[0014] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0015] According to an embodiment of the present invention, a disposable bottled water anti-tamper soft and hard rubber inner plug sealing screw cap is provided.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-2As shown, the disposable bottled water anti-tampering soft and hard rubber inner plug sealing cap according to an embodiment of this utility model includes a cap body 1, a three-pronged thread 2, an anti-theft ring 3, anti-slip teeth 4, an anti-theft ring cutout 5, and a sealing inner plug 6. The anti-theft ring 3 is connected to the bottom of the cap body 1, the anti-theft ring cutout 5 is opened between the anti-theft ring 3 and the cap body 1, the three-pronged thread 2 is provided on the inner wall of the cap body 1 for tightening with the bottle opening, the anti-slip teeth 4 are distributed on the inner side of the anti-theft ring 3, and the sealing inner plug 6 is provided on the lower end face of the cap body 1. The sealing inner plug 6 includes a hard rubber layer 61 and a soft rubber layer 62. The hard rubber layer 61 has an annular structure, and its outer side is fixedly connected to the inner wall of the cap body 1. The soft rubber layer 62 fills the annular cavity of the hard rubber layer 61, and the bottom of the soft rubber layer 62 extends out of the bottom of the hard rubber layer 61 to form a sealing plug 6 for insertion into the bottled water interface.

[0017] In one embodiment, the pitch of the three-threaded cap 2 is 4.0 mm, and the thread structure is adapted to the internal thread of the disposable bottled water bottle opening. This ensures a tight connection between the cap and the bottle opening, preventing it from loosening.

[0018] In one embodiment, the anti-theft ring 3 is integrally formed with the lower part of the cap body 1, and the anti-slip teeth 4 are evenly distributed around the anti-theft ring 3 by injection molding.

[0019] In one embodiment, the soft rubber layer 62 is made of food-grade silicone rubber, and the soft rubber layer 62 is provided with a groove 621, which engages with the barrel opening wall. It provides an interference fit with the raised structure of the barrel opening wall, enhancing the sealing effect.

[0020] In one embodiment, the anti-theft ring cut 5 is a V-shaped groove structure with intervals, and the groove depth is 2 / 3 of the thickness of the joint between the anti-theft ring 3 and the cap body 1. This ensures that the anti-theft ring 3 can break off along the cut when the cap is opened.

[0021] In one embodiment, the anti-slip teeth 4 are wedge-shaped structures, with their inclination direction opposite to the tightening direction of the cap body 1. When tightened, the anti-slip teeth 4 fit against the outer wall of the barrel opening, preventing the cap from loosening and enhancing the anti-disassembly effect.

[0022] Working principle: Align the cap body 1 with the opening of the bottled water container, and tighten it by engaging the three-pronged thread 2 on the inner wall with the external thread of the opening. Since the pitch of the three-pronged thread 2 is 4.0mm, it reduces the number of turns by 2 / 3 compared to traditional single-pronged threads, quickly completing the sealing process. During tightening, the anti-slip teeth 4 on the inner side of the anti-theft ring 3 fit against the outer wall of the opening. Because the wedge-shaped structure's tilt direction is opposite to the tightening direction, it prevents the cap from loosening. The soft rubber layer 62 of the sealing inner plug 6 is inserted into the opening, and the groove 621 fits the protrusion on the opening wall with an interference fit. Combined with the elasticity of food-grade silicone rubber, a tight seal is achieved. The hard rubber layer 61 ensures the overall structural stability of the inner plug, preventing deformation. When the cap needs to be opened, screw on the cap body 1. The V-shaped groove at the anti-theft ring cut 5 breaks due to the force, separating the anti-theft ring 3 from the cap body 1 and leaving it on the opening, forming a clear anti-tamper mark, allowing for direct identification of whether the container has been opened.
