Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, and more specifically to an anti-pulling and anti-counterfeiting bottle cap. Background Art

[0002] At present, the counterfeiting of alcoholic products is rampant in the market. Counterfeiters make profits by canning non-original alcoholic beverages, which has a serious impact on alcoholic beverage brands. In order to protect their brands, alcoholic beverage manufacturers usually install anti-counterfeiting devices on bottle caps.

[0003] In the prior art, an anti-counterfeiting label or opening mark is often used on the bottle cap as an anti-counterfeiting mark, and the authenticity is identified by confirming the anti-counterfeiting label or opening mark;

[0004] However, this anti-counterfeiting method will not damage the bottle cap when the cap is forcibly removed, and the bottle cap can be reassembled and restored to the bottle body after removal, so it is impossible to prevent counterfeiters from removing the cap and canning fake wine.

For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0045] The utility model is described in detail below.

[0046] like Figure 1-Figure 10 As shown:

[0047] An anti-pullout and anti-counterfeiting bottle cap, used in conjunction with a bottle neck 6, comprises an outer cap 1, an inner cap 2 sleeved in an outer cap, a main body 3 sleeved in the inner cap 2 and screwed with the inner cap 2, an outer explosion ring 4 sleeved on the outside of the main body 3, and an inner plug 5 sleeved in the main body 3;

[0048] A clamping cavity 7 for mounting the outer explosion ring 4 is formed between the main body 3 and the outer cover 1 and located on one side of the inner cover 2 close to the inner plug 5;

[0049] The outer side surface of the outer explosion ring 4 is snap-fitted with the inner side surface of the outer cover 1 .

[0050] After assembly, the outer explosion ring 4 will be located in the clamping cavity 7, and the outer cover 1 will form a clamping fit; when opening or forcibly pulling out the cover, the outer cover 1 will drive the outer explosion ring 4 to move away from the bottle body, and the outer explosion ring 4 moves with the outer cover 1 and explodes from the platform edge 34 of the main body 3, and moves upward relative to the main body 3, and the outer cover 1, the inner cover 2 and the main body 3 will be separated; when the outer explosion ring 4 is opened normally or forcibly exploded, it will not be able to be assembled into the clamping cavity 7 again, so it cannot be restored, and an obvious trace is formed, thereby avoiding the situation of filling fake wine into the wine bottle and restoring it to its original state, which has a good anti-counterfeiting effect;

[0051] In some possible implementations, in order to effectively realize the snap fit between the outer explosion ring 4 and the outer cover 1, and to enable the outer explosion ring 4 to move away from the bottle body when the outer cover 1 moves away from the bottle body;

[0052] An inner fastener 13 is provided on the inner side of the outer cover 1 to engage with the outer explosion ring 4;

[0053] The outer explosive ring 4 includes a circular ring 41 located in the clamping cavity 7, and an outer clamping member 42 located outside the circular ring 41 and having its bottom abutted against the top surface of the inner clamping member 13; the top surface of the circular ring 41 abuts against the bottom surface of the inner cover 2; the outer clamping member 32 is annular and is sleeved on the outside of the circular ring 41, and the bottom of the outer clamping member 42 is coplanar with the bottom of the circular ring 41;

[0054] In some possible implementations, in order to effectively achieve the cooperation between the outer explosion ring 4 and the main body 3, and to make the outer explosion ring 4 unable to return to its original state after exploding from the clamping cavity 7;

[0055] A platform edge 34 is provided on the outer side of the main body 3 to cooperate with the outer explosion ring 4;

[0056] The outer explosion ring 4 also includes an outer explosion fastener 43 which is arranged at one end of the ring 41 away from the inner cover 2 and whose inner side surface cooperates with the platform edge 34;

[0057] When opened or pulled out, the outward-explosive fastener 43 will move from below the edge 34 to above the edge 34 .

[0058] After assembly, the bottom of the outer snap fastener 42 will be located above the inner snap fastener 13; when opening or forcibly pulling out the cover, the outer cover 1 will be controlled to move away from the bottle body, thereby driving the inner snap fastener 13 to move away from the bottle body, and making the top of the inner snap fastener 13 abut against the bottom of the outer snap fastener 42, so that the outer cover 1 continues to move, the inner snap fastener 13 will continue to move, and drive the outer snap fastener 42 to move away from the bottle body. During the whole moving process, the main body 3 will not move because it is connected to the bottleneck 6 to form a whole. Then, the outer snap fastener 43 moves away from the bottle body, and moves from the bottom of the platform edge 34 to the top of the platform edge 34, and slides out of the clamping cavity 7. After sliding out, the inner cover 2 will be separated from the main body 3;

[0059] Furthermore, the bottom surface of the platform edge 34 is inclined, and the angle formed with the outer side surface of the main body 3 is an acute angle, and the top surface of the platform edge 34 is a plane that acts as a limit surface to limit the downward movement of the external explosion fastener 34 during restoration;

[0060] The top surface of the external explosion fastener 43 is also inclined, so that the two can be effectively connected and separated; when separated, the external explosion fastener 43 will slide along the bottom surface of the platform 34 to the side away from the bottle body, so that the external explosion fastener 43 slides out from the gap formed between the inner side of the outer cover 1 and the platform 34, and the external explosion fastener 43 cannot be restored to its original state under the action of external force after sliding out of the gap, so that an obvious mark will be generated between the outer cover 1 and the bottleneck 6, achieving the purpose of anti-counterfeiting;

[0061] In some possible implementations, in order to avoid processing and manufacturing, the assembly of the outer explosion ring 4, the main body 3, and the outer cover 1 is made simpler and more convenient;

[0062] The inner fasteners 13 are in three groups, which can be engaged with the outer fasteners 42 of a whole circle. The three groups of inner fasteners 13 are evenly arranged along the circumference of the ring 41 and on the same plane.

[0063] Furthermore, there are three groups of external explosion fasteners 43, which are evenly arranged along the circumference of the ring 41, and an open groove with an opening facing downward is formed between two adjacent groups of external explosion fasteners 43; the internal fastener 13 will be located in the open groove.

[0064] In some possible implementations, in order to effectively realize the connection between the outer cover 1 and the inner cover 2, the outer cover 1 is prevented from rotating around the inner cover 2;

[0065] A plurality of first buckles 12 are arranged on the inner side of the outer cover 1 along its circumference; a first clamping groove 22 used with the first buckle 12 is arranged on the outer side of the inner cover 2; the first buckle 12 is located above the inner buckle 13;

Anti-rotation grooves 21 used in conjunction with the anti-rotation strips 11 are provided on the outer side surface of the inner cover 2. The anti-rotation strips 11 are located above the first buckle 12.

[0067] The cooperation between the anti-rotation strip 11 and the anti-rotation groove 21 provided in the outer cover 1 will effectively prevent the outer cover 1 from rotating around the axis of the inner cover 2, so that the inner cover 2 can be driven to rotate around its axis by twisting the outer cover 1, thereby separating the inner cover 2 from the main body 3;

[0068] The cooperation between the first buckle 12 and the first slot 22 can effectively prevent the outer cover 1 from being separated from the inner cover 2;

[0069] Specifically, the first buckle 12 is arranged along the circumference of the outer cover 1, and the first clamping groove 22 is an annular structure.

[0070] In some possible implementations, in order to effectively fit the main body 3 into the inner cover 2 and to effectively separate the inner cover 2 from the main body 3;

[0071] A first sealing cylindrical surface 23 coaxially arranged with the inner cover 2 is arranged at the top of the inner cover 2 , and an annular chamber 24 is formed between the first sealing cylindrical surface 23 and the inner side surface of the inner cover 2 .

[0077] In some possible implementations, in order to effectively achieve the connection between the main body 3 and the bottleneck 6;

[0078] An anti-pullout buckle 35 that engages with the bottleneck 6 and a rotation-stopping convex strip 36 that is arranged axially along the length direction of the main body and cooperates with the bottleneck 6 are also provided on the inner side surface of the main body; the anti-pullout buckle 35 is located in a cavity formed by the outer side surface of the outer sealing cylinder 32 and the inner side surface of the main body, and the anti-pullout buckle 35 is in multiple groups and is evenly arranged along the circumference of the main body.

[0079] In some possible implementations, an anti-extraction boss 61 used in conjunction with the anti-extraction buckle 35 and an anti-rotation groove 62 used in conjunction with the anti-rotation convex strip 36 are provided on the outer side of the bottleneck 6;

[0080] The anti-pulling boss 61 is arranged on the outer side of the bottleneck 6 close to the inner plug 5 and forms a slot with the outer side of the bottleneck 6. The anti-pulling buckle 35 will be located in the slot, so that the two will not be separated;

[0081] The long direction of the anti-rotation convex strips 36 is arranged along the axial direction of the body. The anti-rotation convex strips 36 are arranged in multiple groups and correspond to the anti-rotation grooves 62 one by one, so as to effectively prevent the body 3 and the bottleneck 6 from rotating.

[0082] In some possible implementations, in order to effectively fix the inner plug 5;

[0083] The inner plug 5 includes a wine outlet section 51 which is sleeved in the bottle neck 6 , and a flange portion 52 which is arranged between the top of the bottle neck 6 and the wine outlet section 31 and connected to the wine outlet section 51 .

[0084] The wine outlet section 51 is coaxial with and connected to the wine outlet nozzle section 31 ; the wine outlet section 51 is sleeved in the bottleneck 6 , and the flange portion 52 is connected to the top of the wine outlet section 51 and is located at the top of the bottleneck 6 .

[0085] During assembly, the inner plug 5 is assembled upward from the lower end of the main body 3, guided by the outer sealing cylindrical surface 32;

[0086] The outer cover 1 is assembled from the inner cover 2 from top to bottom, the anti-rotation strip 11 is matched with the anti-rotation groove 21 , and the first buckle 12 is clamped in the first clamping groove 22 .
