[0022] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be combined arbitrarily to form new embodiments.

[0023] Embodiment:

[0024] Please refer to Figures 1-5 , a twist-off anti-counterfeiting bottle cap of this embodiment includes a neck sleeve 3. A circle of abutting parts 31 is arranged on the outer circle of the neck sleeve 3. Three groups of equally spaced first connecting strips 32 are arranged on the abutting parts 31. The upper half of the outer circle of the neck sleeve 3 is sleeved with an upper cover 2, and the bottom end of the upper cover 2 is in contact with the abutting part 31. A docking notch 22 is opened at the bottom end of the outer circle of the upper cover 2. A plurality of first connecting strips 32 are placed in the docking notch 22 and are welded between them. The top cover 1 is installed on the top of the upper cover 2;

[0025] The bottle mouth 5 is sleeved inside the neck sleeve 3. The upper half of the bottle mouth 5 is placed above the neck sleeve 3. An inner plug 6 is arranged inside the bottle mouth 5. A white cap 4 is screwed on the upper part of the bottle mouth 5, and the white cap 4 extends into the upper cover 2.

[0026] A boss structure is arranged on the outer ring surface of the bottle mouth 5. A plurality of connecting strips II 51 are arranged on the boss structure at equal intervals. A plurality of connecting ribs are arranged in a circular distribution on the inner ring of the neck sleeve 3, and the connecting ribs are clamped into the gaps formed by adjacent connecting strips II 51.

[0027] A spiral part 53 is arranged on the lower half of the inner ring of the bottle mouth 5. There is a gap between the outer ring of the inner plug 6 and the inner ring of the bottle mouth 5. This gap is used to install the bottle mouth of the white wine bottle, and a spiral line matching the spiral part 53 is arranged on the bottle mouth. The bottle mouth 5 and the bottle mouth of the white wine bottle are screwed and connected through the spiral part 53, and there is a good connection effect between the two.

[0028] An annular groove 52 is arranged below the outer ring surface of the bottle mouth 5. A plurality of elastic protrusions 34 are arranged in a circular distribution on the inner ring surface of the neck sleeve 3. The elastic protrusions 34 slide in the annular groove 52. After the neck sleeve 3 is sleeved above the bottle mouth 5, the elastic protrusions 34 can be placed in the annular groove 52, so that the neck sleeve 3 and the bottle mouth 5 are connected together. At this time, the neck sleeve 3 cannot be pulled upward to break away from the bottle mouth 5.

[0029] The thickness of the connecting strip II 51 is not less than the thickness of the connecting strip I 32, that is, the strength of the connecting strip II 51 is not less than the strength of the connecting strip I 32. So when the upper cover 2 is being screwed, after the connecting strip I 32 is broken, the connecting strip II 51 has not been completely broken or broken along with it. In this way, when the neck sleeve 3 is screwed, the connecting strip II 51 can be broken.

[0030] A plurality of positioning columns 33 are arranged in a circular distribution on the top surface of the neck sleeve 3. A plurality of positioning grooves are arranged in a circular distribution at the bottom of the upper cover 2. The positioning columns 33 are inserted into the positioning grooves, and the two are in interference fit, which can quickly connect the neck sleeve 3 and the upper cover 2, so as to facilitate subsequent welding of the two and it is not easy to fall off.

[0031] A connecting part 11 is arranged at the lower end of the top cover 1. A connecting notch 12 is arranged on the inner side of the connecting part 11 facing inwards. A connecting clamping plate 21 is arranged at the top end inside the upper cover 2. The connecting part 11 is clamped inside the upper cover 2, and the connecting clamping plate 21 is clamped into the connecting notch 12. When the top cover 1 is pressed on the upper cover 2 from top to bottom, its connecting part 11 will deform during the downward movement, and the connecting notch 12 will be aligned with the connecting clamping plate 21, thus completing the fixation of the two and improving the connection strength.

[0032] In the embodiment of the present application, the implementation principle of a twist-off anti-counterfeiting bottle cap is as follows: during actual use, first fix the inner plug 6 inside the bottle mouth 5, and screw on the white cap 4 above the bottle mouth 5. Then, screw the bottle mouth 5 onto the bottle neck through the spiral part 53. The upper cap 2 is sleeved above the neck sleeve 3, and the bottom end of the upper cap 2 contacts the abutting part 31. At this time, the positioning post 33 will be inserted into the positioning groove, and multiple first connecting strips 32 will also be placed in the docking notch 22. Then, weld the first connecting strip 32 to the top of the docking notch 22. After that, sleeve the neck sleeve 3 onto the bottle mouth 5, and place the white cap 4 inside the upper cap 2. At this time, after the neck sleeve 3 is sleeved above the bottle mouth 5, the elastic protrusion 34 can be placed in the annular groove 52, so that the neck sleeve 3 and the bottle mouth 5 are connected together. At this time, the neck sleeve 3 cannot be pulled upwards to detach from the bottle mouth 5, and the connecting ribs inside the neck sleeve 3 will also be inserted into the spacing formed by the adjacent second connecting strips 51;

[0033] When opening the bottle cap, it is necessary to twist the upper cap 2. At this time, the first connecting strip 32 between the upper cap 2 and the neck sleeve 3 will break, and the feature at this time is more obvious, so the authenticity can be judged;

[0034] If you want to disassemble the neck sleeve 3, you need to disassemble it together with the bottle mouth 5. At this time, you need to rotate the bottle mouth 5, and rotating the bottle mouth 5 requires removing the upper cap 2 above first. In this way, there will be a break point, which can be used to distinguish the authenticity. If you directly rotate the neck sleeve 3 without removing the upper cap 2, the rotating neck sleeve 3 will cause the second connecting strip 51 to break, and it cannot be completely removed, so that the entire bottle cap cannot be completely removed;

[0035] By providing an elastic protrusion 34 on the inner wall of the neck sleeve 3 and an annular groove 52 on the outer ring of the bottle mouth 5, after the neck sleeve 3 is installed above the bottle mouth 5, the elastic protrusion 34 can be placed in the annular groove 52. At this time, they cannot move up and down, only rotate. With the cooperation of the second connecting strip 51 and the connecting ribs provided, the neck sleeve 3 can damage the second connecting strip 51 when rotating, so that the bottle cap cannot be completely removed, improving the anti-counterfeiting effect;

[0036] The neck sleeve 3 and the upper cap 2 are connected by the first connecting strip 32, and the first connecting strip 32 is placed in the docking notch 22, making the whole first connecting strip 32 clearer. When opening, the whole first connecting strip 32 will be damaged, so it is convenient to see whether it has been opened, improving the anti-counterfeiting effect.

[0037] The above-mentioned implementation manner is only the preferred implementation manner of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
