Description

  The present invention relates to a cardboard file suitable for binding a large amount of documents.

  In general, when binding a small amount of a document having a thickness of about 1 to 2 cm, a thin file called a flat file is often used. As shown in FIG. 6, the file main body 51 constituting this file forms a pair of a cover portion 52 and a back portion 53 by folding a paper board with a ruled line, and also forms a pair of the cover portion 52 and the back portion 53. A double-structure binding tool holding portion 54 is formed by folding between the two.

  The binding tool holding portion 54 of the file main body 51 is provided with two binding legs 56 made of flexible strip-shaped plastic and a rigid presser plate 57 made of plastic or metal as the binding tool 55. The presser plate 57 is provided with two holes and a slider 58.

  When using this file, the binding foot 56 is inserted into the two holes formed in the document, and further inserted into the two holes of the holding plate 57, and the slider 58 is slid to bind the binding foot 56. When the front end side portion of the paper is bent, the document is held in a bound state.

  However, when binding a large amount of documents having a thickness of 3 cm or more, the above-mentioned file is insufficient in holding strength of the document. Therefore, a pipe type file as shown in FIG. 7 is frequently used. The The file main body 61 constituting this file is composed of a mount in which laminated paper is covered with a resin film such as polypropylene, and a pair of cover portions 62 and a back portion 63 are formed by folding the mount with ruled lines. It is said that.

  A metal binding tool 64 is attached to the back part 63 of the file body 61. The binding tool 64 includes a hinge-shaped base member 65 fixed to the back part 63, and a holder member 66 attached to and detached from the hinge member. The base member 65 includes two outer pipes 67, and the holder member 66 includes two inner pipes 68.

  When using this file, the outer pipe 67 of the binding tool 64 is inserted into two holes formed in the document, the inner pipe 68 is inserted into the outer pipe 67, and then the hinge of the base member 65 is moved to move the base. When the heads of the member 65 and the holder member 66 are engaged with each other, the document is held in a bound state. Such a pipe-type file is described as a generally used file in Patent Document 1 below.

Japanese Patent No. 4332093 (paragraph [0055], FIG. 6)

  However, the above pipe-type files are heavy and difficult to handle, and there are problems that it is difficult to write characters on the surface of the file body, and that they must be disposed of as non-combustible materials when disposed. There is.

  In view of this, an object of the present invention is to make it light and easy to handle and easily dispose of, while having a strength capable of reliably holding a large amount of documents even when bound.

  In order to solve the above-mentioned problems, the present invention folds a file body in which a pair of cover parts are connected via a back part and a file in which a document is bound with a binding tool by folding the file body with a ruled line on a cardboard. Thus, a dual-structure binding tool holding portion in which a pair of holding plate portions are bonded together is provided between the back portion and the cover portions on both sides thereof. Further, the pair of cover parts of the file body has a double structure in which the outer cover part and the inner cover part are bonded together, and white corrugated cardboard is used only on the front side as the file body material.

  In the file according to this device, a cardboard having excellent strength is used as the material of the file body, and a double-structure binding tool holding part is formed between the back part and the cover part on both sides thereof, so a large amount of documents are bound. When carrying the document, the document is clamped by the binding tool holding portion, and the hole and the mounting portion for holding the binding tool are not torn, and the document can be reliably prevented from falling off.

  Moreover, it becomes light and easy to handle, and the cover part has a double structure, so that the corner of the cover part is difficult to bend and has excellent durability.

  In addition, since the top of the binding tool holding portion is rounded by bending the cardboard, the hand is not cut at the edge of the cardboard.

  Furthermore, since there is no need to reinforce with a resin film, characters can be easily written on the surface of the cover or back with a water-based sign pen or the like. , Cosmetics can be ensured.
