[0025] The present invention provides a pull-open bottle cap with a curved QR code and a manufacturing method thereof, which has the following features:

[0026] Beneficial effects:

[0027] The easy-pull bottle cap with a curved QR code and the manufacturing method thereof can produce an easy-pull beer bottle cap with less deformation, thereby reducing the deformation curvature at the QR code position and facilitating the scanning and reading of the QR code.

[0028] 1. The easy-to-pull bottle cap with a curved QR code and its manufacturing method: During the preparation process, the outer ring area and inner ring area of ​​the bottle cap main body cap top and the anti-wear convex strips on the outer side wall, the outer fixing ring and the engaging cap teeth are integrally formed, and the stamping speed is relatively fast. The outer ring area with an arc-shaped arched structure makes the periphery of the bottle cap main body a convex structure, which increases the area compared with the flat structure, thereby reducing the influence of the deformation degree on the inner periphery of the bottle cap main body when opening the cap, so that the deformation area when opening the cap is covered to the outer part to the greatest extent, and the anti-wear convex strips are in the shape of a raised strip, which is convenient for protecting the outer wall of the bottle cap main body and increasing the friction force. The provision of the outer fixing ring can enhance the structural strength of the bottle cap main body.

[0029] 2. The easy-to-pull bottle cap with a curved QR code and its manufacturing method, through the process of component assembly, add a reinforcement ring, a gasket and a welded reinforcement plate inside the bottle cap. The inner wall of the reinforcement ring is provided with a gasket. The setting of the outer fixing ring can enhance the structural strength of the bottle cap body, and the setting of the gasket can play a sealing role to seal the beer bottle mouth. The setting of the reinforcement plate can bear the deformation pressure and avoid deformation of the area covered by the reinforcement plate.

[0030] 3. The easy-open bottle cap with a curved QR code and its manufacturing method have a semi-enclosed reinforcing sheet structure that can surround the QR code, so that when the cap is opened, the deformed area is located at the opening of the reinforcing sheet on the side away from the QR code, thereby reducing the deformation curvature of the QR code position. The design allows the QR code to be fully exposed after the bottle cap body is opened, and at the same time, the QR code can be placed at the position where the curvature of the bent and deformed bottle cap body is the smallest. These all make the QR code easy to scan. Therefore, this design greatly improves the readability of the QR code and significantly accelerates the reading speed.

[0031] 4. The easy-open bottle cap with a curved QR code and its manufacturing method have a pull ring structure of the easy-open component that facilitates opening the cap, and the convex cap portion can also bear a portion of the deformation pressure. Moreover, when the pressure inside the beer bottle is too high due to external factors, the inner side of the convex cap that fits with the bottle mouth has no engaging cap teeth and will be expanded, causing air leakage, thereby reducing the risk of the beer bottle exploding after packaging.

[0038] See also Figure 1 , the outer ring area 2 is an arc-shaped arched structure, and the symmetry center of the outer ring area 2 and the inner ring area 3 are concentric circle structures;

[0039] The outer ring area 2 with an arc-shaped arched structure makes the periphery of the bottle cap body 1 a convex structure, which increases the area compared to the flat structure, thereby reducing the impact of the deformation degree on the inner periphery of the bottle cap body 1 when opening the cap, so that the deformation area when opening the cap is covered to the outer part to the greatest extent.

[0040] Please refer to 2 , the protective component 4 includes an anti-wear rib 401 and an outer fixing ring 402 . The anti-wear rib 401 is fixed on the upper portion of the outer wall of the bottle cap body 1 , and the outer fixing ring 402 is fixed in the middle portion of the outer wall of the bottle cap body 1 .

[0041] The specific operation is as follows: the anti-wear rib 401 is a raised strip-shaped structure, which is convenient for protecting the outer wall of the bottle cap body 1 and increasing the friction force. The setting of the outer fixing ring 402 can enhance the structural strength of the bottle cap body 1.

[0042] See also Figure 3 The symmetry center of the reinforcement ring 601 coincides with the symmetry center of the bottle cap body 1, and the reinforcement ring 601 is an annular hollow structure; the reinforcement sheet 603 inside the reinforcement ring 601 is a semi-closed structure, and the reinforcement sheet 603 is fixedly connected to the bottle cap body 1;

[0043] There is a gasket 602 on the outer wall of the reinforcement ring 601. The setting of the outer reinforcement ring 402 can enhance the structural strength of the bottle cap body 1, and the setting of the gasket 602 can play a sealing role to seal the beer bottle mouth. The reinforcement sheet 603 can bear the deformation pressure to avoid deformation of the area covered by the reinforcement sheet 603. The reinforcement sheet 603 has a semi-closed structure that can surround the QR code 7, so that when the cover is opened, the deformation area is located at the opening of the reinforcement sheet 603 away from the QR code 7, thereby reducing the deformation curvature of the QR code 7 and facilitating the scanning and reading of the QR code 7.

[0044] See also Figure 1-4 The manufacturing method of the easy-open bottle cap with a curved QR code comprises the following steps:

[0045] S1. Raw material cutting

[0046] Aluminum alloy is used as the raw material for bottle cap processing. The surface of the aluminum alloy is flattened by a roller to make it smooth and uniform in thickness. Then, aluminum alloy sheets of corresponding sizes are cut out as bottle cap blanks.

[0047] S2. Stamping preparation

[0048] The aluminum alloy sheet blank is stamped and placed on the corresponding bottom die position of the bottle mouth during stamping, and the upper part is stamped with the corresponding stamping composite die;

[0049] S3. Component Assembly

[0050] A reinforcement ring 601 is integrally welded to the interior of the bottle cap body 1 , and a reinforcement sheet 603 is welded to the inner side of the reinforcement ring 601 . Then, a gasket 602 is pressed and fixed to the inner side of the reinforcement ring 601 by a compression molding process without adding any glue.

[0051] S4, pull ring fixation

[0052] The outer convex cover 801 of the bottle cap body 1 is fixed with a fixing buckle 802 and a pull ring 803 by injection molding. The pull ring 803 is made of plastic. The pull ring 803 is then trimmed to prevent the outer edge of the pull ring 803 from causing injury to the user.

[0053] S5, QR code spraying

[0054] The easy-open bottle cap can be manufactured by spraying or engraving the two-dimensional code 7 on the inner side of the bottle cap body 1 using an inkjet printer or a laser coding machine.

[0055] During the stamping preparation process of S2, the dimensions of the bottom die of the bottle mouth used for stamping and the upper stamping composite die are consistent.

[0056] During the stamping process of S2 , the outer ring area 2 and the inner ring area 3 of the top of the bottle cap body 1 , the anti-wear convex strips 401 of the outer wall, the outer fixing ring 402 and the engaging cap teeth 5 are integrally formed.

[0057] The size of QR code 7 is 6*6mm, and the error range of QR code 7 is 0.5mm; the level of QR code 7 is 3, and it can accommodate 47 characters when the error correction level is Q, which can meet the current usage requirements. When the number of characters is required to be 35 or less, the error correction level will be upgraded to H, which will further improve the readability. This size requirement and structural setting greatly improve the readability of QR code 7.

[0058] In summary, the easy-to-pull bottle cap with a curved QR code and its manufacturing method, when used, first need to complete the processing and preparation of the bottle cap body 1, during the preparation, take aluminum alloy as the bottle cap processing raw material, use a pressure roller to flatten the aluminum alloy surface to make its surface flat and uniform in thickness, and then cut out aluminum alloy sheets of corresponding sizes as bottle cap blanks; then stamp the aluminum alloy sheet blank, and put it on the corresponding bottle mouth bottom mold position during stamping, and use the corresponding stamping composite mold to stamp the upper part, so that a plurality of anti-wear convex strips 401 are formed on the upper part of the outer part, an outer fixing ring 402 protrudes in the middle, and a plurality of bite cover teeth 5 are formed on the lower part of the outer part, completing the preliminary preparation; then the reinforcing ring 6 is welded integrally inside the bottle cap body 1 01, at the same time, the reinforcing sheet 603 is continued to be welded on the inner side of the reinforcing ring 601, and the reinforcing ring 601 is integratedly welded inside the bottle cap body 1. At the same time, the reinforcing sheet 603 is continued to be welded on the inner side of the reinforcing ring 601, and then the gasket 602 is pressed and fixed on the inner side of the reinforcing ring 601 by the compression molding process without adding any glue; the fixing buckle 802 and the pull ring 803 are fixed on the outer convex cover 801 area of ​​the outer cap body 1 by injection molding. The pull ring 803 is made of plastic, and then the pull ring 803 is trimmed to avoid sharp corners on the outer edge of the pull ring 803 to cut the user; finally, a printer or laser coder is used to spray or engrave the QR code 7 on the inner side of the bottle cap body 1 to complete the processing and manufacturing of the easy-open bottle cap;

[0059] When in use, the anti-wear rib 401 is in the shape of a raised strip, which is convenient for protecting the outer wall of the bottle cap body 1 and increasing the friction force. The setting of the outer fixed ring 402 can enhance the structural strength of the bottle cap body 1, and the setting of the gasket 602 can play a sealing role to seal the beer bottle mouth. When the cap needs to be opened, it can be opened through the pull ring 803 structure of the easy-to-open assembly 8. The outer convex cover 801 part can also bear part of the deformation pressure. When the pressure in the beer bottle is too high due to external factors, the inner side of the outer convex cover 801 that fits the bottle mouth has no engaging cover teeth 5 and will be expanded, causing air leakage, thereby reducing the risk of the beer bottle exploding after packaging.

[0060] The outer ring area 2 with an arc-shaped arched structure during the opening process can reduce the influence of the deformation degree on the inner periphery of the bottle cap body 1 when the cap is opened, so that the deformation area of ​​the opening is covered on the outer part to the greatest extent, and the reinforcing sheet 603 can bear the deformation pressure to avoid deformation of the area covered by the reinforcing sheet 603. The reinforcing sheet 603 has a semi-closed structure and can surround the QR code 7, so that the deformation area is located at the opening of the reinforcing sheet 603 away from the QR code 7 when the cap is opened, thereby reducing the deformation curvature of the QR code 7 and facilitating the scanning and reading of the QR code 7. This design can make the QR code 7 completely exposed after the bottle cap body 1 is opened, and at the same time can place the QR code 7 at the position with the smallest curvature of the bent and deformed bottle cap body 1. All of these make the QR code 7 easy to scan. Therefore, this design greatly improves the readability rate of the QR code 7 and significantly speeds up the reading speed, thus completing the entire use process of the easy-to-pull bottle cap with a curved QR code and its manufacturing method.
