Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, specifically to a simple anti-counterfeiting bottle cap and container bottle. Background Technology

[0002] In the packaging of food, beverages, and alcoholic beverages, bottle caps, as key sealing components, not only need to have reliable sealing performance to ensure product quality, but also need to meet multiple requirements such as anti-counterfeiting, anti-tampering, and ease of use. Taking alcoholic beverages as an example, these bottle caps typically include multiple components such as an outer cap, an outer sleeve, a liner cap, an inner stopper, and an inner sleeve.

[0003] However, in some low- to mid-range (especially low-end) alcoholic beverages, simplified bottle caps (i.e., omitting some components) are used to reduce costs. For example, simplified bottle caps are disclosed in patent documents such as "CN205707973U" and "CN208994262U". While these simplified bottle caps achieve anti-counterfeiting functions, they still contain a relatively large number of components (for example, even the technology with the fewest parts, "CN208994262U", includes four components: a top cap, an outer sleeve, an inner sleeve, and an outer cylinder). Their insufficient simplification restricts further reductions in production costs and assembly process difficulty, making it difficult to meet the core demands of large-scale, low-cost production of low- to mid-range (especially low-end) alcoholic beverages. Utility Model Content

[0004] The purpose of this invention is to provide a simple anti-counterfeiting bottle cap and container to solve the above-mentioned defects of the prior art.

[0005] This utility model is achieved through the following technical solution: A simple anti-counterfeiting bottle cap includes a sealing plug, an outer cap, and an outer sleeve that can be fixed to the bottle body. The sealing plug is inserted inside the outer sleeve and can form a sealing pair with the bottle mouth. The bottom side of the outer cover has several anti-counterfeiting teeth, and the outer side of the outer cover has a notch to accommodate the anti-counterfeiting teeth; The outer cover and the outer sleeve are connected by threads. The upper threaded surface of the outer sleeve and / or the lower threaded surface of the outer cover have guide ramps. Both the lower threaded surface of the outer sleeve and the upper threaded surface of the outer cover are limiting planes.

[0006] Furthermore, the outer wall of the outer jacket is provided with a limiting step in the middle that abuts against the bottom surface of the outer cover.

[0007] Furthermore, the outer casing has a sealing cylinder at its center that is inserted into the bottle neck to form a sealing pair. The sealing plug includes a ring plate and a plug cylinder located at the bottom of the ring plate. The ring plate abuts against the top of the sealing cylinder, and the plug cylinder is interference-fitted with the inside of the sealing cylinder.

[0008] Furthermore, the inner and outer edges of the top of the sealing cylinder are both pointed.

[0009] Furthermore, the inner wall of the outer cover is provided with a plurality of hook platforms along the circumferential direction, and the hook platforms are located below the ring plate.

[0010] Furthermore, the inner top of the outer cover is provided with a guide post, and the top of the sealing plug is provided with a guide hole that can cooperate with the guide post.

[0011] Furthermore, the end of the guide post and the guide hole have a tapered structure that matches each other.

[0012] Furthermore, the guide hole sidewall is provided with a plurality of first anti-rotation teeth, and the guide post sidewall is provided with a plurality of second anti-rotation teeth that can cooperate with the first anti-rotation teeth.

[0013] Furthermore, a number of reinforcing ribs are provided along the circumferential direction between the guide post and the inner wall of the outer cover.

[0014] This utility model also provides a container bottle, including a bottle body and a simple anti-counterfeiting bottle cap as described in any one of the above. The inner wall of the outer sleeve is provided with a limiting ring platform, and the outer side of the bottle neck is provided with a limiting ring groove for accommodating the limiting ring platform. The inner wall of the outer sleeve is provided with a plurality of third anti-rotation teeth, and the outer side of the bottle mouth is provided with a plurality of anti-rotation ribs that can cooperate with the third anti-rotation teeth along the circumferential direction.

[0015] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, the bottle cap only includes three parts: a sealing plug, an outer cap, and an outer sleeve, which further reduces the number of parts of the bottle cap, effectively reduces production costs and assembly process difficulty, and better meets the core demand of large-scale and low-cost production of mid-to-low-end (especially low-end) alcoholic beverages; at the same time, the anti-counterfeiting teeth at the bottom of the outer cap cooperate with the notch on the outside of the outer sleeve, combined with the guide slope in the threaded connection structure of the outer cap and the outer sleeve to facilitate assembly and the limiting plane to ensure connection stability. On the basis of simplifying the structure, it not only achieves reliable anti-counterfeiting function, but also ensures sealing performance through the sealing pair formed by the sealing plug and the bottle mouth, solving the technical problems of insufficient simplicity of existing simple bottle caps and difficulty in balancing cost, assembly efficiency, anti-counterfeiting and sealing requirements.

Detailed Implementation

[0017] refer to Figure 1 and Figure 2 A simple anti-counterfeiting bottle cap, comprising a sealing plug 3, an outer cap 1, and an outer sleeve 2, consists of only three parts. This further reduces the number of components in the bottle cap, effectively lowering production costs and assembly complexity, and better meeting the core demands of large-scale, low-cost production of mid-to-low-end (especially low-end) alcoholic beverages. In practical applications, the outer sleeve 2 is fixed to the bottle opening of the bottle body 6, and the sealing plug 3 is inserted inside the outer sleeve 2, forming a sealing pair with the bottle opening to ensure the airtightness of the beverage inside the bottle.

[0018] refer to Figures 2-6 The outer cover 1 has several anti-counterfeiting teeth 101 on one side of its bottom, and the outer cover 2 has a notch 201 on its outer side to accommodate the anti-counterfeiting teeth 101. The outer cover 1 and the outer cover 2 are connected by threads. Furthermore, in this embodiment, the upper threaded surface of the outer cover 2 and the lower threaded surface of the outer cover 1 both have guide slopes 4 (in other embodiments, the guide slopes 4 can of course be set only on the upper threaded surface of the outer cover 2 or the lower threaded surface of the outer cover 1). The lower threaded surface of the outer cover 2 and the upper threaded surface of the outer cover 1 are both limiting planes 5.

[0019] In practical applications, the threads on the inner wall of the outer cap 1 are designed as segments on a spiral (rather than a complete spiral). In other words, the threads on the inner wall of the outer cap 1 appear as several bosses, which should be located on the spiral. The various components of the bottle cap are typically plastic. During assembly, due to the presence of the guide slope 4, the outer cap 1 can be press-fitted into place with the outer sleeve 2 (avoiding damage to the anti-counterfeiting teeth 101 caused by screwing on the outer cap 1). After assembly, under the action of the limiting plane 5, the outer cap 1 is difficult to pull out; the bottle cap can only be opened by rotating the outer cap 1. During the rotation of the outer cap 1, the anti-counterfeiting teeth 101 are broken, ensuring the anti-counterfeiting performance of the bottle cap. Therefore, this utility model, while simplifying the structure, achieves reliable anti-counterfeiting functionality and ensures sealing performance through the sealing pair formed by the sealing plug 3 and the bottle mouth. It solves the technical problems of existing simple bottle caps, such as insufficient simplicity, difficulty in balancing cost, assembly efficiency, anti-counterfeiting, and sealing requirements.

[0020] The outer wall of the outer jacket 2 has a limiting step 202 in the middle that abuts against the bottom surface of the outer cover 1, which facilitates the assembly of the outer cover 1 and the outer jacket 2. It is easy to understand that the limiting step 202 divides the outer jacket 2 into upper and lower sections. The upper section is connected to the outer cover 1 by threads, while the lower section is exposed outside. In order to ensure aesthetics, the outer diameter of the lower section of the outer jacket 2 can be equal to the outer diameter of the outer cover 1.

[0021] refer to Figure 2 as well as Figures 5-8 The outer casing 2 has a sealing cylinder 203 at its center, which is inserted into the bottle neck to form a sealing pair. The sealing plug 3 includes a ring plate 301 and a plug cylinder 302 located at the bottom of the ring plate 301. In actual applications, the ring plate 301 and the plug cylinder are integrally injection molded. After the sealing plug 3 is installed, the ring plate 301 abuts against the top of the sealing cylinder 203 to ensure that the sealing plug 3 will not fall into the bottle; the plug cylinder 302 is interference-fitted with the inside of the sealing cylinder 203 to form a sealing pair, ensuring the airtightness of the beverage inside the bottle.

[0022] The sealing cylinder 203 extends upwards from the bottle opening, acting as a spout. Taking a wine bottle as an example, when pouring wine, the liquid flows out from the top edge of the sealing cylinder 203. In this embodiment, the inner and outer edges of the top of the sealing cylinder 203 are pointed, meaning they are neither rounded nor right-angled, retaining a sharp corner structure. It is worth noting that this design can prevent "swirl," that is, it can, to a certain extent, prevent the liquid from flowing along the top edge of the sealing cylinder 203 onto the outer wall of the bottle body 6 after pouring.

[0023] refer to Figures 2-4 as well as Figure 7 and Figure 8The inner wall of the outer cover 1 is provided with several hooks 102 along the circumferential direction, and the hooks 102 are located below the ring plate 301. With this design, when the outer cover 1 is unscrewed, the hooks 102 can apply an upward force to the ring plate 301, so that the sealing plug 3 can be removed at the same time as the outer cover 1 is unscrewed, without having to remove the sealing plug 3 by pulling it, which is more convenient for consumers; moreover, the sealing plug 3 remains on the outer cover 1 after being removed, preventing it from falling off.

[0024] The inner top of the outer cover 1 is provided with a guide post 103, and the top of the sealing plug 3 is provided with a guide hole 303 that can cooperate with the guide post 103 to facilitate the guidance of the outer cover 1 during press-fitting. Furthermore, the end of the guide post 103 and the guide hole 303 are in a mutually cooperating tapered structure. This design ensures the guiding performance while facilitating the alignment of the outer cover 1 and the sealing plug 3.

[0025] Based on the above, the sidewall of the guide hole 303 is provided with several first anti-rotation teeth 3031, and the sidewall of the guide post 103 is provided with several second anti-rotation teeth 1031 that can cooperate with the first anti-rotation teeth 3031. It is worth noting that, since the sealing plug 3 and the sealing cylinder 203 are interference-fitted, it is difficult to remove the sealing plug 3 by directly applying an upward force. Through the combined action of the first anti-rotation teeth 3031 and the second anti-rotation teeth 1031, the relative rotation between the sealing plug 3 and the outer cover 1 can be restricted. In this way, when the outer cover 1 is unscrewed, the sealing plug 3 can be rotated (even if the sealing plug 3 and the sealing cylinder 203 rotate relative to each other, making them loose), which helps to remove the sealing plug 3 more easily when the outer cover 1 is unscrewed.

[0026] Several reinforcing ribs 104 are provided along the circumferential direction between the guide post 103 and the inner wall of the outer cover 1. The reinforcing ribs 104 ensure the structural strength of the outer cover 1 itself, and can also act as a limit for the upward displacement of the sealing plug 3 after assembly. That is, the bottom surface of the reinforcing rib 104 abuts against the ring plate 301 of the sealing plug 3, or the bottom surface of the reinforcing rib 104 leaves a very small distance from the top surface of the ring plate 301.

[0027] refer to Figure 2 , Figure 6 and Figure 9 This utility model also provides a container bottle, including a bottle body 6 and the aforementioned simple anti-counterfeiting bottle cap. As an option, in this embodiment, the outer sleeve 2 and the bottle body 6 are fixed in the following way: the inner wall of the outer sleeve 2 is provided with a limiting ring platform 204, and the outer side of the bottle neck is provided with a limiting ring groove 601 that accommodates the limiting ring platform 204. The limiting ring platform 204 and the limiting ring groove 601 work together to restrict the axial detachment of the outer sleeve 2 and the bottle body 6. The inner wall of the outer sleeve 2 is provided with a plurality of third anti-rotation teeth 205, and the outer side of the bottle mouth is provided with a plurality of anti-rotation ribs 602 that can cooperate with the third anti-rotation teeth 205 along the circumferential direction. The anti-rotation ribs 602 and the third anti-rotation teeth 205 work together to restrict the circumferential rotation of the outer sleeve 2 and the bottle body 6.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
