[0033] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0034] Please see Figure 1-4 This embodiment provides a breathable bottle cap for covering an annular bottle body 1, wherein the outer wall of the bottle body 1 has external threads 11, and the breathable bottle cap includes:

[0035] The cap 2 has an internal thread 21 on its inner wall that matches the size and position of the external thread 11. The side of the cap 2 facing the bottle mouth of the bottle body 1 forms a receiving groove 22. The cap 2 has a through hole 24 in the receiving groove 22.

[0036] Breathable pad 3, the breathable pad 3 is installed in the receiving groove 22, and the outer surface of the breathable pad 3 is provided with a polytetrafluoroethylene coating;

[0037] Anti-theft ring 4 is provided at the end of the cap 2. The inner wall of the anti-theft ring 4 is provided with a locking tooth 41, and the outer wall of the bottle 1 is provided with an abutment part 12 for limiting the rotation of the locking tooth 41.

[0038] Based on the above structure, during installation, the cover 2 and the vent gasket 3 of the main body can be manufactured separately. In one embodiment, the cover 2 can be configured as an integrally molded structure connected to the anti-theft ring 4, by cutting the cover 2 and the anti-theft ring 4 to form a structure that is easy to tear apart. After they are manufactured separately, the vent gasket 3 can be installed vertically in the receiving groove 22 of the cover 2, thus forming a relatively sealed structure.

[0039] When installed, the receiving groove 22 faces the bottle opening of the bottle body 1. In other words, the venting pad 3 faces the direction of the bottle body 1 directly. Therefore, the gas in the direction of the bottle body 1 can pass through the venting pad 3 on the receiving groove 1 to the through hole 24 of the receiving groove 1 and escape from the cap 2 to the outside of the bottle body 1.

[0040] Furthermore, in one embodiment, the breathable gasket 3 with a polytetrafluoroethylene (PTFE) coating, based on its microporous structure and surface chemical properties, allows only gas to pass through while water is restricted by the waterproof and breathable membrane formed by the PTFE coating, thus achieving breathability. Specifically, the pore size range of the breathable gasket 3 is controlled within a preset range. Liquid water molecules will form spherical water droplets due to surface tension, preventing them from passing through the micropores. Even when pressure is applied, the surface tension of water prevents its penetration, achieving a good waterproof effect. Of course, multilayer composite gaskets, such as those used in authorized patent CN 220576796 U, can also be used as an optional replacement for the breathable gasket 3.

[0041] The outer surface of the breathable pad 3 can refer to the upper and lower surfaces of the breathable pad 3. The base material layer of the breathable pad 3 itself can be made of a rigid material.

[0042] In this embodiment, when needed, the operator can rotate the cap 2, causing the external thread 11 and internal thread 21 to move in an alternating manner, so that the cap 2 moves away from the bottle body 1. Therefore, since the end of the cap 2 is connected to the anti-theft ring 4, and the locking teeth 41 of the anti-theft ring 4 are engaged in the abutment part 12 of the bottle body 1, the anti-theft ring 4 can be pulled apart from the cap 2 during the movement of the cap 1. After the cap 2 is separated, the anti-theft ring 4 remains on the bottle body 1, so it can be seen intuitively whether the cap 2 has been opened, which has a more conspicuous anti-theft effect.

[0043] In this embodiment, a receiving groove 22 for installing the breathable gasket 3 can be formed on the bottle cap 2. The breathable gasket 3 can block water and achieve a breathable effect, avoiding the influence of high pressure in the bottle. Specifically, the breathable gasket 3 is provided with a polytetrafluoroethylene coating, which can form a waterproof and breathable membrane. With the help of the gasket's own microporous structure and surface chemical properties, it can achieve air permeability but not water permeability. Therefore, under extreme temperature changes, the pressure inside the bottle can be controlled. At the same time, due to the setting of the receiving groove 22, the snap-fit ​​installation method is easy to install and has a low cost.

[0044] In another embodiment, the receiving groove 22 protrudes axially toward the bottle body 1. For example... Figure 1 As shown, the receiving groove 22 can be an annular structure that protrudes downwards from the bottom surface of the bottle body 1. The inner diameter of the receiving groove 22 narrows towards the bottle body 1 so that the vent gasket 3 can be engaged in the receiving groove 22. Specifically, the vent gasket 3 in Figure 1 The middle part near the bottom is more breathable than the 3rd layer. Figure 1 The inner diameter of the part near the through hole 24 is smaller, thus forming a limit space that is approximately trapezoidal. The breathable gasket 3 itself has a certain elasticity, which allows the breathable gasket 3 to deform slightly after installation and be tightly snapped into the receiving groove 22.

[0045] In another embodiment, the thickness of the breathable pad 3 is equal to the depth of the receiving groove 22. That is, the breathable pad 3 can just fill the receiving groove 22, or leave only a small gap, so that the breathable pad 3 itself is installed more stably in the receiving groove 22, preventing it from falling off due to bumps.

[0046] See also Figure 3 The outer diameter of the receiving groove 22 is less than half the outer diameter of the cap 2. In other words, the size of the receiving groove 22 and the venting gasket 3 occupies only a very small space on the bottle body 1, which helps to control costs and reduce the weight of the venting gasket 3 itself, preventing it from falling off.

[0047] Furthermore, the receiving groove 22 is located in the middle of the cap 2. The through hole 24 is located in the middle of the receiving groove 22. Therefore, when gas is generated inside the bottle 1, it can be emitted more evenly from the top of the bottle 1. Its central location, with the breathable gasket 3 and the through hole 24 having uniform dimensions, provides stronger gas exchange capacity.

[0048] In another embodiment, please refer to Figure 2 The outer wall of the cover is provided with raised anti-slip ridges 23, which extend in the direction in which the cover 2 is detached. In this embodiment, the number of anti-slip ridges 23 is set to four, and the width of each anti-slip ridge 23 is set to 3mm. Compared with the anti-slip ridges provided on a typical cover, the number of anti-slip ridges 23 in this embodiment is smaller and the thickness is greater, which is suitable for the design of larger-sized cover 2, and the mold opening cost is lower and it is easy to produce.

[0049] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.
