Description

Technical Field

[0001] This application relates to the field of container packaging technology, and in particular to an anti-counterfeiting bottle cap. Background Technology

[0002] The market is flooded with expensive alcoholic beverages, and counterfeiting high-end brands can generate huge profits. Due to current technological limitations, criminals can remove bottle caps for reuse. As a result, counterfeiters frequently use methods such as "high-temperature cap removal," "bottom-cap removal," and "packaging material recycling" to produce counterfeit products. This has led to a proliferation of counterfeiters filling bottles with non-original products and increasingly reselling original bottles, severely damaging the reputation of alcohol manufacturers.

[0003] Criminals exploit the weaknesses of plastic parts, such as poor strength, susceptibility to high-temperature deformation, and easy detachment of the inner and outer plastic parts. They bake the bottle cap at high temperatures, then pull it off or simply lift it off entirely from the bottom, leaving no obvious damage to the cap's appearance. They then fill the bottle with substandard liquor, repackage it, and sell it for exorbitant profits. To address this issue, there is an urgent need to design an anti-counterfeiting bottle cap that can prevent its reuse for counterfeiting. Summary of the Invention

[0004] Based on this, it is necessary to address the issue of counterfeiting bottle caps through reuse by providing an anti-counterfeiting bottle cap comprising: an outer sleeve, a lower sleeve, and a limiting ring. The outer sleeve has a first internal cavity axially extending through the top and bottom of the outer sleeve. A fixing groove and a limiting gap are provided on the inner wall of the outer sleeve. The lower sleeve is provided with a claw and a fixing platform. The claw is used to engage with a target object, and the fixing platform and the fixing groove are engaged to lock the outer sleeve and the lower sleeve. The limiting ring is provided with a limiting structure, which extends into the limiting gap when the fixing groove and the fixing platform are engaged to restrict the relative rotation between the outer sleeve and the lower sleeve.

[0005] In one embodiment, the inner side of the outer casing is further provided with a first fixing element and a second fixing element. The first fixing element is used to limit the fixing platform in a first direction, and the second fixing element is used to limit the fixing platform in a second direction. The first fixing element and the second fixing element cooperate to form the fixing groove.

[0006] In one embodiment, the first fixing element extends along a first reference line, the second fixing element extends along a second reference line, the first reference line and the second reference line are perpendicular, and one end of the first fixing element and one end of the second fixing element are connected.

[0007] In one embodiment, the shape of the fixing groove formed by the first fixing element and the second fixing element matches the shape of the fixing platform.

[0008] In one embodiment, the length of the limiting structure is equal to the length of the limiting gap.

[0009] In one embodiment, the material of the lower sleeve is selected as a high-temperature resistant and high-strength material.

[0010] In one embodiment, it further includes: an outer cover, the outer cover having a second internal cavity axially extending through the bottom of the outer cover, the outer cover having a first snap-fit ​​component, and the outer cover being disposed on the top of the outer cover.

[0011] In one embodiment, it further includes: an inner cover disposed in the second internal cavity, the inner cover having a second snap-fit ​​component, the first snap-fit ​​component and the second snap-fit ​​component engaging to fix the outer cover and the inner cover, the inner cover having a third internal cavity axially penetrating the bottom of the inner cover.

[0012] In one embodiment, it further includes an inner sleeve disposed in the third internal cavity, the inner sleeve being connected to the inner cover.

[0013] In one embodiment, it further includes an inner plug, at least a portion of which is disposed in the first internal cavity, the inner plug being connected to the inner sleeve, and the inner plug being disposed inside the target object.

[0014] This application provides an anti-counterfeiting bottle cap with a fixing groove on the outer sleeve. The fixing groove and the fixing platform on the lower sleeve cooperate to fix the cap. The lower sleeve is also provided with a claw for locking the glass bottle, so that the bottle cap is firmly fixed on the glass bottle. When the bottle cap is pulled off by high temperature, the bottle mouth is damaged or the appearance of the outer part is damaged, indicating to the consumer that it has been opened, preventing the recycling of packaging materials, etc., and achieving the purpose of preventing counterfeiting.

[0043] See Figure 1 , Figure 1 This diagram illustrates the structure of an anti-counterfeiting bottle cap according to an embodiment of this application. The anti-counterfeiting bottle cap provided in this embodiment includes: an outer sleeve 1000, a lower sleeve 2000, and a limiting ring 3000. The outer sleeve 1000 has a first internal cavity axially penetrating the top and bottom of the outer sleeve 1000. A fixing groove 1100 and a limiting gap 1200 are provided on the inner wall of the outer sleeve 1000. The lower sleeve 2000 is provided with a claw 2200 and a fixing... The fixed platform 2100 and the claw 2200 are used to engage the target object. The fixed platform 2100 and the fixed groove 1100 are engaged to lock the outer sleeve 1000 and the lower sleeve 2000. The limiting ring 3000 is provided with a limiting structure 3100. The limiting mechanism is used to extend into the limiting gap 1200 when the fixed groove 1100 and the fixed platform 2100 are engaged to limit the relative rotation between the outer sleeve 1000 and the lower sleeve 2000.

[0044] In this embodiment, this application addresses the shortcomings of current bottle cap plastic parts, such as poor strength, easy deformation at high temperatures, and easy detachment of the inner and outer plastic parts. After the bottle cap is baked at high temperature, it is easy to pull it off or directly pull it off by grabbing the bottom of the bottle cap without any obvious damage to the appearance of the bottle cap, which can be exploited by criminals for profit. The present application provides an anti-counterfeiting bottle cap. The anti-counterfeiting bottle cap is made of high temperature resistant and high strength material, and the inner and outer parts are newly designed so that the inner and outer parts are connected together. When the bottle cap is heated and pulled off, the bottle mouth will be damaged or the appearance of the outer part of the bottle cap will be obviously damaged, so as to indicate to consumers that the bottle cap has been opened, preventing the recycling of packaging materials, etc., and thus preventing the problem of secondary use for counterfeiting.

[0045] In this embodiment, the anti-counterfeiting bottle cap provided in this application includes an outer sleeve 1000. The outer sleeve 1000 has a first internal cavity inside. The first internal cavity extends through the bottom and top of the outer sleeve 1000 along its axial direction. It is used to cooperate with other components in the anti-counterfeiting bottle cap provided in this application to fix the outer sleeve 1000 to the mouth of the glass bottle 8000.

[0046] In current technology, the conventional bottle cap outer sleeve 1000 has a locking mechanism. However, the locking mechanism is limited by factors such as mold and pressing method, resulting in a small shape, shallow depth, and small mating dimensions. This cannot meet the requirement of damaging the bottle mouth during the bottle cap being pulled off, nor can it meet the pulling force requirement for damaging the appearance. Therefore, the anti-counterfeiting bottle cap provided in this application has a new design regarding the mating method between the outer sleeve 1000 and the lower sleeve 2000. Specifically, the inner wall surface of the outer sleeve 1000 is provided with a fixing groove 1100, and the outer wall surface of the lower sleeve 2000 is provided with a fixing platform 2100. The fixing groove 1100 and the fixing platform 2100 can cooperate with each other. After the fixing platform 2100 and the fixing groove 1100 are engaged and assembled, the outer sleeve 1000 and the lower sleeve 2000 can be locked, limiting the relative displacement between them. Under the new design provided in this application, the mating structure between the outer sleeve 1000 and the lower sleeve 2000 is a fixed fit, which is minimally restricted by factors such as molds and pressing methods. Compared with the current conventional mating structure, the fixed groove 1100 and the fixed platform 2100 have a wide shape, deep depth, and large mating size, which has obvious advantages. At the same time, when heating or pulling up the bottom, it can destroy the pulling force requirements of the bottle mouth and the outer parts, thereby preventing the problem of counterfeiting due to secondary use.

[0047] In this embodiment, the anti-counterfeiting bottle cap provided by this application also includes a lower sleeve 2000, which is disposed in the first internal cavity. A fixing platform 2100 is provided on the lower sleeve 2000. The fixing platform 2100 and a fixing groove 1100 formed inside the outer sleeve 1000 engage with each other to lock the lower sleeve 2000 inside the outer sleeve 1000, limiting the mutual rotation between the outer sleeve 1000 and the lower sleeve 2000. Simultaneously, a claw 2200 is also provided on the top of the lower sleeve 2000. In current conventional bottle caps, the fitting structure between the bottle cap and the bottle neck is the claw 2200 of the integral PET inner sleeve 6000. The 200 structure engages with the bottle neck. However, due to mold limitations, conventional bottle caps only have four locking claws 2200. Furthermore, PET material is prone to deformation at high temperatures, making the cap easily pulled off during high-temperature or bottom-pull operations, thus losing its anti-counterfeiting effect. This application provides a new design. In this application, the lower sleeve 2000, which engages with the bottle neck, is a single, internally disassembled unit made of a high-temperature resistant material. The locking claws 2200 are less affected by the mold, so the number of locking claws 2200 can be freely chosen within structural limits. In one embodiment, the top of the lower sleeve 2000 has eight locking claws 2200. Figure 3 As shown, the new design provided in this application is not easily deformed when the bottle is pulled at high temperature and from the bottom. The number of the 2200 claws that cooperate with the bottle mouth is more than the four of the conventional inner sleeve 6000. Therefore, it can fully meet the pulling force requirements that damage the bottle mouth and appearance, and achieve the purpose of preventing counterfeiting through secondary use.

[0048] In this embodiment, the anti-counterfeiting bottle cap provided by this application also includes a limiting ring 3000. During assembly, the limiting ring 3000 is disposed at the bottom of the outer sleeve 1000 and the lower sleeve 2000. A limiting structure 3100 is provided on the limiting ring 3000. After the outer sleeve 1000 and the lower sleeve 2000 are assembled together by the fixing platform 2100 and the fixing groove 1100, the limiting ring 3000 is aligned and pressed into the first internal cavity inside the outer sleeve 1000, thereby limiting the outer sleeve 1000 and the lower sleeve 2000 and preventing relative rotation between the lower sleeve 2000 and the outer sleeve 1000. Specifically, a limiting gap 1200 is provided inside the outer sleeve 1000. The limiting gap 1200 is disposed between the two fixing grooves 1100. When the limiting ring 3000 is aligned and pressed into the outer sleeve 1000, the limiting structure 3100 extends into the limiting gap 1200.

[0049] In one embodiment, the inner cavity of the outer casing 1000 is further provided with a first fixing element 1110 and a second fixing element 1120. The first fixing element 1110 is used to limit the fixing platform 2100 in a first direction, and the second fixing element 1120 is used to limit the fixing platform 2100 in a second direction. The first fixing element 1110 and the second fixing element 1120 cooperate to form the fixing groove 1100.

[0050] In this embodiment, the inner cavity of the outer jacket 1000 is provided with a first fixing element 1110 and a second fixing element 1120. The first fixing element 1110 and the second fixing element 1120 are approximately elongated. The first fixing element 1110 is arranged parallel to the axial direction of the outer jacket 1000, and the second fixing element 1120 is arranged perpendicular to the axial direction of the outer jacket 1000. One end of the first fixing element 1110 and one end of the second fixing element 1120 are connected. The area enclosed by the first fixing element 1110 and the second fixing element 1120 is a fixing groove 1100.

[0051] In one embodiment, the first fixing element 1110 extends along a first reference line, and the second fixing element 1120 extends along a second reference line. The first and second reference lines are perpendicular, and one end of the first fixing element and one end of the second fixing element are connected. In this embodiment, one end of the first fixing element 1110 and one end of the second fixing element 1120 are connected to form an "L"-shaped structure. The first fixing element 1110 extends along the first reference line, and the second fixing element 1120 extends along the second reference line. The first and second reference lines are perpendicular. In a preferred embodiment, the length of the first fixing element 1110 is greater than or equal to 10 mm, the length of the second fixing element 1120 is greater than or equal to 15 mm, the width of the second fixing element 1120 is greater than or equal to 1.4 mm, and the depth to which the second fixing element 1120 encloses the fixing platform 2100 is greater than or equal to 0.8 mm.

[0052] In one embodiment, the shape of the fixing groove 1100 formed by the first fixing element 1110 and the second fixing element 1120 matches the shape of the fixing platform 2100. In a preferred embodiment, the length of the fixing platform 2100 is greater than or equal to 15 mm, the width of the fixing platform 2100 is greater than or equal to 10 mm, and the protrusion height of the fixing platform 2100 is greater than or equal to 0.8 mm.

[0053] In one embodiment, the length of the limiting structure 3100 is equal to the length of the limiting gap 1200. In this embodiment, the limiting structure 3100 is disposed on the limiting ring 3000. When the limiting ring 3000 is aligned and pressed onto the bottom of the outer sleeve 1000, the limiting structure 3100 extends into the limiting gap 1200, thereby filling the limiting gap 1200. This prevents the fixing platform 2100 on the outer sleeve 1000 from moving out of the fixing groove 1100, thus restricting the relative rotation between the outer sleeve 1000 and the lower sleeve 2000. Therefore, to achieve the above effect, the size of the limiting structure 3100 must exactly fill the entire limiting gap 1200, so the length of the limiting structure 3100 is equal to the length of the limiting gap 1200.

[0054] In one embodiment, the lower sleeve 2000 is made of a high-temperature resistant and high-strength material. In this embodiment, the top of the lower sleeve 2000 is provided with a claw 2200, which is used to lock the bottle mouth. The claw 2200 needs to damage the bottle mouth when it is pulled up at high temperature. Therefore, the material of the lower sleeve 2000 needs to be a high-strength material to damage the bottle mouth with high strength. At the same time, since the bottle cap may be heated, if the temperature resistance of the lower sleeve 2000 is poor, it will soften or even melt during the heating process, and will not be able to damage the bottle mouth when it is pulled up. Therefore, in order to meet the pull-up force requirements of damaging the bottle mouth and appearance, the material of the lower sleeve 2000 needs to have high-temperature resistance, and thus the material of the lower sleeve 2000 needs to be selected as a high-temperature resistant and high-strength material.

[0055] In one embodiment, the device further includes an outer cover 4000, which has a second internal cavity extending axially through the bottom of the outer cover 4000. A first snap-fit ​​component 4100 is provided on the outer cover 4000, and the outer cover 4000 is disposed on the top of the outer casing 1000. In this embodiment, the anti-counterfeiting bottle cap provided by this application further includes an outer cover 4000, which is disposed on the top of the outer casing 1000 and connected to it. A second internal cavity is provided inside the outer cover 4000, extending axially through the bottom of the outer cover 4000. Simultaneously, a first snap-fit ​​component 4100 is also provided on the outer cover 4000 for snapping and fixing the outer cover 4000.

[0056] In one embodiment, it further includes: an inner cover 5000 disposed in the second internal cavity, the inner cover 5000 having a second snap-fit ​​component 5100, the first snap-fit ​​component 4100 and the second snap-fit ​​component 5100 engaging to fix the outer cover 4000 and the inner cover 5000, the inner cover 5000 having a third internal cavity, the third internal cavity axially penetrating the bottom of the inner cover 5000.

[0057] In this embodiment, the anti-counterfeiting bottle cap provided by this application further includes an inner cap 5000, which is disposed in a second internal cavity inside the outer cap 4000. A second snap-fit ​​component 5100 is provided on the inner cap 5000. The second snap-fit ​​component 5100 and the first snap-fit ​​component 4100 are snapped together to fix the inner cap 5000 in the second internal cavity inside the outer cap 4000. A third internal cavity is provided inside the inner cap 5000, which extends through the bottom of the inner cap 5000 along the axial direction of the inner cap 5000. When the anti-counterfeiting bottle cap provided by this application is assembled onto the bottle neck of the glass bottle 8000, the bottle neck of the glass bottle 8000 is accommodated in the third internal cavity.

[0058] In one embodiment, it further includes an inner sleeve 6000, which is disposed in the third internal cavity and connected to the inner cap 5000. In this embodiment, the anti-counterfeiting bottle cap provided by this application also includes an inner sleeve 6000, which is disposed in the third internal cavity and at the bottle mouth of the glass bottle 8000, and connected to the inner cap 5000.

[0059] In one embodiment, the device further includes an inner plug 7000, at least a portion of which is disposed in the first internal cavity. The inner plug 7000 is connected to the inner sleeve 6000, and the inner plug 7000 is disposed inside the target object. In this embodiment, the anti-counterfeiting bottle cap provided by this application also includes an inner plug 7000, at least a portion of which is disposed in the first internal cavity, and a portion of which extends beyond the top of the first internal cavity is disposed in a third internal cavity. The inner plug 7000 is connected to the inner sleeve 6000, and the inner plug 7000 is disposed inside the mouth of the glass bottle 8000.

[0060] The anti-counterfeiting bottle cap provided in this application is assembled as follows:

[0061] First, assemble the lower sleeve 2000 and the outer sleeve 1000 of this application. Specifically, align and press the fixing platform 2100 of the lower sleeve 2000 with the limiting gap 1200 of the outer sleeve 1000. Then, rotate the outer sleeve 1000 clockwise so that the fixing platform 2100 of the lower sleeve 2000 is twisted into the fixing groove 1100 of the outer sleeve 1000, completing the engagement between the fixing platform 2100 and the fixing groove 1100. At this time, the outer sleeve 1000 and the lower sleeve 2000 can still rotate relative to each other and are still in a movable state. Then, the limiting ring 3000... The positioning structure 3100 and the outer sleeve 1000 are aligned and pressed together through the limiting gap 1200. The limiting ring 3000 is pressed into the first internal cavity inside the outer sleeve 1000. Since the limiting structure 3100 is in the limiting gap 1200, the fixing platform 2100 cannot be disengaged from the fixing groove 1100, thereby restricting the relative rotation between the outer sleeve 1000 and the lower sleeve 2000. At this time, the outer sleeve 1000 and the lower sleeve 2000 cannot rotate relative to each other and are in an immobile state. Finally, the anti-counterfeiting bottle cap provided in this application is assembled onto the glass bottle 8000.

[0062] This application provides an anti-counterfeiting bottle cap. The outer sleeve 1000 is provided with a fixing groove 1100, which cooperates with the fixing platform 2100 provided on the lower sleeve 2000 for fixing. The lower sleeve 2000 is also provided with a claw 2200 for engaging the glass bottle 8000, firmly fixing the bottle cap on the glass bottle 8000. When the bottle cap is pulled off by high temperature or is maliciously pulled off as a whole, the bottle mouth is damaged or the appearance of the external part is damaged, indicating to the consumer that it has been opened, preventing the recycling of packaging materials, etc., and achieving the purpose of preventing counterfeiting.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
