Multi-layer face mask with foamed in place edge member
First Claim
1. A facemask to be worn upon the face of a wearer and for providing filtering of particular impurities in the air, including at least one layer of flexible material to conform to the contours of the face of the wearer including the areas of the sides of the nose, the bridge of the nose and upper cheekbones and forming a flexible support carrier for filter material and with the at least one layer of flexible material allowing the passage of air through the one layer, a separate layer of filter material supported by the at least one layer of flexible material and with the filter material filtering out the particular impurities in the air, and a foamed in place deformable edge member extending at least partially around the peripheral edges of the at least one layer of flexible material and the separate layer of filter material forming the facemask and with the foamed in place deformable member providing an edge seal between the facemask and the face of the wearer.

Abstract
A facemask to be worn upon the face of a wearer and for providing filtering of particular impurities in the air, including at least one layer of flexible material to conform to the contours of the face of the wearer and forming a flexible support carrier for filter material and with the one layer of flexible material allowing the passage of air through the one layer, a separate layer of filter material supported by the one layer of flexible material and with the filter material filtering out the particular impurities in the air, a foamed in place deformable edge member extending around the peripheral edge of the layers forming the facemask and with the foamed in place deformable edge member providing an edge seal between the facemask and the face of the wearer, and the foamed in place member including additional deformable portions extending inwardly to the interior of the mask from the foamed in place edge member at least in the areas of the sides of the nose and upper cheekbones of the wearer for providing additional sealing in those areas.
