  • Patent number: 6953451
    Abstract: A sanitary napkin for placement in a crotch portion of an undergarment of a wearer having a longitudinal axis and being further characterized by having a preferential bending zone extending obliquely in relation to the longitudinal axis, each preferential bending zone being located solely in an end region and does not extend into a central region of the napkin. The preferential bending zone may be created by mechanically embossing the surface of the sanitary napkin to locally densify the absorbing materials of the article. The preferential bending zone causes the end regions of the sanitary napkin to resist lateral compression forces exerted by the thighs of the wearer and thereby prevents bunching of the article on the undergarment. The central region 70 of the sanitary napkin conforms to the wearer's body providing greater comfort for the wearer of the napkin.
