Technical Field

[0001] The present application relates to the technical field of food packaging, and in particular to an anti-counterfeiting bottle cap and a container bottle. Background Art

[0002] Bottle caps are a crucial component of food and beverage packaging, serving as the first point of contact for consumers. They maintain a tight seal around the contents, while also providing tamper-evident protection and enhanced safety. Consequently, they are widely used in bottled products. As an upstream industry for the food, beverage, alcohol, chemical, and pharmaceutical industries, they are a key component of bottle container packaging.

[0003] Existing bottle caps typically include a security flap structure that is trapped within a security groove, preventing irreversible damage when the user pulls or twists the bottle cap, thereby achieving anti-counterfeiting purposes. However, during the assembly process, precisely pressing the security flap into the security groove requires specific skills and strength, which is difficult to achieve reliably through mechanical means. This makes automated bottle cap production impossible, severely limiting production efficiency. Summary of the Invention

[0015] In one embodiment, the end of the lower sleeve away from the upper cover is configured as a thin-walled structure, so that the end of the lower sleeve away from the upper cover can be broken when pried up by an external force.

[0016] In one embodiment, the wall thickness W of the thin-walled structure is 0.6 mm to 0.7 mm.

[0017] A container bottle comprises a bottle body and an anti-counterfeiting bottle cap as described above, wherein the lower sleeve of the anti-counterfeiting bottle cap is clamped on the bottle mouth of the bottle body.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0036] like Figures 1 to 3 As shown, an embodiment of the present application provides an anti-counterfeiting bottle cap 10, which includes an upper cover 100 and a lower cover 200; the lower cover 200 can be clamped on the bottle mouth of the target bottle body and snap-fitted with the upper cover 100; wherein, as shown in FIG. Figure 4 As shown, the upper cover 100 is provided with an anti-counterfeiting groove 110, and the lower cover 200 is provided with an anti-counterfeiting flap 210. The anti-counterfeiting flap 210 is accommodated in the anti-counterfeiting groove 110 and can break when the upper cover 100 is pulled or twisted. Of course, in other embodiments, the upper cover 100 is provided with the anti-counterfeiting flap 210, and the lower cover 200 is provided with the anti-counterfeiting groove 110.

[0037] The anti-counterfeiting bottle cap 10 can be used in container bottles involved in the fields of food, beverage, wine, chemical industry, pharmaceutical industry, etc. By pulling or twisting the upper cover 100 of the anti-counterfeiting bottle cap 10, the anti-counterfeiting flap 210 can be irreversibly damaged to achieve the purpose of anti-counterfeiting.

[0038] In order to be able to destroy the anti-counterfeiting flap 210 when screwing and when pulling, it is necessary to design the structure of the anti-counterfeiting flap 210 and the anti-counterfeiting groove 110 accordingly, so that the anti-counterfeiting groove 110 can limit the anti-counterfeiting flap 210 in the axial direction of the anti-counterfeiting bottle cap 10, and stop the anti-counterfeiting flap 210 when the upper cover 100 is pulled, thereby causing damage to the anti-counterfeiting flap 210; it can also limit the anti-counterfeiting flap 210 in the circumferential direction of the anti-counterfeiting bottle cap 10, so that the anti-counterfeiting groove 110 can limit the anti-counterfeiting flap 210 in the circumferential direction of the anti-counterfeiting bottle cap 10, and stop the anti-counterfeiting flap 210 when the upper cover 100 is screwed, thereby causing damage to the anti-counterfeiting flap 210.

[0039] The anti-counterfeiting groove 110 is usually set as a T-shaped groove, such as Figure 4 As shown, it may include a first groove portion 111 and a second groove portion 112 that are connected. The width of the first groove portion 111 along the circumference of the anti-counterfeiting bottle cap 10 is greater than the width of the second groove portion 112 along the circumference of the anti-counterfeiting bottle cap 10. The space surrounded by the side of the second groove portion 112 away from the first groove portion 111 constitutes the notch of the anti-counterfeiting groove 110. Correspondingly, the anti-counterfeiting flap 210 is also configured as a T-shaped flap, as shown in FIG. Figure 4 As shown, the anti-counterfeiting bottle cap 10 may include a first petal portion 211 and a second petal portion 212 connected to each other. The width of the first petal portion 211 along the circumferential direction of the anti-counterfeiting bottle cap 10 is greater than the width of the second petal portion 212 along the circumferential direction of the anti-counterfeiting bottle cap 10. The first petal portion 211 constitutes the free end of the anti-counterfeiting petal 210 and is accommodated in the first groove portion 111, and the second petal portion 212 is accommodated in the second groove portion 112. It should be noted that the free end of the anti-counterfeiting petal 210 refers to the end of the anti-counterfeiting petal 210 that is away from the lower sleeve 200 and is not connected to the lower sleeve 200.

[0040] Through the cooperation between the T-shaped flap and the T-shaped groove, the anti-counterfeiting groove 110 can limit the anti-counterfeiting flap 210 in the axial direction of the anti-counterfeiting bottle cap 10 and limit the anti-counterfeiting flap 210 in the circumferential direction of the anti-counterfeiting bottle cap 10.

[0041] However, during the assembly of the bottle cap 10, the first petal portion 211 with a larger width in the anti-counterfeiting petal 210 needs to pass through the second groove portion 112 with a smaller width in the anti-counterfeiting groove 110 before it can enter the first groove portion 111 with a larger width in the anti-counterfeiting groove 110. Considering that the width of the first petal portion 211 is greater than the width of the second groove portion 112, specific skills and strength are required to pass the first petal portion 211 through the second groove portion 112 and press it into the first groove portion 111, which is difficult to achieve stably through mechanical means, resulting in the inability to implement automated production of the bottle cap 10, which seriously restricts production efficiency.

[0042] In this regard, the present application further improves the structure of the upper cover 100 and the lower cover 200, such as Figure 4 and Figure 5As shown, the upper cover 100 is further provided with a first assembly bevel 120, and the lower cover 200 is also provided with a corresponding second assembly bevel 220. The first assembly bevel 120 is provided at the free end of the security flap 210, and the second assembly bevel 220 is adjacent to the notch of the security groove 110 and can cooperate with the first assembly bevel 120 to enable the security flap 210 to be press-fitted from the notch of the security groove 110 into the security groove 110. When the lower cover 200 is press-fitted upward onto the upper cover 100, the second assembly bevel 220 on the security flap 210 can slide along the first assembly bevel 120 on the upper cover 100 until the first flap portion 211 of the security flap 210 slides into the first groove portion 111 of the security groove 110. Of course, the upper cover 100 can also be press-fitted downward onto the lower cover 200.

[0043] The cooperation between the first assembly bevel 120 and the second assembly bevel 220 can guide the anti-counterfeiting flap 210 when it is pressed into the anti-counterfeiting groove 110, so that the anti-counterfeiting flap 210 can be smoothly pressed into the anti-counterfeiting groove 110. No special skills or strength are required to press the anti-counterfeiting flap 210 into the anti-counterfeiting groove 110, and a high-speed fully automatic assembly machine can be used for production, greatly reducing the production manpower requirements. It can be seen that the anti-counterfeiting bottle cap 10 provided by the present application can achieve an anti-pullout effect while implementing automated production and assembly of the bottle cap 10.

[0044] In some embodiments of the present application, the first petal 211 has a fourth surface facing away from the central axis of the anti-counterfeiting bottle cap 10, and the fourth surface has a marking area for indicating the opening direction of the bottle cap 10. The user can open or close the anti-counterfeiting bottle cap 10 according to the indication of the marking area.

[0045] Among them, relevant identifiers are usually set in the identification area by spraying, sticking, etc., such as Chinese characters with opening and closing arrows.

[0046] like Figure 5 As shown, in some embodiments of the present application, the first petal portion 211 further has a first surface 211a facing the central axis of the anti-counterfeiting bottle cap 10, and the first assembly bevel 120 is provided on the first surface 211a. The distances between the first assembly bevel 120 and the second assembly bevel 220 and the central axis of the anti-counterfeiting bottle cap 10 gradually decrease along the direction from the upper cover 100 to the lower cover 200. Providing the first assembly bevel 120 on the inner surface of the first petal portion 211 (i.e., the first surface 211a facing the central axis of the anti-counterfeiting bottle cap 10) eliminates the need for the identification area and the first assembly bevel 120 to be located on the outer surface of the first petal portion 211 (i.e., the second surface 211b facing away from the central axis of the anti-counterfeiting bottle cap 10). This prevents the identifier on the identification area from being scratched by the second assembly bevel 220 when the first assembly bevel 120 slides along the second assembly bevel 220 to achieve the pressing of the anti-counterfeiting petal 210.

[0047] Continue to see Figure 5In one embodiment, the first flap 211 further includes a second surface 211b proximate to the second flap 212 and a third surface 211c opposite the second surface 211b. The first assembly bevel 120 extends from the third surface 211c toward the second surface 211b and has a first spacing therebetween. When the anti-counterfeit flap 210 is pressed together, the junction between the first flap 211 and the second flap 212 (i.e., the second surface 211b of the first flap 211 proximate to the second flap 212) becomes a stress point. To prevent the junction between the first flap 211 and the second flap 212 from being crushed due to weak stress, the present application provides a first spacing between the first assembly bevel 120 and the second surface 211b to ensure stress strength at the junction between the first flap 211 and the second flap 212.

[0048] When the anti-counterfeit flap 210 is pressed together, the junction of the first groove portion 111 and the second groove portion 112 (i.e., the first groove surface 111a of the first groove portion 111 close to the second groove portion 112) is also a force point. In order to prevent the junction of the first groove portion 111 and the second groove portion 112 from being crushed due to weak force strength, as shown in FIG. Figure 5 As shown, in one embodiment, the first groove portion 111 has a first groove surface 111a adjacent to the second groove portion 112, and a second spacing is provided between the second assembly slope 220 and the first groove surface 111a. The second spacing also ensures sufficient strength at the junction of the first groove portion 111 and the second groove portion 112. When the upper cover 100 is pulled, the sufficient strength at the junction of the first groove portion 111 and the second groove portion 112 allows the anti-counterfeit flap 210 to be effectively destroyed.

[0049] In order to enable the anti-counterfeit flap 210 to break when the upper cover 100 is pulled, in one embodiment, as shown in FIG. Figure 4 As shown, the second flap portion 212 has a hollow area 212a. The provision of the hollow area 212a can reduce the strength of the anti-counterfeiting flap 210, allowing the anti-counterfeiting flap 210 to break when the upper cover 100 is pulled. It should be noted that the force required to press the anti-counterfeiting flap 210 into the anti-counterfeiting groove 110 is less than the force required to cause the anti-counterfeiting flap 210 to break when the upper cover 100 is pulled. The provision of the hollow area 212a does not affect the pressing of the anti-counterfeiting flap 210. That is, when the anti-counterfeiting flap 210 is pressed, the anti-counterfeiting flap 210 will not collapse due to the hollow area 212a.

[0050] like Figure 1 As shown, in some embodiments of the present application, a first labeling plane 130 is provided on one side of the upper cover 100 close to the lower cover 200, and a second labeling plane 230 is provided on one side of the lower cover 200 close to the upper cover 100. The second labeling plane 230 is aligned with the first labeling plane 130 in the axial direction of the anti-counterfeiting bottle cap 10 to form an anti-counterfeiting labeling area. Figure 6The anti-counterfeiting label 30 (i.e., anti-transfer label) can be placed on the anti-counterfeiting label area formed by the first labeling plane 130 and the second labeling plane 230. When the upper cover 100 is screwed, the anti-counterfeiting label 30 will be torn, thereby achieving the purpose of anti-counterfeiting.

[0051] The area of ​​the anti-counterfeiting label area can be greater than or equal to 400mm 2 , for example 400mm 2 , 450mm 2 , 500mm 2 The larger labeling surface allows the anti-counterfeiting bottle cap 10 with complex patterns to also adopt a high-precision positioning labeling system with an anti-transfer label to achieve full-process automated labeling.

[0052] like Figure 7 and Figure 8 As shown, in some embodiments of the present application, the end of the lower sleeve 200 away from the upper cover 100 is provided with a thin-walled structure 240, so that when the end of the lower sleeve 200 away from the upper cover 100 is pried up by an external force, it will break. Providing the end of the lower sleeve 200 away from the upper cover 100 with a thin-walled structure 240 can reduce the strength of the end of the lower sleeve 200 away from the upper cover 100. Therefore, when the bottle cap 100 is pulled as a whole by the tool 20, the end of the lower sleeve 200 away from the upper cover 100 will break, thereby also achieving the purpose of anti-counterfeiting.

[0053] Optionally, the wall thickness W of the thin-walled structure 240 is set to 0.6 mm to 0.7 mm, for example, 0.6 mm, 0.62 mm, 0.64 mm, 0.66 mm, 0.68 mm, 0.7 mm, etc. By setting the wall thickness of the end of the lower sleeve 200 away from the upper cover 100 in this manner, the end of the lower sleeve 200 away from the upper cover 100 will break when the bottle cap is pulled as a whole, but the end of the lower sleeve 200 away from the upper cover 100 will not be damaged when the bottle cap 10 is clamped onto the target bottle.

[0054] In some embodiments of the present application, a micro-mark is further provided on the outside of the upper cover 100. The provision of the micro-mark makes it impossible for counterfeiters to detect it and to make a 100% imitation of the original bottle cap, thereby achieving the purpose of anti-counterfeiting.

[0055] In one embodiment, if Figure 9As shown, the end of the upper cover 100 away from the lower housing 200 is provided with multiple edges 140 spaced circumferentially, with one edge 140 being the smallest. This arrangement allows the upper cover 100 to have edges 140 of different lengths. This length difference is difficult for counterfeiters to detect. When counterfeiting, counterfeiters can set all edges 140 to the same length, making it impossible to 100% imitate the original bottle cap, thus achieving anti-counterfeiting purposes. Of course, in other embodiments, the miniature hidden mark can also be provided in other ways, such as by making the spacing between two adjacent edges 140 greater or smaller than the spacing between any other two adjacent edges 140.

[0056] In some embodiments of the present application, an anti-counterfeiting QR code (not shown in the drawings) is further provided on the top wall of the upper cover 100. After the user opens the bottle cap 10, he or she can scan the anti-counterfeiting QR code through a terminal device to confirm that the bottle cap has been opened, which also serves the purpose of anti-counterfeiting.

[0057] The anti-counterfeiting bottle cap 10 of the present application adopts four anti-counterfeiting technologies (i.e., anti-transfer label, micro-hidden label, QR code, and local + overall anti-pullout structure), which optimizes the anti-counterfeiting performance of the bottle cap 10.

[0058] In some embodiments of the present application, the present application further includes a decorative cover (not shown in the drawings), which is disposed outside the upper cover 100. The decorative cover mainly serves a decorative purpose.

[0059] The present application also optimizes the structure of the anti-counterfeiting bottle cap 10, simplifying the anti-counterfeiting system that can only be achieved by a traditional five-component bottle cap into a three-component integrated structure, thereby reducing the number of bottle cap components, lowering product production costs, and meeting the market demand for improving quality and efficiency.

[0060] On the other hand, an embodiment of the present application further provides a container bottle, which includes a bottle body and an anti-counterfeit bottle cap 10 as described in any one of the above items, and the lower sleeve 200 of the anti-counterfeit bottle cap 10 is clamped on the bottle mouth of the bottle body.

[0061] The anti-counterfeiting bottle cap 10 can be used in the fields of food, beverage, wine, chemical industry, pharmaceutical industry, etc. By pulling or twisting the upper cover 100 of the anti-counterfeiting bottle cap 10, the anti-counterfeiting flap 210 can be irreversibly damaged to achieve the purpose of anti-counterfeiting.

[0062] In order to be able to destroy the anti-counterfeiting flap 210 when screwing and when pulling, it is necessary to design the structure of the anti-counterfeiting flap 210 and the anti-counterfeiting groove 110 accordingly, so that the anti-counterfeiting groove 110 can limit the anti-counterfeiting flap 210 in the axial direction of the anti-counterfeiting bottle cap 10, and stop the anti-counterfeiting flap 210 when the upper cover 100 is pulled, thereby causing damage to the anti-counterfeiting flap 210; it can also limit the anti-counterfeiting flap 210 in the circumferential direction of the anti-counterfeiting bottle cap 10, so that the anti-counterfeiting groove 110 can limit the anti-counterfeiting flap 210 in the circumferential direction of the anti-counterfeiting bottle cap 10, and stop the anti-counterfeiting flap 210 when the upper cover 100 is screwed, thereby causing damage to the anti-counterfeiting flap 210.

[0063] The anti-counterfeiting groove 110 is usually set as a T-shaped groove, such as Figure 4 As shown, it may include a first groove portion 111 and a second groove portion 112 that are connected. The width of the first groove portion 111 along the circumference of the anti-counterfeiting bottle cap 10 is greater than the width of the second groove portion 112 along the circumference of the anti-counterfeiting bottle cap 10. The space surrounded by the side of the second groove portion 112 away from the first groove portion 111 constitutes the notch of the anti-counterfeiting groove 110. Correspondingly, the anti-counterfeiting flap 210 is also configured as a T-shaped flap, as shown in FIG. Figure 4 As shown, the anti-counterfeiting bottle cap 10 may include a first petal portion 211 and a second petal portion 212 connected to each other. The width of the first petal portion 211 along the circumferential direction of the anti-counterfeiting bottle cap 10 is greater than the width of the second petal portion 212 along the circumferential direction of the anti-counterfeiting bottle cap 10. The first petal portion 211 constitutes the free end of the anti-counterfeiting petal 210 and is accommodated in the first groove portion 111, and the second petal portion 212 is accommodated in the second groove portion 112. It should be noted that the free end of the anti-counterfeiting petal 210 refers to the end of the anti-counterfeiting petal 210 that is away from the lower sleeve 200 and is not connected to the lower sleeve 200.

[0064] Through the cooperation between the T-shaped flap and the T-shaped groove, the anti-counterfeiting groove 110 can limit the anti-counterfeiting flap 210 in the axial direction of the anti-counterfeiting bottle cap 10 and limit the anti-counterfeiting flap 210 in the circumferential direction of the anti-counterfeiting bottle cap 10.

[0065] However, during the assembly of the bottle cap 10, the first petal portion 211 with a larger width in the anti-counterfeiting petal 210 needs to pass through the second groove portion 112 with a smaller width in the anti-counterfeiting groove 110 before it can enter the first groove portion 111 with a larger width in the anti-counterfeiting groove 110. Considering that the width of the first petal portion 211 is greater than the width of the second groove portion 112, specific skills and strength are required to pass the first petal portion 211 through the second groove portion 112 and press it into the first groove portion 111, which is difficult to achieve stably through mechanical means, resulting in the inability to implement automated production of the bottle cap 10, which seriously restricts production efficiency.

[0066] In this regard, the present application further improves the structure of the upper cover 100 and the lower cover 200, such as Figure 4 and Figure 5As shown, the upper cover 100 is further provided with a first assembly bevel 120, and the lower cover 200 is also provided with a corresponding second assembly bevel 220. The first assembly bevel 120 is provided at the free end of the security flap 210, and the second assembly bevel 220 is adjacent to the notch of the security groove 110 and can cooperate with the first assembly bevel 120 to enable the security flap 210 to be press-fitted from the notch of the security groove 110 into the security groove 110. When the lower cover 200 is press-fitted upward onto the upper cover 100, the second assembly bevel 220 on the security flap 210 can slide along the first assembly bevel 120 on the upper cover 100 until the first flap portion 211 of the security flap 210 slides into the first groove portion 111 of the security groove 110. Of course, the upper cover 100 can also be press-fitted downward onto the lower cover 200.

[0067] The cooperation between the first assembly bevel 120 and the second assembly bevel 220 can guide the anti-counterfeiting flap 210 when it is pressed into the anti-counterfeiting groove 110, so that the anti-counterfeiting flap 210 can be smoothly pressed into the anti-counterfeiting groove 110. No special skills or strength are required to press the anti-counterfeiting flap 210 into the anti-counterfeiting groove 110, and a high-speed fully automatic assembly machine can be used for production, greatly reducing the production manpower requirements. It can be seen that the anti-counterfeiting bottle cap 10 provided by the present application can achieve an anti-pullout effect while implementing automated production and assembly of the bottle cap 10.

[0068] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0069] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
