Abstract

The present invention provides a protective face mask comprising an inner mask layer, an outer mask layer and a foam frame disposed between the respective mask layers. Two opposing elastic ear straps are configured to loop around the wearer's ears to secure the protective mask to the wearer's face and the resultant tension directs pressure through the foam frame and exerts force to press the inner mask or a filtration material layer against the wearer's face, thus creating an effective seal. The inner and outer mask layers, and the foam frame positioned therebetween, provide enhanced protection from potentially harmful airborne pathogens and provide a barrier to undesirable fluid, aerosol and particulate transfer

Claims

exact text as granted — not AI-modified
1 . A protective mask comprising:
 an outer mask layer;   an inner mask layer comprised of a single unitary piece of material that covers a user's mouth and nose;   a foam frame disposed between and adhered to the outer mask layer and the inner mask layer; and   ear straps fixed to opposing ends of the outer mask layer for securing the outer mask layer to a wearer's face.   
     
     
         2 . A protective mask according to  claim 1 , wherein said outer mask layer and inner mask layer are comprised of a flexible material. 
     
     
         3 . A protective mask according to  claim 1 , wherein said outer mask layer and inner mask layer are comprised of polypropylene. 
     
     
         4 . A protective mask according to  claim 1 , wherein said outer mask layer further comprises a moldable nose wire configured for rendering the foam frame in a shape that corresponds with a nasal bridge region of the wearer's face. 
     
     
         5 . A protective mask according to  claim 1 , wherein said foam frame further comprises a nasal bridge region shaped to conform the foam frame to the bridge of the wearer's nose. 
     
     
         6 . A protective mask according to  claim 1 , wherein said protective mask further comprises a vapor barrier affixed to a top portion of the foam frame. 
     
     
         7 . (canceled) 
     
     
         8 . (canceled)

         13 . (canceled) 
     
     
         14 . A protective mask comprising:
 an outer mask layer;   an inner mask layer comprised of a single unitary piece of material and having a single cut-out hole corresponding to a user's mouth and nose;   a foam frame disposed between and adhered to the outer mask layer and the inner mask layer; and   ear straps fixed to opposing ends of the outer mask layer for securing the outer mask layer to a wearer's face,
 wherein said inner mask layer, outer mask layer and foam frame are bonded together in three layers, forming a pillow-like structure of the protective mask. 
   
     
     
         15 . A protective mask according to  claim 14 , wherein said inner mask layer, outer mask layer and foam frame are thermally bonded. 
     
     
         16 . A protective mask according to  claim 14 , wherein a plastic wrap material is affixed to said foam frame to provide a vapor seal. 
     
     
         17 . A protective mask according to  claim 14 , wherein said outer mask layer and inner mask layer are comprised of polypropylene. 
     
     
         18 . A protective mask according to  claim 14 , wherein said outer mask layer further comprises a moldable nose wire configured for rendering the foam frame in a shape that corresponds with a nasal bridge region of the wearer's face. 
     
     
         19 . A protective mask according to  claim 14 , wherein said foam frame further comprises a nasal bridge region shaped to conform the foam frame to the bridge of the wearer's nose. 
     
     
         20 . A protective mask comprising:
 an outer mask;   an inner filter material sheet having a single cut-out hole corresponding to a user's mouth and nose; and   a foam frame disposed between said outer mask and said inner filter material sheet,
 wherein said outer mask and said inner filter material sheet are bound together at their respective perimeters, forming a unitary mask assembly having an internal pocket formed between said outer mask and said inner filter material sheet, which houses said foam frame. 
   
     
     
         21 . (canceled) 
     
     
         22 . A protective mask according to  claim 20 , wherein said foam frame is adhered to said inner filter material sheet. 
     
     
         23 . A protective mask according to  claim 20 , wherein said outer mask and said inner filter material sheet are comprised of multiple filtration layers. 
     
     
         24 . A protective mask according to  claim 14 , wherein said single cut-out hole is substantially rectangular-shaped.
