Steam heating mask

Abstract

Provided is a steam heating mask (100) that includes a mask (110) which includes a mask body portion (101) covering a nose and a mouth of a wearer when wearing the mask, and a pair of ear hook portions (102) provided at both left and right ends of the mask body portion (101), and a steam generator (120) on the mask body portion (101), in which a proportion of an area occupied by the steam generator (120) is equal to or greater than 30% and equal to or less than 80% with respect to an area of an entire surface of the mask body portion (101) on a side of the wearer, the steam generator (120) accommodates inside a steam generating portion, the steam generator (120) includes a first sheet on a surface of the steam generating portion on the side of the wearer, and a second sheet on a surface opposite to the surface of the steam generating portion on the side of the wearer, a degree of air permeability of the first sheet is equal to or less than 7,000 sec/100 ml, and a degree of air permeability of the second sheet is greater than 8,000 sec/100 ml.

1 . A steam heating mask comprising:
 a mask that includes a mask body portion covering a nose and a mouth of a wearer when wearing the mask, and a pair of ear hook portions provided at both left and right ends of the mask body portion; and   a steam generator on the mask body portion,   wherein a proportion of an area occupied by the steam generator is 30% to 80% with respect to an area of an entire surface of the mask body portion on a side of the wearer,   the steam generator accommodates a steam generating portion therein,   the steam generator includes a first sheet on a surface of the steam generating portion on the side of the wearer, and a second sheet on a surface, opposite to the surface on the side of the wearer, of the steam generating portion,   a degree of air permeability of the first sheet is equal to or less than 7,000 sec/100 ml,   a degree of air permeability of the second sheet is greater than 8,000 sec/100 ml, and
 wherein a stiffness value of the steam generator in a vertical direction is equal to or greater than 30 gf/60 mm width. 
   
     
     
         2 . A steam heating mask comprising:
 a mask that includes a mask body portion covering a nose and a mouth of a wearer when wearing the mask, and a pair of ear hook portions provided at both left and right ends of the mask body portion; and   a steam generator on the mask body portion,   wherein a proportion of an area occupied by the steam generator is 30% to 80% with respect to an area of an entire surface of the mask body portion on a side of the wearer,   the steam generator accommodates a steam generating portion therein,   the steam generator includes a first sheet on a surface of the steam generating portion on the side of the wearer, and a second sheet on a surface, opposite to the surface on the side of the wearer, of the steam generating portion,   a degree of air permeability of the second sheet is equal to or greater than 250 sec/100 ml and equal to or less than 8,000 sec/100 ml,   a degree of air permeability of the first sheet is equal to or less than 20% with respect to the degree of air permeability of the second sheet, and   
       wherein a stiffness value of the steam generator in a vertical direction is equal to or greater than 30 gf/60 mm width.
