Description

Technical Field

[0001] The utility model relates to the technical field of container covers, in particular to an anti-counterfeiting bottle cover and an upper cover assembly thereof. Background Art

[0002] A wine bottle is usually composed of a bottle body and an anti-counterfeiting bottle cap, and generally, the wine is first filled into the bottle body, and then the anti-counterfeiting bottle cap is encapsulated on the bottleneck of the bottle body. Existing anti-counterfeiting bottle caps usually include a fixing component fixed on the bottleneck, a twistable upper cover component, and an anti-counterfeiting structure arranged between the fixing component and the upper cover component. When opened for use, the anti-counterfeiting structure is damaged and cannot be repaired, thereby achieving the purpose of anti-counterfeiting by destroying the bottle cap. However, since the upper cover component must meet both strength requirements and sealing requirements with the fixing component, the upper cover component is generally composed of an outer cover and an inner cover located inside the outer cover. The outer cover is generally made of hard material (such as metal or hard plastic), while the inner cover is generally made of soft material (such as PE material), and the outer cover and the outer cover are connected by a buckle. When the upper cover assembly of this structure is heated by a hair dryer or hot water, the convex structure between the inner cover and the outer cover may fail, and the fixing assembly may be easily removed. In this way, criminals can achieve the purpose of counterfeiting by recycling bottles and anti-counterfeiting bottle caps, so the anti-counterfeiting effect is not ideal.

[0003] In order to solve the above problems, Chinese patent CN219822289U discloses an anti-counterfeiting bottle cap that can be used twice, which improves the inner cover design of the bottle cap. Figure 1 The inner cap comprises an inner cylinder 1a and an inner sealing plate 1b. The inner cylinder 1a is made of hard plastic, while the inner sealing plate 1b is made of soft plastic. This design not only meets sealing requirements but also improves the connection strength between the inner and outer caps. However, in actual use, this anti-counterfeiting bottle cap structure still has some problems.

[0004] Specifically, since the inner cylinder 1a and the inner sealing plate 1b of the inner cover are produced separately, in order to improve production efficiency, a multi-cavity mold is usually used to simultaneously produce multiple inner cylinders 1a and multiple inner sealing plates 1b. During the production process, due to the limitations of the manufacturing process, the dimensions of these components have a certain tolerance range. If the dimensions of the inner cylinder 1a and the inner sealing plate 1b of a certain inner cover are both at the maximum tolerance limit, it may cause the buckle 1c of the outer cover to fail to accurately fit into the slot 1d of the inner cylinder. Since the outer cover is usually made of metal material, its strength is much higher than that of the inner cover. When the buckle and the slot cannot be accurately matched, the buckle of the outer cover will exert excessive pressure on the inner cylinder, causing the inner cylinder to deform inward. This deformation will further cause the inner cylinder and the wine spout of the fixed component to be squeezed, making it difficult for consumers to unscrew the upper cover assembly, affecting normal use.

[0005] On the other hand, if the dimensions of the inner cylinder 1a and inner sealing plate 1b of a particular inner cap are both within the minimum tolerance limit, a large axial gap will form between the buckle 1c and the latch groove 1d, causing the inner cap to wobble during use. This wobble not only produces collision noise, which degrades the user experience, but also may affect the sealing performance of the bottle cap, thereby reducing its anti-counterfeiting effectiveness. Utility Model Content

[0006] Based on this, the technical problem to be solved by the present invention is to provide an anti-counterfeiting bottle cap and an upper cover assembly thereof, which can improve user experience and product reliability.

[0007] The utility model provides an upper cover assembly of an anti-counterfeiting bottle cap, comprising:

[0008] The outer cover comprises an outer cylinder with an upper opening and a lower opening and an outer sealing plate for sealing the upper opening of the outer cylinder, wherein the inner wall of the outer cylinder is provided with a plurality of latching protrusions or latching grooves;

[0009] The inner cover comprises an inner cylinder with upper and lower openings and an inner sealing plate for closing the upper opening of the inner cylinder, wherein the outer wall of the inner cylinder is provided with a plurality of grooves or protrusions that cooperate with the plurality of grooves or protrusions on the outer cylinder;

[0010] An elastic structure is provided between the outer cover and the inner cover. When pressure is applied between the outer cover and the inner cover, the elastic structure is compressed, so that the latching protrusion can be snapped into the latching groove; when the pressure is released, the elastic structure returns to its initial state, and a pre-tightening elastic force is generated between the latching protrusion and the latching groove along the axial direction of the upper cover assembly.

[0011] The upper cover assembly of the above-mentioned anti-counterfeiting bottle cap is provided with an elastic structure between the outer cover and the inner cover. During the assembly process, the elastic structure is compressed to ensure that the buckle can be smoothly and completely inserted into the slot, avoiding the phenomenon that the inner cylinder is squeezed and deformed due to the buckle not being fully embedded, thereby making the bottle cap smoother during the opening and closing process. After the assembly is completed, the pressure is released and the elastic structure returns to its initial state, providing a stable pre-tightening force for the buckle and the slot, preventing the inner cover from shaking during use, and improving the connection stability and user experience of the bottle cap. The present application can compensate for the tolerance between the inner cover and the outer cover to a certain extent, ensure a smooth assembly process and a stable connection, avoid assembly problems caused by dimensional deviations, and improve production efficiency and product consistency.

[0012] In one embodiment, the inner cylinder and the inner sealing plate are split structures.

[0013] In one embodiment, the elastic structure is disposed between the inner sealing plate and the outer sealing plate.

[0014] In one embodiment, the elastic structure is provided at an edge of the inner sealing plate.

[0015] In one embodiment, the inner sealing plate includes a circular flat portion and a curved portion extending upward from the edge of the flat portion, wherein the curved portion constitutes the elastic structure.

[0016] In one embodiment, a sealing portion is provided on the edge of the flat portion, the sealing portion is in sealing cooperation with the upper end opening of the inner cylinder, and the sealing portion is connected to the curved portion.

[0017] In one embodiment, the inner cover further includes a cylindrical sealing ring, the outer diameter of the sealing ring is smaller than the inner diameter of the inner cylinder, and the upper end of the sealing ring is connected to the flat portion.

[0018] In one embodiment, the inner cylinder is made of hard plastic, and the inner sealing plate is made of soft plastic.

[0019] In one embodiment, the inner cylinder is made of ABS plastic, and the inner sealing plate is made of PE plastic.

[0020] An anti-counterfeiting bottle cap comprises a fixing assembly and the upper cover assembly.

[0021] The beneficial effects of the additional technical features of the present invention will be described in the specific implementation section of this specification. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the above-mentioned purposes, features, and advantages of the present invention more clearly understood, the following provides a clear and complete description of the specific embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the specific details described below are only a portion of the embodiments of the present invention, and the present invention can also be implemented in many other embodiments different from those described herein. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0027] In this document, when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The directional terms such as front, back, upper, and lower are defined based on the positions of the components in the drawings and in relation to each other, and are intended only for clarity and convenience in expressing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed in this application.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] like Figure 2 As shown, the anti-counterfeiting bottle cap as an example is mainly composed of a fixing assembly for fixing on the bottleneck (not shown in the figure), an upper cover assembly provided on the fixing assembly, and an anti-counterfeiting structure provided between the fixing assembly and the upper cover assembly, wherein the fixing assembly includes an inner body 1, an inner plug 2 and an outer body 4. The inner body 1 is cylindrical as a whole, and includes a liquid outlet portion 12 and a mounting portion 11 connected from top to bottom. The outer peripheral surface of the liquid outlet portion 12 is provided with an external thread 121 for connecting to the upper cover assembly. The upper section of the inner plug 2 is inserted into the liquid outlet portion 12 and is sealed with the inner wall of the liquid outlet portion 12. The lower section of the inner plug 2 can be inserted into the bottleneck and is sealed with the inner wall of the bottleneck.

[0030] The outer body 4 is cylindrical and is sleeved on the mounting portion 11 of the inner body 1. The outer body 4 serves as a decoration and, on the other hand, holds the mounting portion 11 of the inner body 1 to prevent deformation when the mounting portion 11 is heated.

[0031] Combine Figures 2 to 3As shown, the upper cover assembly includes an outer cover 6 and an inner cover 5 fixedly embedded in the outer cover 6. The outer cover 6 includes an outer cylinder 61 with an upper opening and a lower opening and an outer sealing plate 62 for closing the upper opening of the outer cylinder 61. The inner wall of the inner cover 5 is provided with an internal thread 51 that cooperates with the external thread 121 on the inner body 1. The inner wall of the outer cylinder 61 is provided with a plurality of latching protrusions 63. The inner cover 5 includes an inner cylinder 53 with an upper opening and a lower opening and an inner sealing plate 54 for closing the upper opening of the inner cylinder 53. The outer wall of the inner cylinder 53 is provided with a plurality of latching grooves 52 that cooperate with the plurality of latching protrusions 63. The latching protrusions 63 are snapped into the latching grooves 52 to fix the inner cover 5 and the outer cover 6. As an alternative, the positions of the latching protrusions 63 and the latching grooves 52 can be reversed, that is, the latching protrusions 63 are provided on the inner cover 5 and the latching grooves 52 are provided on the outer cover 6.

[0032] An elastic structure is provided between the outer cover 6 and the inner cover 5. When pressure is applied between the outer cover 6 and the inner cover 5, the elastic structure is compressed, so that the latching protrusion 63 can be snapped into the latching groove 52; when the pressure is released, the elastic structure returns to its initial state, and a pre-tightening elastic force is generated between the latching protrusion 63 and the latching groove 52 along the axial direction of the upper cover assembly.

[0033] By providing an elastic structure between the outer cap 6 and the inner cap 5, the elastic structure is compressed during assembly, ensuring that the buckle can be smoothly and completely inserted into the slot 52. This prevents the inner cylinder 53 from being squeezed and deformed due to the buckle not being fully inserted. This makes the bottle cap open and close more smoothly, improving the user experience. After installation, when the pressure is released, the elastic structure returns to its initial state, providing a stable pre-tightening force between the buckle and the slot 52, preventing the inner cap 5 from shaking during use, further improving the user experience.

[0034] In one embodiment, the inner cylinder 53 and the inner sealing plate 54 are split structures to facilitate processing.

[0035] In one embodiment, the elastic structure is arranged between the inner sealing plate 54 and the outer sealing plate 62. The elastic structure is arranged between the inner sealing plate 54 and the outer sealing plate 62, and is compressed when pressure is applied, which can effectively provide a uniform axial elastic force to ensure a stable connection between the outer cover 6 and the inner cover 5, while enhancing the sealing performance of the bottle cap to prevent liquid leakage. Furthermore, the elastic structure is specifically arranged at the edge of the inner sealing plate 54. The elastic structure is arranged at the edge of the inner sealing plate 54, so that the elastic force can be better distributed in the connection area of ​​the inner and outer covers 6, further improving the connection stability. At the same time, the elastic structure at the edge can respond more sensitively to external pressure during the installation and opening process, thereby improving the convenience of using the bottle cap.

[0036] In one embodiment, the inner sealing plate 54 consists of a circular flat portion 541 and a curved portion 542. The curved portion 542 extends upward from the edge of the flat portion 541, forming an elastic structure. The elastic structure of the curved portion 542 can produce axial elastic deformation when subjected to force, providing greater cushioning and rebound effects, effectively preventing the buckle from loosening or falling off. At the same time, the curved structure improves the durability and sealing performance of the bottle cap. Alternatively, the elastic structure can be formed as a protrusion on the upper surface of the inner sealing plate 54 or the lower surface of the outer sealing plate.

[0037] In one embodiment, a sealing portion 543 is provided on the edge of the flat portion 541. The sealing portion 543 seals against the upper opening of the inner cylinder 53 and is connected to the curved portion 542. The sealing portion 543 is tightly fitted against the upper end surface of the inner cylinder 53 to prevent leakage between the upper end surface of the inner cylinder 53 and the lower surface of the inner sealing plate 54.

[0038] In one embodiment, the inner cylinder 53 is made of hard plastic and the inner sealing plate 54 is made of soft plastic. Since at least the portion of the inner cover 5 provided with the card slot 52 is made of hard plastic and the inner sealing plate 54 that cooperates with the end face of the liquid outlet portion 12 is made of soft plastic, the inner cover 5 increases the connection strength with the outer cover 6 while meeting the sealing requirements. When the upper cover assembly is heated with a hair dryer or hot water, the inner cylinder 53 is not easily deformed, thereby achieving the goal of not being able to pull the outer cover 6 out of the inner cover 5 by heating means. Only by heating the outer cover 6 to deform can the card protrusion 63 and the card slot 52 be separated, achieving the goal of only destroying the bottle cap to pull out the bottle cap, making the bottle cap disposable, achieving the purpose of destroying the cap, and the cap cannot be recycled, with good anti-counterfeiting effect. Preferably, the inner cylinder 53 is made of ABS plastic and the inner sealing plate 54 is made of PE (polyethylene) plastic.

[0039] In one embodiment, the lower surface of the inner sealing plate 54 has a downwardly extending sealing ring 55. The sealing ring 55 is made of soft plastic and is used to closely contact the liquid outlet portion 12 when the bottle cap is fully tightened. The sealing ring 55 provides good sealing performance to prevent liquid leakage.

[0040] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
