IPC: A62B18/02
Filed: 2020-10-26
Abstract: To solve the problems that physical strength is exhausted by discomfort due to stuffiness inside a mask caused by breathing when the mask is worn for a long time, and there is a risk of sucking droplets/dust from the nose when the mask is worn in a state of being shifted below the nostril in order to avoid the discomfort.SOLUTION: A stuffiness preventing mask has such a structure that a place facing the nostril of the mask is cleaved, or a mask cloth 1 covering the nose and a mask cloth 2 covering the mouth are connected, and thereby an inhaled/exhaled air from the nostril passes along the outside of the mask cloth 2 covering the mouth. The mask comprises a wire 3 for arranging the shape of the mask, the wire being located immediately under the nostril and being attached to an upper portion of the mask cloth 2 covering the mouth. By making the mask cloth located immediately under the nostril adhere to the skin by the wire 3, the inhaled/exhaled air from the nose results in passing along the outside of the mask cloth covering the mouth, and allowing stuffiness inside the mask caused by breathing to be prevented. Further, by covering the nose with the mask cloth 1, it is also possible to prevent external droplets/dust from being sucked from the nose.SELECTED DRAWING: Figure 1
