<p>In this invention, air-blocking material is contained that enables the formation of a concentrated passage in the inner surface of the mask body that covers the nose and mouth of the user where air is concentrated and passed through at the time of inhalation and exhalation. Accordingly, concentrated passage maintains humidity and preserves heat due to the humidity and warm air of the respiration heat, produced at the time of exhalation. Consequently, cold and dry air of the outside that is the main cause of cold outbreak is converted into warm and humid air while passing through the concentrated passage, which in turn prevents worsening of cold symptoms and the outbreak of cold. <??>Moreover, frosting of surface of eyeglasses is prevented by ensuring that the hot steam of breath or nose does not flow out towards the upper part of the Mask when the patient who wears eyeglasses wears eyeglasses. As a consequence, user of eyeglasses can wear the Mask, free of inconvenience, and the air-blocking material, comprised of light, soft and elastic material maintains the hanging string and both sides of the ears elastic. Accordingly, pain that might otherwise result from the pressing down of hanging string is prevented, which increases the comfortable feel of wearing the Mask. <IMAGE></p> |
