PROBLEM TO BE SOLVED: To provide an artificial nipple structure that facilitates absorption even if an air-hole is not provided, and furthermore, and has no leakage from a mouthpiece at all even if an artificial nipple is directed downward.SOLUTION: An artificial nipple attached to the mouth part of a container is constituted. A connection part 10 detachably connected to the container mouth is provided. A dome-shaped suction port 20 extended from the connection part 10 is provided. A thick part 21 of a side surface fan shape is formed along the tip portion of the suction port 20. A cut is put along a longitudinal direction of the thick part 21 to form a suction hole 22. A plane circular thin-walled part 23 is formed around the thick part 21.SELECTED DRAWING: Figure 1【課題】空気孔を設けなくても吸引が容易で、しかも人工乳首を下向きにしても吸い口から全く漏れずにすむ人工乳首構造を提供する。【解決手段】容器の口部に装着する人口乳首を構成する。容器口部に着脱自在に連結する連結部１０を設ける。該連結部１０から延長されたドーム形状の吸口部２０を設ける。吸口部２０の先端部分に沿って側面扇形状の肉厚部２１を形成する。該肉厚部２１の長手方向に沿って切目を入れて吸孔２２を形成する。該肉厚部２１の周囲に平面円形状の肉薄部２３を形成する。【選択図】 図１
