A sanitary napkin. The sanitary napkin comprises a central absorbent pad and flaps extending from each longitudinal edge of the central absorbent pad. The body of each flap contains a flexible axis about which the flap can fold on itself. The sanitary napkin preferentially bends at the line of juncture between each flap and the longitudinal edge of the central absorbent pad. When the sanitary napkin is in a panty for use, each flap bends upwardly at the lines of juncture between the flaps and the longitudinal edges of the central absorbent pad to form the base of a wall. This wall extends to the flexible axis in the body of the flap which is folded around the edge of the crotch portion of the panty. The sanitary napkin of the present invention provides effective protection to the user during the menstrual period by preventing body and clothing soiling while being comfortable to wear.
A sanitary napkin that is sized and configured to be worn in a user's panties which panties are so sized and configured that the crotch edge portions can be positioned in the user's groins while the crotch region of the panties noncompressively cover the user's labia majoria, said sanitary napkin comprising a longitudinally elongate absorbent core, a liquid barrier backsheet, and a pair of flexible side flaps, said core being sized and configured to only span across the distal surfaces of the user's labia majoria, and said flaps being sufficiently flexible and sized and configured to be so disposed in a user's panties that proximal portions of said flaps extend upwardly to the user's groins and cover the laterally outwardly facing surface areas of the user's labia majoria, and so that distal portions of said flaps extend downwardly from said user's groins and are disposed intermediate edge portions of said crotch region of the user's panties and areas of the user's inner thigh regions.
A laterally articulated sanitary napkin comprising an elongate central absorbent core having side edges, two proximal side panels having proximal and distal edges, and two distal side panels, said proximal side panels extending laterally outward from central portions of said side edges of said central absorbent core, and having said proximal edges coextensive therewith, and said distal side panels extending laterally outward from said distal edges of said proximal side panels, said sanitary napkin further comprising means for articulating said distal side panels relative to said proximal side panels, and means for being folded along the coextensive edge portions of said central absorbent core and said proximal side panels.
