Description

Technical Field

[0001] The utility model relates to the technical field of product packaging, and particularly relates to an anti-counterfeiting bottle cap and a wine bottle. Background Art

[0002] With the progress of society, people's requirements for various product packages are no longer limited to more delicate appearances, but also need to have anti-counterfeiting functions. For liquor products, especially high-end liquor products, more and more lawless elements are manufacturing fake liquor and deceiving consumers by using the packaging of genuine liquor. Therefore, various anti-counterfeiting packaging designs have become an essential production link for products.

[0003] Currently, a liquor bottle cap includes an outer cap, an inner cap, a lower tube, and a bottle mouth. The outer cap, the inner cap, and the lower tube are assembled onto the bottle mouth, and then the bottle mouth is press-fitted onto the container mouth. During the opening process, the bottle mouth, the lower tube, and the container mouth are relatively fixed, and the outer cap and the inner cap can rotate to leave the bottle mouth for pouring wine. The current anti-counterfeiting measures mostly involve anti-counterfeiting operations through structural changes in the connection between the outer cap and the inner cap and the connection between the inner cap and the lower tube. As the last step in the assembly and cooperation of the bottle cap and the container mouth, a retaining hook is usually provided on the bottle mouth, and a retaining ring is provided on the container mouth. After press-fitting, the retaining hook cooperates with the retaining ring to achieve axial limitation of the bottle mouth by the container mouth and prevent the bottle mouth from being opened. The problem with the existing technology is that there are lawless persons who heat the bottle cap, wait for the retaining hook to soften, then pull out the entire bottle cap, replace the internal liquor, and then put the bottle cap back on the bottle.

[0004] Currently, the anti-counterfeiting bottle cap usually also has a fracture anti-counterfeiting structure. However, in the usage scenario of liquor, the fractured anti-counterfeiting part may fall on dishes, wine glasses, or clothes. If not careful, there may be a risk of accidental ingestion, posing a safety hazard. Summary of the Utility Model

[0005] To overcome the problem that the existing bottle cap can be pulled out as a whole after heating, the utility model provides an anti-counterfeiting bottle cap and a wine bottle.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0007] The anti-counterfeiting bottle cap includes a bottle mouth, a lower tube, and an opening component. The lower tube is fixedly connected to the lower section of the bottle mouth, and the opening component is rotatably connected to the upper section of the bottle mouth. A lower retaining hook is connected to the bottle mouth for cooperating with the bottle lip of the container mouth to limit the axial movement of the bottle mouth relative to the container mouth. The lower retaining hook is provided with a plurality of them, and the upper ends of the plurality of lower retaining hooks are connected to form a retaining hook component. The plurality of lower retaining hooks are evenly distributed in the circumferential direction of the bottle mouth. The retaining hook component is fixedly connected to the bottle mouth, and a retaining hook window is correspondingly provided on the bottle mouth; each lower retaining hook includes an inner mating inclined surface and an outer mating surface. When the bottle mouth is assembled to the container mouth, the mating inclined surface of each lower retaining hook abuts against the container mouth in the retaining hook window, and the mating surface of each lower retaining hook abuts against the inner wall of the lower tube.

[0008] In the present application, multiple lower engaging hooks are independently arranged relative to the bottle mouth and are connected to form an engaging hook member. On the one hand, it is convenient for processing and implementation, and on the other hand, it is beneficial to ensure uniform distribution in the circumferential direction. A hook window is opened on the bottle mouth. After the bottle cap is assembled, that is, when the bottle mouth is assembled to the container mouth, the inner and outer sides of the lower engaging hook respectively abut against the container mouth and the lower tube, so that the lower engaging hook has no deformation space, making it impossible to pull off the bottle cap and also impossible to reattach the bottle cap to the bottle, thereby enhancing the anti-counterfeiting effect. The multiple lower engaging hooks are connected below the engaging hook member to prevent the lower engaging hooks from being damaged by the downward pressure during the pressing process of the bottle cap when the lower engaging hooks are arranged above.

[0009] Further, a first bottle retaining ring and a second bottle retaining ring are arranged on the outer wall of the lower section of the bottle mouth. The first bottle retaining ring is arranged above the second bottle retaining ring. A lower tube engaging hook is correspondingly arranged on the inner wall of the lower tube. The lower tube has two sections with different inner wall sizes. The section with a smaller inner wall size is section A, and the section with a larger inner wall size is section B. Section A is located above section B. When the bottle mouth is assembled to the container mouth, the lower tube engaging hook cooperates with the second bottle retaining ring, and the height where the lower engaging hook is located corresponds to section A, and the mating surface of each lower engaging hook abuts against the inner wall of section A.

[0010] In this embodiment, considering that after the bottle cap is pressed, the space between the container mouth and the lower tube is filled by the lower engaging hook. In order to balance the relative fixed limit of each component before pressing and the installability of the bottle cap, the first bottle retaining ring and the second bottle retaining ring are set to achieve the axial limit of the bottle mouth to the lower tube in two stages before and after pressing. Supplementary to the change in the wall thickness of the lower tube, as in the above embodiment, before the bottle mouth and the container mouth are matched, the lower tube engaging hook cooperates with the first bottle retaining ring, and the bottle mouth axially limits the lower tube, facilitating the overall movement of the two and the subsequent pressing process. When the bottle mouth and the container mouth are matched, the lower tube is pressed downward, and the pressing process makes the lower tube engaging hook cooperate with the second bottle retaining ring, realizing that the lower engaging hook abuts between the inner wall section A of the lower tube and the container mouth after assembly.

[0011] Further, the multiple lower engaging hooks naturally open obliquely outward. When the lower tube engaging hook cooperates with the first bottle retaining ring, the height where the lower engaging hook is located corresponds to section B, and the lower engaging hook is in a natural state. When the lower tube engaging hook cooperates with the second bottle retaining ring, the height where the lower engaging hook is located corresponds to section A, and section A of the lower tube abuts against the lower engaging hook, causing the lower engaging hook to move inward, thereby realizing the abutment between the mating inclined surface of the lower engaging hook and the container mouth.

[0012] In this embodiment, the engaging hook member includes multiple lower engaging hooks that naturally open obliquely outward. Before pressing, the height where the engaging hook member is located cooperates with section B of the lower tube to facilitate the installation of the bottle cap relative to the container mouth. During pressing, the lower tube moves downward, and section A of the lower tube abuts against the lower engaging hook, causing the lower engaging hook to move inward and abut between the container mouth and section A of the lower tube.

[0013] Further, the opening cover assembly includes an inner cover, which is threadedly connected to the upper section of the bottle mouth. An anti-resetting ring is provided at the lower end of the inner cover, and a lower tube stop ring is provided at the upper end of the lower tube. After the bottle cap is assembled, the anti-resetting ring is located above the lower tube stop ring. During the opening process, the inner cover rotates relative to the bottle mouth, causing the anti-resetting ring to pop out of the lower tube stop ring.

[0014] In this embodiment, through the cooperation of the anti-resetting ring and the lower tube stop ring, during the opening process, the anti-resetting ring pops out of the lower stop ring. When the inner cover is screwed back, the lower stop ring limits the anti-resetting ring, and the inner cover cannot be installed back to the initial position to provide an anti-counterfeiting effect.

[0015] Further, a stop groove is provided on the thread section of the bottle mouth connected to the inner cover. A hook is correspondingly provided on the side wall of the inner cover, and the hook penetrates the side wall of the inner cover. The opening cover assembly further includes a connecting member sleeved outside the inner cover. An elastic opening window is provided on the side wall of the connecting member, and an outer dialing boss is connected at the elastic opening window on the inner wall of the connecting member. After the bottle cap is assembled, the hook cooperates with the stop groove under the abutment of the inner wall of the connecting member, so that the inner cover and the bottle mouth cannot rotate relative to each other. When the connecting member rotates relative to the inner cover, the outer dialing boss cooperates with the hook, causing the hook to move outwards through the elastic opening window, thereby contacting the limiting cooperation of the hook and the stop groove, and enabling the inner cover to rotate relative to the bottle mouth.

[0016] In this embodiment, the inner cover and the bottle mouth are correspondingly provided with a stop groove and a hook as above, so that when the hook of the inner cover and the stop groove of the bottle mouth cooperate, the inner cover cannot rotate relative to the bottle mouth. And a connecting member is added. An elastic opening window and an outer dialing boss are provided on the connecting member, so that during the relative rotation of the connecting member and the inner cover, the outer dialing boss can dial the hook of the bottle mouth outwards, thereby releasing the limiting cooperation of the hook and the stop groove. Furthermore, the rotation of the connecting member can drive the inner cover to rotate synchronously to achieve the opening action.

[0017] Further, the opening cover assembly further includes an outer cover sleeved outside the connecting member. Outer cover anti-rotation ribs are vertically provided on the inner wall of the outer cover, and connecting member anti-rotation ribs are correspondingly provided on the outer wall of the connecting member. A connecting first ring and a connecting second ring are provided on the outer wall of the connecting member. The connecting first ring is provided above the connecting second ring, and outer cover hooks are correspondingly provided on the inner wall of the outer cover. When the outer cover hook cooperates with the connecting first ring, and the lower tube hook cooperates with the bottle first ring, the outer cover and the lower tube abut, so that a force perpendicular to the axis of the bottle mouth can be transmitted from the outer cover to the lower tube. Pressing and installing the outer cover can achieve the cooperation of the outer cover hook and the connecting second ring, and at the same time achieve the cooperation of the lower tube hook and the bottle second ring.

[0018] In this embodiment, an outer cover is added and sleeved outside the connecting piece to prevent the mating structure from being exposed, making the overall outer surface of the bottle cap more regular and preventing the anti-counterfeiting structure from being exposed; an anti-rotation rib for the outer cover and an anti-rotation rib for the connecting piece are added to prevent relative rotation between the outer cover and the connecting piece; a first connecting ring and a second connecting ring are added to axially limit the outer cover by the connecting piece and link the cooperation between the aforementioned lower tube and the bottle mouth, so that during the pressing process, pressing the outer cover directly can achieve the pressing of the lower tube.

[0019] Furthermore, it further includes an anti-counterfeiting part and a decorative part. The decorative part is rotatably sleeved on the outer periphery of the lower tube. A guiding chute is provided on the outer wall of the lower tube, a guiding shaft is correspondingly arranged on the inner side of the anti-counterfeiting part, and an anti-counterfeiting part moving groove is provided on the inner wall of the decorative part; a rotating boss is provided at the lower end of the outer cover, a rotating groove is correspondingly arranged at the upper end of the decorative part, and an anti-counterfeiting window is further provided at the lower end of the outer cover for the initial position assembly of the anti-counterfeiting part; when the outer cover rotates, the decorative part is driven to move through the rotating boss and the rotating groove. Under the rotation of the decorative part, the anti-counterfeiting part moves downward under the common limitation of the guiding chute and the anti-counterfeiting part moving groove. After the opening action is completed, the anti-counterfeiting part is completely blocked between the decorative part and the lower tube.

[0020] In this embodiment, an anti-counterfeiting part and a decorative part are added. The initial position of the anti-counterfeiting part, that is, it can be seen before opening the cap. During the process of opening the cap, it is hidden between the decorative part and the lower tube to provide an anti-counterfeiting effect; and the anti-counterfeiting part is hidden during the process of opening the cap and does not protrude from the bottle cap, improving the safety during use.

[0021] Furthermore, the upper end of the guiding chute has a vertical section. A fixed shaft is provided on the inner side of the anti-counterfeiting part, and a positioning hole is correspondingly arranged on the outer wall of the lower tube; when the anti-counterfeiting part is fixedly connected to the lower tube through the cooperation of the fixed shaft and the positioning hole, the anti-counterfeiting part is located on the vertical section of the guiding chute. When the outer cover is assembled relative to the lower tube, the outer cover abuts against the anti-counterfeiting part, causing the fixed shaft to be damaged, and the anti-counterfeiting part disengages from the vertical section of the guiding chute, and the anti-counterfeiting part can rotate downward along with the decorative part.

[0022] In this embodiment, through the vertical section at the upper end of the guiding chute and the cooperation of the fixed shaft and the positioning hole, the fixed connection between the anti-counterfeiting part and the lower tube can be realized, avoiding the inability to position the anti-counterfeiting part when the decorative part is not installed. During the assembly of the outer cover, the fixed shaft is damaged, causing the anti-counterfeiting part to enter the lower end of the guiding chute and can rotate downward along with the decorative part.

[0023] Furthermore, before opening the cap, the upper end surfaces of the connecting piece and the inner cap are flush, and an RFID tag is connected to the upper end surfaces of the connecting piece and the inner cap.

[0024] In this embodiment, before opening the cap, the upper end surfaces of the connecting piece and the inner cap are flush, and an RFID tag is affixed across the seam. When relative rotation occurs between the connecting piece and the inner cap, the RFID tag is damaged, thereby providing an anti-counterfeiting effect.

[0025] Further, a rising boss is provided on the inner wall of the connecting piece, a rising chute is correspondingly opened on the outer wall of the inner cap, a connecting piece ratchet tooth is provided on the inner wall of the connecting piece, and an inner cap ratchet tooth is correspondingly arranged on the outer wall of the inner cap; when the connecting piece rotates relative to the inner cap, when the rising boss moves to the upper section of the rising chute, the outer dialing boss cooperates with the hook, so that the inner cap can rotate relative to the bottle mouth, and the connecting piece ratchet tooth and the inner cap ratchet tooth cooperate to form a one-way ratchet structure.

[0026] In this embodiment, the relative rotation of the inner cap and the connecting piece is realized through the rising boss and the rising chute; during the process of opening the cap, the connecting piece rotates relative to the inner cap first. After rotating a certain stroke, the outer dialing boss releases the cooperation between the hook and the stop, so that the connecting piece can drive the inner cap to rotate synchronously. At the same time, the cooperation between the connecting piece ratchet tooth and the inner cap ratchet tooth prevents the relative rotation between the connecting piece and the inner cap in the reverse direction of opening the cap after opening the cap, achieving an anti-counterfeiting effect.

[0027] The present utility model further provides a wine bottle, which includes a container mouth and also includes the anti-counterfeiting bottle cap described in any one of the above embodiments. The upper end of the container mouth is a bottle lip, and an outer pushing slope is concavely formed below the bottle lip. When the bottle mouth is assembled to the container mouth, the mating slope of each lower hook abuts against the outer pushing slope; an anti-rotation rib of the container mouth is further provided on the outer wall of the container mouth, and an inner anti-rotation rib is correspondingly arranged on the inner wall of the bottle mouth.

[0028] In this embodiment, the lower hook is limited by the outer pushing slope and the inner wall of the lower tube; the bottle mouth and the container mouth are further fixedly connected through the anti-rotation rib of the container mouth and the inner anti-rotation rib.

[0029] The beneficial effects of the present utility model are:

[0030] 1. Multiple lower hooks are independently arranged relative to the bottle mouth and connected to form a hook member. On the one hand, it is convenient for processing and implementation, and on the other hand, it is beneficial to ensure uniform distribution in the circumferential direction; a hook window is opened on the bottle mouth. After the bottle cap is assembled and when the bottle mouth is assembled to the container mouth, the inner and outer sides of the lower hook respectively abut against the container mouth and the lower tube, so that the lower hook has no deformation space, making the bottle cap unable to be pulled off and unable to be put on the bottle again, so as to improve the anti-counterfeiting effect; multiple lower hooks are connected below the hook member, avoiding damage to the lower hook caused by the downward pressure during the press-fitting process of the bottle cap when the lower hook is arranged above.

[0031] 2. The first bottle ring and the second bottle ring are provided to realize the axial limit of the bottle mouth to the lower tube in two stages before and after press-fitting; supplemented by the change in the wall thickness of the lower tube, as described above, before the bottle mouth and the container mouth are matched, the lower tube hook and the first bottle ring cooperate, and the bottle mouth realizes axial limit to the lower tube, facilitating the overall movement of the two and the subsequent press-fitting process; when the bottle mouth and the container mouth are matched, the lower tube is pressed downwards, and the press-fitting process makes the lower tube hook and the second bottle ring cooperate, so that after assembly, the lower hook abuts between the A section of the inner wall of the lower tube and the container mouth, taking into account the relative fixation before press-fitting and the installability of the bottle cap.

[0032] 3. The open cap assembly is provided with multiple anti-counterfeiting structures. For example, after the inner cap is screwed out, the anti-reset ring cannot return to its initial position; the outer cap needs to rotate a certain stroke to drive the inner cap to rotate; only one-way rotation can be achieved between the inner cap and the connecting piece; an RFID tag is affixed across the seam between the connecting piece and the upper top surface of the inner cap.

[0033] 4. The anti-counterfeiting effect is further enhanced by adding anti-counterfeiting parts; the anti-counterfeiting parts are recessed between the decorative part and the lower tube during the opening process of the cap to avoid falling outside the bottle cap, so as to improve the use safety.

Detailed implementation mode

[0065] The present invention will be further described below with reference to the accompanying drawings.

[0066] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0067] As Figure 1-27 shown, the present invention provides an anti-counterfeiting bottle cap.

[0068] Anti-counterfeiting bottle cap, comprising a bottle mouth 5, a lower tube 9 and an opening component. The lower tube 9 is fixedly connected to the lower section of the bottle mouth 5, and the opening component is rotatably connected to the upper section of the bottle mouth 5. A lower catch 44 is connected to the bottle mouth 5 for cooperating with the bottle lip 101 of the container mouth 10 to limit the axial movement of the bottle mouth 5 relative to the container mouth 10. A plurality of lower catches 44 are provided, and the upper ends of the plurality of lower catches 44 are connected to form a catch member 4. The plurality of lower catches 44 are evenly distributed in the circumferential direction of the bottle mouth 5. The catch member 4 is fixedly connected to the bottle mouth 5, and a catch window 57 is correspondingly provided on the bottle mouth 5; each lower catch 44 comprises an inner mating inclined surface 46 and an outer mating surface 45. When the bottle mouth 5 is assembled to the container mouth 10, the mating inclined surface 46 of each lower catch 44 abuts against the container mouth 10 in the catch window 57, and the mating surface 45 of each lower catch 44 abuts against the inner wall of the lower tube 9.

[0069] In the present application, the plurality of lower catches 44 are independently arranged relative to the bottle mouth 5 and connected to form the catch member 4. On the one hand, it is convenient for processing and implementation, and on the other hand, it is beneficial to ensure the uniform distribution in the circumferential direction; a catch window 57 is opened on the bottle mouth 5. After the bottle cap is assembled and when the bottle mouth 5 is assembled to the container mouth 10, the inner and outer sides of the lower catch 44 respectively abut against the container mouth 10 and the lower tube 9, so that the lower catch 44 has no deformation space, making the bottle cap unable to be pulled off and also unable to be put on the bottle again, so as to improve the anti-counterfeiting effect; the plurality of lower catches 44 are connected below the catch member 4 to prevent the lower catches 44 from being damaged by the downward pressure during the press-fitting process of the bottle cap when the lower catches 44 are arranged above.

[0070] Preferably, the catch member 4 has characteristics such as high strength and high temperature resistance.

[0071] There are various implementation manners for the catch member 4 to be fixedly connected to the bottle mouth 5, and conventional fixing means can all be realized. In this embodiment, the catch member 4 further comprises an upper catch 41, and a third bottle ring 56 is correspondingly provided on the bottle mouth 5. When the catch member 4 is installed in place relative to the bottle mouth 5, the upper catch 41 and the third bottle ring 56 cooperate to limit the upward movement of the catch member 4 in the axial direction relative to the bottle mouth 5; the catch member 4 is also provided with a positioning groove 43, and a positioning boss 52 is correspondingly provided on the bottle mouth 5. The two cooperate with each other to facilitate the positioning and installation of the catch member 4 relative to the bottle mouth 5, and the positioning groove 43 and the positioning boss 52 cooperate to limit the downward movement of the catch member 4 in the axial direction relative to the bottle mouth 5.

[0072] Further, a first bottle retaining ring 54 and a second bottle retaining ring 55 are provided on the outer wall of the lower part of the bottle mouth 5. The first bottle retaining ring 54 is arranged above the second bottle retaining ring 55. A lower tube catch 98 is correspondingly provided on the inner wall of the lower tube 9. The lower tube 9 has two sections with different inner wall dimensions. The section with a smaller inner wall dimension is section A, and the section with a larger inner wall dimension is section B. Section A is located above section B. When the bottle mouth 5 is assembled to the container mouth 10, the lower tube catch 98 cooperates with the second bottle retaining ring 55. The height where the lower catch 44 is located corresponds to section A. The mating surface 45 of each lower catch 44 abuts against the inner wall of section A.

[0073] In this embodiment, considering that after the bottle cap is press-fitted, the space between the container mouth 10 and the lower tube 9 is filled by the lower catches 44. To balance the relative fixed limit of each component before press-fitting and the installability of the bottle cap, the first bottle retaining ring 54 and the second bottle retaining ring 55 are provided to achieve the axial limit of the bottle mouth 5 to the lower tube 9 in two stages before and after press-fitting; supplemented by the change in the wall thickness of the lower tube 9 as described above, before the bottle mouth 5 and the container mouth 10 are mated, the lower tube catch 98 cooperates with the first bottle retaining ring 54, and the bottle mouth 5 axially limits the lower tube 9, facilitating the overall movement of the two and the subsequent press-fitting process; when the bottle mouth 5 and the container mouth 10 are mated, the lower tube 9 is pressed downward. During the press-fitting process, the lower tube catch 98 cooperates with the second bottle retaining ring 55, so that after assembly, the lower catch 44 abuts between the inner wall section A of the lower tube 9 and the container mouth 10.

[0074] The aforementioned first bottle retaining ring 54, second bottle retaining ring 55 and lower tube catch 98 are used for the axial limit of the bottle mouth 5 and the lower tube 9. Circumferentially, an outer anti-rotation rib 53 is provided on the outer wall of the bottle mouth 5, and a lower tube anti-rotation rib 91 is correspondingly provided on the inner wall of the lower tube 9. The two cooperate to achieve the rotational limit in the circumferential direction. Further, for the convenience of installation and implementation, a guiding rib 42 is correspondingly provided on the catch member 4. After the catch member 4 and the bottle mouth 5 are installed, the position of the guiding rib 42 corresponds to that of the outer anti-rotation rib 53.

[0075] In some embodiments, as Figure 28-30 shown, multiple lower catches 44 are naturally inclined and open outward. When the lower tube catch 98 cooperates with the first bottle retaining ring 54, the height where the lower catch 44 is located corresponds to section B, and the lower catch 44 is in a natural state; when the lower tube catch 98 cooperates with the second bottle retaining ring 55, the height where the lower catch 44 is located corresponds to section A, and section A of the lower tube 9 abuts against the lower catch 44, causing the lower catch 44 to move inward, so as to achieve the abutment of the mating inclined surface 46 of the lower catch 44 and the container mouth 10. In this embodiment, the catch member 4 includes multiple lower catches 44 that are naturally inclined and open outward. Before press-fitting, the height where the catch member 4 is located cooperates with section B of the lower tube 9 to facilitate the installation of the bottle cap relative to the container mouth 10; during press-fitting, the lower tube 9 moves downward, and section A of the lower tube 9 abuts against the lower catch 44, causing the lower catch 44 to move inward and abut between the container mouth 10 and section A of the lower tube 9.

[0076] Furthermore, the opening component includes an inner cap 3, which is threadedly connected to the upper section of the bottle mouth 5. A reset prevention ring 34 is provided at the lower end of the inner cap 3, and a lower tube stop ring 99 is provided at the upper end of the lower tube 9. After the bottle cap is assembled, the reset prevention ring 34 is located above the lower tube stop ring 99. During the opening process, the inner cap 3 rotates relative to the bottle mouth 5, causing the reset prevention ring 34 to pop out of the lower tube stop ring 99.

[0077] In this embodiment, through the cooperation of the reset prevention ring 34 and the lower tube stop ring 99, during the opening process, the reset prevention ring 34 pops out of the lower stop ring. When the inner cap 3 rotates back, the lower stop ring forms a limit on the reset prevention ring 34, and the inner cap 3 cannot be installed back to its initial position to provide an anti-counterfeiting effect.

[0078] Furthermore, a stop groove 51 is provided on the threaded section of the bottle mouth 5 connected to the inner cap 3. A hook 32 is correspondingly provided on the side wall of the inner cap 3, and the hook 32 penetrates the side wall of the inner cap 3. The opening component further includes a connecting piece 2 sleeved outside the inner cap 3. A lifting window 26 is provided on the side wall of the connecting piece 2, and an outer lifting boss 27 is connected at the lifting window 26 on the inner wall of the connecting piece 2. After the bottle cap is assembled, the hook 32 cooperates with the stop groove 51 under the abutment of the inner wall of the connecting piece 2, so that the inner cap 3 and the bottle mouth 5 cannot rotate relative to each other. When the connecting piece 2 rotates relative to the inner cap 3, the outer lifting boss 27 cooperates with the hook 32, causing the hook 32 to move outwards through the lifting window 26, thereby releasing the limiting cooperation between the hook 32 and the stop groove 51, and enabling the inner cap 3 to rotate relative to the bottle mouth 5.

[0079] In this embodiment, the stop groove 51 and the hook 32 are correspondingly provided on the inner cap 3 and the bottle mouth 5 as described above, so that when the hook 32 of the inner cap 3 cooperates with the stop groove 51 of the bottle mouth 5, the inner cap 3 cannot rotate relative to the bottle mouth 5. And a connecting piece 2 is additionally provided, with a lifting window 26 and an outer lifting boss 27 provided on the connecting piece 2. During the relative rotation of the connecting piece 2 and the inner cap 3, the outer lifting boss 27 can push the hook 32 of the bottle mouth 5 outwards, thereby releasing the limiting cooperation between the hook 32 and the stop groove 51. Furthermore, the rotation of the connecting piece 2 can drive the inner cap 3 to rotate synchronously to achieve the opening action.

[0080] Furthermore, the opening component further includes an outer cap 1 sleeved outside the connecting piece 2. Outer cap anti-rotation ribs 13 are vertically provided on the inner wall of the outer cap 1, and corresponding connecting piece anti-rotation ribs 22 are provided on the outer wall of the connecting piece 2. A connecting first ring 23 and a connecting second ring 24 are provided on the outer wall of the connecting piece 2, and the connecting first ring 23 is provided above the connecting second ring 24. Outer cap hooks 14 are correspondingly provided on the inner wall of the outer cap 1. When the outer cap hooks 14 cooperate with the connecting first ring 23, and the lower tube hook 98 cooperates with the bottle first ring 54, the outer cap 1 abuts against the lower tube 9, enabling the outer cap 1 to transmit a force perpendicular to the axis of the bottle mouth 5 to the lower tube 9. Pressing and installing the outer cap 1 can achieve the cooperation between the outer cap hooks 14 and the connecting second ring 24, and at the same time achieve the cooperation between the lower tube hook 98 and the bottle second ring 55.

[0081] In this embodiment, an outer cover 1 is added and sleeved outside the connecting piece 2 to prevent the mating structure from being exposed, making the overall outer surface of the bottle cap more regular and preventing the anti-counterfeiting structure from being exposed; an anti-rotation rib 13 of the outer cover and an anti-rotation rib 22 of the connecting piece are added to prevent the outer cover 1 and the connecting piece 2 from rotating relative to each other; a first connecting ring 23 and a second connecting ring 24 are added to axially limit the outer cover 1 by the connecting piece 2 and link the mating of the aforementioned lower tube 9 and the bottle mouth 5, so that during the pressing process, pressing the outer cover 1 directly can achieve the pressing of the lower tube 9.

[0082] Furthermore, an anti-counterfeiting part 7 and a decorative part 8 are further included. The decorative part 8 is rotatably sleeved on the outer periphery of the lower tube 9. A guiding chute 95 is formed on the outer wall of the lower tube 9. A guiding shaft 71 is correspondingly arranged on the inner side of the anti-counterfeiting part 7. An anti-counterfeiting part moving groove 86 is formed on the inner wall of the decorative part 8; a rotating boss 12 is arranged at the lower end of the outer cover 1. A rotating groove 81 is correspondingly arranged at the upper end of the decorative part 8. An anti-counterfeiting window 11 is also arranged at the lower end of the outer cover 1 for assembling the initial position of the anti-counterfeiting part 7; when the outer cover 1 rotates, the decorative part 8 is driven to move through the rotating boss 12 and the rotating groove 81. Under the rotation of the decorative part 8, the anti-counterfeiting part 7 moves downward under the common limitation of the guiding chute 95 and the anti-counterfeiting part moving groove 86. After the opening action is completed, the anti-counterfeiting part 7 is completely blocked between the decorative part 8 and the lower tube 9.

[0083] In this embodiment, an anti-counterfeiting part 7 and a decorative part 8 are added. The initial position of the anti-counterfeiting part 7, that is, it can be seen before opening the cap, is hidden between the decorative part 8 and the lower tube 9 during the opening process to provide an anti-counterfeiting effect; and the anti-counterfeiting part 7 is hidden during the opening process and does not protrude from the bottle cap, improving the safety during use.

[0084] Specifically, in this embodiment, based on the fact that the anti-counterfeiting part 7 is pre-installed on the lower tube 9 and the anti-counterfeiting part 7 can move along the guiding chute 95 on the lower tube 9, in order to facilitate the assembly and fixation of the anti-counterfeiting part 7, a fixing shaft 72 is further arranged on the inner side of the anti-counterfeiting part 7, and a positioning hole 96 is correspondingly arranged on the lower tube 9. After the decorative part 8 is installed in this way, the anti-counterfeiting part moving groove 86 and the guiding chute 95 on the decorative part 8 jointly limit the anti-counterfeiting part 7. To realize the movement of the anti-counterfeiting part 7, the fixing shaft 72 needs to be damaged. The damage method in this embodiment is to press down the outer cover 1, and the outer cover 1 transmits pressure to damage the fixing shaft 72. Therefore, the initial stage of the guiding chute 95 in the figure includes a section vertically downward.

[0085] A decorative part catch 83 is arranged on the decorative part 8, and a lower tube retaining ring 93 is correspondingly arranged on the lower tube 9 to achieve axial limitation; a decorative part positioning groove 85 is formed in the middle of the decorative part catch 83 on the decorative part 8, and a positioning rib is correspondingly arranged on the lower tube retaining ring 93 to make the position of the decorative part 8 installed on the lower tube 9 relatively fixed, so as to ensure that the decorative part 8 can drive the hiding of the anti-counterfeiting part 7 during the rotation process.

[0086] A stopper 84 is provided on the decorative member 8, and a corresponding stopper 97 is provided on the lower tube 9 to limit the end travel of the relative rotation of the decorative member 8 and the lower tube 9. The decorative member 8 is also provided with a decorative member ratchet 82, and a corresponding lower tube ratchet 94 is provided on the lower tube 9. When the stopper 84 and the stopper 97 engage, the decorative member ratchet 82 and the lower tube ratchet 94 also engage. Preferably, in this embodiment, the stopper 97 is formed at one end of the lower tube clamp 93.

[0087] Furthermore, before the cover is opened, the upper end surfaces of the connector 2 and the inner cover 3 are flush, and the upper end surfaces of the connector 2 and the inner cover 3 are connected with an RFID tag 0.

[0088] In this embodiment, before the cover is opened, the upper end surfaces of the connector 2 and the inner cover 3 are flush, and an RFID tag 0 is affixed to the seam. When the connector 2 and the inner cover 3 rotate relative to each other, the RFID tag 0 is damaged, thereby providing an anti-counterfeiting effect.

[0089] Obviously, a through hole should be opened on the upper end surface of the outer cover 1 so that consumers can see the RFID tag 0 below.

[0090] Furthermore, a rising boss 28 is provided on the inner wall of the connecting member 2, and a corresponding rising groove 33 is provided on the outer wall of the inner cover 3. A connecting member ratchet 21 is provided on the inner wall of the connecting member 2, and an inner cover ratchet 31 is provided on the outer wall of the inner cover 3; when the connecting member 2 rotates relative to the inner cover 3, the rising boss 28 moves to the upper section of the rising groove 33, the outward boss 27 cooperates with the hook 32, so that the inner cover 3 can rotate relative to the bottle mouth 5, and the connecting member ratchet 21 and the inner cover ratchet 31 cooperate to form a one-way ratchet structure.

[0091] In this embodiment, the relative rotation of the inner cover 3 and the connecting member 2 is achieved by the rising boss 28 and the rising slot 33; during the opening process, the connecting member 2 first rotates relative to the inner cover 3. After rotating for a certain distance, the outward boss 27 releases the cooperation between the hook 32 and the stop 51, so that the connecting member 2 can drive the inner cover 3 to rotate synchronously. At the same time, the cooperation between the connecting member ratchet 21 and the inner cover ratchet 31 prevents the connecting member 2 and the inner cover 3 from rotating relative to each other in the opposite direction of opening the cover after opening the cover, thereby achieving an anti-counterfeiting effect.

[0092] A vertical upward fracture groove 25 is further provided at the lower end of the connecting member 2 to facilitate the positioning and assembly of the connecting member 2 relative to the inner cover 3.

[0093] Preferably, as shown in the figure, the connector ratchet 21 is set at the inner top and the inner cover ratchet 31 is set at the outer top. When assembled in place, the connector ratchet 21 and the inner cover ratchet 31 are located between the connector 2 and the inner cover 3. After engagement, they cannot be restored from the outside by other means.

[0094] The present utility model further provides a wine bottle, which includes a container mouth 10. The upper end of the container mouth 10 is a bottle lip 101, and an outward-pushing inclined surface 103 is formed by inward concavity below the bottle lip 101. When the bottle mouth 5 is assembled to the container mouth 10, the mating inclined surface 46 of each lower catch 44 abuts against the outward-pushing inclined surface 103. An anti-rotation rib 102 of the container mouth is further provided on the outer wall of the container mouth 10, and an inner anti-rotation rib 59 is correspondingly provided on the inner wall of the bottle mouth 5.

[0095] In this embodiment, the lower catch 44 is limited by the outward-pushing inclined surface 103 and the inner wall of the lower tube 9; the bottle mouth 5 and the container mouth 10 are further fixedly connected by the anti-rotation rib 102 of the container mouth and the inner anti-rotation rib 59.

[0096] After the bottle cap is assembled, when the bottle cap is subjected to a pulling-off force, the mating inclined surface 46 of the catch member 4 cooperates with the outward-pushing inclined surface 103 of the glass bottle container mouth 10, causing the lower catch 44 to have a tendency to push outward. However, since the mating surface 45 of the lower catch 44 abuts against the inner wall surface of the lower tube 9, it cannot be deformed outward, so that the bottle cap cannot be pulled off.

[0097] The anti-counterfeiting bottle cap further includes an inner plug 6, and a wine outlet hole 61 is provided on the inner plug 6. During the assembly process of the bottle cap, the inner plug 6 is inserted into the bottle mouth 5 and cooperates with the diversion column 58 of the bottle mouth 5. A wine outlet 50 is provided on the bottle mouth 5. This is prior art and will not be elaborated here.

[0098] The assembly process of the anti-counterfeiting bottle cap in this embodiment is as follows: 1. Install the hook member 4 into the bottle mouth 5, so that the positioning groove 43 of the hook member 4 cooperates with the positioning boss 52 of the bottle mouth 5, the lower hook 44 cooperates with the hook window 57, and the upper hook 41 of the hook member 4 is clamped under the third clamping ring 56 of the bottle mouth 5; 2. Install the inner plug 6 into the bottle mouth and cooperate with the guide column 58; 3. Screw in the inner cover 3, so that the hook 32 of the inner cover 3 cooperates with the stop 51 of the bottle mouth 5; 4. Install the anti-counterfeiting part 7 onto the lower tube 9, so that the fixed shaft 72 cooperates with the positioning hole 96, and the guide slide shaft 71 cooperates with the guide slide groove 95; 5. Assemble the decorative part positioning groove 85 along the positioning rib 92 of the lower tube 9, and install the decorative part 8. At this time, the anti-counterfeiting part 7 cooperates with the anti-counterfeiting part moving groove 86 on the decorative part 8 and is assembled to the decorative part hook 83 and the lower tube clamp ring 93 match; 6. Install the lower tube 9 onto the bottle mouth 5, so that the lower tube hook 98 is stuck in the first bottle clamp ring 54, and the lower tube anti-rotation rib 91 and the guide rib 42 on the hook member 4 match; 7. Press the rising boss 28 of the connector 2 downward along the inner cover 3 so that the rising boss 28 of the connector 2 and the rising slide 33 of the inner cover 3 match; 8. Attach the RFID tag 0 on the connector 2 and the inner cover 3; 9. Install the outer cover 1, first match the anti-counterfeiting window 11 of the outer cover 1 with the anti-counterfeiting part 7, press the cover to break the fixed axis 72 of the anti-counterfeiting part 7, and move the anti-counterfeiting part 7 downward, the outer cover hook 14 and the first connecting clamp ring 23 match, the outer cover anti-rotation rib 13 and the connector anti-rotation rib 22 match, and the outer cover 1 rotating boss 12 and the decorative part 8 rotating groove 81 match. After completing the above steps, perform the bottle loading operation and press the bottle cap as a whole onto the container mouth 10. First, the lower tube 9 is pre-inserted into the container mouth 10, and the inner plug 6 enters the inner diameter of the container mouth 10. The upper and lower hooks 44 of the hook member 4 deform outward and engage the bottle lip 101 of the container mouth 10. Then, the bottle cap is subjected to continued downward pressure, and the outer cap hook 14 moves downward from the first hook 23 to the second hook 24. Simultaneously, the lower tube hook 98 moves downward from the first hook 54 to the second hook 55. The inner diameter of the lower tube 9 embraces the lower hook 44. At this point, the bottle cap is assembled and the bottle is loaded.

[0099] In this embodiment, the opening process of the anti-counterfeiting bottle cap is as follows: 1. Rotate the outer cap 1. The rotating boss 12 of the outer cap 1 drives the rotating groove 81 of the decorative part 8 to rotate. The guiding slide shaft 71 of the anti-counterfeiting part 7 cooperates with the guiding chute 95 of the lower tube 9, and the anti-counterfeiting part 7 cooperates with the anti-counterfeiting part moving groove 86 on the decorative part 8, so that the anti-counterfeiting part 7 spirally moves downward until it is completely hidden; at the same time, the outer cap 1 drives the connecting part 2 to rotate, and the rising boss 28 of the connecting part 2 and the rising chute 33 of the inner cap 3 cooperate, so that the outer cap 1 and the connecting part 2 synchronously spiral upward. During this process, the stop block 84 of the decorative part 8 and the gear position 97 of the lower tube 9 cooperate, the decorative part 8 stops rotating, and the decorative part ratchet 82 and the lower tube ratchet 94 cooperate; at the same time, due to the relative rotation between the connecting part 2 and the inner cap 3, the RFID tag is damaged. 2. Continue to rotate the outer cap 1. As the aforementioned connecting part 2 rotates upward relative to the inner cap 3, the rotating boss 12 of the outer cap 1 has disengaged from the rotating groove 81 of the decorative part 8. When the connecting part 2 rotates the lifting window 26 to the hook 32 of the inner cap 3, the outer pushing boss 27 of the connecting part 2 pushes the hook 32 of the inner cap 3 outward to deform it, and the hook 32 disengages from the bottle mouth stop 51. At this time, the hook 32 of the inner cap 3 abuts against the connecting part 2, and there is no relative rotation between the inner cap 3 and the connecting part 2, and the inner cap ratchet 31 and the connecting part ratchet 21 cooperate. 3. Continue to rotate the outer cap 1. At this time, the inner cap 3, the connecting part 2 and the outer cap 1 rotate synchronously. The anti-return ring 34 of the inner cap 3 deforms and slides out from the upper end of the lower tube 9, the lower tube stop ring 99. Continue to rotate the outer cap 1 until it is unscrewed.

[0100] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
