Disclosed is an absorbent article, such as a sanitary napkin, incontinent device, or the like. The absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core disposed between the topsheet and the backsheet. The absorbent article further comprises a pair of longitudinally extending bands of web material disposed on the body surface of the topsheet on each side of a longitudinal centerline of the absorbent article and joined to at least one of the topsheet and the backsheet in a longitudinally elastically elongated state. The bands of web material comprise first and second regions which are visibly distinct from each other. The first region comprises at least two substantially planar portions and the second comprises a plurality of raised, rib-like elements. In a particularly preferred embodiment of the present invention, at least one of the substantially planar portions of the first region of the bands of web material extends in a substantially longitudinal direction and at least one other of the substantially planar portions of the first region of the bands of web material is oriented at an angle with respect to the longitudinal direction. Alternative embodiments of the present invention can be further provided with flaps positioned at least in a middle region of the absorbent article and which extend laterally outward from a side edge of a central absorbent body.

L'invention porte sur un article absorbant du type serviette hygiénique ou couches pour incontinents comportant une feuille de couverture perméable aux liquides, une feuille de support imperméable aux liquides et un noyau absorbant situé entre les deux. Ledit article comprend en outre une paire de bandes de matériau disposées à la surface de la feuille de couverture de part et d'autre de l'axe longitudinal de l'article absorbant et fixées au moins à la feuille de couverture ou à la feuille de support à l'état d'étirement élastique longitudinal. Par ailleurs, les bandes de matériau comportent une première et une deuxième zone visiblement distinctes l'une de l'autre dont la première comporte au moins deux parties sensiblement planes et la deuxième, une série de nervures en saillie. Dans l'une des réalisations particulièrement conseillée, l'une au moins des parties sensiblement planes de la première zone de la bande s'étend dans une direction sensiblement longitudinale, et l'une au moins des parties sensiblement planes de la première zone de la bande s'étend dans une direction sensiblement oblique par rapport à l'axe longitudinal. Il existe différentes variantes de l'invention munies de rabats disposés au moins au centre de l'article et s'étendant latéralement vers l'extérieur à partir des bords latéraux du centre de l'article.
