Artificial nipple for a nursing bottle

摘要

An artificial nipple for a nursing bottle having a nipple top part having at its tip a dispensing hole for dispensing a liquid drink; and an artificial nipple body which is continuous to the nipple top part, and whose diameter and wall thickness are greater than those of the nipple top part. The nipple top part has a rib, which prevents contact between an upper side and a lower side of the nipple top part when the nipple top part is compressed flat, at a portion where gums of an infant touch when an upper lip of the infant is in contact with the artificial nipple body or at an internal surface in the vicinity of the portion.
