  • Patent number: 7033340
    Abstract: The present invention provides a disposable absorbent article which does not substantially impact the surface tension of the acquired liquid and thus allows to combine good liquid acquisition performance with a liquid handling structure having large open pores. The disposable absorbent article of the present invention comprises the topsheet, a backsheet, the liquid storage structure intermediate the topsheet and the backsheet and a liquid handling structure intermediate the topsheet and the liquid storage structure. The liquid handling structure and features large open pores in order to readily accept high viscosity liquids such as faces as well as low viscosity liquids such as urine. The various components of the absorbent article of the present invention do not substantially reduce the surface tension of the acquired liquid.
