Description

The present invention relates to file pockets and files.

A file pocket that can be detachably attached to a file equipped with metal fittings such as a ring is known. A file pocket is known in which a binding portion that can be bound with a metal fitting such as a ring is provided on the inside and an opening is provided on the outside facing the binding portion. The file pocket with an opening on the outside like this has the advantage that it is easy to put in and take out documents because documents etc. are taken in and out horizontally instead of vertically, but the inserted documents are easy to fall off. There are challenges. On the other hand, Patent Documents 1 and 2 disclose a file pocket provided with a flap at the opening on the outside of the bag body in order to prevent the inserted document from falling off.
Further, Patent Document 3 discloses a file inserted between films in which folded flaps are stacked. In this file, since the flap is sandwiched between both films, it is difficult to open the flap, and even if the entire file is tilted, it is difficult for the document to fall off.

Japanese Unexamined Patent Publication No. 4-31148 Jitsukosho No. 53-34982 No. 60-175670

However, the file pockets of Patent Documents 1 and 2 are arranged on the outside of the bag when the opening of the bag is closed by the flap, and may not be able to sufficiently secure the holding power of documents and the like. .. In addition, when binding to a file or the like, there is a risk that the flap will open unexpectedly due to an external force or the like when the bound file pocket is turned over.
On the other hand, when the flap is inserted inside the bag body as in Patent Document 3, the tip of the flap is outside the upper and lower closed sides (upper and lower ends where both sheets are welded, etc.) of the closed bag body of both sheets. On the other hand, there is a possibility that the upper and lower closed sides of the bag may be cut (or peeled off) by abutting against each other so as to press from the inside to the outside. Further, when opening and closing the flap, the flap is rotated around the bent portion of the outer end of the opening of the bag, and the outer end of the opening of the bag is deformed, so that the upper and lower parts of the bag are moved up and down. The closed side may be cut from the outside. When such cutting (peeling) or the like occurs, the document or the like may be caught by the cut portion and the cut portion may be expanded, and finally the closed side of the bag may be opened. In this way, deterioration due to use has become a problem.
It is an object of the present invention to provide a highly durable and highly document-retaining file pocket.

The file pocket of the present invention is a file pocket in which one film and the other film are overlapped with each other, and has a rectangular bag body in which the outer side is open and the other three sides are closed. The opening has a binding portion provided on the inside of the bag body and a flap provided on the outer opening of the bag body, and the opening is such that one film is outside the other film. The protrusion is provided with an inclined portion that is inclined so that the outer end is shortened, and the flap is provided inward from the outer end of the protrusion. The inner tip of the flap is characterized by being inserted between both films.

The file pocket of the present invention has an opening of a bag having a protrusion in which one film projects outward with respect to the other film, and the protrusion has a short outer end. Since the inclined portion is formed, the opening of the bag body is not easily cut in the opening / closing operation of the flap, and the durability is high as a whole. In addition, the holding power of documents is high.
That is, in the flap opening / closing operation, the flap is rotated around the outer end of the protruding portion as the central axis, but the protruding portion is provided between the outer ends of the upper and lower closed sides of the bag body and the rotation axis of the flap. Will be. Therefore, when the flap is rotated, the influence on the outer edges of the upper and lower closed sides of the bag body can be minimized. Further, since the protruding portion is formed with an inclined portion that is inclined so that the outer end is shortened, even if the protruding portion is deformed together by rotating the flap, the inclined portion is deformed, and the bag The effect is less likely to affect the outer edges of the upper and lower closed sides of the body. Therefore, deterioration due to use is less likely to occur, and durability is high.
Further, in the file pocket of the present invention, when the inner tip of the flap is inserted into both sheets, the inside and the outside of the pocket are communicated with each other by the inclined portion of the protruding portion. Therefore, even if the pressure inside the pocket is applied by inserting a document or the like, air is discharged from the inclined portion of the protruding portion, and it is difficult for the flap to open. Therefore, the holding power of documents is even higher.

It is preferable that the file pocket of the present invention has an angle of the inclined portion of the protruding portion of 30 degrees or more and 70 degrees or less with respect to the vertical direction. If the internal angle of the isosceles trapezoid of the protrusion is smaller than 30 degrees, the flap becomes small and the holding power of the document may decrease. This is the case when the internal angle of the isosceles trapezoid of the protrusion is larger than 70 degrees. In particular, 50 degrees is preferable.
It is preferable that the file pocket of the present invention has a width of the protruding portion in the inward and outward directions of 3 mm or more and 10 mm or less. If the width of the protruding portion is smaller than 3 mm, the upper and lower outer ends of the bag body are likely to be torn when the flap is opened and closed. If the width of the protrusion is larger than 10 mm, the holding power of the document may decrease. Is.
It is preferable that the file pocket of the present invention has an isosceles trapezoidal shape of the protruding portion.

The file pocket of the present invention preferably has a flap having a width of 3 cm or more and 5 cm or less in the inner and outer directions. If the width of the flap is smaller than 3 cm, the area of the portion of the flap to be inserted into both films becomes small, and the holding power of the document decreases. If the width of the flap is larger than 5 cm, inserting the flap between the films, that is, closing the flap becomes complicated.
The file pocket of the present invention preferably has an isosceles trapezoidal shape in which the inner tip is shorter than the outer base end. Since the inner tip of the flap is shortened, it becomes difficult for the inner tip of the flap to come into contact with the outside of the upper and lower closed sides of the bag body in the opening / closing operation of the flap. In that case, it is preferable that the internal angle of the outer base end of the isosceles trapezoid of the flap is 30 degrees or more and 70 degrees or less. When the internal angle of the outer base end of the isosceles trapezoid of the flap is smaller than 30 degrees, the area of the portion inserted into both films of the flap becomes small, and the holding power of the document decreases. If the internal angle of the outer base end of the isosceles trapezoid of the flap is larger than 70 degrees, the inner tip of the flap may come into contact with the flap when the flap is opened or closed. Especially, 50 degrees is preferable.
It is preferable that the file pocket of the present invention has an equal inner angle between the inner angle of the inner end of the isosceles trapezoid of the protrusion and the inner angle of the outer base end of the isosceles trapezoid of the flap.

It is preferable that the file pocket of the present invention is provided with a welded portion in which the one film and the other film are linearly welded between the bag body and the bound portion. In this case, when the document or the like is inserted, the document or the like does not reach the binding portion. Therefore, the documents and the like do not come into contact with the metal fittings and the like of the file and are not damaged.
The file pocket of the present invention, wherein the film is a laminated film in which biaxially stretched polypropylene and unstretched polypropylene are laminated, and the unstretched polypropylene is laminated so as to face each other is preferable. Since biaxially stretched polypropylene has high transparency, the overall appearance can be improved by using the surface of the file pocket. On the other hand, since unstretched polypropylene has a small friction with paper, the back surface (inner surface) of the file pocket makes it easier to insert documents and the like.

The first aspect of the file of the present invention is characterized in that the file pocket of the present invention is detachably fixed.
A second aspect of the file of the present invention is a book-shaped file in which a plurality of pockets are combined, wherein the pocket is a stack of one film and the other film, and the outer side is open. It has a rectangular bag body in which the other three sides are closed, a joint portion provided inside the bag body, and a flap provided in an opening outside the bag body. The opening includes a protrusion in which one of the rectangular films projects outward with respect to the other rectangular film, and an inclined portion inclined so that the outer end is shortened is provided above and below the protrusion. The flap is formed and is characterized in that the flap is provided inward from the outer end of the protrusion, and the inner tip of the flap is inserted between both films. In particular, it is preferable that the shape of the protruding portion is an isosceles trapezoid in which the outer end is shorter than the inner end.

The file pocket of the present invention has high durability because the closed side of the bag is not easily cut even after repeated use. In addition, the holding power of documents is high while maintaining the ease of inserting documents.

FIG. 1a is a front view showing an embodiment of the film pocket of the present invention, and FIG. 1b is a partially enlarged view showing an outline of an X-ray cross section thereof. FIG. 2a is a partially enlarged view showing a protruding portion of the film pocket of FIG. 1, and FIG. 2b is a schematic view showing a state when the bag body is opened. It is a partially enlarged view which shows the flap of the film pocket of FIG. An example of using the film pocket of FIG. 1a is shown. 5a to 5c are partially enlarged views showing protrusions of other embodiments of the film pocket of the present invention, respectively.

The file pocket 1 of FIG. 1 is a stack of one film (back surface side in FIG. 1) 1a and the other film (front surface side in FIG. 1) 1b. Specifically, it has a rectangular bag body 10, a binding portion 20 provided inside the bag body 10, and a flap 30 provided at an opening 11d on the outside of the bag body 11.

The bag body 10 is provided with an opening 11d on the outside, and the inside (welded portion 11c) and the top and bottom (closed sides 11a, 11b) are closed. The upper and lower closed sides 11a and b and the welded portion 11c are closed by laminating both films 1a and 1b and welding on them. The inside of the welded portion 11c of the bag body 11 is a binding portion 20. By welding the welded portion 11c, when the document or the like is inserted, the document or the like does not reach the binding portion 20. Therefore, the documents and the like do not come into contact with the metal fittings and the like of the file and are not damaged.
The outer opening 11d of the bag 11 includes a protrusion 15 in which one film (back side in FIG. 1) 1a is projected outward with respect to the other film (front side in FIG. 1) 1b.

As shown in FIG. 2a, the protruding portion 15 has an isosceles trapezoidal shape in which the outer side 15a is shorter than the inner side 15b. That is, the upper and lower sides (inclined portions) 15c and 15d of the protruding portion 15 are inclined.
Since the upper and lower sides 15c and 15d of the protruding portion 15 are inclined, as shown in FIG. 2b, when the flap 30 is opened, the protruding portion 15 is deformed to the back surface side, and the bag body 10 due to the deformation of the protruding portion 15 It is possible to reduce the force in the direction of separating both sheets directly applied to the upper and lower closed sides 11a and 11b (region A in FIG. 2a). Further, even if the flap 30 is closed, the bag body 10 and the outside are communicated with each other by the upper and lower sides 15c and 15d, so that the pressure is discharged to the outside even if pressure is applied to the bag body 10 when inserting a document or the like. , It is difficult to apply a force in the opening direction to the flap 30.

The internal angles θ1 of the upper and lower sides (inclined portions) 15c and 15d of the protruding portion 15 are 30 degrees or more and 70 degrees or less, preferably 30 degrees or more and 60 degrees or less, and more preferably 40 degrees or more and 55 degrees or less. , Particularly preferably 50 degrees. If the internal angle θ1 is smaller than 30 degrees, the flap becomes small and the holding power of the document may decrease. When the internal angle θ1 is larger than 70 degrees, for example, as described above, to the outer ends (region A in FIG. 2a) of the upper and lower closed sides 11a and b of the bag body 10 due to the deformation of the protruding portion 15 when the flap 30 is opened. The influence of is stronger.
The width d of the protrusion 15 in the inward and outward directions is 3 mm or more and 10 mm or less, preferably 4 mm or more and 7 mm or less, and particularly preferably 4.5 mm or more and 6 mm or less. When the width d of the protruding portion is smaller than 3 mm, the deformation of the protruding portion 15 due to the opening of the flap 30 has a strong influence on the outer ends (region A in FIG. 2a) of the upper and lower closed sides 11a and 11b of the bag body 10. .. If the width d of the protruding portion 15 is larger than 10 mm, the supporting force of the flap 30 by the protruding portion 15 may decrease, and as a result, the holding force of the document may decrease.

The binding portion 20 is a portion for binding to a file such as a ring file, and is provided with two binding holes 21. However, the number of binding holes can be appropriately selected according to the file format. The inner end of the binding portion 20 is a folded portion connecting one sheet 1b and the other sheet 1a.

As shown in FIGS. 1 and 3, the flap 30 is provided inward from the outer end 15a of the protrusion 15. The flap 30 is connected to the protruding portion 15 via a bent portion. The flap 30 has an isosceles trapezoidal shape in which the inner tip 31 is shorter than the outer base end (outer end 15a of the protruding portion) on the bent portion side. That is, the upper and lower ends 32a and b of the flap 30 are inclined. Then, the inner tip 31 of the flap 30 is inserted between both films 1a and 1b.
Since the flap 30 has an isosceles trapezoidal shape, there is little possibility that the inner tip 31 of the flap 30 comes into contact with the upper and lower closed sides 11a and 11b of the bag body 10 in the opening / closing operation of the flap 30. Further, the flap 30 can be easily inserted into the bag body 10.
Since the flap 30 is inserted in the bag body 10 (between both sheets 1a and 1b), the holding force of the document is improved by the frictional force between both sides of the flap 30 and the inner surfaces of both sheets 1a and 1b. ..

The internal angles θ2 of the upper and lower ends 32a and 32b of the flap 30 are 30 degrees or more and 70 degrees or less, preferably 30 degrees or more and 60 degrees or less, more preferably 40 degrees or more and 55 degrees or less, and particularly preferably 50 degrees. Degree. If the internal angle θ2 is smaller than 30 degrees, the flap 30 may become small and the holding power of the document may decrease. When the internal angle θ2 is larger than 70 degrees, when the flap 30 is pulled out from the bag body 10, the inner tip 31 of the flap tends to come into contact with the upper and lower closed sides 11a and 1b of the bag body 10 (region A in FIG. 2a). Become. It is particularly preferable that the internal angle θ2 of the flap 30 and the internal angle θ1 of the protruding portion 15 are the same.
The width d2 of the flap 30 in the inward and outward directions is 3 cm or more and 5 cm or less, preferably 3.5 cm or more and 4.5 cm or less. When the width d2 of the protruding portion is smaller than 3 cm, the area inserted between the two sheets is small, the frictional force with the inner surfaces of both sheets is small, and the holding force of the document is lowered. When the width d2 of the protruding portion is larger than 5 cm, it becomes complicated to insert the flap 30 between both sheets in the opening / closing operation of the flap 30.

Next, a method for manufacturing a file pocket will be described.
A laminated film in which biaxially stretched polypropylene and unstretched polypyrropyrene are laminated is prepared. The thickness of the laminated film is 20 μm to 60 μm. Next, one laminated film is folded so as to be longer by the width of the protrusion 15 and the width of the flap 30. That is, one film 1a and the other film 1b are formed by folding one laminated film, and the inner end of the binding portion 20 becomes a folded portion. At this time, the unstretched polypropylenes face each other. Since biaxially stretched polypropylene has high transparency, the overall appearance can be improved by using the surface of the file pocket. On the other hand, since unstretched polypropylene has a small friction with paper, the back surface (inner surface) of the file pocket makes it easier to insert documents and the like.
After folding both films in this way, the upper and lower ends 11a and 11b of the bag body 10 and the inner ends 11c are welded, and one film 1a is folded back to form a flap 30, and the upper and lower sides 15c and 15d of the protruding portion 15 are formed. The film pocket 1 is manufactured by cutting the upper and lower ends 32a and 32b of the flap 30. The order of the steps after folding both films is not particularly limited. Further, although the inner end of the binding portion 20 is used as a folded portion here, any of the upper and lower closed sides 11a and 11b of the bag body 10 may be used as a folded portion, or the three sides of both independent films may be welded. good.

The file pocket 1 configured in this way is provided with an isosceles trapezoidal protrusion 15 and an isosceles trapezoidal flap 30, so that the upper and lower closed sides of the bag 10 can be used depending on the use. There is little risk that 11a and 11b will be torn and opened. Further, since the flap 30 is inserted into the bag body 10, the holding power of the document is high. Then, even if pressure is applied to the inside of the bag body 10 when inserting a document or the like, air is discharged from the protruding portion 15, so that the flap 30 is difficult to open.
Further, as shown in FIG. 4, the file pocket 1 does not fall even if it is hooked so as to be supported by a bent portion between the flap 30 and the protruding portion 15 in a state where a document or the like is inserted. In particular, since the string P can be passed through the inclined portions 15a and 15b of the protruding portion 15, it is possible to prevent the file pocket 1 from being deteriorated by the string P.
The file pocket of FIG. 1 is intended for a replaceable file such as a ring file, but may be used for a book-type file in which a plurality of file pockets are fixed. In this case, the binding portion 20 is different from the file pocket 1 of FIG.

The file pocket of the present invention is not limited to the above embodiment.
For example, in the file pocket 1A of FIG. 5a, the protruding portion 40 is composed of a rectangular portion 41 having the same length on the inside and the outside, and an isosceles trapezoidal portion 42 provided on the outside thereof. Also in this case, inclined portions are formed at the upper and lower ends 42a and 42b of the isosceles trapezoidal portion of the protruding portion. Further, in the file pocket 1B of FIG. 5b, the protruding portion 40A may be composed of an inner isosceles trapezoidal portion 42 and a rectangular portion 41 provided on the outer side thereof. In these cases, as shown in FIG. 2b, since the opening 11d of the bag body 10 is opened, even if the protruding portion 15 is deformed to the back surface side, the isosceles trapezoidal portion is deformed first, so that the bag body is deformed first. The influence on the outer ends (region A in FIG. 2a) of the upper and lower closed sides 11a and 11b of 10 can be reduced.
An inclined portion may be provided only on the upper end 15c (or only the lower end) of the protruding portion 15 as in the file pocket 1C of FIG. 4c. Further, the internal angles θ of the upper and lower ends 15c of the protrusions 15 may be different (not shown). However, it is preferable that inclined portions inclined at the same angle are provided above and below the protruding portion 15.
