Abstract: A respirator is described in which the shell portion joins the filter mat by a unique juncture wherein portions of the filter mat are mechanically bonded to the material of the shell and other portions of the mat may be attached by welding or chemical bonding to the material of the shell. The mechanical bonding is obtained by molding the shell into and around the edges of the filter mat. The welding is obtained by the incorporation of selected materials in the filter that heat weld to the material of the shell when the latter is molded about the former. The materials of shell and filter mat may be chosen to be pliant and flexible thereby providing a respirator that is adaptable to the static and dynamic facial contours of the user. Because of the molded construction of the respirator, it can be made at a low cost. In the manufacture of the filter mat shell joint, it is important that the mat be sealed off at the boundary of the joint area to prevent molten shell material from penetrating too far into the filter mat.
Abstract translation: 描述了一种呼吸器，其中外壳部分通过一个独特的接合处将过滤垫连接在一起，其中过滤垫的部分机械地结合到壳的材料并且垫的其它部分可以通过焊接或化学粘合附着到材料 贝壳。 通过将壳体模制到过滤垫的边缘中和周围来获得机械结合。 焊接是通过将所选择的材料结合到过滤器中而获得的，当过滤器围绕前者模制时，热焊接到壳体的材料。 外壳和过滤垫的材料可以被选择为柔韧和灵活的，从而提供适于使用者的静态和动态面部轮廓的呼吸器。 由于呼吸器的模制结构，可以以低成本制造。 在过滤垫壳接头的制造中，重要的是在接合区域的边界处密封垫，以防止熔融壳材料渗透到过滤垫中太远。
