Abstract

A disposable sanitary garment includes a chassis defining an outer surface thereof, the chassis is provided along its transversely opposite side edge portions destined to extend around a wearer'"'"'s thighs with a pair of first leg-hole elastic members extending circumferentially around the thighs and with a pair of second leg-hole elastic members describing a circular arc being convex inwardly of the garment. The chassis is folded back inwardly of the garment along one side edges of the respective members with the second leg-hole elastic members inside and a portion of the chassis extending inside the zone along which the chassis has been first folded back is folded back along the other side edges of the respective members.

Claims

1. A disposable sanitary garment having inner and outer surfaces, comprising:

a chassis which defines said outer surface and includes transversely opposed side edge portions which circumferentially extend around a wearer'"'"'s thighs;

a pair of first leg-hole elastic members which extend along edges of said side edge portions circumferentially around the wearer'"'"'s thighs; and

a pair of second leg-hole elastic members which extend from said edges of said side edge portions along circular arcs that are convex inwardly of a crotch region,

said chassis being folded back inwardly of said garment along said second leg-hole elastic members so as to wrap around at least two opposite sides of said second leg-hole elastic members and form a folded zone,

a portion of said chassis which extends inside the folded zone being folded back again outwardly of said garment.

2. The garment according to claim 1, wherein portions of said chassis are folded around and extend on opposite sides of said first and second leg-hole elastic members and are bonded to each of said first and second leg-hole elastic members.

3. The garment according to claim 1, wherein a liquid-absorbent core lies on the inner surface of said chassis between said pair of second leg-hole elastic members.

4. A disposable sanitary garment having inner and outer surfaces, comprising:

a chassis which defines said outer surface and includes transversely opposed side edge portions which circumferentially extend around a wearer'"'"'s thighs;

a pair of first leg-hole elastic members which extend along edges of said side edge portions circumferentially around the wearer'"'"'s thighs;

a pair of second leg-hole elastic members which extend from said edges of said side edge portions along circular arcs that are convex inwardly of a crotch region; and

a liquid absorbent core,

said chassis being folded back inwardly of said garment along said second leg-hole elastic members so as to wrap said second leg-hole elastic members and form a folded zone,

a portion of said chassis which extends inside the folded zone being folded back again outwardly of said garment,

each of said pair of said first leg-hole elastic members and said pair of second leg-hole elastic members being spaced apart transversely outwardly from side edges of the liquid absorbent core.

5. A disposable sanitary garment having inner and outer surfaces, comprising:

a chassis which defines said outer surface and includes transversely opposed side edge portions which circumferentially extend around a wearer'"'"'s thighs;

a pair of first leg-hole elastic members which extend along edges of said side edge portions circumferentially around the wearer'"'"'s thighs;

a pair of second leg-hole elastic members which extend from said edges of said side edge portions along circular arcs that are convex inwardly of a crotch region; and

a liquid absorbent core,

said chassis being folded back inwardly of said garment along said second leg-hole elastic members so as to wrap said second leg-hole elastic members and form a folded zone,

a portion of said chassis which extends inside the folded zone being folded back again outwardly of said garment, said portion of the chassis that is folded back again is spaced transversely outwardly from side edges of the liquid absorbent core.
