Description

[Detailed description of the invention] The present invention is a lottery ticket in which lottery symbols such as numbers and alphabets are applied to the number slot provided on a part of the sheet base material. This invention relates to a lottery ticket that allows it to be easily determined whether or not a lottery has been held.

2. Description of the Related Art Conventionally, lottery tickets have been widely used in which lottery numbers such as numbers or alphabets are placed on the number slots, and the winning numbers are specified in a later lottery to determine the winner or loser. However, as these types of lottery tickets have become more widely available, counterfeiting and falsification have become more common. There are several ways to falsify the lottery numbers on a lottery ticket, including erasing part or all of the lottery symbol by some means and then rewriting another lottery symbol to make it a winning symbol. There are various methods of tampering, including the so-called cut-and-paste method, in which the lottery ticket is cut out and replaced with a lottery symbol cut from another lottery ticket.

For the former type of tampering, there are preventive measures that will make it clear that the lottery symbol has been tampered with, depending on the method of erasing the lottery symbol, such as adding a background pattern, forming the lottery symbol with highly permeable number printing ink,
Alternatively, a method of using thin paper as the sheet base material has been taken, but recent tampering by cutting and pasting is extremely sophisticated, making it difficult to detect tampering.

The present invention was developed in view of the above-mentioned circumstances, and aims to provide a lottery ticket in which tampering with lottery symbols by cutting and pasting can be easily determined by visual inspection.

That is, in the present invention, a lottery symbol such as a number or an alpha alphabet is applied to the number position on the sheet base material, and a lottery symbol such as a number or an alphabet is placed above and/or below the lottery symbol by penetrating into the sheet base material to select the desired part. The present invention relates to a lottery ticket with cut-paste prevention measures, characterized in that an image-forming material dyed in a hue of 1 is coated with a cut-paste prevention layer made of a non-hidden film-forming material that is not dyed.

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic perspective view of a lottery ticket 1 according to the present invention, and FIG. 2 is a sectional view taken along the line-A' of the lottery ticket 1 shown in FIG. In the figure, 2 is natural fiber paper, synthetic fiber paper,
A number seat on the sheet base material 3 such as semi-synthetic fiber paper, 4 is a number formed on the part of the number seat 2 on the sheet base material 3, a lottery symbol such as Alphabet, 5 is a number formed on the top of the lottery symbol 4. The cut-and-paste prevention layer is shown in each figure. The location where the cut-and-paste prevention layer 5 is formed is not limited to the upper part of the lottery symbol 4, but may be formed at the lower part of the lottery symbol 4, or both the upper and lower parts of the lottery symbol 4. This cut and paste prevention layer 5 is
A non-obscuring film-forming material 12 that is not dyed by the image-forming material that penetrates into the sheet base material 3 and dyes the permeated portion in a desired hue allows printing methods such as offset printing, screen printing, flexo printing, etc. It may be formed by a coating method using a roll coater or a bar coater. The cut-and-paste prevention layer 5 is preferably a solid layer that completely covers the number seat 2, and its size is smaller than the number seat 2 in the top and bottom.
It is preferable to make both the left and right sides larger (for example, about 1.5 times).

On the other hand, when a commercially available water-based pen or highlighter pen is used as the image forming material, the film-forming material constituting the cut-and-paste prevention layer 5 may be OP varnish for offset printing, UV varnish, etc.
Specific examples include gravure varnish and the like. Further, this film-forming material does not need to be transparent, and may have a concealing property that allows the lottery symbol 4 and ground pattern located at the bottom to be reliably determined.

The lottery ticket 1 of the present invention has the above configuration, so
An image forming material 1 is placed on the top of the number seat 2 to permeate the sheet base material 3 and dye that part in a desired hue.
Even if 2 is applied, number 2 will not be dyed. However, as shown in Figures 2 and 3,
Part A of the number seat of lottery ticket 1 (sheet base material 3', lottery symbol 4', cut-and-paste prevention layer 5' in the area indicated by the x mark)
The cut and paste lottery ticket 11 obtained by cutting out the sheet base material 3'', the lottery symbol 4'', and the cut-and-paste prevention layer 5'' that were cut from the number slots of another lottery ticket, can be obtained by cutting and pasting the sheet base material 3'' from the number seat of another lottery ticket. Although it is difficult to detect tampering, when the image forming material 12 is applied from above the number seat, the image forming material 12 passes through the cut and penetrates into the sheet base materials 3, 3''. It was partially stained, and it was immediately obvious that it had been tampered with by cutting and pasting.
Although the hue of the image forming material used to determine whether or not it has been tampered with by cutting and pasting is not particularly limited, the hue of the sheet base material 3, lottery symbol 4, etc. should be taken into account so that dyeing on the sheet base material 3 can be clearly determined. You should choose a hue that suits your needs.

Further, the thickness of the sheet base material 3 is not particularly limited, but the thinner the material, the easier it is for the image forming material 12 to penetrate and reach the back surface, so that the hue of the dyed cut portion can be clearly seen from the back surface. As a result, cutting and pasting can be determined more reliably.

The present invention has the above-mentioned configuration, and as long as there is an image forming material that dyes the sheet base material, it is possible to quickly and reliably determine whether there has been tampering by cutting and pasting, and it has a great practical effect. be.
