Claims (1)
外マスク部材を内外に重ね、各部材の周縁を連結
して連結部を形成することにより両マスク部材間
に蓄熱室を設け、内マスク部材及び上記の連結部
に呼吸に必要なだけの空気の流通を許容する通気
部を設け、上記の蓄熱室に熱交換部材を収納して
成る蓄熱式防寒マスク。 A shell-shaped inner mask member and an outer mask member made of a non-breathable material are stacked inside and outside, and the peripheral edges of each member are connected to form a connecting part, thereby providing a heat storage chamber between both mask members, and forming a heat storage chamber between the inner mask member and the outer mask member. A heat storage type cold protection mask comprising a ventilation section that allows the circulation of air as much as necessary for breathing in the connection part, and a heat exchange member stored in the heat storage chamber.
