    Abstract: Various embodiments of an exhalation valve and a filtering face mask that includes such exhalation valve are disclosed. The exhalation valve can include a valve seat and a valve flap disposed over a seal surface and an orifice of the valve seat. The valve flap is adapted to be sealed against the seal surface of the valve seat when the exhalation valve is disposed in a closed configuration such that fluid is prevented from flowing through the valve seat. The orifice of the valve seat can include a substantially circular shape in a plane defined by a first major surface of the valve seat. Further, the seal surface can circumscribe the orifice and can include a substantially noncircular shape in the plane defined by the first major surface of the valve seat.

    Abstract: The present invention relates to a sealing foam, a respirator, and a method for manufacturing a sealing foam. The sealing foam includes: a main body part, the main body part being a porous foam; an air-proof film on a continuous surface; and an anchor layer, the anchor layer being continuously provided on the upper layer of the main body and provided between the air-proof film and the main body part, and the anchor layer being partially embedded in pores of the porous foam. The respirator includes a respirator main body and a sealing foam of the present invention. The method for manufacturing a sealing foam includes: providing a porous foam to prepare a main body part of a sealing foam, and providing an anchor layer and an air-proof film on the porous foam, so that the air-proof film is continuously provided on an upper surface of the main body part, wherein the anchor layer is provided between the air-proof film and the main body part, and is partially embedded in pores of the porous foam. The sealing foam, the respirator, and the method for manufacturing a sealing foam according to the present invention are convenient for subsequent cutting, can simplify the manufacturing process of the sealing foam, improve the sealing between the respirator and the face of a wearer, and improve the wearing comfort of the respirator.

    Abstract: Various embodiments of a respirator are disclosed. The respirator can include a mask body and one or more elastic straps that are secured to the mask body on opposing sides. The elastic straps can have an openwork construction and can include a netting that has an array of polymeric strands periodically joined together at bond regions throughout the array. In one or more embodiments, the openwork elastic straps are lighter and more breathable than conventional straps. This improvement in breathability can make the respirator more comfortable to wear.

    Abstract: The present invention relates to a sealing strip, a respirator, and a method for manufacturing a sealing strip. The sealing strip includes a main body part, the main body part having an upper surface, a lower surface, a first side surface, and a second side surface opposite to the first side surface. The main body part includes a curved surface part. The curved surface part includes a first convex part and a second convex part, and the first convex part and the second convex part are connected to each other in the lengthwise direction of the sealing strip to define a concave part located therebetween. The concave part is configured to accommodate the nose of a wearer. The first convex part and the second convex part are symmetrical about the concave part. A first side surface of the curved surface part is a sinusoidal curved surface with a constant amplitude extending in the lengthwise direction of the sealing strip. By the sealing strip, the respirator and the method for manufacturing a sealing strip according to the present invention, a manufacturing process of the sealing strip can be simplified; a maximum utilization rate of materials can be achieved; sealing between the respirator and the face of the wearer can be improved, and the wearing comfort of the respirator can be increased.
