| Abstract: |
A face mask able to appropriately cover the nose is made of a sheet of flexible material which forms the body of the mask. The upper portion of the body is so folded that two opposing sides of the folded upper portion are folded downward and decline toward the center of the body of the mask to positions whereat each of the two sides of the folded upper portion are stitched to the mask body at an appropriate distance apart, thereby forming an inverted, concave, V-shaped flange which provides a space which accommodates the nose of the wearer, without leaving a gap between the mask and the face of the wearer at each side of the nose.
