PROBLEM TO BE SOLVED: To provide an artificial nipple for eliminating the generation of a segment and preventing a suckling opening from being split for a long term, and also to provide a formation blade therefor.SOLUTION: Suckling slits are formed in a tip part of an artificial nipple. Cuts are formed outside from respective ends of the slits to intersect with the extension lines of the slits along the tip part. It is preferable that the cuts are in a fine linear shape to vertically intersect with the extension lines of the suckling slits. The cuts are formed at least by press-cutting work to thereby eliminate the generation of a segment.COPYRIGHT: (C)2014,JPO&INPIT【課題】切片が発生せず、吸飲口の開裂をより長期に防止した人工乳首と、その形成刃を提供する。【解決手段】乳頭部に吸飲用のスリットを形成した人工乳首において、前記スリットの端部それぞれから外側に前記スリットの前記乳頭部に沿った延長線と交差して切り込みを形成した。切り込みは吸飲用スリットの延長線と垂直に交差する微細な線状であることが好ましい。また、少なくとも切り込みは押し切り加工によって形成することで切片が出ない。【選択図】図1
