Oral cavity itself is “bacterial” environment, drinking water, cover the bottle cap …… repeatedly many times a day will let the bacteria attached to the cup mouth more and more accumulated in the cap gap, very easy to enter with the water. Children commonly used press type insulation cup, the hidden danger may be greater.
