Panty

Abstract

The invention provides a panty realizing easy fit of a sanitary napkin for night use to a crotch portion, preventing the napkin from shifting out of position, alleviating digging into the crotch portion, and thus being comfortable to wear without giving feeling of constriction to the wearer. The panty includes a front part, a back part, a crotch part provided so as to bridge between the front part and the back part, a slightly elastic member is provided at the substantially center area of the back part, a highly elastic member is provided from a back parts lifting member to the entire area of the front part except for the waist hold part, a fixing member is provided on the substantially center area of the front part, a crotch lifting member is provided at the substantially center area of the crotch part.

       2 . A panty according to  claim 1 , wherein a longitudinal elastic coefficient of the slightly elastic member is larger than a longitudinal elastic coefficient of the highly elastic member.  
   
   
       3 . A panty comprising: 
 a front part; a back part; a crotch part provided so as to bridge between the front part and the back part, the crotch part being utilized for fitting a sanitary napkin; a waist opening part provided in an upper edge of the front part and an upper edge of the back part; and a pair of leg openings provided below both side edges of the front part and both side edges of the back part,    wherein a napkin lifting part is provided in a middle of the crotch part from the front part to the back part, and a longitudinal elastic coefficient of the napkin lifting part is larger than a longitudinal elastic coefficient of a crotch cloth constituting the crotch part.    
   
   
       4 . A panty comprising: 
 a front part; a back part; a crotch part provided so as to bridge between the front part and the back part, the crotch part being utilized for fitting a sanitary napkin; a waist opening part provided in an upper edge of the front part and an upper edge of the back part; a pair of leg openings provided below both side edges of the front part and both side edges of the back part; and a slightly elastic member made of a slightly elastic material provided in a highly elastic member made of a highly elastic material,    wherein the slightly elastic member is provided in a substantially center area of the back part from the crotch part to the waist opening part,    a napkin lifting part is provided in a middle of the crotch part from the front part to the back part,    the slightly elastic member and the napkin lifting part are stitched together at an end of the crotch part on the side of the back part,    a longitudinal elastic coefficient of the slightly elastic member is larger than a longitudinal elastic coefficient of the highly elastic member, and    a longitudinal elastic coefficient of the napkin lifting part is larger than a longitudinal elastic coefficient of a crotch cloth constituting the crotch part.    
   
   
       5 . The panty according to  claim 1 , wherein the crotch part is formed by providing the crotch cloth stitched with the front part and with the back part.  
   
   
       6 . The panty according to  claim 1 , wherein the panty further comprises a waist hold part provided around the waist opening part extending from the back part to the front part.  
   
   
       7 . The panty according to  claim 1 , wherein the panty comprises a fixing member in a substantially center area of the front part stitched on the crotch part, the waist hold part, and the highly elastic member on an external side of the highly elastic member.  
   
   
       8 . The panty according to  claim 1 , wherein the slightly elastic member is formed of a material which is non-elastic in a longitudinal direction.  
   
   
       9 . The panty according to  claim 3 , wherein the napkin lifting part is formed of a material which is non-elastic in the longitudinal direction.  
   
   
       10 . The panty according to  claim 3 , wherein the longitudinal elastic coefficient of the napkin lifting part is smaller than the longitudinal elastic coefficient of the slightly elastic member.  
   
   
       11 . The panty according to  claim 3 , wherein a width of the napkin lifting part is tapered from the front part to the back part.  
   
   
       12 . The panty according to  claim 11 , wherein the width of the napkin lifting part ranges between 20 mm and 60 mm.  
   
   
       13 . The panty according to  claim 7 , wherein the longitudinal elastic coefficient of the fixing member is larger than the elastic coefficient of the highly elastic member in the longitudinal direction.  
   
   
       14 . The panty according to  claim 1 , wherein an upper end of the slightly elastic member on a side of the waist opening part is stitched with the waist hold part in substantially V-shape.  
   
   
       15 . The panty according to  claim 6 , wherein an upper end of the fixing member on a side of the waist opening part is stitched with the waist hold part in substantially V-shape.  
   
   
       16 . The panty according to  claim 1 , wherein the crotch part comprises a napkin fitting cloth inside, front and rear ends of the napkin fitting cloth being stitched with the crotch part and side ends of the napkin fitting cloth being unstitched on the crotch part.  
   
   
       17 . The panty according to  claim 16 , wherein a length of the napkin fitting cloth is equivalent to or longer than a length of the crotch cloth constituting the crotch part.  
   
   
       18 . The panty according to  claim 1 , wherein an elasticity gradually decreases from the highly elastic member to the slightly elastic member at a boundary between the highly elastic member and the slightly elastic member.  
   
   
       19 . The panty according to  claim 1 , wherein an elasticity changes discontinuously from the highly elastic member to the slightly elastic member at a boundary between the highly elastic member and the slightly elastic member.
