PROBLEM TO BE SOLVED: To improve a conventional mask which is inconvenient because spectacles become dim by breathing out and because a gauze touches the mouth, resulting in adhesion of a lipstick to it and a choking sensation. SOLUTION: A mouth openwork mask in which spectacles are not dim because it is made of a wire which may be curved and free, is in a form along the face, and is well-ordered in a nose and the wings of the nose to be well- fitting and there are no choking sensation and no feeling thirsty or the like because openwork may be made in the mouth and further which may be worn with putting on lipstick. It may be put in a pocket in a flat form when not in use (its central part is swollen when in use). |
