A sanitary napkin which deforms to a convex upwardly shaped cross section. The sanitary napkin has a line of weakness which is symmetric about the longitudinal axis and longitudinally concave towards the lateral centerline. In a preferred embodiment, the line of weakness is discontinuous and comprises discrete sites joining the topsheet and core. The discrete sites may be bilaterally staggered about the line of weakness T.

L'invention se rapporte à une serviette hygiénique qui se déforme pour prendre dans sa section transversale une configuration convexe vers le haut. La serviette hygiénique présente une ligne d'affaiblissement qui est symétrique par rapport à l'axe longitudinal et longitudinalement concave vers la ligne médiane latérale. Dans un mode préféré de réalisation, la ligne d'affaiblissement est discontinue et comporte des points séparés réunissant la feuille supérieure et la partie centrale. Les points séparés peuvent être échelonnés de manière bilatérale par rapport à la ligne d'affaiblissement T.
