Mask

Abstract

A mask includes a main body part and a pair of ear straps. The main body part covers a wearer's mouth. The pair of ear straps are provided on both the left and right sides of main body part, and are hooked on the wearer's ears. The main body part has an upper end, a lower end, and an intermediate fixing point. The upper end fixing point is a part where an upper end part of each of the ear straps is fixed. The lower end fixing point is a part where a lower end part of each of the ear straps is fixed. The intermediate fixing point is a part where one location of an intermediate part of each of the ear straps is fixed. With respect to the main body part's vertical direction, the intermediate fixing point is located between the upper end and lower end fixing point.

         6 . The mask according to  claim 1 ,
 wherein the first intermediate fixing point exists on an inner surface of the main body part.   
     
     
         7 . The mask according to  claim 1 ,
 wherein the ear straps are fixed to the first intermediate fixing point of the main body part by stapling.   
     
     
         8 . The mask according to  claim 1 ,
 wherein the ear straps are fixed to the first intermediate fixing point of the main body part by hot-melt adhesion.   
     
     
         9 . The mask according to  claim 1 ,
 wherein the ear straps are fixed to the first intermediate fixing point of the main body part by ultrasonic welding.   
     
     
         10 . The mask according to  claim 1 ,
 wherein the main body part has a second intermediate fixing point which is a part where another location of the intermediate part of each of the ear straps is fixed; and   the second intermediate fixing point is located between the first intermediate fixing point and the lower end fixing point with respect to the vertical direction.   
     
     
         11 . The mask according to  claim 10 ,
 wherein the second intermediate fixing point is located in a vicinity of a side end of the main body part.   
     
     
         12 . The mask according to  claim 10 ,
 wherein the second intermediate fixing point is located closer to the lower end fixing point than the upper end fixing point.   
     
     
         13 . The mask according to  claim 12 ,
 wherein the ear straps extend between the second intermediate fixing point and the lower end fixing point without slack.   
     
     
         14 . The mask according to  claim 10 ,
 wherein a distance, in the vertical direction, from the second intermediate fixing point to the lower end fixing point is less than a distance, in the vertical direction, from the first intermediate fixing point to the upper end fixing point.   
     
     
         15 . The mask according to  claim 10 ,
 wherein the second intermediate fixing point exists on an outer surface of the main body part.   
     
     
         16 . The mask according to  claim 10 ,
 wherein the second intermediate fixing point exists on an inner surface of the main body part.   
     
     
         17 . The mask according to  claim 1 ,
 wherein the ear straps exhibit elasticity.   
     
     
         18 . The mask according to  claim 1 ,
 wherein the upper end fixing point and the lower end fixing point exist on an outer surface of the main body part.   
     
     
         19 . The mask according to  claim 1 ,
