ABSTRACT:
The device offers an improved structure of bottom inlet nursing bottle, wherein an opening at the bottle bottom is provided with a unilateral diaphragm which can open only inward but close outward so as to help the baby suck milk comfortably together with the air introduced into the bottle from the bottle bottom. A protective plate is provided on the outer bottom surface and is able to open or close. An air inlet regulating device is provided on the protective plate and able to regulate the size of the air inlet so as to meet the different inlet volume of different babies. The air inlet can be closed so as to prevent the milk in the bottle from seeping out when preparing the milk and to prevent the warm-keeping water and the impurity in the water from infiltrating into the bottle when warming the milk.
