Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a loose-leaf file capable of binding paper sheets to an internal binder.

[Conventional technology]

Conventionally, in a loose-leaf file that is configured by mounting a binder on the inner surface side of the shoulder cover that is between the front cover and the back cover, in general, the front cover and the back cover are bent at substantially right angles from both sides of the shoulder cover. It was structured so that it could be bent freely.

[Problems to be solved by the device]

Therefore, both sides of the shoulder cover are angular and easily damaged,
Moreover, it is difficult to carry when carrying it, and the shoulder cover must be wide when a large binder is attached to increase the capacity, and therefore the shoulder cover must be reinforced. It had a problem that it became a complicated structure and cost increased.

[Means for Solving the Problems]

The present invention solves such problems and enhances the product value by giving a high-class feeling, so that the width of the shoulder cover is not wider than the diameter of each nail of the binder. The inner groove and the outer groove extending in the entire longitudinal direction between the both sides of the shoulder cover and the front cover and the back cover and corresponding to the inside and the outside, respectively, at least at regular intervals on the inner surface and the outer surface, respectively. Engrave three or more,
The whole is made of polypropylene so that it bends from each groove and bends greatly between both sides of the shoulder cover and the front and back covers.

[Action]

Therefore, both sides of the shoulder cover can be greatly curved by the inner and outer grooves to give a bulge, which gives a high-grade appearance and is comfortable to carry and easy to carry. The shoulder cover side is not damaged, and even if the shoulder cover is narrow, a large-capacity file can be attached by directly attaching a large binder without reinforcement.

〔Example〕

Next, an embodiment shown in the drawings will be described. Made of polypropylene that has the same thickness as a whole, and extends between the both sides of the shoulder cover (3) and the front cover (1) and the back cover (2) to extend in the entire lengthwise direction to accommodate inner and outer grooves. The inner groove (5) and the outer groove (6) are formed on the inner surface and the outer surface at regular intervals by four pieces each, and the inner groove (5) is formed to be slightly wider than the outer groove (6). When bent from the respective grooves (5) and (6), the sides of the shoulder cover (3) and the front cover (1) and the back cover (2) are largely bulged and curved.

On the inner surface side of the shoulder cover (3), a binder (A) having each ring-shaped claw (4) having a diameter (D) slightly longer than the lateral width (W) of the shoulder cover (3) is used as a stopper. (8) The side edges (7a) and (7b) of the transparent and resinous wide heading cover (7) attached by (8) are attached to the outer groove (6) of the front cover (1) and the back cover (2). ) The head cover (7) is welded to the respective end portions so that a head piece (not shown) having substantially the same size as the cover (7) can be inserted inside the head cover (7).

Therefore, when the file is closed, the inner and outer grooves (5) are formed on both sides of the shoulder cover (3) as shown in FIGS. 1 and 6.
By (6), it becomes possible to make it bulge by bending it greatly, and the shoulder cover (3) by that bulge.
The lateral width on the side is wide as indicated by L, so that the binder (A) having a large inner diameter can be covered.

Further, since the wide heading covers (7) are attached to the curved curved surfaces on both sides of the shoulder cover (3), it is possible to insert a wide heading piece in which large characters are written, and the shoulder cover (3) The heading can be surely and easily seen even when viewed obliquely from the front.

[Effect of device]

Thus, according to the present invention, both sides of the shoulder cover (3) can be greatly curved by the inner and outer grooves (5) and (6) so as to have a bulge, which gives a high-class appearance. What you can do is to increase the product value, moreover, it feels good and is easy to carry, and you don't mess with the shoulder cover (3) side, and you do not have to reinforce the shoulder cover (3). Even if it is narrow,
It will be possible to attach a large binder (A) to make a large-capacity file, and to open and close the front cover (1) and back cover (2) smoothly. It has the feature that it can be manufactured easily and can be preferably implemented.
