Leakage-proof PET bottle

Abstract

According to the leakage-proof PET bottle, in the working process of the leakage-proof PET bottle, when the leakage-proof PET bottle needs to be opened or closed, the extrusion outer cover is pressed downwards, so that the extrusion outer cover extrudes the compression spring, and the inner wall of the sealing end of the extrusion outer cover abuts against the containing pipe. In the process, the rotating inner cover is inserted into the arc-shaped sliding grooves and is in sliding connection with the limiting blocks. At the moment, the compression spring in the compressed state can be completely contained in the containing pipe. And each driving block is correspondingly inserted into the corresponding U-shaped clamping plate. The outer extrusion cover is rotated to drive the driving block to rotate, and the rotating inner cover is driven to rotate through the U-shaped clamping plate in the rotating process of the driving block, so that the leakage-proof PET bottle is opened or closed. And the soft sealing gasket can improve the sealing performance of the leakage-proof PET bottle. According to the leakage-proof PET bottle, the situation that the leakage-proof bottle cap is rotated due to misoperation can be avoided, so that the sealing performance of the bottle opening of the PET bottle is improved, and the leakage problem caused by misoperation is avoided.
