First Claim
Patent Images
1. A method for fabricating a sanitary face mask, comprising;
- fabricating a layer of meltblown polypropylene fabric having a horizontal and vertical axis;
forming at least one pleat in the meltblown layer along the horizontal axis thereof such that the pleated meltblown layer is dimensioned to fit over the mouth and nostrils of a wearer;
heat sealing the sides of the pleated meltblown layer along the vertical axis thereof to allow the pleats to expand in the center portion only;
disposing a semi-rigid member along one edge of the pleated meltblown layer parallel to the horizontal axis thereof and folding a portion of the edge over the semi-rigid member, the folded-over portion being heat sealed about the perimeter of the semi-rigid member to completely enclose the semi-rigid member;
forming first and second ear loops from narrow strips of a combination of textured polyester and lycra spandex, said combination comprising 90.33 percent textured polyester and 9.67 percent lycra spandex so that the edges of each of said ear loops curl over to form a rounded cross section therefor; and
attaching the free ends of each of the ear loops on opposite ends of one of the lateral sides of the pleated beltblown material on a vertical edge thereof by heat bonding.
