| Abstract: |
A mask protects doctors, dentists and technicians, on the one hand, and their patients, on the other, from cross-contamination with various viruses and germs. The mask is inexpensive and hence disposable after a single use, if desired. Various types of visors fit on the head of the wearer. Fixed to the forward projecting edge of the visor is a shield which extends down to protect the eyes, nose and mouth and around the sides. The shield may be attached to the edge of the visor by adhesives such as glue, heat sealing, ultrasonic welding or other suitable means.
