1.Make a diameter 2 to 3mm diameter in the middle of the bottle cap .
2. The bottle can not be inverted for a long time, the inverted liquid will plug the porous pores, resulting in no permeability.

4.Barrel piercing can not burr, otherwise it will penetrate the membrane, resulting in liquid leakage.
