Filtering face-piece respirator with increased friction perimeter |
| abstract |
FIELD: personal and household items. n SUBSTANCE: filtering face-piece respirator 10 that includes harness 14 and mask body 12 that has multi-layer filtering structure 16. At perimeter 24 on the interior surface of mask body 12 there is region having an increased coefficient of friction 44, in relation to filtering structure 16. This region 44 can be formed by a discontinuous coating of a polymeric material. n EFFECT: region 44 improves the fit of the respirator 10 on the wearer's face, providing a non-slip seal, yet allows moisture laden air to exit from the interior gas space of mask body 12. n 19 cl, 13 dwg, 1 tbl |
