Description

  The present invention relates to a document holder that can store and store paper sheets and a file including the document holder.

  2. Description of the Related Art Conventionally, a document holder that is mainly composed of a sheet-like material such as a synthetic resin sheet and that can accommodate paper sheets between a front cover and a back cover is well known. As such a document holder, a document holder called a so-called pocket or a clear holder, and a cover body, which are made of a transparent synthetic resin sheet capable of visually recognizing the contents described on the paper sheet from the outside. Can include a file formed by closing the document holder (see, for example, Patent Document 1).

  A document holder having two continuous sides open or substantially open as described in Patent Document 1 is easy to put in and take out paper sheets, but the stored paper sheets are unexpectedly moved outward. It may happen that it falls out.

  In the document holder described in the same document, as shown in FIG. 4 in particular, a protruding portion is provided that protrudes from the other side of either of the two sides where either one of the front and back sheets is opened, and is folded back to the other side. In this way, it is possible to prevent the paper sheet from being removed from the portion.

JP 2009-29100 A

  However, in the document holder described in Patent Document 1, it is conceivable that the document holder can be pulled out from one side that is still open, or the bending of the protruding portion can be extended. Here, in order to more effectively suppress the removal of the paper sheets, it is conceivable to provide a plurality of protruding portions disclosed in FIG. 4 of the same document or to have a configuration and shape in which bending is difficult to extend. In such a case, the operation of taking paper sheets in and out of the document holder becomes very complicated.

  That is, at present, there is a document holder that can realize a state in which the removal of the paper sheet can be prevented and a state in which the paper sheet can be easily taken in and out while being able to effectively suppress the removal of the paper sheet. It has been demanded.

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

  That is, the document holder according to the present invention is configured such that the back side sheet supporting the paper sheets from the back side and the two continuous sides to the back side sheet can be contacted and separated, and the other sides are connected to each other. A front side sheet that is arranged so that paper sheets can be inserted and removed between the back side sheet and the back side sheet, and the back side sheet and the back side sheet are attached to the back side sheet in the vicinity of the corner where two sides that can contact and separate are continuous A stopper main body having a sheet shape capable of inserting and holding a corner portion of the front side sheet between the back side sheet and an edge of the insertion side into which the corner portion of the front side sheet in the stopper main body is inserted from the back side sheet. And a stopper having an expanded portion formed in the vicinity of the edge on the insertion side so as to be separated.

  If it is such, since the stopper is provided over the open two sides of the back sheet and the front sheet, it is possible to effectively prevent the paper sheets inserted between the stopper and the back cover from being pulled out. In addition, the front side sheet and the paper sheet can be easily inserted between the back cover and the stopper main body by the expanding portion provided in the stopper. As a result, according to the present invention, it is possible to provide a document holder capable of reliably protecting a paper sheet while improving the handling of the paper sheet.

  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 a 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 of the valley fold line at a position away from the attachment position with respect to the back sheet in the stopper body.

  The document holder has a rectangular shape when viewed from the front, and in order to more smoothly and smoothly accommodate paper sheets having a predetermined shape, two sides on which the back side sheet and the front side sheet can be contacted and separated are continuous. A first corner opening portion provided by separating the stopper and the back side sheet at a first corner portion which is a corner of the corner portion, and the front side sheet and the second corner portion which is a corner facing the first corner portion. It is desirable to provide a second corner opening portion provided by separating the back side sheet. This prevents the corner portion of the rectangular paper sheet from being unnecessarily stretched in the document holder, so that more paper sheets can be accommodated smoothly.

  And in order to be able to insert the front side sheet and the paper sheet into the stopper more smoothly, any one side to which the back side sheet and the front side sheet are connected is bound together with the other sheets. What is necessary is just to set it as the stable state by binding the binding base side as what comprised the edge part of the side.

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

  And in order to implement | achieve the file in which the document holder mentioned above can accommodate paper sheets suitably, it has a to-be-attached part for attaching the edge part of a binding base side to the cover body which has a front cover and a back cover. It is desirable to make it.

  In addition, in order to allow the above-mentioned document holder to be suitably used as an element of a file or as a document holder alone, a paper that is perforated with a predetermined interval between the edges on the binding base side. It is desirable to have a plurality of binding holes for binding leaves.

  In order to make the paper sheet highly viewable, the front side sheet and the back side sheet are preferably made of a transparent resinous sheet material.

  The file according to the present invention includes the document holder described above, and a front cover, a back cover, and a cover body having 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 portion is engaged with the cover body on the binding base side, so the friction between the cover body and the desk on which it is placed, or the paper sheets The backside sheet can be stably inserted between the front side sheet and the back side sheet without moving the back side sheet unnecessarily as compared with handling the document holder alone by the weight of the stored file itself. And of course, it is possible to insert a sheet or a front sheet between the stopper and the back sheet while the back sheet is stably placed.

  Since the present invention has the above-described configuration, it is possible to provide a document holder that can reliably protect the paper sheets while improving the handling of the paper sheets.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The file F according to the present embodiment is formed by binding a plurality of document holders 1 to the cover body H by, for example, welding of resin, and is usually also called a clear book. In the file F, when the cover body H is opened, the contents of the document P, which is a paper sheet accommodated in the document holder 1 that is bound, can be clearly seen from the outside through a transparent resin sheet. It has become. Note that the file F is provided with a label holder capable of storing the label in a part of the surface of the cover body H, but the illustration and description of the label holder are omitted in the present embodiment.

  In the present embodiment, the cover body H is mainly composed of a colored resin plate having a shape-retaining property, and can be appropriately curved by being interposed between the front cover H1, the back cover H2, and the front cover H1 and the back cover H2. It has a deformed cover H3 and a binding portion H4 that is provided inside the deformed cover H3 and to which the document holder 1 is attached and bound. The deformed cover H3 is a resin plate so that the front cover H1 and the back cover H2 can be separated from each other by a required dimension so as to correspond to the thickness dimension over which the document holder 1 and the document P accommodated in the document holder 1 are stacked without gaps. Are provided in parallel with a plurality of equal intervals. As a result, the cover body H can be bent or bent as appropriate at the position of the hinge H5, and the front cover H1 and the back cover H2 are separated by a thickness dimension corresponding to the thickness that can be appropriately changed depending on the cover document holder 1 and its contents. Can be made. As a result, the file F may cause an unnecessary gap between the front cover H1 and the back cover H2, or there is too much to be stored on the binding base side, and the lip side facing the binding base side is unnecessary. Compact storage is realized without opening. In addition, as an aspect of the cover which can show | play the said effect | action in this embodiment, the aspect comprised entirely with the resin raw material which does not have shape retention property can be mentioned.

  Then, in this file F, when the cover body H is opened as shown in FIG. 2, the same number of document holders 1 are stacked so as to overlap the front cover H1 and the back cover H2, respectively, in the state in which no storage is stored. A plurality of document holders 1 are bound to H4 by welding. However, the plurality of document holders 1 are all provided with the front side sheet 3 on the side close to the front cover H1. In other words, the plurality of document holders 1 are configured so that transparent resin sheets are folded and bound so as to be symmetrical on the front cover H1 side and the back cover H2 side, and all face the same direction.

  Here, in the file H according to the present embodiment, a plurality of document holders 1 such as two or four are integrally formed by bending and welding one transparent resin sheet, and these transparent holders are formed. The resin sheet is welded to the binding portion H4 of the cover body H in a state where a plurality of resin sheets are laminated. However, this embodiment is not limited to a mode in which the plurality of document holders 1 are integrally formed. Therefore, in the following description, the individual document holder 1 will be described.

  The document holder 1 according to the present embodiment is also referred to as a clear holder. As shown in FIGS. 1 to 7, the document P having a rectangular shape as an accommodation is easily described from the outside. It is for accommodating and storing as a state that can be visually recognized.

  Here, the document holder 1 according to the present embodiment is configured so that the back side sheet 2 that supports the document P from the back side and the two continuous sides of the back side sheet 2 can be contacted and separated, and the other sides are connected to each other. Accordingly, the front side sheet 3 arranged so that the document P can be inserted and removed between the back side sheet 2 and the back side sheet 2 that can be contacted / separated and the two sides that can be contacted / separated by the front side sheet 3 are continuous. A stopper main body 51 which is attached to the back sheet 2 in the vicinity of the corner and forms a sheet shape capable of inserting and holding the corner of the front sheet 3 between the back sheet 2 and the corner of the front sheet 3 in the stopper main body 51 is inserted. And a stopper 5 having a widened portion 53 formed in the vicinity of the insertion-side edge 5a so as to separate the insertion-side edge 5a 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 mainly includes a back side sheet 2 and a front side sheet 3 which are formed by appropriately bending and welding a transparent and transparent sheet material. Specifically, the document holder 1 has a substantially rectangular shape in which the other side is joined so that two continuous sides of the back side sheet 2 and the front side sheet 3 are opened. In the present embodiment, the material forming the back sheet 2 and the front sheet 3 is a resinous sheet material such as polypropylene, but of course, other resin materials such as polyethylene and polyethylene terephthalate may be used. Furthermore, the back sheet 2 may be made of a material different from the front sheet 3.

  This document holder 1 has an open upper edge 1a configured so that the back side sheet 2 and the front side sheet 3 can be contacted / separated over the entire area in order to open two continuous sides and join the other two sides. A bottom edge 1b formed by folding back a resin material at an end facing the open upper edge 1a, and a binding base side joined by welding one side end of the open upper edge 1a and the bottom edge 1b in a band shape And an open side edge 1d configured so that the back side sheet 2 and the front side sheet 3 can be contacted / separated over substantially the entire area at the end facing the welding side edge 1c. Yes.

  That is, in the present embodiment, the welding 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 with another sheet, that is, a plurality of other document holders 1, on the binding base side. Part. In addition, in this embodiment, the welding side edge 1c has a mounted portion 1f that can be welded to be bound to the binding portion H4 of the file F described above.

  In addition, the document holder 1 according to the present embodiment further includes a stopper 5 that can sandwich the front sheet 3 and the document P on the back sheet 2 side. By providing the stopper 5, the document holder 1 separates the stopper 5 and the back sheet 2 at the first corner portion, which is a corner of the corner where the two sides where the back sheet 2 and the front sheet 3 can contact and separate are continuous. And a second corner opening portion 12 provided by separating the front sheet 3 and the back sheet 2 at a second corner portion facing the first corner portion. A specific configuration of the stopper 5 will be described later.

  The back sheet 2 has a rectangular shape so as to support the document P from the back side, and a document support surface 21 for supporting the document P, that is, the document P, is provided over substantially the entire surface on the side facing the front sheet 3. Have. Further, in the present embodiment, the back sheet 2 has a stopper mounting portion 22 for mounting the above-described 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 the resin material is front-faced in a transparent surface 30 having a transparent surface, and in an area facing the open upper edge 1 a and the open side edge 1 d. A retraction edge 32 formed to be slightly recessed in view and a recess 33 formed by recessing a resin material in a substantially triangular shape in the vicinity of the welding side edge 1c of the open upper edge 1a. In the present embodiment, as shown in FIGS. 2 and 3, the retraction edge 32 is formed so that the stopper mounting portion 22 and the stopper 5 of the back sheet 2 are partially exposed to the front side. Further, the formation of the concave portion 33 facilitates the flexible deformation of the front side sheet 3 in the vicinity of the welding side edge 1s in the front side sheet 3, and for the user to separate the back side sheet 2 and the front side sheet 3 in the thickness direction. Fingers can be easily inserted between the back sheet 2 and the front sheet 3. In the present embodiment, the front side sheet 3 has a predetermined region 34 at a place where two sides such as the open upper edge 1a and the open side edge 1d are continuous, that is, near the corner.

  Here, in this embodiment, as shown in FIGS. 5 to 7, the document holder 1 has two continuous sides in which the back sheet 2 and the front sheet 3 can contact and separate in addition to the back sheet 2 and the front sheet 3. A stopper main body 51 that is attached to the back side sheet 2 in the vicinity of the corner and has a sheet shape capable of inserting and holding the corner of the front side sheet 3 between the back side sheet 2 and a corner of the front side sheet 3 in the stopper main body 51 is inserted. It is characterized by comprising a stopper 5 having a widened portion 53 formed in the vicinity of the insertion-side edge 5a so as to separate the insertion-side edge 5a from the back sheet 2. Hereinafter, the configuration of the stopper 5 will be described.

  The stopper 5 is made of a resin material that forms a sheet that is formed separately from the resin material that forms the front sheet 3 and the back sheet 2. Specifically, the stopper 5 functions so as to prevent the front sheet 3 and the document P from being displaced from the back sheet 2. The stopper 5 is attached to the back sheet 2 in this embodiment, and the front sheet 3 and the document P are inserted between the cover and the back sheet 2 from the edge 5a on the insertion side. Deviation with respect to the back sheet 2 can be prevented.

  The stopper 5 will be described in detail. A stopper main body 51 having a trapezoidal shape in front view, and a back side welding portion 52 which is an attachment position welded to the back side sheet 2 in a portion corresponding to the inclined side of the stopper main body 51 are different from each other. In the vicinity of the edge portion 5a on the insertion side, the stopper main body 51 is expanded, 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 holding surface 54 that can hold the front side sheet 3 and the document P on the back side. The stopper 5 is fixed over two continuous sides of the back sheet 2 that can be brought into contact with and separated from the front sheet 3, that is, the open upper edge 1 a and the open side edge 1 d of the document holder 1. The stopper 5 is positioned in a state where the back side sheet 2 and the front side sheet 3 are overlapped in a state where the document P is sandwiched between the open corners of the document holder 1 so that the front side sheet 3 and the document P are overlapped. It functions so as to prevent displacement of the backside sheet 2 from the back side. The expanding portion 53 is mainly composed of a valley fold line 55 extending in parallel to the insertion-side edge portion 5a so as to connect both ends 56, which are edge portions separated from the back-side welded portion, via a deformation margin 57. is there. By providing the valley fold line 55 through the deformation margin 57 in this way, the vicinity of the edge 5a on the insertion side in the stopper main body 51 is gently deformed, and the edge 5a on the insertion side allows the front sheet 3 or document P to be deformed. The back sheet 2 and the stopper main body 51 are separated until they can be inserted sufficiently.

  FIG. 6 illustrates a state in the middle of performing the operation of positioning the front side sheet 3 and the document P on the back side sheet 2 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 retraction edge 32 are largely retracted toward the center of the document holder 1 by first largely bending the front side sheet 3 as shown in FIG. Then, from the state shown in FIG. 5, the retracting edge 32 is inserted from the insertion side edge 5a slightly spaced from the back sheet 2 to the lower side than the pressing surface 54 of the stopper 5, and shown in FIG. State.

  FIG. 7 shows a state in which the front side sheet 3 and, for example, about 20 sheets of document P stacked using the stopper 5 are sandwiched between the pressing surface 54 of the stopper 5 and the document support surface 21 of the back side sheet 2. . In this state, the first corner opening portion 11 of the first corner portion is appropriately deformed so that the stopper 5 smoothly positions the document P and the front sheet 3 with the stopper 5 interposed between the front sheet 3 and the document P. ing. Needless to say, the same deformation occurs in the second corner opening portion 12 of the second corner portion positioned at the position facing the first corner portion. Thereby, even if the document holder 1 accommodates many documents P, the document holder 1 can be accommodated smoothly, and the document P is unexpectedly dropped 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 this embodiment has the stopper 5 and the back cover H2 because the stopper 5 is provided over the two open sides of the back sheet 2 and the front sheet 3. In addition to effectively preventing the document P inserted between the front cover 3 and the stopper body 51, the front sheet 3 and the document P can be easily removed between the back cover H2 and the stopper main body 51 by the expanding portion 53 provided in the stopper 5. It can be plugged in. As a result, according to the embodiment, the document holder 1 that realizes good handling of the document P and can reliably protect the document P is realized.

  In the present embodiment, the expanded portion 53 is a valley fold line 55 formed in the stopper main body 51 in a front view, thereby realizing the stopper 5 with a simple configuration.

  Further, in the present embodiment, both ends 56 that are the edges of the valley fold line 55 are positioned at positions that are separated from the back-side welded portion 52 that is the mounting position of the stopper main body 51 with respect to the back-side sheet 2 by the dimension of the margin 57. The deformation of the stopper main body 51 by the valley fold line 55 is more effectively urged.

  In particular, in the present embodiment, the first corner opening portion 11 and the second corner opening portion 12 are provided in the first corner portion and the second corner portion positioned on the diagonal line, respectively. Many can be accommodated. In addition, the configuration prevents the corner portion of the rectangular document P from being unnecessarily stretched in the document holder 1, so that more documents P can be accommodated smoothly.

  And in order to be able to insert the front side sheet 3 and the document P into the stopper 5 more smoothly, in this embodiment, the welding side edge 1c to which the back side sheet 2 and the front side sheet 3 are connected is another sheet, It functions as an edge of the binding base side for binding together with other document holders 1 having the same shape, and the binding of the binding base side causes the document holder 1 to be unexpectedly displaced or bent when the document P is put in and out. A stable state is maintained.

  In order to realize the file F in which the document holder 1 can accommodate the document P, the binding base side edge is attached to the cover body H having the front cover H1 and the back cover H2. It is assumed that it has a mounted portion 1f for the purpose.

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

  The file F according to the present embodiment includes the above-described document holder, and a front cover, a back cover, and a cover body H having a binding portion H4 that binds the document holder 1 between the front cover H1 and the back cover H2. Therefore, 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 back side sheet 2 and the front side sheet 3 are stably moved without moving the back side sheet 2 unnecessarily as compared to handling the document holder 1 alone by the weight of the file F itself containing the document P as a paper sheet. It becomes possible to insert between. Of course, the document P and the front sheet 3 can be inserted between the stopper 5 and the back sheet 2 with the back sheet 2 stably placed.

  <Modification>

  Hereinafter, modified examples of the present embodiment will be described with reference to FIGS. In the modified example, the same reference numerals are given to the components corresponding to the constituent elements of the embodiment, and the detailed description thereof is omitted.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The document holder 1 according to the present embodiment is also referred to as a security holder. As shown in FIGS. 8 to 11, a document P that is a rectangular paper sheet as a stored item has a description content P <b> 1. It is intended to be housed and stored in a state that cannot be substantially visually recognized from the outside. By using such a document holder 1, even if the document P is a document in which personal information or the like is described, for example, a number indicating an identification number such as a My Number described in the header portion of the document P or the like Important information such as a seal can be stored and stored in a suitably concealed state.

  In this modification, the document holder 1 is formed by welding a bulging portion of the resin material constituting the front side sheet 3 to the back side sheet 2 in a certain region from the bottom edge 1b of the open side edge 1d. The spill stopper 1e and the binding side edge 1c further have binding holes 1h which are openings formed at, for example, four locations at equal intervals in the vertical direction. By providing the anti-spillage 1e, even the document P simply sandwiched between the back side sheet 2 and the front side sheet 3 is not easily dropped from the open side edge 1d side. In the present embodiment, the binding holes 1h can be suitably bound to a binder or the like provided with a binding tool having a general four-hole or two-hole structure. However, the presence / absence and the number of the binding holes 1h may be appropriately configured depending on the storage mode of the document holder 1 and the document P to be stored. For example, by further increasing the number of binding holes 1h, it is possible to adopt a different aspect with high versatility, such as a so-called clear book replacement sheet.

  The front side sheet 3 has a substantially rectangular shape corresponding to the outer shape of the back side sheet 2, and has an opaque surface 31 with an opaque surface, a retraction edge 32 similar to the above embodiment, and a substantially triangular shape in the vicinity of the spill-proof 1 e. And a recess 33 formed by recessing a resin material into the shape. In the present modified example, the concave portion 33 is formed in the vicinity of the spill stopper 1e, whereby the front side sheet 3 in the vicinity of the spill stopper 1e is flexibly deformed in the front side sheet 3, and for the user, the back side sheet 2 and the front side sheet 3 The fingers are easily inserted between the back sheet 2 and the front sheet 3 so as to be separated in the thickness direction. And in this embodiment, this front side sheet | seat 3 is the predetermined area | region 34 set according to the description content of the document P which is going to accommodate the location vicinity where two sides, such as the open upper edge 1a and the open side edge 1d, continue. It is said. This is because in this modification, it is assumed that an important part of the description contents of the document P is arranged in a part of the document P in which the predetermined area 34 is overlaid.

  And the document holder 1 which concerns on this modification further has the stopper 5 similar to the said embodiment which can pinch | toe the front side sheet | seat 3 and the document P in the back side sheet | seat 2 side, and the exposure window 4 pierced by the front side sheet | seat 3 side. Yes.

  The front window 4 includes a through-hole element 40 that is an embodiment of an opening or a slit formed in the predetermined portion 34 of the front sheet 3 described above.

  The stopper 5 has substantially the same aspect as the above-described embodiment except that the stopper 5 is made of a transparent resin material having a sheet shape that is formed separately from the resin material constituting the front side sheet 3 and the back side sheet 2. It is.

  Here, the document holder 1 according to the present modification is provided with an opening window 4 that is one form of an opening or a slit, and by bending a part of the front sheet 3, the through-hole element 40 is slid against the document P. It is assumed that the description content of the document P can be read when it is moved.

  As described above, even if it is configured as in the present modification, it can be used as the document holder 1 alone, or can be used as the file F by binding to a binding tool using the binding hole 1h. The same effect as the embodiment can be obtained.

  As mentioned above, although one Embodiment of this invention and each modification were demonstrated, the specific structure of each part is not limited only to embodiment mentioned above, A various deformation | transformation is carried out in the range which does not deviate from the meaning of this invention. Is possible. For example, in the above-described embodiment, a valley fold line extending in parallel with the insertion-side edge is disclosed as each opening, but, of course, a mountain fold line extending from the insertion-side edge may be used. In addition, the expanded portion is not limited to the fold line. For example, the resin forming the stopper main body is welded to the back side sheet in a previously curved state, or the resin that has been curved and deformed in advance is welded to the back side sheet. Or you may.

  Further, for example, in the above embodiment, the document holder mainly including only the front cover and the back cover is disclosed, but of course, a mode having a partition formed integrally or separately between the front cover and the back cover. Even so, the present invention can be suitably applied. Moreover, although the aspect which provided the binding edge and the aspect which provided the binding hole to the cover body by welding in the said embodiment, the rail groove | channel for document holder attachment was provided in the cover body, for example, A slider that can be attached to the rail groove by a sliding operation may be provided on the edge on the binding base side.

  The colors of the back side sheet, the front side sheet, and the stopper may be transparent or translucent. Furthermore, other detailed configurations such as specific shapes and materials of the cover and the display window can be variously modified without departing from the gist of the present invention.
