    摘要: Respirator and buckle having a flexural member allowing the buckle to move in three dimensions, potentially improving user comfort, the effectiveness of the respirator, and allowing for more precise adjustments to be made to the fit of the respirator on the user. The flexural member may be a three dimensional living hinge. By lifting on the buckle, the straps that secure the respirator to the user are released and the ability of the buckle to move in three dimensions tends to increase the situations in which the adjustment may occur. Various types of three dimensional living hinges may be utilized, including a cylindrical hinge and a serpentine hinge.

    摘要: Face masks that include a unidirectional valve are disclosed. The unidirectional valves permit fluid communication between an interior gas space defined by the mask and the wearer and an exterior gas space outside of the face mask. The unidirectional valves includes one or more valve flaps positioned over an opening formed in the base of the valve. Each of the valve flaps includes a free edge and a hinge located generally opposite from the free edge.
