AI Technical Summary
The straws in existing cups are prone to deformation or breakage after long-term use, and they are not easy to quickly reset when drinking water, which affects the service life and drinking convenience.
Design a cup lid, including a lid body, a tube body, a stopper, and a unlocking component. The tube body slides into the lid body and is equipped with an elastic component. The tube body pops out when drinking water by operating the unlocking component. The stopper seals the tube body in the closed state and automatically separates when unlocked. Combined with a vent hole and a vent groove, it balances the air pressure and ensures smooth drinking.
It increases the lifespan of straws, prevents straw damage, ensures smooth and safe drinking, and reduces costs and operational difficulty.
