[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains; the terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this invention; the terms "including" and "having" and any variations thereof in the specification and claims of this invention and the accompanying drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" and the like in the specification and claims of this invention and the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0025] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-4As shown, an anti-counterfeiting bottle includes a bottle body, an inner cover 3, an outer cover 4 and a limiting structure. The bottle body includes a bottle body 1 and a bottle mouth 2. A non-return pawl 21 is provided on the circumferential side of the bottle mouth 2. The inner cover 3 is screwed on the bottle mouth 2 and covers the bottle mouth 2. A ratchet 31 is provided on the inner side wall of the inner cover 3 along the circumferential direction. The ratchet 31 engages with the non-return pawl 21. A sealing column 5 is provided on the top of the inner cover 3. A plug 51 and a liquid inlet hole 52 connected to the bottle mouth 2 are respectively provided on the top wall of the sealing column 5. The outer cover 4 is buckled on the inner cover 3 and is slidably connected to the inner cover 3. The outer cover 4 The top wall of the outer cover 4 is provided with a liquid outlet 41, and the inner side of the top wall of the outer cover 4 is provided with an annular sealing sleeve 6, which surrounds the liquid outlet 41 and is sleeved on the sealing column 5. The inner side wall of the sealing sleeve 6 and the top wall of the sealing column 5 enclose a sealed cavity 61, which is used to temporarily store the liquid flowing out through the liquid inlet 52 to prevent the liquid from leaking from the gap between the inner cover 3 and the outer cover 4. The limiting structure is provided between the inner cover 3 and the outer cover 4 to prevent the outer cover 4 from separating from the inner cover 3. The outer cover 4 can slide down along the axial direction of the inner cover 3 to seal the plug 51. The liquid outlet 41 can be blocked, or the plug 51 can be detached from the liquid outlet 41 by sliding upward along the axis of the inner cover 3. Under normal circumstances, the plug 51 blocks the liquid outlet 41. When the liquid in the bottle needs to be poured out, the outer cover 4 can be slid upward to drive the plug 51 to detach from the liquid outlet 41, so that the liquid outlet 41 leaks out, and then the bottle body can be tilted. The liquid in the bottle will flow out through the bottle mouth 2, the liquid inlet hole 52, the sealing cavity 61 and the liquid outlet 41 in sequence. When assembling the anti-counterfeiting bottle, the user can screw the inner cover 3 onto the bottle mouth 2 through the thread. As the inner cover 3 moves downward, the ratchet 3 1 will slide along the inclined surface of the anti-return pawl 21 and deform adaptively. After the inner cap 3 is tightened, the ratchet 31 will engage with the anti-return pawl 21, thereby limiting the inner cap 3 from reversing. Cooperating with the restriction of the limiting structure on the outer cap 4, the liquid in the bottle body can only flow out through the liquid outlet 41. Except for violent disassembly that destroys the structure, the bottle mouth 2, the inner cap 3 and the outer cap 4 cannot be separated, thereby hindering the secondary filling by illegal elements, increasing the cost of secondary filling, and playing the effect of suppressing secondary filling, so as to protect the interests of brand and consumers.

[0028] Specifically, the inner cover 3 and the outer cover 4 are both made of plastic.

[0029] In one embodiment, the limiting structure is a convex point, which is provided on the inner wall of the outer cover 4, and a guide groove is provided on the outer wall of the inner cover 3 along its axial direction. The convex point is slidably connected in the guide groove. The user can lift the outer cover 4 to separate the plug 51 from the liquid outlet 41. At this time, the convex point will slide up along the guide groove, and the same applies when sliding down. The sliding stroke of the outer cover 4 is limited by the guide groove to prevent the outer cover 4 from separating from the inner cover 3 (not shown in the drawings).

[0030] Furthermore, the limiting structure includes a slider 7, which is arranged on the inner wall of the outer cover 4. A spiral groove 32 is circumferentially opened on the outer wall of the inner cover 3. The slider 7 is slidably connected in the spiral groove 32. The user can rotate the outer cover 4 to make the slider 7 slide along the spiral groove 32, and use the reaction force of the inner wall of the spiral groove 32 to drive the outer cover 4 to rise or fall axially, thereby controlling the plug 51 to block the liquid outlet 41 or detach from the liquid outlet 41. At the same time, the slider 7 cannot detach from the two ends of the spiral groove 32, and the outer cover 4 can be restricted on the inner cover 3.

[0031] Furthermore, the top of the inner cover 3 is provided with a accommodating chamber 33 which opens upward, and the sealing column 5 is coaxially arranged on the bottom wall of the accommodating chamber 33 and spaced from the side wall of the accommodating chamber 33. The accommodating chamber 33 can retain part of the liquid flowing out from the gap between the sealing sleeve 6 and the sealing column 5, thereby preventing the anti-counterfeiting bottle from leaking, improving the user experience, and at the same time helping to control the overall height of the anti-counterfeiting bottle.

[0032] Furthermore, the plug 51 includes an upper half 511 adapted to the contour of the liquid outlet 41 and a lower half 512 connected to the top wall of the sealing column 5. The longitudinal cross-section of the lower half 512 is trapezoidal. When the outer cover 4 moves downward and the plug 51 gradually extends into the liquid outlet 41, the outer cover 4 will apply a downward force to the upper half 511 through friction resistance. At this time, the frustum-shaped lower half 512 can provide a more stable support force for the upper half 511.

[0033] Furthermore, the plug 51 has a hollow interior structure so that the plug 51 can be deformed to ensure the sealing effect of the plug 51 on the liquid outlet 41 .

[0034] Furthermore, an introduction groove 34 with an upper end passing through is provided on the outer side wall of the inner cover 3 along its axial direction, and an inclined surface 35 is provided at the lower end of the introduction groove 34, which is adjacent to the lower end of the spiral groove 32. When installing the outer cover 4, it is only necessary to align the opening of the outer cover 4 downward with the top of the inner cover 3, and align the slider 7 with the introduction groove 34, and then press down the outer cover 4, put the outer cover 4 on the inner cover 3, and slide the slider 7 into the introduction groove 34. As the outer cover 4 moves downward, the slider 7 will slide to the outer side wall of the inner cover 3 through the inclined surface 35, and finally be clamped at the lower end of the spiral groove 32. During this process, the part of the outer cover 4 where the slider 7 is provided will undergo adaptive deformation.

[0035] Furthermore, a first protrusion 81 is vertically provided on the bottom wall of the lower end of the spiral groove 32, and a first locking position 321 is formed between the first protrusion 81 and the lower end wall of the spiral groove 32. When the outer cover 4 is tightened and the plug 51 blocks the liquid outlet 41, the slider 7 will be locked in the first locking position 321, thereby helping to position the outer cover 4 and prevent the liquid outlet 41 from easily detaching from the plug 51 and causing leakage.

[0036] Furthermore, two second ridges 82 are vertically provided on the middle bottom wall of the spiral groove 32. The two second ridges 82 are spaced apart from each other to form a second locking position 322. When the outer cover 4 rotates and rises, and the plug 51 just breaks away from the liquid outlet 41, the slider 7 will be locked in the second locking position 322, thereby helping to position the outer cover 4 so that the liquid in the bottle can only flow out through the gap between the inner wall of the liquid outlet 41 and the plug 51, making it convenient for the user to slowly pour out the liquid in the bottle.

[0037] Furthermore, a third ridge 83 is vertically provided on the bottom wall of the upper end of the spiral groove 32, and a third locking position 323 is formed between the third ridge 83 and the upper end wall of the spiral groove 32. When the user needs to quickly pour out the liquid in the bottle, the outer cover 4 can be rotated to make the slider 7 engage in the third locking position 323. At this time, the outer cover 4 is positioned and suspended, and the plug 51 is away from the liquid outlet 41. The liquid in the bottle can be directly poured out through the liquid outlet 41 at a faster speed.

[0038] Furthermore, a plurality of liquid inlet holes 52 are provided and distributed along the circumference of the sealing column 5 .
