BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bulletin board, and more specifically, a bulletin board which can be repeatedly attached to a bulletin board without using a push pin or an adhesive tape, and a bulletin board using the bulletin board. It relates to the device.

[0002]

2. Description of the Related Art In a conventional posting device, a surface of a substrate such as plywood is covered with a surface material such as a cork sheet, a woven cloth, a synthetic resin sheet or a composite sheet material to form a posting surface. It is common to stick a sign using a push pin or an adhesive tape.

[0003]

However, in the conventional posting device as described above, when a push pin is used, a pin hole mark remains on the posting surface to make the appearance unpleasant, and the push pin is repeatedly used. In the meantime, not only the surface material such as the cork sheet on the surface but also the plywood of the board becomes full of holes and the push pin cannot be cut.Also, when using adhesive tape, keep the posted material for a long time. If it is pasted, there is a problem that the adhesive or the like of the adhesive tape remains on the display surface after the adhesive tape is peeled off to contaminate the display surface.

In view of the above points, the present invention is capable of adhering a post without the need for push pins, adhesive tapes, etc., unlike the conventional posting devices, and furthermore, the post can be adhered and peeled off. The present invention provides a notice sheet and a notice device using the notice sheet that can be repeatedly used for a long period of time without being contaminated, damaged, or leaving a mark of the notice.

[0005]

Means for Solving the Problems A first bulletin sheet according to the present invention for achieving the above object is a non-woven fabric, a woven fabric,
A soft synthetic resin layer is formed on at least the surface of a film-shaped or sheet-shaped base material such as paper, synthetic resin film, synthetic resin sheet, or synthetic rubber sheet, and foamed holes opened in the surface direction on the soft synthetic resin layer. And a concave hole is provided on the surface of the foamed synthetic resin layer while forming a foamed synthetic resin layer having adhesiveness due to the adsorption action of the surface opening.

The second bulletin sheet according to the present invention is
A soft synthetic resin layer is formed on at least the surface of a film-shaped or sheet-shaped substrate such as a non-woven fabric, a woven fabric, paper, a synthetic resin film, a synthetic resin sheet, or a synthetic rubber sheet, and a surface direction is formed on the soft synthetic resin layer. Forming a foam synthetic resin layer having adhesiveness due to the adsorption effect of the foam pores opened on the surface, and printing on a part of the surface of the foam synthetic resin layer to form a foam synthetic resin layer. It covers the surface opening.

The foamed synthetic resin used in each of the above-mentioned bulletin sheets includes a foamed synthetic resin mainly composed of an acrylic ester resin, a foamed synthetic resin mainly composed of a urethane resin,
Further, there may be mentioned a foamed synthetic resin mainly composed of both of them. In particular, a foamed synthetic resin layer mainly composed of a foamed acrylic acid ester resin is formed on the surface of a non-woven fabric impregnated with a synthetic resin mainly composed of a soft acrylic acid ester resin. Those formed are preferred. This is because the acrylic ester resin itself has an adhesive property in addition to the adsorption effect of the foamed holes.
Further, in this case, if a cold-resistant synthetic resin such as a cold-resistant acrylic ester resin or a cold-resistant urethane resin is blended with the acrylic ester resin, the use environment, especially the surface of the bulletin board due to changes in temperature at the place of use, etc. It is possible to prevent a decrease in adhesion. In addition to the acrylic ester resin, a urethane resin and a mixture thereof with a cold-resistant urethane resin can be preferably used. The thickness of the foamed synthetic resin layer on the surface of the posted sheet is 0.3 to 1.
0 mm, preferably 0.35 to 0.75
It is about millimeter. By setting the thickness of the foamed synthetic resin layer in the above range, elasticity can be imparted to the foamed synthetic resin layer so that the foamed synthetic resin layer exhibits an adsorbing action, and a concave hole is formed on the surface of the foamed synthetic resin layer. The work at that time, specifically, embossing by hot pressing and the like are facilitated.

The adhesion mechanism of the posted matter to the surface of the posted sheet according to the present invention is such that the initial adhesion of the posted matter to the surface of the sheet is secured by the foamed synthetic resin layer located on the surface of the sheet.
In addition to the adsorbing action of the foamed synthetic resin layer, the subsequent continuous adhesion is ensured by the concave holes formed on the surface of the foamed synthetic resin layer. That is, in order to stick the posting on this posting sheet, the posting is pressed against the sheet surface, and the posting is brought into close contact with the sheet surface by the adsorption action of the foaming holes of the foamed synthetic resin layer opened on the sheet surface. To do. In this case, the soft synthetic resin layer located below the foamed synthetic resin layer increases the elasticity of the entire sheet in combination with the elasticity of the foamed synthetic resin layer, so that the initial adhesion by the foamed synthetic resin layer is improved. Further, the soft synthetic resin layer also serves as a barrier for preventing air from leaking to the base material side of the back surface to secure the adsorption action when the article is adsorbed by the foamed holes. Furthermore, this synthetic resin layer is a base material,
As a result, the sheet also has a function as a reinforcing material for the sheet. Therefore, the soft synthetic resin layer located between the base material and the sheet surface is preferably made of a synthetic resin material having good adhesion to both the base material and the foam synthetic resin layer on the surface. In particular, a non-woven fabric is used as the base material, and this non-woven fabric is impregnated with an acrylic ester resin as in the foamed synthetic resin layer, which is a preferred embodiment.

Further, if an attempt is made to ensure continuous adhesion for a long period of time only by the adsorption action of the foaming pores of the foamed synthetic resin layer as described above, the foamed synthetic resin layer has an extremely dense and strong adsorption structure. However, when the foamed synthetic resin layer has such a dense and strong adhesion structure, the adhesion mechanism of the posted material is almost in an adhered state, and in this case, the adhesion is continued for a long period of time. After that, the posted matter tends to be difficult to peel off, and a mark of the posted matter remains on the sheet surface. Therefore, in the first bulletin sheet according to the present invention, the concave holes provided on the surface of the foamed synthetic resin layer have a more macroscopic adsorption action than the foamed holes of the foamed synthetic resin layer. Along with the so-called microscopic adsorption action of the foamed synthetic resin layer, the adhesion of the posted matter is ensured for a long period of time, and the macroscopic adsorption action causes the posted matter to adhere to the foamed synthetic resin layer. Unlike the microscopic adsorption mechanism due to the foaming holes of the layer, no trace of the posted matter is left on the surface of the posted sheet even when the printed matter is continuously attached. Further, in the second bulletin board according to the present invention, the surface of the foamed synthetic resin layer is partially printed, and the opening of the foam hole is covered to adjust the adsorption action of the surface of the foamed synthetic resin layer. Thus, it is possible to prevent the posted matter from being excessively adhered to the surface of the foamed synthetic resin layer due to the adsorption action of the foamed pores to make it impossible to peel it off. Of course, it is also possible to adjust the adsorption action of the expanded synthetic resin layer by simultaneously using both the concave holes formed on the surface of the expanded synthetic resin layer and the printing on the surface.

The bulletin board according to the present invention as described above is
An adhesive layer may be provided on the back surface of the sheet in advance, or an adhesive agent may be applied to the back surface of the sheet so as to be stretched on the wall surface or partition of the room for use. As the adhesive layer on the back surface of the base material, a known material such as an adhesive or an adhesive can be used.

[0011] Further, by stretching this signboard sheet on the surface of the substrate, the signboard sheet can be constructed in the same manner as the signboard surface in the conventional signboard device. The signing device according to the present invention comprises the signing sheet stretched on the substrate as described above.
As the substrate in this case, by using a substrate having a smooth and hard surface on which the sign sheet is stretched, the adsorptive effect of the foamed synthetic resin layer when sticking the sign by pressing the sign on the surface of the sign sheet is used. It can be exhibited more effectively. Examples of such a base material include a metal plate, a hard synthetic resin plate, a wood plywood, and the like. Among them, the metal plate can be said to meet the above conditions in terms of smoothness, hardness and the like.

[0012]

Further, in this embodiment, a concave hole 32 is formed on the surface of the foamed synthetic resin layer 3. This recess 32
As a specific forming method, the surface is formed by embossing the surface of the foamed synthetic resin layer 3 by hot pressing as shown in FIG. 2. In the example shown in FIG. Although it is a through hole that reaches 1, the depth of the recess 32 can be set to the middle of the foamed synthetic resin layer 3. In this case, the embossing pattern, the density, etc. are set to the degree of adhesiveness required for the bulletin board A in consideration of the thickness of the foamed synthetic resin layer 3 and various conditions such as the material forming the foamed synthetic resin layer 3. It is adjusted accordingly. Further, the concave hole 32 can be continuously formed. Also, this recess
By providing 32 on the surface of the bulletin board in a pattern of, for example, a grid, it becomes possible to facilitate the positioning of the bulletin board with respect to the presentation surface. The bulletin board A is formed by providing the adhesive layer 4 on the back surface of the bulletin board A by applying an adhesive, an adhesive or the like. In practical use, a protective sheet 5 made of a polyethylene film having a thickness of about 15 to 30 μm for protecting the foamed synthetic resin layer 3 is placed on the front side of the bulletin board A, and a release sheet is placed on the adhesive layer 4 on the back side. , These shall be removed at the time of use.

FIG. 3 is a sectional view showing another embodiment of the bulletin board A according to the present invention, in which the printed synthetic resin layer 3 formed on the base material 1'is partially printed on the surface thereof. By applying 35 to partially cover the foaming pores 32 on the surface involved in the adsorption action and limiting the adsorption action on the surface of the foamed synthetic resin layer 3, the posted matter is more than necessary on the surface of the foamed synthetic resin layer 3. It is possible to prevent the film from sticking to and becoming unpeeable. As the printing 35, for example, as shown in FIG.
By printing in a grid pattern on the display surface, it is possible to facilitate the positioning when the display object is stretched, but this print pattern is not particularly limited, and the print area is also the expanded synthetic resin layer. It may be set as appropriate in consideration of the adsorption performance and the like of item 3.

A notice sheet A according to the present invention as described above
Is stretched on a wall surface in the room by using the adhesive layer 4 on the back surface, and a printed matter or the like is pressed against the surface of the foamed synthetic resin layer 3 on the surface of the printed sheet A. In addition to the action, the adhesiveness of the acrylic ester resin itself causes the posted matter to adhere to the surface of the posted sheet A, so that the posted matter can be posted without using a push pin or an adhesive tape as in the conventional case. Does not leave pin holes or marks such as adhesive. Further, the concave hole 32 provided so as to reach the nonwoven fabric 1 as the base material from the surface of the foamed synthetic resin layer 3 can ensure stable adhesiveness for a long period of time, and the concave hole 32 and the foamed synthetic resin layer 3 can be secured. By the printing 35 on the surface, the adsorption force on the surface of the foamed synthetic resin layer 3 is adjusted so that the mark of the posted matter may remain on the surface of the foamed synthetic resin layer 3 even after the sign is attached for a long period of time. No, it can be easily removed.
