attaching a second sheet material 4 to be described later. A name card or the like (not shown) in which a title of a document made of paper or the like bound on the inside of the file main body 2 is described can be stored in the file 26. Then, a concave portion 27 having a vertically long U shape corresponding to the shape and size of the second sheet material 4 is formed on the surface 23 a of the spine cover portion 23. Similarly to the concave portion 25, the concave portion 27 has a concave depth of, for example, approximately half of the thickness of the spine portion 23 so as not to reach the back surface 23b side. In addition, the concave portion 27 is not formed in the portion corresponding to the upper edge portion 41a of the second sheet material 4 because the name card or the like is not attached to this portion without bonding the second sheet material 4. This is because the pocket portion 26 is taken in and out.
[0014]
As described above, the first sheet material 3 is made of a resin transparent film having a substantially rectangular shape that is slightly larger than the opening window 24. And the whole area of the peripheral part 31 is located in the recessed part 25 around the opening window 24 as shown in FIG. 5A, a predetermined pressure is applied from the first sheet material 3 side, and further heating is performed. It is welded to the front cover portion 21 in the recess 25. At this time, a large number of protrusions 32 projecting continuously toward the anti-adhesion surface 3a side of the first sheet material 3 at a predetermined pitch along the peripheral edge portion 31 of the first sheet material 3 by pressurization and heating. The welding method is used. Then, as shown in FIG. 5B, the height of the projection 32 is substantially the same as the depth of the recess 25, and the top 32a of the projection 32 is substantially flush with the inner surface 21a of the cover portion 21. Further, the entire protrusion 32 is buried in the recess 25.
[0015]
The second sheet material 4 is also made of a resin transparent film similar to the first sheet material 3 and has a vertically long, roughly rectangular shape corresponding to the shape of the spine cover portion 23. And the lower edge part 41b except the upper edge part 41a and the both-sides edge part 41c in the peripheral part of this 2nd sheet | seat material 4 are positioned in the recessed part 27 formed in the spine cover part 23, and it welds in this recessed part 27 Yes. This welding method is the same as the welding method for the concave portion 25 of the first sheet material 3. Therefore, the same protrusion 42 as the peripheral part 31 of the 1st sheet material 3 is continuously formed in the anti-adhesion surface 4a side also in the lower edge part 41b and the both-sides edge part 41c of the 2nd sheet material 4. The protrusion 42 is buried in the recess 27 so that the top 42 a of the protrusion 42 is substantially flush with the surface 23 a of the spine cover 23. Note that the notch 41d having a substantially semicircular shape is formed in the upper edge 41a at the peripheral edge of the second sheet material 4 because the name card or the like for the pocket 26 is formed through the notch 41d. This is to facilitate loading and unloading.
[0016]
In the present embodiment, the binding tool 5 fixes a base portion 51 arranged on the inner surface side of the spine cover portion 23 to the spine cover portion 23 using a plurality of rivets 53, and operates a plurality of rings 52 on the base portion 51. Since it is a general ring-type binding tool 5 that can be opened and closed by operating the unit 54, detailed description thereof is omitted. In addition to the configuration described above, various types of binding tools can be used as long as they have a function of binding sheets and the like.
[0017]
In the file 1 of the present embodiment configured as described above, the sheet materials 3 and 4 are attached to the front cover portion 21 and the back cover portion 23 of the file body 2, respectively. Concave portions 25 and 27 are formed at locations where the portions 31, 41 b and 41 c are positioned, and the sheet materials 3 and 4 are bonded to the file body 2 by welding in the concave portions 25 and 27. And the top part 32a, 42a of the protrusions 32 and 42 formed in the peripheral part 31, 41b, 41c of the sheet | seat materials 3 and 4 at the time of the welding is the inner surface 21a of the cover part 21, and the surface 23a of the spine part 23. Therefore, the protrusions do not protrude from the inner surface 21a and the surface 23a. Therefore, particularly on the inner surface 21a side of the front cover portion 21, the projection 32 of the first sheet material 3 formed by welding damages the surface of the paper, paper holder, or the like bound inside the file body 2. Can be effectively prevented. In addition, since both the protrusions 32 of the first sheet material 3 and the second sheet material 4 are substantially flush within the recesses 25 and 27, the user places a finger on the protrusions 25 and 27. It is possible to prevent the self who gets caught and injured.
[0018]
Further, since the file main body 2 is a foamed resin molded product, the surface on the side opposite to where the traces of the concave portions 25 and 27 are formed, that is, the surface 21a of the cover portion 21 and the inner surface of the spine portion 23. Since it is difficult to express in 23b, the appearance of the file 1 can be kept extremely good.
[0019]
Further, the first sheet material 3 closes the opening window 24 formed in the front cover portion 21, and the second sheet material 4 constitutes a pocket portion 26 formed in the spine portion 23. Since each of the sheet materials 3 and 4 is formed of a transparent resin film, the inside of the file body 2 closed through the opening window 24 can be seen from the outside, or the interior of the pocket portion 26 can be seen. The original function of the window part 24 and the pocket part 26, which makes the name card inserted into the window visible from the outside, can be made effective.
[0020]
In addition, this invention is not restricted to embodiment mentioned above, The aspect which adhere | attaches a sheet | seat material by making a file main body into paper can also be employ | adopted, and does not form a protrusion intermittently as mentioned above. Alternatively, it may be formed continuously in a straight line or a curved line. In addition, various modifications can be made to the specific configuration of each part, such as the size and configuration of each part of the file body, the presence or absence or position of the window part or pocket part, the number of sheets, and the location of the sheet material without departing from the spirit of the present invention. Is possible.
[0021]
【The invention's effect】
As described in detail above, the file of the present invention can be used for various purposes such as for closing an opening window formed in the file body or for forming a pocket portion for inserting a name card on the surface or inner surface of the file body. When bonding the sheet material forming the body, the surface or part of the inner surface is recessed to form a recess at a location corresponding to all or part of the peripheral edge of the sheet material to be bonded to the file body. By adhering the peripheral edge of the sheet material in the recess, the top of the protrusion formed on the sheet at the bonding location is substantially flush with or lower than the surface or inner surface of the file body. It is composed.
