BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filing article for storing sheets such as documents, and more specifically, a filing cover for a filing article, that is, a front cover and a back cover are continuously provided on both sides of a back. The present invention relates to an improvement of a filing cover in which a sheet-like binding device such as a document is attached to an inner surface of a back. The invention also relates to a filing article using the filing cover.

[0002]

2. Description of the Related Art Conventionally, such a filing cover is
Normally, a front cover and a back cover are directly provided on both sides of the back via thin hinge portions, and an openable ring-shaped binding tool or the like is attached to the inner surface of the back to be used as a filing product.

[0003]

By the way, such a filing article protrudes from the upper surface of a sheet-like material such as a document stored by a binding device in a double-page spread state.
When writing is attempted in the filing state, the protruding binding tool comes into contact with the hand and writing is difficult. Therefore, it was not suitable for binding books and the like. In addition, in the double-page spread state, the whole of the binding device is clearly exposed, so there is a problem in appearance,
In addition, because the spread document is curved without being flat,
There was also a difficulty that it was hard to see.

Therefore, the purpose of this invention is to
The bindings do not protrude significantly from the top of the filed sheet, so writing is easy, the bindings are not exposed explicitly and the appearance is excellent, and the stored documents can be opened. It is an object of the present invention to provide a filing cover which can be formed as a filing article which is in a flat state as much as possible and which is easy to see. It is another object of the present invention to provide a filing article using such a filing cover.

[0005]

In order to achieve the above-mentioned object, in this invention, a front cover and a back cover are erected on both sides of the back in an upright state, and a thin hinge portion for opening and closing the cover and the back cover is provided near the fore edge. With this arrangement, when the binding device is attached to the inner surface of the back portion, the height of the thin hinge portion is substantially equal to or less than the height of the thin hinge portion.

That is, in the filing cover according to the present invention, in a filing cover in which a front cover and a back cover are continuously provided on both sides of a back, a front cover and a back cover having a thin hinge portion for opening and closing are provided on the back. It is characterized in that it is connected in an upright state, and as a configuration in which a front cover and a back cover are connected in an upright state on both sides of a back portion, means for providing a substantially V-shaped groove in the connecting portion is adopted. I have. That is, in a filing cover in which a front cover and a back cover are continuously provided on both sides of the back, the front cover and the back cover are joined to the substantially V-shaped groove walls provided at a portion connected to the back and stand up against the back. The filing cover is provided in an installed state, and is provided with a thin hinge portion that enables opening and closing of the front cover and the back cover at a position slightly closer to the fore edge from the continuous portion.

[0007] Such a filing cover can easily change the structure of the back by changing the opening angle of the substantially V-shaped groove. For example, when the substantially V-shaped groove has a right-angled opening angle, the back portion is configured in a square box shape. If the opening angle is an obtuse angle, the trapezoidal box is formed as a planar shape, and if the opening angle is an acute angle, the trapezoidal box is formed.

As a structure in which the front cover and the back cover are connected to each other on both sides of the back portion in an upright state, a means using a thin hinge portion and a spacer can be further employed. That is, in a filing cover with a front cover and a back cover on both sides of the back,
The front cover and the back cover are provided in an upright state by being bent at a thin hinge portion provided at a portion connected to the back, and the upright state is held by spacers interposed and bonded at the upper and lower ends of the back. A filing cover provided with a thin hinge portion that allows the front and back covers to be opened and closed at a position slightly closer to the fore edge from the continuous portion. As such a spacer, a block of a non-staining soft polyurethane elastomer having persistently high tackiness at normal temperature can be used. If a document binding tool having a height substantially equal to or less than the position of the thin hinge portion is attached to the inner surface of the back of such a filing cover, a filing product that can easily write on a sheet-like material such as a recorded document can be provided. .

[0009]

As described above, in the case of a filing cover in which the front cover and the back cover having the thin hinge portion for opening and closing near the back and the back cover are connected to the back in an upright state, the binding device is attached to the inner surface of the back. If you configure filing supplies with
It can be a filing product that can be easily written, etc.Because a box-shaped part is formed by the part from the hinge part of the front cover and back cover to the continuous part with the back and the back part, the structure near the back part is firm, A stable self-standing state can be obtained when stored in an upright state on a bookcase or the like.

If a substantially V-shaped groove is provided in a portion connected to the back and the groove wall is joined, the structure of the back can be changed by changing the opening angle of the substantially V-shaped groove. For example, if the opening angle is set to an obtuse angle, the trapezoidal box can be formed in a planar shape. However, such a back structure makes it easier to hold the back portion and pull it out when stored in an upright state.

In the configuration in which spacers are interposed and bonded at the upper and lower ends of the back, the structure is solid and the standing state of the front cover and the back cover does not break even when the file is dropped.

When a document binding device having a height substantially equal to or less than the position of the thin hinge portion is attached to the inner surface of the back of the filing cover, when the documents, books and the like are stored and opened, the binding device is used. Can be easily written without being in the way. Further, the appearance of the binding device is improved because only the flat surface portion is exposed and the side surface portion is hidden. In addition, since the open state of the document or the like is as flat as possible, the document surface is easy to see.
