The system provides cushioning and shock absorption, extending the service life of the inner liner 2 and the telescopic sleeve 3. The telescopic sleeve 3 is threadedly connected to the cup lid 4. By rotating and tightening the threaded connection, a uniform axial pressure is generated between the telescopic sleeve 3 and the cup lid 4, forcing the sealing ring 403 to deform under pressure and fill the microscopic gaps.
