Problems solved by technology

[0004] However, in the existing process, when setting identification codes such as two-dimensional codes on the surface of the crown, it is necessary to use spraying, laser burning or etching methods to form an identification code with a concave-convex structure on the surface of the crown. The surface is not smooth, which affects the appearance
In addition, there will be a lot of smoke and dust during the production process, and the need to use a relatively high-power laser will consume a lot of energy and have a great impact on the environment

[0035] combine figure 1 and figure 2 It can be seen that, in this embodiment, the structure of the crown cover includes a circular top 11 and a skirt 12 integrally formed with the top 11, which is formed in a photon-sensitive ink layer arranged on the inner side of the top 11 (that is, the back of the crown) There is a first grayscale identification code 14, and a sealing injection molding gasket 13 made of silicone material is also arranged on the inner side of the top 11. The upper surface of the sealing injection molding gasket 13 is pasted on the surface of the photon-sensitive ink layer arranged on the inner side of the top 11 through an adhesive layer .

[0036] Specifically, as Figure 3a and Figure 3b As shown, the top 11 and the skirt 12 respectively include a substrate 100 and photon-sensitive ink layers 101 disposed on both sides of the substrate 100 . Wherein, the photon-sensitive ink layer disposed on the inner side of the substrate 100 is exposed and forms ...

[0042] Such as Figure 5 and Figure 6 As shown, the structure of the second embodiment is basically the same as that of the first embodiment, the difference is that: not only the first grayscale identification code 24 is formed on the inner side of the top 21 (that is, the back side of the crown cover), but also on the outer side of the top 21 (ie the front of the crown cover) forms the second grayscale identification code 25 .

[0043] Specifically, as Figure 7a and Figure 7b As shown, the top 21 and the skirt 22 respectively include a substrate 200 and photon-sensitive ink layers 201 disposed on both sides of the substrate 200 . Wherein, the photon-sensitive ink layer arranged on the inner side of the substrate 200 is exposed and forms the first grayscale identification code 24 (such as Figure 7a shown) or the photon-sensitive ink layer disposed on the inner side of the substrate 200 is covered by the inner coating 203 after the first grayscale identification code 24...

[0049] Such as Figure 10 to Figure 12 As shown, the structure of the third embodiment is basically the same as that of the crown caps provided by the first embodiment and the second embodiment, the difference is that a first gray scale mark is provided on the inner side of the crown cap skirt 32 Code 36. Since the top 31 and the skirt 32 of the crown are integrally formed, the skirt 32 of the crown has the same structure as the top 31, which includes a substrate and photon-sensitive ink layers arranged on both sides of the substrate, wherein the substrate is arranged on the substrate The photon-sensitive ink layer on the inner side is exposed and forms the first grayscale identification code 36 (such as Figure 11 shown). Due to the limited size of the skirt, the first gray-scale identification code 36 set on the inner side of the skirt 32 is recommended to use a short character code composed of letters and numbers, and a combination of words and letters or numbers can also...

Abstract

The invention discloses a metal crown lid with a gray level identification code. The metal crown lid with the gray level identification code comprises a circular top and a skirt. At least one gray level identification code is arranged at the top and / or the skirt, the top and the skirt comprise base materials and photon sensitive ink layers arranged on the inner sides and / or outer sides of the base materials correspondingly, the gray level identification code is an image which is formed after a part of photon active materials in each photon sensitive ink layer is changed in appearance, the surface of the gray level identification code is smooth, a gray level difference exists in the surface of the gray level identification code and the surrounding area. According to the metal crown lid, the at least one gray level identification code which is manufactured by photon sensitive ink is arranged at the top and / or the skirt, because only the appearances of the photon active ingredients in the photon sensitive ink layers are changed, the photon sensitive ink cannot be burned, etched or fall off, so changing of a product appearance cannot be brought in and therefore the metal crown lid has a smooth and attractive appearance.

Description

technical field [0001] The invention relates to a crown cap, in particular to a crown cap with an identification code. Background technique [0002] The popularization and application of the Internet of Things is inseparable from the automatic identification of identification codes (including but not limited to QR codes or digital codes, etc.). The identification code represented by the two-dimensional code has the characteristics of large data storage capacity and good confidentiality, and can be better combined with mobile terminals such as smart phones to form a good interaction and user experience. Therefore, the two-dimensional code is in widely used in today's society. In recent years, people have successively proposed a variety of schemes to use QR codes for product anti-counterfeiting, point marketing, product traceability, and anti-smuggling. [0003] For example, the applicant discloses an anti-counterfeit bottle cap in the Chinese utility model patent No. ZL2014...
