PROBLEM TO BE SOLVED: To provide a mask for surgical suits preventing the displacement of a fixing position of a mask body, reducing a burden of a wearer and reducing an infection risk by covering a nose section with the mask body corresponding to its shape.SOLUTION: An arcuate recessed section is notchedly formed into an arcuate shape at the center of an upper end edge of the mask body 4 and the upper end edge of the mask body is trimmed along the shape of the arcuate recessed section. The upper end edge of the mask body is turned down to the side of the wearer 6 to curvedly project the lower side of the arcuate recessed section to the outward, so that a nose cover section 7 capable of covering the wearers nose section corresponding to its protrusion is formed in the wearers side of the curved projecting section.COPYRIGHT: (C)2010,JPO&INPIT【課題】マスク本体により鼻部をその形状に対応して被覆することにより、マスク本体の固定位置のズレを防止し、着用者の負担が少なく、感染リスクの少ない手術着用マスクを得る。【解決手段】マスク本体4の上端縁の中央に弧状凹部を弧状に切り欠き形成し、弧状凹部の形状に沿ってマスク本体の上端縁をトリミングする。マスク本体の上端縁を着用者6側に折り返して弧状凹部の下側を外側に湾曲突出させることにより、この湾曲突出部分の着用者側に、着用者の鼻部をその突出に対応して被覆可能な鼻被覆部7を形成する。【選択図】図1
