FILTERING FACE-PIECE RESPIRATOR HAVING SUPPORT STRUCTURE INJECTION MOLDED TO FILTERING STRUCTURE |
摘要 |
A filtering face-piece respirator 10 that comprises a mask body 12 and a harness 14. The mask body 12 includes a supporting frame structure 16 and a filtering structure 18. The frame structure is injection molded onto the filtering structure 18 such that the frame structure 16 becomes bonded to the filtering structure 18. A mask body having such a support structure allows the filtering structure to follow its configuration closely, providing improved aesthetics and collapse resistance to the resulting article. |
