[0030] To enable those skilled in the art to better understand this utility model, it will now be further described in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this utility model.

[0031] Example 1:

[0032] like Figures 1-2 As shown, this utility model provides a press-type bottle cap assembly, which includes a detachably connected ring seat 1 and a cap body 2. The ring seat 1 is fixedly sleeved on the outer periphery of the bottle mouth. Specifically, the outer wall of the bottle mouth is provided with a ring stop fixedly connected thereto. The ring seat 1 is provided with a ring groove 13 adapted to the ring stop. The ring stop is fixedly embedded in the ring groove 13 to realize the fixed connection between the ring seat 1 and the bottle body.

[0033] refer to Figure 3 As shown, the cap body 2 is detachably mounted above the ring seat 1. The ring seat 1 is provided with at least one upwardly extending and axially (vertically longitudinally) fastening strip 11. Specifically, the ring seat 1 is provided with several fastening strips 11, which are evenly spaced along the circumference. In this embodiment, there are six fastening strips 11. A fastening ring 21 is fixedly connected to the bottom of the cap body 2 and extends downward. The fastening ring 21 and the fastening strip 11 engage to achieve a stable connection between the cap body 2 and the ring seat 1 under normal conditions, so that even if a sufficiently large pulling force is applied to the cap body 2, it cannot be separated from the ring seat 1 and the bottle body. It should be noted that under normal use, pushing the cap body 2 downward will lock the fastening ring 21 and the fastening strip 11. Pulling the cap body 2 upward will not unlock the engagement of the fastening ring 21 and the fastening strip 11. Since the fastening structure is a mature existing technology in this field, its specific structure will not be described in detail here, but can be referred to the attached drawings. Figure 3 and Figure 4 As shown in the content.

[0034] Combination Figure 3 and Figure 4 As shown, the cover body 2 has a pressing core 3 that can move up and down along the axial direction inside. Figure 3 The diagram shows the pressing column 3 in the state where it is not pressed down. Figure 4The diagram shows the pressing core 3 pressed down a certain distance. The pressing core 3 is fixedly connected to and coaxially arranged with a release ring 31. The release ring 31 is located between the latching ring 21 and the latching strip 11. Pushing the pressing core 3 downwards causes the release ring 31 to move downwards. During this downward movement, the release ring 31 gradually squeezes the latching strip 11 inwards. Under the pressure of the release ring 31, the latching strip 11 bends inwards, thus disengaging from the latching ring 21 and releasing the latching lock between the latching strip 11 and the latching ring 21. At this point, the cover body 2 can be detached from the ring seat 1. In practical use, the thumb can be used to press down on the pressing core 3 located at the center position, while the index and middle fingers grip the outer wall of the cover body 2 for fixation. When the pressing core 3 is pushed downwards until the latching engagement is released, the cover body 2 can be lifted upwards to detach it.

[0035] Furthermore, such as Figure 2 and Figure 3 As shown, the inner cylinder 4 is arranged coaxially inside the cover body 2. The inner cylinder 4 is open at the top and bottom and its top is fixedly connected to the cover body 2. The pressing column core 3 is movably arranged in the inner cylinder 4. The inner cylinder 4 is provided with a longitudinally arranged limiting groove 41 that penetrates its side wall. A support arm 32 is provided between the pressing column core 3 and the release ring 31, and both ends are fixedly connected to the two respectively. The support arm 32 is movably embedded in the limiting groove 41.

[0036] Furthermore, the limiting groove 41 and the support arm 32 are provided in several quantities and are evenly distributed along the circumferential direction. Specifically, in this embodiment, the limiting groove 41 and the support arm 32 are provided in six quantities and are evenly distributed along the circumferential direction with the axis of the inner cylinder 4 as the center.

[0037] Combination Figure 3 and Figure 4 As shown, a return spring 5 is also provided inside the cover body 2, located on the outer periphery of the inner cylinder 4. The top end of the return spring 5 abuts against the support arm 32, and the bottom end abuts against the bottom of the inner cylinder 4, so as to realize the automatic reset of the pressing core 3 and the release ring 31. Specifically, during the process of pushing the pressing core 3 downward, the return spring 5 is compressed under the downward pressure of the support arm 32. When the downward pressure applied to the top of the pressing core 3 is removed, the return spring 5 automatically extends and drives the pressing core 3 and the release ring 31 to move upward and return to their original positions, so that the locking ring 21 and the locking strip 11 can automatically lock together again during the re-fastening process of the cover body 2.

[0038] refer to Figure 3 as well as Figure 7As shown, a sealing plunger 33 is fixedly connected to the bottom of the pressing core 3 and adapted to the inner wall of the bottle mouth. The sealing plunger 33 is inserted into the bottle mouth to seal the bottle. It should be noted that even when the pressing core 3 is not pressed, the sealing plunger 33 remains inserted into the bottle mouth to ensure a good seal and prevent leakage. In addition, a sealing ring edge 42 is provided at the bottom of the inner cylinder 4, extending downward and adapted to the outer wall of the bottle mouth. The sealing ring edge 42 is located outside the sealing plunger 33 to cooperate with the sealing plunger 33 to seal the bottle mouth.

[0039] Further reference Figure 3 As shown, the bottom of the inner cylinder 4 is also provided with a downwardly extending first sealing ring 43, which is located inside the sealing ring edge 42. The top of the sealing plunger 33 is provided with an upwardly extending second sealing ring 34. There are two first sealing rings 43, which are arranged concentrically. The second sealing ring 34 is movably inserted between the two first sealing rings 43. When the pressing core 3 is not pressed, the second sealing ring 34 is embedded between the two first sealing rings 43.

[0040] Optionally, in some embodiments, the top outer edge of the ring seat 1 is provided with an upwardly extending sealing flange 12, and the bottom outer edge of the cover body 2 is provided with a sealing groove 22 located outside the buckle ring 21, and the sealing flange 12 can be movably inserted into the sealing groove 22.
