Description

  The present invention relates to a folded file having a gusseted pocket.

  There is a simple folded file with no fasteners, and there is a file with a pocket to insert a piece of paper inside the file. Some pockets are provided with gussets (widths) so that a large number of paper sheets can be inserted (Patent Documents 1 and 2 below). However, these files are made by separately producing gusseted pocket pieces and pasting them on the file body. Therefore, both material and man-hours are expensive.

  The present invention can reduce the cost by forming the file body, pocket pieces and gusset pieces, which are elements constituting the folded file, into a developed shape, punching them with Thomson, and folding or bonding the punched pieces. It is what I did.

Under the above-mentioned problems, the present invention is a half-folded file having a gusseted pocket on one side or both sides of the inner surface according to claim 1, and forming a fold line that secures the file width on one side or both sides from the center Unfolds the file body, one or two pocket pieces that form a fold line that secures the gusset width outside the file body, and a plurality of gusset pieces that are continuous with the fold line or cutting line. Punched in shape, the pocket piece is folded back with a fold line to make a pocket, but at this time, the gusset piece is cut into a Z shape with a fold line, and the gusseted pocket that makes the gusset width by bonding the remainder raised to the file body With a gusset characterized in that the pocket piece is a continuous one up and down on the side of the file body, and the gusset piece is formed on the upper edge of the upper pocket piece To provide in broken file with a pocket.

Further, the present invention is a middle folded file having a gusseted pocket on one side or both sides of the inner surface according to claim 2, and a file main body formed with a folding line that secures a file width on one side or both sides from the center. , Punching out one or two pocket pieces that form a fold line that secures the gusset width on the outside of the file body, and a plurality of gusset pieces that are continuous with the fold line or cutting line in a developed shape, The pocket piece is folded at the fold line to make a pocket. At this time, the gusset piece is cut into a Z shape at the fold line, and the folded file having a gusseted pocket that attaches the cut and raised portion to the file body to make the gusset width. A pocket with gussets, wherein the pocket pieces are continuous laterally below the file body, and the gusset pieces are formed on the outer pocket pieces in contact with the fold line In broken file with.

  According to the first aspect of the present invention, the file body, the pocket piece and the gusset piece, which are the components of the folded file, have a shape that can be expanded by inserting a fold line or a cut line, so that it can be punched with Thomson and folded after that. Or just glue it, it's easy and cheap. Further, since folding and bonding can be automatically performed by a folding machine, all can be machined, and the cost is further reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1A is a development view of a folded file (hereinafter referred to as a file) having a gusseted pocket of the first example. This file has a file body 1, a pocket piece 2 and a gusset piece 3 on both sides of the center. Have. Two fold lines 4 and 5 are formed at the center of the file main body 1. The fold lines 4 and 5 serve as a front cover and a back cover. A pocket piece 2 that becomes a pocket 8 is separated from the lower side of the file body 1 with two fold lines 6 and 7 therebetween (the upper portions of the fold lines 6 and 7 are cut out). The space between the broken lines 6 and 7 is a gusset 9, and this interval is a gusset width. The material is generally paper.

  The pocket piece 2 is continuous vertically from the fold line 10, and the upper pocket piece 2a is slightly shorter than the outer fold line 7. Several (two in this example) gusset pieces 3 are formed on the upper edge of the upper pocket piece 2a. The gusset piece 3 of this example is provided with two horizontally long strips in a row, of which the part indicated by the solid line is the cut line 11 and the part indicated by the dotted line is the broken lines 12 and 13. is there. The above shape is punched with Thomson to form a pattern.

  Next, a file is formed from the above pattern by the procedure shown in FIGS. 1B and 1C. First, the upper pocket piece 2a is folded back toward the lower pocket piece 2b with the folding line 10 as a boundary. Glue. At this time, no adhesive is applied to the gusset piece 3, but the others are adhered to the entire surface (two sheets are stacked). Then, the pocket piece 2 is folded at the folding lines 6 and 7 and overlapped on the file main body 1. At this time, the two folding lines 12 and 13 of the gusset piece 3 are folded into a Z shape so as to secure the gusset width. The gusset piece 3 is lifted, and an adhesive is applied to portions other than the fold lines 12 and 13 surrounded by the cutting line 11 (thereby, this portion becomes the paste margin 14). Adhere to the file body 1. This operation is performed with the left and right pocket pieces 2.

  According to the above operation, the pocket pieces 2 are overlapped and have high strength, and are folded to the file body 1 side by the fold lines 6 and 7 so that the bottom portion serving as the glue margin 14 is adhered to the file body 2. It is formed in the pocket 8. Therefore, the widths of the folding lines 6 and 7 need to be equal to the width of the gusset piece 3, and this width becomes the gusset width. The size of the pocket 8 is usually smaller than the file body 1 and is formed at the bottom. Further, the upper side and the back side are open so that a paper piece or the like can be easily taken in and out.

  According to this configuration, the bottom portion of the pocket 8 is bridged with respect to the file body 1 only at the interval between the fold lines 12 and 13, and it is considered that the strength is weak when an object is inserted into the pocket 8. Therefore, a receiving piece 16 is formed on the bridging portion of the gusset piece 3 in the file main body 1 and the upper part is defined by a half-moon-like cutting line 15, and this is cut and raised, as shown in FIG. The gusset piece 3 is reinforced to be mounted. The gusset width may be changed between the left and right pockets 8. FIG. 6 shows the completed state.

  FIG. 3A is a development view of the file of the second example, but this example also has a file body 17, a pocket piece 18, and a gusset piece 19. It is also the same that the file main body 17 has two broken lines 20 and 21. In this example, a pocket piece 18 (the outer side is 18a and the inner side is 18b) is formed at the bottom of the file main body 17 with two folding lines 22 and 23 being separated (between the pocket pieces 18). Is notched), and the interval between the fold lines 22 and 23 is a gusset width. In this example, the pocket piece 18a is short, but may be long. The same is true in that this shape is punched out with Thomson to form a pattern.

  Next, a file is formed from the above pattern in the same manner as in the first example in FIGS. 4B and 4C. First, the outer pocket piece 18a is folded into the inner pocket and the piece 18b. Fold back and glue (some are two-layered). Then, the pocket piece 18 is folded at the folding lines 22 and 23 and stacked on the file body 17. At this time, the two folding lines 26 and 27 of the gusset piece 19 are folded into a Z shape in order to secure the gusset width. The gusset piece 19 is lifted, and an adhesive is applied to the portion where the fold lines 26 and 27 surrounded by the cutting line 28 are removed (thereby, this portion becomes the glue 29), and is lifted as shown in FIG. Similarly, the adhesive margin 29 is adhered to the file main body 17 at this time. In this example, since the material is entirely present at the bottom of the pocket 24, the strength is strong and the receiving piece as in the first example is not provided. FIG. 7 shows the completed state.

  The above two examples are basic forms of the present invention, but various pocket formations are possible. For example, there may be one pocket. In that case, a pocket piece or the like is formed only on one side of the file body. In addition, various shapes of the pocket pieces, the direction of expansion, the folding method, and the like are conceivable, and any of them may be adopted. In addition, the pockets may be folded, bent or bonded manually, but can also be automatically performed by a folding machine. According to this, as described above, the cost can be very low.
