Transparent screw bottle with good sealing performance

The invention belongs to the technical field of transparent containers, particularly relates to a transparent screw bottle with good sealing performance, and aims to solve the problems that an existing screw bottle can only play a certain isolation role at a bottle opening and is single in limiting function, and external bacteria can enter the periphery of a silica gel gasket along a thread gap in the outer wall of the screw bottle opening. According to the following scheme, the transparent screw bottle comprises a screw bottle body; a bottle opening is formed in the screw bottle body, outer ring threads are arranged on the outer wall of the bottle opening, open grooves are formed in the two sides of the outer ring threads, communicating hoses are arranged on the inner walls of the two open grooves, a first mounting groove is formed in the outer wall, close to the top, of the bottle opening, and a second mounting groove is formed in the outer wall, close to the bottom, of the bottle opening; and a top ring ai
