ABSTRACT:
A noncollapsing pleated face mask (10) is disclosed. The face mask (10) is constructed entirely of heat seal bondable fabric. The mask (10) includes a trapezoidal-shaped single pleat (16) having reinforced side edges (30,32), and a reinforced folded longitudinal edge (28). The reinforcement along the diagonal side edges (30,32) and the longitudinal folded edge (28) is continuous so as to provide a pleated structure which resists deforming and collapsing against the wearer's face.
