摘要
A cup-shaped filtering face-piece respirator 10 that includes a harness 14 and a mask body 12 that has a multi-layer filtering structure 16. The mask body 12 includes at least one dart 60 permanently bonded in the filtering structure 16, the dart 60 tapering from a center plane 32 of the mask body 12 to a side edge of the mask body. The dart 60 inhibits collapse of the cup-shaped form of the respirator 10. 展开▼
