1. A face mask comprising:
- a generally cup shaped mask body having an opening and a recess, the recess shaped to receive oral and nasal features of a human face, the opening having a peripheral edge being shaped to generally follow a contour of a human face extending around the nasal and oral areas;
a plastically deformable shape-retention member disposed in the vicinity of a portion of the peripheral edge, the shape-retention member being sized to extend across a bridge of a human nose;
at least one retention member attached to the mask body, the retention member being configured to extend around a rear side of a human head so as to retain the mask body against a face of a human; and
a vapor diversion member disposed adjacent to the shape retention member, the vapor diversion member comprising a thermally-sensitive visco-elastic material having at least a first area having a first thickness positioned to be alignable with a bridge of a human nose, and at least second and third areas disposed adjacent to the first area and having second and third thicknesses, both of which are thicker than the first thickness.

Abstract
A face mask, or other wearable article, can include a visco-elastic material for various purposes. For example, a face mask can include a visco-elastic member positioned to be alignable with the bridge of a user'"'"'s nose and shaped so as to extend over the junction between the user'"'"'s nose and the user'"'"'s cheeks.

16. A face mask comprising:
-
a generally cup-shaped filter assembly having an opening and a recess, the recess shaped to receive oral and nasal features of a human face, the opening having a peripheral edge being shaped to generally follow a contour of a human face extending around the nasal and oral areas; and
a vapor diversion member disposed in the vicinity of the peripheral edge, the vapor diversion member sized to extend across a bridge of a nose of a human when the filter member is disposed over the nasal and oral areas of the face of a human; and
means for allowing a thickness of the vapor diversion member to be differentially compressed against a bridge of a nose of a human and concave areas disposed adjacent a nose of a human.
