发明名称 MASK WITH NOSAL CUSHION
摘要 Provided is a mask with a nosal cushion, the mask consisting of a filter that filters dust, wherein, the edges of the filter are folded back to create flaps that follow the depressions on both sides of the nosal region. A sponge of urethane foam or the like is affixed inside the flaps, thereby improving the fit of the mask by conforming the mask to the contours of the nosal region, resulting in a mask cushion with a nosal cushion that has cushioning properties and strong protective capabilities.
