When using a new cup for the first time, it is necessary to remove the cup lid and silicone seal ring, thoroughly clean it with warm water and neutral detergent, rinse it clean and dry it before use; Preheat the inner container with warm water to reduce the damage caused by sudden cooling and heating, and extend the service life of the cup.
Do not fill the cup with hot water and leave a small amount of air space to avoid scalding caused by hot water overflowing when tightening the cup lid; After adding boiling water, do not immediately close the cup lid and shake it, otherwise the air inside the cup will expand due to heat and the pressure will suddenly rise, which can easily cause boiling water to splash and pose a risk of burns.
Daily storage requires keeping the cup dry, promptly pouring out any remaining water after each use, opening it for ventilation and drying to avoid the growth of mold and odor in a sealed and humid environment. Keep away from open flames and high temperature heat sources when placing to prevent deformation of the cup body, peeling of paint, and damage to the vacuum layer.
