Face covering with separator

Abstract

A face covering includes an upper portion and a lower portion, a separator disposed between the upper portion and the lower portion, and a strap coupled to the separator. The separator includes a front portion and a rear portion. The strap pulls the separator toward a face to make a part of the rear portion of the separator contact the face when the face covering is secured over the face.

What is claimed is: 
     
         1 . A face covering, comprising:
 an upper portion and a lower portion;   a separator disposed between the upper portion and the lower portion, the separator including a front portion and a rear portion; and   a strap coupled to the separator, the strap pulling the separator toward a face to make a part of the rear portion of the separator contact the face when the face covering is secured over the face.   
     
     
         2 . The face covering of  claim 1 , wherein a length of the part of the rear portion contacting the face is equal to or greater than 50% of the entire length of the rear portion. 
     
     
         3 . The face covering of  claim 1 , wherein the part of the rear portion of the separator directly contacts the face. 
     
     
         4 . The face covering of  claim 1 , wherein the strap is formed of a single string and the string includes a left portion, a middle portion, and a right portion, the middle portion passing through the rear portion of the separator. 
     
     
         5 . The face covering of  claim 4 , wherein the front portion of the separator includes one or more of polypropylene fabric, vinyl fabric, and silicon rubber. 
     
     
         6 . The face covering of  claim 5 , wherein the rear portion of the separator includes cotton. 
     
     
         7 . The face covering of  claim 1 , further comprising:
 a coupler coupling the strap to the face covering,   wherein the front portion of the separator is coupled to an inside surface of the face covering along a contact line, a reference line connecting the coupler and a middle point of a center line that vertically bisects the face covering, a first angle between the contact line and the reference line being in a range from −10° to 10° seen in a side view when the face covering is folded along the center line.   
     
     
         8 . The face covering of  claim 7 , wherein a virtual line connects the coupler and a middle tip of the separator, a second angle between the reference line and the virtual line being in a range from 15° to 35° seen in the side view when the face covering is folded. 
     
     
         9 . The face covering of  claim 1 , further comprising:
 two couplers coupling the strap to the face covering and being disposed opposite to each other with respect to a plane, the plane including a center line and vertically bisecting the face covering, a first point being a middle point in a line connecting the couplers,   wherein the front portion of the separator is coupled to an inside surface of the face covering along a contact line, a projected line being obtained by projecting the contact line onto the plane, a reference line connecting the first point and a middle point of the center line, a first angle between the projected line and the reference line being in a range from −10° to 10°.   
     
     
         10 . The face covering of  claim 9 , wherein a virtual line connects the first point and a middle tip of the separator, a second angle between the reference line and the virtual line being in a range from 10° to 30°. 
     
     
         11 . The face covering of  claim 1 , wherein the face covering is a face mask.
