Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and in particular to an anti-counterfeiting structure for packaging boxes. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products and are a very common item. Taking liquor packaging boxes as an example, by packaging liquor bottles in specially designed boxes, not only can the safety of the liquor bottles be ensured during transportation, but the quality of the liquor can also be significantly enhanced.

[0003] Currently, opening existing packaging boxes generally involves simply tearing off the outer packaging and removing the contents. However, for high-value goods such as liquor, there is an illegal practice of repairing opened boxes, refilling them with counterfeit liquor, and then reusing them. Therefore, designing appropriate anti-counterfeiting features on the packaging boxes could effectively reduce these illegal activities.

[0004] One current anti-counterfeiting structure involves placing an airbag and a spike structure inside the packaging box. When the box is opened, the spike structure punctures the airbag, releasing fluorescent powder inside. The presence of fluorescent powder is then observed to determine if the box has been opened. Specifically, Chinese patent document CN215362734U describes an anti-counterfeiting bottle cap. This cap includes a cap body and a bottle body, with the cap body detachably mounted at the bottle opening. It also includes a sealing plug and an anti-counterfeiting system. The sealing plug is located on the cap body and fits the bottle opening, while the anti-counterfeiting system is positioned between the cap body and the sealing plug. The anti-counterfeiting system includes a display mechanism, an execution mechanism, and a triggering mechanism. The display mechanism includes at least an airbag and a light-emitting element. The airbag is located on the cap body, and the light-emitting element is located inside the airbag. The airbag is positioned within an anti-counterfeiting groove on the cap body, and this groove secures the airbag in place. When the bottle is opened to drink the beverage, the mechanism is triggered as the cap detaches from the bottle, which in turn activates the control actuator. The actuator causes the air bladder to open, exposing the fluorescent powder inside to the anti-counterfeiting groove. Buyers can later check the fluorescent powder in the anti-counterfeiting groove and whether the air bladder is deflated by looking through the transparent top cap to determine whether the purchased item is recycled.

[0005] However, the fluorescent powder in the above-mentioned scheme may contaminate the items inside the packaging box after release. Secondly, sometimes the fluorescent powder cannot fully escape from the air bladder after it is punctured, making it difficult for users to accurately determine whether the fluorescent powder is present, thus losing its anti-counterfeiting effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an anti-counterfeiting structure for accurately determining whether a packaging box has been opened.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a packaging box anti-counterfeiting structure, including a pull ring seat and an air bladder. The air bladder is set in the air bladder cavity of the pull ring seat. The pull ring seat is provided with an opening trigger mechanism for puncturing the air bladder. The pull ring seat includes a pull ring seat cavity, which connects the air bladder cavity to the outside. The air bladder is filled with anti-counterfeiting liquid. The pull ring seat cavity is provided with an anti-counterfeiting structure that expands after contacting the anti-counterfeiting liquid.

[0008] Furthermore, the anti-counterfeiting structure includes compressed paper or compressed towel.

[0009] Furthermore, the anti-counterfeiting liquid includes water.

[0010] Furthermore, the triggering mechanism includes a pull ring and a pointed end fixedly disposed on the pull ring. The pull ring is rotatably disposed on the pull ring seat via a pin, and the pointed end is disposed in close contact with the airbag, facing the direction of the airbag.

[0011] Furthermore, the pull ring seat includes a pull ring groove that matches the shape of the pull ring, and the pull ring is positioned in the pull ring groove when the pull ring is in the closed state.

[0012] Furthermore, the tip is located on the top surface of the pull ring seat, the air bladder cavity is located at the geometric center of the top surface of the pull ring seat, and the extension direction of the pin is parallel to the top surface of the pull ring seat.

[0013] Furthermore, the pull ring groove is D-shaped.

[0014] Furthermore, the pull ring seat includes a mounting post, which is perpendicular to the top surface of the pull ring seat, and the side wall of the mounting post is surrounded by one-way locking teeth; it also includes a toothed disc fixedly mounted on the packaging box, with the one-way locking teeth and the toothed disc engaging in a one-way manner, the one-way engagement direction being the direction in which the mounting post is inserted into the toothed disc.

[0015] Furthermore, the gear disc includes gear disc retaining teeth, and the one-way retaining teeth are configured to engage with the gear disc in a one-way manner.

[0016] Furthermore, the outlet connecting the pull ring seat cavity to the outside is located between the gear plate and the top surface of the pull ring seat.

[0017] The beneficial effects of this invention are as follows: 1. After the airbag is punctured, the liquid anti-counterfeiting liquid inside the airbag will flow out from the puncture and into the airbag cavity. Since the pull ring seat cavity connects the airbag cavity to the outside, the anti-counterfeiting structure inside the pull ring seat cavity can come into contact with the anti-counterfeiting liquid inside the airbag cavity. The anti-counterfeiting structure, after contacting the anti-counterfeiting liquid, expands and overflows from the pull ring seat cavity to the outside, making it clearly observable and accurately indicating whether the airbag has been punctured. 2. Because the anti-counterfeiting structure uses safe materials such as compressed paper or compressed towels, there is no need to worry about contaminating the contents of the packaging box even after expansion, making it particularly suitable for food packaging and improving the safety of the packaged items. 3. The expanded compressed paper or compressed towel can remain in the pull ring seat cavity and its external area for a long time, avoiding the situation in traditional fluorescent powder solutions where the fluorescent powder is blown away, making it impossible to determine whether the packaging box has been opened. IV. The designed pull-ring structure achieves a linkage between the two actions of opening the packaging box and puncturing the air bladder, making the opening process very convenient. Its streamlined structure also significantly reduces the production cost of the anti-counterfeiting structure. V. In actual assembly, the toothed disc is fixed to the packaging box, and then the mounting post is inserted into the toothed disc through the one-way locking teeth of the pull-ring seat, thus completing the assembly and greatly improving production efficiency. This utility model is particularly suitable for packaging boxes of high-value products such as liquor. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 4The image shows one embodiment of the anti-counterfeiting structure of the packaging box. Figure 1 In this design, the toothed disc 5 is fixedly mounted on the corresponding packaging box and serves as the mounting base for the pull ring seat 2. In actual use, pulling the pull ring 1 and applying force away from the toothed disc 5 causes the mounting post 23 to move the toothed disc 5, tearing open the packaging box around it. After setting the toothed disc 5 in the pre-drilled hole on the packaging box, simply insert the mounting post 23 of the pull ring seat 2 into the corresponding hole on the toothed disc 5. Figure 2 As shown, due to the tooth shape design of the one-way locking tooth 24 and the toothed disc locking tooth 51, when the one-way locking tooth 24 is inserted downward into the toothed disc 5, it can smoothly pass through the toothed disc locking tooth 51, thus achieving downward insertion. However, when the one-way locking tooth 24 is pulled upward away from the toothed disc 5, a locking state is formed between the one-way locking tooth 24 and the toothed disc locking tooth 51, preventing the one-way locking tooth 24 from being pulled outward, thereby achieving a locking state between the one-way locking tooth 24 and the toothed disc locking tooth 51. This one-way locking relationship is the structural basis for assembling the one-way locking tooth 24 into the toothed disc 5, and also the structural basis for tearing open the packaging box around the toothed disc 5.

[0025] like Figures 1 to 4 As shown, the pull ring seat 2 consists of a top surface and a mounting post 23. The top surface is located at the top of the mounting post 23, and the top surface of the pull ring seat 2 is perpendicular to the mounting post 23. The pull ring seat 2 is T-shaped overall. One-way locking teeth 24 are arranged around the side wall of the mounting post 23, extending along the axial direction of the mounting post 23. The pull ring 1 is rotatably mounted on the pull ring seat 2 via pins 12 at both ends. Specifically, the pull ring seat 2 has corresponding pin holes 21, and the pins 12 are placed within the pin holes 21. The top surface of the pull ring seat 2 has a D-shaped pull ring groove 22, such as... Figure 2 As shown, when the pull ring 1 is not in the open state, it is positioned within the D-shaped pull ring groove 22, ensuring the flatness of the top surface of the pull ring seat 2 and preventing accidental contact that could puncture the airbag 3. The tip 11 is located on the pull ring 1. When the pull ring 1 is pulled to rotate around the pin 12, the tip 11 also rotates around the pin 12, thereby allowing the tip 11 to puncture the airbag 3 below it.

[0026] like Figures 2 to 4As shown, the airbag cavity 25 is located at the geometric center of the top surface of the pull ring seat 2. The pull ring seat cavity 26 extends in a direction perpendicular to the mounting post 23, and the pull ring seat cavity 26 connects the airbag cavity 25 on its left side with the outside on its right side. An airbag 3 is disposed within the airbag cavity 25. The airbag cavity 25 can be a thin-walled rubber airbag, and water is placed inside the airbag 3. The tip 11 faces the direction of the airbag 3. In this embodiment, the pull ring seat cavity 26 is rectangular, and compressed paper or a compressed towel is placed inside. After the compressed paper 4 or compressed towel is placed inside the rectangular pull ring seat cavity 26, it will not fall out of the pull ring seat cavity 26 due to friction. Taking the compressed paper 4 as an example, when the left side of the compressed paper 4 absorbs water from the airbag cavity 25, it will expand, and then expand to... Figure 4 The expanded compressed paper 41 is shown in its current state. The expanded compressed paper 41 extends significantly beyond the pull ring seat cavity 26, which is clearly visible to the naked eye. Figures 2 to 4 As shown, the outlet of the pull ring seat cavity 26 that connects to the outside is preferably located between the toothed disc 5 and the top surface of the pull ring seat 2. This can prevent moisture generated outside from causing the compressed paper 4 to expand, thus causing the anti-counterfeiting effect to fail and effectively protecting the compressed paper 4.

[0027] As 1 to Figure 4 As shown, the startup process is as follows. First, as... Figure 2 As shown, the tip 11 is positioned towards the airbag 3, but at this point, the tip 11 does not cause the airbag 3 to deform. Subsequently, as... Figure 3 As shown, pulling the ring 1 rotates it around the pin 12, causing the tip 11 to press downwards and deform the airbag 3. However, the pressure generated by the tip 11 is not enough to rupture the airbag 3, and the water level 31 inside the airbag 3 rises relatively due to the deformation. Finally, as... Figure 4 As shown, the pressure generated by the tip 11 causes a rupture 32 in the airbag 3. Water flows out from the rupture 32 and is initially stored in the airbag cavity 25 outside the airbag 3. Then, the compression paper 4 installed in the pull ring seat cavity 26 on the right side of the airbag cavity 25 expands upon contact with water, eventually expanding to... Figure 4 The state of the compressed paper 41 after expansion, as shown, is clearly protruding outside the pull ring seat cavity 26. This indicates that the airbag 3 has been punctured and the pull ring 1 has been pulled up, thus achieving the corresponding anti-counterfeiting judgment.
