Description

Security tape

technical field

The utility model relates to an anti-counterfeiting adhesive tape, in particular to an anti-counterfeiting adhesive tape which is easy to tear off in a predetermined range.

Background technique

With the development of high technology and the improvement of consumers' requirements for packaging safety, anti-counterfeit paper, anti-counterfeit film, and anti-counterfeit tape with anti-counterfeiting functions can be applied to important document bags, courier bags, cash bags, courts, etc. according to product characteristics. Evidence bags, electronic products, or the sealing of controlled drugs can also be used for sealing documents, packages, cartons, drawers, safes, car trailers, etc.

In terms of anti-counterfeiting tape, at least one layer of paint is applied on the back of the tape as an identification layer with anti-counterfeiting marks, and an adhesive is applied on the identification layer as an adhesive layer to complete the sealing of the anti-counterfeiting tape. on the item.

At the same time, since the adhesion between the identification layer and the adhesive layer is greater than the adhesion between the identification layer and the base material, after the article is torn off the base material of the anti-counterfeiting tape, the anti-counterfeiting mark on the identification layer can be retained. On the sealed item to identify the integrity of the sealed state.

However, after the existing anti-counterfeiting adhesive tape is torn off the base material, the sealed seal loses its integrity immediately, so the article can no longer be kept in a sealed state and is not conducive to confidentiality.

In order to solve the above-mentioned shortcoming of the existing anti-counterfeiting tape, the applicant of this case proposed a kind of anti-counterfeiting tape to Taiwan, China on October 11, 1999, and announced it on May 1, 2001, with the announcement number 433279. The anti-counterfeiting adhesive tape is printed with a printing layer on the back of the base material, and a fixed color layer is coated on the printing layer and the parts without the printing layer on the base material. The printing layer and the fixed color layer are used as an identification layer with anti-counterfeit marks, and the fixed color layer is sequentially formed with a mucous layer and an adhesive layer as an adhesive layer, so that the anti-counterfeit tape can be pasted on the article to be sealed .

The adhesion of the printing layer to the fixed color layer is less than the adhesion of the mucous layer to the fixed color layer, and the adhesion of the printing layer to the fixed color layer is also smaller than the adhesion of the substrate to the printing layer, and the The adhesive force of the base material to the fixed color layer is greater than the adhesive force of the mucous layer to the fixed color layer. Therefore, the anti-counterfeiting adhesive tape can clearly show the sealing state, and even if the base material is torn off, the mucous layer is still adhered to the sealed object, so the sealing can be maintained.

The sides of each layer of the anti-counterfeiting adhesive tape are smooth edges, and the general base material is a thin sheet made of plastic. In this way, when the user wants to separate part of the anti-counterfeit tape from the rolled film, he needs to use scissors or similar cutting tools to achieve the purpose of cutting, so it is quite inconvenient to use.

At the same time, after sealing, in order to maintain the integrity of the seal, the sealed article cannot be opened at will to obtain the information of the article, so it is easy to cause confusion for the user. In this way, the user usually has to paste additional paper with information about the sealed article, which is time-consuming and laborious, and if there is no space for pasting the sealed article with paper, this method cannot be used to solve the problem, which is not conducive to use.

Therefore, it can be seen from the above that the existing anti-counterfeiting adhesive tapes obviously still have inconveniences and deficiencies in actual use, and there are still areas to be improved.

Please refer to Figures 1 to 3, which are schematic diagrams drawn by the first embodiment of the anti-counterfeiting adhesive tape of the present invention, as shown in Figure 1, the anti-counterfeiting adhesive tape of this embodiment is applied to sealed items for identifying the integrity of the sealed state , and may include a base material 1, a first identification layer 2 partially formed on a surface of the base material 1, a part formed on the surface of the base material 1 on the same side as the first identification layer 2 and connected to the first identification layer The second identification layer 3 with layers 2 staggered, the adhesive layer 4 attached to the surface of the first identification layer 2 and the second identification layer 3 opposite to the substrate 1, and the correspondingly arranged on the substrate at predetermined intervals 1. Several tear lines 5 between the first identification layer 2 , the second identification layer 3 , and the adhesive layer 4 (only one tear line 5 is shown here).

The aforementioned base material 1 is made of, for example, a transparent or translucent plastic sheet material. After the base material 1 is torn off, the identification layer displayed on the back side can be observed conveniently.

The first identification layer 2 is a resin material with the same color and transparency as the aforementioned base material 1 and has adhesiveness with the base material 1 , and a mark for identifying a tearing state is printed on the back of the base material 1 by printing technology.

The second identification layer 3 can use ink of any color different from that of the base material 1 and the first identification layer 2, the purpose of which is to clearly know the sealing state after the base material 1 is torn off the anti-counterfeit tape. Wherein, a digital visual identification part 6 may be provided on the second identification layer 3 to facilitate identification when sealing the article.

As shown in Figure 2a, there is a viewing identification part 6 arranged on the second identification layer 3 between every two tearing lines 5, but in other embodiments, the viewing section 6 can also be arranged at intervals of more than one tearing line 5. Visual recognition unit 6. In this embodiment, the viewing identification part 6 is formed by cutting out part of the second identification layer 3, but it is not limited thereto, and the viewing identification part 6 can be, for example, a serial number for users to identify The information of the sealed article, such as the numbered box of the sealed article, but it is not limited to this; Patterns, characters, or equivalent signs of "dishes", "confidential documents", etc., the user can know what the sealed article is when seeing the visual identification part 6.

Certainly, the visual identification part 6 can also be arranged in other layers of the anti-counterfeiting adhesive tape. For example, as shown in FIG. 3 , it is also possible to excavate part of the base material 1 as the visual identification part 6, and the visual identification part 6 can also be a pattern, a text, or an equivalent displaying information of the sealed article. marked. Wherein, it is possible to choose not to coat any color on the visual identification part 6 , but to present only the color of the base material 1 , but not limited thereto.

In other words, the visual identification part 6 can be selected to be arranged on any layer of the base material 1, the first identification layer 2, and the second identification layer 3, as long as the visual identification part 6 can be seen by the user. Just know what the sealed item is. Of course, the visual identification part 6 can also be provided on each layer of the base material 1, the first identification layer 2, and the second identification layer 3, rather than being limited to what is described in this embodiment. And because the technology of setting the viewing identification portion 6 on each layer/any layer of the base material 1, the first identification layer 2, and the second identification layer 3 is a person with ordinary knowledge in the technical field It can be understood and implemented accordingly, so no further explanation will be given here.

The adhesive layer 4 may include a mucous layer 4a and an adhesive layer 4b, wherein the mucous layer 4a is made of an adhesive film, and its function is to fix the first identification after the substrate 1 is torn off from the anti-counterfeiting tape. The color formed by the layer 2 can be adhered to the sealed article by the mucous layer 4a. The adhesive layer 4b is coated on the adhesive layer 4a with, for example, an adhesive, so that the anti-counterfeiting adhesive tape can be pasted on the sealed article.

Since the adhesive force of the second identification layer 3 to the mucous layer 4a is smaller than the adhesive force of the mucous layer 4a to the adhesive layer 4b and is smaller than the adhesive force of the adhesive layer 4b to the sealed article, and because the substrate 1 The adhesion force to the first identification layer 2 is greater than the adhesion force of the first identification layer 2 to the second identification layer 3, and the adhesion force of the first identification layer 2 to the second identification layer 3 is smaller than that of the adhesive layer 4 The adhesive force of the second identification layer 3, so as shown in Figure 2b, when the anti-counterfeiting tape is torn off, due to the difference in the size of the adhesive force, the first identification layer 2 and the first identification layer 2 in the gap Part of the second identification layer 3 will be separated from the anti-counterfeiting adhesive tape along with the substrate 1, and the second identification layer 3 originally located on the first identification layer 2 will be separated from the first identification layer 2 and left on the adhesive layer 4. On the mucous membrane layer 4a, wherein, the mucous membrane layer 4a is still adhered to the sealed article by the action of the adhesive layer 4b, and only presents the second identification layer 3 (as shown in Figure 2a), so from top to bottom When viewed from below, a torn mark (such as VOID) is displayed, and it can be clearly identified that the anti-counterfeiting tape has been torn off.

Please refer to FIG. 2a again, the tearing line 5 can be formed by spaced perforations perpendicular to the anti-counterfeiting adhesive tape and arranged linearly. In this way, as shown in FIG. 3 , the anti-counterfeit adhesive tape of a predetermined length can be partially torn by the tearing line 5 . Certainly, this tearing line 5 also can for example be perpendicular to the linear embossing of this anti-counterfeiting tape, linear groove, linear pit, linear indentation, linear embossing or other equivalent structures that can tear this anti-counterfeiting adhesive tape, and Not limited to what is described in this example.

Fig. 4 to Fig. 6 are the schematic diagrams drawn by the second embodiment of the anti-counterfeiting adhesive tape of the present utility model, as shown in Fig. 4, the anti-counterfeiting adhesive tape of this embodiment comprises: a substrate 11 made of transparent or translucent plastic sheet, The printed layer 12 printed on the back side of the substrate 11, the void 20 formed in the printed layer 12, the fixed color layer 13 coated on the printed layer 12 and the gap 20 as a discrimination layer, and coated on the fixed color layer 13, the non-release layer 14 on the surface of the non-release layer 14, the adhesive layer 15 coated on the surface of the non-release layer 14, the release paper 16 pasted on the adhesive layer 15, and the base material 11, the printing Layer 12, the fixed color layer 13, the non-release layer 14, the adhesive layer 15, and several tear lines 5 of the release paper 16.

The base material 11 can be made of any material suitable for making an adhesive tape to provide a sealing effect, and the shape is not limited, such as rectangle, ellipse, strip or other suitable shapes. In this embodiment, the base material 11 is transparent or translucent, and the tearing marks shown by the printed layer 12 on the back can be observed from the surface.

The printing layer 12 is printed on the back of the substrate 11 by any printing technique from a resin material having the same color and transparency as the substrate 11 and having adhesiveness with the substrate 11 . In this embodiment, the printed layer 12 is used as an identification layer, for example as shown in FIG. 6 , which can display the words "opened", "VOID", patterns, marks and other tear marks.

The color-fixed layer 13 is also used as an identification layer, which can be made of inks whose colors are appropriately different from those of the base material 11 and the printing layer 12, so as to show the clarity of the anti-tear effect. For example, if people want to clearly know the anti-tear effect, the color contrast with the substrate 11 and the printing layer 12 can be darker; if it is desired to make it difficult for outsiders to notice the anti-tear effect, the color contrast can be lighter. Furthermore, the adhesive force between the fixed color layer 13 and the printing layer 12 is smaller than the adhesive force between the fixed color layer 13 and the back of the base material 11, and when it is applied on the printed layer 12, except for the words and patterns of the printed layer 12 , marks, etc., the back of the base material 11 without the position of the printing layer 12 and the space 20 between the printing layers 12 are all coated with the fixed color layer 13. When the base material 11 is torn apart, the fixing color layer 13 The color layer 13 is separated from the printing layer 12, but is still adhered to the back of the substrate 11, so that the fixed color layer 13 can be used as a background color for comparison, and the color layer 13 separated from the fixed color layer 13 can be seen from the surface of the substrate 11. Printing layer 12.

The non-release layer 14 is coated between the fixed color layer 13 and the adhesive layer 15, as a medium material, which can make the ink of the fixed color layer 13 suitable for coating glue to form the adhesive layer 15, The adhesive layer 15 and the color-fixing layer 13 are combined with strong adhesive force. The adhesive layer 15 is used for sticking the anti-counterfeiting tape on the sealed article. It is preferable to adopt a kind of anti-counterfeiting adhesive tape that will not stick to the sealed article and can be pasted on the sealed article after tearing off the anti-counterfeiting tape. material as the adhesive layer 15.

The anti-adhesive paper 16 can be, for example, existing benchmark paper. When in use, the anti-adhesive paper 16 is torn off first, and then the anti-counterfeit tape is pasted on the sealed article. If the anti-counterfeiting tape is torn off, as shown in Figure 5, the adhesive force of the adhesive layer 15 to the sealed article A acts on the fixed color layer 13 through the non-tearable layer 14, so that the fixed color layer 13 simultaneously The printing layer 12 and the substrate 11 have a detachment force; however, since the fixed color layer 13 is more adhesive to the substrate 11 than the printing layer 12, the fixed color layer 13 and the The printing layers 12 are pulled apart to form a gap 21 , while the color-fixing layer 13 and the substrate 11 are still in close contact. Therefore, viewed from the surface of the base material 11, as shown in FIG. Now, even if the anti-counterfeiting tape that has been torn off is pasted back on the sealed article A (as shown in Figure 5), to conceal the fact that it is torn or to continue to have the effect of anti-counterfeiting tape sealing, but due to the When the gap 21 is formed, the torn mark B will still be displayed on the surface of the base material 11, and cannot return to the state before being torn off.

The biggest difference between the second embodiment and the first embodiment is that the tear line 5 in the second embodiment is correspondingly arranged on the base material 11, the printing layer 12, the fixed color layer 13, the non-release layer 14, The adhesive layer 15 and the anti-counterfeit adhesive tape of the anti-adhesive paper 16; that is to say, even anti-counterfeit adhesive tapes with different structures can also be provided with the tear line 5.

In addition, in the second embodiment, the visual identification part 6 can also be provided, for example, on the outer surface of the base material 11 . For example, the visual identification part 6 can be printed on the outer surface of the base material 11 by printing to provide information to be known, such as serial number, shipping address, and the like. Of course, the visual recognition part 6 can also be arranged in other layers, as long as it can be recognized by the user.

7 to 9b are schematic diagrams of the third embodiment of the anti-counterfeiting adhesive tape of the present invention, wherein the parts that are the same as those of the second embodiment are represented by the same component symbols, and detailed descriptions are omitted.

As shown in Figure 7, the anti-counterfeiting adhesive tape of the third embodiment also includes: a substrate 11; a printing layer 12 as an identification layer; a gap 20 formed in the printing layer 12; a fixed color layer 13 as an identification layer; an adhesive layer, It includes a mucous membrane layer 14a and an adhesive layer 15a; a number of tear lines 5 corresponding to the base material 11, the printing layer 12, the fixed color layer 13, and the adhesive layer at predetermined intervals; and a visual identification part 6. But, in the second embodiment, the adhesion force of the adhesive layer 15a to the fixed color layer 13 is greater than the adhesion force of the fixed color layer 13 to the printing layer 12, but less than the adhesion force of the fixed color layer 13 to the substrate 11; and the third In the embodiment, there is no such non-release layer 14, and the adhesion force of the printing layer 12 to the fixed color layer 13 is smaller than the adhesion force of the mucous membrane layer 14a to the fixed color layer 13, and is also smaller than the adhesion force of the substrate 11 to the printing layer 12, And the adhesive force of the substrate 11 to the fixed color layer 13 is greater than the adhesive force of the mucous membrane layer 14 a to the fixed color layer 13 .

In this way, if the anti-counterfeiting tape is torn off, as shown in Figure 8, the adhesive layer 15a acts on the fixed color layer 13 through the mucous membrane layer 14a to the sealed article A, so that the fixed color layer 13 acts on the base. Material 11 produces the active force of detachment; And because the adhesive force of base material 11 to printing layer 12 is greater than the adhesive force of printing layer 12 to the fixed color layer 13 part on printing layer 12, printing layer 12 fixes color to this part again The adhesive force of layer 13 is less than the adhesive force of mucous membrane layer 14a to the fixed color layer 13 of this part, based on the size difference relation of this kind of adhesive force, this printing layer 12 and the fixed color layer 13 part in its space 20 (that is, The fixed color layer 13 is scheduled to be separated from the part of the mucous membrane layer 14a) along with the substrate 11 from the anti-counterfeiting adhesive tape, and the fixed color layer 13 on the original printing layer 12 will be separated from the printing layer 12 and left on the mucous membrane layer 14a, the mucous membrane The layer 14a is still stuck on the sealed article A by the effect of the adhesive layer 15a.

As shown in Figure 9a, the fixed color layer 13 pasted on the mucous membrane layer 14a of the sealed article A, because only the part of the fixed color layer 13 coated on the original printing layer 12 remains, so the mucous membrane layer 14a When viewed from above, the torn marks B such as torn words, patterns or marks are displayed, and it can be clearly distinguished that the anti-counterfeiting adhesive tape has been torn off. As shown in FIG. 9 b , the portion of the fixing color layer 13 in the void 20 of the printing layer 12 that is torn off with the base material 11 presents a reverse tearing mark C opposite to that of FIG. 9 a on the surface of the base material 11 .

Please refer to Fig. 7 again, the tear line 5 can be formed by perforations perpendicular to the anti-counterfeiting adhesive tape and arranged linearly at intervals, and the visual recognition part 6 can be formed on the fixed color layer 13 for example to be separated from the mucous membrane layer 14a part. Of course, the visual identification part 6 can also be arranged, for example, on the part where the fixed color layer 13 will not break away from the mucous membrane layer 14a, the mucous membrane layer 14a, or the adhesive layer 15a; The information of the sealed article A can be obtained by observing the mucous membrane layer 14a.

Compared with the existing anti-counterfeiting tape, the anti-counterfeiting tape of the utility model is designed to be formed on the tear line of each layer of the anti-counterfeiting tape, which can tear the anti-counterfeiting tape to a predetermined length, eliminating the inconvenience of using tools to cut the existing anti-counterfeiting tape . At the same time, the anti-counterfeit adhesive tape is provided with a visual identification part to provide the function of identifying sealed items. It can be seen from the above that the anti-counterfeiting adhesive tape of the present utility model has fully improved the shortcomings of the prior art, and has a high industrial application value.

Of course, the utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but These corresponding changes and deformations should all belong to the protection scope of the appended claims of the present utility model.
