  • Patent number: 5615767
    Abstract: A package for holding and dispensing surgical masks, respirators, face shields and other articles having eye shields made from a substantially transparent, flexible material susceptible to abrasion or scratching. The surgical masks are stacked within the container one upon another and a fanning force is applied to each eye shield such that the eye shields become semi-rigid and fan apart, one from the next in the stack. In such condition scratching caused by the eye shields rubbing against each other is virtually eliminated, and the surgical masks are dispensed in a convenient scratch-free manner.
