Abstract
Abstract An absorbent structure for absorbing body fluid is provided having means to direct body fluid along the longitudinal axis of the product and to substantially limit side failure. Two or more longitudinal chambers of absorbent material are provided which are separated by fluid repellent walls. These walls act to guide flow generally along the longitudinal axis of the product.
