Description

[Detailed Description of the Invention] The present invention relates to a cover for a file, etc., which is formed by pasting a thin sheet such as a vinyl sheet or a leather sheet on the outer surface of a core material.

Conventionally, with this type of cover, the inner bag provided on the inner surface of the core material gave a feeling of hardness in use, and the inner bag was separated from the process of attaching the thin sheet to the outer surface of the core material. Since the inner bag was formed in a separate process, there was a waste of processing steps in forming the inner bag, and there were also problems with strength and aesthetics at both end edges.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to prevent the inner bag from feeling hard during use, and to eliminate waste in the processing process when forming the inner bag. The present invention aims to provide a cover for a file, etc., which can solve problems in terms of strength and aesthetics at both end portions.

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

In the cover of the present invention, a core material 1 made of cardboard or the like is provided over the entire cover, and a thin sheet 2 such as a vinyl sheet or a leather sheet is pasted on the outer surface 1b of this core material 1.
This thin sheet 2 is bent toward the inner surface 1a side of the core material 1 at both ends 1c, 1c of the core material 1 to form inner bags 2a, 2b, and inner pouch portions 2a, 2b of the thin sheet 2. At least the top and bottom edges 2a', 2a of the outer surface 2C
, 2 b', 2 b'' and 2C', 2c'' in the core material 1.
It is made by sandwiching and sewing three or four seams.

To explain this in detail, the core material 1 is made of a material with suitable strength and thickness such as cardboard, and has a top-to-bottom width and a horizontal width that span the entire front and back covers, and the center part of the width is As shown by the two-dot chain line in FIG. 3, bending grooves 5, 5 are formed in the vertical direction to form the back portion 1d by being bent.

A thin sheet 2 made of a soft material such as a vinyl sheet or a leather sheet and made as thin as possible to withstand strength is adhered to the entire outer surface 1b of the core material 1 with a suitable adhesive.

The thin sheet 2 has a top-to-bottom width that matches the top-to-bottom width of the core material 1, and a lateral width that is larger than the lateral width of the core material 1 by a predetermined dimension.

As a result, the thin sheet 2 stuck to the outer surface 1b of the core material 1 is bent toward the inner surface 1a side of the core material 1 at both ends 1c and lc of the core material 1, so that the inner bag 2 is attached to the bent portion.
a, 2b are formed.

That is, the inner bag portions 2a, 2b and the outer surface portion 2 of the thin sheet 2
C means top and bottom edges 2 a', 2 a'', 2 b', 2
b'', 2C', and 2C'' are sewn together by sewing 3 and 4 by sandwiching the tiger core material 1 and sewing with a sewing machine, thereby forming inner bags 2a and 2b.

In this embodiment, an elongated hole 6a is formed in the inner bag 2a to provide an opening 6 for inserting a business card 7, etc., and a cut 8 extending in the width direction is formed in the inner bag 2b. This makes it easy to insert documents into the computer.

In addition, in this embodiment, the inner bag portions 2 a , 2 b and the outer surface portion 2 C of the thin sheet 2 are sewn by sandwiching the core material 1 and sewing with a sewing machine at both side ends 1 c and lc of the core material 1 . By doing so, the sewn parts 3.4, 9.10 are formed over the entire circumference of the cover, which is preferable in terms of design.

As explained above, in the present invention, a core material 1 made of cardboard or the like is provided over the entire cover, and thin sheets 2 attached to the outer surface 1b of the core material 1 are attached to both ends 1c of the core material 1,
lc to the inner surface 1a side of the core material 1, and insert the inner bag 2a.
, 2 b, and the inner bag portion 2 of the thin sheet 2
At least the top and bottom edges 2 of a, 2b and the outer surface portion 2C
a', 2 a", 2 b', 2 b" and 2C', 2C
By sandwiching the core material 1 and sewing 3 and 4, the inner bags 2a and 2b are formed of a soft and thin material made of the same material as the thin sheet 2 attached to the outer surface 1b of the core material 1. The inner bags 2 a , 2 b do not feel hard during use, and the inner bags 2 a , 2 b are made of the outer surface 1 of the core material 1 .
The inner bags 2a, 2b can be formed in a continuous series of steps following the process of attaching the thin sheet 2 to the inner bags 2a, 2b. Since the thin sheet 2 to be formed is bent at both side edges 1c and lc of the core material 1, the strength and aesthetic appearance at both side edges 1c and 1C can be improved.
