Abstract:
A sanitary absorbent article comprising:a main body, said main body having two opposing longitudinal side portions, two opposing transverse side portions, an imaginary longitudinal centerline and an imaginary transverse centerline, said main body including: a fluid-pervious cover layer, said fluid-pervious cover layer facing towards a wearer's body when the sanitary absorbent article is in use by the wearer; a liquid-impervious barrier layer, said liquid-impervious barrier layer facing away from the wearer's body when the sanitary absorbent article is in use by the wearer; an absorbent system intermediate said fluid-pervious cover layer and said liquid-impervious barrier layer; wherein said sanitary absorbent article includes at least one flap projecting laterally from a longitudinal side portion of said main body, said flap connecting with said main body through an area of juncture said fluid-pervious cover layer and said liquid-impervious barrier joined to one another to form a flange seal extending along at least a portion of a peripheral edge margin of said absorbent system; at least a portion of said flange seal laying in an imaginary plane in the area of juncture between the flap and the longitudinal side portion and including an outer edge portion and an inner edge portion, said inner edge portion residing closer to said absorbent system than said outer edge portion; the portion of said flange seal laying in said imaginary plane in the area of juncture between the flap and the longitudinal side portion including a first zone and a second zone separated from one another by a common boundary, an imaginary reference line laying in said imaginary plane and extending in a direction from said outer edge portion to said inner edge portion intersecting said first zone before said second zone; and said first zone manifesting a higher resistance to shear stress than said second zone.
