Description

Technical Field

[0001] The utility model relates to the technical field of anti-counterfeiting packaging, in particular to a reverse upward-lighting packaging box with an anti-counterfeiting function. Background Art

[0002] The reverse glazing process can form a matte effect of frosted surface through the cohesive reaction of UV primer and UV varnish, allowing the high gloss effect of mirror surface and matte effect to exist on the same printed product at the same time, forming a stronger contrast in brightness and achieving better glazing effect.

[0003] The surface light and dark contrast brought by the reverse upward glazing process has a unique visual effect, which is beautiful and not easy to imitate. It has been applied to the packaging of cosmetics, tobacco and alcohol industries and to anti-counterfeiting identification. However, the application of the reverse upward glazing process in packaging anti-counterfeiting identification is still relatively rudimentary, mainly relying on its own high gloss and matte visual contrast effects and the complexity of its own process for anti-counterfeiting. The correlation with other anti-counterfeiting technologies is poor, and a tightly integrated anti-counterfeiting system has not been formed. In the face of increasingly sophisticated counterfeiting methods, it is insufficient and can be easily disassembled and imitated one by one.

[0004] Based on this, it is necessary to study a reverse glossy packaging box with anti-counterfeiting function. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a reverse-glossy packaging box with anti-counterfeiting function, which can effectively solve the problem that the reverse-glossy process is poorly correlated with other anti-counterfeiting technologies in packaging anti-counterfeiting identification and is easily disassembled and imitated.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A reverse glossy packaging box with anti-counterfeiting function, comprising a paper base and an ink layer arranged on the paper base, the ink layer having a basic pattern, and further comprising a UV primer layer, a UV glossy layer, a first photochromic layer and an invisible ink layer;

[0008] The UV primer layer is partially arranged on the ink layer; the UV varnish layer is entirely arranged on the ink layer and the UV primer layer;

[0009] The overlapping part of the UV primer layer and the UV varnish layer forms a matte area, and the non-overlapping part of the UV primer layer and the UV varnish layer forms a highlight area;

[0010] A first photochromic layer is provided in the matte area, the first photochromic layer is distributed between the ink layer and the UV primer layer, and a photochromic pattern is provided on the first photochromic layer; the first photochromic layer can change color under ultraviolet irradiation;

[0011] An invisible ink layer is arranged in the highlight area, the invisible ink layer is partially arranged between the ink layer and the UV varnish layer, an invisible pattern is arranged on the invisible ink layer, and the invisible ink layer and the invisible pattern are visible only under ultraviolet irradiation.

[0012] Furthermore, the ink layer and the basic pattern completely cover the paper base layer;

[0013] The photochromic pattern and the invisible pattern are partially covered on the basic pattern;

[0014] The photochromic pattern and the basic pattern are combined to form an appearance pattern under natural light; the photochromic pattern, the basic pattern and the invisible pattern are combined to form an anti-counterfeiting pattern under ultraviolet light.

[0015] Furthermore, the anti-counterfeiting pattern includes an anti-counterfeiting information QR code.

[0016] Furthermore, a second photochromic layer is provided in the highlight area, the second photochromic layer is partially provided between the ink layer and the UV varnish layer, and the second photochromic layer and the invisible ink layer are arranged alternately.

[0017] Furthermore, a transparent protective layer is arranged on the ink layer, and the first photochromic layer and the invisible ink layer are both arranged on the transparent protective layer.

[0018] The beneficial effects of the above technical solution are:

[0019] The utility model utilizes a reverse glazing process to form a matte area and a highlight area at the overlapping and non-overlapping parts of the UV primer layer and the UV varnish layer, respectively; the first photochromic layer is located in the matte area, and the low reflection property of the matte area is utilized to enhance the intuitiveness and visibility of the color change; the invisible ink layer is located in the highlight area, and the reflection property of the highlight area is utilized to enhance the fluorescent appearance effect of the invisible pattern under ultraviolet irradiation, thereby being able to produce a special visual effect different from the conventional glazing process. During anti-counterfeiting identification, first the difference in visual effects between the matte area and the highlight area brought about by the reverse glazing process itself can be used as an anti-counterfeiting standard; then, whether the photochromic pattern and the invisible pattern appear smoothly under ultraviolet light is used as the second anti-counterfeiting standard; finally, under ultraviolet light, the special visual effects of the first photochromic layer in the matte area and the invisible ink layer in the highlight area are used as the third anti-counterfeiting standard; this creates a close technical connection between the reverse glazing process and the photochromic anti-counterfeiting technology and the invisible ink anti-counterfeiting technology, which can not only further enhance the effects of the photochromic anti-counterfeiting technology and the invisible ink anti-counterfeiting technology, but also combine to produce new anti-counterfeiting identification standards, solving the problem that the reverse glazing process is poorly correlated with other anti-counterfeiting technologies in packaging anti-counterfeiting identification and is easily split and imitated, increases the correlation between the reverse glazing process and the photochromic anti-counterfeiting technology and the invisible anti-counterfeiting technology, forms a complete anti-counterfeiting system, and enhances the reliability of anti-counterfeiting identification.

[0020] Figure 1 This is a cross-sectional view of the printing structure of the packaging box.

[0021] Figure numerals: 1 is a paper base layer, 2 is an ink layer, 3 is a UV primer layer, 4 is a UV varnish layer, 5 is a first photochromic layer, 6 is an invisible ink layer, 7 is a second photochromic layer, and 8 is a transparent protective layer. DETAILED DESCRIPTION

[0022] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0023] The present embodiment aims to provide a reverse upward-glazing packaging box with anti-counterfeiting function, which is mainly used for anti-counterfeiting of cigarette packaging boxes, and aims to solve the problem that the reverse upward-glazing process is poorly correlated with other anti-counterfeiting technologies in packaging anti-counterfeiting identification and is easily disassembled and imitated.

[0024] A reverse glossy packaging box with anti-counterfeiting function comprises a paper base layer 1 and an ink layer 2 printed on the paper base layer 1, wherein the ink layer 2 has a basic pattern and further comprises a UV primer layer 3, a UV glossy layer 4, a first photochromic layer 5 and an invisible ink layer 6.

[0025] like Figure 1The UV primer layer 3 is partially brushed on the ink layer 2, and the UV varnish layer 4 is entirely brushed on the ink layer 2 and the UV primer layer 3. The contact portion of the UV primer layer 3 and the UV varnish layer 4 undergoes a cohesive reaction to form a fine granular ink film, constituting a matte or frosted surface, and a high-gloss mirror surface is formed in the portion without the UV primer, so that the overlapping portion of the UV primer layer 3 and the UV varnish layer 4 forms a matte area, and the non-overlapping portion of the UV primer layer 3 and the UV varnish layer 4 forms a highlight area, which also forms a local high-gloss area and a local frosted low-gloss area on the surface of the packaging box, achieving a high-contrast effect of local graphics and texts, highlighting the pattern of the gloss mirror in the highlight area, and having a special visual effect.

[0026] The matte area is provided with a first photochromic layer 5, which is distributed between the ink layer 2 and the UV primer layer 3. The first photochromic layer 5 has a photochromic pattern. The first photochromic layer 5 is printed with a photochromic material. When the photochromic material is irradiated with ultraviolet rays or light of a specific wavelength, its molecular structure will change, resulting in a color change, so that the first photochromic layer 5 and the photochromic pattern can change color under ultraviolet rays, and the color change reaction is reversible and can be gradually restored under natural light. The use of photochromic materials for anti-counterfeiting identification is widely used in the field of anti-counterfeiting printing, which will not be described here. In this embodiment, the first photochromic layer 5 is located in the matte area, and the low reflective characteristics of the matte area are used to enhance the intuitiveness and visibility of the color change, forming a special visual effect.

[0027] An invisible ink layer 6 is coated in the highlight area. The invisible ink layer 6 is partially arranged between the ink layer 2 and the UV varnish layer 4. An invisible pattern is provided on the invisible ink layer 6. The invisible ink layer 6 is printed with invisible fluorescent ink. The invisible varnish ink does not show up under natural light, but only shows a fluorescent effect under ultraviolet light, so that the invisible ink layer 6 and the invisible pattern are only visible under ultraviolet light. The use of invisible fluorescent ink for anti-counterfeiting identification is widely used in the field of anti-counterfeiting printing, which will not be elaborated here.

[0028] During actual printing, according to the pattern color plate, the first photochromic layer 5 and the invisible ink layer 6 are printed first, and then the UV primer layer 3 is printed on the first photochromic layer 5. The area of ​​the UV primer layer 3 needs to be able to cover the first photochromic layer 5, so that the first photochromic layer 5 is located in the matte area, and finally the entire layer is fully coated with the UV varnish layer 4.

[0029] During anti-counterfeiting identification, first, the difference in visual effects between the matte area and the highlight area brought about by the reverse glazing process itself can be used as an anti-counterfeiting standard; then, whether the photochromic pattern and the invisible pattern are smoothly displayed under ultraviolet light is used as the second anti-counterfeiting standard; finally, under ultraviolet light, the special visual effects of the first photochromic layer 5 in the matte area and the invisible ink layer 6 in the highlight area are used as the third anti-counterfeiting standard.

[0030] In order to further increase the anti-counterfeiting identification features, in this embodiment, the ink layer 2 and the basic pattern are completely covered on the paper base 1, the photochromic pattern and the invisible pattern are partially covered on the basic pattern, the photochromic pattern and the invisible pattern do not overlap, and there is no need to completely cover the basic pattern; the first photochromic layer 5 is a colored coating, the photochromic pattern is in a color state under natural light, and the photochromic pattern and the basic pattern are combined under natural light to form the overall appearance pattern of the packaging box. Under ultraviolet light, the photochromic pattern changes color, and the invisible pattern appears and covers a part of the basic pattern, so that the basic pattern, the photochromic pattern and the invisible pattern are combined to form an anti-counterfeiting pattern. The anti-counterfeiting pattern is different from the appearance pattern, and the shape characteristics of the anti-counterfeiting pattern serve as a new anti-counterfeiting standard.

[0031] In order to further increase the anti-counterfeiting identification features, the anti-counterfeiting pattern includes an anti-counterfeiting information QR code. In this embodiment, the anti-counterfeiting information QR code is formed by combining partial pattern features of the basic pattern, the photochromic pattern and the invisible pattern, so that the pattern composition of the anti-counterfeiting information QR code itself has an anti-counterfeiting function. The anti-counterfeiting information QR code includes verification information and can be identified by scanning the code.

[0032] In order to facilitate the printing of the first photochromic layer 5 and the invisible ink layer 6 and avoid affecting the ink layer 2 , a transparent protective layer 8 is provided on the ink layer 2 , and the first photochromic layer 5 and the invisible ink layer 6 are both provided on the transparent protective layer 8 .

[0033] In order to facilitate anti-counterfeiting identification, a second photochromic layer 7 is additionally provided in a specific area of ​​the highlight area. The second photochromic layer 7 is locally arranged between the ink layer 2 and the UV varnish layer 4. The second photochromic layer 7 and the invisible ink layer 6 are arranged alternately without overlapping. The material composition and construction process of the second photochromic layer 7 are consistent with those of the first photochromic layer 5. The only difference is that the first photochromic layer 5 is distributed in the matte area, while the second photochromic layer 7 is distributed in the highlight area.

[0034] Due to the different light transmission efficiency of the matte area and the highlight area, the color reaction speed of the first photochromic layer 5 and the second photochromic layer 7 will be different under ultraviolet irradiation. The rough surface of the matte area causes more ultraviolet scattering, and the first photochromic layer 5 changes color slowly, which is not as obvious as the second photochromic layer 7. Through the difference in color reaction speed, anti-counterfeiting identification can be effectively performed to form a complex and difficult-to-copy anti-counterfeiting feature. For example, the anti-counterfeiting pattern includes a winding vine, which runs through the highlight area and the matte area. The pattern in the highlight area is composed of the second photochromic layer 7, which mainly includes the vine body features, and the pattern in the matte area is composed of the first photochromic layer 5, which mainly includes hidden detail features; irradiated with ultraviolet light, observe the changes of the vine pattern in the highlight area and the matte area, the vine pattern in the highlight area changes color quickly, the colors of the leaves and flowers become bright, and the basic shape appears, while the vine pattern in the matte area gradually shows color, wherein the hidden detail pattern features gradually appear during the color change process, and anti-counterfeiting identification can be performed by observing the presence or absence of the detail pattern.
