The utility model is easy to use and has high reliability and practicality.
[0004] The utility model comprises a combined plastic bottle cap, comprising a main body and a sealing sheet, wherein a cavity is arranged inside the main body, the upper end of the main body is an opening, the lower end of the main body is provided with a sealing port communicating with the cavity, and the sealing sheet is installed at the sealing port at the lower end of the main body; the utility model also comprises an ejection core, a sealing cover and a linkage mechanism, wherein a cavity is arranged inside the ejection core, the upper and lower parts of the ejection core are both openings, the middle part of the ejection core is slidably installed in the cavity of the main body, the upper part of the ejection core is connected with the sealing cover through a linkage mechanism, the upper end of the main body is provided with a sealing cover, and the linkage mechanism has a linkage function; the main body is fixedly installed on the plastic bottle, and the The lower part is located at the bottle mouth of the plastic bottle. When the sealing cover is opened, the sealing cover pushes the ejection core to move downward through the linkage mechanism. The ejection core pushes open the sealing sheet at the lower end of the main body while moving downward, so that the sealing opening at the lower end of the main body is unobstructed. After that, people can let the liquid in the plastic bottle flow out of the blade outside through the ejection core and the main body and then use it. When the bottle cap is opened, the sealing sheet on the bottle cap can be automatically pushed open, and people do not need to use other tools to poke the sealing sheet, which is convenient to use and avoids contamination of the liquid in the plastic bottle when using other tools to poke the sealing sheet. The reliability and practicality are high.

The linkage mechanism has a linkage function. The main body 1 is fixedly installed on the plastic bottle. The lower part of the main body 1 is located at the bottle mouth of the plastic bottle. When the sealing cover is opened, the sealing cover pushes the ejection core 3 to move downward through the linkage mechanism. The ejection core 3 pushes open the sealing sheet 2 at the lower end of the main body 1 while moving downward, so that the sealing opening at the lower end of the main body 1 is unobstructed. After that, people can let the liquid in the plastic bottle flow out of the blade outside through the ejection core 3 and the main body 1 and then use it; when the bottle cap is opened, the sealing sheet on the bottle cap can be automatically pushed open, and people do not need to use other tools to poke the sealing sheet, which is convenient to use and avoids the contamination of the liquid in the plastic bottle when using other tools to poke the sealing sheet, and has high reliability and practicality.
