Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, specifically a pry-open anti-theft ring cap. Background Technology

[0002] Anti-theft bottle caps mainly consist of an anti-theft ring and the cap body. Typically, the anti-theft ring and the cap body are integrally formed and connected via multiple anti-theft connection points. The design of the anti-theft ring bottle cap is primarily for verifying whether the bottle is a new, unopened package.

[0003] Currently, most anti-theft bottle caps are screw-on tamper-evident ring caps. The cap body is threaded onto the bottle opening; twisting the cap body disconnects the tamper-evident ring, allowing the cap to be opened. Another type of anti-theft bottle cap is the tear-off tamper-evident ring cap, which requires the tamper-evident ring to be removed before unscrewing the cap. Because tear-off tamper-evident ring caps are more difficult to remove, screw-on tamper-evident ring caps are the mainstream product on the market.

[0004] However, in practical applications, both of the aforementioned anti-theft bottle caps require unscrewing the cap body from the bottle opening when opening, which can easily lead to the cap body falling off or being lost, thus limiting their usability. To address this, we designed a pry-open anti-theft ring cap. The cap body is designed to be pry open, maintaining connection with the anti-theft ring even when opened, preventing it from falling off or being lost. It is also easy to open and close without needing to unscrew the cap, making it convenient and highly practical. Utility Model Content

[0005] The purpose of this invention is to provide a pry-open anti-theft ring cover to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pry-open anti-theft ring cap includes an anti-theft ring and a bottle cap body fixedly connected to the anti-theft ring through multiple anti-theft connection points. An inner retaining ring is provided on the inner side of the anti-theft ring, and the rear side of the anti-theft ring is fixedly connected to the bottle cap body through an anti-detachment connecting plate. The anti-detachment connecting plate is used to prevent the anti-theft ring from separating from the bottle cap body. A limiting inner ring is fixedly provided at the bottom of the bottle cap body, and a limiting slot for clamping the bottle mouth is formed between the limiting inner ring and the outer wall of the bottle cap body. An opening locking component is provided on the rear side of the bottle cap body to automatically keep the bottle cap body in the open state.

[0008] As a further preferred embodiment of this utility model: the opening locking assembly includes a rear locking plate fixedly disposed on the rear side of the bottle cap body, and a limiting top plate is provided on the rear side of the anti-theft ring. When the bottle cap body opens backward, the rear locking plate can press against the rear side of the limiting top plate.

[0009] As a further preferred embodiment of this utility model: a push plate is provided on the front side of the bottle cap body for pushing the bottle cap body upward.

[0010] As a further preferred embodiment of this utility model: a limiting stop corresponding to the inner retaining ring is provided on the front side of the inner wall of the bottle cap body.

[0011] As a further preferred embodiment of this utility model: two anti-detachment connecting plates are symmetrically arranged, and the limiting top plate is located between the two anti-detachment connecting plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This pry-open anti-theft ring cap has a scientifically and rationally designed structure. To open the bottle cap, simply push the cap body upwards to disconnect the anti-theft connection point between the anti-theft ring and the cap body. The anti-detachment connecting plate ensures that the rear of the cap body remains connected to the anti-theft ring, preventing the cap from falling off. Furthermore, a rear locking plate and a limiting top plate are installed on the rear of both the cap body and the anti-theft ring. When the cap body is in its fully open state, the rear locking plate can push against the back of the limiting top plate, limiting the cap body and automatically locking it in the open position. This ensures the bottle opening is always at its maximum open state, making it convenient to use, with a simple and innovative design and strong practicality. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figure 1-5 This embodiment provides a pry-open type anti-theft ring cap, including an anti-theft ring 1 and a bottle cap body 2 fixedly connected to the anti-theft ring 1 through multiple anti-theft connection points 3. An inner retaining ring 8 is provided inside the anti-theft ring 1, which is used to lock the anti-theft ring 1 to the bottom of the bottle opening. At the same time, in order to ensure the stability of the inner retaining ring 8, a triangular reinforcing block 12 is provided inside the anti-theft ring 1 at the lower part of the inner retaining ring 8. It should be noted that the structure of the anti-theft ring 1, the anti-theft connection points 3 and the bottle cap body 2 and their connection relationship should be conventional anti-theft ring cap structures familiar to those skilled in the art, and this application will not elaborate further.

[0022] In this application, as Figure 2 as well as Figure 4 As shown, the anti-theft ring 1 is fixedly connected to the bottle cap body 2 via an anti-detachment connecting plate 6 on the rear side. The anti-detachment connecting plate 6 is used to prevent the anti-theft ring 1 from separating from the bottle cap body 2. It should be noted that, as is common sense, the anti-detachment connecting plate 6 should have a certain degree of elasticity and be able to deform. It is integrally formed with the anti-theft ring 1 and the bottle cap body 2.

[0023] Furthermore, to ensure good stability when the bottle cap body 2 is attached to the bottle opening, such as... Figure 2 , Figure 3 as well as Figure 5 As shown, a limiting inner ring 10 is fixedly provided at the bottom of the bottle cap body 2, and a limiting slot 11 for clamping the bottle mouth is formed between the limiting inner ring 10 and the outer wall of the bottle cap body 2. The limiting slot 11 is integrally formed with the bottle cap body 2. When the bottle cap body 2 is fastened to the bottle mouth, the mouth wall is located in the limiting slot 11, and the outer wall of the bottle cap body 2 cooperates with the limiting inner ring 10 to clamp the bottle mouth, ensuring the stability of the bottle cap body 2 on the bottle mouth. At the same time, a limiting stop 9 corresponding to the inner ring 8 is provided on the front side of the inner wall of the bottle cap body 2, which can further ensure the stability of the bottle cap body 2 fastened to the bottle mouth.

[0024] Meanwhile, considering that the bottle cap body 2 is only connected to the anti-theft ring 1 via the anti-detachment connecting plate 6 after opening, and since the anti-detachment connecting plate 6 has a certain degree of elasticity, in order to prevent the bottle cap body 2 from shaking during use and affecting the opening degree of the bottle mouth, an opening locking component is provided on the rear side of the bottle cap body 2 to automatically keep the bottle cap body 2 in the open state. For example... Figure 2-4 As shown, the opening locking assembly includes a rear locking plate 5 fixedly disposed on the rear side of the bottle cap body 2, and a limiting top plate 7 disposed on the rear side of the anti-theft ring 1. When the bottle cap body 2 opens backward, the rear locking plate 5 can press against the rear side of the limiting top plate 7. It should be noted that the rear locking plate 5 is integrally formed with the bottle cap body 2, and the limiting top plate 7 is integrally formed with the anti-theft ring 1. Both have a certain degree of elasticity, which facilitates the opening and closing of the bottle cap body 2. Preferably, two anti-detachment connecting plates 6 are symmetrically arranged, and the limiting top plate 7 is located between the two anti-detachment connecting plates 6.

[0025] In addition, such as Figure 1 As shown, in order to facilitate opening the bottle cap body 2, a front push plate 4 is provided on the front side of the bottle cap body 2 to push the bottle cap body 2 upward.

[0026] It should be noted that, as is common knowledge familiar to those skilled in the art, the anti-theft ring cover is integrally formed, and its material selection should be a common choice familiar to those skilled in the art. This application will not elaborate on the limitations.

[0027] In practical applications, when it is necessary to open the bottle cap body 2, push the front push plate 4 with your thumb to move the bottle cap body 2 upward, causing the anti-theft connection point 3 to disconnect, and the bottle cap can be opened. At this time, the bottle cap body 2 is always connected to the anti-theft ring 1 through the anti-detachment connection plate 6. Continue to rotate the bottle cap body 2 backward. When the bottle cap body 2 rotates backward more than 180 degrees, the rear locking plate 5 will lock onto the rear side of the limiting top plate 7 to prevent the bottle cap body 2 from resetting, so that the bottle cap body 2 is always in the fully open state. When it is necessary to close the bottle mouth, push the bottle cap body 2 forward to release the limiting top plate 7 from limiting the rear locking plate 5, and the bottle cap body 2 can be fastened to the bottle mouth. The operation is convenient.

[0028] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0029] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
