detailed description

Below in conjunction with accompanying drawing and specific embodiment, the technical content of the utility model is described further.

first embodiment

As shown in FIG. 1 and FIG. 2 , the fully open easy-open lid provided by the utility model includes a lid frame 1 , a safety edge 2 and a closure piece 3 . Among them, the cover frame 1, the safety edge 2 and the closure piece 3 can be integrally formed by stamping with a metal mold, and a score line 6 is provided between the closure piece 3 and the safety edge 2, and the closure piece is realized by tearing the score line 6. 3 and the separation of the safe side 2. The wide end of the pull ring 4 is provided with a pull hole 5 , the narrow end of the pull ring 4 is a solid area, and its narrow front end forms a pointed portion. The narrower end of the pull ring 4 is riveted to the area near the edge of the closure piece 3 by a rivet 8 , and the tip of the front end of the pull ring 4 is aligned with the score line 6 for destroying the score line 6 . In addition, a short corrugated scoring line 9 is provided around the riveted area of the pull ring 4 and the closure piece 3 on the full-open easy-open lid.

By lifting the pull ring 4, the score line 9 can be torn off, and the tip of the front end of the pull ring 4 is driven to destroy the score line 6; The closure piece 3 is separated from the safety edge 2, and the easy-to-open lid is opened. The full-open easy-open lid may not be provided with a safety edge, but it is preferably provided with a safety edge to ensure that after the closure piece is opened, the edge of the cover frame is smoother and does not hurt hands.

As shown in Figures 1 and 2, the above-mentioned full-open easy-open lid is provided with gray-scale identification codes on the front and back sides of the sealing sheet 3, wherein, on the inner side of the sealing sheet 3 (i.e. the back side shown in Figure 2) A first grayscale identification code 11 is provided, and one or more second grayscale identification codes 12 are provided on the outer side of the sealing sheet 3 (ie, the front side shown in FIG. 1 ). The sealing piece 3 has a relatively large area, which is large enough to set a plurality of grayscale identification codes whose area is approximately between 4*4mm ² and 10*10mm ² . Preferably, the first gray scale identification code 11 is set at any position where the back of the closure sheet 3 is not covered by the score line 6 and the score line 9, especially the center position of the closure sheet 3 is optimal; one or more second The grayscale identification code 12 can be arranged at any position where the front of the closure sheet 3 is not covered by the pull ring 4. When only the unique grayscale identification code is set on the front of the closure sheet 3, especially at the center of the front of the closure sheet 3 is optimal. In this full-open easy-open lid, by setting the first grayscale identification code 11 at the center of the closure piece 3, and setting the riveting point of the pull ring 4 near the edge of the closure piece 3, it is possible to avoid the The first grayscale identification code 11 arranged on the back of the sealing sheet 3 is destroyed during the process of setting the pull ring 3 on the top.

In the full-open easy-open lid, the sealing piece 3 has a structure as shown in Fig. 3a or Fig. 3b (refer to the partial cross-sectional enlarged view of A-A area shown in Fig. 1 ). The sealing sheet 3 at least includes a substrate 100 and photon-sensitive ink layers 101 disposed on both sides of the substrate 100 . Wherein, the photon-sensitive ink layer arranged inside the substrate 100 is exposed and forms the first grayscale identification code 11 (as shown in FIG. 3 a ) or the photon-sensitive ink layer arranged inside the substrate 100 is formed after the first grayscale identification code 11 Covered by the inner coating 103 (as shown in FIG. 3 b ), the first gray scale identification code 11 is arranged on the back of the sealing sheet 3 , preferably in an area close to the middle of the sealing sheet 3 or at the center of the sealing sheet 3 . The photon-sensitive ink layer arranged on the outside of the substrate 100 forms one or more second grayscale identification codes 12 , and the second grayscale identification codes 12 are arranged on an area outside the sealing sheet 3 that is not blocked by the pull ring 4 . The photon-sensitive ink layer disposed on the outside of the substrate 100 may be exposed, or may be covered by other transparent materials, such as varnish.

The photon-sensitive ink layer 101 arranged on both sides of the substrate 100 is formed by coating the photon-sensitive ink containing photon-active materials on the surface of the substrate 100. According to product requirements, the photon-sensitive ink layer 101 can cover the substrate in whole or in part. The surface of the material 100. Since the photon-sensitive ink layer 101 contains photon-active materials that are more sensitive to laser light, when the laser light hits the photon-sensitive ink layer 101 including photon-active components, the photon-active components therein will change in a visually perceptible manner, resulting in The photon-sensitive ink undergoes a change in appearance. Preferably, the change in appearance is a change in colour, eg from a transparent or light colour, to an opaque or darker colour. In other words, the grayscale identification code cited in this application refers to an image formed by grayscale changes in a broad sense, and does not limit the color of the formed identification code to be gray. In practice, other colors can be formed, such as black.

In the present invention, the appearance of the photon active components can be changed by using a laser with low power, so that the appearance of part of the photon active material 102 in the photon-sensitive ink layer changes, forming a smooth surface but grayscale difference with the surrounding area images with virtually no burning, etching, or peeling of photon-sensitive inks. For example, use CO ₂ infrared laser or near-infrared laser irradiation with power less than 10W to produce monochromatic or colored laser images. The aforementioned images broadly contain decorations (such as logos, pictures or aesthetic marks) or information (such as text or two-dimensional codes). For example, a decorative image or a trademark image can be formed on the front of the sealing sheet by changing the appearance of part of the photon-active material in the photon-sensitive ink layer. The surface of the decorative image or trademark image is smooth and has a grayscale difference from the surrounding area. Compared with the existing process of using laser ablation or spraying to make identification codes, after using photon-sensitive ink, a laser machine with a small power can be used to engrave better patterns, greatly reducing costs, greatly increasing engraving speed, and meeting online production High-speed requirements, but also play a good role in environmental protection.

Through the above-mentioned process, photon-sensitive ink layers are respectively coated on both sides of the substrate to form grayscale identification codes. When the photon-sensitive ink layer 101 uses photon-sensitive ink with safe edible properties, the photon-sensitive ink layer 101 can be directly in contact with the liquid in the tank, and the photon-sensitive ink layer 101 arranged on both sides of the substrate 100 can be directly exposed. Considering the long-term direct contact between the liquid in the tank and the photon-sensitive ink layer during storage and transportation, a small amount of reaction may occur, the surface of the photon-sensitive ink layer 101 arranged on the inside of the substrate 100 can also be coated with an existing inner coating 103.

The first grayscale identification code 11 arranged on the inner side of the sealing sheet 3 can be a two-dimensional code shown in Figure 2, or a character code, or any other unexampled number, letter, or text. Recognizable images of various compositions. Setting the first grayscale identification code 11 inside the sealing sheet 3 can ensure that the first grayscale identification code 11 will not be damaged during transportation and sales, and ensure the integrity of the first grayscale identification code 11 . Moreover, the first grayscale identification code 6 arranged on the inner side of the closure sheet 3 cannot be obtained until the closure sheet 3 is torn apart or destroyed along the score line 10. Therefore, only consumers who purchase the product can obtain the first grayscale. Identification code 11. The first grayscale identification code 11 can be used in marketing activities, and can also be used as an identification code for anti-counterfeiting and traceability. The information in the first grayscale identification code 11 set at the center position on the back of each sealing sheet 3 is different, and makes it uniquely correspond to a fully open easy-open cover, thereby constituting the product's identity identification code, realizing one thing one code.

Equally, the second grayscale identification code 12 that is arranged on the outside of the sealing sheet can be the two-dimension code shown in Figure 1, also can be other unillustrated character codes, can also be other not exemplified by numbers, letters, words An identifiable image composed of any one or more of . The information in the second gray-scale identification code 12 provided on the outside of each closure sheet 3 is different, and uniquely corresponds to a fully-opened easy-open cover, thereby constituting the product identification code. The second grayscale identification code 12 is in a position not blocked by the pull ring 4 on the outside of the sealing sheet, and it is in an identifiable state during product transportation and sales, so it can be used for purposes such as anti-channeling or anti-counterfeiting traceability, which is convenient for consumers or consumers. The salesperson acquires. In addition, it is also possible to perform identity authentication by scanning the second grayscale identification code 7, and input the character code on the inside of the fully open easy-open cover or scan the QR code to conduct anti-counterfeiting authentication or participate in marketing activities.

In this embodiment, the first grayscale identification code 11 and the second grayscale identification code 12 are shown in two-dimensional codes. In order to ensure the clarity of the identification code pattern, the first grayscale identification code 11 and the second grayscale identification code The setting area of the grayscale identification code 12 is preferably not less than 1cm ² . Moreover, the information in the first grayscale identification code 11 and the information in the second grayscale identification code 12 set on the same full-open easy-open cover are different from each other and are correlated in the database. By setting double identification codes on the sealing piece 3, it can not only meet the normal information query requirements in the production and sales process, but also prevent the identification codes participating in the activities from being damaged or counterfeited in the sales process, and can ensure that both manufacturers and consumers legal rights.

second embodiment

The structure of the full-open easy-open lid shown in the second embodiment is basically the same as that of the first embodiment, and the difference is that in the two embodiments, the shielding area of the pull ring 4 on the closure piece 3 occupies 30% of the area of the closure piece 3. The proportion of the total area is different; the second grayscale identification code and the pull ring 4 have different relative positional relationships on the closure sheet 3; and the first grayscale identification code in the two embodiments uses two different identification codes , the second grayscale identification code in the two embodiments uses two different types of two-dimensional codes.

Specifically, in the first embodiment shown in Fig. 1 and Fig. 2, the volume of the pull ring 4 is small, and the ratio of the pull ring 4 to the total area of the closure piece 3 is less than 1/4, and the center position of the closure piece 3 is arranged The second grayscale identification code 11 is located outside the pull ring 4; and in the second embodiment shown in Fig. 4 and Fig. 5, the pull ring 4 has a larger volume, and the ratio of the pull ring 4 to the total area of the sealing sheet 3 is far more than 1/4, the second grayscale identification code 13 set at the center of the closure piece 3 is located on the closure piece 3 corresponding to the hollow area of the pull ring 4 (that is, located in the pull hole 5 of the pull ring 4).

In the first embodiment, the two grayscale identification codes 11 and 12 arranged on both sides of the sealing sheet 3 all use QM codes; in the fifth embodiment, the first grayscale identification code arranged on the back side of the sealing sheet 3 13 has used the DM code, and the second grayscale identification code 14 that is arranged on the front of the sealing sheet 3 has used a character code composed of numbers and letters. Under the same clarity, the DM code has a smaller setting area than the QR code.

It should be noted that although in the above two embodiments, the first grayscale identification code uses two different two-dimensional codes, and the second grayscale identification code uses two different identification codes, but the two fully open There is no essential difference in the use of the easy-open end. The two types of full-open easy-open end can meet the needs of anti-counterfeiting, anti-channeling and traceability management. The two-dimensional codes used in the above embodiments are easy to be recognized by machines, and the information carried by them can be obtained by scanning the grayscale identification codes with mobile terminal devices; while the character codes are generally short in length, easy to read, and also convenient for consumers to obtain.

In the above-mentioned embodiments, it has been described that one gray-scale identification code is provided on the inner and outer surfaces of the sealing sheet respectively. But its specific content does not constitute the limitation of the present utility model. For example, in the above-mentioned full-open easy-open lid, only the grayscale identification code can be set on the front or back of the closure sheet, or, according to the needs of merchants and consumers, multiple markings can be set on the front and/or back of the closure sheet. a grayscale code. In addition, according to the product design, other patterns formed by fluorescent ink can be set on the front of the easy-open cover, or transparent varnish can be applied.

To sum up, the full-open easy-open lid with gray-scale identification code provided by the utility model is provided with a gray-scale identification code made of photon-sensitive ink on one side or both sides of the sealing sheet. In the process of making gray-scale identification codes, since only the appearance of the photon-active components in the photon-sensitive ink is changed, the photon-sensitive ink will not be burned, etched or peeled off, so it will not bring about changes in the appearance of the product, thus making the photon-sensitive ink The full-opening easy-open lid has a smooth and beautiful appearance. Moreover, compared with the existing process of using laser ablation or spraying to make identification codes, after using photon-sensitive ink, a laser machine with a small power can be used to engrave better patterns, which greatly reduces costs and greatly increases engraving speed. The high-speed requirements of online production also play a good role in environmental protection. The full-open easy-open lid realizes one code for one item by setting gray-scale identification codes containing different information on the closure sheets of different products, which can protect the rights of consumers and manufacturers at the same time, and is convenient for use in marketing activities.
