Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file with a guide for easily and neatly binding materials such as photographs, catalogs, pamphlets, and documents (hereinafter referred to as "materials") one by one. It is.

[0002]

2. Description of the Related Art The above-mentioned materials can be easily and easily manipulated.
As shown in FIG. 1, the file to be bound has a thickness of 0.08 to 0.18 mm on the inner surface of the back 2 of the file 1.
The release paper 4 on one side of a double-sided adhesive tape 5 with ordinary release paper (hereinafter referred to as release paper) 4 is peeled off and bonded, and a plurality of slits 6 are spaced apart in the longitudinal direction of the other release paper 4 on one side. And a plurality of thin long plate-shaped release paper pieces 7 are formed. Then, in order to bind the material, a large number of thin long plate-like release paper pieces 7 are peeled off from the double-sided adhesive tape 5, and one end surface of the material 3 is attached to the adhesive surface.

[0003] This type of file can be easily obtained by simply pressing the material 3 on the adhesive surface of the double-sided adhesive tape 5 from which the thin long plate-shaped release paper piece 7 has been peeled off.
Although there is an advantage that the material 3 can be stapled, since the adhesive surface of the double-sided adhesive tape 5 does not serve as a guide when the material 3 is stapled, the material 3 is stapled irregularly on the inner surface of the back portion 2 of the file 1. There was a major drawback of getting caught.

[0004] Further, since both the back portion 2 and the double-sided adhesive tape 5 have no elasticity, the spreadability of the material 3 is poor, and particularly, there is a disadvantage that the bound portion of the material 3 is difficult to see.
If the user tries to forcefully open the material 3 with poor spread, the bound portion of the material 3 is broken, and the material 3 is separated from the inner surface of the back portion 2 of the file 1 and has a disadvantage of falling off.

On the inner surface of the back portion 2 of the conventional file 1, a large number of thin long plate-shaped release papers (having a thickness of 0.08-0.
18 mm) The double-sided pressure-sensitive adhesive tape 5 with the piece 7 is adhered to, for example, one end in the longitudinal direction of the surface of the double-sided pressure-sensitive adhesive tape 5 of the many thin long plate-shaped release paper pieces 7 as in the present invention. It is also conceivable to use the strip-shaped release sheet 7 having a thin long plate at both ends as a material binding guide without peeling the strip 7 (adjacent to the cover of the file 1). The adhesive surface of the double-sided adhesive tape 5 that has been peeled off and exposed is used as the binding surface of the document 3).

However, the release paper 4 used in the above-mentioned conventional file has a thickness of 0.08 to 0.18 m.
m, which has a drawback that it is not a guide for binding the material 3 because the thickness is small and the step is small, and the material 3 is irregularly bound on the inner surface of the back portion 2 of the file 1. Does not change.

[0007] Further, there is a type in which the material is inserted into a file bound with a plastic bag. This type has good spreadability of the material, but it is troublesome to insert the material into the plastic bag. Since the bag is bulky, there is a problem in that the number of materials to be bound is reduced, and there is also a problem that the materials are difficult to see because the materials are viewed through a film.

[0008]

[Problems to be Solved by the Invention] The present invention is to improve the disadvantages and inconveniences of the above-mentioned conventional material binding file, and does not require any troublesome work such as punching the material or putting it in a bag. The main purpose is to simply and simply press the one end of the material along the material binding guide against the adhesive surface on the inner surface of the back of the file to quickly and neatly align the material with the file. It is another object of the present invention to improve the spread of the materials as necessary and to make it easier to see the materials in the bound portion.

[0009]

Next, two slits 6 are formed in the longitudinal direction of the long release sheet 4 of the double-sided adhesive tape 5 which is the adhesive surface.
Are engraved at intervals to form three thin long strip-shaped release paper pieces 7.
a, 7b, and 7c are formed, and of these three thin long strip-shaped release paper pieces, the long strip-shaped release paper pieces 7a and 7c at both ends in the longitudinal direction of the double-sided adhesive tape 5 are peeled. Then, as shown in FIG.
The long and thin plate-like paper pieces 10a and 10c of not less than mm are attached to form a material binding guide 11, and the long and long plate-like release paper piece 7b at the center portion is not peeled off.

As the long plate-shaped foam 8, the following (1)
A material having the physical properties of (3) is the most suitable material for pasting the material 3. (1) The thickness of the foam 8 is 1/6 to 1 times the back width. (2) The hardness of the foam 8 is 0.6 to 16.0 kg / 314.
cm2 (measured according to JIS K6401) (3) Foam 8 with elongation of 100 to 250% (JI
SK6301 "Measurement by the physical test method of rubber")

The thickness of the foam 8 is limited to 1/6 to 1 time of the back width because the thickness of the foam 8 is 1/6 of the back width.
When the thickness is less than 10 mm, the elasticity of the material is insufficient and the spread of the material becomes insufficient.
If the width exceeds one time, the presence of the foam 8 is conspicuous and impairs the appearance of the file 1.

The hardness of the foam 8 is 0.6 to 16.0 kg /
The reason for limiting to 314 cm 2 is that if the hardness of the foam 8 is less than 0.6, it becomes difficult to attach materials and the foam 8 has no physical strength as a support.
If the hardness of the foam 8 exceeds 16.0, the elasticity of the foam 8 becomes difficult,
This is because spreadability becomes worse.

The reason why the elongation of the foam 8 is limited to the range of 100 to 250% is that if the elongation of the foam 8 is less than 100%, the elasticity of the foam 8 is reduced, and the spread is deteriorated. If the elongation of the foam 8 exceeds 250%, the foam 8 is too soft, the physical strength of the foam 3 as a support is lost, and the foam 3 is damaged or the material 3 is not easily accommodated. is there.

The shape of the foam 8 may be a rectangular bar, a polygonal cross section,
A semi-circular rod-shaped material or any other material that can easily attach the material 3 may be used. In addition to the polyurethane foam described above, the foam 8 may be made of any material.
Polyethylene foam can also be used, and any other porous material such as sponge can be used as long as it has high elasticity and physical strength.

It should be noted that the double-sided pressure-sensitive adhesive tape 5 to which the release paper 4 is not attached can be used, and that a release agent such as a silicon-based release agent or a carbon-hydrogen-based release agent is applied without using the release sheet 4. Is a paper or plastic sheet of 0.08 to 0.18 mm. In addition to the double-sided pressure-sensitive adhesive tape 5, a single-sided pressure-sensitive adhesive tape and various kinds of adhesives conventionally used can be used as described above.

The number of slits 6 cut into the long plate-shaped release paper 4 of the double-sided adhesive tape 5, the number and width of the thin long plate-shaped release paper pieces 7, and the number of the narrow long plate-shaped paper pieces 10 of 0.2 mm or more. The thickness is as described above. In addition to the paper piece 10 having a thickness of 0.2 mm or more, a plastic sheet piece, a rubber piece, a felt piece, a foam piece, a cloth piece, or the like having a thickness of 0.2 mm or more may be used. What can be done is as described above.
