AI Technical Summary
Technical Problem
Existing squeeze-type cosmetic bottles are prone to oxidation, deterioration, and leakage due to the entry of impurities from external air pollution, and their structure and function are limited.
Method used
A straw, connecting tube, and piston are installed inside the bottle. The first and second sealing parts act as a one-way valve, drawing in liquid when a negative pressure is created, preventing external air from entering.
Benefits of technology
It effectively prevents external air from entering the bottle, avoiding oxidation, deterioration, and leakage of the cosmetic liquid, and improving ease of use and stability.

Abstract
The application discloses an extrusion type cosmetic bottle, which comprises a bottle body, a pipe body assembly and a sealing assembly. The pipe body assembly comprises a liquid outlet pipe, a suction pipe, a connecting pipe and a piston which are arranged in the bottle body. The connecting pipe has a cavity which is connected with the suction pipe and the piston. The piston is arranged in the cavity in an extendable and retractable manner. Another part of the piston extends out of the cavity and is connected with one end of the liquid outlet pipe. The other end of the liquid outlet pipe extends out of the bottle body. The sealing assembly comprises a first sealing member and a second sealing member. The first sealing member is arranged in the cavity, and the second sealing member is arranged in the piston. When a negative pressure state is formed in the cavity, the first sealing member is sucked upward to connect the suction pipe with the cavity, so that liquid flows into the cavity. The second sealing member is sucked downward to isolate the liquid outlet pipe from the cavity, so that external air is prevented from being sucked into the cavity, and oxidation and leakage of the cosmetic liquid are avoided.
