Patent number: 7210482Abstract: A face mask structure has an upper mask portion, a middle mask portion, and a lower mask portion, which are formed integrally. The upper mask portion has an upper metal stripe disposed at a proper position thereof. The lower mask portion has a lower metal stripe disposed at a proper position thereof. The upper and lower mask portions are folded in opposite directions. When in use, the upper and lower mask portions are spread out to support the middle mask portion. In this way, the face mask structure becomes fitting in with the shapes of human faces. Furthermore, the middle mask portion has multiple folding portions. When in use, the folding portions are stretched out to increase filtering area. Thereby, the inner space of the face mask structure is increased, the air-invasion rate is reduced, and the filtering efficiency is thus improved.Type: GrantFiled: December 8, 2005Date of Patent: May 1, 2007Assignees: Taiwan Textile Research Institute, Champak Enterprise Co., Ltd.Inventors: Po-Hsiung Huang, Cheng-Kun Chu, Hung-En Chen, Jing-Tyr Lin, Jen-Hsiung Lee

Publication number: 20050098180Abstract: A mask with a three-dimensional structure provides a one-piece structure with an upper portion, the middle portion, and a lower portion. A molded notch is located at both nasal bridge of the upper portion and chin of the lower portion. The upper portion and lower portion are reversely folded so as to form a pleat for supporting the middle portion as a three-dimensional structure mask. The three-dimensional structure mask meets the facial configuration design for accommodating to different facial shapes. Furthermore, the mask with a three-dimensional structure has a normal range of elasticity to conform to certain facial contours, therefore, decreases leakage occurrence, and increases filtration rate in a high pollution environment. More, the upper portion and the lower portion of the mask are folded in a reverse direction for avoiding a contacting pollution from touching the inner surface.Type: ApplicationFiled: March 25, 2004Publication date: May 12, 2005Inventors: Jung-Shen Lien, Po Huang, Hung-En Chen, Jen-Hsiung Lee, Jing-Tzu Lin
