The invention belongs to the technical field of components of infant
nursing bottles, and particularly relates to an entity nipple with an adapter. The entity nipple comprises a nipple head part, a base part and a bottom part, a liquid outlet hole or a liquid outlet gap is formed in the nipple head part, and an air
inlet valve is arranged by the nipple base part and the bottom part jointly; a clamping groove matched with a
nursing bottle lid is formed in the junction of the nipple base part and the bottom part, the nipple is of an entity structure, a center tubular channel is arranged along the axis of the nipple head part, the base part and the bottom part and is longitudinally
cut through, the hollow adapter is connected to the lower portion of the center tubular channel and is longitudinally
cut through, the end surface of the bottom part is a flat plane or an inward
concave surface, and the end surface of the lower portion of the center tubular channel does not protrude out of the flat plane or the inward
concave surface of the end surface of the nipple bottom part. The entity nipple with the adapter can prevent
flatulence, and milk can be sucked through one breath; it can also be guaranteed that a
newborn infant can suck milk thoroughly in the nipple on the premise that the adapter and a
straw are not utilized, and the waste of the milk is thus avoided; meanwhile, the nipple can be made to be very soft, collapse and deformation are avoided, the universality is good, and the application range is wide.
