Abstract
Description
Technical Field
[0001] This invention relates to the field of anti-counterfeiting packaging technology, and in particular to an anti-counterfeiting structure for a hat body that prevents secondary alteration. Background Technology
[0002] Currently, in the fields of liquor, high-end food, and pharmaceuticals and health products, heat-shrinkable caps are commonly used to seal the bottle openings. These caps typically have heat-shrink properties, and through heat treatment, they are made to fit tightly to the bottle cap and neck. This not only serves to fix and seal the bottle but also prevents loosening and leakage during transportation. To facilitate opening for consumers, existing caps often have tear strips or opening strips. Users can pull on these strips to tear the cap in a predetermined direction, thereby exposing the bottle cap underneath for opening.
[0003] In practical applications, the anti-counterfeiting features of existing anti-counterfeiting caps are not strongly correlated with the structure of the cap itself, and the destruction mechanism is relatively simple. It is difficult to effectively prevent the caps from being recycled in whole or in part for reuse. According to market research and media reports, the relevant counterfeiting industry chain has developed relatively mature counterfeiting techniques. Related practitioners collect caps and other accessories from genuine wine packaging at high prices, then fill them with non-original bottled wine and reseal them. In this process, since the anti-counterfeiting marks on existing caps are mostly only attached to the surface and the opening method is mostly simple physical tearing, counterfeiters can use sophisticated heat repair methods (such as using a heat gun to reseal) to illegally transfer these anti-counterfeiting components, which should be used only once, to counterfeit products.
[0004] Therefore, in the context of counterfeiting high-value-added alcoholic beverages through recycling, there is a problem of the capsules being reused. Summary of the Invention
[0005] The technical solution of the present invention is as follows: a hat body anti-counterfeiting structure to prevent secondary alteration, which is set on the main body of a rubber hat, including a main body, a tear film and a tear head. A self-adhesive area is provided on the outer wall of the main body. The tear film and the tear head are bonded to the self-adhesive area of the main body by adhesive. One end of the tear head is a free end, forming a gripping part for holding. The other end of the tear head is bonded and fixed to the tear film and the main body. The surface of the tear head is coated, printed or hot-stamped with a first anti-counterfeiting material. A second anti-counterfeiting feature is loaded on the tear film by printing or photolithography. An anti-counterfeiting pattern is printed or hot-stamped on the surface of the main body. The anti-counterfeiting pattern penetrates the bonding area between the tear head and the main body.
[0006] Preferably, when using this anti-counterfeiting structure for the cap body, the opening function and anti-counterfeiting function of the cap are integrated into the same device. When the consumer pinches the tear head and rotates to open the cap, the tear head, the tear film and the main body of the cap will inevitably separate. This process destroys the anti-counterfeiting features loaded on the surface of the tear head and inside the tear film, thus solving the problem of the cap being reused.
[0007] Preferably, the tear-off film has a double-layer structure, consisting of a support layer and a graphic information layer from the inside out, with the graphic information layer constituting the second anti-counterfeiting feature.
[0008] Preferably, the tear head is made of one of the following materials: aluminum foil, plastic, or aluminum-plastic composite.
[0009] Preferably, the tear-off head has a multi-layer composite structure.
[0010] Preferably, the main body of the cap is made of a material selected from polyethylene terephthalate, polypropylene, polyvinyl chloride, polyethylene, polycarbonate, heat-shrinkable polyethylene terephthalate, heat-shrinkable polyvinyl chloride, or polyolefin plastic optical materials.
[0011] Preferably, the self-adhesive area is located at the rolled seam of the main body of the hat, with an adhesive width of 2.5mm to 5.0mm.
[0012] Preferably, the tear-off film is applied to the outer or inner surface of the main body of the cap.
[0013] Preferably, the adhesive strength between the tear film and the main body of the cap is greater than the bonding strength between the inner layers of the tear film, so as to ensure that the inside of the tear film is damaged when it is torn.
[0014] Preferably, the adhesive strength between the tear head and the tear film is equal to the adhesive strength between the tear film and the main body of the cap.
[0015] Preferably, the gripping part of the tearing head is exposed on the surface of the main body of the hat.
[0016] The beneficial effects of this invention are: 1. This invention integrates the opening function and anti-counterfeiting function of the cap into the same device. When the consumer pinches the tear head and rotates to open the cap, the tear head, the tear film and the main body of the cap will inevitably separate. This process destroys the anti-counterfeiting features loaded on the surface of the tear head and inside the tear film, thus solving the problem of the cap being reused.
[0017] 2. This invention incorporates multiple anti-counterfeiting features: a first anti-counterfeiting material on the surface of the tear-off head, a second anti-counterfeiting feature inside the tear-off film, and an anti-counterfeiting pattern on the surface of the main body of the cap. During the opening process, part of the anti-counterfeiting pattern remains on the main body of the cap, while part is peeled off with the tear-off head, forming an incomplete pattern. The information layer inside the tear-off film is damaged, and the anti-counterfeiting material on the surface of the tear-off head is also damaged due to peeling. This multiple destructive mechanism makes it almost impossible to restore or reuse the cap once it is opened.
[0018] 3. By rationally designing the bonding strength relationship between each component: the bonding strength between the tear head and the tear film is equal to the bonding strength between the tear film and the main body of the cap, and greater than the interlayer bonding strength inside the tear film. This ensures that when the cap is opened, interlayer damage will inevitably occur inside the tear film, rather than being completely peeled off from the bonding interface, thus ensuring that the anti-counterfeiting features are effectively destroyed.
[0019] 4. This invention is achieved using multi-layer composite materials and bonding processes. Each component can be prepared using conventional printing, coating, and composite processes, making production costs controllable and suitable for large-scale promotion and application.
[0020] 5. This invention is not only applicable to wine packaging, but can also be widely used in food, pharmaceutical, daily chemical and other fields that require anti-counterfeiting packaging, and has good versatility and market prospects. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Example 1: In this embodiment, the problem of reusing the rubber cap is addressed.
[0025] Please see Figure 1 and Figure 2 This invention provides an embodiment of an anti-counterfeiting structure for a hat body, which is disposed on the main body 1 of a rubber hat. It includes the main body 1, a tear-off film 2, and a tear-off head 3. A self-adhesive area 10 is provided on the outer wall of the main body 1. The tear-off film 2 and the tear-off head 3 are bonded to the self-adhesive area 10 of the main body 1 by adhesive. One end of the tear-off head 3 is a free end, forming a gripping part for holding. The other end of the tear-off head 3 is bonded and fixed to the tear-off film 2 and the main body 1. The surface of the tear-off head 3 is coated, printed, or hot-stamped with a first anti-counterfeiting material. The tear-off film 2 is loaded with a second anti-counterfeiting feature by printing or photolithography. The surface of the main body 1 is printed or hot-stamped with an anti-counterfeiting pattern 11, which penetrates the bonding area between the tear-off head 3 and the main body 1.
[0026] This embodiment provides a hat body anti-counterfeiting structure to prevent secondary alteration, which is disposed on the main body 1 of the rubber hat.
[0027] The tear-off film 2 and the tear-off head 3 are bonded to the self-adhesive area 10 by adhesive. One end of the tear-off head 3 is a free end, exposed on the surface of the main body 1 of the hat, forming a gripping part for the consumer to hold. The other end of the tear-off head 3 is bonded and fixed to the tear-off film 2 and the main body 1 of the hat.
[0028] The surface of the main body 1 of the hat is provided with an anti-counterfeiting pattern 11 by printing. The anti-counterfeiting pattern 11 penetrates the bonding area between the tear-off head 3 and the main body 1 of the hat. That is, part of the anti-counterfeiting pattern 11 is covered by the tear-off head 3, and the other part is exposed on the surface of the main body 1 of the hat.
[0029] When a consumer needs to open the cap, they pinch the gripping part of the tear-off head 3 and rotate and pull it. Under the action of tearing force, the tear-off head 3 is peeled off from the cap body 1 and the tear film 2 at the same time. During this process: part of the anti-counterfeiting pattern 11 on the surface of the main body 1 of the hat is taken away by the tearing head 3, and the remaining part remains on the surface of the main body 1 of the hat, forming an incomplete pattern that cannot be restored. The second anti-counterfeiting feature inside the tear film 2 is damaged between layers. After peeling, the pattern on the tearing head 3 and the main body 1 of the hat is damaged due to peeling.
[0030] Through the aforementioned multiple destructive mechanisms, once the cap is opened, all anti-counterfeiting features are irreversibly destroyed, completely eliminating the possibility of the cap being illegally transferred or reused.
[0031] Through the above steps, the present invention integrates the opening function and anti-counterfeiting function of the cap into the same device. When the consumer pinches the tear head 3 and rotates to open the cap, the tear head 3, the tear film 2 and the cap body 1 will inevitably separate. This process destroys the anti-counterfeiting features loaded on the surface of the tear head 3 and inside the tear film 2, thus solving the problem of the cap being reused.
[0032] Example 2: Please see Figure 1 and Figure 2 This embodiment is an improvement on embodiment 1. In this embodiment, the main body 1 of the cap is made of a material selected from polyethylene terephthalate, polypropylene, polyvinyl chloride, polyethylene, polycarbonate, heat-shrinkable polyethylene terephthalate, heat-shrinkable polyvinyl chloride, or polyolefin plastic optical material. The self-adhesive area 10 is located at the rolled seam of the main body 1 of the cap, and the adhesive width is 2.5mm to 5.0mm. The tear-off film 2 is set on the outer or inner surface of the main body 1 of the cap, and the pinching part of the tear-off head 3 is exposed on the surface of the main body 1 of the cap.
[0033] Material selection for the main body of the cap: Polyethylene terephthalate: high transparency, good heat shrinkage performance; Polyvinyl chloride: low cost, wide heat shrinkage temperature range; Polyethylene: good flexibility, low temperature resistance; Polycarbonate: high mechanical strength, good heat resistance; Heat shrinkable polyvinyl chloride: high shrinkage rate, tight fit; Polyolefin plastic optical material: extremely high transparency, good optical effect.
[0034] In this embodiment, the main body 1 of the cap is made of heat-shrinkable polyethylene terephthalate (PET). This choice is mainly based on its comprehensive performance advantages in cap applications. PET has excellent heat-shrinkable properties, allowing it to adhere evenly and tightly to the bottle opening surface when heated, forming a good seal and effectively preventing liquid leakage or external contamination. Simultaneously, its high transparency allows the anti-counterfeiting pattern 11 and printed information applied to the surface or interior of the cap body 1 to be clearly displayed, facilitating consumer verification of authenticity by visual inspection or simple equipment during purchase. Furthermore, the material also possesses good mechanical strength and flexibility, ensuring it is not easily damaged during transportation and storage, and can be easily torn along the designed path when opened by the consumer, balancing the integrity of the packaging with ease of use.
[0035] Example 3: Please see Figure 4 This embodiment is an improvement on embodiment 1. In this embodiment, the tearing head 3 can be made of one of the following materials: aluminum foil, plastic, or aluminum-plastic composite material. The tearing head 3 has a multi-layer composite structure.
[0036] In this embodiment, the tear-off head 3 adopts a four-layer composite structure design. Its surface is coated with a first anti-counterfeiting material, such as a holographic anti-counterfeiting pattern 11 or a laser mark, by hot stamping. This design places the anti-counterfeiting information at the most intuitive and visible level. Consumers can conduct preliminary verification of authenticity by observing the laser effect or holographic image before opening the product. The adjacent protective layer plays a key barrier role, effectively blocking the erosion of moisture and oxygen in the air, preventing the inner layer from oxidizing and darkening, and also buffering external mechanical impacts to protect the inner aluminum foil from scratches or damage during transportation and storage, ensuring the overall structural integrity and appearance of the tear-off head 3.
[0037] Example 4: Please see Figure 3 This embodiment is an improvement on embodiment 1. In this embodiment, the tear film 2 has a double-layer structure, which includes a support layer 4 and a graphic information layer 5 from the inside to the outside. The graphic information layer 5 constitutes the second anti-counterfeiting feature.
[0038] In this embodiment, the tear-off film 2 adopts a double-layer composite structure design, consisting of a support layer 4 and a graphic information layer 5 from the inside out. The graphic information layer 5 is loaded with a second anti-counterfeiting feature through a high-precision printing process. These features can be microtext, anti-counterfeiting codes, or optically variable patterns. These fine anti-counterfeiting elements are clearly identifiable under normal conditions, making it easy for consumers to verify authenticity.
[0039] When the consumer pinches the tear head 3 and rotates to open the cap, the tearing force is transmitted to the tear film 2 through the adhesive interface. Because the interlayer bonding strength between the support layer 4 and the graphic information layer 5 is precisely controlled to be lower than the strength of other adhesive interfaces, during the tearing process, the interlayer separation and damage between the graphic information layer 5 and the support layer 4 occurs first. This damage mechanism has the following advantages: First, interlayer damage is irreversible physical damage. Unlike cases where the graphic information layer may peel off completely from the adhesive interface, the graphic information layer 5 will be torn or undergo irreversible deformation, resulting in the shrinkage of the loaded layer. The text, anti-counterfeiting codes, and other information are completely destroyed and cannot be restored by re-adhesion or heating. Secondly, this damage occurs inside the tear film 2, so even if counterfeiters attempt to repair it from the outside, they cannot restore the damaged internal information layer structure. Furthermore, anti-counterfeiting features such as optically variable patterns undergo permanent changes in optical properties during the separation of layers, further enhancing the anti-counterfeiting effect. This design ensures that once the cap is legally opened, its anti-counterfeiting features will inevitably suffer irreversible damage, completely eliminating the possibility of the cap being reused after being completely peeled off from a physical perspective.
[0040] Example 5: Please see Figure 1 and Figure 2This embodiment is an improvement on embodiment 1. In this embodiment, the bonding strength between the tear film 2 and the main body 1 of the cap is greater than the bonding strength between the inner layers of the tear film 2, so as to ensure that the inside of the tear film 2 is damaged when it is torn. The bonding strength between the tear head 3 and the tear film 2 is equal to the bonding strength between the tear film 2 and the main body 1 of the cap.
[0041] In this embodiment, to ensure the reliability and irreversibility of anti-counterfeiting damage, a precise gradient design was implemented for the strength of each adhesive interface. Specifically, the adhesive strength between the tear-off head 3 and the tear film 2 was set to the highest, the adhesive strength between the tear film 2 and the main body 1 of the hat was the next highest, and the bonding strength between the graphic information layer 5 inside the tear film 2 and the support layer 4 was controlled to the lowest. The logic of this strength gradient is that when the consumer pinches the tear-off head 3 and applies tearing force, the pulling force will be transmitted along the path of "tear-off head 3 - tear film 2 - main body 1 of the hat". Since the adhesive force between the tear-off head 3 and the tear film 2 is the strongest, the two will not separate. Although the adhesive force between the tear film 2 and the main body 1 of the hat is relatively strong, in terms of the order of force application, the damage will occur first at the weakest mechanical link - that is, the interlayer bonding inside the tear film 2.
[0042] The advantages of this design are mainly reflected in three aspects. First, it ensures the inevitability of anti-counterfeiting damage: since the damage point is precisely locked between the graphic information layer 5 carrying anti-counterfeiting information and the support layer 4, as long as the cap is opened, the internal graphic information layer 5 will inevitably tear or separate, resulting in permanent damage to anti-counterfeiting features such as microtext and anti-counterfeiting codes, avoiding the possibility of complete peeling of the anti-counterfeiting layer due to separation of the adhesive interface. Second, it eliminates the possibility of secondary use and repair: even if counterfeiters try to separate the components by heating or using solvents, this physical damage that occurs inside the material is irreparable—the torn information layer cannot be healed, and the damaged optical pattern cannot be regenerated, completely blocking the restoration path from a physical structure perspective. Third, it optimizes the balance between opening experience and anti-counterfeiting reliability: by controlling the intensity gradient, it ensures that consumers will not have difficulty operating due to excessive adhesion when opening normally (because the damage point is clear and the resistance is controllable), and also ensures that when opening abnormally (such as attempting to peel off the whole), the anti-counterfeiting layer will be damaged before the adhesive interface, achieving a dual optimization of user experience and anti-counterfeiting performance.
[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
