A kind of improvement construction of feeding bottle,It ties up between feeding bottle opening and nipple and bottle cap and is equipped with a control sheet annular in shape,Wherein,The ring circle periphery that control sheet ties up to dented space is equipped with flange face,Make the blocking surface of dented space bottom surface closed,An airflow hole is equipped in blocking surface,And blocking surface and be equipped with a micro- high what flange face fin ring,Bottom surface middle position in fin ring is equipped with an aperture； And the nipple for sucking by suck end,It sucks body and opening periphery is constituted,And make to suck end,It sucks body and forms connected open space,Front position end suck end system relatively suck body with a thickness of thickness except,And two tap holes with gradually outside contraction-like taper aperture are equipped with,And two tap hole system be in eight shape； Then what feeding bottle opening periphery Hou is set with the flange face paste for control sheet,The opening periphery of nipple is attached on the flange face of control sheet again,Think that the fin ring of control sheet gets enter into the open space of nipple,Hou again by eat dishes without rice or wine in bottle cap upper shield feeding bottle Hou,Be screwed by the external screw thread of its internal screw thread and feeding bottle open circumferential,And it gives abutting and is pressing against nipple and control sheet； So exported with the liquid being able in control feeding bottle for control sheet to the flow of nipple,It is inhaled slowly for infant is suitable againIt suckes, and by position front position end suck end system relatively suck body with a thickness of thick one, it can avoid causing tap hole to become larger due to stinging because inhaling for a long time, larynx situation of choking is caused to avoid because nipple discharge is excessive, the opening periphery close to nipple is also fastened by the flange face of
