[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] See also Figure 1-Figure 3 As shown, the utility model provides a bottle cap that will not be lost, including a bottle body 1, a bottleneck 2 is integrally formed at the upper end of the bottle body 1, an inner cover 3 is detachably connected to the bottleneck 2 through a first threaded structure, the inner cover 3 has the same outer diameter as the bottleneck 2, and the upper end surface of the inner cover 3 is an outwardly convex end plate, two through holes 5 are provided at the upper end of the side wall of the inner cover 3, the inner cover 3 and the bottleneck 2 are sleeved with the same outer cover 4, the outer cover 4 is annular in design, and the outer cover 4 is adjusted and moved along the axial direction of the inner cover 3 and the bottleneck 2 outside through a second threaded structure.

[0024] As an optional implementation, the first threaded structure includes a docking ring groove 6 opened at the upper end of the inner neck 2, and the lower end of the inner cover 3 is integrally formed with a threaded ring 7 that is threadably adapted to the docking ring groove 6. The inner cover 3 can be rotated to dock the threaded ring 7 with the docking ring groove 6 to achieve installation of the inner cover 3 on the upper end of the neck 2. It is worth mentioning that the connection between the inner cover 3 and the neck 2 can also be fixed by interference fit and plug-in.

[0025] Furthermore, the inner diameters of the inner cover 3, the threaded ring 7 and the bottleneck 2 are the same, and a sealing ring that abuts against the threaded ring 7 is provided at the inner bottom of the docking ring groove 6. The design of the same inner diameter can make the liquid flow more smoothly and avoid liquid accumulation at the joint. The sealing ring can prevent the internal liquid from leaking from the joint.

[0026] Reference Figure 2As shown, a docking ring seat 14 is integrally formed at the upper end of the side wall of the inner cover 3. The docking ring seat 14 is truncated and the small diameter end is located at the bottom. Two through holes 5 are both opened on the docking ring seat 14 and penetrate the inner cover 3. The two through holes 5 are distributed 180 degrees. A groove 9 is opened at the upper end of the outer cover 4 to match the end plate of the upper end of the inner cover 3. A silicone ring 10 is arranged in the groove 9 to match the docking ring seat 14. A plurality of anti-slip convex strips 11 are arranged on the side wall of the outer cover 4. When the outer cover 4 moves to the top, the silicone ring 10 abuts against the outer side of the docking ring seat 14. At this time, the silicone ring 10 blocks the two through holes 5 to prevent liquid from flowing out. At the same time, the anti-slip convex strips 11 facilitate the rotation of the outer cover 4. The two through holes 5 designed at 180 degrees can prevent one through hole 5 from discharging liquid while the other through hole 5 is discharging liquid. The groove 9 can wrap the upper end of the outer cover 4 around the upper end of the inner cover 3, so that the upper ends of the two are flush and more beautiful.

[0027] As an optional embodiment, the second thread structure includes a spiral pattern 8 opened on the outside of the inner cover 3 and the bottleneck 2, and the inner wall of the outer cover 4 is threadably adapted to the spiral pattern 8, and the spiral direction of the threaded ring 7 is consistent with that of the spiral pattern 8. The consistent spiral direction allows the inner cover 3 to be tightened together when the outer cover 4 is rotated and tightened, thereby avoiding the inner cover 3 from loosening after the outer cover 4 is tightened.

[0028] Specifically, two indicator arrows 12 are provided on the upper end surface of the inner cover 3, and the tips of the two indicator arrows 12 point to the two through holes 5 respectively. A plurality of anti-slip grooves 13 are provided on the side walls of the end plates of the inner cover 3. The indicator arrows 12 can enable the user to know the position and direction of the through holes 5 more intuitively and quickly. At the same time, the anti-slip grooves 13 can facilitate the rotation of the inner cover 3 to remove it.

[0029] With the above structure, when in use, water is poured into the bottle body 1, the outer cover 4 is first sleeved on the outside of the bottleneck 2 through the second threaded structure, and then the inner cover 3 is installed in the bottleneck 2 through the first threaded structure. Then, the index finger and thumb are used to pinch the two sides of the outer cover 4 and rotate it, and the other fingers and the palm cooperate to control the bottle body 1, so that the outer cover 4 can be adjusted up and down on the outside of the inner cover 3 and the bottleneck 2. When the upper end of the outer cover 4 coincides with the upper end of the inner cover 3, the two through holes 5 are blocked and liquid cannot be discharged. At the same time, when the two through holes 5 are exposed, one of the through holes 5 discharges liquid and the other through hole 5 takes in air.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
