Description

Technical Field

[0001] The invention belongs to the technical field of bottle caps, and in particular relates to an anti-counterfeiting bottle cap. Background Art

[0002] Most of the bottle caps that destroy caps and bottles used now are anti-counterfeiting tooth-type cap-destroying bottle-destroying plastic caps, which are composed of a toothed plastic outer cap, an inner cap, an inner plug and a bottle opener. The inner plug is separate from the toothed plastic outer cap. When filling, first assemble the inner cap and the inner plug and then press them onto the bottle mouth, then press the toothed plastic outer cap onto the bottle mouth, and finally hang the bottle opener on the bottle mouth.

[0003] The utility model patent with patent application number CN201320712695.7 discloses a liquor bottle cap. The anti-counterfeiting sleeve is divided into an anti-counterfeiting upper shell and an anti-counterfeiting lower shell. The anti-counterfeiting lower shell is a round tube sleeve, which is sleeved on the bottle cap seat and fixedly connected to the bottle cap seat. A baffle protrudes inwardly on the anti-counterfeiting lower shell, and the edge of the bottle cap protrudes outwardly to fit the baffle with a card. The card and the baffle cooperate to form a limiting structure. The baffle supports the card, and the bottle cap is pressed against the anti-counterfeiting lower shell. The bottle cap is linked to the rotating handle. The above structure arranges an anti-counterfeiting sleeve on the bottle cap seat, and adopts a limiting structure of a card and a blocking piece. When the liquor bottle cap is opened, the rotating handle drives the bottle cap to be forcibly pulled up, thereby destroying the limiting structure. When the bottle cap is closed again, the limiting structure cannot be restored. After the limiting structure is destroyed, the bottle cap is closed again, and the card is located between the anti-counterfeiting upper shell and the anti-counterfeiting lower shell. There will be a gap between the anti-counterfeiting upper shell and the anti-counterfeiting lower shell, which can be directly observed with the naked eye, forming an obvious anti-counterfeiting feature, and the anti-counterfeiting effect is obvious.

[0004] However, the bottle plug of the bottle cap is not provided with a hanging platform, and the connection between the bottle plug and the container mouth is unreliable. When the outer cover is pulled out, the bottle plug is easy to come out of the container mouth. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the present invention aims to provide an anti-counterfeiting bottle cap with reliable connection.

[0006] The technical solution adopted by the present invention is:

[0007] An anti-counterfeiting bottle cap comprises an inner plug for inserting into the mouth of a container, wherein the inner plug is provided with a bottle mouth structure, the lower end of the bottle mouth structure is provided with a bottle mouth hook, the lower end of the inner plug is provided with a plurality of hanging platforms, and the bottle mouth hooks are engaged with the hanging platforms; the upper end of the inner plug is provided with a positioning ring, a positioning step is provided in the mouth of the container, the positioning ring is overlapped on the positioning step, the upper end of the bottle mouth structure is provided with an anti-drop ring, and the anti-drop ring is overlapped on the positioning ring; the bottle mouth structure is internally threadedly connected with an inner cover, and an anti-counterfeiting outer cover is sleeved on the inner cover, and the anti-counterfeiting outer cover is connected to the bottle mouth structure. The positioning ring is overlapped on the positioning step, and the anti-drop ring is overlapped on the positioning ring, so that the upper ends of the inner plug and the bottle mouth structure are limited, and the inner plug and the bottle mouth structure will not be pressed into the bottle. A card slot is provided on the hanging platform of the inner plug, and when the bottle mouth structure is installed, the bottle mouth hook of the bottle mouth structure is engaged with the card slot on the hanging platform, so that the bottle mouth structure can no longer move to the outside of the bottle, and the lower end of the bottle mouth structure is limited. When the bottle mouth hook is engaged with the hanging platform, the hanging platform is pushed open at a certain angle, and the outer side of the hanging platform extends beyond the neck section of the container mouth, and the hanging platform cannot enter the neck section, so the lower end of the inner plug is limited. Since the upper and lower ends of the inner plug and the bottle mouth structure are limited, the inner plug and the bottle mouth structure are reliably connected to the container mouth and will not fall out or be pressed into the container mouth.

[0008] As a preferred solution of the present invention, a plurality of sealing rings are arranged on the annular surface of the inner plug, and the sealing rings can be closely attached to the inner wall of the container mouth to prevent liquid from leaking therefrom.

[0009] As a preferred embodiment of the present invention, the anti-counterfeiting outer cover includes a collar, an outer cover hook is arranged inside the collar, a bottle mouth buckle ring is arranged at the upper end of the bottle mouth structure, the bottle mouth buckle ring is buckled with the outer cover hook, and a cover body is connected to the collar through a plurality of connecting rods, and the cover body is sleeved on the inner cover. Since the bottle mouth buckle ring is buckled with the outer cover hook on the collar, the collar cannot be removed. When the cover body is pulled out or screwed, the connecting rod is disconnected from the cover body, and the cover body can be opened. Since the cover body cannot be connected to the connecting rod after being taken out, the anti-counterfeiting outer cover plays an anti-counterfeiting role to prevent artificial adulteration in the bottle.

[0010] As a preferred embodiment of the present invention, the top surface of the bottle mouth structure is lower than the top surface of the collar, and a splash-proof step is provided inside the container mouth, and the top surface of the splash-proof step is not lower than the top surface of the collar. When pouring out the liquid, the liquid flows from the top surface of the bottle mouth structure to the surface of the collar, and then flows to the splash-proof step of the container mouth and then flows out from the outer edge of the container mouth. Since the top surface of the bottle mouth structure is lower than the top surface of the collar, and the top surface of the splash-proof step is not lower than the top surface of the collar, the liquid always flows along the inner wall of each structure, and the liquid will not be directly poured out from the end of the bottle mouth structure, thereby avoiding liquid splashing. For a container mouth with a pointed mouth, the liquid flows out from the pointed mouth along the inner wall of the container mouth, avoiding liquid splashing.

[0011] As a preferred solution of the present invention, the positioning ring of the inner plug is provided with an inner plug anti-rotation rib, the outer wall of the collar is provided with a collar anti-rotation rib, and the inner plug anti-rotation rib and the collar anti-rotation rib are meshed. The inner plug anti-rotation rib can prevent the collar from rotating, so when the cover body is taken out, the cover body can be separated from the connecting rod more easily, which is convenient for operation.

[0012] As a preferred embodiment of the present invention, an opening is provided on the annular surface of the bottle mouth structure, and the upper edge of the opening is higher than the lower edge of the neck section of the container mouth. When the liquid in the bottle is small, the liquid can flow from the opening into the bottle mouth structure. Since the upper edge of the opening is higher than the lower edge of the neck section of the container mouth, the liquid can flow completely into the bottle mouth structure, avoiding liquid residue in the bottle.

[0013] As a preferred solution of the present invention, a flow limiting ring is connected inside the bottle mouth structure, and a plurality of flow limiting holes are provided between the edge of the flow limiting ring and the inner wall of the bottle mouth structure. When the liquid flows into the bottle mouth structure, it can only flow through the flow limiting holes, thereby avoiding the situation where the liquid flow is too large. Moreover, the flow limiting holes are located between the inner wall of the bottle mouth structure and the edge of the flow limiting ring, so that the liquid always flows along the inner wall of the bottle mouth structure, further reducing the situation where the liquid splashes.

[0014] As a preferred embodiment of the present invention, a sealing inner step is provided inside the inner plug, a sealing outer step is provided on the annular surface of the bottle mouth structure, and the sealing outer step overlaps the sealing inner step; a sealing concave surface is provided inside the bottle mouth structure, and a sealing convex surface is provided on the outer wall of the inner cover, and the sealing concave surface is in close contact with the sealing convex surface. Since the sealing outer step overlaps the sealing inner step, the inner plug and the bottle mouth structure can be reliably sealed. Since the sealing concave surface is in close contact with the sealing convex surface, the bottle mouth structure and the inner cover can be reliably sealed, thereby preventing liquid from leaking out after tightening the inner cover.

[0015] As a preferred solution of the present invention, the positioning ring of the inner plug is provided with an inner plug outer anti-rotation rib, the container mouth is provided with a container mouth anti-rotation rib, and the inner plug outer anti-rotation rib is meshed with the container mouth anti-rotation rib. The container mouth anti-rotation rib can prevent the inner plug from rotating, so that the inner plug can be stably connected to the bottle, and the inner plug and the container mouth are prevented from loosening.

[0016] As a preferred embodiment of the present invention, the inner cover is provided with an inner cover anti-rotation rib, and the outer cover anti-rotation rib is provided inside the anti-counterfeiting outer cover, and the inner cover anti-rotation rib and the outer cover anti-rotation rib are engaged with each other. The inner cover anti-rotation rib can prevent the anti-counterfeiting outer cover from rotating, so when the anti-counterfeiting outer cover is screwed, not only the anti-counterfeiting outer cover can be removed, but also the inner cover can be loosened, so that it is convenient to screw the inner cover after taking out the anti-counterfeiting outer cover.

[0017] As a preferred embodiment of the present invention, it also includes dustproof paper, which is pasted on the upper end of the container mouth, and the upper surface of the dustproof paper or the upper top surface of the anti-counterfeiting outer cover is provided with an external information code, and the lower surface of the dustproof paper or the inner top surface of the anti-counterfeiting outer cover or the upper top surface of the inner cover is provided with an internal information code. The dustproof paper can prevent dust from intruding, and the external information code and the internal information code can facilitate users to query anti-counterfeiting information.

[0018] As a preferred solution of the present invention, the inner cover comprises an inner cover body and a cover sheet, a card slot is provided in the cover body, a cover sheet hook is provided on the cover sheet, and the cover sheet hook engages with the card slot. When connecting the inner cover body and the cover sheet, the cover sheet only needs to be pressed into the inner cover body, and the cover sheet hook on the cover sheet can engage with the card slot on the inner cover body to achieve a reliable connection.

[0019] The beneficial effects of the present invention are:

[0020] 1. The positioning ring of the present invention is overlapped on the positioning step, and the anti-drop ring is overlapped on the positioning ring, so that the upper ends of the inner plug and the bottle mouth structure are limited, and the inner plug and the bottle mouth structure will not be pressed into the bottle. A card slot is provided on the hanging platform of the inner plug. When the bottle mouth structure is installed, the bottle mouth hook of the bottle mouth structure is engaged with the card slot on the hanging platform, so that the bottle mouth structure can no longer move to the outside of the bottle, and the lower end of the bottle mouth structure is limited. When the bottle mouth hook is engaged with the hanging platform, the hanging platform is squeezed open at a certain angle, and the outer side of the hanging platform extends out of the neck section of the container mouth, and the hanging platform cannot enter the neck section, so the lower end of the inner plug is limited. Since the upper and lower ends of the inner plug and the bottle mouth structure are limited, the inner plug and the bottle mouth structure are reliably connected to the container mouth and will not fall out or be pressed into the container mouth. The inner cover is threadedly connected to the bottle mouth structure, and the anti-counterfeiting outer cover is connected to the bottle mouth structure, so that the inner cover and the outer cover can be reliably connected.

[0021] 2. Since the bottle mouth buckle ring is engaged with the outer cover hook on the collar, the collar cannot be removed. When the cover is pulled out or twisted, the connecting rod is disconnected from the cover and the cover can be opened. Since the cover cannot be connected to the connecting rod after being removed, the anti-counterfeiting outer cover plays an anti-counterfeiting role to prevent artificial adulteration in the bottle.

[0022] 3. Since the top surface of the bottle mouth structure is lower than the top surface of the collar, and the top surface of the splash-proof step is not lower than the top surface of the collar, the liquid always flows along the inner walls of each structure, and the liquid will not be poured directly from the end of the bottle mouth structure, thereby avoiding liquid splashing.

DETAILED DESCRIPTION

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figure 1 to Figure 3As shown, the anti-counterfeiting bottle cap of the present embodiment is used for a liquor bottle, and comprises an inner plug 2 for being inserted into the container mouth 1 of the liquor bottle, the inner plug 2 being provided with a bottle mouth structure 3, the lower end of the bottle mouth structure 3 being provided with a bottle mouth hook 31, the lower end of the inner plug 2 being provided with a plurality of hanging platforms 21, the bottle mouth hooks 31 being engaged with the hanging platforms 21; a positioning ring 22 is provided at the upper end of the inner plug 2, a positioning step 11 is provided in the container mouth 1, the positioning ring 22 is overlapped on the positioning step 11, an anti-drop ring 32 is provided at the upper end of the bottle mouth structure 3, the anti-drop ring 32 is overlapped on the positioning ring 22; the bottle mouth structure 3 is internally threadedly connected with an inner cover 4, the inner cover 4 is provided with an anti-counterfeiting outer cover 5, and the anti-counterfeiting outer cover 5 is connected to the bottle mouth structure 3.

[0037] like Figure 6 As shown, the mouth of the container 1 is provided with a neck section. To make the present invention reliably connected to the mouth of the container 1, the present invention must be limited on both the upper and lower sides of the neck section. The positioning ring 22 overlaps the positioning step 11, and the anti-drop ring 32 overlaps the positioning ring 22, so that the upper ends of the inner plug 2 and the bottle mouth structure 3 are limited, and the inner plug 2 and the bottle mouth structure 3 will not be pressed into the bottle. A card slot 431 is provided on the hanging platform 21 of the inner plug 2. When the bottle mouth structure 3 is installed, the bottle mouth hook 31 of the bottle mouth structure 3 is engaged with the card slot 431 on the hanging platform 21, so that the bottle mouth structure 3 can no longer move to the outside of the bottle, and the lower end of the bottle mouth structure 3 is limited. When the bottle mouth hook 31 is engaged with the hanging platform 21, the hanging platform 21 is squeezed open at a certain angle, and the outer side of the hanging platform 21 extends out of the neck section of the mouth of the container 1, and the hanging platform 21 cannot enter the neck section, so the lower end of the inner plug 2 is limited. Since the upper and lower ends of the inner plug 2 and the bottle mouth structure 3 are both limited, the inner plug 2 and the bottle mouth structure 3 are reliably connected to the container mouth 1 and will not fall out or be pressed into the container mouth 1. A plurality of sealing rings 23 are arranged on the annular surface of the inner plug 2, and the sealing rings 23 can be tightly attached to the inner wall of the container mouth 1 to prevent liquid from leaking therefrom.

[0038] When the anti-counterfeit outer cover 5 is removed and the inner cover 4 is selected, the bottle is tilted, and the liquid flows into the bottle mouth structure 3 and then flows out from the inner wall of the bottle mouth structure 3 .

[0039] Specifically, Figure 4 and Figure 7As shown, the anti-counterfeiting outer cover 5 includes a collar 51, an outer cover hook 511 is arranged inside the collar 51, a bottle mouth buckle ring 33 is arranged at the upper end of the bottle mouth structure 3, the bottle mouth buckle ring 33 is buckled with the outer cover hook 511, and a cover body 53 is connected to the collar 51 through a plurality of connecting rods 52, and the cover body 53 is sleeved on the inner cover 4. Since the bottle mouth buckle ring 33 is buckled with the outer cover hook 511 on the collar 51, the collar 51 cannot be taken out. When the cover body 53 is pulled out or screwed, the connecting rod 52 is disconnected from the cover body 53, and the cover body 53 is opened. Since the cover body 53 cannot be connected to the connecting rod 52 after being taken out, the anti-counterfeiting outer cover 5 plays an anti-counterfeiting role to prevent artificial adulteration in the bottle.

[0040] In order to achieve the purpose of splash prevention when pouring liquid, such as Figure 6 , Figure 7 and Fig.11 As shown, the top surface of the bottle mouth structure 3 is lower than the top surface of the collar 51, and a splash-proof step 12 is provided in the container mouth 1, and the top surface of the splash-proof step 12 is not lower than the top surface of the collar 51. When pouring out the liquid, the liquid flows from the top surface of the bottle mouth structure 3 to the surface of the collar 51, and then flows to the splash-proof step 12 of the container mouth 1 and then flows out from the outer edge of the container mouth 1. Since the top surface of the bottle mouth structure 3 is lower than the top surface of the collar 51, and the top surface of the splash-proof step 12 is not lower than the top surface of the collar 51, the liquid always flows along the inner wall of each structure, and the liquid will not be directly poured out from the end of the bottle mouth structure 3, thereby avoiding the liquid from splashing. For the container mouth 1 with a pointed mouth, the liquid flows out from the pointed mouth along the inner wall of the container mouth 1 to avoid the liquid from splashing.

[0041] In order to prevent the cover 53 from rotating, Figure 4 and Figure 5 As shown, the positioning ring 22 of the inner plug 2 is provided with an inner plug anti-rotation rib 24, and the outer wall of the collar 51 is provided with a collar anti-rotation rib 512, and the inner plug anti-rotation rib 24 is engaged with the collar anti-rotation rib 512. The inner plug anti-rotation rib 24 can prevent the collar 51 from rotating, so when the cover body 53 is taken out, the cover body 53 can be more easily separated from the connecting rod 52, which is convenient for operation.

[0042] In order to facilitate the complete pouring of liquid, Figure 7 As shown, an opening 34 is provided on the annular surface of the bottle mouth structure 3, and the upper edge of the opening 34 is higher than the lower edge of the neck section of the container mouth 1. When the liquid in the bottle is small, the liquid can flow from the opening 34 into the bottle mouth structure 3. Since the upper edge of the opening 34 is higher than the lower edge of the neck section of the container mouth 1, the liquid can flow completely into the bottle mouth structure 3, avoiding liquid residue in the bottle.

[0043] Furthermore, Fig. 9As shown, the bottle mouth structure 3 is connected to a limiting flow ring 35, and a plurality of limiting flow holes 351 are provided between the edge of the limiting flow ring 35 and the inner wall of the bottle mouth structure 3. When the liquid flows into the bottle mouth structure 3, it can only flow through the limiting flow holes 351, thereby avoiding the situation where the liquid flow is too large. Moreover, the limiting flow holes 351 are located between the inner wall of the bottle mouth structure 3 and the edge of the limiting flow ring 35, so that the liquid always flows along the inner wall of the bottle mouth structure 3, further reducing the situation where the liquid splashes.

[0044] To ensure sealing, Fig.10 and Fig.11 As shown, the inner plug 2 is provided with a sealing inner step 25, and the annular surface of the bottle mouth structure 3 is provided with a sealing outer step 36, and the sealing outer step 36 overlaps the sealing inner step 25; the bottle mouth structure 3 is provided with a sealing concave surface 37, and the outer wall of the inner cover 4 is provided with a sealing convex surface 42, and the sealing concave surface 37 is in close contact with the sealing convex surface 42. Since the sealing outer step 36 overlaps the sealing inner step 25, the inner plug 2 and the bottle mouth structure 3 can be reliably sealed. Since the sealing concave surface 37 is in close contact with the sealing convex surface 42, the bottle mouth structure 3 and the inner cover 4 can be reliably sealed, and liquid leakage is avoided after the inner cover 4 is tightened.

[0045] Furthermore, Fig.11 As shown, the positioning ring 22 of the inner plug 2 is provided with an inner plug outer anti-rotation rib 26, and the container mouth 1 is provided with a container mouth anti-rotation rib 13, and the inner plug outer anti-rotation rib 26 is engaged with the container mouth anti-rotation rib 13. The container mouth anti-rotation rib 13 can prevent the inner plug 2 from rotating, so that the inner plug 2 can be stably connected to the bottle, and the inner plug 2 and the container mouth 1 can be prevented from loosening.

[0046] Furthermore, Figure 4 and Figure 8 As shown, the inner cover 4 is provided with an inner cover anti-rotation rib 41, and the anti-counterfeit outer cover 5 is provided with an outer cover anti-rotation rib 54, and the inner cover anti-rotation rib 41 and the outer cover anti-rotation rib 54 are engaged. The inner cover anti-rotation rib 41 can prevent the anti-counterfeit outer cover 5 from rotating, so when the anti-counterfeit outer cover 5 is screwed, not only the anti-counterfeit outer cover 5 can be removed, but also the inner cover 4 can be loosened, so that it is convenient to take out the anti-counterfeit outer cover 5 and then screw the inner cover 4.

[0047] Furthermore, it also includes a dustproof paper 6, which is pasted on the upper end of the container mouth 1, and an external information code is provided on the upper surface of the dustproof paper 6 or the upper top surface of the anti-counterfeiting outer cover 5, and an internal information code is provided on the lower surface of the dustproof paper 6 or the inner top surface of the anti-counterfeiting outer cover 5 or the upper top surface of the inner cover 4. The dustproof paper 6 can prevent dust from intruding, and the external information code and the internal information code can facilitate users to query anti-counterfeiting information.

[0048] Furthermore, Figure 8As shown, the inner cover 4 includes an inner cover 4 body and a cover sheet 44, a card slot 431 is provided in the cover body, and a cover sheet 44 hook is provided on the cover sheet 44, and the cover sheet 44 hook is engaged with the card slot 431. When connecting the inner cover 4 body and the cover sheet 44, it is only necessary to press the cover sheet 44 into the inner cover 4 body, and the cover sheet 44 hook on the cover sheet 44 can be engaged with the card slot 431 on the inner cover 4 body to achieve a reliable connection.

[0049] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention.
