Description

Technical Field

[0001] This utility model relates to the field of laser paper technology, specifically to an anti-counterfeiting laser paper. Background Technology

[0002] Packaging paper is paper used to package various goods and materials. With the development of the packaging industry, packaging paper with anti-counterfeiting functions has gradually increased. Laser anti-counterfeiting technology includes three aspects: laser holographic image anti-counterfeiting, encrypted laser holographic image anti-counterfeiting, and laser lithography anti-counterfeiting technology. Laser holographic technology is a stereoscopic photographic technology that has developed rapidly since the advent of lasers in the 1960s.

[0003] In the prior art, Chinese patent CN215329037U discloses a double-layer laser anti-counterfeiting packaging paper, comprising a first base paper layer, an interlayer, and a second base paper layer. The first base paper layer, interlayer, and second base paper layer are arranged sequentially from top to bottom, with the interlayer forming a T-shaped cavity between them and the first and second base paper layers. A piece of paper is placed inside the cavity. While this prior art increases the anti-counterfeiting effect of the laser paper, it does not protect the first and second laser anti-counterfeiting labels from theft. Once the first and second base paper layers are forcibly torn apart and the first and second laser anti-counterfeiting labels are removed, they are easily reprocessed and reused. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-counterfeiting laser paper that can corrode the aluminum plating layer on the surfaces of the first and second base paper layers when personnel tear them to remove the first and second laser anti-counterfeiting papers for recycling, thereby destroying their metallic luster and holographic effect and preventing them from being reused.

[0005] This utility model provides the following technical solution: an anti-counterfeiting laser paper, comprising: a first base paper layer, a connecting layer, a second base paper layer, a first laser anti-counterfeiting paper, and a second laser anti-counterfeiting paper. The connecting layer is installed on one side of the first base paper layer, and the second base paper layer is installed on one side of the connecting layer. A pull-to-counterfeit mechanism is installed between the first and second base paper layers and the connecting layer. The pull-to-counterfeit mechanism includes a pull-to-move component, a scraping component, and a storage component. The pull-to-move component is used for personnel to make preliminary judgments on the anti-counterfeiting marks, and the scraping component is used to scratch the storage component to destroy the patterns on the surface of the first and second laser anti-counterfeiting papers.

[0006] As a preferred embodiment of this utility model, the cross-section of the cavity formed by the connecting layer, the first base paper layer, and the second base paper layer is T-shaped.

[0007] As a preferred embodiment of this utility model, the pulling component includes a dragging paper sheet slidably connected to the inner side of the connecting layer, and an anti-detachment sheet is installed at the other end of the dragging paper sheet. The length of the anti-detachment sheet is greater than the port length of the connecting layer, and tear marks are provided on the outer walls of the first base paper layer and the second base paper layer at positions away from the anti-detachment sheet.

[0008] As a preferred embodiment of this utility model, the first laser anti-counterfeiting paper is embedded in one end of the inside of the dragging paper, the second laser anti-counterfeiting paper is embedded in one end of the inner wall of the second base paper layer, and a transparent observation film is installed on one side of the outer wall of the first base paper layer.

[0009] As a preferred embodiment of this utility model, the scraping assembly includes connecting pieces installed on both sides of the inner walls of the first base paper layer and the second base paper layer. A first rubber sheet is installed on both sides of the connecting piece, a scraping piece is installed on the other side of the first rubber sheet, and a second rubber sheet is installed at the other end of the scraping piece.

[0010] As a preferred embodiment of this utility model, a storage membrane is installed on both sides of the inner wall of the connecting layer corresponding to the scraping blades. The cross-section of the storage membrane is annular, and a weak acid solution is stored inside the storage membrane. The weak acid solution includes, but is not limited to, citric acid.

[0011] As a preferred embodiment of this utility model, the storage film is a PSU film, and both the first and second laser anti-counterfeiting papers are transparent laser anti-counterfeiting films.

[0012] The beneficial effects of this utility model are: the pulling component allows personnel to make a preliminary judgment on the anti-counterfeiting mark, and the scraping component scratches the storage component to destroy the pattern on the surface of the first and second laser anti-counterfeiting papers. When personnel tear the first and second base paper layers and want to take out the first and second laser anti-counterfeiting papers for recycling, the aluminum plating layer on the surface of the two papers is corroded, destroying their metallic luster and holographic effect, thus preventing them from being reused.

Detailed Implementation

[0017] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0018] like Figures 1 to 3 As shown, an anti-counterfeiting laser paper includes: a first base paper layer 1, a connecting layer 2, a second base paper layer 3, a first laser anti-counterfeiting paper 4, and a second laser anti-counterfeiting paper 5. The connecting layer 2 is installed on one side of the first base paper layer 1, and the second base paper layer 3 is installed on one side of the connecting layer 2. A pull-to-counterfeit mechanism is installed between the first base paper layer 1, the second base paper layer 3, and the connecting layer 2. The pull-to-counterfeit mechanism includes a pull-to-move component, a scraping component, and a storage component. The pull-to-move component is used for personnel to initially judge the anti-counterfeiting mark, and the scraping component is used to scratch the storage component to break the anti-counterfeiting mark. The device can damage the patterns on the surfaces of the first laser anti-counterfeiting paper 4 and the second laser anti-counterfeiting paper 5. When in use, the device can allow personnel to make a preliminary judgment on the anti-counterfeiting mark by pulling the component, and the scraping component can scratch the storage component to destroy the patterns on the surfaces of the first laser anti-counterfeiting paper 4 and the second laser anti-counterfeiting paper 5. When personnel tear the first base paper layer 1 and the second base paper layer 3 to take out the first laser anti-counterfeiting paper 4 and the second laser anti-counterfeiting paper 5 for recycling, the device can corrode the aluminum plating layer on the surfaces of the two, destroying their metallic luster and holographic effect, and preventing them from being reused.

[0019] In this embodiment, the cross-section of the cavity formed by the connecting layer 2, the first base paper layer 1, and the second base paper layer 3 is T-shaped. The pulling assembly includes a dragging paper piece 6 slidably connected to the inner side of the connecting layer 2. An anti-detachment piece 7 is installed at the other end of the dragging paper piece 6. The length of the anti-detachment piece 7 is greater than the port length of the connecting layer 2. Tear marks are provided on the outer walls of the first base paper layer 1 and the second base paper layer 3 at positions away from the anti-detachment piece 7. A first laser anti-counterfeiting paper 4 is embedded in one end of the dragging paper piece 6, and a second laser anti-counterfeiting paper 5 is embedded in one end of the inner wall of the second base paper layer 3. A transparent observation film 13 is installed on one side of the outer wall of the first base paper layer 1. First, the first base paper layer 1 and the second base paper layer 3 are torn apart along the tear marks, and then pulled outwards, causing the first laser anti-counterfeiting paper 4 on the dragging paper piece 6 and the second laser anti-counterfeiting paper 5 on the second base paper layer 3 to overlap. Based on the alignment of the patterns, the staff can determine the anti-counterfeiting mark.

[0020] In this embodiment, the scraping assembly includes connecting pieces 8 installed on both sides of the inner walls of the first base paper layer 1 and the second base paper layer 3. First rubber sheets 9 are installed on both sides of the connecting pieces 8, and a scraping piece 10 is installed on the other side of the first rubber sheet 9. A second rubber sheet 11 is installed at the other end of the scraping piece 10. Storage films 12 are installed on both sides of the inner walls of the connecting layer 2 corresponding to the scraping pieces 10. The storage film 12 has an annular cross-section and stores a weak acid solution inside. The weak acid solution includes, but is not limited to, citric acid. When a person tears the first base paper layer 1 and the second base paper layer 3, the connecting pieces 8 move accordingly, pulling the first rubber sheets 9, causing the first rubber sheets 9 to deform. At this time, the scraping piece 10 moves and scrapes the surface of the storage film 12, causing the weak acid solution stored inside the storage film 12 to splash out.

[0021] In this embodiment, the storage film 12 is a PSU film, and the first laser anti-counterfeiting paper 4 and the second laser anti-counterfeiting paper 5 are both transparent laser anti-counterfeiting films. Furthermore, after the first base paper layer 1 or the second base paper layer 3 is torn open, the weak acidic solution in each storage film 12 will splash onto the surface of the first laser anti-counterfeiting paper 4 and the second laser anti-counterfeiting paper 5, causing the aluminum plating layer on the surface to be corroded, resulting in the destruction of its metallic luster and holographic effect. Even if the first laser anti-counterfeiting paper 4 and the second laser anti-counterfeiting paper 5 are removed, the integrity and display effect of the pattern after overlapping cannot be guaranteed, effectively preventing secondary use.

[0022] Implementation plan: Tear one end of the first base paper layer 1 and the second base paper layer 3 along the tear lines, then pull outwards, causing the first laser anti-counterfeiting paper 4 on the dragging paper piece 6 and the second laser anti-counterfeiting paper 5 on the second base paper layer 3 to overlap. Based on the alignment of the patterns, staff can identify the anti-counterfeiting mark. When staff tear the first base paper layer 1 and the second base paper layer 3, the connecting piece 8 will move accordingly, pulling the first rubber piece 9, which can deform accordingly. At this time, the scraping piece 10 moves accordingly and... Scratching the surface of the storage film 12 causes the weak acid solution stored inside the storage film 12 to splash out. After the first base paper layer 1 or the second base paper layer 3 is torn open, the weak acid solution inside the storage film 12 will splash onto the surface of the first laser anti-counterfeiting paper 4 and the second laser anti-counterfeiting paper 5, causing corrosion of the aluminum plating layer on its surface, resulting in damage to its metallic luster and holographic effect. Even if the first laser anti-counterfeiting paper 4 and the second laser anti-counterfeiting paper 5 are removed, the integrity and display effect of the pattern after overlapping cannot be guaranteed, effectively preventing secondary use.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
