Anti-fog mask for blocking exhaled breath

Abstract

Proposed is an anti-fog mask for blocking exhaled breath from the nose and mouth of a wearer from moving upwardly from an upper portion of the mask through a gap between a mask body inner surface and the curved part of the wearer's face between the bridge of the nose and the cheeks of the wearer, thereby preventing fogging on surface of lenses of glasses or goggles of the wearer. The anti-fog mask includes a mask body including at least one mask body inner surface, at least one mask body outer surface, and at least one mask body filter surface, a plastic film adhesive part formed on the mask body inner surface at an upper end of the mask body inner surface, a plastic fixing member formed on the mask body at the upper end of the mask body and deformable by an external force, and a pair of straps.

1 . An anti-fog mask comprising:
 a mask body comprising at least one mask body inner surface, at least one mask body outer surface, and at least one mask body filter surface;   a plastic film adhesive part formed horizontally on the mask body inner surface at a longitudinal upper end of the mask body inner surface, and composed of a film made of polyethylene and having a thickness in a range of 2.5 to 30 μm and a specific gravity in a range of 0.80 to 0.95;   a plastic fixing member formed horizontally on the mask body at the longitudinal upper end of the mask body and configured to be deformable by an external force; and   a pair of mask straps.   
     
     
         2 . The anti-fog mask of  claim 1 , further comprising an elastic member blocking part formed horizontally on the mask body. 
     
     
         3 . The anti-fog mask of  claim 1 , wherein the film of the plastic film adhesive film part formed on the mask body inner surface has a thickness of 2.5 to 20 μm.
