When the cartridge is turned upside down, the mechanism prevents the ink from flowing freely by creating a seal or using a viscous ink formula. This prevents the ink from running down and leaking out of the cartridge. Additionally, the cartridge is designed to maintain a certain pressure inside, which also helps to keep the ink in place. **
