US 2021/0329987 A1 · FACE MASK

Abstract

A face mask is made from five layers of surgical drape, synthetic filtration material having a bacterial filtration effective of 95% and a synthetic MERV-13 filtration material. The five layers are folded and cut on each side at approximately 45 degrees. Front folds provide a pocket for air exchange in the front area of the face mask. Edge folds provide a border and hold a memory strip in place over wearer's nose. The 45 degree sides are sewed together with a border, plus attaching ends of two bungee strips thereto. The first bungee strip extends to the neck area below the head of the wearer and, with a first bungee lock, pulls the face mask into the nose. The second bungee cord strip extends to the top rear of head of the wearer and, with a second bungee lock, pulls the mask under the chin. By pressing the memory strip and tightening the bungee locks, a tight fit is provided on the face mask to the wearer.

placing five layers of approximately 12″ by 12″ filter material on top of each other;
first folding said five layers along a center line to form a rectangle with two approximately 1″ expansion folds adjacent said center line;
second folding outer edges of said five layers to create an upper outer fold and a lower outer fold;
cutting off corners along said center line of said rectangle at approximately 45 degrees, to give an angled cut;
first sewing a flexible memory strip in a center of said upper outer fold to form an upper seam;
second sewing said lower outer fold to form a lower seam;
third sewing said angled cuts to maintain said five layers with said expansion folds;
first attaching during said third sewing step, a shorter of the two elastic strips on either end thereof to opposing sides of said angled cuts to pull said face mask into a nose area of said wearer;
and
