Description

  The present invention relates to a paper clip, and more particularly, to a paper clip for storing documents such as a manual, a guide, and a plan.

  A paper clip is a well-known stationery known as a document holder, a paper holder, a folder, a file, a binder, etc., and various documents and drawings such as manuals, guides, and planning documents (hereinafter “documents”). Used to store and move in a clean condition. In recent years, paper sandwiches are made of resin sheets from the viewpoint of reducing manufacturing costs and increasing durability.

  The above-mentioned paper sandwicher has a front cover and a back cover formed by folding a molded original sheet at the center to form each square, and a pocket is provided on the inner surface of the front cover or the back cover. A tongue-like stopper is attached to the upper center or left edge of the inner surface, and a part of the document is sandwiched between the pocket and the stopper to prevent the document from falling off. Furthermore, a method has been proposed in which pockets and stoppers are made of a charging material, and the document is prevented from popping out due to electrostatic adsorption.

JP 2000-71663 A JP 2007-76351 A

  By the way, in the case of a resin paper sandwich, since the electrostatic adsorption function cannot be sufficiently exhibited depending on the material configuration, the paper quality of the document, and the use state, a structural improvement that can surely prevent the document from jumping out is desired. . Therefore, it is conceivable to provide both a pocket and a stopper. However, when a pocket and a stopper are provided, it is difficult to use because the closed stopper must be held open once and a document must be inserted into the pocket. Also, depending on the frequency of use, the stopper has an open wrinkle, making it easier for documents to pop out.

  The present invention has been made in view of the above-mentioned circumstances, and its purpose is a paper-made paper sandwicher for storing documents, which is easy to use and ensures that the documents are ejected and dropped during handling. It is to provide a paper sandwich that can be prevented.

  In order to solve the above problems, in the present invention, by providing a left pocket and a right pocket on the outer corner side of the lower end of the inner surface of the rectangular front cover and the back cover, respectively, the lower end portion and the outer corner portion of the document are provided. Holds and regulates the downward and lateral dropout of the document, and a fold-like tongue-shaped stopper is straddled between the front and back covers at the upper end of the valley fold, which is the boundary between the front and back covers. Thus, the upper edge of the document is held in a state where the stopper is folded, and the upward jumping of the document is restricted.

  That is, the gist of the present invention is a resin paper sandwich formed by folding and welding a molded original sheet to form a front cover and a back cover of each square. A left pocket and a right pocket are provided on the corners on the outer sides of the lower ends of the front cover and the back cover, respectively, and a tongue piece is provided at the upper end of the valley fold that is a boundary between the front cover and the back cover. The stopper is provided with a stopper-forming piece protruding from the center of the upper edge of the original sheet, folded back into a valley fold along the upper edge, and further along the valley fold. The paper clip is formed by folding back into a valley fold and straddling the front cover and the back cover.

  According to the paper sandwicher according to the present invention, left and right pockets for storing corners of documents are provided on a front cover and a back cover in a spread state, and the upper end of a valley fold that is a boundary between the front cover and the back cover is provided. A folding tongue-shaped stopper is provided across the front and back covers. Insert the lower corner of the document into the left and right pockets, and put the stopper on the upper edge of the document. By simply folding the front and back covers, documents can be stored easily, and after storage, the documents can be reliably prevented from jumping out or falling off.

It is a perspective view of the state which spreads and shows the structure of the paper clip concerning the present invention. It is the top view which showed an example of the original sheet | seat before the folding process of the paper clamp concerning this invention. It is a top view which shows partially the structure of the folding | turning part in the original sheet | seat of FIG.

  The paper nip of the present invention is a resin paper nip constructed by folding and welding the original sheet S molded in a predetermined shape as shown in FIG. 2, as shown in FIG. , A front cover 1 and a back cover 2 formed in squares. FIG. 2 is a view of the original sheet S as a main body constituting member before folding from the inner side, and reference numerals 70 to 76 in the drawing denote valley folded portions as folded portions used in folding. Is shown.

  As the constituent material of the paper sandwich of the present invention, in other words, the resin constituting the original sheet S, polyolefins such as polypropylene and polyethylene are used in consideration of moldability, cost, and influence on the environment. From the viewpoint of obtaining rigidity and flexibility, polypropylene is preferably used. Such a resin may be a transparent resin or a colored resin. The thickness of the original sheet S is set in consideration of rigidity, durability, cost, etc., and is usually 0.2 to 0.5 mm, preferably 0.3 to 0.4 mm.

  As shown in FIG. 2, the original sheet S is a single punched sheet, and the front cover 1 and the back cover 2 are usually the same by folding the central part of the original sheet S. Formed in a planar dimension. Reference numeral 70 indicates a valley fold portion that is folded as a boundary between the front cover 1 and the back cover 2. Each size of the front cover 1 and the back cover 2 is set to, for example, 305 to 315 mm in length and 215 to 225 mm in width when storing A4 size paper in a single or half-folded paper size, When storing a B5-size document with the same paper size, the length is set to 255 to 265 mm, and the width is set to 185 to 195 mm.

  The paper clip of the present invention has a structure as shown in FIG. 1 in order to enhance functionality. That is, in the paper sandwich of the present invention, in the spread state (the state in which the inner surfaces of the front cover 1 and the back cover 2 are shown), the document is sandwiched. Are each provided with a left pocket 3 and a right pocket 4. A tongue-like stopper 5 is provided at the upper end of the valley fold 70 that is the boundary between the front cover 1 and the back cover 2 in order to prevent the document from jumping upward.

  The left pocket 3 of the front cover 1 includes a lower left corner of the front cover 1 and is connected to the left vertical edge and the lower edge of the front cover 1. Further, the right pocket 4 of the back cover 2 includes the lower right corner of the back cover 2 and is connected to the right vertical edge and the bottom edge of the back cover 2. The left pocket 3 and the right pocket 4 are formed in, for example, a fan shape that is opened at 90 ° around each of the lower end corners. As described above, the left pocket 3 and the right pocket 4 are provided at the lower corners of the front cover 1 and the back cover 2 to prevent the document from falling off to the lower side and the side cover 1 and The rigidity of the lower end part and the side edge part of the back cover 2 can be increased.

  Furthermore, although illustration is omitted, the left pocket 3 and / or the right pocket 4 may be provided with a notch for inserting an information medium or a card. For example, the left pocket 3 of the front cover 1 is provided with a notch for inserting a small document such as a membership card or a card, and the right pocket 4 of the back cover 2 is a cut for inserting a CD or DVD. Included.

  In the present invention, in order to prevent the document from jumping upward, the stopper 5 is formed by folding back the stopper-forming piece 5a formed on the original sheet S as shown in FIG. Specifically, the stopper forming piece 5a protruding from the center of the upper edge portion of the original sheet S is folded back along the upper edge portion into a valley fold, and in the folded state, further into the valley fold portion 70 described above. Along the way, it is folded back into a valley fold. That is, the stopper 5 bends the stopper forming piece 5a toward the inner surfaces of the front cover 1 and the back cover 2 at the valley fold 75, and when the cover cover 1 and the back cover 2 are folded in this state, together with the valley fold 70. The stopper forming piece 5 a is further bent at the valley fold portion 76 to be formed across the front cover 1 and the back cover 2. In addition, the valley folding part 76 is a site | part folded in the state where the stopper formation piece 5a was folded inward.

  The stopper 5 in the open state, in other words, the stopper-forming piece 5a before being folded can be formed in an appropriate shape such as a quadrangle. Formed into an oval shape. The width of the stopper 5 in the direction along the upper edge of the front cover 1 and the back cover 2 (left and right direction in FIG. 2) is set to 23 to 41% of the length of the upper edge from the front cover 1 to the back cover 2. Further, the height of the stopper 5 in the direction along the valley fold 70 (vertical direction in FIG. 2) is 13 to 13 times the length of the valley fold 70 (length in the vertical direction of the front cover 1 and the back cover 2). It is set to 19%. In the case of a paper clamp for storing A4 size, the width of the stopper 5 is about 100 to 180 mm, and the height of the stopper 5 is about 40 to 60 mm.

  The reason why the size of the stopper 5 is defined in the above range is as follows. In other words, when the width of the stopper 5 is less than 23% of the length of the upper edge, the rigidity of the valley fold 76 is larger than the size of the stopper 5 and the folding is difficult. Further, when the width of the stopper 5 exceeds 41% of the length of the upper edge, the stopper 5 becomes too large and it becomes difficult to hold the document with the stopper 5 when storing the document. On the other hand, when the height of the stopper 5 is less than 13% of the length of the valley fold 70, the document may come off from the stopper 5 when a document smaller than the standard is stored. When the length exceeds 19% of the length of the valley fold 70, the stopper 5 becomes too large and the opening / closing operation becomes difficult.

  The paper sandwich of the present invention is manufactured by forming the left pocket 3 and the right pocket 4 by punching the raw resin sheet to create the original sheet S and then folding and welding the original sheet. Is done. As is well known, the punching is performed using a punching machine such as a Victoria punching machine, a flat plate punching machine, or a rotary die cutter. That is, the original sheet S is formed by a single punched sheet.

  As shown in FIG. 2, the left pocket 3 is a left pocket that protrudes downward from the lower edge portion of the front cover 1 in the original sheet S and extends in a substantially straight line from the vertical edge portion of the front cover. A left pocket that is folded back into the valley fold (inside) along the lower edge of the front cover 1 while the formed piece 3a is folded leftward from the vertical edge of the cover 1 and folded back into the valley fold (inside) The binding margin piece 6 is constructed by welding to the vertical edge portion of the left pocket forming piece 3a. Reference numeral 71 represents a valley fold portion that is a folded portion of the left pocket forming piece 3 a, and reference numeral 73 represents a valley fold portion that is a folded portion of the left pocket binding margin piece 6.

  Similarly to the left pocket 3, the right pocket 4 projects downward from the lower edge of the back cover 2 in the original sheet S, and the vertical edge extends substantially linearly from the vertical edge of the back cover. The right pocket forming piece 4a was folded back along the bottom edge of the back cover 2 in a valley fold (inside), and was projected rightward from the vertical edge of the back cover 2 and folded back into a valley fold (inside). The right pocket binding margin piece 8 is welded to the vertical edge portion of the right pocket forming piece 4a. Reference numeral 72 represents a valley fold portion that is a folded portion of the right pocket forming piece 4 a, and reference numeral 74 represents a valley fold portion that is a folded portion of the right pocket binding margin piece 8.

  Further, as shown in FIGS. 2 and 3, in the present invention, at the time of the punching process described above, three folded grooves are formed in each folded portion. That is, the valley folding part 70 which is the boundary between the front cover 1 and the back cover 2, the valley folding parts 71 and 72 of the left pocket forming piece 3a and the right pocket forming piece 4a, the left pocket binding piece 6 and the right pocket binding piece 8 Three folded grooves are formed in each of the valley folds 73 and 74 and the valley folds 75 and 76 of the stopper forming piece 5a. Although not shown, these folded grooves are formed in a V shape or a concave cross section perpendicular to the extending direction, and are provided as a set of three in parallel at a pitch of 2.5 to 3.5 mm. In the present invention, folding grooves such as those described above are provided in each of the valley fold portions 70 to 76 to facilitate folding processing, and when used, a plurality of thick documents are placed in the left pocket 3 and the right pocket. It can be stably stored in the pocket 4 and the stopper 5 can be securely put on the upper end of the document.

  When using the paper sandwicher of the present invention, as shown in FIG. 1, in a state where the front cover 1 and the back cover 2 are opened, first, A4 size (or A3 size with spread), B5 size (or B4 with spread) The lower corner of the document (not shown) is inserted into the left pocket 3 on the front cover 1 and / or the right pocket 4 on the back cover 2. Next, the stopper 5 in the opened state is folded over the upper edge of the document, and the front cover 1 and the back cover 2 are closed so that the stopper 5 is further folded at the valley fold 76.

  When the documents are stored and stored in the bookshelf or drawer as described above, the left pocket 3 and the right pocket respectively provided on the inner surfaces of the front cover 1 and the back cover 2 in the paper sandwicher of the present invention. 4 holds the lower end portion and the outer corner portion of the document, and regulates the document to drop out downward and to the side. In addition, a tongue-like stopper 5 having a folding structure provided over the front cover 1 and the back cover 2 at the upper end of the valley fold 70 holds the upper edge of the document and restricts the document from jumping out. To do. In particular, the stopper 5 folded in two at the two valley folds 75 and 76 is, for example, a three-dimensionally sandwiched folded portion at the center upper part of a two-page spread of A3 size or B4 size. Slip can be more reliably regulated.

  Therefore, according to the present invention, simply inserting the lower corners of the document into the left pocket 3 and the right pocket 4, covering the upper edge of the document with the stopper 5, and folding the front cover 1 and the back cover 2 is simple. Documents can be stored, and after storage, it is possible to reliably prevent the document from jumping out and dropping out in each direction.
