Description

  The present invention relates to a transparent file for storing sheets, which is used to detachably attach a display sheet having a print or handwritten display unit to a transparent or opaque mounting surface.

Conventionally, as a transparent file for storing sheets of this type, a transparent sheet such as transparent vinyl is pasted together, and a part of the file has an opening. There is a printed matter storage file that is attached to an indoor side surface of a transparent object such as a glass window or a glass door by an adhesive member (see, for example, Patent Document 1).
The file can be easily exchanged on the indoor side of a transparent object such as a glass window or glass door by attaching a double-sided tape or the like as the adhesive member to the outer edge of the file. I have to.
As the adhesive member, an adhesive or the like is considered in addition to the double-sided tape, and depending on the material of the file, it is adhered to a crow window or the like by a suction cup.

Registered Utility Model No. 3158542

By the way, even if it is possible to easily exchange printed materials such as posters and leaflets on the indoor side with respect to the printed material storage file, for example, when the printed material is no longer needed or when it is easier to replace the printed material after removing the file The file itself may be peeled off from objects such as glass windows and glass doors.
However, in the conventional printed matter storage file, since the file is attached as an adhesive member with a double-sided tape or an adhesive, the adhesive components such as the double-sided tape and the adhesive deteriorate over time and stick to the surface of the object. Accordingly, there is a problem that it becomes difficult to return the surface of the object after the file is peeled off to the state before pasting, and the aesthetic appearance is impaired.
Furthermore, since only the outer edge part (part) of the file is attached to the object with an adhesive member (double-sided tape, adhesive, or sucker), between the center part of the file without the adhesive member and the object, An air layer that does not contribute to adhesion is generated. As a result, the adhesive force is insufficient, and there is a risk of dropping the entire file.
In addition, as an advertising method for passers-by and visitors, transparent objects such as posters and flyers are put in a file and pasted on the indoor side of transparent objects such as glass windows and glass doors using adhesive members. There is an example in which the advertisement content in the file can be seen from the outdoor side through.
However, when such an advertisement method is realized with a conventional printed matter storage file, there is a problem that the advertisement content is difficult to see because light is reflected by an air layer generated between the center portion of the file having no adhesive member and the object. It was.

  An object of the present invention is to cope with such a problem, and provides a transparent file for storing sheets that can be repeatedly attached and peeled over and over without an adhesive component adhering to the mounting surface. It is for the purpose.

  In order to achieve such an object, the present invention provides a sheet storage transparent file that supports a display sheet and is attached to a mounting surface, and a file main body having a support portion on which the display sheet is detachably supported; An adhesive layer formed on a back surface of the file body facing the mounting surface, and the adhesive layer has an adhesive surface that is dispersedly bonded to the mounting surface by van der Waals force. To do.

In the present invention having the above-described features, the adhesive sheet of the adhesive layer formed on the back surface of the file body is attached to the attachment surface in a state where the display sheet is supported on the support part of the file body. The minute irregularities fill the minute irregularities on the mounting surface, and both are electrostatically coupled. Therefore, the support portion of the file body is dispersed and bonded to the mounting surface by van der Waals force, and the display sheet is positioned at a predetermined position by the support portion. Furthermore, even if a fine foreign matter adheres to the fine irregularities on the adhesive surface or the mounting surface and the adhesive force is reduced, the adhesive force is recovered by removing the foreign matter by washing, and repeated adhesion is possible.
Accordingly, the adhesive surface can be repeatedly attached to and peeled from the mounting surface without adhesion of the adhesive component to the mounting surface.
As a result, the adhesive component of the adhesive surface does not deteriorate over time and stick to the mounting surface compared to conventional ones in which the file is attached as an adhesive member with double-sided tape or adhesive, etc. It is possible to easily return the mounting surface to the state before pasting, and the aesthetic appearance can be maintained.

It is explanatory drawing which shows the whole structure of the transparent file for sheet storage which concerns on embodiment of this invention, (a) is a front view of a display sheet, (b) is the front of the state which supported the display sheet in the support part of the file main body. FIG. 2C is a longitudinal side view of FIG. It is a partially-cutaway perspective view of the state seen through from the attachment surface side.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The sheet storage transparent file A according to the embodiment of the present invention supports a printed or handwritten display sheet B as shown in FIGS. 1 (a), 1 (b), (c) and FIG. A transparent case or a transparent case in which both the display parts B1 and B2 on the front and back sides of the display sheet B can be seen through, or only one of the display parts B1 and B2 can be seen through by being detachably attached to C. It is a holder.
More specifically, the sheet storage transparent file A according to the embodiment of the present invention includes a file body 1 having a support portion 1a on which the display sheet B is detachably supported, and a back surface portion facing the mounting surface C in the file body 1. The adhesive layer 2 formed on 1b is provided as a main component.

The file main body 1 is formed into a sheet shape with a transparent or translucent deformable soft synthetic resin to which a colorant is added, and a support portion 1a on which a display sheet B described later is supported so as to be freely inserted and removed, and the back surface of the display sheet B Has a back surface portion 1b facing each other.
Specific examples of the soft synthetic resin constituting the file body 1 are transparent, such as olefin resin (polyolefin), vinyl chloride resin (polyvinyl chloride), or translucent deformable resin to which a coloring agent is added. Is used.

The support portion 1a is a container case or a locking space for supporting the display sheet B, which will be described later, with respect to the file main body 1 so as not to drop, and the entire front surface of the display sheet B or the front surface of the display sheet B between the back surface portion 1b. It is formed so as to cover the part.
As specific examples of the support portion 1a and the back surface portion 1b, in the case shown in FIGS. 1B, 1C, and 2, two rectangular sheets 1S and 1T are overlapped, and the three sides are heated and melted or adhesive. For example, the support portion 1a and the back surface portion 1b are integrally formed by forming the fixed portion 1c having a predetermined width in a U-shape.
Explaining in detail, the support portion 1a is a container that opens the remaining one side 1d that is not fixed by heat melting or adhesive, and a storage space 1U for the display sheet B is formed between the two rectangular sheets 1S and 1T. is there. A front side rectangular sheet 1S covers the entire front surface of the display sheet B, and a back side rectangular sheet 1T serves as a back surface portion 1b.
Although not shown in the drawings as other examples, two sheets formed in a shape other than a rectangle, two sheets formed in different shapes from each other, or the outer edge of the display sheet B as the support portion 1a If the display sheet B can be detachably supported, such as by changing the shape so as to partially cover a part or the like, the structure can be changed to a structure other than the illustrated example.

The adhesive layer 2 has an adhesive surface 2a that disperses and adheres to the attachment surface C with van der Waals force (intermolecular force).
That is, the adhesive surface 2a has fine unevenness (not shown) that fits with each other with substantially the same size as the fine unevenness that exists on the mounting surface C described later. By superimposing the adhesive surface 2a of the adhesive layer 2 along the mounting surface C, which will be described later, and pressurizing with a predetermined pressure, the fine irregularities of the adhesive surface 2a closely contact (adsorb) with the fine irregularities of the mounting surface C without any gaps. Further, it is configured to electrostatically couple fine irregularities.

By the way, in a state in which the adhesive layer 2 is peeled off from the mounting surface C, which will be described later, fine foreign matters such as dust are present on either or both of the fine unevenness of the adhesive surface 2a and / or the fine unevenness of the mounting surface C. It can be considered that the fine irregularities are adhered and clogged.
If any one of the fine irregularities is clogged, even if the adhesive surface 2a of the adhesive layer 2 is overlapped and pressed along the mounting surface C, a gap is generated between the fine irregularities, and electrostatic bonding is impossible. Accordingly, it becomes difficult to disperse and adhere with van der Waals force (intermolecular force), and the adhesive force of the adhesive surface 2a to the attachment surface C may be reduced.
In such a case, the fine unevenness to which fine foreign matters such as dust are adhered is washed to remove the foreign matters, so that the adhesive force is recovered and it is possible to repeatedly adhere.

Furthermore, the adhesive surface 2a of the adhesive layer 2 is laminated and formed on the back surface portion 1b of the file body 1 so as to cover at least the entire back side display portion B2 of the display sheet B, which will be described later. It is preferable that the portion of the display sheet B facing the back side display portion B2 is dispersed and bonded to the mounting surface C, which will be described later, by the van der Waals force (intermolecular force) by the bonding surface 2a.
As a specific example of the adhesive layer 2, in the case shown in FIGS. 1B, 1C, and 2, the adhesive 2b is applied to the entire back surface 1b of the file body 1 with a predetermined thickness and cured. An adhesive surface 2a is laminated in a planar shape over the entire back surface portion 1b of the file body 1.
As the adhesive constituting the adhesive layer 2, a urethane-based adhesive such as polyurethane, or a chemical reaction curable adhesive such as a silicone-based adhesive or an acrylic adhesive is used. It is preferable to form the transparent adhesive layer 2 and the adhesive surface 2a using a transparent adhesive.
Although not shown in the drawings as another example, the back side 1b of the file body 1 can be covered with the back side 1b of the file body 1 as long as the entire back side display part B2 of the display sheet B can be covered. It is also possible to form the adhesive surface 2a on only a part of the portion 1b in a layered manner, or to form and change the adhesive surface 2a in a surface shape by other methods instead of applying the adhesive 2b. .

The display sheet B is composed of a printed matter such as a poster or a flyer or a handwritten pop advertisement card, and the size of the display sheet B is smaller than the support portion 1a of the file body 1 so that it can be taken in and out of the support portion 1a. Yes.
The display sheet B has printed and handwritten display portions B1 and B2 on both or both of the front and back surfaces.
As a specific example of the display sheet B, in the case shown in FIGS. 1B, 1C, and 2, the front display portion B1 is formed on the surface of the display sheet B, and the back side of the display sheet B is the back side. A display portion B2 is formed. In the illustrated example, characters and frame lines are provided as the front display unit B1 and the back display unit B2.
Although not shown as other examples, the front display portion B1 is formed only on the front surface of the display sheet B, the back display portion B2 is formed only on the back surface of the display sheet B, the front display portion B1 and the back display portion As B2, it is also possible to change characters and frame lines to marks and figures.

The attachment surface C is a smooth wall surface to which the back surface portion 1 b of the file body 1 is attached by the adhesive layer 2.
Specific examples of the mounting surface C include a transparent wall surface made of a transparent material such as a glass window and a glass door, and an opaque wall surface made of an opaque material regardless of the presence or absence of wallpaper.

According to the sheet storage transparent file A according to the embodiment of the present invention, the adhesive layer formed on the back surface portion 1b of the file body 1 in a state where the display sheet B is supported on the support portion 1a of the file body 1. 2 is attached to the mounting surface C.
Thereby, the fine unevenness of the adhesive surface 2a of the adhesive layer 2 fills the fine unevenness of the mounting surface C, and both are electrostatically coupled, and a van der Waals force is generated between them. Therefore, the support portion 1a of the file body 1 is dispersed and bonded to the attachment surface C by van der Waals force (intermolecular force), and the display sheet B is positioned at a predetermined position by the support portion 1a and is held immovably.
Furthermore, since the adhesive surface 2a of the adhesive layer 2 is a dispersion adhesive by van der Waals force, even if a fine foreign matter adheres to the fine irregularities of the adhesive surface 2a or the mounting surface C and the adhesive force decreases, it can be washed. By removing the foreign matter, the adhesive force is recovered, and repeated adhesion is possible.
Accordingly, the adhesive surface 2a can be repeatedly attached to and peeled from the attachment surface C without any adhesion component of the adhesive surface 2a adhering to the attachment surface C.
As a result, the adhesive component of the adhesive surface 2a does not stick to the attachment surface C due to deterioration over time, and the attachment surface C after the file body 1 is peeled off can be easily returned to the state before the attachment. It becomes possible and can maintain aesthetics.

In particular, the adhesive layer 2 is formed in a layered manner so as to cover the entire (back side) display portion B2 of the display sheet B on the back surface portion 1b of the file body 1.
In this case, at least a portion of the back surface 1b of the file body 1 facing the (back side) display portion B2 of the display sheet B is dispersed by van der Waals force (intermolecular force) with respect to the attachment surface C by the adhesive surface 2a. Glued. Therefore, an air layer does not occur between the part covering the entire (rear side) display part B2 of the display sheet B and the attachment surface C on the adhesive surface 2a, and adheres in a planar shape.
Therefore, the adhesive strength by the adhesive layer 2 can be improved.
As a result, the file main body 1 from the attachment surface C for a long period of time compared to the conventional one in which only the outer edge (part) of the file is attached to the object with an adhesive member (double-sided tape, adhesive, or sucker). Prevents falling accidents and has excellent safety.

Next, an embodiment of the present invention will be described with reference to the drawings.
In this embodiment, as shown in FIGS. 1 (a), (b), (c) and FIG. 2, the back side display portion B2 is transparent through the back surface portion 1b of the file body 1 facing the back side display portion B2 of the display sheet B. Thus, the adhesive layer 2 that is formed of a transparent material and faces the mounting surface C made of a transparent material including glass is formed of a transparent material so that the back side display portion B2 is transparent.
That is, the file body 1 in which the display sheet B having the back side display portion B2 is supported by the support portion 1a is attached to the transparent mounting surface C such as a glass window or a glass door by the adhesive surface 2a of the adhesive layer 2. . Thereby, the transparent adhesive layer 2 and the transparent back surface portion 1b are transmitted from the outside of the transparent mounting surface C, and the back side display portion B2 of the display sheet B attached to the inside of the mounting surface C can be seen through. I am doing so.

Further, in the examples shown in FIGS. 1A, 1B, 1C and 2, the front display portion B1 is transparent through the support portion 1a of the file body 1 facing the front display portion B1 of the display sheet B. It is made of a transparent material.
That is, the display sheet B having the front side display part B1 and the back side display part B2 on both front and back sides is supported by the support part 1a, and the front side display part B1 of the display sheet B can be seen through through the transparent support part 1a. I have to.

According to the sheet storage transparent file A according to the embodiment of the present invention, even if the display sheet B is viewed from the transparent attachment surface C side with the transparent adhesive layer 2 and the transparent back surface 1b interposed therebetween, the adhesive layer 2 and the mounting surface C, an air layer is not generated and is closely adhered to the surface, so that a part of the display part B1 is not partially reflected and all of the display part B2 can be seen through.
Therefore, all the display portions B2 of the display sheet B attached from the outside to the inside of the transparent mounting surface C can be seen through without any obstacles.
As a result, compared with the conventional one in which an adhesive member (double-sided tape, adhesive, or sucker) is arranged on the outer edge (part) of the file, the advertisement content described in the display portion B1 of the display sheet B is viewed from the outdoor side. There is an advantage of being able to see without obstacles.
Furthermore, when the display sheet B having the front side display part B1 and the back side display part B2 on both front and back sides is supported by the support part 1a as in the illustrated example, both the outward and inward sides of the display sheet B are surely provided. There is an advantage that it can be effectively used as an advertising method.

In the previous embodiment, the back side display portion B2 of the display sheet B can be seen through from the outside of the transparent mounting surface C. However, the present invention is not limited to this. The display body B having the file body 1 supported by the support portion 1a is attached to the adhesive surface 2a of the adhesive layer 2, and the transparent display portion 1a is transmitted inside the mounting surface C to transmit the front side display portion of the display sheet B. B1 may be made visible.
Further, in the illustrated example, the display sheet B having the front side display part B1 and the back side display part B2 on both front and back sides is supported by the support part 1a, and the front side display part B1 of the display sheet B is seen through through the transparent support part 1a. However, the present invention is not limited to this, and the display sheet B having only the back side display portion B2 is used, and the blank surface or the colored surface is transmitted through the transparent support portion 1a inside the mounting surface C. You may make it visible.
