Description

Easy-to-identify anti-counterfeiting adhesive structure

The present invention relates to packaging structure, especially to quality assurance and anti-counterfeiting packaging structure.

For example, Taiwan application No. 73210112 "Self-destruction protection label structure", Taiwan application No. 74206279 "Self-destruction protection tape structure" patent, Taiwan application No. 833106546 "Making trademark paper signature and its products" patent and Taiwan application No. As stated in the No. 87106327 "Method for Making Security Paper Labels" and other patents, it mainly discloses a protective tape or protective label. The protective tape or protective label does not display the pattern, pattern or text when it is originally sealed, and when the protective tape or When the protective label is torn and damaged, a display pattern, pattern or text will appear, which means that the protective tape or protective label has been destroyed. The displayed pattern, pattern or text can be used as a warning, promotional text or advertising slogan. Enhance the sense of commodity value and meet the needs of commercial sales.

However, although the conventional protective tape or protective label can be used as a basis for opening or not by displaying patterns, patterns or text, in fact, after opening, it may be restored to an almost unopened state by re-gluing. For those who are not familiar with its packaging structure, it is almost difficult to identify whether it has been opened, which may cause the goods in the box to be packaged and damaged, which cannot meet the requirements of quality assurance and anti-counterfeiting.

Therefore, such as Taiwan Announcement No. M418789 "Quality Assurance Anti-counterfeiting Adhesive Structure", it uses the fragile layer to be torn (removed) and will break (fragment) irreversibly, forming an unrecoverable and easily recognizable text that can be displayed The anti-counterfeiting paste structure. However, the adhesive has the characteristics of high temperature degumming. This conventional quality assurance anti-counterfeiting adhesive structure uses high temperature to make the adhesive layer fail. It may be removed without damaging the fragile layer, and it can still return to It is almost unopened, and it is difficult to tell whether it has been opened.

The main purpose of the present invention is to expose an easily recognizable anti-counterfeiting adhesive structure, which will change color at high temperature and cannot be restored to avoid the possibility of degumming at high temperature and returning to its original shape.

Based on the above objective, the present invention is an easy-to-identify anti-counterfeiting adhesive structure, which includes a sheet and a thermochromic coating formed in the sheet. The sheet includes a substrate layer, an anti-counterfeiting layer, and a fragile layer. And an adhesive layer, wherein the base layer and the fragile layer are adhered to both sides of the anti-counterfeiting layer, the anti-counterfeiting layer includes a first pattern and a second pattern, and the first pattern sticks to the base layer Is greater than the adhesive force of pasting the fragile layer, and the adhesive force of the second pattern pasting the fragile layer is greater than the adhesive force of pasting the substrate layer, and one side of the adhesive layer is pasted to the fragile layer away from the anti-counterfeiting layer And the thermochromic coating is an irreversible ink coating.

According to this, after the adhesive layer of the present creation is pasted to close a box, when the box is to be opened, the fragile layer will be destroyed after the substrate layer is first torn off; and the substrate layer is torn off. When the anti-counterfeiting layer has a different adhesive force, the first pattern and the second pattern will stick to the base layer and the fragile layer, respectively, and the patterns can be displayed according to the first pattern and the second pattern. Patterns or text; and the temperature-sensitive color-changing coating can ensure that high temperature cannot be used to make the adhesive layer fail and repeat pasting. Therefore, at the same time, it is combined with the non-recoverable characteristics of the fragile layer that the fragile layer is torn (removed), the anti-counterfeiting layer exhibits a pattern, and the thermochromic coating ensures that the adhesive layer does not use high temperature to make the adhesive layer fail and repeat. The pasting condition can strengthen the quality assurance and anti-counterfeiting effect to meet the needs of use.

With regard to the detailed content and technical description of the present invention, examples are used for further explanation. However, it should be understood that these examples are for illustrative purposes only and should not be interpreted as limitations to the implementation of the present invention.

Please refer to "Figure 1" for the first embodiment. The present invention is an easy-to-identify anti-counterfeiting adhesive structure 20. The easy-to-identify anti-counterfeiting adhesive structure 20 includes a piece 30 and a temperature-sensitive discoloration formed in the piece 30 Coating 40, the sheet 30 includes a base material layer 31, a fragile layer 32, an anti-counterfeiting layer 33, an adhesive layer 34, and a release-treated substrate 35, wherein the two sides of the anti-counterfeiting layer 33 are respectively pasted The base material layer 31 and the fragile layer 32, the anti-counterfeiting layer 33 includes a first pattern 331 and a second pattern 332, and the first pattern 331 and the second pattern 332 can be arranged alternately, which allows the A pattern 331 and the second pattern 332 form a specific and complementary pattern, pattern or text.

Moreover, the adhesion of the first pattern 331 to the base layer 31 is greater than the adhesion of the fragile layer 32, and the adhesion of the second pattern 332 to the fragile layer 32 is greater than the adhesion of the base layer 31 In addition, one side of the adhesive layer 34 is attached to the side of the fragile layer 32 away from the anti-counterfeiting layer 33, and the other side of the adhesive layer 34 is attached to the substrate 35. In this embodiment, the thermochromic coating 40 can be formed between the adhesive layer 34 and the fragile layer 32, the thermochromic coating 40 is an irreversible ink coating, and the color change temperature can be adjusted to about 60 ℃ around.

Please also refer to "FIG. 2". When the base layer 31 is torn off, the first pattern 331 and the second pattern 332 will stick to the base layer 31 and the base layer 31 due to different adhesive forces. The fragile layer 32 is on.

Please refer to "Figure 3A" ~ "Figure 3C" together. It is a schematic diagram of the creation and for the convenience of drawing. The drawing scale of "Figure 3A" ~ "Figure 3C" is virtual and does not represent actual implementation. proportion. Since the substrate 35 of the easy-to-identify anti-counterfeit adhesive structure 20 has undergone a release process, the adhesive layer 34 can be repeatedly adhered to the substrate 35. Therefore, the easy-to-identify anti-counterfeit adhesive structure 20 is normally stored If the substrate 35 is attached, when it is to be used, the adhesive layer 34 is separated from the substrate 35 and adhered to a box 50 (such as "FIG. 3A").

When the box 50 is to be opened, the base layer 31 is torn off first, so the first pattern 331 and the second pattern 332 will stick to the base layer 31 and the fragile layer 32, respectively. On the base layer 31 and the fragile layer 32, patterns, patterns or characters (such as "FIG. 3B") appear respectively.

Then opening the box 50 will destroy the fragile layer 32 (such as "FIG. 3C"). After the fragile layer 32 is destroyed, it cannot be restored. At this time, even if the substrate layer 31 is carefully glued back The fragile layer 32 cannot be restored to its original state. In addition, the thermochromic coating 40 changes its color after being heated and is irreversible. Therefore, the thermochromic coating 40 can ensure that the adhesive layer 34 cannot be repeatedly pasted due to the failure of the adhesive layer 34 at high temperature. In other words, it can be determined whether the box 50 has been opened by observing whether the fragile layer 32 is damaged and whether the color of the thermochromic coating 40 changes.

Please refer to "FIG. 4" again, which is another implementation of the first embodiment of the creation. The surface of the substrate layer 31 can be subjected to release treatment and can be repeatedly pasted. One side of the adhesive layer 34 is pasted On the side of the fragile layer 32 away from the anti-counterfeiting layer 33, and the other side of the adhesive layer 34 can be directly adhered to the substrate layer 31, so that the easily recognizable anti-counterfeiting adhesive structure 20 (that is, the substrate layer 31. The anti-counterfeiting layer 33, the fragile layer 32, the thermochromic coating 40 and the adhesive layer 34) are wound to form a tape shape, so that they can be used like ordinary tapes, which can increase the convenience of use.

Please refer to FIG. 5 again, which is a second embodiment. In this embodiment, the thermochromic coating 40 can also be formed on the surface of the substrate layer 31.

Please refer to FIG. 6 again, which is a third embodiment. In this embodiment, the thermochromic coating 40 may also be formed between the fragile layer 32 and the anti-counterfeiting layer 33.

Please refer to FIG. 7 again, which is a fourth embodiment. In this embodiment, the thermochromic coating 40 can also be mixed with the fragile layer 32.

Please refer to FIG. 8 again, which is a fifth embodiment. In this embodiment, the thermochromic coating 40 can also be mixed with the adhesive layer 34.

As mentioned above, the characteristics of this creation include at least:

1. Patterns, patterns or text can be displayed on the substrate layer and the fragile layer respectively, which can enhance the sense of value, and the substrate layer can cover sheet or roll materials, such as cloth, paper, metal, plastic ……and many more.

2. The fragile layer is made of a material that can be broken (fragmented) by tearing off (removing) and has the property of irreversibility.

3. The thermochromic coating can change color when heated, which can ensure that high temperature can not be used to make the adhesive layer fail and repeat pasting.

Therefore, this creation can not only show patterns, patterns or texts, but also cooperate with the non-recoverable characteristics of the fragile layer and the non-recoverable characteristics of the thermochromic coating when it is heated to enhance the quality assurance and anti-counterfeiting effect. Meet the needs of use.
