<p>A three dimensional face mask comprises: a three dimensional cup (10), a three dimensional soft rubber washer (20), an elastic tape (30), and an anti-skid band (40); it is characterized in that: the three dimensional cup (10) is made by hot pressing of multilayer of filtration material, the three dimensional soft rubber washer (20) is provided with a soft nose cushion (21) and is bonded to an outer periphery (11) of the three dimensional cup (10) by hot pressing, the anti-skid band (40) is bonded to a lower edge of the three dimensional cup (10), the elastic tape has two ends symmetrically bonded to both sides of the three dimensional cup. The three dimensional non-woven face mask ensures a good air tightness against the face while leaving a large enough space between the three dimensional cup and the nose and mouth area to ensure conformable wearing, good filtration, making the wearer easy to breathe and talk.</p> |
