| Abstract: |
A face mask cut from a sheet of foamed resin material has slits cut near each end shaped to curve inwardly in a U shape. The ends of the mask conform approximately to the U shape of the slits so that the material between the slits and the ends of the mask forms a pair of U-shaped ear loops. The ear loops are bendable in a one-half turn so that the U shapes extend outwardly away from the central portion of the mask for resiliently looping over the ears of the wearer to hold the mask in place.

What is claimed is:
1. A face mask shaped to cover the nose and mouth of the wearer, said face mask comprising:
- a. a blank of resilient, foamed resin material having a central region and opposite end regions, each opposite end region of said mask having a slit spaced inward from the end of said mask;
- b. each of said slits extending from upper to lower regions of said mask;
- c. a central portion of each of said slits being U-shaped and curving inward toward said central region of said mask;
- d. said end regions of said mask having a peripheral edge spaced approximately equidistant from said slits so said material between said slits and said ends of said mask has an approximately uniform width and forms a pair of ear loops having U-shaped portions; and
- e. said ear loops being bendable in a one-half turn to dispose said U-shaped portions to extend outwardly away from said central region for resiliently looping over the ears of the wearer to hold said mask in place.
