US Patent 8061356 Directional flat face mask

A face mask has mask material and ties or ear loops coupled to the mask material. The face mask is flat until worn. The mask material has an outside and an inside, which inside is designed to be against the wearer's face when the mask is worn. A deformable nose strip is provided near a top edge of the mask material. The nose strip is preformed into a contour for fitting about a nose. The contour bows out from the inside to the outside. A wearer donning the mask intuitively knows to orient the contour to the wearer's nose, wherein the inside is automatically positioned against the wearer's face.
