Abstract:
An extensible sanitary napkin for wearing in the crotch region of an undergarment, said sanitary napkin having a longitudinal centerline, a transverse centerline, a longitudinal dimension extending in a longitudinal direction, a transverse dimension that is shorter than said longitudinal dimension, said transverse dimension extending in a transverse direction, and regions of differential extensibility, said sanitary napkin comprising a liquid pervious side, a liquid impervious side, and an absorbent core positioned between said liquid pervious side and said liquid impervious side, wherein said regions of differential extensibility comprise:a region of first extensibility having a first initial length and a first extended dimension, said region of first extensibility being capable of extension in the longitudinal direction between about 115% to about 150% of its first initial length when subjected to a force of between about 50 grams and about 1,500 grams;a region of second extensibility having a second initial length and a second extended dimension, said region of second extensibility being capable of extension in the longitudinal direction between about 115% to about 150% of its second initial length when subjected to a force of between about 50 grams and about 1,500 grams;wherein the force required to extend said region of second extensibility a given distance is less than the force required to extend said first region the same distance in the longitudinal direction.
