Description

Technical Field

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

[0002] 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;

[0003] However, this anti-counterfeiting method will not damage the bottle cap when the cap is forcibly removed, and the bottle cap can be reassembled on the bottle body after removal, so it is impossible to prevent counterfeiters from removing the cap and canning fake wine. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an anti-counterfeiting bottle cap with an anti-pulling function;

[0005] The solution adopted by the utility model to solve the technical problem is:

[0006] An anti-counterfeiting bottle cap with an anti-pulling function, used in conjunction with a bottleneck, comprises an outer cap, an inner cap sleeved in the outer cap and clamped with the outer cap, a lower tube located below the outer cap and clamped with the outer cap and the inner cap respectively, a main body sleeved in the lower tube and one end of which passes through the lower tube and is connected to the inner cap, and an inner plug sleeved in the bottleneck and one end of which passes through the bottleneck and sleeved in the main body; the main body sleeved on the outside of the bottleneck; an anti-counterfeiting seal member clamped with the top of the outer cap is arranged on the inner cap;

[0007] A slot is formed between the end of the lower tube close to the outer cover and the main body to cooperate with the bottom of the inner cover. When opening normally, the outer cover is rotated around its axis, and the outer cover drives the inner cover to rotate away from the bottleneck, and the bottom of the inner cover slides out of the slot to open the bottle.

[0008] When counterfeiting, a pulling method is usually used to avoid damage to the bottle cap. Since the anti-counterfeiting seal on the inner cap is engaged with the top of the outer cap, when the outer cap is subjected to a force acting toward the side away from the bottleneck, the anti-counterfeiting seal is driven to move toward the side away from the bottleneck, thereby separating and breaking the anti-counterfeiting seal from the inner cap; the above-mentioned broken part cannot be restored, thereby achieving anti-counterfeiting and having a good anti-pulling effect;

[0009] In some possible implementations, in order to effectively achieve the connection between the outer cover and the lower tube;

[0010] An opening groove opening upward is arranged at one end of the lower tube close to the outer cover, and an arc-shaped pull-off blocking strip is arranged in the opening groove;

[0011] An opening tooth is arranged in an arc shape on one side of the outer cover close to the lower tube and is engaged with the break strip. Since the opening tooth of the outer cover and the break strip of the lower tube are engaged, when the outer cover is subjected to a force, the opening tooth breaks the break strip of the lower tube, thereby achieving anti-counterfeiting and having a good anti-pullout effect.

[0012] During normal opening, the outer cover rotates, driving the opening teeth to rotate, and the opening teeth are squeezed by the inner side of the lower tube, thereby breaking off from the outer cover, thereby separating the outer cover from the lower tube;

[0013] When the outer cover is subjected to a pulling force away from the bottleneck, the opening teeth will also be forced to move, thereby driving the breaking bar located in the opening groove to move away from the bottleneck. Since both ends of the breaking bar are connected to the inner side of the opening groove, both ends of the breaking bar will be broken.

[0014] In some possible implementations, in order to effectively implement the installation of the anti-counterfeiting seal;

[0015] The inner cover comprises a body; the anti-counterfeiting seal is arranged on a side of the body away from the main body and is snap-fitted with the outer cover; and one end of the body close to the inner cover is sleeved in the body.

[0016] In some possible implementations, in order to effectively make the body engage with the outer cover and the lower tube respectively;

[0017] A mounting hole for mounting an anti-counterfeiting seal and communicating with the interior of the body is arranged on the top of the body, and an implosion disk matched with the card slot is arranged on the bottom of the body.

[0018] In some possible implementations, in order to enable the anti-counterfeiting seal to effectively achieve sealing, and to separate and break from the body under the action of a pulling force;

[0019] The anti-counterfeiting seal includes an annular buckle which is coaxially arranged with the mounting hole and has an annular structure, and a tear surface which is arranged in the mounting hole and connected to the inner side surface of the mounting hole; the annular buckle is installed on the tear surface, and a clamping portion which cooperates with the annular buckle is arranged on the inner side surface of the top of the outer cover.

[0020] In some possible implementations,

[0021] An annular clamping strip is arranged outside the body and above the inner implosion disk, a clamping groove is formed between the annular clamping strip and the inner implosion disk, and a buckle member is arranged inside the outer cover and cooperates with the clamping groove and is located above the inner implosion disk.

[0022] In some possible implementations,

[0023] The anti-counterfeiting seal also includes a sealing guide portion which is installed on the inner side of the body and has a tubular structure and is coaxial with the mounting hole. The inner side of the sealing guide portion is coplanar with the inner side surface of the mounting hole, and an annular groove is formed between the outer side surface of the sealing guide portion and the inner side surface of the body.

[0024] In some possible implementations,

[0025] A transparent anti-counterfeiting gasket is also arranged in the installation hole and at the bottom of the main body.

[0026] In some possible implementations,

[0027] A plurality of groups of anti-rotation convex strips are arranged on the inner side surface of the lower tube and along the circumference thereof, and an anti-rotation groove used in conjunction with the anti-rotation convex strips is arranged on the outer side of the main body; each group of anti-rotation convex strips is arranged parallel to the axial direction of the lower tube;

[0028] A limiting buckle is arranged at one end of the lower tube away from the outer cover and is used in conjunction with one end of the main body away from the outer cover.

[0029] In some possible implementations,

[0030] A plurality of groups of anti-pulling buckles are arranged on the inner side surface of the main body and in the circumferential direction thereof, and an anti-pulling boss used in conjunction with the anti-pulling buckles is arranged on the outer side of the bottleneck;

[0031] A rotation-stopping strip is arranged on the inner side surface of the main body and below the anti-pulling buckle, and a rotation-stopping groove used in conjunction with the rotation-stopping strip is arranged on the outer side of the bottleneck.

[0032] Compared with the prior art, the utility model has the following beneficial effects:

[0033] The utility model provides the cooperation between the clamping part and the anti-counterfeiting seal, the opening teeth and the breaking strip, so that when a pulling force is applied to the outer cover, the anti-counterfeiting seal and the breaking strip will both break; the anti-counterfeiting seal and the breaking strip cannot be restored after separation; the anti-pullout is achieved, and the bottle cap and the bottleneck are prevented from being separated by pulling to inject fake wine into the bottle;

[0034] The utility model has a simple structure and strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0046] The utility model is described in detail below.

[0047] like Figure 1-Figure 9 As shown:

[0048] An anti-counterfeiting bottle cap with an anti-pulling function, used in conjunction with a bottleneck 6, comprises an outer cap 1, an inner cap 3 sleeved in the outer cap 1 and clamped with the outer cap 1, a lower tube 2 located below the outer cap 1 and clamped with the outer cap 1 and the inner cap 3, a main body 4 sleeved in the lower tube 2 and one end of which passes through the lower tube 2 and is connected to the inner cap 3, and an inner plug 5 sleeved in the bottleneck 6 and one end of which passes through the bottleneck 6 and sleeved in the main body 4; the main body 4 is sleeved on the outside of the bottleneck 6; an anti-counterfeiting seal 31 clamped with the top of the outer cap 1 is provided on the inner cap 3;

[0049] In the utility model, the bottleneck 6, the outer cover 1, the inner cover 3, the lower tube 2, the main body 4, and the inner plug 5 are all coaxially arranged;

[0050] A slot for cooperating with the bottom of the inner cover 3 is formed between the end of the lower tube 2 close to the outer cover 1 and the main body 4 .

[0051] During normal opening, the outer cover 1 is rotated around the axis direction of the outer cover 1, and the outer cover 1 drives the inner cover 3 to rotate away from the bottleneck 6, the outer cover 1 is separated from the lower tube 2, and the bottom of the inner cover 3 slides out of the slot to achieve opening;

[0052] When counterfeiting, a pulling method is usually used to avoid damage to the bottle cap. Since the anti-counterfeiting seal 31 on the inner cap 3 is engaged with the top of the outer cap 1, when the outer cap 1 is subjected to a force acting toward the side away from the bottleneck 6, the anti-counterfeiting seal 31 is driven to move toward the side away from the bottleneck 6, so that the anti-counterfeiting seal 31 is separated and broken from the inner cap 3, and the broken part cannot be restored, thereby achieving anti-counterfeiting and having a good anti-pulling effect;

[0053] In some possible implementations, in order to effectively achieve the connection between the outer cover 1 and the lower tube 2;

[0054] An opening groove 21 opening upward is provided at one end of the lower tube 2 close to the outer cover 1, and an arc-shaped break bar 22 is provided in the opening groove 21; an opening tooth 11 engaging with the break bar 22 is provided on one side of the outer cover 1 close to the lower tube 2;

[0055] The two ends of the break strip 22 are connected to the inner side of the opening groove 21, and the bottom thereof forms a gap with the bottom of the opening groove 21; the break strip 22 is in an arc shape and its center is on the axis of the long direction of the lower tube 2.

[0056] The opening teeth 11 include a connecting plate, a connecting point disposed between the connecting plate and the bottom of the outer cover 1, and a clamping plate disposed on a side of the connecting plate away from the connecting point and cooperating with the connecting plate to form a hook-shaped structure;

[0057] When the cover is forcibly pulled out, the clamping plate will be located in the gap and abut against the bottom of the pull-off stop bar 22;

[0058] During normal opening, the outer cover 1 rotates, driving the opening teeth 11 to rotate, and the opening teeth 11 are squeezed by the inner side of the lower tube 2, so that the outer cover 1 is broken at the connection point, thereby separating the outer cover 1 from the lower tube 2;

[0059] When the outer cover 1 is subjected to a pulling force away from the bottleneck 6, the opening teeth 11 will also be subjected to the force to move, thereby driving the break-off stop bar 22 located in the opening groove 21 to move away from the bottleneck 6. Since both ends of the break-off stop bar 22 are connected to the inner side of the opening groove 21, the break-off stop bar 22 will be broken. At the same time, since the opening teeth 11 of the outer cover 1 and the break-off stop bar 22 of the lower tube 2 are in a snap-fitting fit, after the outer cover 1 is subjected to the force, the opening teeth 11 break the break-off stop bar 22 of the lower tube 2.

[0060] In some possible implementations, in order to effectively implement the installation of the anti-counterfeiting seal 31;

[0061] The anti-counterfeiting seal 31 is arranged on the side of the main body away from the main body 4 and is engaged with the outer cover 1; the end of the main body 4 close to the inner cover 3 is sleeved in the main body.

The annular buckle 311 is arranged on the top surface of the tear surface 312 and the clamping part 12 is engaged and matched. When the cover is forcibly pulled out, the annular buckle 311 and the tear surface 312 will be driven to move away from the bottleneck 6, thereby causing the tear surface 312 to separate and break from the body.

[0069] After assembly, the latch 13 is arranged in the latching groove 34. After the breaking stop bar 22 is broken, the outer cover 1 moves away from the bottleneck 6 as the outer cover 1 is pulled, and abuts against the annular clamping strip 33, so that the outer cover 1 drives the inner cover 3 to move away from the bottleneck 6, and the inner cover 3 is pulled out. After the inner cover 3 is pulled out, the inner explosion disk 32 will no longer be located in the latching groove. Due to the breaking of the breaking stop bar 22, the separation of the anti-counterfeiting seal 31 and the body, and the explosion of the inner explosion disk 32, the entire bottle cap cannot be restored again, and the anti-counterfeiting is effectively achieved.

[0070] Furthermore, a platform edge is provided at one end of the lower tube 2 close to the outer cover 1. After assembly, the platform edge will be located in the clamping groove 34 and below the clamping member 13, and the bottom of the platform edge will abut against the top surface of the inner implosion disk 32;

[0083] Specifically, the main body 4 includes a mounting section, a wine outlet section connected to the mounting section and located in the inner cover 3, a wine blocking portion provided in the wine outlet section and cooperating with the wine outlet section to form a wine outlet channel, and a connecting rib for connecting the wine blocking portion and the wine outlet section; the outer diameter of the mounting section is larger than the outer side of the wine outlet section;

[0084] The outer side of the wine outlet section is provided with an external thread, and the inner cover 3 is provided with an internal thread used in conjunction with the external thread;

[0085] The anti-pulling buckle 42 is arranged in the mounting section; the top of the bottleneck 6 will extend into the mounting section and realize the snap-fitting with the mounting section through the anti-pulling boss 61, and the anti-rotation strip 43 arranged in the mounting section will cooperate with the anti-rotation groove to effectively prevent the bottleneck 6 and the mounting section from rotating;

[0086] The inner plug 5 comprises a lower sealing ring sleeved in the bottle neck 6, a flange portion connected to the end of the lower sealing ring away from the bottle neck 6 and conveniently facing outward, and an upper sealing cylinder arranged above the flange portion; the upper sealing cylinder will extend into the wine spout section during assembly; the base of the flange portion will act on the top of the bottle neck 6;

[0087] When assembling the bottle cap and the bottleneck 6:

[0088] The inner plug 5 is assembled upward from the lower end of the main body 4, and is installed into the lower sealing cylinder provided on the wine spout section with the upper sealing cylinder as a guide.
