PROBLEM TO BE SOLVED: To improve the protective properties in relation to a disposal mask.;SOLUTION: In the mask, a square sheet 1 of a breathable material is formed a mountain fold and a valley fold along the horizontal axis, and this folding process is repeated for several times to form a gather 2 at the middle of the sheet 1. And adhesive bands 5, 5a are formed at both the ends of the gather 2 and each gathering of the gather 2 is united at the only both ends. Linear fusion concave parts 6, 6a are formed by heat pressing the adhesive bands 5, 5a to be almost parallel to the horizontal axis and a plurality of the fusion concave parts 6, 6a are formed over the upper and lower ends of the adhesive bands 5, 5a at predetermined intervals. One end and the other end of ear loops 7, 7a are mounted at the upper end and the lower end of the adhesive bands 5, 5a respectively, and so the upper and lower ends of each fusion concave parts 6, 6a become fold lines to deform the adhesive bands 5, 5a to be like fine gathers. Both ends of the mask are fitted at a cheek by the above process when the mask is worn and the adhesion is improved.;COPYRIGHT: (C)2007,JPO&INPIT
