Abstract: An improved structure of feeding bottle is composed of a bottle main body, a hard ferrule, a silicon gel ventilative gasket, and a bottom closure. A thoroughly opened bottom opening formed at bottom end of the bottle main body is covered with the hard ferrule and the ventilative gasket one after the other, then sealed by swiveling the bottom closure. A through hole and a vent are formed in the hard ferrule and in the bottom closure respectively. One or at least one protrusion is disposed on the ventilative gasket within confines of the through hole in the hard ferrule, wherein a slot or cross cut is formed in top face of the protrusion. By means of packing effect of the hard ferrule, the ventilative gasket can attach to the bottom closure without detaching from the bottom opening for providing an easy-cleaning, leakage-proof, and convenient feeding bottle.
