Abstract

(57) [Summary] [Structure] A synthetic resin sheet is bent and welded at the side edges to integrally form the one-opened storage portion 2,
Two or more of the accommodating portions 2 are joined and the adjacent upper side connecting portions 5 are connected by welding. [Effect] Since the side plate 20 that has to form a large number of folds as in the past is not used, it is possible to perform die cutting of the members that form the storage unit 2 with a small press machine, resulting in equipment costs. It will not be bulky. In addition, since it is not necessary to form a large number of folds on the side plate 20 as in the conventional case, it does not take time and effort to manufacture the members that form the storage unit 2, and the manufacturing cost is reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a document storage device called a document file for storing documents, certificates and the like.

[0002]

[Prior art]

 Conventionally, as this type of document storage device, there is one as shown in FIG. 7, for example. This document storage device has a partition plate 21 interposed between the troughs 20a, 20a of both side plates 20, 20 having a large number of folds, and is divided into a plurality of storage parts 2 as its main body. Make up one.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional document storage device, the more the number of storage portions 2 is increased, the more the number of pleats must be formed on the side plate 20, so that the side plate 20 must be long. This necessitates a large press machine for die-cutting the side plate 20, which causes a problem of increased equipment cost.

Further, the work of forming a large number of folds on the side surface plate 20 has a problem that it takes time and labor and the manufacturing cost becomes high.

Therefore, the present invention was made in order to solve the above-mentioned conventional problems, and by not using the side plate 20 as in the related art, it is assumed that a large press machine is not required for die cutting. The purpose is to provide a document storage device that does not require high equipment costs and is inexpensive to manufacture.

[0006]

[Means for Solving the Problems]

 Therefore, in the document storage device according to the present invention, one synthetic resin sheet is bent and the side edges are welded to integrally form the storage part 2 having one opening, and two or more storage parts 2 are joined together. It is assumed that the connecting portions 5 on the adjacent upper sides are connected by welding.

[0007] The storage unit 2 can be made up of one unit, or two units can be integrally provided in series. Further, the connection part 5 may be formed so as to rise on the upper side of the storage part 2. Further, the headline accommodating portion 8 may be provided above the accommodating portion 2.

[0008]

[Action]

 Since the document storage device according to the present invention has the above-described configuration, it does not use the side plate 20 that has to be provided with a large number of folds as in the conventional case. Can be done at.

Further, since it is not necessary to form a large number of folds on the side surface plate 20 as in the conventional case, it does not take time and effort to fabricate the members constituting the storage section 2.

[0010]

【Example】

 The configuration of the document storage device according to the present invention will be described below in detail with reference to the drawings shown as examples.

FIG. 1 is a development view showing an example of a storage unit 2 of a document storage device according to the present invention. In this storage part 2, a fold 3 is provided in the center of one synthetic resin sheet, and cutouts 4 are formed by notching the upper and lower sides of the fold 3 and connecting parts 5 are formed on both sides of the fold 3. A connecting portion 5 is also formed in the center of the. Further, a fold line 6 is provided at the center of each of the left and right halves of the synthetic resin sheet, and folds 7 and 7 are provided above and below the outer side of each fold line 6 as required.

As shown in FIG. 2, the accommodating portion 2 is formed into a single sheet by bending the fold lines 3, the fold lines 6, the folding lines 7, 7 and welding the folding lines 7, 7 or side edges. The synthetic resin sheet is used to integrally form the two storage portions 2 of which one side is open.

In the structure shown in FIG. 3, three housings 2 having the above-described structure are joined together, and adjacent upper side connecting parts 5 are connected by welding. A front surface plate 11 and a back surface plate 12 which are freely bendable are continuously provided in front and rear portions of a bottom surface plate 10, and a front plate 13 which is freely bendable is continuously connected to the back surface plate 12 to form a main body 1. The bottom part of the storage part 2 is opposed to the bottom plate 10 of the main body 1, and the outermost connecting part 5 of the storage part 2 is bonded to the front plate 11 and the back plate 12.

In this embodiment, the connecting portion 5 is formed so as to rise on the upper side of the storage portion 2, but may be formed on the upper side of the storage portion 2.

Further, when the connecting portion 5 is formed so as to rise on the upper side of the storage portion 2, the heading storage portion 8 is provided on the upper portion of the storage portion 2 by welding the lower sides of the rising portions. be able to. When the connecting part 5 is the upper side of the storage part 2, a separate heading storage part 8 may be provided on the upper side.

Next, FIG. 4 is a development view showing another example of the storage portion 2 of the document storage device according to the present invention. The storage portion 2 has a fold line 3 formed at the center of one synthetic resin sheet and a connection portion 5 formed at the center of both side edges. Further, folding backs 7, 7 are provided at the upper and lower ends of the left half of the synthetic resin sheet, if necessary.

As shown in FIG. 5, the accommodating portion 2 is made of a single synthetic resin sheet by bending the fold lines 3, the folding lines 7, 7, and welding the folding lines 7, 7 or side edges. On the other hand, the open storage part 2 is integrally configured.

In the structure shown in FIG. 6, six of the thus configured storage parts 2 are joined, and the connecting parts 5 on the adjacent upper sides are connected by welding. Similar to the above-described embodiment, a main body in which a front surface plate 11 and a back surface plate 12 which are foldable are connected in series to the front and rear portions of a bottom plate 10, and a front surface plate 13 which is foldable is connected in series to the back plate 12. The bottom part of the storage part 2 is opposed to the bottom plate 10 of the main body 1, and the outermost connection part 5 of the storage part 2 is bonded to the front plate 11 and the back plate 12.

The connecting part 5 and the headline accommodating part 8 are constructed in the same manner as in the above embodiment.

[0020]

[Effect of device]

 The document storage device according to the present invention is configured as described above, and does not use the side plate 20 that has to form a large number of folds as in the conventional case, and therefore, the document storage device of Die cutting can be done with a small press machine, resulting in less equipment cost.

Moreover, since it is not necessary to form a large number of folds on the side surface plate 20 as in the conventional case, it does not take time and effort to manufacture the members that form the storage portion 2, and the manufacturing cost is reduced.
