[0025] Reference Figures 1 to 6 A type of push-button pump with a protective cover;

[0026] Reference Figure 1-3 The device includes a threaded thread 1, a pusher 2 vertically slidably connected to the threaded thread 1, and a liquid outlet 21 on the pusher 2. It also includes an annular threaded thread 1 fitted onto the threaded thread 1, and mutually adapted guide portions 11 and guide grooves 31. One of the guide portions 1 and guide grooves 31 is located on the threaded thread 1, and the other is located on the protective cover 3. The protective cover 3 has a blocking portion 30. After the protective cover 3 rotates a certain angle around the threaded thread 1 along the trajectory of the guide groove 31, the blocking portion 30 can block the liquid outlet 21.

[0027] like Figure 1 The outlet 21 is exposed outside the shield 30. For example... Figure 2 When the protective cover 3 is rotated at a certain angle, such as 90°, the liquid outlet 21 is blocked by the blocking part 30. The protective cover 3 can be raised to block the liquid outlet 21 by using the guide part 11 and the guide groove 31, or the staggered shape of the top edge of the protective cover 3 can be used to rotate the higher part of the protective cover 3 to the position that blocks the liquid outlet 21.

[0028] Reference Figure 4-5 The guide groove 31 is spiral-shaped with a certain vertical lift.

[0029] Reference Figure 4-5The protective cover 3 has an installation notch 32, which is flared out of shape with a larger bottom and a smaller top. The top of the installation notch 32 communicates with the lower part of the guide groove 31. When the protective cover 3 is installed on the thread 1, it can be slipped onto the thread 1 from top to bottom. The guide part 11 enters the guide groove 31 through the installation notch 32. Because the installation notch 32 is flared out of shape with a larger bottom and a smaller top, the guide part 11 is difficult to pull out after entering the guide groove 31.

[0030] Reference Figure 4-6 In a further preferred embodiment, the lower end of the guide groove 31 is provided with a first stop platform 311, the upper end of the guide groove 31 is provided with a second stop platform 312, and the guide portion 11 is provided with a stop groove 111. Both the first stop platform 311 and the second stop platform 312 can engage with the stop groove 111. The advantage of this embodiment is that it temporarily fixes the relative angle between the thread 1 and the protective cover 3.

[0031] In a further preferred embodiment, when the guide portion 11 engages with the first stop platform 311, the bottom of the guide portion 11 overlaps the top of the mounting notch 32. At this time, the protective cover 3 cannot be screwed downwards relative to the thread 1.

[0032] Reference Figure 3 and Figure 5 In a further preferred embodiment, the protective cover 3 is provided with an anti-detachment platform 33, the bottom of the push head 2 is provided with an anti-detachment surface 22, the top of the anti-detachment platform 33 can abut against the anti-detachment surface 22, and the anti-detachment surface 22 is used to limit the highest position of the anti-detachment platform 33.

[0033] As an optional embodiment, the blocking part 30 is an upwardly extending arc shape. This is one way to achieve the blocking part 30 blocking the liquid outlet 21 after rotation. In this case, the guide groove 31 may not have a vertical lift.

[0034] This utility model also provides a packaging bottle, including the aforementioned press pump with a protective cap, and also includes a bottle body 4, wherein the screw thread 1 is installed at the bottle mouth of the bottle body 4.

[0035] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
