[0037] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0040] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a bottle cap structure, which includes a mouth tube assembly 1 and a mouth tube cap assembly 2. With the cooperation of the mouth tube assembly 1, the bottle cap and the anti-theft ring 23-2 on the bottle mouth are not easily separated, so that the bottle cap will not be discarded at will, reducing the difficulty of recycling. In daily use, the bottle cap will not be placed casually by the user, making it easy to find.

[0041] Specifically, the mouth tube assembly 1 includes a mouth tube 11, with a thread 12 fixedly connected to the upper surface of the mouth tube 11 and a stop block 13 fixedly connected to the outer surface of the mouth tube 11. The thread 12 engages with the locking thread 22 on the cover 21 to thread the cover 21 onto the mouth tube 11. There are four stops 13, each with an arc surface. During installation, when the cover 21 is fitted onto the mouth tube 11 and rotates to rotate the pawl 24, the pawl 24 can rotate over the stops 13 by means of the arc surface.

[0042] Specifically, the nozzle cap assembly 2 is fitted onto the surface of the nozzle 11, including a cap 21 fitted onto the upper end of the nozzle 11. The inner wall of the cap 21 is fixedly connected with a locking thread 22, which engages with a thread 12. Both the thread 12 and the locking thread 22 are intermittent. With this design, it is easier to tighten the nozzle cap assembly 2 when it is rotated to connect with the nozzle assembly 1.

[0043] An anti-theft component 23 is fixedly connected to the lower end of the cover 21. A claw 24 is fixedly connected to the inner wall of the anti-theft component 23, and it cooperates with the stop block 13. With the setting of the anti-theft component 23, when it is unscrewed and rotated, the stop block 13 blocks the anti-theft component 23 to form a relative movement that pulls the connection point apart. The anti-theft component 23 is opened, and the seal is opened.

[0044] Example 2 Reference Figures 2-6 This is the second embodiment of the present invention, which is based on embodiment 1.

[0045] Specifically, the anti-theft component 23 includes a connecting rib 23-1 fixedly connected to the cover 21. The anti-theft ring 23-2 is connected to the cover 21 as a whole through the connecting rib 23-1, which is environmentally friendly. The anti-theft ring 23-2 is fixedly connected to the connecting rib 23-1. With the setting of the anti-theft ring 23-2, when the cover 21 is rotated, the cover 21 is rotated upward under the cooperation of the screw thread 12 and the locking thread 22, so that the claw 24 on the anti-theft ring 23-2 is blocked by the stop block 13 on the mouth tube 11.

[0046] The anti-theft ring 23-2 is provided with a longitudinal connection point 23-3 and a transverse connection point 23-4. By setting the longitudinal connection point 23-3 and the transverse connection point 23-4, the cover 21 is rotated and moved upward. After the claw 24 on the anti-theft ring 23-2 is blocked by the stop block 13 on the mouth tube 11, the longitudinal connection point 23-3 and the transverse connection point 23-4 are pulled apart. The anti-theft ring 23-2 is connected to the cover 21 and detached from the mouth tube 11 through the connecting rib 23-1.

[0047] The inner wall of the cover 21 is fixedly connected with a first sealing rib 25, which is distributed in a circumferential array. There are several first sealing ribs 25. Through the setting of the first sealing ribs 25 and the second sealing ribs 26, the first sealing ribs 25 and the second sealing ribs 26 are fixed by the wall of the tube 11 in two directions. Even if the tube 11 is deformed into an ellipse, it can be adjusted back to a circle to form a reliable seal.

[0048] The top of the inner wall of the cover 21 is fixedly connected with a second sealing rib 26 and a third sealing rib 27, which respectively cooperate with the upper end of the inlet tube 11. The third sealing rib 27 forms a double seal, making the seal more reliable.

[0049] Three connecting plates 14 are fixedly connected to the outer surface of the nozzle 11. These plates are all fixedly fitted onto the outer surface of the nozzle 11, allowing for easy gripping and rotation of the cap 21. The spacing between the connecting plates 14 saves material and does not affect normal use. A connector 15 is fixedly connected to the lower end of the nozzle 11. The connector 15 facilitates connection to the bag during the production of fluid-filled bags. A welding seam 15-1 is provided at the upper end of the connector 15, preventing edge curling and ensuring a stronger weld. An R-angle 15-2 is provided on the outer surface of the connector 15, preventing the packaging bag from slipping open. Weight-reduction holes 15-3 are provided on the connector 15, allowing for weight reduction and minimizing material usage.

[0050] When in use, when the cover 21 is tightened, the third sealing rib 27 presses against the inlet tube 11 to form a seal, and the second sealing rib 26 is press-fitted with the inner wall of the inlet tube 11 to form a seal. The connecting rib 23-1 connects the anti-theft ring 23-2 to the cover 21 as one unit, which is environmentally friendly. The first sealing rib 25 limits the inlet tube 11, and the second sealing rib 26 provides a more reliable seal. The intermittent threads make it easier to tighten. When unscrewing and rotating, the stop block 13 blocks the anti-theft ring 23-2 to form relative movement and pull the connection point apart. This reduces the amount of glue used and the weight is reduced. Once the anti-theft ring 23-2 is opened, the package is already unsealed.

[0051] Example 3 Reference Figures 2-6 This is the third embodiment of the present invention, which is based on embodiment 2.

[0052] Specifically, the outer surface of the cover 21 is fixedly connected with anti-slip ribs 28 and reinforcing ribs 29 respectively. Three reinforcing ribs 29 form a group. One cover 21 is provided with three anti-slip ribs 28 and three groups of reinforcing ribs 29. By setting the anti-slip ribs 28, the friction between the hands is increased when rotating the cover 21, making it easier to rotate and remove the cover 21. The protruding anti-slip ribs 28 increase the friction and torque, making it easier to unscrew. By setting the reinforcing ribs 29, the strength of the cover 21 is increased, making it less prone to deformation under force.

[0053] Example 4 Reference Figures 7-9 This is the fourth embodiment of the present invention, which is based on embodiment 2.

[0054] Specifically, anti-slip ribs 28 and reinforcing ribs 29 are fixedly connected to the outer surface of the cover 21. Three reinforcing ribs 29 form a group, and four anti-slip ribs 28 are provided on one cover 21, and four groups of reinforcing ribs 29 are provided on one cover 21. Specifically, Example 5 Reference Figures 10-12 This is the fifth embodiment of the present invention, which is based on embodiment 2.

[0055] Specifically, anti-slip ribs 28 and reinforcing ribs 29 are fixedly connected to the outer surface of the cover 21. Three reinforcing ribs 29 form a group, and five anti-slip ribs 28 are provided on one cover 21, and five groups of reinforcing ribs 29 are provided on one cover 21.

[0056] Example 6 Reference Figures 13-15 This is the sixth embodiment of the present invention, which is based on embodiment 2.

[0057] Specifically, a ring 210 is fixedly connected to the outer surface of the cover 21. There is a movable gap between the surface of the ring 210 and the outer surface of the cover 21. When it is squeezed, its deformation can protect the cover 21. The outer surface of the ring 210 is provided with anti-slip texture 211. A first connecting block 212 is fixedly connected to the upper end of the cover 21.

[0058] The anti-slip texture 211 consists of several pieces arranged in a circular array on the outer surface of the ring 210. By setting the anti-slip texture 211, the friction between the hand and the ring 210 is increased when rotating the cover 21, reducing the slippage when turning the cover 21. The upper end of the cover 21 is reinforced by setting the first connecting block 212.

[0059] Example 7 Reference Figures 16-18 This is the seventh embodiment of the present invention, which is based on embodiment 2.

[0060] Specifically, a ring 210 is fixedly connected to the outer surface of the cover 21, and the outer surface of the ring 210 is provided with anti-slip texture 211. A second connecting block 213 is fixedly connected to the cover 21. The upper end of the cover 21 is reinforced by the setting of the first connecting block 212.

[0061] In summary, with the cooperation of the mouthpiece assembly 1 and the mouthpiece cap assembly 2, the bottle cap and the anti-theft ring 23-2 on the bottle mouth are not easily separated, so the bottle cap will not be discarded at will. Compared with the existing technology, it reduces the difficulty of recycling. In daily use, the bottle cap will not be placed by the user and will be easy to find, which increases the convenience of use. In addition, the mouthpiece cap on the mouthpiece bag is easier to twist, reducing the probability of children being unable to twist it open.
