Description

Technical Field

[0001] This utility model relates to the field of packaging anti-counterfeiting technology, and in particular to a bottle cap locking component for packaging anti-counterfeiting. Background Technology

[0002] Consumers' demand for convenient product authenticity verification is driving the continuous evolution of bottle cap anti-counterfeiting technology. Designs such as self-destructible anti-counterfeiting buckles and visually identifiable dynamic textures allow consumers to verify authenticity without specialized tools, transforming bottle caps from mere packaging components into a direct representation of brand trust.

[0003] Existing anti-counterfeiting technologies, such as self-destructible anti-counterfeiting buckles and sealed textures, essentially rely on the rigid interlocking of plastic or the fixing effect of adhesives to achieve irreversibility. However, these designs are not optimized for the thermal stability of materials: the plastic of ordinary anti-counterfeiting bottle caps is mostly made of polyethylene or polypropylene, which is prone to softening and deformation at temperatures of 60-100℃. The buckles, which originally relied on rigid support, will lose their locking ability, making it impossible to determine whether the bottle cap has been opened by observing the damage, thus losing the anti-counterfeiting function. Utility Model Content

[0004] To address the problem that self-destructing snap-on bottle caps in existing technologies easily soften and deform under heating, losing their locking and self-destructing capabilities and thus failing to prevent counterfeiting, this utility model provides a bottle cap locking component for packaging anti-counterfeiting.

[0005] The technical solution adopted in this utility model is:

[0006] A bottle cap locking assembly for anti-counterfeiting packaging includes an inner fastener and an outer rotating fastener. The outer rotating fastener is sleeved on the outside of the inner fastener. The inner fastener has a protruding fastening groove on its side wall and a ratchet fastening groove on its surface.

[0007] The inner wall of the external rotating fastener is provided with a protruding fastening part that mates with the protruding fastening groove, and the inner wall of the external rotating fastener is also provided with a fastening ratchet that mates with the ratchet fastening groove.

[0008] The protruding fastening part is used to move along the protruding fastening groove to the fastening position when the inner fastener and the outer rotating fastener rotate relative to each other. The ratchet is used to engage with the ratchet fastening groove when the inner fastener and the outer rotating fastener rotate relative to each other to the fastening position.

[0009] Furthermore, the protrusion fastening groove includes a first fastening groove and a second fastening groove, wherein the first fastening groove is disposed above the second fastening groove and communicates with the second fastening groove;

[0010] The first fastening groove is used for the protruding fastening part to be inserted and engaged, and then enters the second fastening groove through the first fastening groove.

[0011] Furthermore, a vertical limiting part is provided on the inner side wall of the external rotating fastener, and a limiting support part is provided on the inner fastener to cooperate with the vertical limiting part; the vertical limiting part is used to limit the movement of the inner fastener in the vertical direction when the inner fastener and the external rotating fastener rotate relative to each other to the fastening position, by cooperating with the limiting support part.

[0012] Furthermore, the external rotating fastener includes an outer support member and an inner metal ring. The inner metal ring is co-centered with the outer support member and fits against the inner wall of the outer support member. The protruding fastening part is disposed on the inner metal ring. The protruding fastening part is a metal fastening piece that protrudes in an inclined shape. The metal fastening piece is used to limit the movement of the inner fastener in the vertical direction.

[0013] Furthermore, the outer support member has an installation positioning hole corresponding to the position of the metal fastening piece. The installation positioning hole is used to align and position the installation position when the metal fastening piece is installed into the outer support member.

[0014] Furthermore, the protruding part fastening groove is provided in a direction inclined to the horizontal plane. The protruding part fastening groove is used to limit and guide the protruding fastening part through its inclined shape, so that the inner fastener and the outer rotating fastener move relative to each other in the vertical direction to form a height difference.

[0015] The beneficial effects of this utility model are:

[0016] The outer rotating fastener of this bottle cap locking assembly is sleeved on the outside of the inner fastener. When the bottle cap is opened, the two are locked by rotating relative to each other. When the outer rotating fastener is driven to rotate by external force, the protruding engaging part on the inner side wall of the outer rotating fastener will gradually move to the engaging position along the protruding engaging groove on the side wall of the inner fastener. At the same time, the engaging ratchet on the inner side wall of the outer rotating fastener will engage with the ratchet engaging groove on the surface of the inner fastener, so that it cannot rotate in the opposite direction to return to its original position, forming a double-engaging locking structure. This component breaks away from the single reliance on the rigidity of plastic. Compared to existing technologies where the plastic softens due to heat, resulting in insufficient rigidity and causing the buckle to disengage or the lock to fail, the component of this invention forms a double constraint lock through the engagement of the protruding engagement part and the protruding engagement groove, and the toothed engagement of the engagement ratchet and the ratchet engagement groove. Even if plastics such as polyethylene and polypropylene soften at 60℃-100℃, this structural engagement will not automatically disengage due to the decrease in material hardness and will still maintain the locked state. Consumers can intuitively judge whether the bottle cap has been opened by observing the relative position of the components and whether the engagement ratchet has been damaged by force.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] A bottle cap locking component for anti-counterfeiting packaging, such as Figures 1-6 As shown, it includes an inner fastener 1 and an outer rotating fastener 2. The outer rotating fastener 2 is sleeved on the outside of the inner fastener 1. The inner fastener 1 has a protruding engagement groove 11 on its side wall and a ratchet engagement groove 13 on its surface. The outer rotating fastener 2 has a protruding engagement part 21 on its inner side wall that cooperates with the protruding engagement groove 11, and a ratchet 22 on its inner side wall that cooperates with the ratchet engagement groove 13. The protruding engagement part 21 is used to move along the protruding engagement groove 11 to the engagement position when the inner fastener 1 and the outer rotating fastener 2 rotate relative to each other. The ratchet is used to engage with the ratchet engagement groove 13 when the inner fastener 1 and the outer rotating fastener 2 rotate relative to each other to the engagement position.

[0032] When the bottle cap locking assembly of this utility model is in operation, after the outer rotating fastener 2 is sleeved outside the inner fastener 1, the bottle cap is locked by the relative rotation of the inner fastener 1 and the outer rotating fastener 2 when the bottle cap is opened. The protruding engaging part 21 on the inner sidewall of the outer rotating fastener 2 will gradually move along the protruding engaging groove 11 on the sidewall of the inner fastener 1, and finally reach the engaging position. At the same time, the engaging ratchet 22 on the inner sidewall of the outer rotating fastener 2 will also rotate relative to the inner fastener 1 and form a tight engagement with the ratchet engaging groove 13 on the surface of the inner fastener 1. At this time, the engagement of the protruding engaging part 21 and the protruding engaging groove 11 prevents the outer rotating fastener 2 from moving up and down in the vertical direction and from continuing to twist with the inner fastener 1. The engagement of the ratchet 22 and the ratchet engaging groove 13 prevents the outer rotating fastener 2 from rotating back to its original position with the inner fastener 1. This eliminates the reliance on the single rigidity of the plastic part. Even if the plastic softens at the heating temperature, the double engaging structure can still maintain the locked state, ensuring that the bottle cap can be judged by observing the state of the engaging parts. This retains the convenience of identification without professional tools and avoids the problem of anti-counterfeiting failure caused by material softening.

[0033] Example 2

[0034] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 4 As shown, the protrusion fastening groove 11 includes a first fastening groove 111 and a second fastening groove 112. The first fastening groove 111 is disposed above the second fastening groove 112 and communicates with the second fastening groove 112. The first fastening groove 111 is used for the protrusion fastening part 21 to be inserted and engaged, and to enter the second fastening groove 112 through the first fastening groove 111.

[0035] In this embodiment, when the bottle cap locking assembly is in operation, the protruding fastening part 21 first inserts into the first fastening groove 111 on the side wall of the inner fastener 1. Guided by the first fastening groove 111, it then enters the second fastening groove 112 that communicates with it, completing the initial installation. This structure divides the protruding fastening groove 11 into the first fastening groove 111 and the second fastening groove 112 that are connected vertically, forming a step-by-step installation and fastening path, making the installation and movement of the protruding fastening part 21 more directional. This embodiment avoids the protruding fastening part 21 from shifting or misaligning during installation and movement, improving the stability and accuracy of the installation and movement process, and further enhancing the reliability of the locking structure. At the same time, the step-by-step installation and movement fastening path makes the installation and movement fastening smoother, improving efficiency for both manufacturing and use.

[0036] Example 3

[0037] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 5 , Figure 7As shown, a vertical limiting part 23 is provided on the inner side wall of the outer rotating fastener 2, and a limiting support part 15 that cooperates with the vertical limiting part 23 is provided on the inner fastener 1. The vertical limiting part 23 is used to limit the movement of the inner fastener 1 in the vertical direction by cooperating with the limiting support part 15 when the inner fastener 1 and the outer rotating fastener 2 rotate relative to each other to the fastening position.

[0038] In this embodiment, a vertical limiting part 23 is provided on the inner sidewall of the outer rotating fastener 2, and a corresponding limiting support part 15 is provided on the inner fastener 1. When the inner fastener 1 and the outer rotating fastener 2 rotate relative to each other to the fastening position, the vertical limiting part 23 of the outer rotating fastener 2 will contact and cooperate with the limiting support part 15 of the inner fastener 1. At this time, the vertical limiting part 23 will generate a vertical constraint force on the limiting support part 15, thereby restricting the movement of the inner fastener 1 in the vertical direction. This structure, through the cooperation of the vertical limiting part 23 and the limiting support part 15, further enhances the vertical position fixing effect of the inner fastener 1 and the outer rotating fastener 2, and avoids the displacement of the inner fastener 1 in the vertical direction due to external vibration or accidental external force, thereby affecting the stability of the engagement between the protruding fastening part 21 and the fastening groove, and between the ratchet and the ratchet fastening groove 13. During implementation, the positions of the vertical limiting part 23 and the limiting support part 15 need to be determined to ensure that they can be accurately matched when they are engaged, and that the structural strength of both parts meets the usage requirements to prevent deformation or damage during the limiting process.

[0039] Example 4

[0040] This embodiment is based on the foregoing embodiment. In this embodiment... Figures 1-2 , Figures 6-8 As shown, the outer rotating fastener 2 includes an outer support member 25 and an inner metal ring 26. The inner metal ring 26 is co-centered with the outer support member 25 and fits against the inner wall of the outer support member 25. A protruding fastening part 21 is provided on the inner metal ring 26. The protruding fastening part 21 is a metal fastening piece 27 that protrudes in an inclined shape. The metal fastening piece 27 is used to limit the movement of the inner fastener 1 in the vertical direction.

[0041] In a preferred embodiment, the outer support member 25 is provided with an installation positioning port 28 corresponding to the position of the metal fastening piece 27. The installation positioning port 28 is used to align and position the installation position when the metal fastening piece 27 is installed into the outer support member 25.

[0042] In this embodiment, the external rotating fastener 2 is designed as two parts: an outer support 25 and an inner metal ring 26. During assembly, the inner metal ring 26 is arranged concentrically with the outer support 25 and fits against the inner wall of the outer support 25. The protruding fastening part 21 is set as an inclined protruding metal fastening piece 27 and integrated on the inner metal ring 26 (the metal fastening piece 27 can be machined on the inner metal ring 26). At the same time, an installation positioning hole 28 corresponding to the position of the metal fastening piece 27 is opened on the outer support 25. When installing the metal fastening piece 27, the position is aligned by the installation positioning hole 28 to ensure that the metal fastening piece 27 can accurately cooperate with the first fastening groove 111 and the second fastening groove 112 of the inner fastener 1. During use, the metal fastening piece 27 moves synchronously with the inner metal ring 26 and the outer support 25, and moves along the groove direction of the second fastening groove 112 to the fastening position. The characteristics of the metal material limit the movement of the inner fastener 1 in the vertical direction. This embodiment further enhances the high-temperature resistance and structural strength of the protruding fastening part 21 through the inner metal ring 26 and the metal fastening piece 27. Even in high-temperature environments, the metal fastening piece 27 maintains a good limiting effect, while preventing the elastic deformation of the plastic part from causing the inner fastener 1 to separate from the outer rotating fastener 2. The mounting positioning port 28 ensures a more accurate installation position for the metal fastening piece 27. During implementation, it is necessary to ensure that the inner metal ring 26 fits tightly with the outer support 25 without gaps, and the tilt angle of the metal fastening piece 27 must be adapted to the groove depth of the second fastening groove 112 to prevent the metal fastening piece 27 from falling out of the groove.

[0043] Example 5

[0044] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 3 , Figure 4 As shown, the protruding part fastening groove 11 is provided in a direction inclined to the horizontal plane. The protruding part fastening groove 11 is used to limit and guide the protruding fastening part 21 by means of its inclined shape, so that the inner fastener 1 and the outer rotating fastener 2 move relative to each other in the vertical direction to form a height difference.

[0045] When the bottle cap is opened, external force drives the outer protective cap to rotate the outer rotating fastener 2. The protruding fastening part 21 moves along the second fastening groove 112, which is inclined to the horizontal plane. Due to the inclined nature of the second fastening groove 112, the inner fastener 1 and the outer rotating fastener 2 gradually move relative to each other in the vertical direction during rotation, forming a height difference. This continues until the protruding fastening part 21 reaches the fastening position. The limiting effect of the protruding fastening part 21 and the second fastening groove 112 prevents the inner fastener 1 and the outer rotating fastener 2 from moving vertically. Consumers can judge whether the bottle cap has been opened by observing the height difference formed by the bottle cap from the outside, which is more intuitive and convenient. This embodiment can be implemented in conjunction with the vertical limiting part 23 of embodiment 3 to make the locking in the height direction more stable and secure, further preventing counterfeiters from cracking the bottle cap locking assembly.

[0046] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
