Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, and more specifically, to a bottle cap with regularly thick and thin bridge points. Background Art

[0002] With the increasing pursuit of the quality of life by consumers, higher requirements are also put forward for the detailed experience of daily necessities. In the beverage packaging industry, the break-ring torque of plastic bottle caps is one of the key factors affecting the opening experience of consumers. Reasonable control of the break-ring torque can not only ensure the sealing performance of products, but also meet the comfort and satisfaction of consumers when opening the bottle caps. At present, there are some problems in the commonly used bottle cap designs on the market, such as the uneven number and cross-sectional area of bridge points, resulting in unstable break-ring torque, which affects the opening performance and use experience of the bottle caps. In addition, the wear of the cutting ring knife may also cause uneven bridge points, further affecting the torque performance.

[0003] For example, Chinese Patent CN219044554U discloses a plastic bottle cap with an internally formed bridge point, including a cap body, and an anti-theft ring is arranged at the bottom end of the cap body; an inner plug is arranged at the inner top of the cap body, an internal thread is arranged on the inner wall of the cap body, and a plurality of connecting bridges are evenly arranged at the bottom end of the inner wall of the cap body, and internally formed bridge points are arranged between adjacent connecting bridges, which ensures the sealing performance of the product and can effectively solve the problem of difficult opening of the bottle cap. However, in the specific application process of the above plastic bottle cap, there are the following deficiencies: First, the number of bridge points of the bottle cap is large, resulting in thin bridge points, and it is extremely easy to break the bridge during online filling, and the practicability is poor; in addition, the bridge points of the bottle cap are designed to be evenly distributed, which will cause "leakage first and then break" when opening the bottle cap. The bottle cap leaks air first before the bridge points are broken, so that the contents in the bottle may leak or be damaged in advance before the bottle cap is completely opened, resulting in the risk of food safety.

[0004] For the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0005] In view of the problems in the related art, the present utility model provides a bottle cap with regularly thick and thin bridge points to overcome the above technical problems existing in the related art.

[0006] To this end, the specific technical solution adopted by the present utility model is as follows:

[0007] A bottle cap with regularly thick and thin bridge points, including an annular body, a bridge point assembly is arranged inside the annular body, a plurality of dividing strips distributed in a circumferential manner are arranged at the bottom end of the annular body, an annular anti-theft ring is arranged at one end of the dividing strip, a smooth part is arranged on one side of the annular body, a plurality of friction strips distributed in a circumferential manner are arranged on the outer side of the annular body, and a sealing cap assembly is arranged at the top end of the annular body.

[0008] Furthermore, in order to achieve the width difference between the first bridge point and the second bridge point, so that the opening process not only ensures safety but also provides a good tactile experience, and forms a "break first and then leak" mechanism to ensure that the contents will not be contaminated or leaked before the bottle cap is fully opened, the bridge point assembly includes an inner plug sleeve sleeved on the inner side of the annular body. A number of fixing bumps distributed in a circumferential manner are arranged on the inner side of the inner plug sleeve, and ventilation grooves are formed between adjacent two groups of fixing bumps. Thread grooves are formed on the inner sides of the fixing bumps. A number of first bridge points distributed in a circumferential manner are arranged at the bottom end of the inner plug sleeve, and second bridge points are arranged between adjacent two groups of first bridge points. The number of the first bridge points is set to be [X], and the number of the second bridge points is set to be [Y]. The width of the first bridge point is greater than that of the second bridge point, and the height of the first bridge point is equal to that of the second bridge point.

[0009] Furthermore, in order to provide a part that is convenient for users to hold and operate, improve the comfort and convenience when opening the bottle cap, and enable users to open the bottle cap more easily and stably, the sealing cap assembly includes a sealing ring arranged at the top end of the annular body. A holding block is arranged on one side of the sealing ring. A cap body is arranged at the top end of the sealing ring. A circular clamping groove is formed at the top end of the cap body. An injection hole is arranged in the middle of the top end of the circular clamping groove. An opening protrusion is arranged on one side of the top end of the circular clamping groove. A number of anti-slip blocks distributed in a circumferential manner are arranged on the outer side of the cap body. An inclined surface is arranged at the top end of the anti-slip block. An arc part matching with the inclined surface is arranged at the top of the outer side of the cap body.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. The structure of the present utility model is scientific and novel. By adopting a thick and thin regular bridge point structure, the distribution of the bridge points is more uniform, the side surface of the bridge points is smoother without cutting burrs, and 8 thicker first bridge points are added on the basis of 8 thinner second bridge points, ensuring that the thick bridge points will not break when the thin bridge points break, better ensuring that the bottle mouth does not leak air, and the cap breaking ring experience is good, enabling consumers to unscrew it easily; at the same time, it effectively avoids the uneven cross-sectional area of the cut ring bridge points, is not easily affected by the cutting teeth and temperature of the cut ring knife, and avoids the problems of poor torque performance and breakage caused by the uneven cross-sectional area of the bridge points.

[0012] 2. By arranging the bridge point assembly, the width difference between the first bridge point and the second bridge point is achieved, so that the opening process not only ensures safety but also provides a good tactile experience, and forms a "break first and then leak" mechanism, ensuring the breaking ring torque performance of the bottle cap and ensuring that the contents will not be contaminated or leaked before the bottle cap is fully opened; at the same time, the breakage of the second bridge point provides an obvious visual hint indicating that the bottle cap has been opened. In addition, the unified height of the bridge points simplifies the manufacturing process, increases the service life of the cut ring knife, and the different width designs improve the functionality and safety of the bottle cap sealing without increasing the cost.

[0013] 3. By setting up the seal cover assembly, a part that is convenient for users to hold and operate is provided through the holding block, which increases the comfort and convenience when opening the bottle cap, helps users apply appropriate force when opening the bottle cap, and protects fingers from being injured at the same time. Meanwhile, the combined design of the anti-slip block and the arc part increases the friction and holding stability when the user opens the bottle cap. The cooperation of the inclined plane and the arc part enables the user to apply force more easily when rotating the bottle cap and provides a good feeling when opening the cap.

[0022] To further illustrate each embodiment, the present utility model provides accompanying drawings, which are a part of the disclosure of the present utility model. They are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0023] According to an embodiment of the present utility model, a bottle cap with regularly thick and thin bridge points is provided.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners. As Figures 1 - 5 shown, the bottle cap with regularly thick and thin bridge points according to an embodiment of the present utility model includes an annular body 1. A bridge point assembly 2 is provided inside the annular body 1. A plurality of dividing strips 3 distributed in a circular pattern are provided at the bottom end of the annular body 1. An annular anti-theft ring 4 is provided at one end of the dividing strip 3. A smooth portion 5 is provided on one side of the annular body 1. A plurality of friction strips 6 distributed in a circular pattern are provided on the outer side of the annular body 1. A sealing cap assembly 7 is provided at the top end of the annular body 1.

[0025] By virtue of the above technical solutions of the present utility model, the structure of the present utility model is scientific and novel. By adopting the regularly thick and thin bridge point structure, the distribution of the bridge points is more uniform, the side surface of the bridge points is smoother without cutting burrs, and 8 thicker first bridge points 205 are added on the basis of 8 thinner second bridge points 206, ensuring that when the thin bridge points break, the thick bridge points will not break, better ensuring that the bottle mouth does not leak air, and the bottle cap breaking ring experience is good, enabling consumers to easily unscrew it; at the same time, it effectively avoids the uneven cross-sectional area of the cutting ring bridge points, is not easily affected by the cutting ring tool teeth and temperature, and avoids the problems of poor torque performance and fracture caused by the uneven cross-sectional area of the bridge points.

[0026] In one embodiment, for the above-mentioned bridge point component 2, the bridge point component 2 includes an inner plug sleeve 201 sleeved inside the annular body 1 (in addition, in specific applications, the inner plug sleeve 201 is fixedly connected to the annular body 1). A number of fixing bumps 202 distributed in a circumferential manner are arranged inside the inner plug sleeve 201, and an air vent groove 203 is provided between two adjacent groups of fixing bumps 202. A threaded groove 204 is provided inside the fixing bump 202 (in addition, in specific applications, the threaded groove 204 is matched with the external thread of the bottle mouth to realize the sealing of the bottle cap to the bottle mouth). A number of first bridge points 205 distributed in a circumferential manner are arranged at the bottom end of the inner plug sleeve 201, and a second bridge point 206 is arranged between two adjacent groups of first bridge points 205. The number of the first bridge points 205 is set to 8, and the number of the second bridge points 206 is set to 8. The width of the first bridge point 205 is greater than the width of the second bridge point 206, and the height of the first bridge point 205 is equal to the height of the second bridge point 206. Thus, through the width difference between the first bridge point 205 and the second bridge point 206, the opening process not only ensures safety but also provides a good hand feeling experience, and forms a "break first and then leak" mechanism, ensuring that the content will not be contaminated or leaked before the bottle cap is completely opened.

[0027] In addition, in specific applications, the width of the inner-formed thick bridge point (the first bridge point 205) is 3.0 mm, the height of the inner-formed thick bridge point (the first bridge point 205) is 0.5 mm, the width of the inner-formed thin bridge point (the second bridge point 206) is 0.43 mm, and the height of the inner-formed thin bridge point (the second bridge point 206) is 0.5 mm. By using the regular bridge points of one thick and one thin, when unscrewing the cap, the thin bridge point breaks first. The thin bridge point serves as evidence for opening the bottle cap, ensuring food safety. Then the thick bridge point breaks to bear the force, enabling the purchaser to have a better hand feeling experience.

[0028] The working principle of the bridge point component 2 is as follows: The inner plug sleeve 201, as the basic part of the bridge point component, is sleeved inside the annular body 1, providing a framework for the installation and support of the bridge points, capable of maintaining the overall structure of the bottle cap and playing a role in transmitting force during the opening process. The fixing bumps 202 are distributed in a circumferential manner, increasing the friction between the inner plug sleeve 201 and the bottle mouth and preventing the bottle mouth from shifting during sealing. The design of the air vent groove 203 allows gas to gradually leak when the bottle cap is opened, helping to control the gas release speed and avoiding inconvenience to the user caused by sudden pressure release. The threaded groove 204 is used to cooperate with the bottle mouth to enhance the sealing performance of the bottle cap and ensure the safety of the object inside the bottle. Through the matching of the threaded groove 204 and the bottle mouth thread, better rotational cooperation can be provided when opening and closing the bottle cap, making the operation smoother.

[0029] The settings of the first bridge point 205 and the second bridge point 206 are the key to this design. They have different widths but equal heights. Such a design achieves the following functions: First, it provides a break-before-leak mechanism. When opening the bottle cap, the thinner second bridge point 206 breaks first as the initial action of opening, and then the wider first bridge point 205 breaks to bear the main opening force. Second, it realizes the retention of opening evidence. The breakage of the second bridge point 206 leaves an obvious opening mark as evidence that the bottle cap has been opened, which helps prevent the replacement of the object inside the bottle and ensures food safety. Moreover, it increases the service life of the cutting ring knife, ensuring both the product's sealing performance and its break-ring torque performance.

[0030] In one embodiment, for the above-mentioned seal cap assembly 7, the seal cap assembly 7 includes a sealing ring 701 provided at the top end of the annular body 1 (in addition, in specific applications, the annular body 1 is fixedly connected to the cap body 703 through the sealing ring 701). A holding block 702 is provided on one side of the sealing ring 701. A cap body 703 is provided at the top end of the sealing ring 701. A circular clamping groove 704 is provided at the top end of the cap body 703. An injection hole 705 is provided in the middle of the top end of the circular clamping groove 704. An opening bump 706 is provided on one side of the top end of the circular clamping groove 704 (in addition, in specific applications, the cross-section of the opening bump 706 is set as a trapezoidal structure). A number of anti-slip blocks 707 distributed in a circumferential manner are provided on the outer side of the cap body 703. The top end of the anti-slip block 707 is provided with an inclined surface. An arc portion 708 matching the inclined surface is provided at the top of the outer side of the cap body 703, thus providing a part convenient for the user to hold and operate, increasing the comfort and convenience when opening the bottle cap, and enabling the user to open the bottle cap more easily and stably.

[0031] The working principle of the sealing cap assembly 7 is as follows: The sealing ring 701 is the core part for connecting the sealing cap assembly 7 and the annular body 1. Its function is to ensure the fixed connection between the sealing cap assembly 7 and the annular body 1, prevent the leakage of the contents or the entry of external pollutants. The holding block 702 provides a part for the user to hold and operate conveniently, increasing the comfort and convenience when opening the bottle cap. Its design helps the user apply appropriate force when opening the bottle cap while protecting the fingers from being hurt. The cap body 703 is the part above the sealing ring 701. A sealing cavity is formed by the inner side of the cap body 703 and the top end of the annular body 1. When the bottle cap seals the bottle mouth, it is used to accommodate the end of the bottle mouth and form a closed space. The circular clamping groove 704 is used to cooperate with the structure of the bottle mouth after removing the bottle cap, facilitating the user to invert and press the bottle cap on the bottle mouth after opening the bottle cap. The injection hole 705 is a hole used for injection molding during the manufacturing process of the bottle cap, which helps to improve the production efficiency and product quality of the bottle cap. After the bottle cap is formed, the injection hole 705 is closed to ensure the sealing performance of the bottle cap. The bottle-opening convex block 706 is a component used to assist in opening the bottle cap. After inverting the opened bottle cap on the bottle mouth, the user can apply force by pressing the bottle cap. The acute angle of the trapezoidal structure of the bottle-opening convex block 706 cuts open the plastic seal of the bottle mouth, making the opening process easier. The combined design of the anti-slip block 707 and the arc part 708 increases the friction force and the holding stability when the user opens the bottle cap. The cooperation of the inclined plane and the arc part enables the user to apply force more easily when rotating the bottle cap, while providing a good hand feeling.

[0032] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0033] In actual application, the annular body 1 serves as the basic structure of the bottle cap. The bridge point assembly 2 is arranged inside it. During the opening process, the bridge point assembly 2 plays a role in retaining the opening evidence and also ensures the sealing performance. The dividing strip 3 enhances the overall structural strength of the bottle cap and also helps in the molding process during manufacturing. The annular anti-theft ring 4 provides an additional anti-theft function to prevent unauthorized opening of the bottle cap. The smooth part 5 provides a comfortable hand-holding feeling and protects the user from being hurt when opening the bottle cap. The friction strip 6 increases the friction force during holding and improves the stability during opening. The sealing cap assembly 7 ensures the sealing performance between the bottle cap and the bottle mouth, preventing the leakage of the contents or the entry of external pollutants. For example, the height of the annular anti-theft ring is 2 mm and the radius of the bottle mouth is 0.8 mm. When the bottle cap is opened and axially rises (2.0 - 0.8 = 1.2) 1.2 mm, air leakage occurs. At this time, the second bridge point 206 is designed to break the bridge when the lid is opened 0.8 mm, serving the purpose of retaining the opening evidence and also ensuring the sealing performance.
