Abstract

PROBLEM TO BE SOLVED: To form a white board capable of being carried with ease, and, manufactured at low cost. SOLUTION: This while board is formed such that white liner paper 2 is used on one face and generally used brown liner paper is on the other face, and a cardboard 1 provided with a corrugated board 4 is used as a core material between these liner papers 2, 3, wherein a film 5 consisting of synthetic resin such as polypropylene, polyethylene, and polyester is laminated on the surface of the white liner paper 2 via a transparent adhesive.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a whiteboard made of a corrugated board as a core material.

[0002]

2. Description of the Related Art Conventionally known whiteboards include a hardboard such as synthetic resin or wood plywood as a core material, the surface of which is coated with a synthetic resin such as polypropylene, polyethylene or polyester. Has been.

[0003]

However, since such a whiteboard is composed of a hard board such as synthetic resin or wood plywood using a core material, it has a heavy weight per unit area and is suitable for portable use. As a result, there is a problem that it is not suitable for carrying, and there is a problem that the cost becomes high.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a whiteboard which is lighter in weight, easier to carry and cheaper than conventional whiteboards.

[0005]

In order to solve this problem, the present invention uses a corrugated board made of liner paper having at least one side of white as a core material, and polypropylene, polyethylene, polyester, etc. on the surface of the liner paper. The gist of the invention is to laminate films made of the above synthetic resin. Further, according to the present invention, a corrugated board is used as a core material, a white paper sheet is laminated on the surface thereof, and a film made of a synthetic resin such as polypropylene, polyethylene or polyester is laminated on the surface of the paper sheet. It is what

With this structure, since the core material is made of corrugated board, it can be made lightweight as a whole.
And it can be provided at low cost.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, the first embodiment shown in FIG. 1 and FIG. 2 will be described. 1 has a white liner paper 2 on one side and a commonly used brown liner paper 3 on the other side. A corrugated board having corrugated sheets 4 provided between the corrugated board 3 and the corrugated board 1. The corrugated board 1 is used as a core material, and a film 5 made of a synthetic resin such as polypropylene, polyethylene or polyester is formed on the surface of the white liner paper 2 as a transparent adhesive. The whiteboard is made by stacking through. 6 is an edge material that surrounds the periphery of the whiteboard.

The film 5 is preliminarily laminated on the surface of the white liner paper 2 through a transparent adhesive in the corrugated board manufacturing process, and the corrugated board is produced using the liner paper 2 with the film 5. It is what is done.

Therefore, since the film 5 made of synthetic resin such as polypropylene, polyethylene and polyester is present on the surface of the whiteboard having such a structure,
The characters written on the surface of the film 5 can be easily erased with a cloth or paper using a commercially available whiteboard marker.

Next, a second embodiment shown in FIG. 3 will be described. A corrugated board 1 which is a core material used in the second embodiment uses brown liner papers 3 and 3 on both sides. Which is a general corrugated board, a white paper sheet 7 is laminated on the surface of a liner paper 3 on one side with an adhesive, and a synthetic resin such as polypropylene, polyethylene, polyester, etc. is formed on the surface of the paper sheet 7. The white board is made by laminating the film 5 made of a transparent material with a transparent adhesive.

The film 5 is laminated on the surface of a white paper sheet 7 in advance, and the paper sheet 7 with the film 5 is laminated.
Is laminated on the surface of the liner paper 3 on one side of the corrugated board 1.

Therefore, also in the whiteboard having such a structure, as in the first embodiment, the film 5 made of a synthetic resin such as polypropylene, polyethylene, or polyester is present on the surface, and is thus commercially available. With the whiteboard marker, the characters written on the surface of the film 5 can be easily erased with cloth or paper.

By the way, in each of the above-mentioned embodiments, the function of a whiteboard is simply provided. For example, in the first embodiment, a white liner paper 2 has a white liner such as hiragana, katakana, or alphabet on the back surface. It is also possible to print it so that it looks thin from the surface of the paper 2, so that children and the like can practice writing along the characters that appear to be light from the surface of the liner paper 2.
In the second embodiment, hiragana, katakana, alphabets, etc. are made to appear thin from the surface of the paper sheet 7 on the surface of the liner paper 3 on one side on which the white paper sheet 7 is laminated or on the back surface of the white paper sheet 7. It is also possible to print it on.

[0014]

As described above, according to the present invention, since the core material is made of a corrugated board, it can be made lightweight as a whole and can be provided at a low cost.
