<P>PROBLEM TO BE SOLVED: To provide a mask with a filtration medium box capable of preventing air sucked into the mask from forming a customary path between particulate fillers inside the filtration medium box. <P>SOLUTION: In this mask with the filtration medium box, many particulate filler filtration media are equally arranged by utilizing a honey core and localized plywood installed inside the filtration medium box, the air sucked into the mask is prevented from forming the customary route between the particulate fillers inside the filtration medium box, the particulate filler filtration media inside the filtration medium box are made to uniformly demonstrate the function of filtering the sucked air, and the using service life of the mask is prolonged. Also, an appropriate space is secured between a case body inner surface and the mouth and nose of a mask user by utilizing a recessed space formed on the case body inner surface, a pressure is reduced by increasing the permeation area of cleaned air filtered in the filtration medium box, and the user can wear the mask with the filtration medium box for a long period of time and does not have so many problems in respiration. <P>COPYRIGHT: (C)2007,JPO&INPIT |
