Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bottle caps, in particular to a metal anti-pry ring of a bottle cap. Background Art
[0002] Currently, a large proportion of counterfeit alcohol products are made by refilling empty bottles used by the original manufacturer. This counterfeiting method does not require the production of new bottles, but can be recycled in the market, which is extremely cheap; secondly, because the bottles are all original products, consumers cannot distinguish their authenticity from the appearance alone.
[0003] In order to prevent illegal personnel from recycling wine bottles and counterfeiting, the manufacturer has launched a bottle cap lining made of composite materials. Specifically, a metal anti-pry ring is installed in the plastic lining of the bottle cap. It not only takes advantage of the advantages of plastic parts that are easy to form and easy to fit, but also makes up for the defects of metal parts that are not resistant to knife prying and fire. Once the metal anti-pry ring is installed on the bottle, it is difficult to remove it. Counterfeiters will encounter difficulties in this way by removing the bottle cap as a whole and then making a new bottle cap to match the original bottle.
[0004] As counterfeiting activities escalate, counterfeiters have discovered that they do not need to remove the entire bottle cap. Instead, they only need to destroy the plastic part of the bottle cap, leaving the metal anti-tamper ring on the neck of the bottle. They only need to remake the damaged plastic part, fill the original bottle with fake wine, and then put it on the outside of the metal anti-tamper ring to complete the seal. Compared with destroying the entire bottle cap and remaking a complete fake cap, this counterfeiting method uses the metal anti-tamper ring on the original bottle cap, making it cheaper. Consumers are also unable to distinguish from the appearance. Utility Model Content
[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a safer and more reliable metal anti-pry ring with a gear ring and a bottle cap using the same.
[0006] The technical solutions of the utility model are as follows:
[0007] A metal anti-pry ring with a gear ring comprises a ring body which passes through from top to bottom, an undercut pointing obliquely upward is arranged on the inner side of the ring body, a gear-shaped resistance ring is radially arranged on the upper end or the lower end of the ring body, and the outer diameter of the gear-shaped resistance ring is larger than the outer diameter of the ring body.
[0008] A bottle cap with a metal anti-pry ring with a gear ring includes an inner liner, a bottle mouth, an upper cover, and a lower cover. The inner liner is fixedly connected to the bottle mouth, the metal anti-pry ring is placed on the inner side of the inner liner and is fixedly connected to the inner liner; the upper cover is movably connected to the bottle mouth and is located on the outer side of the bottle mouth; the lower cover is fixedly connected to the inner liner.
[0009] Wherein, the protruding teeth of the gear-shaped resistance sleeve ring are embedded in the inner wall of the liner.
[0010] Wherein, an inner anti-rotation rib is provided on the inner side of the lining.
[0011] Wherein, an external anti-rotation rib is provided on the outer side of the inner lining.
[0012] Wherein, an outer lining buckle is provided on the outer side of the lining.

[0038] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0039] Embodiment 1:
[0040] like Figures 1 to 3 A metal anti-pry ring with a gear ring, comprising a ring body 11 that passes through from top to bottom, an undercut 12 pointing obliquely upward is arranged on the inner side of the ring body 11, a gear-shaped resistance ring 13 is radially arranged on the upper end of the ring body 11, and a plurality of convex teeth 14 are evenly distributed on the outer side of the resistance ring 13, and the outer diameter of the convex teeth 14 is larger than the outer diameter of the ring body 11.
[0041] The resistance ring 13 can be made separately (rather than being directly folded from the upper part of the ring body. The outer diameter and thickness of the separately made resistance ring only need to consider the anti-sleeving and anti-shear and anti-prying performance, and do not need to consider the stamping and stretching performance of the ring body as in the case of integral folding), and then riveted / clamped / welded to the ring body 11. The diameter and tooth spacing of the convex teeth 14 can adjust the anti-sleeving ability and the connection strength of the upper and lower parts of the liner 2. (Detailed description of Example 3)
[0042] Embodiment 2:
[0043] like Figure 4 , 5As shown. A metal anti-pry ring with a gear ring, including a ring body 11 that passes through from top to bottom, the inner side of the ring body 11 is provided with an undercut 12 pointing obliquely upward, the lower end of the ring body 11 is radially provided with a gear-shaped resistance ring 13, and the outer side of the resistance ring 13 is evenly distributed with a plurality of convex teeth 14, and the outer diameter of the convex teeth 14 is larger than the outer diameter of the ring body 11. The resistance ring 13 is formed by directly folding outward the lower part of the ring body 11. Compared with the separate production of Example 1, the advantage of directly folding outward is low cost, and the disadvantage is that the diameter and thickness of the resistance ring 13 must be selected taking into account the ring body 11. If the diameter is too large and the thickness is too thick, it will increase the difficulty of stamping and stretching the ring body 11, and the yield rate will decrease.
[0044] Embodiment three:
[0045] like Figures 6 to 10 As shown, a bottle cap with a metal anti-tamper ring with a gear ring includes an inner liner 2, a bottle mouth 3, an upper cover 4, and a lower cover 5.
[0046] The liner 2 and the bottle mouth 3 are integrally injection molded, and the metal anti-pry ring 1 is placed on the inner side of the liner 2. The metal anti-pry ring 1 is placed in the injection mold when the liner 2 and the bottle mouth 3 are integrally injection molded, so that the liner 2 covers the metal anti-pry ring 1, and the resistance ring 13 is embedded in the plastic of the liner wall.
[0047] For the sake of simplicity, this embodiment only takes the metal anti-pry ring in the second embodiment as an example, that is, the resistance ring 13 is located at the lower part of the ring body 11. The resistance ring 13 in the first embodiment is located at the upper part, and the principle is the same as that of the lower part, so it is not repeated.
[0048] The outer side of the bottle mouth 3 is provided with a bottle mouth thread 31 .
[0049] The inner side of the lining 2 is provided with an inner lining anti-rotation rib 21 .
[0050] The outer side of the lining 2 is provided with an inner lining outer anti-rotation rib 22 .
[0051] The outer side of the lining 2 is provided with an inner lining outer buckle 23 .
[0052] The upper cover 4 is provided with an upper cover thread 41 on the inner side thereof, and the upper cover thread 41 cooperates with the bottle mouth thread 31 to rotatably connect the upper cover 4 to the outer side of the bottle mouth 3 .
[0053] The lower part of the upper cover 4 is also provided with a notch 42 .
[0054] The inner side of the lower cover 5 is provided with a lower cover anti-rotation rib 52 and a lower cover buckle 51, and the upper part is provided with an anti-counterfeiting whisker 53.
[0055] The lining 2 screwed on the upper cover 4 is pressed down into the lower cover 5, so that the lower cover 5 is fixedly connected to the outer side of the lining 2. When pressing down, the notch 42 needs to be aligned with the anti-counterfeiting whiskers 53. After the pressing is completed, the anti-counterfeiting whiskers 53 are placed in the notch 42. The outer buckle 23 of the lining is buckled under the lower cover buckle 51, so that the lining 2 cannot be pulled up. The lower cover anti-rotation rib 52 cooperates with the outer anti-rotation rib 22 of the lining to prevent the two from rotating relative to each other.
[0056] The entire bottle cap is connected as one and pressed onto the bottle neck 6. The undercut 12 of the metal anti-pry ring 1 is buckled under the bottle neck locking hoop 61 to prevent the bottle cap from being pulled up. The anti-rotation ribs 21 in the liner and the anti-rotation ribs 62 in the bottle neck cooperate with each other to prevent the bottle cap from rotating, and the bottle is sealed.
[0057] When opening, the upper cover 4 is rotated, and the side wall of the notch 42 squeezes off the anti-counterfeiting whiskers 53, leaving an opening mark.
[0058] If a counterfeiter wants to remove the lower cover 5 with the damaged anti-counterfeiting whiskers 53 and re-make a counterfeit product and install the liner 2, the counterfeit lower cover 5 cannot be inserted from the bottom of the liner 2 because the liner 2 is hugged on the bottle neck 6. Then, if the counterfeiter wants to complete the assembly of the lower cover 4 and the liner 2, he can only destroy the plastic liner 2 together, re-make a counterfeit product, assemble the counterfeit lower cover 5, the counterfeit liner 2 (together with the bottle mouth 3), and the recycled upper cover 4, and then insert it into the metal anti-pry ring 1 on the bottle neck 6.
[0059] As can be seen from the above description, since the inner liner 2 is coated on the metal anti-pry ring 1, the inner diameter of the inner liner 2 is equal to the outer diameter of the metal anti-pry ring body 11, and the outer diameter of the resistance ring 13 is larger than the outer diameter of the ring body 11, after the inner liner 2 is assembled on the bottleneck 6, if the counterfeiter takes out the inner liner 2 by burning, prying with a knife, etc., and then makes a new inner liner 2, it will not be possible to put it on the outer side of the metal anti-pry ring 1 hugging the bottleneck 6. Because the outer diameter of the resistance ring 13 is larger than the inner diameter of the inner liner 2, the later made inner liner 2 cannot be inserted. Therefore, it can effectively prevent counterfeiters from counterfeiting by this method.
[0060] The gear-type structure of the resistance ring 13 can ensure the resistance sleeve while taking into account the upper and lower connection strength of the liner 2. If the resistance ring 13 is made into a circular ring simply to realize the function of the resistance sleeve, this function can also be realized, but the plastic wall thickness of the liner 2 at the horizontal plane of the resistance ring 13 is too small, and the risk of breaking here is relatively large. However, if a gear-type structure is adopted, the diameter of the convex teeth 14 is equal to the diameter of the circular ring, because the diameter of the resistance ring 13 at the concave notch 15 between the two convex teeth 14 is smaller, that is, the wall thickness of the liner 2 at the concave notch 15 is larger, which enhances the strength of the liner 2 at the horizontal plane of the resistance ring 13, making it difficult to break. The width of the concave notch 15 can be adjusted to adjust the strength of the liner 2. And the width of the convex teeth 14 can be adjusted to adjust the strength of the resistance ring 13. In actual production, the widths of the convex teeth 14 and the concave notch 15 can be adjusted accordingly as needed.
[0061] The resistance ring 13 can be directly folded out from the upper or lower end of the ring body 11 of the metal anti-pry ring, or it can be made separately and then fixedly connected to the ring body 11. The advantage of folding it out directly is that one less component is required, and the production cost is low. The disadvantage is that the thickness of the resistance ring 13 can only be the same as that of the ring body 11, which sacrifices the strength of the resistance ring 13 to a certain extent. The material cannot be too thick. If the material is too thick, it is difficult to shape the ring body 11, and it is also difficult for the inverted buckle 12 to slide over the bottleneck locking hoop 61 when the bottle cap is assembled with the bottle.
[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
