发明名称 Protective article having a transparent shield
摘要 A shield that is configured for use with a mask to form a protective article. The mask includes (i) a central portion having a pair of opposed edges, (ii) a first portion joined to an edge of the central portion, and (iii) a second portion joined to the other edge of the central portion. At least one of the central, upper and lower portions is formed from filter media. The shield is flexible and transparent, having upper and lower edges, with the lower edge having at least one projection. It is dimensioned to cover the portion of the wearer's face not covered by the mask. The shield is adapted to be attached to the mask and moved between a first position in which the shield lower edge and the lower edge projection lies in front of the mask central portion, and a second position in which the lower edge projection engages the mask such that at least a portion of the shield lower edge lies behind the central portion.
