Abstract
A face mask for wearing over mouth and nose of a user that includes a flexible body portion and one or more fasteners attached to the body portion. The body portion substantially covers a respiratory tract opening e.g. mouth and nostrils, of the user to block an entry of undesired airborne impurities into the respiratory tract opening. When the mask is worn, a front surface of the body portion is exposed to an external atmosphere and a rear surface of the body portion comes in substantial contact with the face. The fastener holds the body portion against the face when the mask is worn.

A face mask comprising:
- i. a flexible body portion for covering a respiratory tract opening of a user when in use, wherein said body portion is completely fastened along a top edge, a bottom edge and two longitudinal side edges of the body portion;
- and
- ii. at least one fastening means attached to said body portion for holding said body portion against a face of the user when said face mask is in use,
- wherein said body portion includes:
- two pleated regions, in which, a first pleated region is connected to the top edge;
- a second pleated region is connected to the bottom edge;
- a non-pleated region between the first pleated region and the second pleated region,
- wherein each of the first pleated region and the second pleated region is a three-layer thick region formed by folding portions of the body portion upon itself and back again into a Z-shape that is fastened at each longitudinal edge, and the non-pleated region is a one-layer-thick flexible and deformable region configured such that a rear portion of the first pleated region is connected to a top portion of the non-pleated region and a front portion of the second pleated region is connected to a bottom portion of the non-pleated region;
- and
- wherein, when the face mask is in use, the first pleated region, at the longitudinal side edges, overlaps at least a portion of front portion of the non-pleated region, such that a portion of the front portion of the non-pleated region that is overlapped is hidden and not visible behind the first pleated region that overlaps the at least portion of the front portion of the non-pleated region, causing each of the longitudinal side edge to transition from a straight line into a V-shape with its vertex pointed to the center of the mask body, such that rear surfaces of each longitudinal side edges contact with a cheek of the user in a tight abutment from the top edge to the bottom edge.
