Description

The present invention relates to a file in which a pocket member is welded or adhered to the front cover or back cover of a cover body to form a pocket between the cover body and the pocket member.

2. Description of the Related Art Files capable of binding paper sheets, such as paper documents, loose-leaf sheets used as inner sheets of notebooks, and refills for resin-made clear books (so-called clear pockets and clear holders) are well known.

In addition, a pocket is provided on either or both of the front and back covers so that other paper sheets can be sandwiched on the inside or outside of the front or back cover of such a file. In some cases, members are welded or glued together to provide pockets (see, for example, Patent Document 1).

A conventional pocket member is formed in a sheet form, for example, from a resin material, and the bottom and side edges of the pocket member are welded or adhered to each other in a state where the pocket member is superimposed on the front cover or the back cover.

The operation of inserting the paper sheet into the pocket in the vertical direction toward the bottom of the pocket is often carried out with the edge or corner of the paper sheet along the side of the pocket. However, the edges or corners of the paper sheets that are close to the welded or glued sides are pressed between the pocket member and the cover body, causing strong friction and causing the paper sheets to get caught during the insertion operation. Sometimes it feels like Similar problems can occur when the paper sheet is inserted laterally into the pocket and toward the sides of the pocket, where the edges or corners of the paper sheet close to the bottom of the pocket get caught. .

FIG. 3 is a schematic cross-sectional view schematically showing a cross section taken along line AA in FIG. 2, with the binding tool 2 omitted. FIG. 4 is an exploded perspective view of the file F of this embodiment. FIG. 5 is a plan view showing the pocket member 3 before being welded to the cover body 1. FIG. FIG. 6 is a diagram showing a state in which the folded portion 32 of the pocket member 3 is welded to the cover body 1. As shown in FIG. FIG. 7 is a diagram showing a state in which the pocket member 3 is welded to the cover body 1. As shown in FIG. FIG. 8 is a view showing one mode of inserting the paper sheet S into the pocket P, and FIG. 9 is a schematic sectional view corresponding to FIG. 3 when the paper sheet S is inserted into the pocket P in the same mode. be. In FIG. 3, the portion on the side 11a side outside the second hinge 15 of the front cover 11 is omitted. In addition, in FIGS. 3 and 9, the thicknesses of the pocket member 3 and the paper sheets S are exaggerated to make them easier to understand.

The action of each part when inserting the paper sheet S into the pocket P will be described below.

As shown in FIG. 8, the paper sheet S is placed in the pocket P while one side edge Sa or corner of the paper sheet S is aligned with the side edge of the pocket P, that is, the outer side edge 3a of the pocket member 3. When inserting from above, that is, from the side of the top edge 13c of the back cover 13, the portion near one side edge Sa of the paper sheet S is positioned between the pocket member main body 31 and the folded portion 32, as shown in FIG. will be distributed to

Here, as shown in FIG. 12, in the file f0 of the conventional configuration, the paper sheets S are inserted from above into the pocket member a3 while the edges Sa or corners of the paper sheets S are aligned with the side edges of the pocket aP. and the inner surface a13s of the back cover a13, the paper sheet S was felt to be caught during the insertion operation for the following reasons. That is, the vicinity of the welded portion aY between the pocket member a3 and the back cover a13 has a wedge-shaped inner circumference, and when the paper sheet S reaches this area, the paper sheet S is pushed by the pocket member a3 toward the back cover a13. As a result, the edges Sa or corners of the paper sheets S approaching the sides of the pocket aP (sides a3a of the pocket member a3) were felt to be caught. In FIG. 12, the thicknesses of the pocket member a3 and the paper sheets S are exaggerated to make them easier to understand.

On the other hand, in the present embodiment, as shown in FIG. 9, the portion along which one side edge Sa or corner of the paper sheet S should be placed, ie, the outer side 3a of the pocket member 3, is simply the pocket member 3. Only the sheet material forming the is folded back. Accordingly, in the vicinity of the outer side 3a of the pocket member 3, the pocket member main body 31 and the folded portion 32 are elastically biased in a direction in which they are separated from each other. Therefore, even if the paper sheets S enter the vicinity of the outer side edge 3a of the pocket member 3, the paper sheets S are not elastically urged by the pocket member 3 toward the back cover 13 side.

As described above, according to the present embodiment, the outer sides 3a of the pocket member 3 are folded back, and the folded portions 32 are welded to the cover body 1. The operation of moving the edge Sa or the corner of the paper sheet S along the outer side 3a of the pocket member 3 is smoothly performed without being elastically biased by the pocket member 3 toward the back cover 13 side. be able to. Moreover, since the bottom side 3b of the pocket member 3 is welded to the back cover 13 without being folded back, the inner periphery of the pocket member 3 near the bottom side 3b and the welded portion to the back cover 13 has a wedge shape. Since the paper sheets S reaching this portion are strongly pressed against the back cover 13 side by the pocket member 3, the paper sheets S are held by this portion so that such paper sheets S do not come off easily. be able to.

Further, the outer side edge 3a of the pocket member 3 is folded back and the folded portion 32 is welded to the cover body 1, and the bottom edge 3b of the pocket member 3 is welded to the back cover 13 without being folded back. In view of the fact that the paper sheets S are often inserted from above into the pocket formed by the pocket member 3, the effect that the inserted paper sheets S can be prevented from slipping out while being smoothly inserted is provided. You can get it on many occasions.

In this embodiment, the outer side 3a of the pocket member 3 is arranged along the outer side 13a of the back cover 13, and the bottom 3b of the pocket member 3 is along the bottom 13b of the back cover 13. Since the pocket P is arranged in such a way that the width and height of the back cover 13 are substantially equal to each other, the paper sheet S can be held in the pocket P.

In addition, in the present embodiment, a pocket P is formed between one surface of the cover body 1 and the pocket member 3, more specifically, between the inner surface 13s of the back cover 13 and the pocket member 3. Since the folding part 32 of 3 is welded to the inner surface 13s of the back cover 13, the entire pocket member 3 is arranged inside the back cover 13, and the appearance can be kept neat. When the paper sheets S are inserted into the pocket P, the effect that the paper sheets S are less likely to be caught can be obtained more preferably.

In this embodiment, the folded portion 32 of the pocket member 3 is welded to the back cover 13 at a plurality of locations, more specifically, at two welding locations Y, so that the width of the folded portion 32 is increased to some extent. Also, the pocket member 3 can be securely fixed to the back cover 13. - 特許庁By securing the width of the folded portion 32 to a certain extent or more, the edges Sa or corners of the paper sheets S are prevented from being caught by the folded end 32a when the paper sheets S are taken in and out of the pocket P.

In addition, this invention is not restricted to embodiment mentioned above.

For example, in the embodiment described above, the folded portion of the pocket member is welded to the inner surface of the back cover, but as another embodiment, the following is conceivable. In the file F2 according to this embodiment, as shown in FIG. 10, the back cover 13 is sandwiched between the folding portion 32 of the pocket member 3 and the pocket member main body 31, which is another portion. That is, the folded portion 32 of the pocket member 3 is welded to the outer surface 13 t of the back cover 13 . The other parts have the same configuration as that of the file F in the above-described embodiment, so they are given the same names and reference numerals, and their explanations are omitted.

In this embodiment, one side edge or corner of the paper sheet is placed along the side edge of the pocket P, that is, the outer side edge 3a of the pocket member 3. When the paper sheet is inserted from the side, the part near one side edge of the paper sheet is arranged between the pocket member main body 31 and the back cover 13 . In this case also, since the sheet material forming the pocket member 3 is simply folded back on the outer side 3a of the pocket member 3, paper sheets do not enter the vicinity of the outer side 3a of the pocket member 3. However, the paper sheets are not elastically urged by the pocket member 3 toward the back cover 13 side. Therefore, even with the configuration of this embodiment, it is possible to obtain the main effects of the embodiment described above with reference to FIGS.

In addition, in the above-described embodiment, the pocket member is welded to the cover body, but there is another method such as applying an adhesive to the pocket member or the cover body and bonding the pocket member and the cover body together. Of course, the pocket member may also be adhered to the cover body.

Furthermore, in the embodiment described above, the side edges of the pocket member are arranged along the side edges of the back cover and the bottom edge is arranged along the bottom edge of the back cover, but the pocket member can be placed anywhere on the back cover. may be distributed.

In addition, in the above-described embodiment, the pocket is formed only on the inner surface of the back cover, but the pocket is formed on either the outer surface of the back cover or the front cover, in other words, the outer surface of the back cover or the front cover. The pocket member may be welded or adhered to either or all of the inner surface of the cover and the outer surface of the front cover. Of course, pockets may be formed on any one or all of the outer surface of the back cover, the inner surface of the front cover, and the outer surface of the front cover instead of forming the pocket on the inner surface of the back cover. Even when pockets are formed on the outer surface of the back cover, the inner surface of the front cover, and the outer surface of the front cover, the side edges and bottom edges of the pocket members may be arranged at arbitrary locations.

Moreover, in the above-described embodiment, the side edges of the pocket member are folded back, the folded portions are welded (or adhered) to the cover body, and the bottom edge is welded (or adhered) to the cover body without being folded back. However, a mode is adopted in which the bottom side of the pocket member is folded back, the folded portion is welded (or adhered) to the cover body, and the side edges are welded (or adhered) to the cover body without being folded back. Of course you can. In the above-described embodiment, the folded portion is welded to the cover body at two locations along the side edge and the folded edge, but the location where the folded portion is welded or adhered to the cover body can be set arbitrarily. good. Furthermore, the folded portion may be welded or adhered to the cover body only at one position (for example, only the folded edge), or conversely, the folded portion may be welded or adhered to the cover body at three or more positions.

On the other hand, in the above-described embodiment, the outer sides of the pocket member are folded back, the folded portions are welded (or adhered) to the cover, and the bottom is welded (or adhered) to the cover without being folded back. , the inner sides and the top side are open, but both side sides 3a and 3e of the pocket member 3 are folded back, and the folded portion 32 is adhered to the cover body 1 as in the file F3 shown in FIG. In addition, it is of course possible to employ a configuration in which the bottom side 3b is welded to the cover body 1 without being folded back, and the top side is the open portion 3c. In the file F3 described above, the bonding point y is set at the site near the folded end 32a and the side edges 3a and 3e of both folded portions 32, but the position and number of bonding points may be set arbitrarily. Any method of adhesion may be used. Other portions of the file F3 have the same configuration as that of the file F in the above-described embodiment, so they are denoted by the same reference numerals and descriptions thereof are omitted.

Furthermore, the bottom and top sides of the pocket member are folded back, and the folded portions are welded (or adhered) to the cover body, while one side is welded (or adhered) to the cover body without being folded back, and the other side is welded (or adhered) to the cover body without being folded back. Of course, a configuration in which the sides are open may be adopted.

The binding tool is not limited to being provided on the back cover as in the above-described embodiment, and the binding tool may be provided at any position on the cover body, such as providing the binding tool on the back cover. Moreover, the present invention may of course be applied to a file that does not have a binder (for example, a file that has only a hole for inserting a string for binding paper sheets, etc.).

In addition, the present invention may of course be applied to a file in which the cover is arranged only on one side of the sheets bound in the file, that is, the file has only the back cover.

In addition, various modifications may be made without departing from the gist of the present invention.
