Description

Technical Field

[0001] The present invention relates to the technical field of packaging components, and specifically relates to an anti-counterfeiting bottle cap. Background Art

[0002] At present, in the field of anti-counterfeiting packaging, anti-counterfeiting bottle caps have been widely used. In terms of the anti-counterfeiting of bottle caps, the commonly used means at present is destructive anti-counterfeiting, that is, the bottle cap is partially or completely damaged after being opened to prevent the bottle cap from being recycled, so as to achieve the purpose of anti-counterfeiting. In the structure of the anti-counterfeiting bottle cap, the existing outer cap and outer cap seat are usually provided with threaded ribs for engaging connection. The connection structure of such an outer cap and outer cap seat is single, that is, when the threaded ribs are not processed in place, it often causes the outer cap and the outer cap seat to be unable to be adaptively connected.

[0005] The above anti-counterfeiting bottle cap ensures the connection stability between the outer cover and the outer cover seat through the first-stage connection structure and the second-stage connection structure, but lacks a breakable anti-counterfeiting breaking part. For an anti-counterfeiting bottle cap, adding a breakable anti-counterfeiting breaking part to the bottle cap is a common setting method in the art. However, the existing breakable anti-counterfeiting structures operate independently and cannot be interlocked with other structures, resulting in poor anti-counterfeiting effects of the breakable anti-counterfeiting structures. Summary of the Invention

[0006] The present invention provides an anti-counterfeiting bottle cap, aiming to solve the problem that the breakable anti-counterfeiting structures of the existing anti-counterfeiting bottle caps operate independently, resulting in poor anti-counterfeiting effects.

[0007] The technical solution adopted by the present invention to solve its technical problems is: an anti-counterfeit bottle cap comprises a bottle mouth and an inner cover, a first flow channel is arranged in the bottle mouth, an external thread is arranged on the bottle mouth, an internal thread matching the external thread is arranged on the inner cover, a hook is fixedly arranged on the outer periphery of the bottle mouth, a slot matching the hook is arranged on the inner wall of the inner cover, a locking cover is arranged on the upper cover of the inner cover, the locking cover is clamped on the inner cover, the locking cover is rotatable relative to the inner cover, and the rotation axis is vertical; a tooth-breaking key is fixedly arranged on the top of the inner cover, a through hole is arranged on the top of the locking cover, a breaking piece is connected to the inner side of the through hole through a breakable tooth, the tooth-breaking key is used to distinguish the broken tooth, an installation groove is formed between the breaking piece and the through hole, a braking groove is arranged on the side wall of the inner cover, a braking piece is fixedly arranged on the groove wall of the braking groove, the braking piece is a self-resetting structure, the slot is arranged on the inner side wall of the braking piece, an annular skirt is fixedly arranged on the bottom of the locking cover, and a yielding cut is arranged on the skirt;

[0008] When the inner cover is installed on the bottle mouth, the internal thread is threadably connected with the external thread, and the hook is embedded in the slot; the upper part of the inner cover is embedded in the locking cover, and the tooth-breaking key is arranged in the installation slot, and at the same time, the skirt squeezes the brake part, and the brake part abuts against the outer wall of the bottle mouth, so that the inner cover is locked and fixed on the bottle mouth; after the locking cover is rotated until the tooth-breaking key breaks the broken teeth, it continues to rotate to align the clearance cut with the brake part, so that the brake part moves (i.e., tilts outward), and the hook is disengaged from the slot through the movement of the brake part.

[0009] Furthermore, a brake boss is fixed on the outer side of the brake member. After the clearance cutout is aligned with the brake member, the locking cover is rotated to make the side wall of the clearance cutout abut against the brake boss, so that the brake member is tilted outward and the hook is separated from the slot.

[0010] Furthermore, the brake member is a block extending obliquely from the inner cover to the outside, and the extension distance of the brake member does not exceed the brake groove. After the brake member is aligned with the clearance cut, the brake member resets itself to an outwardly tilted state, and the hook disengages from the groove.

[0011] Furthermore, the upper end surface of the locking cover, the upper end surface of the destroying member, and the upper end surface of the broken tooth key are located on the same horizontal plane and are bonded with labels.

[0012] In order to solve the problem of how to better clip and fix the bottle mouth on the container, a hook cut is opened on the lower side of the external thread of the bottle mouth, and an inward "7"-shaped hook is fixed on the lower side of the hook cut, and the lateral part of the "7"-shaped hook faces the outside of the bottle mouth. The bottle mouth is clipped and fixed to the assembly container by the "7"-shaped hook.

[0013] Furthermore, a lower tube is provided on the bottle mouth, the lower part of the bottle mouth is sleeved inside the lower tube, and the lower tube is clamped and fixed on the bottle mouth; when the bottle mouth is installed on the assembly container, the inner side wall of the "7"-shaped hook abuts against the assembly container, and the inner side wall of the lower tube limits the "7"-shaped hook from deforming outward, so that the "7"-shaped hook cannot be separated from the bottle mouth.

[0014] To solve the problem of the lower side fixation of the inner cap, a lower tube is sleeved on the bottle mouth. The lower part of the bottle mouth is sleeved inside the lower tube. The lower tube is snap - connected and fixed to the bottle mouth. An annular rib is fixedly provided inward at the top of the lower tube. A boss of the inner cap is fixedly provided at the bottom of the outer periphery of the inner cap. The outer diameter of the boss of the inner cap is smaller than the inner diameter of the annular rib. When the lower tube is installed on the bottle mouth, the lower end surface of the annular rib of the lower tube abuts and cooperates with the upper end surface of the boss of the inner cap.

[0015] Furthermore, a third snap - ring and a fourth snap - ring are provided at the bottom of the outer periphery of the bottle mouth. The fourth snap - ring is located below the third snap - ring. A lower - tube catch is provided on the inner side wall of the lower tube. Both the third snap - ring and the fourth snap - ring can be used for snap - connection with the lower - tube catch. The third snap - ring is used for snap - connecting the lower - tube catch before the bottle mouth is installed and fixed in the assembly container. The fourth snap - ring is used for snap - connecting the lower - tube catch after the bottle mouth is installed and fixed in the assembly container.

[0016] Furthermore, a plug is snap - connected and fixed inside the bottle mouth. A second flow channel is provided inside the plug. The second flow channel is communicated with the first flow channel. A flow - channel pipe is provided inside the second flow channel. The axis of the flow - channel pipe is vertically arranged. The periphery of the flow - channel pipe is fixedly connected with the plug.

[0017] To solve the problem that the flow - channel pipe has the effect of circulation while being fixed: the plug fixes and connects the flow - channel pipe through connecting pieces. There are multiple connecting pieces, and there are intervals between the connecting pieces.

[0018] Furthermore, the connecting pieces are annularly distributed around the flow - channel pipe.

[0019] To solve the problem of protecting the label sticker, an outer cap is further included. The outer cap is sleeved outside the locking cap. The outer cap is snap - connected and fixed to the locking cap. A conical tooth is provided on the upper side of the outer periphery of the locking cap. An anti - rotation tooth meshing with the conical tooth is provided inside the outer cap.

[0020] Furthermore, an outer - cap catch is provided on the lower side of the anti - rotation tooth of the outer cap. A first snap - ring and a second snap - ring are successively provided on the lower side of the conical tooth of the locking cap. Both the first snap - ring and the second snap - ring can be used for snap - connection with the outer - cap catch. The first snap - ring is used for snap - connecting the outer cap before the bottle mouth is installed and fixed in the assembly container. The second snap - ring is used for snap - connecting the outer cap after the bottle mouth is installed and fixed in the assembly container.

[0021] The beneficial effects of the present invention are as follows: The anti - counterfeiting bottle cap installs the broken - tooth key through the installation groove of the locking cap. At the same time, the skirt of the locking cap squeezes the brake of the inner cap inward, so that the inner cap is fixed on the bottle mouth. When opening, the broken tooth has been damaged by the broken - tooth key before the relief notch of the skirt aligns with the brake, realizing the linkage between the destructive part and the brake from the structure, and greatly improving the anti - counterfeiting effect.

[0022] In addition, the "7"-shaped catch provided on the bottle mouth is snap-connected and fixed to the container. The horizontal part of the "7"-shaped catch reduces the space for the outward displacement of the "7"-shaped catch and increases the required displacement distance, making it more difficult for the "7"-shaped catch to break away from the container, thereby improving the installation stability of the bottle mouth on the container. At the same time, the inner plug provided inside the bottle mouth divides the connection between the second channel and the flow channel pipe into several outlets through the connecting piece of the flow pipe provided in the center and the connecting flow channel pipe, so that when pouring fluid substances, there are sufficient air exchange channels, and the distribution of the flow channel and the air channel is more reasonable, improving the smoothness of pouring.

[0023] Among them, the lower pipe can be snap-connected to the two snap rings of the bottle mouth. Through the two snap rings at different positions, they respectively correspond to the two different states before and after the bottle mouth is installed and fixed on the assembly container. Similarly, the outer cover can be snap-connected to the snap rings distributed up and down of the locking cover, respectively corresponding to the two different states before and after the bottle mouth is installed and fixed on the assembly container. Through this setting method, all the structures before the container can be installed at one time, which is more concise than the existing structure that requires multiple installation processes, reduces costs while improving the stability of the structural cooperation. In addition, when installing, the user can simply and directly judge whether the installation is in place by whether the positions of the lower pipe and the outer cover are changed, and the installation is convenient and simple.

Detailed implementation manner

[0046] The present invention will be further described below with reference to the accompanying drawings.

[0047] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0048] Combined with Figure 1 、 Figure 2 、 Figure 3 、 Figure 13As shown in the figure, the anti-counterfeiting bottle cap of the present invention includes a bottle mouth 3 and an inner cap 4. A first flow channel 36 is provided in the bottle mouth 3. An external thread is provided on the bottle mouth 3. The inner cap 4 is provided with an internal thread that matches the external thread. A hook 33 is fixedly provided on the outer periphery of the bottle mouth 3. A slot 41 adapted to the hook 33 is formed in the inner wall of the inner cap 4. A locking cap 6 is covered on the inner cap 4. The locking cap 6 is snap-fitted on the inner cap 4. The locking cap 6 is rotatable relative to the inner cap 4, and the rotation axis is vertical. A broken tooth key 44 is fixedly provided at the top of the inner cap 4. A through hole 61 is formed in the top of the locking cap 6. A breaking member 612 is connected to the inner side of the through hole 61 through a breakable broken tooth 611. The broken tooth key 44 is used to break the broken tooth 611. An installation groove is formed between the breaking member 612 and the through hole 61. A braking groove is formed in the side wall of the inner cap 4. A braking member 43 is fixedly provided on the groove wall of the braking groove. The braking member 43 is a self-resetting structure. A circular skirt 62 is fixedly provided at the bottom of the locking cap 6. A relief notch 63 is formed in the skirt 62. When the inner cap 4 is installed on the bottle mouth 3, the internal thread is threadedly connected to the external thread, and the hook 33 is embedded in the slot 41. The upper part of the inner cap 4 is embedded in the locking cap 6. The broken tooth key 44 is arranged in the installation groove. At the same time, the skirt 62 presses the braking member 43, and the braking member 43 abuts against the outer side wall of the bottle mouth 3, so that the inner cap 4 is locked and fixed on the bottle mouth 3. After the locking cap 6 is rotated until the broken tooth key 44 breaks the broken tooth 611, it can be rotated further to align the relief notch 63 with the braking member 43, and then the braking member 43 resets, and the inner side wall of the braking member 43 is separated from the outer side wall of the bottle mouth 3. The anti-counterfeiting bottle cap installs the broken tooth key 44 through the installation groove of the locking cap 6. At the same time, the skirt 62 of the locking cap 6 presses the braking member 43 of the inner cap 4 inward, so that the inner cap 4 is fixed on the bottle mouth 3. When opening, the broken tooth 611 has been damaged by the broken tooth key 44 before the relief notch 63 of the skirt 62 is aligned with the braking member 43, realizing the linkage between the breaking member 612 and the braking member 43 structurally and greatly improving the anti-counterfeiting effect.

[0049] Among them, the bottle mouth 3 is a basic installation component for installing other structures. The inner cap 4 is threadedly connected to the upper part of the bottle mouth 3 and is a part for sealing the opening of the bottle mouth 3. The locking cap 6 further strengthens the connection structure between the inner cap 4 and the bottle mouth 3 and is also an important part of the combined anti-counterfeiting system composed of the inner cap 4 and the bottle mouth 3. When in use, when the braking member 43 is aligned with the relief notch 63 and the braking member 43 resets outward, when the locking cap 6 continues to rotate, the side wall of the relief notch 63 contacts the braking member 43, so that the rotational force of the locking cap 6 is transmitted to the inner cap 4, driving the inner cap 4 to rotate. It should be noted that the broken tooth key 44 has broken the broken tooth 611 before the braking member 43 is aligned with the relief notch 63.

[0050] Furthermore, the breaking piece 612 and the broken tooth 611 are an integrally formed structure, and after the broken tooth 611 is broken by the broken tooth key 44, the integrally formed structure still remains a whole with the breaking piece 612, thereby preventing the broken tooth 611 from falling off and affecting the connection and operation of other structures; a further improvement is that the number of broken teeth 611 is three, and the broken teeth 611 are distributed around the breaking piece 612 in a ring-shaped and equidistant manner, and the breaking piece 612 is an annular structure, wherein the number of mounting grooves corresponds to three, and the number of broken tooth keys 44 is also three. When the broken tooth key 44 is installed in the mounting groove, the distance between the side wall of the broken tooth key 44 and the broken tooth 611 is very small, so as to contact the broken tooth 611 faster.

[0051] The locking member 43 is then locked to the locking member 41, and the locking member 43 is locked to the locking member 41.

[0052] Furthermore, the brake member 43 is a block extending obliquely outward from the inner cover 4, and the extension distance of the brake member 43 does not exceed the brake groove. After the brake member 43 is aligned with the clearance cutout 63, the brake member 43 resets itself to an outwardly tilted state, and the hook 33 disengages from the groove 41; the brake member 43 is squeezed by the inner side wall of the skirt 62, so that it deforms inward after installation, so that the groove 41 on the brake member 43 is engaged with the hook 33, so that the inner cover 4 cannot rotate relative to the bottle mouth 3. When opening, it is only necessary to align the clearance cutout 63 and the brake member 43, and the brake member 43 can reset itself to separate the groove 41 and the hook 33. There is no need to generate force on the brake member 43 to separate the hook 33 and the groove 41, which is simpler to use.

[0053] Furthermore, the brake member 43 is made of plastic material and has a certain deformation ability. There are two brake members 43, which are symmetrically arranged on both sides of the inner cover 4 respectively. The numbers of the brake members 43, the brake grooves and the relief notches 63 correspond to each other one by one. A further improvement is that the brake member 43 is also fixedly provided with a brake member boss 47. The brake member 43 is a structure extending outward from the side surface of the brake groove to the outside of the inner cover 4. The brake member 43 is tangent to the inner cover 4 and the included angle is an acute angle, so as to facilitate the deformation of the brake member 43 towards the inside of the brake groove. The brake member boss 47 is a structure inclined outward on the brake member 43 and has a certain included angle with the initial extension direction of the brake member 43. The relief notch 63 is provided with a pushing inclined surface 69 on one side. After the locking cover 6 rotates, the pushing inclined surface 69 is inserted into the included angle between the brake member 43 and the brake member boss 47, so as to better assist the rotation of the inner cover 4.

[0054] Furthermore, on the upper side of the outer periphery of the inner cover 4, there are driven ratchet teeth 45, and on the top of the inner side of the locking cover 6, there are driving ratchet teeth 64. By the cooperation of the driving ratchet teeth 64 and the driven ratchet teeth 45, the rotation direction of the locking cover 6 relative to the inner cover 4 is limited. The rotation direction is preferably the same as the matching direction of the internal thread of the inner cover 4. By the cooperation of the driven ratchet teeth 45 and the driving ratchet teeth 64, while limiting the rotation direction, it also plays a positioning role during installation. The inner cover 4 is fixedly provided with an inner cover snap ring 48 below the driven ratchet teeth 45, and the locking cover 6 is provided with a locking cover catch 68 matching with the inner cover snap ring 48 below the driving ratchet teeth 64. Furthermore, on the upper side of the outer periphery of the inner cover 4, there are limiting ribs 46, and on the upper part of the inner side of the locking cover 6, there are blocks 65 matching with the limiting ribs 46. When the relief notch 63 of the locking cover 6 is aligned with the brake member 43, the block 65 abuts against the limiting rib 46, so that the rotation force of the locking cover 6 is transmitted to the inner cover 4, thereby driving the inner cover 4 to rotate. It should be noted that the two sets of mutually cooperating structures of the driven ratchet teeth 45 and the driving ratchet teeth 64, the limiting ribs 46 and the blocks 65 can be set separately or simultaneously. When set simultaneously, there is no interference between the driving ratchet teeth 64 and the blocks 65. Preferably, when the block 65 abuts against the limiting rib 46, the pushing inclined surface 69 is inserted into the included angle between the brake member 43 and the brake member boss 47.

[0055] Combined with Figure 1 、 Figure 12 、 Figure 13 、 Figure 14As shown, the upper end surface of the locking cover 6, the upper end surface of the destroying member 612, and the upper end surface of the tooth-breaking key 44 are located on the same horizontal plane, and are bonded with a label 7; the label 7 is an integral and destructible structure, and the label 7 can be easily destroyed when the locking cover 6 is rotated, thereby achieving an anti-counterfeiting effect; further, a truncated cone-shaped diverter plug 38 is fixedly provided on the upper side of the bottle mouth 3, and a plurality of wine outlets distributed in an annular manner are opened on the diverter plug 38, and a wine outlet is also opened on the axis of the diverter plug 38, and through the wine outlets distributed at intervals, one of the wine outlets can form an air flow channel when pouring wine, so as to keep the container The air pressure difference outside the inner cover 4 improves the smoothness of pouring wine; in contrast to the diverter plug 38, a sealing ring 49 is provided on the top of the inner cover 4 to match the diverter plug 38. The sealing ring 49 is not an annular structure, and its overall shape is a structure that fits the diverter plug 38, and forms a closed structure after matching with the diverter plug 38; at the same time, the top of the sealing ring 49 is circular, and its top surface is located on the same horizontal plane as the upper end surface of the locking cover 6. Therefore, while having a sealing effect, it also saves installation space as much as possible, makes the installation between parts more compact, and provides stability between the connection structures.

[0056] Combination Figure 3 , Figure 4 , Figure 6 , Figure 17 , Figure 18 , Figure 19 As shown, the bottle mouth 3 is provided with a hook cutout on the lower side of the external thread, and an inward "7"-shaped hook 31 is fixedly arranged on the lower side of the hook cutout, and the lateral part of the "7"-shaped hook 31 faces the outer side of the bottle mouth 3, and the bottle mouth 3 is fixed to the assembly container by the "7"-shaped hook 31; the "7"-shaped hook 31 arranged on the bottle mouth 3 is fixed to the container by the "7"-shaped hook 31; the lateral part of the "7"-shaped hook 31 makes the space for the "7"-shaped hook 31 to move outward smaller, and the required displacement distance is larger, so that the "7"-shaped hook 31 is more difficult to separate from the container, thereby improving the installation stability of the bottle mouth 3 on the container.

[0057] Furthermore, a reinforcing rib is fixedly provided between the transverse structure and the vertical structure of the "7"-shaped hook 31, one end of the reinforcing rib is fixedly connected to the bottom surface of the transverse structure of the "7"-shaped hook 31, and the other end is fixedly connected to the outer side surface of the vertical structure of the "7"-shaped hook 31, and the "7"-shaped hook 31 is reinforced by the reinforcing rib to improve stability; the "7"-shaped hook 31 has a certain elastic deformation ability, and will not break or break during a small displacement. It should be noted that the small displacement is the displacement amplitude required for the container clamp 12 that needs to pass through the container mouth 1 during installation, rather than other defined displacement amplitudes; the container mouth 1 is provided with a container card slot 11 that matches the "7"-shaped hook 31, and the shape of the container card slot 11 is adapted to the "7"-shaped hook 31. The upper side of the container card slot 11 is the deepest inwardly concave, and then a reverse thrust slope extending outward is formed downward. The reverse thrust slope can reduce the installation resistance during installation, and then the maximum resistance can be given during removal to prevent the bottle mouth 3 from being pulled out.

[0058] Furthermore, if Figure 8 As shown, a transverse rib is fixedly provided below the transverse structure of the "7"-shaped hook 31 to fix the lower side of the rib with the vertical portion of the "7"-shaped hook 31 through the transverse rib, thereby further improving the fixing and reinforcing effect of the rib. The outer side surface of the transverse rib is on the same plane as the outer side of the transverse structure of the "7"-shaped hook 31, forming a "#"-shaped structure. Through the rib and the transverse rib, the "7"-shaped hook 31 has a better overall anti-deformation ability when resisting thermal deformation.

[0059] Combination Figure 3 , Figure 4 , Figure 6 , Figure 16 , Figure 17 , Figure 18 When the bottle mouth 3 is installed on the container, the inner wall of the "7"-shaped hook 31 abuts against the container, and the inner wall of the lower tube 5 limits the outward deformation of the "7"-shaped hook 31, so that the "7"-shaped hook 31 cannot be separated from the bottle mouth 3; the "7"-shaped hook 31 of the bottle mouth 3 and the lower part of the bottle mouth 3 are covered and protected by the lower tube 5, so that the bottle mouth 3 cannot be disassembled from the outside; further, a limiting tooth 39 is fixedly provided on the lower part of the outer side of the bottle mouth 3, and a lower tube anti-rotation rib 53 cooperating with the limiting tooth 39 is fixedly provided on the inner upper side of the lower tube 5, so as to prevent the lower tube 5 and the bottle mouth 3 from rotating relative to each other; at the same time, the bottle mouth 3 is clamped on the container mouth 1, so that the bottle mouth 3 is clamped and fixed on the container mouth 1.

[0060] Another improvement is that a lower tube 5 is sleeved on the bottle mouth 3. The lower part of the bottle mouth 3 is sleeved inside the lower tube 5. The lower tube 5 is snap - fixed to the bottle mouth 3. An annular rib 54 is fixedly arranged inward at the top of the lower tube 5. A boss 42 of the inner lid 4 is fixedly arranged at the bottom of the outer periphery of the inner lid 4. The outer diameter of the boss 42 of the inner lid 4 is smaller than the inner diameter of the annular rib 54. When the lower tube 5 is installed on the bottle mouth 3, the lower end face of the annular rib 54 of the lower tube 5 abuts and cooperates with the upper end face of the boss 42 of the inner lid 4. Through the cooperation of the annular rib 54 and the boss 42 of the inner lid 4, the sequence of assembly is determined during installation. At the same time, the annular rib 54 can limit the boss 42 of the inner lid 4 below. After installation, the annular rib 54 can fix the boss 42 of the inner lid 4 and also hide the lower edge of the inner lid 4 in the lower tube 5, protecting the inner lid 4 and playing a role in preventing violent break - in, further improving the anti - counterfeiting effect. In addition, during use, because the distance between the annular rib 54 and the boss 42 of the inner lid 4 is less than the height of the threaded fit between the inner lid 4 and the bottle mouth 3, when the inner lid 4 is opened, under the action of force, the boss 42 of the inner lid 4 will be extruded above the annular rib 54. After opening, the boss 42 of the inner lid 4 can no longer return to the unopened position, so that the lower end face of the boss 42 of the inner lid 4 contacts the upper end face of the annular rib 54, forming a gap between the lower end face of the outer lid 8 and the upper end face of the inner lid 4, making the inner lid 4 of the present invention have an obvious contrast before and after opening, and more simply and directly showing whether it is in the opened state during use.

[0061] Combined with Figure 4 , Figure 5 , Figure 6 , Figure 18 As shown, a third snap ring 34 and a fourth snap ring 35 are provided at the bottom of the outer periphery of the bottle mouth 3. The fourth snap ring 35 is located below the third snap ring 34. A hook 51 of the lower tube is provided on the inner side wall of the lower tube 5. Both the third snap ring 34 and the fourth snap ring 35 can be used for snap - connection with the hook 51 of the lower tube. The third snap ring 34 is used for snap - connecting the hook 51 of the lower tube before the bottle mouth 3 is installed and fixed on the assembly container. The fourth snap ring 35 is used for snap - connecting the hook 51 of the lower tube after the bottle mouth 3 is installed and fixed on the assembly container. Through the third snap ring 34, the hook 51 of the lower tube can be initially fixed. At this time, the hook 51 of the lower tube can slide to the lower side of the fourth snap ring 35 under the action of an external force and hook the fourth snap ring 35 to further fix the bottle mouth 3 and the lower tube 5. The lower tube 5 can be snap - connected with two snap rings of the bottle mouth 3. Through two snap rings at different positions, they respectively correspond to two different states before and after the bottle mouth 3 is installed and fixed on the assembly container. In this way, all the structures before the container can be installed at one time, which is more concise than the existing structure that requires multiple installation processes, reducing costs while improving the stability of the structural cooperation. In addition, when installing, the user can simply and directly judge whether the installation is in place by whether the positions of the lower tube 5 and the outer lid 8 are changed. The installation is convenient and simple.

[0062] Combined with Figures 1 - 4 ,Figure 5 As shown in the figure, a plug 2 is clamped and fixed inside the bottle mouth 3. A second flow channel is provided inside the plug 2. The second flow channel is communicated with the first flow channel 36. A flow channel pipe 23 is provided inside the second flow channel. The axis of the flow channel pipe 23 is vertically arranged. The periphery of the flow channel pipe 23 is fixedly connected with the plug 2. The first flow channel 36 and the second flow channel form a flowable flow channel. The plug 2 is formed by connecting two pipe-like structures with a larger upper part and a smaller lower part. An outer seal ring 22 is fixedly provided on the outer periphery of the lower pipe-like structure. The double-section tubular structure not only meets the different matching requirements of the inner side of the bottle mouth 3 and the inner side of the container mouth 1, but also limits the downward displacement distance of the bottle mouth 3 through the connection part of the two pipe-like structures, avoiding the plug 2 being directly pressed into the container and providing protection for the plug 2. When the bottle mouth 3 is installed on the container mouth 1, the lower pipe-like structure of the plug 2 is inserted into the inner side of the container mouth 1, and the seal ring 22 abuts against the inner side wall of the container mouth 1 to form a sealing structure. At the same time, the second flow channel of the plug 2 is communicated with the inside of the container. The outer peripheral surface of the upper section of the plug 2 is the first matching surface 21, and the first matching surface 21 abuts against the inner side surface of the bottle mouth 3 to form a closed structure.

[0063] Furthermore, the plug 2 fixedly connects the flow channel pipe 23 through connecting pieces 24. There are multiple connecting pieces 24, and there are intervals between the connecting pieces 24. The mutually spaced connecting pieces 24 not only fix the flow channel pipe 23 on the plug 2, but also form multiple different wine outlets, thus forming different flow channels. Even further, the connecting pieces 24 are annularly distributed around the flow channel pipe 23. The annularly distributed connecting pieces 24 make the wine outlets between the connecting pieces 24 also spaced apart, making the formation route of the flow channel more reasonable.

[0064] Combined with Figure 3 、 Figure 4 、 Figure 14 、 Figure 15 As shown in the figure, it further includes an outer cover 8. The outer cover 8 is sleeved outside the locking cover 6. The outer cover 8 is clamped and fixed on the locking cover 6. A conical tooth is provided on the upper side of the outer periphery of the locking cover 6. An anti-rotation tooth 82 meshing with the conical tooth is provided inside the outer cover 8. Through the cooperation of the conical tooth and the anti-rotation tooth 82, the outer cover 8 will not rotate relative to the locking cover 6, so that the force for rotating the outer cover 8 can be directly transmitted to the locking cover 6.

[0065] Furthermore, the outer cover 8 is provided with an outer cover catch 81 on the lower side of the anti-rotation tooth 82. The locking cover 6 is successively provided with a first snap ring 66 and a second snap ring 67 on the lower side of the bevel gear. Both the first snap ring 66 and the second snap ring 67 can be used for snap connection with the outer cover catch 81. The first snap ring 66 is used for snap connection with the outer cover 8 before the bottle mouth 3 is installed and fixed on the assembly container. The second snap ring 67 is used for snap connection with the outer cover 8 after the bottle mouth 3 is installed and fixed on the assembly container. The outer cover 8 can be snap-connected with the two snap rings of the locking cover 6. Through the two snap rings at different positions, they respectively correspond to the two different states before and after the bottle mouth 3 is installed and fixed on the assembly container. Before installation and fixation, the outer cover catch 81 hooks the first snap ring 66 to achieve preliminary fixation. At this time, there is still a gap between the top surface of the inner side of the outer cover 8 and the upper end surface of the locking cover 6. This gap is the distance between the first snap ring 66 and the second snap ring 67, that is, the distance from the lower end surface of the first snap ring 66 to the lower end surface of the second snap ring 67. When the bottle mouth 3 is installed on the container mouth 1, under the action of pressure, the outer cover catch 81 changes from hooking the first snap ring 66 to hooking the second snap ring 67.

[0066] Combined with Figure 3 , Figure 4 As shown in the figure, the container mouth 1 is fixedly provided with a container convex ring 13 on the outer circumference. The container convex ring 13 is fixedly provided with a container anti-rotation rib 14 extending upward. The bottle mouth 3 is provided with a second mating portion 32 inside. The second mating portion 32 is a tubular structure. The second mating portion 32 is fixed under the shunt plug 38 and is coaxial with the shunt plug 38. The outer side surface of the second mating portion 32 is used to abut against the first mating surface 21 of the inner plug 2, thereby forming a sealed structure. The bottle mouth 3 is provided with a bottle mouth anti-rotation rib 37 under its second mating portion 32. When the bottle mouth 3 is installed on the container mouth 1, the container anti-rotation rib 14 engages with the bottle mouth anti-rotation rib 37, so that the bottle mouth 3 cannot rotate with the container mouth 1.

[0067] In the present invention, the structure formed by combining the inner plug 2, the bottle mouth 3, the inner cover 4, the lower tube 5, the locking cover 6, the label sticker 7 and the outer cover 8 is the cover body. The cover body is directly installed on the container mouth 1. Before the bottle mouth 3 is fixed on the container mouth 1, the bottle mouth 3 is threadedly connected to the inner cover 4. The inner cover 4 is snap-connected to the locking cover 6. Then, the lower tube catch 51 of the lower tube 5 hooks the third snap ring 34 of the bottle mouth 3, thereby realizing the fixation of the relative position of the lower tube 5 and the bottle mouth 3 and preventing the lower tube 5 from detaching from the bottle mouth 3. The outer cover catch 81 of the outer cover 8 hooks the first snap ring 66 of the locking cover 6, thereby relatively fixing the outer cover 8 on the locking cover 6, thus forming a completed finished product structure - the cover body. Subsequently, only by directly fixing the cover body on the container mouth 1 can all the installations be completed.

[0068] Combined with Figures 5 - 20When the bottle mouth 3 is screwed to the inner cap 4, the first and second locking ribs 32 of the bottle mouth 3 are in engagement with each other, so that the inner cap 2 is fixed to the bottle mouth 3. When the bottle mouth 3 is screwed to the inner cap 4, the first and second locking ribs 32 of the bottle mouth 3 are in engagement with each other, so that the inner cap 2 is fixed to the bottle mouth 3. After that, the locking cover 6 is pressed in, and the locking cover hook 68 hooks the lower end surface of the inner cover snap ring 48, and the broken tooth key 44 of the inner cover 4 is installed in the installation groove, and at the same time, the lower part of the skirt 62 is inserted into the gap between the annular rib 54 and the inner cover 4, and the inner side surface of the skirt 62 squeezes the brake member boss 47, and the brake member 43 moves inward, so that the inner cover 4 is locked and fixed on the bottle mouth 3, the driven ratchet 45 is meshed with the active ratchet 64, and the limiting rib 46 is installed to the upper part of the inner cover 4; 5) The label 7 is attached to the upper surface of the inner cover 4 and the locking cover 6; 6) The outer cover 8 is pressed in, and the outer cover hook 81 is engaged with the first snap ring 66, and the anti-rotation tooth 82 is meshed with the conical tooth of the locking cover 6; the assembly of the cover body is completed at this point. It should be noted that at this time, there is still a distance between the top surface of the inner side of the outer cover 8 and the label 7, and this distance is the distance between the lower end surfaces of the first snap ring 66 and the second snap ring 67.

[0069] Then, the cover body is assembled with the container mouth 1, and the container mouth 1 is inserted into the lower part of the cover body. The sealing ring 22 on the outer periphery of the inner plug 2 abuts against the inner side surface of the container mouth 1 to form a sealing structure. At the same time, the support platform of the inner plug 2 abuts against the upper end surface of the container mouth 1, so that the inner plug 2 cannot move downward; then, downward pressure is applied to the top of the outer cover 8, and the outer cover 8 moves downward under the action of the pressure, so that the outer cover hook 81 is engaged with the second clamping ring 67, and at this time, the top surface of the inner side of the outer cover 8 is in contact with the upper end surface of the locking cover 6 The outer cover 8 is touched, and the outer cover 8 no longer moves downward; at the same time, the lower tube 5 also moves downward under the action of the outer cover 8, so that the lower tube hook 51 is engaged with the fourth clamping ring 35; during installation, before the "7-shaped hook" is clamped on the container clamping ring 12, the fourth clamping ring 35 of the bottle mouth 3 does not deform inwardly, and when the "7-shaped hook" of the bottle mouth 3 is clamped into the container clamping groove 11 behind the container clamping ring 12, the fourth clamping ring 35 of the bottle mouth 3 has space for inward deformation, and the lower tube hook 51 can be smoothly clamped on the fourth clamping ring 35 of the bottle mouth 3.

For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
