ABSTRACT:
An air intake aiding plate structure for nipples of feeding bottles, in particular an aiding plate that is adapted to be disposed below a nipple to hold the nipple in position together with a nipple locking cap. The aiding plate has an annular depression located below an air slit of the nipple for receiving air induced via the slit. The annular depression has an air intake hole that extends downwardly to connect to an integrally formed extended air intake tube to guide the air deep into the feeding bottle so as to balance the air pressure inside the bottle. Hence, the air guided into the feeding bottle will avoid the mouth of the nipple where the fluid suction force is strong, and the passages of air and fluid will be separated, thus preventing entry of air into the baby's stomach during feeding.
