The surface side of the front sheet 30 is formed into a smooth surface 30A and the front side of the rear sheet 31 is formed into a satin surface and, by this constitution, even if a plurality of the housing bags 26 are superposed one upon another, the mating surfaces of them do not adhere mutually.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage bag and a file, and more particularly, to a storage bag and a file which are not adhered to each other when they are superimposed on one another, and maintain good visibility of a storage object. It relates to storage bags and files that can be stored.

[0002]

2. Description of the Related Art Heretofore, there has been known a pocket file in which a pocket formed of a resin sheet material in a bag shape can be bound to a predetermined binding tool. The pockets used for this file are made of polypropylene or other material with a light-transmitting property, so that documents, catalogs, etc. stored in the pockets can be viewed from the outside. Has become. Here, as a conventional pocket seat structure, a fine uneven surface, for example, a type subjected to a satin finish on the front and back surfaces of the sheet, and a smooth surface where the front and back surfaces of the sheet are “slippery” are formed. Types are known.

[0003]

However, when the front and back surfaces of the sheet are satin-finished, there is an inconvenience that the visibility of the documents stored in the pockets becomes less transparent. On the other hand, in the case where the front and back surfaces of the sheet are formed as smooth surfaces, reflection occurs due to gloss, and there is a disadvantage that it becomes very difficult to see a photograph or the like when stored. In addition, when a plurality of pockets are overlapped with each other, they tend to stick to each other at their mating surfaces, which causes an inconvenience that turning over a page when using this type of storage bag as a file is problematic. I do. To explain this in more detail, when the front and back surfaces of the sheet are smooth surfaces, when they are stacked,
The mating surfaces are substantially in a vacuum state and the mating surfaces are stuck together, which hinders page turning.

In a conventional pocket, the thickness of a sheet material forming the pocket is 0.04 mm to 0.07 mm.
And it is very thin,
When the number of documents to be stored is large, or when small articles having a three-dimensional three-dimensional shape are stored, there is a disadvantage that the outer peripheral edge of the pocket is torn.

[0005]

SUMMARY OF THE INVENTION The present invention has been devised in view of such inconvenience, and its object is to maintain good visibility of a storage object and to superimpose a plurality of storage bags. Even when bound, the mating surfaces of the storage bags do not stick to each other, the inner surfaces of the storage bags do not stick to each other, and even when storing thick objects or three-dimensional small items, An object of the present invention is to provide a storage bag and a file in which the outer peripheral edge is less likely to be torn.

[0006]

In order to achieve the above-mentioned object, the present invention relates to a light-transmitting storage bag capable of storing paper sheets or small articles between front and back sheets made of a soft resin sheet. In each of the front and back sheets, one surface is provided on a fine uneven surface and the other surface is provided on a smooth surface, and the front sheet has one of the fine uneven surface and the smooth surface on the surface side. The surface is exposed, and the back sheet is
The other surface of the fine uneven surface and the smooth surface is exposed on the surface side. With such a configuration, since only one of the front and back surfaces of the sheet is a fine uneven surface, it is possible to maintain better visibility as compared with a case where each of the front and back surfaces is a fine uneven surface. . Moreover,
Since the mating surface when a plurality of storage bags are stacked and the inner surface of the storage bag have a relationship between the fine uneven surface and the smooth surface, respectively, it is possible to avoid the above-described sticking that occurs when the smooth surfaces are used. it can.

The present invention also relates to a file having a cover body provided with a predetermined binding device and a light-transmitting storage bag provided so as to be bindable to the binding device, wherein the storage bag is formed of a soft resin. Each of these front and back sheets is provided with a fine uneven surface on one side and the other surface is provided on a smooth surface, and the front sheet has the fine uneven surface on its front side. One of the surface and the smooth surface is exposed, and the back sheet has a configuration in which the other of the fine uneven surface and the smooth surface is exposed on the surface side. In such a configuration, although a large number of storage bags are always in an overlapping state, the page turning becomes very easy due to the relationship of the mating surfaces described above.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the above-mentioned storage bag, the front and back sheets have a substantially rectangular shape in plan view, and are provided with sheet lids of different colors that allow one end of the sheet to be opened and closed. It is preferable to employ As a result, it is possible to prevent the object to be stored from falling off, and it is possible to clearly recognize the presence of the lid piece, and whether the lid piece is in a state where the opening is closed, that is, the lid piece is displayed. It is possible to reliably recognize whether or not the sheet is located on the front side of the sheet.

The front and back sheets may have a thickness of 0.1 mm to 0.35 mm. With such a thickness, the thickness becomes considerably thicker than that of the conventional pocket. Therefore, by heat sealing the front sheet and the back sheet, the outer peripheral strength can be kept strong, and the number of stored documents can be increased. In addition, even when the number of pieces is increased, or when small articles having a three-dimensional shape are stored, inconveniences such as tearing of the outer peripheral portion can be effectively improved.

[0010] In the present specification, a "soft" resin sheet is a soft sheet that can follow the shape of an object having a three-dimensional shape when the object has a three-dimensional shape in a storage bag using the same. It has a bulk, and when the object is taken out, it immediately returns to a planar shape, and the deformation habit tends to hardly remain as compared with a sheet such as a polypropylene sheet usually used for this kind. It means a resin sheet.
As the soft resin sheet, specifically, a commercially available product name “Povic-T clear” manufactured by Achilles Corporation can be suitably used. This soft resin sheet can be exemplified by a soft polyolefin film, which has an EVA layer in the center, a PP layer having a fine uneven surface on one surface, and a PP layer having a smooth surface on the other surface. Things. The term “smooth surface” is used as a synonym for the fine uneven surface, and is used for a surface that is disposed on a path for extruding a resin sheet and that is finished by a roller having extremely high surface smoothness.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view of a file according to this embodiment. In this figure, file 10
Is configured to include a cover body 11, a binding device 12 fixed to the inner surface side of the cover body 11, and a flat storage bag 14 bound to the binding device 12.

The cover body 11 includes a spine 20 forming an area to which the binding device 12 is fixed, and a front cover 21 and a back cover 22 arranged continuously on both sides of the spine 20 in the short width direction.
Consists of Further, the binding device 12 is not particularly limited, but in the present embodiment, a binding device of a type that can form a closed loop by combining two binding legs 24 having a semicircular arc shape is employed.

As shown in FIG. 2, the storage bag 14 comprises a bag body 26 having an opening 25 formed at one end, and a lid 27 capable of closing the opening 25. . The bag main body 26 and the lid piece 27 are formed using the above-mentioned “Povic-T Clear” sheet, and have a thickness of about 0.15 mm.

The bag body 26 is composed of a front sheet 30 and a back sheet 31 having a substantially rectangular shape in a plan view and having a light-transmitting property. By providing, it is formed in a bag shape.
Here, the back sheet 31 is integrally provided with an extension 33 projecting from the opening 25 and serving as a region for fixing the lid 27. The front surface side of the front sheet 30, that is, the upper surface side in FIG. 2B is a smooth surface 30A.
The inner surface side is formed as a matte surface 30B which is a fine uneven surface. The back sheet 31 has a matte surface 31B on the front surface side, that is, the lower surface side in FIG. 2, and has an inner surface formed as a smooth surface 31A. The fine uneven surface of the present invention is not limited to the matte surface, but may be any surface having a surface roughness that does not cause the above-mentioned sticking when adjusted to a smooth surface.

The cover piece 27 is not particularly limited, but a color different from that of the bag body 26, in this embodiment, a white piece is used. This lid piece 27 is connected to the opening 25.

As a result, the strength of the sealing portion can be increased, and inconveniences such as a tear in the outer periphery can be solved even when small articles having a three-dimensional shape are stored. By the way, in the case of the storage bag 26 according to the present embodiment, if the paper has a thickness about the same as a commercially available copy paper, about 50
Even a sheet having a thickness of about one sheet can be stored without any trouble.

In the above embodiment, the smooth surface 30A appears on the surface of the front sheet 30 and the matte surface 31B appears on the surface of the back sheet 31, but the present invention is not limited to this. , May be in the opposite relationship. It is also possible to employ a plurality of small front sheets for the back sheet 31 and heat seal the plurality of front sheets on three sides to provide a plurality of pockets each having an opening at one end.

[0020]

As described above, according to the present invention,
The surface side of the front sheet is provided on any one of the fine uneven surface and the smooth surface, and the surface side of the back sheet is provided on the other surface of the fine uneven surface and the smooth surface. Since only one of the front and back surfaces of the sheet is a fine uneven surface, it is possible to maintain better visibility as compared with a case where each of the front and back surfaces is a fine uneven surface. Moreover,
Since the mating surface when a plurality of storage bags are superimposed has a relationship between the fine uneven surface and the smooth surface, it is possible to avoid the sticking seen when the smooth surfaces are used together, which is an unprecedented superior effect. Can be provided.

Further, in the configuration in which one end side of the front and back sheets is provided as an opening and lids of different colors are provided so that the opening can be opened and closed, falling off of the object to be stored can be prevented and the existence of the lid is clear. It is possible to reliably recognize whether or not the cover piece is in a closed state located on the front side of the front sheet.

The thickness of the front and back sheets is 0.1 m.
m to 0.35 mm, the thickness is considerably larger than the thickness of a conventional pocket. Therefore, the outer peripheral strength can be kept strong by heat sealing the front sheet and the back sheet, and the number of stored documents. In addition, even when the number of pieces is increased, or when small articles having a three-dimensional shape are stored, inconveniences such as tearing of the outer peripheral portion can be effectively improved.
