AI Technical Summary
Technical Problem
Existing glass bottles struggle to balance sealing and ease of opening; users with weak hand strength may have difficulty opening the caps, and there is a risk of liquid leakage.
Method used
A threaded section is provided at the top of the bottle body, and a limiting strip and a sealing ring are installed inside the bottle cap. The sliding column is raised and lowered by a knob, and the pressure relief hole releases air, reducing the opening force. Liquid leakage is prevented by the limiting frame and the limiting strip.
Benefits of technology
It improves the sealing of glass bottles, reduces the force required to open the cap, prevents liquid leakage, and is suitable for users with weak hand strength.

Abstract
The utility model discloses a glass bottle with strong leakproofness, which comprises a bottle cap, the side surface of the bottle cap is provided with anti-slip lines, the inner side wall of the bottle cap is fixedly connected with a limiting strip, the top surface of the bottle cap is fixedly connected with a sealing ring, the upper surface of the bottle cap is rotatably connected with a knob, the inside of the bottle cap is slidably connected with a sliding column, and the sliding column is fixedly connected with the bottle cap. A thread II is formed in the side surface of the sliding column; a first thread is arranged at the top end of the bottle body, a limiting frame is arranged above the first thread, and a leakage-proof ring is fixedly connected to the top end of the bottle body. By means of the structure, the sliding column can be driven to ascend and descend through the second thread by rotating the rotary knob, gas in a bottle can be exhausted through the pressure relief hole in the sliding column, the force needed for unscrewing the bottle cap is reduced, and a user with the weak hand force can use the bottle cap more conveniently.
