Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a file in which documents are stored in parallel pockets.

[0002]

[Prior Art]

 As shown in FIG. 6 and FIG. 7, the conventional file has a pair of cover sheets 2 and 2 facing each other that are freely bendable via a synthetic resin bottom sheet 1, and also has an upper edge of one cover sheet 2. A flexible lid sheet 3 is connected to the above, and two synthetic resin end sheets 4 are bent in a zigzag shape at the equally-spaced crease lines 5 parallel to the edges thereof to form the cover sheets 2 and 2 Both end edges of the end sheet 4 are heat-bonded to both side edges of the facing surface, and both side edges of each partition sheet 6 of synthetic resin are heat-welded 7 to the surface between the fold lines 5 of the end sheet 4.

[0003]

[Problems to be solved by the device]

 In the file as described above, the side edge of the partition sheet is heat-bonded (using a heat pressing plate) to the surface between the fold lines of the end sheet, and therefore the heat-bonding is performed manually. That is, first, the end sheet is supplied under the heating press plate, and the end sheet is positioned using a jig so that the lower edge surface of the heating press plate and the bonding edge of the end sheet are aligned.

Next, the side edges of the partition sheet are superposed on the edge sheet, and the edge of the partition sheet is aligned with the bonding line of the edge sheet using a jig.

Then, the heating push plate is lowered to thermally bond the side edges of the partition sheet to the end sheet.

[0006] Therefore, it takes a great deal of time to heat-bond and cannot be mass-produced, resulting in an increase in cost.

There is also a problem that defective products are generated unless the side edges of the partition sheet are heat-bonded in a uniform size with respect to the broken line and in parallel with the broken line.

Therefore, an object of the present invention is to provide a file in which the side edge of the partition sheet can be easily attached to the end sheet.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention forms a pair of facing cover sheets that are bendable and facing each other via a bottom sheet, and also uses two end sheets by equally spaced fold lines parallel to the edges. In a file formed by bending in a zigzag shape, fixing both end edges of the end sheet to both side edges of the facing surfaces of the both cover sheets, and further attaching both side edges of a plurality of partition sheets arranged in parallel to the end sheet. A slit is provided in the end sheet, and an engaging piece protruding from the side edge of the upper partition sheet is inserted and engaged in the slit.

[0010]

[Action]

 The side edges of the partition sheet are attached to the end sheets by engaging the engaging pieces protruding from the both side edges with the slits of the both end sheets facing each other and engaging them.

[0011]

【Example】

 An embodiment according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, the bottom sheet 11 is formed on both side edges thereof with the cover sheets 12, 12 facing each other which are bendable.

A flexible lid sheet 13 is connected to the upper edge of one cover sheet 12.

Reference numeral 14 denotes two end sheets bent in a zigzag shape by fold lines 15 that are parallel to the end edges, and both ends of the end sheet 14 are fixed to both side edges of the opposite cover sheets 12 and 12. There is.

Reference numeral 16 denotes a plurality of partition sheets arranged side by side with respect to the end sheet 14 and engaging pieces 17 projecting from both side edges of the partition sheet 16 are provided on a slit 18 provided on the end sheet 14. To penetrate and engage.

As shown in FIG. 2 and FIG. 3, the above-mentioned engagement piece 17 projects in an inverted L shape from above and below (not limited in number) both side edges of the partition sheet 16 and has upper and lower slits 18 of the end sheet 14. After the engaging piece 17 was inserted into and passed through, the partition sheet 16 was moved downward to prevent the engaging piece 17 from coming out of the slit 18, but instead of the inverted L shape, It may be possible to provide a harpoon-shaped (not shown) engagement piece having retaining protrusions in opposite directions, and force the engagement piece to pass through the slit to prevent the engagement piece from coming off from the slit.

In the case of the inverted L-shaped engaging piece 17, as shown in FIG. 4, two parallel cuts 19 are made upward from both corners of the upper edge of the slit 18 of the punching window, and the cuts are formed. When the tongue piece 20 is provided between 19 and 20, when the engaging piece 17 is inserted, the tongue piece 20 is pushed out as shown by the chain line in FIG. 4, and when the partition sheet 16 is moved downward after the engagement piece 17 is inserted, the pushing piece is released. The released tongue piece 20 returns and the upward movement of the partition sheet 16 can be stopped by the contact between the upper edge of the engagement piece 17 and the lower edge of the tongue piece 20.

The slits 18 are provided on the fold line 15 shown in FIGS. 2 and 3, and between the fold lines 15 located inside and outside the end sheet 14 as shown in FIG. 5 (close to the fold line 15). In some cases).

The bottom sheet 11, the cover sheet 12, the lid sheet 13, the edge sheet 14, and the partition sheet 16 include a synthetic resin sheet and a cardboard. In the case of a synthetic resin sheet, the edge sheet 14 is provided on the cover sheet 12. Is heat-bonded, and in the case of thick paper, it may be fixed with an adhesive.

Further, the partition sheet 16 is attached to the slit 18 of each of the fold lines 15 on the inner side through the engaging piece 17, but the attaching position, that is, the number of sheets is not limited.

[0021]

【effect】

 As described above, according to the file of the present invention, since the engaging piece is inserted into the slit and engaged, and the side edge of the partition sheet is engaged with the end sheet, remarkably troublesome heat bonding is unnecessary. become. Therefore, it is possible to eliminate the cost increase and the cause of the defective product.

Further, since the partition sheets can be removed, the width between the partition sheets can be freely adjusted.
