Abstract

A protective face masks including an anti-fog device for use on protective face masks, and more specifically, to devices anti-fog comprises a porous material made form low-density polyethylene (LDPE) and/or ethylene-vinyl acetate (EVA) having a density between 10 pores per inch and 60 pores per inch. Among other things, the disclosed inventions provide a barrier to prevent fogging of eyewear and other eyewear worn by a user when wearing the protective facemask.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An anti-fog protective mask device comprising:
 a protective mask configured to adhere to the face of a user wherein the protective mask includes an inner and outer surface and includes an upper, lower and side portion of the inner surface;   securing apparatus affixed to the protective mask to secure the protective mask to the face of a user; and   an anti-fog barrier affixed to the upper portion of the inner surface of the protective mask wherein the anti-fog barrier consists of a porous low-density foam material, the porous low-density foam material has a density of between 10 pores per inch to 40 pores per inch to reduce moisture from the breadth of the user to cause a fog on the eyewear of a user.   
     
     
         2 . The anti-fog protective mask device of  claim 1 , wherein the porous low-density foam material consists of a low-density polyethylene (LDPE). 
     
     
         3 . The anti-fog protective mask device of  claim 1 , wherein the porous low-density foam material further consists of low-density polyethylene (LDPE) and ethylene-vinyl acetate (EVA). 
     
     
         4 . The anti-fog protective mask device of  claim 2 , wherein the low-density polyethylene has a density of 10 pores per inch. 
     
     
         5 . The anti-fog protective mask device of  claim 2 , wherein the low-density polyethylene has a density of 30 pores per inch. 
     
     
         6 . The anti-fog protective mask device of  claim 2 , wherein the low-density polyethylene has a density of 40 pores per inch. 
     
     
         7 . The anti-fog protective mask device of  claim 3 , wherein the low-density polyethylene has a density of 10 pores per inch. 
     
     
         8 . The anti-fog protective mask device of  claim 3 , wherein the low-density polyethylene has a density of 30 pores per inch. 
     
     
         9 . The anti-fog protective mask device of  claim 3 , wherein the low-density polyethylene has a density of 60 pores per inch. 
     
     
         10 . The anti-fog protective mask of  claim 1 , further comprising an anti-fog barrier affixed to the protective mask about the side portions of the inner surface of the protective mask. 
     
     
         11 . The anti-fog protective mask of  claim 10 , further comprising an anti-fog barrier affixed to the protective mask about the lower portion of the inner surface of the protective mask. 
     
     
         12 . The anti-fog protective mask of  claim 2 , wherein, the low-density polyethylene is treated with an anti-fog coating. 
     
     
         13 . The anti-fog protective mask of  claim 3 , wherein, the low-density polyethylene and ethylene-vinyl acetate are treated with an anti-fog coating. 
     
     
         14 . The anti-fog protective mask of  claim 3 , wherein, the ethylene-vinyl acetate are treated with an anti-fog coating. 
     
     
         15 . The anti-fog protective mask device of  claim 1 , wherein the securing apparatus is affixed to the protective mask along the side portion of the protective mask wherein the securing mechanism is configured to fit around the ears of the user. 
     
     
         16 . The anti-fog protective mask device of  claim 15 , wherein the securing apparatus comprise elastic straps. 
     
     
         17 . The anti-fog protective mask device of  claim 16 , wherein the anti-fog barrier is securely affixed to the protective mask. 
     
     
         18 . The anti-fog protective mask device of  claim 17 , wherein the anti-fog material is sewn onto to the protective mask. 
     
     
         19 . The anti-fog protective mask device of  claim 15 , wherein the anti-fog barrier is removably affixed to the protective mask. 
     
     
         20 . The anti-fog protective mask device of  claim 19 , wherein the anti-fog barrier is removably affixed to the protective mask by means of an adhesive.
