Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to an openable bottle cap. Background Technology

[0002] With the continuous improvement of people's living standards and the increasing demands for convenience and hygiene, various packaging containers are being used more and more widely in daily life. As a key component for sealing the bottle body, the structural design of the bottle cap directly affects the user experience, sealing performance, and safety of the product.

[0003] In recent years, hinged bottle caps have gradually gained market favor due to their ease of opening and intuitive operation. These caps typically consist of a mounting base fixed to the bottle and a flip-top cap, allowing for easy opening and closing of the bottle opening with a simple flipping motion, making them particularly suitable for one-handed operation. However, existing hinged bottle caps still have some problems in practical applications:

[0004] 1. Insufficient installation reliability: The connection between some openable bottle caps and the bottle body is not secure enough, and they are prone to loosening or even falling off during use, affecting the sealing effect and user experience. In particular, when the bottle body is squeezed or impacted, the mounting bracket may detach from the bottle mouth, leading to leakage.

[0005] 2. Opening and closing cap springback issue: When the user opens the bottle cap, the cap may automatically spring back to the closed position under the action of spring or other elastic elements, especially when the opening angle is large. This springback phenomenon not only affects the convenience of use, but may also pose certain safety hazards.

[0006] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0007] This invention overcomes the shortcomings of the prior art and provides a simple, reliable, easy-to-operate, and effective anti-rebound bottle cap.

[0008] This utility model is achieved through the following technical solution:

[0009] A closing bottle cap includes a mounting base for connecting a bottle body, the mounting base having a mounting hole for inserting a bottle mouth, and a closing cap for opening and closing the bottle mouth rotatably connected to the mounting base. A locking block extending inward and capable of preventing the mounting base from disengaging from the bottle mouth after the bottle mouth is inserted into the mounting hole is rotatably connected to the lower part of the mounting base. The lower part of the closing cap has a limiting structure that can prevent the closing cap from springing back when its opening angle is greater than a preset angle.

[0010] As described above, in a type of closing bottle cap, the limiting structure includes a locking block connected to the lower part of the closing cap and capable of rotating with it. When the opening angle of the closing cap is greater than a preset angle, the outer wall of the locking block rotates to the inner side and abuts against the outer wall of the bottle mouth.

[0011] As described above, in a type of openable bottle cap, flexible connecting strips are provided on the left and right sides of the locking block. One end of the flexible connecting strip is connected to the locking block, and the other end is connected to the mounting base.

[0012] As described above, in a type of openable bottle cap, the flexible connecting strip and the mounting base are provided with a first tearing structure that can be torn when the external force for opening the cap is greater than a first preset value.

[0013] As described above, in a type of openable bottle cap, the locking block has a pre-installation state and a post-installation state. When the locking block is in the pre-installation state, it extends downward and inward. When the locking block is in the post-installation state, it extends upward and inward. The locking block is clamped between the bottle mouth and the inner wall of the mounting base.

[0014] As described above, in one type of openable bottle cap, the lower part of the mounting base is connected to at least two locking blocks, which are evenly distributed circumferentially.

[0015] As described above, the opening and closing bottle cap has a post at the bottom that can extend into the bottle opening.

[0016] As described above, in one type of clasp-type bottle cap, the lower surface of the cap has a mounting groove corresponding to the position of the insertion post, and a decorative block is provided in the mounting groove.

[0017] As described above, in a type of openable bottle cap, a second tearing structure is provided between the cap and the mounting base, which can be torn when the external force for opening the cap is greater than a second preset value.

[0018] As described above, in a type of openable bottle cap, the mounting base is formed by bending a disassembly strip into an arc shape. The disassembly strip is provided with a connecting part that connects its ends. A first tearing part that can be torn when the external force is greater than a third preset value is provided between the connecting part and the disassembly strip. A second tearing part that can be torn when the external force is greater than a fourth preset value is provided between the disassembly strip and the openable cap.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention features a rotatable locking block at the bottom of the mounting base. When the bottle nozzle is inserted into the mounting hole, the locking block extends inward and locks the base of the nozzle or the shoulder of the bottle, creating a mechanical limit. This design effectively prevents the mounting base from accidentally detaching from the nozzle due to external force during use, significantly improving the reliability and sealing stability of the connection between the cap and the bottle body, and avoiding liquid leakage.

[0021] The limiting structure at the bottom of the lid automatically activates when the opening angle exceeds a preset angle, preventing the lid from springing back under the action of the elastic connector. This prevents the lid from closing suddenly and also allows users to keep it open without having to exert continuous force when pouring or drinking.

[0022] The locking block and the limiting structure are integrated into the mounting base and the opening / closing cap respectively, making full use of the internal space of the bottle cap, resulting in a compact and reasonable overall structure. The locking block prevents the cap from detaching during installation, while the limiting structure prevents the cap from springing back when opened. The two functions are independent yet work together to improve the overall performance of the bottle cap. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1 to 6The illustrated bottle cap includes a mounting base 1 for connecting a bottle body 100. The mounting base 1 has a mounting hole 10 for inserting a bottle nozzle 101. A hinged cap 2 for opening and closing the bottle nozzle 101 is rotatably connected to the mounting base 1. A locking block 3, extending inwards and preventing the mounting base 1 from disengaging from the bottle nozzle after the bottle nozzle 101 is inserted into the mounting hole 10, is rotatably connected to the lower part of the mounting base 1. A limiting structure 4, located at the lower part of the hinged cap 2, prevents the cap from springing back when its opening angle exceeds a preset angle. The outer wall of the bottle nozzle 101 typically has a groove 102 or a locking block. After the bottle cap is installed, the locking block 3 is inserted obliquely upwards into the groove 102, with its edge pressing against the side wall of the groove 102, thereby preventing the mounting base 1 from disengaging.

[0033] This utility model features a rotatable locking block 3 at the lower part of the mounting base 1. When the bottle nozzle 101 is inserted into the mounting hole 10, the locking block 3 locks the root of the bottle nozzle 101 or the slot 102 inward, forming a mechanical limit and effectively preventing the mounting base 1 from accidentally falling off, thus improving connection reliability and sealing. At the same time, a limiting structure is provided at the lower part of the opening and closing cap 2. When the opening angle exceeds the preset value, it automatically limits the opening and closing, preventing it from springing back and closing under the action of the elastic connector, thus facilitating the pouring operation. The locking block 3 and the limiting structure 4 are integrated into the mounting base 1 and the opening and closing cap 2, respectively. The structure is compact, the functions are independent and coordinated, and the overall performance of the bottle cap is significantly improved.

[0034] Furthermore, the limiting structure 4 includes a locking block connected to the lower part of the opening and closing cover 2 and capable of rotating with it. When the opening angle of the opening and closing cover 2 is greater than a preset angle, the outer wall of the locking block rotates to the inner side and abuts against the outer wall of the bottle mouth. Flexible connecting strips 11 are provided on the left and right sides of the locking block. One end of the flexible connecting strip 11 is connected to the locking block, and the other end is connected to the mounting base 1.

[0035] The limiting structure 4 uses a locking block that is linked to the opening and closing cap 2. When the opening angle of the opening and closing cap 2 exceeds the preset value, the locking block swings upward, and its outer side becomes the inner side and just abuts against the outer wall of the bottle mouth 101. It can accurately trigger the limiting function when the opening and closing cap 2 reaches a specific opening angle, effectively preventing rebound.

[0036] The locking block is connected to the mounting base 1 via a flexible connecting strip 11. The flexible connecting strip 11 has a certain deformation capacity, allowing the locking block to rotate through the dead point to the position triggering the limit function. It also provides a reset base for the locking block. When the user needs to close the opening / closing cap 2, the locking block is allowed to disengage from the nozzle 101, allowing the opening / closing cap 2 to rotate smoothly and close. The entire process requires no additional unlocking action, resulting in smooth and natural operation. The flexible connecting strip 11 can be integrally injection molded with the mounting base 1 and / or the opening / closing cap 2, significantly reducing the number of independent parts, simplifying the assembly process, lowering mold complexity and production costs, and facilitating large-scale production.

[0037] Furthermore, a first tear structure 12 is provided between the flexible connecting strip 11 and the mounting base 1, which can be torn when the external force for opening the cap exceeds a first preset value. The first tear structure 12 is torn upon first opening with a normal or slightly greater external force, and this change is irreversible. Therefore, this structure can serve as a one-time opening indicator. Consumers can determine whether the bottle cap has been opened by observing whether the first tear structure 12 is intact, effectively preventing the product from being switched or contaminated, and enhancing the safety and reliability of the product. The first tear structure 12 can be an easily torn thin-walled structure, a point-hole weakening line, or a fracture protrusion.

[0038] The locking block 3 has a pre-installation state and a post-installation state, that is, the state when the bottle cap is not installed and the state after installation. When the locking block 3 is in the pre-installation state, the locking block 3 extends downward and inward. When the locking block 3 is in the post-installation state, the locking block 3 extends upward and inward. The locking block 3 is clamped between the bottle mouth and the inner wall of the mounting base 1.

[0039] In one embodiment, at least two locking blocks 3 are connected to the lower part of the mounting base 1, and the locking blocks 3 are evenly distributed circumferentially. The preferred embodiment has three locking blocks 3 at the lower part of the mounting base 3.

[0040] In one embodiment, the lower part of the opening and closing cap 2 is provided with a post 21 that can extend into the bottle mouth. After the post 21 is inserted into the bottle mouth, it can effectively suppress slight shaking or vibration of the opening and closing cap 2 on the mounting base 1, thereby improving the stability of the overall structure and the durability of the seal. At the same time, it also improves the stress resistance of the bottle cap, and the bottle mouth 101 can also support the bottle cap, making it less likely to be flattened or deformed.

[0041] Furthermore, the lower surface of the cap 2 is provided with a mounting groove 22 corresponding to the position of the insert 21, and a decorative block 5 is provided within the mounting groove 22. The decorative block 5 can be made of a material with a different color, material, or texture than the main body of the cap, creating a visual contrast, adding a sense of refinement and design detail to the product, and significantly enhancing the overall appearance. Brand logos, text, patterns, or specific symbols can also be embossed, engraved, or injection molded onto its surface. This embedded logo is not easily worn or counterfeited, effectively strengthening the brand image and enhancing consumers' brand awareness and memory. At the same time, different product series can use decorative blocks of different colors or patterns to achieve visual differentiation of product lines. Of course, it is also possible not to place the decorative block 5 within the mounting groove 22.

[0042] In one embodiment, a second tear structure 23 is provided between the opening / closing cap 2 and the mounting base 1, which can be torn when the external force for opening the cap exceeds a second preset value. Consumers can determine whether the bottle cap has been opened by observing whether the second tear structure 23 is intact, effectively preventing the product from being switched or contaminated, and enhancing the safety and reliability of the product. The second tear structure 23 can be an easily torn thin wall, a point-hole weakening line, or an abnormal break protrusion.

[0043] like Figure 7 As shown, in one embodiment, the mounting base 1 is formed by bending a disassembly strip 13 into an arc shape. The disassembly strip 13 has a connecting portion 131 that connects its ends. A first tearing portion 132, which can be torn when the external force exceeds a third preset value, is provided between the connecting portion 131 and the disassembly strip 13. A second tearing portion 133, which can be torn when the external force exceeds a fourth preset value, is provided between the disassembly strip 13 and the opening / closing cap 2. The first tearing portion 132 and the second tearing portion 133 can be easily torn thin walls, point hole weakening lines, or fracture protrusions. The bottle cap can be removed from the bottle mouth 101 by breaking the first tearing portion 132 and the second tearing portion 133, thus facilitating the recycling of the bottle cap.
