Document Type and Number:
Japanese Patent JP2018175136
Kind Code:
A
Abstract:
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 4
