Watertight cover / Advantageous bowl cover

Watertight cover

Watertight cover
Tradition,As the common bowl cover is designed in plane surface inside, it is very inconvenient and annoying that the water drops on the bowl cover which are formed by the condensation of water vapor would be sprinkled everywhere when we uncover the bowl cover.
Now, If we design the bowl cover in cambered surface inside, the drops will reflow into the cup along the cambered surface.
