Technical Field

[0001] The utility model relates to a bottle cap connecting inner sleeve, in particular to an anti-stripping double-material injection-molded liquor anti-counterfeiting bottle cap connecting inner sleeve. Background Art

[0002] The inner sleeve is a part of the liquor anti-counterfeiting bottle cap structure that comes into contact with the liquor body. Its main function is to connect the bottle mouth and other various parts of the bottle cap. Currently on the market, the inner sleeve is generally formed by one-piece injection molding of food-grade plastic particles such as PET, PC or PP, and there are also AS injection molding parts and ABS welding methods. The inner sleeve is equipped with an inverted latch. After being pressed with the wine bottle, the latch latches the bottle cap to prevent the bottle cap from separating from the bottle body, thus playing an anti-counterfeiting role.

[0003] The existing technical defects mainly include the following points:

[0004] 1. The bottle cap is easy to be physically removed after being put on the bottle, which reduces the anti-counterfeiting property of the bottle cap.

[0005] 2. It is not resistant to high temperatures. The bottle cap can be easily removed from the bottle by boiling or heating, which will also reduce the anti-counterfeiting property.

[0006] 3. If ultra-high strength and ultra-high temperature resistant materials are used for production, the materials cannot meet the food hygiene requirements, thus limiting the widespread use of the materials. Utility Model Content

[0007] In view of the deficiencies in the existing technology, the utility model aims to provide an anti-slip double-material injection-molded white wine anti-counterfeiting bottle cap connecting inner sleeve.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a non-peeling double-material injection-molded white wine anti-counterfeiting bottle cap connecting inner sleeve, the connecting inner sleeve is an integrally formed structure formed by two-color / double-material injection molding, including a bottle mouth part made of food-grade plastic and a bottle neck part made of high-temperature resistant and high-strength plastic, and a liquid outlet is provided on the top of the bottle mouth part.

[0009] Further, the bottle mouth is a cover-shaped structure, and the bottom of the bottle mouth is annular, the bottom of the bottle mouth is provided with a step, the step is provided with at least one group of first buckles, and each group of first buckles is symmetrically arranged through the axis of the bottle mouth; correspondingly, the bottle neck is an annular structure, the top of the bottle neck is provided with at least one group of first buckles matched with the first buckles, and each group of first buckles is symmetrically arranged through the axis of the bottle neck of the annular structure;

Correspondingly, the bottleneck portion is an annular structure, and the top of the bottleneck portion is provided with at least one group of second slots that cooperate with the second buckles, and each group of second slots is symmetrically arranged through the axis of the bottleneck portion of the annular structure.

[0011] Furthermore, the first buckle includes three block-shaped protrusions arranged at intervals, and correspondingly, the first slot includes three notches that can accommodate the block-shaped protrusions.

[0012] Furthermore, the second card slot includes a first bottom groove, a second bottom groove and a "concave" protrusion located therebetween, and a plug is provided on the side of the "concave" protrusion facing the inner side of the bottleneck, and correspondingly, a socket that cooperates with the plug is provided at the connection between the second buckle and the step, and the second buckle includes a first top protrusion, a second top protrusion and a "convex" protrusion located therebetween.

[0013] Furthermore, at least one group of through holes is provided on the peripheral side surface of the bottleneck portion, and each group of through holes is symmetrically arranged about the axis of the bottleneck portion.

[0016] Furthermore, the bottleneck portion is provided with anti-slip grooves around its inner wall at intervals.

[0017] The beneficial effects of the utility model are as follows: the utility model adopts a bottleneck made of high-temperature resistant and high-strength plastic to enhance the strength of the inverted latch teeth combined with the bottle mouth, thereby ensuring that the connecting inner sleeve firmly buckles the bottle lip, greatly improving the strength of the bottle cap connecting the inner sleeve, thereby solving the problem that the bottle cap is easily pulled off the bottle under physical force or at high temperature, and improving the anti-counterfeiting function of the bottle cap product.

[0018] The bottle mouth can be separated from the bottle neck under great physical force and cannot be restored and is easy to identify, which further improves the anti-counterfeiting function.

[0019] The inner sleeve of the bottle cap remains a complete accessory through two-color / two-material injection molding and does not require assembly.

[0025] like Figure 1-Figure 4 As shown, an anti-peeling double-material injection-molded white wine anti-counterfeiting bottle cap connecting inner sleeve, the connecting inner sleeve is an integrally formed structure formed by two-color / double-material injection molding, including a bottle mouth part 1 made of food-grade plastic and a bottleneck part 2 made of high-temperature resistant and high-strength plastic, and a liquid outlet is provided on the top of the bottle mouth part 1.

[0026] In the above structure, through the design of the two-color mold structure, the connecting inner sleeve is divided into two parts, the bottle mouth part 1 and the bottle neck part 2, and two different raw materials are used for injection molding respectively. According to the food-grade hygiene standard of the liquor bottle cap and the requirements of the anti-counterfeiting functional requirements of boiling resistance and anti-pull-off, the bottle mouth part 1 adopts raw materials of food-grade hygiene standards, such as PET, PC, PP, etc.; the bottle neck part 2 adopts high temperature and boiling resistance plastics, such as nylon + glass fiber, etc. (not limited to the above types). Through the design of the mold structure, the joints of the two materials are staggered and integrated. This technology is conducive to the rapid injection molding of the product on the injection molding machine, and the connecting inner sleeve is still a whole; reducing the assembly links in the post-process is conducive to improving production efficiency.

[0027] At the same time, dual anti-counterfeiting functions are achieved. First, the bottleneck portion 2 is formed by a material that is resistant to boiling and high temperature, and has a stronger anti-deformation force, so it maintains cooperation with the bottle mouth and will not be easily pulled off, thereby achieving the anti-pulling and anti-counterfeiting function requirements; second, the structural design of the joint surfaces and points of two different raw materials through the mold not only ensures that the torque, deformation force, and pulling force performance requirements of the normal production and assembly of the anti-counterfeiting bottle cap are met, but also has the function of separating the bottle mouth portion 1 from the pulling surface / point and the bottleneck portion 2 through a strong pulling force; thereby achieving the anti-counterfeiting function of the inner sleeve and the bottle mouth portion 1 being detached and unable to be restored and easy to identify.

[0028] The bottle mouth 1 is a cover-shaped structure, and the bottom of the bottle mouth 1 is annular. A step 3 is provided at the bottom of the bottle mouth 1, and at least one group of first buckles 31 is provided on the step 3. Each group of first buckles 31 is symmetrically arranged through the axis of the bottle mouth 1. Correspondingly, the bottle neck 2 is an annular structure, and at least one group of first slots 21 cooperating with the first buckles 31 is provided on the top of the bottle neck 2. Each group of first slots 21 is symmetrically arranged through the axis of the bottle neck 2 of the annular structure.

[0029] At least one group of second buckles 32 are also provided on the step 3, and each group of second buckles 32 are symmetrically arranged through the axis of the bottle mouth 1. Correspondingly, the bottleneck 2 is an annular structure, and the top of the bottleneck 2 is provided with at least one group of second slots 22 that cooperate with the second buckles 32, and each group of second slots 22 are symmetrically arranged through the axis of the bottleneck 2 of the annular structure.

[0030] The first buckle 31 includes three block-shaped protrusions 311 that are spaced apart from each other. Correspondingly, the first slot 21 includes three notches 211 that can accommodate the block-shaped protrusions 311 .

[0031] The second card slot 22 includes a first bottom groove 221, a second bottom groove 222 and a "concave" protrusion 223 located therebetween. The "concave" protrusion 223 is provided with a plug 23 on the side facing the inner side of the bottleneck portion 2. Correspondingly, a socket 33 cooperating with the plug 23 is provided at the connection between the second clip 32 and the step 3. The second clip 32 includes a first top protrusion 321, a second top protrusion 322 and a "convex" protrusion 323 located therebetween.

[0032] At least one group of through holes 4 is provided on the peripheral side of the bottleneck portion 2 , and each group of through holes 4 is symmetrically arranged about the axis of the bottleneck portion 2 .

[0033] The through hole 4 is provided with two undercut teeth 5 inclined toward the inner side of the bottleneck 2 .

[0034] The peripheral side surface of the bottle mouth portion 1 is provided with a spiral protrusion 6 .

[0035] The bottleneck portion 2 is provided with anti-slip grooves 7 around the inner wall thereof at intervals.

[0036] Beneficial effect: By adopting the bottleneck part 2 made of high-temperature resistant and high-strength plastic, the strength of the inverted latch teeth 5 combined with the bottle mouth is enhanced, thereby ensuring that the connecting inner sleeve firmly buckles the bottle lip, greatly improving the strength of the bottle cap connecting the inner sleeve, thereby solving the problem that the bottle cap is easily pulled off the bottle under physical force or at high temperature, and improving the anti-counterfeiting function of the bottle cap product.

[0037] The bottle mouth portion 1 can be separated from the bottle neck portion 2 under a large physical force and cannot be restored and is easy to identify, thereby further improving the anti-counterfeiting function.

[0038] The bottle cap and the inner sleeve are still a complete accessory through two-color / two-material injection molding, and no assembly is required.

[0039] Compared with other split or inlaid steel ring anti-counterfeiting inner sleeves, it reduces production costs, reduces production processes and improves production efficiency.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, simple changes and substitutions by ordinary technicians in this field are within the protection scope of the utility model.
