[0002] For wine, perfume, high-end health care product and other enterprises, the anti-fake of the packaging bottle is very important. If the bottle is not anti-fake enough, for example, the wine bottle, fake wine can be easily made by recycling old wine bottles and wine bottle caps. This makes the market full of low-priced fake wine, which impacts the real wine market and causes great damage to the reputation of wine production enterprises, affecting the development of enterprises. At the same time, after people drink fake wine, it can cause great damage to their health, especially fake baijiu mixed with industrial alcohol, which can also cause life-threatening. However, the existing wine bottle cap cannot avoid this problem, and the anti-fake effect is relatively poor.

[0003] A patent with the patent publication number CN112550936B discloses an opening self-damage type anti-fake bottle cap and a bottle with the bottle cap. The bottle cap includes an outer cap, an inner sleeve, a pull rope, an outer sleeve assembly, an inner cap assembly, and an inner plug assembly. The outer cap is sleeved on the top end of the inner cap, and a bottom end is left with a falling gap from the inner sleeve. The top end of the inner sleeve is provided with at least one pry hole in communication with the falling gap. The inner sleeve has a shielding piece and a plurality of contact bridges. The shielding piece is arranged in the pry hole and is fixed with the inner sleeve through the plurality of contact bridges. One end of each pull rope is fixed on the corresponding shielding piece, and the other end is fixed on the outer cap. The outer sleeve assembly includes an outer sleeve and at least one set of insertion strips. The inner cap assembly includes an upper cap body, a lower connecting sleeve, and a limiting structure. The inner plug assembly includes an upper inner plug, a lower inner plug, and a sealing film. The permanent damage marks of the inner and outer layers of the bottle cap also completely damage the bottle. The bottle and the bottle cap cannot be used again, thereby improving the anti-fake effect of the bottle cap.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative labor based on the embodiments in the present application belong to the scope of protection of the present application.

[0039] EMBODIMENT

[0040] As Figures 1-2 shown, a sealing anti-fake device includes a bottle mouth 1, an inner plug 2, a check valve 3, a bottle cap assembly, etc. The bottle mouth 1 is integrally manufactured with a bottle body (not shown in the figure).

[0041] As Figure 2As shown in the bottle mouth 1 upper end inner wall is provided with a tapered limiting hole 12; the inner plug 2 outer wall shape and tapered limiting hole 12 consistent, inserted in the tapered limiting hole 12. Inner plug 2 as a kind of sealing assembly, plays a sealing role. Inner plug 2 hollow inside, inner plug 2 bottom end extends inwardly has tapered sealing portion 21, and the sealing ball 5 is arranged on the sealing portion 21, when the bottle is placed horizontally, the sealing ball 5 blocks the sealing portion 21 to achieve the sealing effect; inner plug 2 middle part extends inwardly and is provided with a tapered drainage portion 22. The opening of the sealing portion 21 is used for wine to flow out, when pouring wine, the sealing ball 5 leaves the sealing portion 21, the wine in the bottle enters the inner cavity of the inner plug 2 through the bottle mouth 1, the sealing portion 21, and then flows out of the inner plug 2 through the opening of the drainage portion 22.

[0042] As shown in Figure 2 The check valve 3 is circumferentially distributed with a plurality of elastic connecting pieces, and the elastic connecting pieces are fixed on the drainage portion 22; the check valve 3 is provided with an arc-shaped limiting portion 31 at the bottom end, and the limiting portion 31 can be connected with the sealing ball 5 in cooperation when being pressed. As shown in Figure 2 At this time, the check valve 3 is subjected to a downward pressing force, the elastic connecting pieces are deformed, the limiting portion 31 is arranged in close contact with the upper end of the sealing ball 5, and the lower end of the sealing ball 5 is arranged in close contact with the sealing portion 21, so that the sealing ring can be closely attached to the sealing portion 21, the sealing property of the bottle packaging is ensured, and the wine is prevented from overflowing from the bottle mouth 1 to the inside of the bottle cap assembly.

[0043] The check valve 3 is hollow inside, and a gas bag 4 is arranged in the inner cavity; the sealing ball 5 is provided with a gas bag 6; a gas needle assembly is slidably arranged on the inner wall of the limiting portion 31, one end of the gas needle assembly is inserted into the gas bag 1, and the other end of the gas needle assembly is inserted into the gas bag 2, for connecting the gas bag 1 and the gas bag 2. In the present application, the gas bag 1 serves as an inflating device, and a certain pressure gas is previously filled in the gas bag 1; the gas bag 2 is not initially inflated, and only when the gas bag 1 and the gas bag 2 are connected through the gas needle assembly, the gas bag 2 is inflated through the gas bag 1. The reason why the present application is designed in this way is that, in actual scenarios, since the gas bag 2 is arranged in the sealing ball 5, when the sealing ball 5 and the gas bag 2 are all located in the inner plug 2, it is difficult to inflate the gas bag 2 through the inflating device, therefore, the gas bag 1 is arranged at the bottom end of the check valve 3 to serve as an inflating device, to achieve the packaging and the inflation of the gas bag 2 through the gas bag 1 at the same time, and to achieve the arrangement of the anti-fake structure.

[0044] As shown in Figure 2As shown, the bottle cap assembly is arranged on the outer wall of the bottle mouth 1, and the bottle cap assembly is arranged closely to the check valve 3 inside, so that the limiting part 31 and the sealing ball 5, the sealing ball 5 and the sealing part 21 are tightly sealed. When packaging, the sealing ball 5 needs to be adjusted to the front of the inflation joint 61 of the air bag two 6, that is, the air bag one 4 and the air bag two 6 are arranged opposite to each other. Then the packaging is carried out. When packaging, the bottle cap assembly is fixed on the outer wall of the bottle mouth 1, and the bottle cap assembly acts on the check valve 3, providing a downward pressing force for the check valve 3, thereby driving the check valve 3 to press downward, so that the limiting part 31 tightly seals the sealing ball 5. At the same time, the upper end of the air needle assembly on the limiting part 31 is inserted into the air bag one 4, and the lower end is inserted into the air bag two 6, thereby connecting the air bag one 4 and the air bag two 6, and filling the gas in the air bag one 4 into the air bag two 6 until reaching the equilibrium state. After the bottle is packaged, the air bag one 4 and the air bag two 6 are connected, the anti-fake structure is arranged, the bottle cap assembly is arranged on the outer wall of the bottle mouth 1, and the bottle cap assembly is arranged closely to the check valve 3 inside, so that the limiting part 31 and the sealing ball 5, the sealing ball 5 and the sealing part 21 are tightly sealed, preventing the sealing ball 5 from moving during transportation to reduce the sealing performance.

[0045] When the bottle cap assembly is disassembled, the pressure of the bottle cap assembly on the check valve 3 is removed, the check valve 3 is reset, the air needle assembly is separated from the air bag two 6, the limiting part 31 is separated from the sealing ball 5, the air bag one 4 and the air bag two 6 are exhausted, and the sealing ball 5 is freely rotated and moved, and the relative exhaust of the air bag one 4 and the air bag two 6 can quickly drive the sealing ball 5 to rotate until the gas in the air bag one 4 and the air bag two 6 is exhausted. When pouring wine, the bottle is poured and placed, the sealing ball 5 is separated from the sealing part 21 and falls on the limiting part 31, and the wine can flow out of the opening of the sealing part 21.

[0046] In the present application, when the bottle cap assembly is disassembled, the connection state of the air bag one 4 and the air bag two 6 is destroyed, at the same time, the air bag one 4 and the air bag two 6 are exhausted and act on the sealing ball 5, so that the sealing ball 5 is freely rotated and moved, and the abutting point is moved away, it is difficult for counterfeiters to detect the existence of the air bag inside the sealing ball 5, so that the air bag one 4 and the air bag two 6 cannot be connected again, that is, it cannot be restored to the initial state; and since the anti-fake structure of the present application is arranged in the sealing ball 5, the sealing ball 5 is used for sealing the bottle mouth 1 and is located in the innermost side, normal anti-fake personnel will not disassemble the sealing ball 5 for checking, and once the sealing ball 5 is disassembled, the entire bottle mouth 1 and inner plug 2 will be damaged, which is difficult to counterfeit and has good anti-fake effect; at the same time, the check valve 3 is arranged in the inner plug 2, the air bag one 4 is arranged in the check valve 3, the air bag one 4 and the air bag two 6 are connected during packaging, the air bag one 4 is used as an inflation device, the overall structure is ingenious, and the anti-fake structure is easy to start and use.

[0047] As Figures 3-6As shown, the present application further optimizes the design of the air needle assembly, specifically: the air needle assembly comprises a shell one 41, a plug 43, a piston 44 and a puncture part 45, the middle of the limiting part 31 is provided with a mounting hole 311, the shell one 41 is arranged in the mounting hole 311, the plug 43, the piston 44 and the puncture part 45 are integrally connected and internally through arranged; the piston 44 is slidingly arranged in the inner cavity of the shell one 41, a spring one 46 is sleeved between the piston 44 and the inner wall of the shell one 41, and the spring one 46 is sleeved on the outer periphery of the puncture part 45; one end of the shell one 41 is provided with a plug hole one 42, the tip of the puncture part 45 is opposite to the plug hole one 42 and the inflation port (not shown in the figure) of the air bag one 4; the sealing ball 5 is provided with a shell two 51, the air connector 61 of the air bag two 6 is arranged on the inner wall of the shell two 51, and the end face of the shell two 51 is provided with a plug hole two 52. When the limiting part 31 is pressed to tightly contact the sealing ball 5, the plug 43 is inserted through the plug hole two 52 and the air connector 61, after the plug 43 and the air connector 61 are fixed, when the limiting part 31 continues to be pressed, the puncture part 45 is driven to move upwards and is inserted into the inflation port of the air bag one 4 through the plug hole one 42, so that the gas in the air bag one 4 is discharged into the air bag two 6. Such design can drive the sealing ball 5 to press the sealing part 21 tightly when the bottle is packaged and the cap is screwed, and simultaneously connect the air bag one 4 and the air bag two 6, so as to realize the inflation operation of the air bag two 6.

[0048] As Figure 6 shown, further, the air connector 61 is provided with a conical valve port 62, the conical valve port 62 is provided with a valve ball 65, the valve ball 65 is connected to the filter plate 63 on the inner wall of the air connector 61 through a spring two 64; the bottom end of the plug 43 is provided with a notch, the notch is provided with a magnet 432, and the bottom end of the magnet 432 is provided with a spherical recess corresponding to the valve ball 65. When the plug 43 is inserted to reach the conical valve ball 65 and is inserted in place, the plug 43 and the air connector 61 are connected, the valve ball 65 is adsorbed to the bottom surface of the magnet 432, and the valve ball 65 opens the air connector 61. Then, when the limiting part 31 continues to move downwards, the bottom end of the plug 43 abuts against the conical valve port 62, so as to drive the puncture part 45 to move upwards and be inserted into the inflation port of the air bag one 4, thereby connecting the air bag one 4 and the air bag two 6. Such design can open the air bag two 6 first and then open the air bag one 4 when the bottle is packaged, and the two are connected to be inflated, which is ingenious and easy to realize.

[0049] As Figure 6 shown, the puncture part 45 is provided with an air hole one 461, and the plug 43 is uniformly provided with a plurality of air holes two 431 connected with the air hole one 461. After the puncture part 45 is inserted into the air bag one 4, the gas in the air bag one 4 reaches the inner cavity of the air connector 61 through the air hole one 461 and the air hole two 431, and finally reaches the air bag two 6.

[0050] The above-mentioned structure design can not only link the check valve 3 to move when sealing the bottle cap assembly, so that the sealing ball 5 can be pressed and sealed, but also drive the air needle assembly to move and connect the air bag 4 and the air bag 6. At the same time, it can ensure sufficient sealing and prevent the wine from entering the air bag 6 when pouring.

[0051] This invention further optimizes the design of the bottle cap assembly, which includes an outer cap 9, an inner cap 8, an outer sleeve 10, and a spout 7. Specifically:

[0052] like Figure 3 , 7 As shown, the check valve 3 is cylindrical with a hollow interior, separated by a partition 32, forming a lower air bladder cavity 36 and an upper opening insertion hole 35. The air bladder cavity 36 has a mounting hole 311 at its bottom. The elastic connector includes an elastic strip 33 and a snap-fit ​​part 34, with the elastic strip 33 fixed to the outer wall of the check valve 3. The inner plug 2 and the drainage part 22 form an annular flow-gathering cavity 221, with at least one drainage hole 25 at its bottom. When the check valve 3 is not pressurized, the elastic strip 33 does not deform, the limiting part 31 and the sealing ball 5 are at a certain distance, and the sealing ball 5 seals the sealing part 21 by its own weight. The sealing ball 5 is always positioned between the limiting part 31 and the sealing part 21. When installing the sealing ball 5, first place the sealing ball 5 into the inner plug 2, and then weld the annular drainage part 22 onto the inner wall of the inner plug 2. In this case, since the opening of the drainage part 22 is smaller than the sealing ball 5, the sealing ball 5 cannot be removed from the opening of the drainage part 22. Then install the check valve 3, and place the snap-fit ​​part 34 inside the flow-gathering cavity 221 and snap it onto the drainage part 22. Note: When not sealed, airbag 4 and airbag 6 are not connected. Therefore, the sealing ball 5 needs to be placed upright so that the air connector 61 of airbag 6 is facing upwards and directly opposite the air needle assembly. This ensures that when the check valve 3 is pressed down during sealing, the air needle assembly can be inserted into the air connector 61 of airbag 6, thus connecting airbag 4 and airbag 6.

[0053] like Figure 9 As shown, the spout 7 includes an external thread 77 on its outer wall, a tapered crimping hole 71 at the bottom end of the spout 7, a pressure ring 711 on the outer wall at the bottom end of the spout 7, and a pressing groove 712 at the bottom end of the pressure ring 711; the inner wall of the spout 7 has a first annular platform 75 and a second annular platform 72, a first hole 751 in the middle of the first annular platform 75, a second hole 721 in the middle of the second annular platform 72, and a hollow cavity 74 between the first hole 751 and the second hole 721; an annular cavity 76 is provided on the outer side of the first annular platform 75; a plurality of spout holes 73 are provided on the inner circumference of the spout 7, and the bottom end of the second annular platform 72 is set as an arc-shaped inclined surface, which smoothly transitions with the spout holes 73.

[0054] likeFigure 10 As shown in the drawings, the inner wall of the inner cover 8 is provided with internal threads, and the outer wall of the inner cover 8 is provided with two anti-disengagement grooves 81, which are arranged only on part of the outer wall of the inner cover 8; the bottom end of the inner cover 8 is provided with an anti-disengagement boss 82; the inner wall of the inner cover 8 is provided with an annular cover 83; the middle of the inner cover 8 is provided with a mandrel 84; and the top end of the inner cover 8 is provided with an anti-fake two-dimensional code layer 85.

[0055] As shown in the drawings, Figure 11 the inner wall of the outer cover 9 is provided with a protruding tooth 92 that is matched with the anti-disengagement groove 81 for clamping; the bottom end of the outer cover 9 is provided with a buckle type anti-fake tooth 91; the bottom end of the outer cover 9 is provided with a limiting ring groove 93 that is matched with the anti-disengagement boss 82 for connection; and the top end of the outer cover 9 is provided with a transparent layer 94 that can be made of transparent resin, glass or other materials and is fused to the outer cover 9.

[0056] As shown in the drawings, Figures 1-3 the outer wall of the inner plug 2 is provided with a ring 23, which is arranged on the end face of the bottle mouth 1, and the upper end of the inner plug 2 is a ring-shaped sealing part 24; the inner wall of the wine flow nozzle 7 is arranged close to the outer wall of the ring-shaped sealing part 24, the bottom end of the wine flow nozzle 7 is provided with a ring 711, which is arranged close to the ring 23; the outer sleeve 10 is threadedly connected to the outer threads 13 of the bottle mouth 1, the bottom end of the outer sleeve 10 is fused with the third ring 11 to become an integral part, and the inner wall of the upper end of the outer sleeve 10 is provided with a ring 102, which is arranged close to the ring 711; the inner cover 8 and the wine flow nozzle 7 are threadedly connected. With such a design, when the inner plug 2 is inserted into the inner wall of the bottle mouth 1, it is sequentially compressed and sealed by the wine flow nozzle 7, the inner cover 8 and the outer sleeve 10, thereby ensuring the sealing of the entire bottle cap assembly, and the inner plug 2 plays the role of a sealing assembly.

[0057] As shown in the drawings, Figures 1-3 when the bottle cap assembly is packaged, the middle of the wine flow nozzle 7 is provided with a hollow first ring 75 and a second ring 72, and the circumference of the wine flow nozzle 7 is evenly distributed with a plurality of wine flow holes 73; the bottom end of the inner cover 8 is provided with a mandrel 84 that extends in the center, and when the inner cover 8 is screwed onto the wine flow nozzle 7, the mandrel 84 sequentially passes through the inner holes of the first ring 75 and the second ring 72 and is inserted into the insertion hole 35 of the check valve 3 to be arranged close to the upper end face of the partition plate 32. That is, by inserting the mandrel 84 into the insertion hole 35, the check valve 3 is compressed, so that the limiting part 31 is arranged close to the sealing ball 5, and the air needle assembly is inserted into the air bag 1 and the air bag 2, thereby realizing the communication between the air bag 1 and the air bag 2.

[0058] As shown in the drawings, Figure 2As shown, an outer cover 9 is provided outside the inner cover 8. The protruding teeth 92 of the outer cover 9 are located in the anti-detachment groove 81 of the inner cover 8. The limiting ring groove 93 of the outer cover 9 presses against the anti-detachment protrusion 82 of the inner cover 8, thereby preventing the outer cover 9 from being pulled off. At the same time, an anti-counterfeiting tooth 91 is provided at the bottom of the outer cover 9. The anti-counterfeiting tooth 91 is located in the slot 101 of the outer cover 10. When the outer cover 9 is removed, rotating the outer cover 9 will break off the anti-counterfeiting tooth 91, which will fall into the slot 101 and be collected. When the protruding teeth 92 rotate to the edge of the anti-detachment groove 81, they can drive the inner cover 8 to rotate together, thereby opening the inner cover 8.

[0059] In this invention, the inner wall of the first ring platform 75 is tightly attached to the mandrel 84 to achieve a seal; the inner wall of the second ring platform 72 is tightly attached to the outer wall of the check valve 3 to achieve a seal.

[0060] In this invention, the inner wall of the inner cover 8 is provided with an annular baffle 83 for sealing the wine flow hole 73. That is, when the cover is closed, the annular baffle 83 seals the wine flow hole 73 to ensure airtightness.

[0061] In this invention, the bottom end of the drainage part 22 is provided with a plurality of drainage holes 25. When the wine is poured, some of the wine will flow back and gather in the flow-gathering cavity 221, and then enter the inner cavity of the annular sealing part 21 at the bottom end of the inner stopper 2 through the drainage holes 25 to ensure the sealing performance. At the same time, it is convenient to pour out the wine together with the wine in the bottle when pouring the next time.

[0062] In this invention, a transparent layer 94 is provided at the top of the outer cover 9, through which the QR code anti-counterfeiting layer 85 on the end face of the inner cover 8 can be seen.

[0063] Operating principle:

[0064] S1, as Figure 2 As shown, during the encapsulation process, the check valve 3 is pressed down, and the limiting part 31 presses against the sealing ball 5, which in turn presses against the sealing part 21 to achieve a seal. Simultaneously, the air needle assembly connects airbag 4 and airbag 6, with airbag 4 inflating airbag 6. After encapsulation, both airbag 4 and airbag 6 are filled with gas, achieving a balanced state.

[0065] S2, during disassembly, the outer cover 9 and the inner cover 8 are removed. Because the spindle 84 releases pressure on the check valve 3, the check valve 3 elastically resets, causing the air needle assembly to move away from the airbag 6 (e.g., Figure 3When the plug 43 is away from the air joint 61, the air bag one 4 and the air bag two 6 are both deflated, and when the air bag two 6 is deflated, the sealing ball 5 is driven to rotate freely, and the deflation of the air bag one 4 on the surface of the sealing ball 5 also intensifies the disorderly and free rotation of the sealing ball 5 until the deflation is completed. After the connection state of the air bag one 4 and the air bag two 6 is destroyed, it is difficult to restore, and the anti-fake effect is good. Moreover, when the air needle assembly is away from the air joint 61 (i.e. the plug 43 is away from the air joint 61), the valve ball 65 and the magnet 432 are away from each other, the air bag two 6 is outwardly deflated, can push open the valve ball 65 to deflate, until the pressure is insufficient to push open the valve ball 65, and the valve ball 65 closes the air joint 61; when the wine is poured, since the valve ball 65 closes the air joint 61, the function of the one-way valve is realized, so that the wine liquid cannot enter the inner cavity of the air bag two 6 through the air joint 61, and the sealing property is ensured.

[0066] In summary, the sealing anti-fake device can ensure the sealing effect of the internal anti-fake device and greatly improve the anti-fake effect, and has high practicability.

[0067] The preferred embodiments of the present application have been described above, but the present application is not limited to the above, and various modifications and changes can be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
