PROBLEM TO BE SOLVED: To provide a nose piece capable of reducing a burden applied to the nostrils, nebulizer device, and molding die.SOLUTION: When an external shape of a tip end of a nose piece is so formed that an average figure of infants, an average figure of children, an average figure of men (adult), and an average figure of women (adult) are overlapped in the lateral direction and the depth direction, a specific area that does not come into contact with any figure is defined. The external shape of the tip end is so changed that, for example, a side facing the tip end is flattened, out of the specific area in the tip end part. In other words, in the tip end, a curvature radius r1 of a part facing the nasal septum of the nostril is larger (r1>r2) than a curvature radius r2 of the other parts. Namely, in the nose piece, the part facing the nasal septum of the nostril in the tip end has the curvature radius larger than that of the other parts.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2019,JPO&INPIT【課題】鼻孔への負担軽減を図ることが可能なノーズピース、ネブライザ装置および成形用金型を提供する。【解決手段】ノーズピースの先端部の外形形状を、幼児平均の図形、小児平均の図形、男性(大人)平均の図形および女性(平均)の図形を横方向および奥行き方向で重なるようにした場合に、いずれの図形にも接触しない特定領域を画定した。先端部の外形形状は、例えば先端部における特定領域のうち、先端部に対向する側がより平たんになるように変更されている。言い換えると、先端部において鼻孔の鼻中隔に臨む部分の曲率半径r1は、他の部分の曲率半径r2よりも大きい(r1>r2)。すなわち、ノーズピースでは、先端部において鼻孔の鼻中隔に対峙する部分は、他の部分よりも曲率半径が大きい。【選択図】図4
