Description

The present invention relates to a document holder capable of accommodating and storing paper sheets and a file provided with the document holder.

Conventionally, a document holder that is mainly composed of a sheet-like material such as a synthetic resin sheet and is configured to accommodate paper leaves between the front cover and the back cover is well known. Such document holders include so-called pockets or clear holders, which are made of transparent synthetic resin sheets that allow the contents written on paper leaves to be visually recognized from the outside, and cover bodies. (For example, see Patent Document 1).

A document holder whose two consecutive sides are open or substantially open as described in Patent Document 1 makes it easy to put in and take out paper leaves, but the paper leaves contained in it suddenly move outward. It is possible that they will fall out.

Then, in the document holder described in the same document, as shown in FIG. 4, a protruding portion is provided so as to protrude from any of the two open sides of the front and back sheets, and the sheet is folded back to the other side. This makes it possible to prevent the paper leaves from coming off from the location.

JP-A-2009-29100

However, in the document holder described in Patent Document 1, it is conceivable that the document holder may be pulled out from one side that is still open, or that the bending of the protruding portion may be extended. Here, in order to more effectively prevent the paper leaves from being pulled out, it is conceivable to provide a plurality of protrusions disclosed in FIG. 4 of the same document or to make the structure and shape so that the bending is difficult to extend. In that case, the work of putting in and taking out the paper leaves into and out of the document holder becomes very complicated.

That is, at present, there is a document holder that can effectively suppress the removal of paper leaves, and can realize a state in which the removal of paper leaves can be suppressed and a state in which paper leaves can be easily taken in and out by a simple operation. It has been demanded.

The present invention has been made by paying attention to the above-mentioned points, and provides a document holder capable of reliably protecting paper leaves while improving the handling of paper leaves.

That is, the document holder according to the present invention is configured such that a back side sheet that supports paper sheets from the back side and two continuous sides with respect to the back side sheet can be brought into contact with each other so that the other sides are connected to each other. Attached to the front side sheet arranged so that paper leaves can be inserted and removed between the back side sheet, and the back side sheet and the back side sheet in the vicinity of a corner where two sides where the front side sheet can be brought into contact with each other are continuous. A sheet-shaped stopper body that can insert and hold the corner portion of the front side sheet between the back side sheet and the insertion side edge portion of the stopper body into which the corner portion of the front side sheet is inserted is inserted from the back side sheet. It is provided with a stopper having an expansion portion formed in the vicinity of the edge portion on the insertion side so as to be separated, and the expansion portion is formed between attachment points of the stopper body to the back side sheet. will do.

In such a case, since the stopper is provided on the back side sheet and the front side sheet over the two open sides, it is possible to effectively prevent the paper leaves inserted between the stopper and the back cover from being pulled out. Not only that, the front cover and the paper sheets can be easily inserted between the back cover and the stopper body by the expansion portion provided on the stopper. As a result, according to the present invention, it is possible to provide a document holder capable of improving the handling of paper sheets and reliably protecting the paper sheets.

In order to realize the stopper with a simpler configuration, it is desirable that the expanded portion is a valley fold line formed in the stopper body in the front view.

In order to more effectively promote the deformation of the stopper body due to the valley fold line, it is preferable to position the edge portion of the valley fold line at a position away from the mounting position of the stopper body with respect to the back sheet.

The document holder has a rectangular shape when viewed from the front, and in order to accommodate more and more sheets of paper having a predetermined shape, the back side sheet and the front side sheet can be brought into contact with each other on two consecutive sides. The first corner opening portion provided with the stopper and the back side sheet separated from each other at the first corner portion which is the corner corner, and the front side sheet and the front side sheet at the second corner portion which is the corner facing the first corner portion. It is desirable to provide a second corner opening portion provided with the back side sheet separated. As a result, it is possible to prevent the corners of the rectangular paper leaves from being unnecessarily stretched in the document holder, so that more paper leaves can be smoothly stored.

Then, in order to enable smoother insertion of the front side sheet and paper sheets into the stopper, one side to which the back side sheet and the front side sheet are connected is bound together with the other sheet. Assuming that the edge portion on the side is formed, the binding base side may be bound to be in a stable state.

Here, the other sheet includes not only other document holders having the same shape but also other types of document holders and files having different functions, or paper sheets.

Then, in order to realize a file in which the above-mentioned document holder can suitably accommodate paper sheets, the edge portion on the binding base side is provided with an attached portion for being attached to a cover body having a front cover and a back cover. It is desirable to make it.

At the same time, in order to enable the above-mentioned document holder to be suitably used as an element of a file or as a document holder alone, the edges on the binding base side are pierced at predetermined intervals. It is desirable to have multiple binding holes for binding the leaves.

In order to make the paper leaves highly readable, it is preferable that the front side sheet and the back side sheet are made of a transparent resin sheet material.

The file according to the present invention is characterized by including the above-mentioned document holder and a cover body having a front cover, a back cover, and a binding portion for binding the document holder between the front cover and the back cover.

If this is the case, the document holder bound to the binding part is engaged with the cover body, etc. on the binding base side, so friction between the cover body and the desk, etc. on which it is placed, or paper leaves, etc. Due to the weight of the stored file itself, it is possible to insert paper sheets between the front side sheet and the back side sheet in a stable manner without the back side sheet moving unnecessarily, as compared with handling the document holder alone. And, of course, the paper sheets and the front side sheet can be inserted between the stopper and the back side sheet in a state where the back side sheet is stably placed.

Since the present invention has the configuration described above, it is possible to provide a document holder capable of ensuring good handling of paper leaves and reliably protecting the paper leaves.

As a result, the front side sheet 3 arranged so that the document P can be inserted and removed from the back side sheet 2, the back side sheet 2 which can be detached, and the two sides where the front side sheet 3 can be detached are continuous. A sheet-like stopper main body 51 that is attached to the back side sheet 2 in the vicinity of the corner and can insert and hold the corner portion of the front side sheet 3 between the back side sheet 2 and the corner portion of the front side sheet 3 in the stopper body 51 is inserted. It is characterized by including a stopper 5 having an expansion portion 53 formed in the vicinity of the edge portion 5a on the insertion side so as to separate the edge portion 5a on the insertion side from the back sheet 2.

Hereinafter, a specific configuration of the document holder 1 according to the present embodiment will be described.

The document holder 1 is mainly composed of a back side sheet 2 and a front side sheet 3 formed by appropriately bending and welding a flexible and transparent sheet material. Specifically, the document holder 1 has a substantially rectangular shape in which the back side sheet 2 and the front side sheet 3 are joined to each other so as to open two continuous sides. In the present embodiment, the material forming the back side sheet 2 and the front side sheet 3 is a resin sheet material such as polypropylene, but of course, another resin material such as polyethylene or polyethylene terephthalate may be used. Further, the back side sheet 2 may be made of a material different from that of the front side sheet 3.

The document holder 1 has an open upper edge 1a in which the back side sheet 2 and the front side sheet 3 can be brought into contact with each other over the entire area on the upper end side in order to open two continuous sides and join the other two sides. The bottom edge 1b formed by folding back the resin material at the end facing the open upper edge 1a, and the binding base side joined by welding one side end of the open upper edge 1a and the bottom edge 1b in a band shape. It has a welded side edge 1c which is an edge portion of the above, and an open side edge 1d which is formed so that the back side sheet 2 and the front side sheet 3 can be brought into contact with each other over substantially the entire area at the end portion facing the welded side edge 1c. There is.

That is, in the present embodiment, the welding base side edge 1c corresponding to any one side to which the back side sheet 2 and the front side sheet 3 are connected is bound together with another sheet, that is, a plurality of other document holders 1. It constitutes a part. In addition, in the present embodiment, the welding side edge 1c has an attached portion 1f that can be welded because it is bound to the binding portion H4 of the file F described above.

In addition, the document holder 1 according to the present embodiment further has a stopper 5 capable of sandwiching the front side sheet 3 and the document P on the back side sheet 2. Then, by providing the stopper 5, the document holder 1 separates the stopper 5 and the back sheet 2 at the first corner portion where the back side sheet 2 and the front side sheet 3 can be brought into contact with each other at the corners where the two sides are continuous. A first corner opening portion 11 is further formed, and a second corner opening portion 12 provided with the front side sheet 3 and the back side sheet 2 separated from each other in the second corner portion facing the first corner portion is further formed. The specific configuration of the stopper 5 will be described later.

The back side sheet 2 has a rectangular shape to support the document P from the back side, and the document P, that is, the document support surface 21 for supporting the document P is provided over substantially the entire surface of the side facing the front side sheet 3. Have. Further, in the present embodiment, the back side sheet 2 has a stopper mounting portion 22 for mounting the above-mentioned stopper 5 in a region facing the open upper edge 1a and the open side edge 1d.

The front side sheet 3 has a substantially rectangular shape corresponding to the outer shape of the back side sheet 2, and has a transparent surface 30 having a transparent surface and a resin material in front of the open upper edge 1a and the open side edge 1d. It has a retracted edge 32 formed by slightly recessing the view, and a recess 33 formed by recessing the resin material in a substantially triangular shape in the vicinity of the welding side edge 1c in the open upper edge 1a. In the present embodiment, as shown in FIGS. 2 and 3, the retracting edge 32 is formed so that the stopper mounting portion 22 and a part of the stopper 5 of the back side sheet 2 are exposed to the front side. Further, the formation of the recess 33 promotes flexible deformation of the front side sheet 3 in the vicinity of the welded side edge 1s on the front side sheet 3, and for the user, the back side sheet 2 and the front side sheet 3 are separated from each other in the thickness direction. It is easy to insert fingers between the back side sheet 2 and the front side sheet 3. In the present embodiment, the front side sheet 3 has a predetermined area 34 at a position where two sides are continuous, that is, near a corner, such as an open upper edge 1a and an open side edge 1d.

Here, in the present embodiment, as shown in FIGS. 5 to 7, in addition to the back side sheet 2 and the front side sheet 3, the document holder 1 has two continuous sides on which the back side sheet 2 and the front side sheet 3 can be brought into contact with each other. A sheet-shaped stopper main body 51 that is attached to the back side sheet 2 in the vicinity of the corner and can insert and hold the corner portion of the front side sheet 3 between the back side sheet 2 and the corner portion of the front side sheet 3 in the stopper body 51 is inserted. It is characterized by including a stopper 5 having an expansion portion 53 formed in the vicinity of the insertion side edge portion 5a so as to separate the insertion side edge portion 5a from the back side sheet 2. Hereinafter, the configuration of the stopper 5 will be described.

The stopper 5 is made of a sheet-like resin material that is formed separately from the resin material that constitutes the front side sheet 3 and the back side sheet 2. Specifically, the stopper 5 functions so as to prevent the front side sheet 3 and the document P from being displaced from the back side sheet 2. This stopper 5 is attached to the back side sheet 2 in the present embodiment, and by inserting the front side sheet 3 between the cover and the back side sheet 2 from the insertion side edge portion 5a, the front side sheet 3 and the document P It is possible to prevent the back side sheet 2 from being displaced.

Specifically, the stopper 5 is different from the stopper main body 51 having a front view trap shape and the back side welded portion 52 which is a mounting portion welded to the back side sheet 2 at a portion corresponding to the inclined side of the stopper main body 51. The stopper main body 51 is widened in the vicinity of the edge portion 5a on the insertion side, and the back side sheet 2 and the stopper main body 51 are separated from each other in the thickness direction. The transparent sheet 51 has a pressing surface 54 on the back surface side that can hold the front sheet 3 and the document P. The stopper 5 is fixed over two continuous sides of the back side sheet 2 that can be brought into contact with and separated from the front side sheet 3, that is, the open upper edge 1a and the open side edge 1d of the document holder 1. The stopper 5 is positioned so that the back side sheet 2 and the front side sheet 3 are overlapped with the document P sandwiched between the open corners of the document holder 1, so that the front side sheet 3 and the document P are positioned. It functions so as to prevent the back side sheet 2 from being displaced. The expansion portion 53 is mainly composed of a valley fold line 55 extending parallel to the insertion side edge portion 5a so as to connect both ends 56 of the edge portion separated from the back side welding portion via the deformation margin 57. is there. By providing the valley fold line 55 via the deformation margin 57 in this way, the vicinity of the insertion-side edge 5a of the stopper main body 51 is gently deformed, and the insertion-side edge 5a holds the front sheet 3 and the document P. The back side sheet 2 and the stopper body 51 are separated from each other until they can be sufficiently inserted.

FIG. 6 illustrates a mode in which the front side sheet 3 and the document P are positioned on the back side sheet 2 by using the stopper 5. When positioning the front side sheet 3 and the document P using the stopper 5, the predetermined area 34 and the evacuation edge 32 are largely retracted toward the center of the document holder 1 by first bending the front side sheet 3 greatly as shown in the figure. Then, from the state shown in the figure, the evacuation edge 32 is inserted so as to go below the holding surface 54 of the stopper 5 from the edge portion 5a on the insertion side slightly separated from the back sheet 2 and shown in FIG. Make it a state.

FIG. 7 shows a state in which the front side sheet 3 and, for example, about 20 sheets of document P are sandwiched between the holding surface 54 of the stopper 5 and the document supporting surface 21 of the back side sheet 2 using the stopper 5. .. In this state, the first corner opening portion 11 of the first corner portion is appropriately deformed so that the stopper 5 is smoothly positioned by the stopper 5 with the front side sheet 3 and the document P sandwiched therein. ing. Needless to say, the same deformation occurs in the second corner open portion 12 of the second corner portion located at a position facing the first corner portion. As a result, the document holder 1 can smoothly accommodate a large number of documents P, and the document P suddenly falls off from the document holder 1 due to the action of the stopper 5. Is also effectively avoided.

As described above, the document holder 1 constituting the file F according to the present embodiment has the stopper 5 and the back cover H2 because the stopper 5 is provided over the two open sides of the back side sheet 2 and the front side sheet 3. Not only can the document P inserted between the windows be effectively prevented from being pulled out, but also the front cover 3 and the document P can be easily inserted between the back cover H2 and the stopper body 51 by the expansion portion 53 provided in the stopper 5. It is something that can be plugged in. As a result, according to the embodiment, a document holder 1 that can handle the document P well and can reliably protect the document P is realized.

Further, in the present embodiment, the stopper 5 is realized by a simple configuration by forming the expansion portion 53 as a valley fold line 55 formed in the stopper main body 51 in the front view.

Further, in the present embodiment, both ends 56, which are the edges of the valley fold line 55, are positioned at positions separated by the dimension of the deformation margin 57 from the backside welding portion 52, which is the mounting position of the stopper body 51 with respect to the backside sheet 2. , The deformation of the stopper body 51 by the valley fold line 55 is promoted more effectively.

In particular, in the present embodiment, since the first corner opening portion 11 and the second corner opening portion 12 are provided on the first corner portion and the second corner portion positioned diagonally, respectively, the rectangular document P can be obtained. It can accommodate a lot. In addition, with this configuration, it is possible to prevent the corner portion of the rectangular document P from being unnecessarily stretched in the document holder 1, so that a larger number of documents P can be smoothly accommodated.

Then, in order to enable smoother insertion of the front side sheet 3 and the document P into the stopper 5, in the present embodiment, the welding side edge 1c to which the back side sheet 2 and the front side sheet 3 are connected is another sheet, that is, The document holder 1 is unexpectedly displaced or bent when the document P is taken in and out by binding the binding base side so as to function as an edge on the binding base side for binding together with other document holders 1 having the same shape. The stable state is maintained.

Then, in order to realize the file F in which the document holder 1 described above can preferably accommodate the document P, in the present embodiment, the edge portion on the binding base side is attached to the cover body H having the front cover H1 and the back cover H2. It is assumed that the attached portion 1f for the purpose is provided.

In addition, in order to make the document P highly readable, the document holder 1 according to the present embodiment has the front side sheet 3 and the back side sheet 2 made of a transparent resin sheet material.

The file F according to the present embodiment includes the above-mentioned document holder and a cover body H having a front cover, a back cover, and a binding portion H4 for binding the document holder 1 between the front cover H1 and the back cover H2. Since the document holder 1 bound to the binding portion H4 is engaged with the cover body H at the welding side edge 1c which is the edge of the binding base, the document holder 1 is placed on the cover body H and the like. Due to the friction of the paper or the weight of the file F itself containing the paper leaf, the back side sheet 2 does not move unnecessarily and the document P is stably moved to the back side sheet 2 and the front side sheet 3 compared to handling the document holder 1 alone. It is possible to insert it between. And, of course, the document P and the front side sheet 3 can be inserted between the stopper 5 and the back side sheet 2 in a state where the back side sheet 2 is stably placed.
