Face mask
An off-the-face mask including a mask body comprising one or more layers and having a surface area defined by a plurality of zones, wherein at least two of the plurality of zones have different stiffness levels; and one or more straps coupled to the mask body and configured to hold the mask on a wearer of the mask.
1. An off-the-face mask comprising:
a mask body comprising one or more layers and having a surface area defined by a plurality of zones, wherein at least two of the plurality of zones have different stiffness levels; and
one or more straps coupled to the mask body and configured to hold the mask on a wearer of the mask;
wherein:
the different stiffness levels each correspond to a different thickness of the mask body,
the plurality of zones comprise a nose contacting portion proximate a nose of a wearer when the mask is worn; a chin contacting portion, opposite the nose contacting portion, proximate a chin of the wearer when the mask is worn; upper and lower left side portions collectively extending proximate a periphery of the mask body between the chin and nose contacting portions on one side of the mask body; upper and lower right side portions, opposite the left side portions, collectively extending proximate the periphery of the mask body between the chin and nose contacting portions on an other side of the mask body; and a first central portion surrounding an apex portion in a middle of the mask body; and a second central portion surrounding the first central portion and between the chin contacting, nose contacting, left side and right side portions; and at least two of the first central, second central, apex, chin contacting, nose contacting, upper and lower left side and right side portions have different stiffness levels,
the nose contacting portion has a lowest stiffness level and at least one of the chin contacting portion and first central portion have a highest stiffness level, and wherein the upper and lower left side and right side portions have stiffness levels greater than the nose contacting portion and the first central portion has a stiffness level greater than the second central portion.
2. The mask of claim 1 , wherein the first central and chin contacting portions have the same stiffness level.
3. The mask of claim 1 , wherein the different stiffness levels have a lowest stiffness level and a highest stiffness level and the highest stiffness level is at least two times that of the lowest stiffness level.
4. The mask of claim 1 , wherein one of the plurality of zones having the highest stiffness level has a thickness of between 0.3 to 2 mm.
5. The mask of claim 4 , wherein one of the plurality of zones having the lowest stiffness level has a thickness of between 1.5 to 4 mm.
