Liquid Quantitative Cap / Liquid Quantitative Cap

Liquid medicine requires accurate measurement. But how exactly do you pour out the need to take a mount? If the liquid poured too much, put back into the bottle is not only difficult to operate, but also pollution of medicine. This design is a cap, which will not contact with the outside air, and help us to measure liquid medicine exactly. By turning left or right, the cap will transfer the liquid medicine, just like a transfer station. The whole process does not need to contact the outside the bottle, health and safety.
