PROBLEM TO BE SOLVED: To provide an artificial nipple for a nursing bottle capable of fitting the nipple top part closely to the sucking fossa of an infant while avoiding deformation of the nipple top part even if its shape is similar to a human nipple, and preventing the nipple top part from contacting firmly during the peristaltic movement.SOLUTION: The artificial nipple for a nursing bottle has a nipple top part having a dispensing hole of a liquid drink at the tip, and an artificial nipple body 3 which is continuous to the nipple top part, and whose diameter and wall thickness are greater than those of the nipple top part. The artificial nipple is made of a flexible material. The nipple top part has a rib 6, 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 while an upper lip A1 of the infant A is in contact with the artificial nipple body 3 or at an internal surface in the vicinity of the portion.COPYRIGHT: (C)2007,JPO&INPIT【課題】人間の乳首に類似する形状であるにも拘わらず、乳頭部がいびつにならずに乳幼児の吸啜窩に密着フィットさせることができ、また、蠕動様運動中に乳頭部が密着するのを防止することができる哺乳瓶用人工乳首を提供する。【解決手段】先端に液体飲料の流出孔を有する乳頭部と、前記乳頭部と連続し、前記乳頭部より大径且つ厚肉の胴部3とを備え、可撓性を有する材質で形成され、前記乳頭部は、乳幼児Aの上唇A1が前記胴部3に接触した状態において乳幼児の歯茎部が当たる部位又はその近傍の内周壁に、前記乳頭部が扁平して上側乳頭部と下側乳頭部とが密着するのを防止するためのリブ6を設けたことを特徴とする。【選択図】図5
