Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a color memo panel on which notes can be written on the panel surface with a felt-tip pen or the like.

[Prior Art] A conventional device similar to this type is shown in FIG. 2.

That is, the core material 11 is made of an enamel plate.
There is a whiteboard in which a thin iron plate 12 is placed on top of the whiteboard, and a special coating such as finely powdered white resin 13 is applied to the thin iron plate by electrodeposition coating or the like.

[Problems to be solved by the invention] However, in the above-mentioned whiteboard, [1] Enamel and thin iron plates are used to construct the board, so its specific gravity is large, and it is difficult to install the board in order to hold it. In some cases, a sufficient holding device such as drilling is required.

[2] Since the board is white, it is necessary to use felt-tip pens of the desired color to create colors, which requires a large number of pens of different colors.

[3] Since the surface is painted, parts of the letters or graphics remain in the recesses of the uneven surface, which tends to cause what is called an afterimage phenomenon.

[4] If you accidentally write with a permanent marker, it is difficult to erase it.

There were other problems.

This invention was made in view of the problems of the conventional technology, and its purpose is to allow the use of oil-based pens that are lightweight and have no afterimage phenomenon, and to provide the desired color. This paper aims to provide a color memo panel that can be configured as follows.

[Means for Solving the Problem] In order to achieve the above object, the color memo panel of this invention consists of a core material made of polyethylene foam resin, and a thin aluminum plate, a color sheet of vinyl chloride, and a polyester film with a hardened surface sequentially placed on top of a core material made of polyethylene foam resin. It is a layered product.

[Function] When characters or drawings are written on the polyester film surface with a water-based felt-tip pen or an oil-based felt-tip pen, since the surface of the polyester film is hardened and smooth, ink will not penetrate into the polyester film. It can be easily erased with paper or cloth.

Furthermore, the vinyl chloride color sheet and aluminum thin plate sufficiently resist the pressure of the pen when writing the characters or drawings.

Furthermore, since the panel is made of a core material made of polyethylene foam resin and a thin aluminum plate, the specific gravity is lower than that of the conventional whiteboard.

Furthermore, the vinyl chloride color sheets can be easily molded into various colors, and it is also possible to separately arrange the vinyl chloride color sheets of various colors in one panel, for example.

[Example] FIG. 1 shows a sectional view of an example of a color memo panel according to this invention.

In the figure, reference numeral 1 denotes a core material made of polyethylene foam resin having a thickness of about 2 mm, which is formed by foaming polyethylene resin into a plate shape.

A thin aluminum plate 2 with a thickness of about 150 microns is laminated on the core material 1, and a color sheet 3 of vinyl chloride molded in a desired color and with a similar thickness is laminated on the thin aluminum plate 2. A transparent polyester film 4 with a hardened surface and having a similar thickness is laminated on the vinyl chloride color sheet 3.
A color memo panel is formed by applying adhesive to the back surfaces of the thin aluminum plate 2, color sheet 3, and film 4, and pressurizing the laminated structure in a laminator.

Note that the vinyl chloride color sheet 3 is not limited to one color over the entire surface, but it is also possible to separate sheets of different colors and arrange them on the aluminum thin plate 2.

The color memo panel can be used on walls, ceilings,
It may be used by directly fixing it to a floor, desk, screen, etc., or it may be used as a stand-alone portable device.

Furthermore, the shape of the color memo panel is not limited to a rectangular shape, and may be, for example, a disk, or a cylinder,
It is also possible to use a three-dimensional shape such as a polygonal prism.

[Effects of the invention] The color memo panel according to this invention uses a core material made of polyethylene foam resin and a thin aluminum plate as the materials constituting the panel, so the specific gravity is lower than that of the conventional whiteboard, and the color memo panel has a lower specific gravity than the conventional whiteboard. It is easy to handle and does not require any special holding device.

Furthermore, since the panel can easily have a desired color on the vinyl chloride color sheet, there is no particular need to select the color using a felt-tip pen.

Furthermore, since the surface of the panel is hardened and smooth, ink does not penetrate into the polyester film and can be easily erased with paper or cloth, resulting in the so-called afterimage phenomenon. Alternatively, water-based or oil-based felt-tip pens can be used.

Furthermore, PVC colored sheets are not limited to one color, but different colors can be separated and placed on the thin aluminum plate, so it is also possible to take notes with items written in different colors. At the same time, you can also get a memo panel with a unique design.
