Abstract

(57) [Summary] [Purpose] By forming a printed surface with transparent fluorescent ink on one side of a transparent film and providing an adhesive layer, the printed display surface of the adherend is made clear, and by applying ultraviolet light. To provide a printed adhesive label that facilitates the detection of tampering. [Structure] A desired printing surface was formed on one side of a transparent film using transparent fluorescent ink, an adhesive layer was formed on the printing surface, and the printing surface could be detected by applying ultraviolet light.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is used for sealing the storage parts of envelopes, bags, boxes, etc. that store goods. The present invention also relates to a printed adhesive tape that makes it easy to detect tampering.

0002

[Conventional technology]

Conventionally, plastic films such as cellophane were used to seal storage areas such as cosmetic boxes and outer boxes. An opaque printed pressure-sensitive adhesive tape is used that has a tape support. These Te The tape may have a unique design from each company, or a film with a weak base material may be used. Or use a tape that leaves a printed surface on the adherend to ensure virginity or tamper-proofing. We are trying to stop it. However, depending on the design of the box, etc., printing adhesive may be used to hide the display surface. There are cases where the tape cannot be used. Also, barcode displays have become more common recently. When the printed adhesive tape is pasted on the barcode printing surface, the barcode is This brings about the inconvenience of not being able to read. That is, conventional printed adhesive tapes are opaque. Since the film is used as a base material, there is a defect that obscures the printed surface of the adherend. Normal transparent Bright adhesive tape does not have this problem, but it does not have tamper-evident properties. Therefore, it is not used.

0003

[Problem that the idea aims to solve]

This invention was made to improve the above-mentioned problems, and the base material of adhesive tape By using a transparent film and applying the desired printing with transparent fluorescent ink, it is possible to Even when attached to an adherend, it does not hide the print display surface of the adherend and is resistant to ultraviolet light. It also has a tamper-evident detection function by detecting the surface printed with fluorescent ink. can be done.

0004

[Means to solve the problem]

That is, the present invention forms a printed surface with transparent fluorescent ink on one side of a transparent film. , the printed surface can be detected using ultraviolet light, and it is a transparent film. and polyester, polypropylene, cellophane, vinyl chloride, and acetate. This is what I used.

[0005]

[Effect]

The printed adhesive tape of this invention is made of a transparent film as a base material, so it can be attached to an adherend. Even when the barcode is printed on the adherend without hiding the printed display surface of the adherend There is no problem in reading the code. In addition, the printing surface is formed using transparent fluorescent ink. Therefore, the printed surface can be easily detected using ultraviolet light, and it is also possible to prevent tampering and other transparent packaging. Even if it is reattached to adhesive tape, only the printed surface can be removed by exposing it to ultraviolet light. Absence is known and tampering can be easily detected.

【Example】

Hereinafter, embodiments of the present invention will be explained in detail according to the drawings. Figure 1 shows the printing of the present invention. It is an enlarged cross-sectional view of the adhesive tape, and transparent fluorescent ink is applied to one side of the transparent film 1. The desired printing surface 2 is formed, and the adhesive layer 3 is formed on the printing surface 2. It is then rolled up into a tape. This transparent film is made of polyester, polyester, Films based on lipropylene, cellophane, vinyl chloride, and acetate are used. I can stay.

[0007] Note that the transparent fluorescent ink forming the printing surface 2 is invisible under visible light and cannot be seen under ultraviolet light. You can only see it if you

[0008] Further, the base material of the tape is made of a transparent film 1, and a fluorescent dye forming a printing surface 2 is used. Since the ink also uses transparent fluorescent ink, the adhesive tape of this example is attached to the adherend 4. Even if the printed display surface 5 on the surface of the adherend 4 is readable without any problem. Ru. Moreover, even if a barcode is printed, there is no problem in optical continuity.

[0009] Next, if the adhesive tape of this example is attached to the storage part of a container such as a box, it will be illegal to use it. A person who intends to open the package may peel off the adhesive tape and use other devices to conceal the opening. When pasting transparent adhesive tape, etc., the tape itself is printed with fluorescent ink. Since surface 2 is not present, tampering can be detected immediately by ultraviolet light detection. Ru. In addition, unique characters, symbols, etc. are printed on printing side 2 to make it easier to detect unauthorized opening. Sometimes it is done.

0010

[Effect of the idea]

As mentioned above, the printed adhesive tape of the present invention has transparent fluorescent ink on one side of the transparent film. Because the printed surface is formed using a key, the printed display surface of letters, designs, etc. on the adherend surface is The seal can be sealed without causing any damage, and the printed display surface will not be obscured. Also, on the printing side Because transparent fluorescent ink is used, the package may be opened illegally and replaced with other adhesive tape. tampering can be detected immediately by exposing it to ultraviolet light. . Since the printed surface cannot be seen under visible light, it is hardly noticeable to the user and is generally not visible to the user. It has the effect of appearing like a normal transparent adhesive tape and not causing any discomfort.
