Abstract (en)
[origin: US2014182601A1] A filtering face-piece respirator 10 that includes a harness 14 and a mask body 12. First and second bond lines 30a, 30b are located on opposing sides of the mask body 12 and join a top portion 18 of the mask body 12 to the bottom portion 20. The first and second bond lines 30a, 30b extend from the frontal line of demarcation 22 to upper and lower perimeter segments 24a, 24b. The upper and lower perimeter segments 24a, 24b have an upper linear segment 32a and a lower linear segment 32b, respectively, located between first and second curved portions 34a, 34b. The first and second curved portions 34a, 34b each extend from the respective upper or lower linear segment 32a, 32b to the first and second bond lines 30a, 30b. The invention provides a more rounded finish to the mask body perimeter, which enables the mask body to exhibit a more comfortable fit.
