DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The releasable light-diffusing advertising sheet of the present invention is used by fixing the main part to the surface of an illuminated advertising base made of a transparent plastic molded product. More specifically, two functions of a function of fixing the transparent plastic sheet to the surface of a smooth electric lighting advertisement base material and a function of diffusing light from a light source on one side of a transparent plastic sheet on which a design for advertisement is printed. And a foamed synthetic resin layer having the following.

[0002]

2. Description of the Related Art In an advertising advertisement, an advertising sheet in which an advertising design is printed on one side of a transparent plastic sheet is adhered to the surface of an advertising advertising base material whose main part is formed of a transparent plastic molded product, and is directed downward or backward. Is illuminated from the light source. A conventionally used advertisement sheet has been adhered to the illuminated advertisement base material using an adhesive or a double-sided tape (see FIG. 4).

[0003] In recent years, there is a tendency that the types of products to be advertised are diversified in accordance with diversification of demand, and accordingly, the period for advertising one product is shortened. For this reason, it is necessary to change the contents of the advertisement one after another in the case of an electric advertisement.

[0004]

However, since the conventional advertising sheet uses a relatively strong adhesive such as an adhesive or a double-sided tape, and is adhered to the electric advertisement advertising base material, the sheet once attached is used. It took time and effort to remove it, and replacing the ad sheet was a tedious task. Also, after removal, the adhesive may remain on the surface of the illuminated advertising substrate,
At the boundary between the part with the adhesive and the part without the adhesive, the advertising sheet is torn, and not only the adhesive but also a part of the advertising sheet may remain on the surface of the illuminated advertising base material. Removing it was also a tedious task.

[0005] Further, when the conventional advertisement sheet is illuminated from the lower light source (see FIG. 5), when viewed from the front of the illuminated advertisement, the brightness of the advertisement pattern is lower between the lower part near the light source and the upper part far from the light source. Was uneven. Further, even in the case of illuminating from the rear light source (see FIG. 6), the light source is smaller than the area of the front surface of the illuminated advertising base material, so that when viewed from the front of the illuminated advertising, a portion close to the light source The brightness of the advertisement pattern was uneven between the distant part and the distant part.

Therefore, the present invention eliminates the above-mentioned disadvantages and can be easily replaced. Further, after removal, the adhesive or the advertisement sheet does not remain on the surface of the illuminated advertisement base material. An object of the present invention is to provide a removable light-diffusing advertisement sheet in which the brightness of an advertisement symbol is uniform over the entire surface.

[0007]

[Means for Solving the Problems] In order to achieve the above object, a removable light-diffusing advertising sheet of the present invention comprises:
A pattern layer was formed on one side of the transparent plastic sheet, and on top of that, micropores and internal bubbles having a diameter larger than the micropores continued, and the internal bubbles continued with other bubbles in a small-diameter tube. Light with a structure thickness of 150-500 μm
It was configured such that a foamed synthetic resin layer having a diffusion function was formed (see FIG. 1).

Further, a pattern layer is formed on one surface of the transparent plastic sheet, and fine holes and internal bubbles having a diameter larger than the fine holes continue on the other surface, and the internal bubbles are separated from other bubbles. A configuration in which a foamed synthetic resin layer having a light diffusion function and having a thickness of 150 to 500 μm and a continuous structure formed by a small diameter tube may be formed (see FIG. 2).

Hereinafter, the removable light-diffusing advertisement sheet of the present invention will be described in more detail with reference to the drawings.
FIGS. 1 and 2 are cross-sectional views showing one embodiment of the removable light-diffusing advertising sheet of the present invention. FIG. 3 is a plan view showing one embodiment of the removable light diffusion advertising sheet of the present invention. FIG. 4 is a perspective view illustrating a conventional light advertisement.
FIG. 5 is an explanatory sectional view showing a case where a conventional advertisement sheet is illuminated by a lower light source. FIG. 6 is an explanatory sectional view showing a case where a conventional advertising sheet is illuminated by a rear light source. Reference numeral 1 denotes a transparent plastic sheet, 2 denotes a design layer, 3 denotes a foamed synthetic resin layer, and 4 denotes an electric advertisement advertising base material.

As the transparent plastic sheet 1, it is preferable to use a plastic sheet made of polyethylene terephthalate or polyethylene. The reason for using these plastic sheets is that electric advertisements are often used outdoors, and because they are used for a short period of time for a certain period of time, a plastic sheet having durability is desirable. . The thickness is 25-10
0 μm.

The design layer 2 is formed on a transparent plastic sheet 1 by using a dye or a pigment which is usually used for printing, and by using a gravure printing method, a screen printing method, an offset printing method, etc., an advertising design including a pattern and characters. It was done. Design layer 2 for the purpose of lighting advertising
Is preferably translucent. However, the advertisement effect may be more exhibited by making the part that shows a color such as a metal color or the like that feels a material feeling or the character part non-translucent. Further, when the illuminated advertising base material 4 has a plurality of surfaces, the design layer 2 may be designed, for example, such that the upper surface and the four side surfaces of the illuminated advertising base material 4 are connected as shown in FIG. Alternatively, the upper surface and the four side surfaces may be separately designed.

The foamed synthetic resin layer 3 is for tightly fixing the removable light-diffusing advertising sheet to a smooth surface, and also has a light-diffusing function. The foamed synthetic resin layer 3 is formed on one side of the transparent plastic sheet 1. The foamed synthetic resin layer 3 has a flat continuous resin surface having fine pores on its surface, and the fine pores are continuous with internal bubbles having a diameter larger than the diameter of the resin. Has a continuous structure. When the foamed synthetic resin layer 3 is superimposed on a smooth surface, the foamed synthetic resin layer 3 comes into close contact, and is easy to peel off because no adhesive or double-sided tape is used, and is easy to fix again.
It has removability. The foamed synthetic resin layer 3 may be formed by printing on one side of the transparent plastic sheet 1 or may be formed into a sheet (for example, Japanese Patent Laid-Open No. 1-2590).
No. 43).

The thickness of the foamed synthetic resin layer 3 is 150 to 500 μm.
And If it is less than 150 μm, the adhesion to the transparent plastic molded article substrate 4 is not sufficient, and
When m exceeds m, the light transmittance is reduced. Therefore, the value should be set within the above range.

The main part of the illuminated advertising base material 4 is made of a transparent plastic molded product. The main part is a part to which an advertisement sheet is pasted and an electric advertisement is to be performed, and a part where the advertisement sheet is not pasted may be opaque. Further, instead of a transparent plastic molded product, another material having light transmittance, such as a glass plate, can be used. The shape of the illuminated advertising base material 4 is usually a side surface,
Although it is a hollow three-dimensional shape assembled on the top and bottom,
Any shape that can be illuminated and advertised can be considered, such as one in which each side is integrally formed, or a flat shape such as a panel. The surface of the illuminated advertising base material 4 is preferably a smooth surface so as to easily adhere to the foamed synthetic resin layer 3. This smoothness may be as smooth as the surface of an ordinary plastic plate, and it is not particularly necessary to provide a mirror finish. The removable light diffusion advertising sheet is fixed to the surface of the illuminated advertising base material 4 and is illuminated by a light source below or behind.

The removable light-diffusing advertising sheet of the present invention comprises:
It is suitable for use as a lighted advertisement of a sample product in the form of a cigarette case displayed in the cigarette vending machine shown in FIG. However, the removable light-diffusing advertising sheet of the present invention is not limited to cigarettes, but is also used as an electronic advertisement for a sample product such as soft drinks such as juice and audio compact disc cases displayed in a vending machine. Can also be used. Further, the present invention can be used not only for the three-dimensionally illuminated advertisement resembling the real thing as described above but also for a two-dimensionally illuminated advertisement such as an illuminated panel or a signboard.

[0016]

The foamed synthetic resin layer 3 of the removable light-diffusing advertising sheet of the present invention adheres to a smooth surface and has removability. Therefore, when the removable light-diffusing advertising sheet of the present invention is used, the removable light-diffusing advertising sheet is placed on the surface of the illuminated advertising base material 4 such that the foamed synthetic resin layer 3 is in contact with the surface, Apply pressure with a finger or the like to fix. When removing the removable light diffusion advertising sheet, it can be easily removed by lifting a part of the sheet with a finger.
Further, since the foamed synthetic resin layer 3 has a structure having bubbles inside, light from a light source is diffused when passing through the bubble structure.

[0017]

EXAMPLE On a transparent polyethylene terephthalate film having a thickness of 75 μm, an advertisement pattern of cigarettes to be displayed on the upper surface and four side surfaces of the illuminated advertisement base material was printed, and a urethane resin was further used thereon to form a 200 μm thick film. A synthetic resin layer was formed and cut along the shape of the design to produce a removable light diffusion advertising sheet (see FIG. 3). When the total light transmittance and the light diffusivity of the removable light diffusion advertising sheet were measured, the following measurement results were obtained. Total light transmittance (T) 70.8% Parallel light transmittance (PT) 8.0% Light diffusion (T-PT) 62.8% Haze ((T-PT) / T) 88.7%

Using transparent ABS resin, thickness 1 mm, size 1
A 5 cm × 10 cm × 1 cm hollow cubic advertising light base material was prepared. The removable light-diffusion advertising sheet was placed on the surface of the illuminated advertising substrate, and was lightly pressed with a finger and fixed. About as light source
When illuminated from below the illuminated advertising base material using a lamp of 10,000 candela, the entire advertising design was illuminated almost uniformly, confirming the light diffusion effect of the removable light diffusion advertising sheet. When lifted up with the edge of the removable light-diffusing advertising sheet lifted, the removable light-diffusing advertising sheet was easily detached from the electric advertising base material.

[0019]

The removable light-diffusing advertising sheet of the present invention has the above-described structure and function, and can be easily replaced as needed. Also, after removal, no adhesive or advertising sheet remains on the surface of the illuminated advertising substrate. further,
Since the foamed synthetic resin layer 3 diffuses the light from the light source,
When illuminated, the brightness of the advertisement symbol becomes uniform over the entire surface.
