发明名称 Face mask with liquid and glare resistant visor
摘要 A clear plastic visor (16) is secured to a mask (12) which is removably attachable to the face of a wearer. The visor (16) is secured to the mask (12) at bond areas (48, 50) on opposite ends of the mask (12). The visor (16) is provided with a notched keyhole (20) to allow the visor (16) to conform to contours of the face of the wearer and to prevent creasing thereof. The visor (16) is generally positioned on the mask (12) so that approximately 1/3 of the visor's depth (D) covers the mask (12). A darkened strip (22) may be added to the top edge of the mask (12) to further reduce the likelihood of glare and reflections.
