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 can be used according to product characteristics such as important document bags, courier bags, cash bags, The sealing of court evidence bags, electronic goods, or controlled drugs can also be applied to seals such as documents, packages, cartons, drawers, safes, and car trailers.

In the case 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, and thereby 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, and the article can no longer be kept in a sealed state, which is not conducive to confidentiality.

In order to solve the above-mentioned shortcoming of the existing anti-counterfeit tape, the applicant of this case proposed a kind of anti-counterfeit tape on October 11, 1999, and it was announced on May 1, 2001, and the number of the announcement is 433279. The anti-counterfeiting adhesive tape has a printing layer printed on the back of the base material, and the 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 serve 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 object 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.

Because, the side of each layer of this anti-counterfeiting adhesive tape is all a smooth edge, and general base material selects the sheet made of plastics for use. 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.

In addition, China Taiwan Patent Publication No. M315723 New Patent proposes an easy-to-tear adhesive tape, which is applied to scotch tape, and the tape can be torn off by hand without using tools.

Because this kind of scotch tape lacks the anti-counterfeiting function of the aforementioned anti-counterfeiting tape, and cannot be used to identify the integrity of the sealed article, it cannot meet the requirements for packaging safety. In this way, the user usually has to paste the above-mentioned anti-counterfeiting tape in addition, which is still unfavorable for use.

When the anti-counterfeiting tape on the sealed article is torn off, the anti-counterfeiting tape is partially split, so as to identify the integrity of the sealed state.

In the aforementioned anti-counterfeiting adhesive tape, the tearing notch can be, for example, one of V-shaped notch, S-shaped notch, U-shaped notch, Y-shaped notch, semicircular notch, or I-shaped notch, wherein, the tearing notch is not only a concave In addition to being disposed on both sides of the base material, the identification layer, and the adhesive layer, the base material, the identification layer, and both sides of the adhesive layer can also be partially cut off.

Compared with the prior art, the utility model can be applied to anti-counterfeiting adhesive tapes of different structures, and the purpose of easily partially tearing the anti-counterfeiting adhesive tape is achieved by the tearing gap, which fully improves the convenience of users when using it. At the same time, when the anti-counterfeiting tape on the sealed article is torn off, the stress will be concentrated on the tearing gap, so that the anti-counterfeiting tape is partially split, thereby improving the ability to identify the sealed article. It can be seen from this that the application of the technology of the utility model can solve various shortcomings of the prior art and overcome the deficiencies of the prior art.

Detailed ways

The implementation of the present utility model is illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

Please refer to Fig. 1a to Fig. 2b, which are schematic diagrams of the first embodiment of the anti-counterfeiting adhesive tape 10 of the present utility model, as shown in Fig. The first identification layer 2 on one surface of 1, the second identification layer 3 partially formed on the surface of the substrate 1 on the same side as the first identification layer 2 and interlaced with the first identification layer 2, and pasted on The adhesive layer 4 on the surface of the first identification layer 2 and the second identification layer 3 opposite to the base material 1, and the adhesive layer 4 respectively arranged on the base material 1, the first identification layer 2, the second identification layer 3, and There are several tearing notches 101 on both sides of the adhesive layer 4 , through which the anti-counterfeiting adhesive tape 10 in a predetermined range can be torn off.

The substrate 1 can be, for example, a substrate made of a transparent or translucent plastic sheet material. After the substrate 1 is torn off, the identification layer displayed on the back can be easily observed. 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 the tearing state is printed on the back of the base material 1 by printing technology. The second identification layer 3 can use an ink with a color different from that of the base material 1 and the first identification layer 2 , the purpose of which is to clearly know the sealed state after the base material 1 is torn off the anti-counterfeiting adhesive tape 10 . 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 substrate 1 after it is torn off from the anti-counterfeiting adhesive tape 10. A color formed by the identification 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 10 can be pasted on the sealed article.

The tearing notches 101 are symmetrically formed on both sides of the base material 1, the first identification layer 2, the second identification layer 3, and the adhesive layer 4, and the stress is concentrated on the tearing notches by the actions of the user. 101, the local anti-counterfeiting adhesive tape 10 can be torn off at will. In this embodiment, the tearing notches 101 are recessed on both sides of the substrate 1, the first identification layer 2, the second identification layer 3, and the adhesive layer 4, so that the substrate 1, the The first identification layer 2, the second identification layer 3, and the two sides of the adhesive layer 4 form, for example, zigzag sides, and are, for example, V-shaped notches; limit.

For example, the tearing notches 101 can also be continuous S-shaped notches, U-shaped notches, Y-shaped notches, semicircular notches, I-shaped notches, or other available stress concentration on the substrate 1, the first An identification layer 2 , the second identification layer 3 , and equivalent gaps on both sides of the adhesive layer 4 . In other words, in addition to setting the tearing notches 101 on both sides of the base material 1, the first identification layer 2, the second identification layer 3, and the adhesive layer 4, it is also possible to set the cutting notches 101. The tearing notch 101 on both sides of the base material 1, the first identification layer 2, the second identification layer 3, and the adhesive layer 4; it is also possible to partially cut off the base material 1 and the first identification layer 2. , the second identification layer 3 , and the tearing notches 101 on both sides of the adhesive layer 4 . Since those skilled in the art of the anti-counterfeiting adhesive tape can understand the structure of the aforementioned tearing notch 101 and implement it accordingly, no drawings and detailed description will be made here.

As shown in Figure 2a, since the adhesion of the second identification layer 3 to the mucous layer 4a is smaller than the adhesion of the mucous layer 4a to the adhesive layer 4b and is smaller than the adhesion of the adhesive layer 4b to the sealed article , and because the adhesion of the substrate 1 to the first identification layer 2 is greater than the adhesion of the first identification layer 2 to the second identification layer 3, the adhesion of the first identification layer 2 to the second identification layer 3 The force is smaller than the adhesive force of the adhesive layer 4 to the second identification layer 3, so when the anti-counterfeiting tape is torn off, due to the difference in the size of the adhesive force, the gap between the first identification layer 2 and the first identification layer 2 Part of the second identification layer 3 will be detached 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 detached from the first identification layer 2 and left on the adhesive layer 4 on the mucosal layer 4a.

Since the mucous membrane layer 4a is still adhered to the sealed article by the action of the adhesive layer 4b, as shown in FIG. 2b, only the second identification layer 3 appears. Therefore, when viewed from top to bottom, a torn mark (such as VOID) is displayed, and it can be clearly identified that the anti-counterfeiting adhesive tape has been torn off. At the same time, due to the existence of the tearing gaps 101, when the anti-counterfeiting tape 10 on the sealed article is torn off, the anti-counterfeiting tape 10 can be partially split, thereby identifying the integrity of the sealing state and improving the identification effect.

Fig. 3 to Fig. 5 are the schematic diagrams of the second embodiment of the anti-counterfeiting adhesive tape of the present utility model, as shown in Fig. The printing layer 12 on the back side of the base material 11 as the identification layer, the gap 20 formed in the printing layer 12, the fixed color layer 13 coated in the printing layer 12 and the gap 20 as the identification layer, and the fixed color layer 13 coated on the fixed color layer. The non-release layer 14 on the layer 13, 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 and the printing layer 12 respectively , the fixed color layer 13, the non-release layer 14, the adhesive layer 15, and several tearing notches 101 on both sides of the release paper 16 (as shown in FIG. 5 ).

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 the present embodiment, the printed layer 12, as shown in FIG. 4, can display the words, patterns, marks, etc. of "opened", "VOID", etc., and the fixed color layer 13 adopts the color and substrate 11 and The printing layer 12 is composed of inks with appropriate differences, so as to show the clarity of the anti-tear effect. For example, when desiring to make people clearly aware of the anti-tearing effect, the color contrast of the fixed color layer 13 and the base material 11 and the printing layer 12 can be darker; shallow.

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 substrate 11, and when it is coated on the printed layer 12, except for the words and patterns of the printed layer 12 , marks, etc., the back of the substrate 11 without the printed layer 12 and the space 20 between the printed layers 12 are all coated with the fixed color layer 13. When the anti-counterfeiting tape is torn off, the fixed 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 surface of the substrate 11 is seen to be separated from the fixed color layer 13. 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 the anti-counterfeiting tape is torn off. material as the adhesive layer.

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 4, 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 base material 11 are still in close contact. Therefore, viewed from the surface of the base material 11, as shown in FIG. 4 and FIG.

At this time, even if the torn anti-counterfeiting tape is attached back to the sealed article A (as shown in Figure 5), to cover up the fact that it is torn or make it continue to be sealed by the anti-counterfeiting tape, it has been torn The opening mark B will still be displayed on the surface of the substrate 11 , and cannot return to the state before being torn off, and the anti-counterfeiting tape can be partially torn through the tearing notches 101 .

The biggest difference between the second embodiment and the first embodiment is that the tearing gap 101 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 tape on both sides of the anti-adhesive paper 16 ; in other words, even the anti-counterfeit tapes with different structures can also be provided with the tearing gaps 101 .

In addition, FIG. 6 to FIG. 8b are schematic diagrams of the third embodiment of the anti-counterfeiting adhesive tape according to 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 6, the anti-counterfeit adhesive tape of the third embodiment comprises: base material 11; The printing layer 12 as identification layer; The space 20 that is formed in this printing layer 12; As the fixing color layer 13 of identification layer; Adhesive layer, comprises The mucous membrane layer 14a and the adhesive layer 15a; and several tearing gaps 101 (as shown in Figure 8a and Figure 8b ), are respectively arranged on the substrate 11, the printing layer 12, the fixed color layer 13, and the adhesive both sides of the layer.

It should be noted that, 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; However, in the third embodiment, there is no non-release layer 14, and the adhesive force of the printing layer 12 to the fixed color layer 13 is smaller than that of the mucous membrane layer 14a to the fixed color layer 13, and is also smaller than that of the substrate 11 to the printed layer 12. The adhesion force of the base material 11 to the fixed color layer 13 is greater than the adhesion force of the mucous membrane layer 14a to the fixed color layer 13.

In this way, if the anti-counterfeiting tape is torn off, as shown in Figure 7, the force of the adhesive layer 15a on the sealed article A acts on the fixed color layer 13 through the mucous membrane layer 14a, 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 relationship 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 remain 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 8a, 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 Looking down from the top, the torn mark B such as the torn words, patterns or marks is displayed, and it can be clearly distinguished that the anti-counterfeiting tape has been torn off. As shown in FIG. 8 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. 8 a on the surface of the base material 11 . At the same time, since the tearing notches 101 can concentrate the stress, the anti-counterfeiting tape will be partially torn as shown in FIG. 8a and FIG. 8b when the anti-counterfeiting tape is torn off.

Compared with the existing anti-counterfeiting tape, the anti-counterfeiting tape of the utility model is designed to be formed on the tearing gaps on the sides of each layer of the anti-counterfeiting tape, which can tear the anti-counterfeiting tape to a predetermined length, eliminating the need to use tools to cut the existing anti-counterfeiting tape the inconvenience. At the same time, the tearing notch can concentrate stress, and when the anti-counterfeiting tape is torn off, the tearing notch can also make the anti-counterfeiting tape partly split, so as to provide the function of identifying the sealed article. It can be seen from the above that the anti-counterfeiting adhesive tape of the present utility model has fully improved the existing shortcomings, 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.
