Energy-saving Barrel Can / Energy-saving Barrel Can

Gdnerally,it is not easy to make full use of paint on barrel in use because it always remains some paint in the barrel top.So,it will waste a lot of paint in use on this situation .
The biggest highlight of this design aims at improving bucket's structure by designing a reflux device on the cover The reflux device not only can be used as a drainage port through ripping along the dotted line when needed ,but also it can be put into the barrel again in no use, and then close the lid to preserve the paint.
