Technical Problem

[0002]防拔起瓶盖的技术背景主要源于市场对产品安全、防伪及质量保障的迫切需求,尤其在酒类、药品等高价值商品领域,传统瓶盖设计存在显著缺陷,例如塑料材质在高温下易软化,导致瓶盖可被完整拔出后替换内容物,为假冒伪劣产品提供了可乘之机

Benefits of technology

[0016]1. The outer wall of the tapered pattern is a tapered ring with the tapered surface facing the bottom. Multiple elastic rubber rings are installed at the connection between the tapered pattern and the outer wall of the bottle cap. This increases the friction coefficient between the tapered pattern and the claw. The direction of friction is perpendicular to the pulling direction, which prevents the claw from pulling out the bottle cap. At the same time, the inner wall of the cap has a space that matches the elastic ball and telescopic column. The inner wall of the cap also has an elastic groove that matches the surface metal spring. This allows the telescopic column to move and drive the elastic ball to move and squeeze the top of the cap. This causes the metal piece at the top of the cap to protrude and form an arc structure. This prevents the claw from stably engaging on the arc surface at the top of the cap, thus preventing the bottle cap from being pulled directly out of the bottle.

Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, specifically to a bottle cap that prevents the clips from being pulled off. Background Technology

[0002] The technological background of anti-pull-out bottle caps mainly stems from the market's urgent need for product safety, anti-counterfeiting, and quality assurance. Especially in the field of high-value commodities such as alcohol and pharmaceuticals, traditional bottle cap designs have significant defects. For example, plastic materials are prone to softening at high temperatures, which allows the bottle cap to be completely pulled out and the contents replaced, providing an opportunity for counterfeit and shoddy products.

[0003] A search revealed a utility model patent, CN 219278251U, for an anti-pull bottle cap. This patent uses an anti-pull block to restrict the upward pulling of the sealing cap, thus preventing it from being pulled out. The structure is simple and does not affect the bottle's seal. The invention also includes a warning light that detects changes in the bottle's internal pressure to assess the seal and prevent leaks. Furthermore, the anti-pull block, along with a bottle mouth limiting plate, prevents the cap from being pulled out directly, thus achieving the anti-pull function.

[0004] The aforementioned patent uses an anti-pull-out block to prevent the cap from being pulled out by relying on the bottle mouth limiting plate. This prevents the cap from being pulled out directly upwards, thus achieving the anti-pull-out function. However, existing bottle caps can be pulled out from the top of the bottle without damage by a claw-type cap opener, allowing the caps to be reused on counterfeit and substandard products.

[0005] Therefore, it is necessary to propose a bottle cap that prevents the clips from being pulled off in order to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a bottle cap that prevents the cap from being pulled out by the claw. Through the cooperation of the internal parts of the anti-pull mechanism, the cap cylinder and the bottle body are easily connected and fixed by threads. At the same time, the outer wall of the cap cylinder and the outer wall of the cap top are both arc-shaped, which makes it easy for the claw to slip when it is engaged with the outer wall of the cap cylinder and the cap top. This prevents the claw-type bottle opener from pulling out the cap. Through the cooperation of the internal parts of the connecting mechanism, the arc surface of the top of the cap is easily controlled, so that the top surface of the cap and the claw cannot be firmly engaged. This solves the problem in the prior art that the cap can be pulled out from the top of the bottle body without damage by the claw-type cap opener, thus allowing the cap to be reused on counterfeit and shoddy products.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bottle cap for preventing the claw from pulling out, comprising a bottle cap cylinder, a cap top installed at the top of the bottle cap cylinder, an anti-pull-out mechanism connected to the outer wall of the bottle cap cylinder, and a connecting mechanism connected to the bottom end of the cap top, which is located on the inner wall of the bottle cap cylinder.

[0008] The anti-pull mechanism includes conical patterns, and there are multiple conical patterns. The multiple conical patterns are nested around the outer wall of the bottle cap cylinder. The inner wall of the bottle cap cylinder is provided with internal threads. A first groove is opened on both sides of the top of the bottle cap cylinder. A second groove is also opened at both ends of the top of the bottle cap cylinder and is located between the first groove.

[0009] The connecting mechanism includes a connecting column, which is mechanically fixed to the bottom end of the cap and slidably connected to the inner wall of the cap cylinder. A sealing plate is fixed to the inner wall of the cap cylinder and located below the connecting column. A telescopic column is mechanically fixed to the top of the sealing plate and extends through the interior of the connecting column.

[0010] Preferably, the connecting mechanism further includes an elastic ball, which is fixed to the top of the telescopic column and elastically connected to the top of the cap. A connecting ring is sleeved and fixed on the outer wall of the connecting column, located above the sealing plate, and slidably connected to the inner wall of the cap cylinder. A telescopic spring is mechanically connected between the top of the connecting ring and the inner wall of the cap cylinder, and sleeved on the outer wall of the connecting column.

[0011] Preferably, the outer wall of the cover is machined with an arc-shaped block, and the inner walls of the second groove and the first groove are fitted with the outer wall of the arc-shaped block, and the inner wall depths of the second groove and the first groove are not the same.

[0012] Preferably, the surface of the cap is provided with an arc-shaped metal spring, the outer wall of the conical pattern is a conical ring with the conical surface facing the bottom, and multiple elastic rubber rings are installed at the connection between the multiple conical patterns and the outer wall of the bottle cap.

[0013] Preferably, the inner wall of the bottle cap cylinder is provided with a telescopic groove that matches the connecting ring, and the bottom end of the sealing plate is sealed to the bottom end of the bottle cap cylinder.

[0014] Preferably, the inner wall of the cover has an active space that matches the elastic ball and the telescopic column, and the inner wall of the cover has an elastic groove that matches the surface metal spring sheet.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The outer wall of the tapered pattern is a tapered ring with the tapered surface facing the bottom. Multiple elastic rubber rings are installed at the connection between the tapered pattern and the outer wall of the bottle cap. This increases the friction coefficient between the tapered pattern and the claw. The direction of friction is perpendicular to the pulling direction, which prevents the claw from pulling out the bottle cap. At the same time, the inner wall of the cap has a space that matches the elastic ball and telescopic column. The inner wall of the cap also has an elastic groove that matches the surface metal spring. This allows the telescopic column to move and drive the elastic ball to move and squeeze the top of the cap. This causes the metal piece at the top of the cap to protrude and form an arc structure. This prevents the claw from stably engaging on the arc surface at the top of the cap, thus preventing the bottle cap from being pulled directly out of the bottle.

[0017] 2. By rotating the bottle cap cylinder, the internal threads on the inner wall of the bottle cap cylinder separate from the threads on the outer wall of the bottle. At the same time, by pulling the cap top, the force on the cap top causes the connecting pin to drive the connecting ring to compress and move the telescopic spring, causing the connecting pin to slide on the outer wall of the telescopic pin, thus separating the cap top from the top of the bottle cap cylinder. Rotating the cap top causes the arc-shaped surface of the outer wall to move from inside the second groove to the inner wall of the first groove, creating a certain height difference between the cap top and the inner wall of the bottle cap cylinder. Simultaneously, the telescopic movement of the cap top causes the elastic ball at the top of the telescopic pin to generate tension, causing the metal sheet on the surface of the cap top to deform, making the arc-shaped metal sheet concave. This facilitates the engagement of the claws on the surface of the cap top, allowing the bottle cap cylinder to be pulled out from the bottle body. At the same time, the internal threads on the inner wall of the bottle cap cylinder sliding on the outer wall of the bottle will cause damage and stripping, thus preventing the bottle cap from being pulled out from the top of the bottle without damage, allowing the bottle cap to be reused on counterfeit and inferior products.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The bottle cap shown includes a cap cylinder 1, a cap top 101 installed at the top of the cap cylinder 1, an anti-pull mechanism 2 connected to the outer wall of the cap cylinder 1, and a connecting mechanism 3 connected to the bottom of the cap top 101 and located on the inner wall of the cap cylinder 1.

[0028] The anti-pull mechanism 2 includes a tapered pattern 201, and there are multiple tapered patterns 201. The multiple tapered patterns 201 are nested around the outer wall of the bottle cap cylinder 1. The inner wall of the bottle cap cylinder 1 is provided with an internal thread 202. A first groove 203 is opened on both sides of the top end of the bottle cap cylinder 1. A second groove 204 is also opened at both ends of the top end of the bottle cap cylinder 1 and is located between the first groove 203.

[0029] The connecting mechanism 3 includes a connecting post 301, which is mechanically fixed to the bottom end of the cap top 101 and slidably connected to the inner wall of the cap cylinder 1. A sealing plate 302 is fixed to the inner wall of the cap cylinder 1 and is located below the connecting post 301. A telescopic post 303 is mechanically fixed to the top of the sealing plate 302 and extends through the interior of the connecting post 301.

[0030] Through the cooperation of the internal parts of the anti-pull mechanism 2, the bottle cap cylinder 1 and the bottle body can be connected and fixed by threads. At the same time, the outer wall of the bottle cap cylinder 1 and the outer wall of the cap top 101 are both arc-shaped, which makes it easy for the claw to slip when it is engaged with the outer wall of the bottle cap cylinder 1 and the cap top 101. This helps to prevent the claw-type bottle opener from pulling out the bottle cap. Through the cooperation of the internal parts of the connecting mechanism 3, the arc surface of the top of the cap top 101 can be controlled, so that the top surface of the cap top 101 cannot be firmly engaged with the claw.

[0031] Refer to the instruction manual appendix Figure 1-5The connecting mechanism 3 also includes an elastic ball 304, which is fixed to the top of the telescopic column 303 and elastically connected to the top of the cap 101. A connecting ring 305 is fixedly sleeved on the outer wall of the connecting column 301 and is located above the sealing plate 302 and slidably connected to the inner wall of the cap cylinder 1. A telescopic spring 306 is mechanically connected between the top of the connecting ring 305 and the inner wall of the cap cylinder 1 and is sleeved on the outer wall of the connecting column 301. Through the mutual cooperation between the internal parts of the connecting mechanism 3, it is easy to control the arc surface of the top of the cap 101, so that the top surface of the cap 101 cannot be firmly locked with the claw.

[0032] Refer to the instruction manual appendix Figure 1-5 The outer wall of the cover 101 is machined with an arc-shaped block, and the inner walls of the second groove 204 and the first groove 203 are fitted with the outer wall of the arc-shaped block. The inner wall depths of the second groove 204 and the first groove 203 are not the same. The arc-shaped block on the outer wall of the cover 101, and the inner walls of the second groove 204 and the first groove 203 are fitted with the outer wall of the arc-shaped block, and the inner wall depths of the second groove 204 and the first groove 203 are not the same, make it easy for the cover 101 to engage with the second groove 204 and the first groove 203 respectively through the arc-shaped block.

[0033] Refer to the instruction manual appendix Figure 1-5 The surface of the cap 101 is provided with an arc-shaped metal spring. The outer wall of the conical pattern 201 is a conical ring with the conical surface facing the bottom. Multiple elastic rubber rings are installed at the connection between the multiple conical patterns 201 and the outer wall of the cap cylinder 1. The conical pattern 201 has a conical ring on its outer wall with the conical surface facing the bottom. The multiple elastic rubber rings at the connection between the multiple conical patterns 201 and the outer wall of the cap cylinder 1 facilitate the increase of the friction coefficient between the conical pattern 201 and the claw. The direction of the friction force is perpendicular to the pull-out direction, which prevents the claw from pulling out the cap.

[0034] Refer to the instruction manual appendix Figure 1-5 The inner wall of the bottle cap cylinder 1 is provided with a telescopic groove that matches the connecting ring 305. The bottom end of the sealing plate 302 is sealed to the bottom end of the bottle cap cylinder 1. The sealing connection between the bottom end of the sealing plate 302 and the bottom end of the bottle cap cylinder 1 facilitates the improvement of the sealing performance of the inner wall of the bottle cap cylinder 1.

[0035] Refer to the instruction manual appendix Figure 1-5 The inner wall of the cover 101 has an active space that matches the elastic ball 304 and the telescopic column 303, and the inner wall of the cover 101 has an elastic groove that matches the surface metal sheet. The active space that matches the elastic ball 304 and the telescopic column 303 and the elastic groove that matches the surface metal sheet facilitates the movement of the telescopic column 303 to drive the elastic ball 304 to move and squeeze the top of the cover 101, so that the metal sheet at the top of the cover 101 protrudes and forms an arc-shaped structure.

[0036] The working principle of this practical application is as follows:

[0037] Refer to the instruction manual appendix Figure 1-5 The outer wall of the tapered pattern 201 is a tapered ring with the tapered surface facing the bottom. Multiple elastic rubber rings are installed at the connection between the tapered pattern 201 and the outer wall of the bottle cap cylinder 1. This increases the friction coefficient between the tapered pattern 201 and the claw. The direction of friction is perpendicular to the pulling direction, which prevents the claw from pulling out the bottle cap. At the same time, the inner wall of the cap top 101 has an active space that matches the elastic ball 304 and the telescopic column 303. The inner wall of the cap top 101 also has an elastic groove that matches the surface metal spring. This allows the telescopic column 303 to move and drive the elastic ball 304 to move and squeeze the top of the cap top 101. This causes the metal piece at the top of the cap top 101 to protrude and form an arc structure. This prevents the claw from being stably engaged on the arc surface at the top of the cap top 101, thus preventing the bottle cap cylinder 1 from being pulled directly out of the bottle.

[0038] Refer to the instruction manual appendix Figure 1-5 By rotating the bottle cap cylinder 1, the inner thread 202 of the inner wall of the bottle cap cylinder 1 separates from the outer thread of the bottle cap cylinder 1. At the same time, by pulling the cap top 101, the cap top 101 is subjected to force, which drives the connecting ring 305 through the connecting post 301 to compress the telescopic spring 306 and move it. This causes the connecting post 301 to slide on the outer wall of the telescopic post 303, separating the cap top 101 from the top of the bottle cap cylinder 1. Rotating the cap top 101 causes the arc-shaped surface of the outer wall to move from inside the second groove 204 to the inner wall of the first groove 203, causing the cap top 101 to telescopically move and interact with the bottle cap cylinder 1. There is a certain height difference between the inner walls. At the same time, when the cap 101 moves telescopically, it drives the elastic ball 304 at the top of the telescopic column 303 to generate a pulling force, causing the metal sheet on the surface of the cap 101 to deform and the arc-shaped metal sheet to be concave. This makes it easier for the claw to engage on the surface of the cap 101, so that the cap tube 1 can be pulled out from the surface of the bottle. Meanwhile, the internal thread 202 on the inner wall of the cap tube 1 will slide on the outer wall of the bottle and cause damage and stripping. Therefore, the cap can be pulled out from the top of the bottle without damage, so that the cap can be reused on counterfeit and shoddy products.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
