Embodiment Construction

[0049]Features that are in common with surgical mask 10 shown in FIGS. 1-5 are designated with the same reference numerals.

[0050]Referring to FIG. 1, there is illustrated a perspective view of a surgical mask 10 having a surgical mask body 20 and a vapor barrier 30, shown in FIG. 6, disposed on a wearer 100 with glasses 200 according to an aspect of the present invention.

[0051]The surgical mask body 20 typically includes a plurality of layers, generally at least three layers (not shown), although some mask bodies may have only one or two layers.

[0052]Typically, at least one of the layers includes a thermoplastic material, for example, polypropylene. In some embodiments, the layers include an outer cover web, a filtering material, and a shaping layer. The outermost layer of the surgical mask is typically an outer cover web that is exposed to the exterior atmosphere when the mask is positioned on a wearer's face. If no cover web is present, an outer shell, for example, may be the oute...
