发明名称 RESPIRADOR ISENTO DE MANUTENÇÃO
摘要 A respirator 10 that has a mask body 12 that has a plurality of panels 16, 18, 20 that can fold in towards each other and that can unfold into open in-use configuration. At least one of the panels has a tab 22 that assists in opening the mask body 12 from its folded configuration into its open in-use configuration. The use of the tab 22 on the panel(s) of the multi-paneled mask body 12 allows for easier donning and doffing and reduces the opportunity for contaminants to get into the mask interior when the mask is being opened by the user.
