Description

This invention relates to a file creation sheet that allows documents and other items to be stored individually using dividers, and a file that uses this file creation sheet.

So-called clear files are available on the market, which allow documents and other items to be stored separately using dividers. These clear files are made by folding a single plastic sheet multiple times to create a front and back cover with dividers between them, and then heating and welding the bottoms of these together.

For example, Utility Model Registration No. 3027947 discloses a document file case characterized in that "a flat sheet portion 1 is folded in half two-ply, and the folded flat sheet portion is further folded in half in a direction perpendicular to the folding direction of the folded flat sheet portion to form a four-fold flat sheet portion, and only the inner folded sheet surface of the four-fold flat sheet portion is separated into two along a notch line along the entire length of the fold line, or, without separating the inner folded sheet surface of the four-fold flat sheet portion, a portion of the inner folded sheet surface 1 of one of the four-fold flat sheet portions is cut out in the direction of the bottom of the fold to form a connecting piece, which is then folded and clamped or adhered to the outer surface of the outer folded sheet surface on the opposite side."

In the above-mentioned file case, the flat sheet portion 2 is folded in four to form the four-fold flat sheet portion 14, and then the connecting piece 12 cut and raised from the folded inner sheet surface 10a is tightly folded onto the outer surface of the case back 9, which is the folded outer sheet surface 7b at the edge, and welded to it by heat sealing.

However, although the file cases mentioned above are made by heat sealing, there are cases where the heat-sealed parts crack. Some users also demand paper files. Furthermore, there is a demand for files that can be made from a single sheet without waste.

Utility Model Registration No. 3027947

The present invention was conceived in light of the above-mentioned circumstances, and its objective is to provide a file-making sheet that can be constructed from a single sheet without waste, and a file that is made using this file-making sheet without heat welding.

In order to solve the above-mentioned problem, a file creation sheet according to a first aspect has a first sheet portion that becomes the front side when configured as a file, a second sheet portion that becomes a divider when configured as a file, a third sheet portion that becomes a divider when configured as a file, and a fourth sheet portion that becomes the back side when configured as a file; the first sheet portion has a first spine portion that forms the spine when configured as a file, the second sheet portion has a second spine portion that forms the spine when configured as a file, the third sheet portion has a third spine portion that forms the spine when configured as a file, and the fourth sheet portion has a fourth spine portion that forms the spine when configured as a file; the first sheet portion has a first lower end portion that forms the bottom end when configured as a file, the third sheet portion has a third lower end portion that forms the bottom end when configured as a file, and the fourth sheet portion has a fourth lower end portion that forms the bottom end when configured as a file. and a fourth lower end portion that forms the lower end when configured as a file. The first sheet portion has a margin for adhering to the fourth sheet portion when configured as a file. The first, second, third, and fourth sheet portions and the margin for adhering are composed of a single rectangular sheet, connecting the first spine portion to the fourth spine portion, connecting the second spine portion to the third spine portion, and connecting the third lower end portion to the fourth lower end portion, with a gap portion between the margin for adhering and the second sheet portion. When viewed from the front of the single rectangular sheet, the second sheet portion is positioned below the first sheet portion, and the margin for adhering is positioned between the first and second sheet portions. The margin for adhering is connected to the first lower end portion, and extends beyond the fourth lower end portion to be adhered to the fourth sheet portion when configured as a file.

Furthermore, the file creation sheet of the second aspect is the same as that of the first aspect, in that, when viewed from the front of a single rectangular sheet, the height of the second sheet portion is smaller than the height of the first sheet portion.

Furthermore, a file creation sheet according to a third aspect is the same as that according to the first or second aspect, wherein the first sheet portion has a first edge portion that forms the edge when configured as a file, the second sheet portion has a second edge portion that forms the edge when configured as a file, and the third sheet portion has a third edge portion that forms the edge when configured as a file, and the first edge portion has a first index portion that serves as an index that becomes a heading, the second edge portion has a second index portion that serves as an index that becomes a heading, and the third edge portion has a third index portion that serves as an index that becomes a heading.

Furthermore, the file of the fourth aspect uses the file creation sheets of the first and third aspects, makes a valley fold at the connected third and fourth bottom ends, folds the second and third sheet parts so that they overlap the first and fourth sheet parts, and valley folds the connected first and fourth spines and the connected second and third spines, respectively, with the overlap portion extending beyond the fourth bottom end and glued to the fourth sheet part.

Because the present invention is constructed and operates as described above, it is possible to provide a file-making sheet that can be constructed from a single sheet without waste, and a file that is made using this file-making sheet without the need for heat welding.

1A is a front view of the file of this embodiment, and FIG. 1B is a back view of the file of this embodiment. FIG. 10 is a state diagram of a file in an open state according to the present embodiment. FIG. 1 is a front view of a rectangular sheet and a file creation sheet formed by processing the sheet. FIG. 10 is a reference perspective view illustrating a state in which a file is created by valley-folding a file creation sheet. FIG. 10 is a reference perspective view illustrating how the file creation sheet is further valley-folded to create a file.

This example will be described below with reference to the illustrated embodiment. The file 10 of this example is constructed by processing a single rectangular sheet 100 to create a file creation sheet 200 used for creating files, and then folding the file creation sheet 200 multiple times and gluing it together as described below. It is also possible to print on the sheet 100 in advance, and by doing so, it is possible to identify each sheet portion as described below.

The file creation sheet 200 is formed by, for example, punching out a single rectangular sheet 100. When the file creation sheet 200 is formed into the file 10, it has a first sheet portion 210 that forms the front surface, a second sheet portion 220 that forms a divider, a third sheet portion 230 that also forms a divider, and a fourth sheet portion 240 that forms the back surface.

Furthermore, the first sheet portion 210, which forms the front surface, has an overlap portion 300 that serves as an adhesive for attaching to the fourth sheet portion 240, which forms the back surface, as described below, when the file creation sheet 200 is configured into the file 10. This overlap portion 300 is located inside the file creation sheet 200. This will be described further below.

The first sheet portion 210, second sheet portion 220, third sheet portion 230, and fourth sheet portion 240 divide the file creation sheet 200 into approximately four sections, but the second sheet portion 220 has a smaller area than the first sheet portion 210, third sheet portion 230, or fourth sheet portion 240. This is because the overlap portion 300 of the first sheet portion 210 of the file creation sheet 200 configured as described above is positioned so as to encroach on the second sheet portion 220, so to speak.

In this embodiment, when viewed from the front of a single rectangular sheet 100, the second sheet portion 220 is positioned below the first sheet portion 210, and the overlap portion 300 is positioned between the first sheet portion 210 and the second sheet portion 220. In this manner, the overlap portion 300 can be positioned inside the file creation sheet 200, i.e., between the first sheet portion 210 and the second sheet portion 220. Although not shown, the overlap portion 300 can also be positioned between the third sheet portion 230 and the fourth sheet portion 240. Therefore, the overlap portion 300 does not protrude outward from the file creation sheet 200, and the file creation sheet 200 remains inside the rectangular sheet 100. This allows, for example, when the file 10 is used to store documents of A4 size according to the JIS standard, if the single rectangular sheet 100 is made of paper and is a sheet of paper of the standard size, the standard size sheet can be used without waste.

Next, we will explain the first sheet section 210, second sheet section 220, third sheet section 230, and fourth sheet section 240 of the file creation sheet 200. Because the file 10 has a structure similar to that of a book, the names of the parts that make up a book may be used. Note that the fore-edge sections, which will be described later, may be positioned to the right R when viewed from the front (see Figures 1 and 2).

The first sheet portion 210 is approximately rectangular in shape, and when configured into the file 10, has a first edge portion 211 that forms the so-called edge, a first spine portion 212 that forms the so-called spine, a first upper edge portion 213 that forms the top edge, and a first lower edge portion 214 that forms the bottom edge. The above-mentioned overlap portion 300 is connected to the first lower edge portion 214. The first height 215 is defined between the first upper edge portion 213 and the first lower edge portion 214. The approximately rectangular shape is due to the rounded corners.

The first edge 211, which forms the edge when configured as a file 10, has a first index section 211a that serves as a heading. The first index section 211a is formed by removing a portion of the first edge 211. There is also a first width H1 between the first edge 211 and the first spine 212.

The second sheet portion 220 is substantially rectangular in shape, and when configured into the file 10, has a second edge portion 221 that forms the edge, a second spine portion 222 that forms the spine, a second upper edge portion 223 that forms the top edge, and a second lower edge portion 224 that forms the bottom edge. It also has a second height 225 between the second upper edge portion 223 and the second lower edge portion 224. A gap 400 is provided between the overlap portion 300 on the first sheet portion 210 and the second sheet portion 220. In other words, in the file creation sheet 200, the first sheet portion 210 and the second sheet portion 220 are spaced apart by the gap 400. The substantially rectangular shape is due to the rounded corners.

The second edge 221, which forms the edge when configured as a file 10, has a second index section 221a that serves as a heading. The second index section 221a is formed by removing a portion of the second edge 221. There is also a second width H2 between the second edge 221 and the second spine 222.

The third sheet portion 230 is generally rectangular in shape, and when configured into the file 10, has a third edge portion 231 that forms the edge, a third spine portion 232 that forms the spine, a third upper edge portion 233 that forms the top edge, and a third lower edge portion 234 that forms the bottom edge. It also has a third height 235 between the third upper edge portion 233 and the third lower edge portion 234. It is generally rectangular in shape because it has rounded corners.

The third edge 231, which forms the edge when configured as a file 10, has a third index section 231a that serves as a heading. The third index section 231a is formed by removing a portion of the third edge 231. There is also a third width H3 between the third edge 231 and the third spine 232.

The first index section 211a, the second index section 221a, and the third index section 231a have different heights so that they can be visually identified when configured as file 10.

Fourth sheet portion 240 is generally rectangular in shape, and when configured into file 10, has a fourth edge portion 241 that forms the so-called edge, a fourth spine portion 242 that forms the spine, a fourth upper edge portion 243 that forms the top edge, and a fourth lower edge portion 244 that forms the bottom edge. It also has a fourth height 245 between fourth upper edge portion 243 and fourth lower edge portion 244. It is generally rectangular in shape because it has rounded corners. It also has a fourth width H4 between fourth edge portion 241 and fourth spine portion 242.

As described above, the file creation sheet 200 has a first sheet portion 210, a second sheet portion 220, a third sheet portion 230, and a fourth sheet portion 240. Specifically, the file creation sheet 200 is configured by connecting the first spine 212 of the first sheet portion 210 to the fourth spine 242 of the fourth sheet portion 240, connecting the second spine 222 of the second sheet portion 220 to the third spine 232 of the third sheet portion 230, and connecting the third bottom end 234 of the third sheet portion 230 to the fourth bottom end 244 of the fourth sheet portion 240.

Furthermore, it is preferable that the first width H1 and the fourth width H4 are approximately the same, and that the second width H2 and the third width H3 are approximately the same. In this case, it is preferable that the second width H2 is smaller than the first width H1. Therefore, when the fourth edge 241 and the third edge 231 are arranged in a straight line on the file creation sheet 200, the positions of the fourth spine 242 and the third spine 232 are slightly offset to the right R when viewed from the front (see Figure 3). This is because the thickness of the sheet 200 must be taken into consideration when creating the file 10.

Furthermore, while the first height 215, third height 235, and fourth height 245 are all approximately the same height (dimension), the second height 225 is smaller (shorter) than these heights. In other words, in the file creation sheet 200, the second sheet portion 220 is eroded by at least the amount of the overlap portion 300 and gap portion 400 located on the first sheet portion 210.

As described above, the overlap portion 300 is located inside the file creation sheet 200, and therefore the overlap portion 300 does not protrude outside the file creation sheet 200. This means that a single rectangular sheet 100 of standard size can be processed to create the file creation sheet 200 used for creating files. This allows sheets of paper, such as thick paper or cardboard, to be used without waste. Note that the overlap portion 300 is located inside the file creation sheet 200 and does not protrude outside the file creation sheet 200 means that the overlap portion 300 is not located at the first edge 211, second edge 221, second top edge 223, third top edge 233, third edge 231, fourth edge 211, fourth top edge 243, and first top edge 213, which form the outer periphery of the file creation sheet 200 in a counterclockwise direction in FIG. 3, but is located at the first bottom edge 214 inside the file creation sheet 200.

Next, the file 10 is created using the file creation sheet 200. The third lower end 234 and fourth lower end 244 of the file creation sheet 200, which are connected to each other, are valley-folded. This folds the second sheet portion 220 and third sheet portion 230 so that they overlap the first sheet portion 210 and fourth sheet portion 240.

Then, the second spine 222 and the third spine 232, and the first spine 212 and the fourth spine 242 are each valley-folded. The file 10 can then be created by adhering the overlapping portion 300 to the fourth sheet portion 240 with an adhesive beyond the fourth bottom edge 244. As described above, the file 10 can be created by adhering the overlapping portion 300 to the fourth sheet portion 240, thereby avoiding problems such as cracking of the heat-welded portion, which occurs with files created by heat-welding synthetic resin sheets. Furthermore, by locating the overlapping portion 300 inside the file-creation sheet 200, if the single rectangular sheet 100 is made of paper and is a sheet of paper, sheets of paper of the specified dimensions can be used without waste. The same applies when a synthetic resin sheet is used.
