WIPO Patent Application WO/2020/242026
Kind Code:
A1
Abstract:
According to the present invention, an adjustment part is provided on both lower sides of the outer surface of a mask, and pulling parts are formed by means of one side of each ear band passing through a corresponding adjustment part in the horizontal direction, and when the ear bands, of which the lengths have been adjusted by the pulling parts, are looped around the ears of a user, the ear bands and the pulling parts are bent by 180 degrees by means of the adjustment parts, thereby enabling the length-adjusted state of the ear bands to be stably maintained, and thus the mask firmly and tightly adheres to the facial area of the user, and consequently, by maintaining the state where the mask stably and tightly adheres to the facial area of the user, a benefit may be gained of smoothly filtering harmful substances in outside air.
