The present invention provides an absorbent article such as a diaper, a training pant, an adult incontinence article, a bed mat, or the like which is capable of evenly storing urine in a first storage region and in a second storage region. In particular, the fraction of the amount of liquid stored in the first storage region to the amount of liquid stored in the second storage region remains relatively unchanged over a wide range of loadings of the article. The present invention further provides a process for handling urine in the absorbent article which comprises a step of storing liquid in a first storage region and of storing, liquid in a second storage region such that the ratio of the amount of liquid stored in the first storage region to the amount of liquid stored in the second storage region remains relatively constant over a wide range of loadings of the article.

1. An absorbent article, said article comprising an acquisition region, a first storage region being separate from said acquisition region, and a second storage region being separate from said acquisition region, said second storage region being symmetrically different from said first storage region
1. An absorbent article, said article comprising an acquisition region, a first storage region being separate from said acquisition region, and a second storage region being separate from said acquisition region, said second storage region being symmetrically different from said first storage region, wherein said article has a fill pattern difference of less than 30% according to the fill ratio test disclosed herein. 2. An absorbent article according to claim 1 said article further comprising a liquid transport member transporting liquids from said acquisition region to said first storage region and to said second storage region. 3. An absorbent article according to claim 2, wherein said liquid transport member is substantially geometrically saturated before the intended use of said article. 4. An absorbent article according to claim 1, wherein said article is a disposable absorbent article. 5. An absorbent article according to claim 4, wherein said article is a disposable diaper. 6. A process for storing urine in an absorbent article, said article having an acquisition region, a first storage region being separate from said acquisition region, and a second storage region being separate from said acquisition region and being symmetrically different from said first storage region said process for storing body fluids comprising the steps of acquiring liquid into said article at said acquisition region, the amount of liquid acquired into said acquisition region being a fraction A of the total design capacity of said article for managing urine, storing liquid in a first liquid storage region, the amount of liquid being stored in said first liquid storage region being a fraction B1 of said acquired liquid, said fraction B1 being at least 10%, storing liquid in a second liquid storage region, the amount of liquid being stored in said second liquid storage region being a fraction B2 of said acquired liquid, said fraction B2 being at least 10% wherein for any value of said fraction A between 20% and 80% the ratio of B1/B2 differs by less than 30% from the ratio of B1/B2 for a fraction A of 20%. 7. A process for storing urine according to claim 6 wherein said article further comprises a liquid transport member and wherein said process further comprises the steps of transporting at least a portion of said acquired liquid to said first liquid storage region transporting at least a portion of said acquired liquid to said second liquid storage region said transportation steps being carried out by said liquid transport member. 8. A process for storing urine according to claim 6, wherein a liquid handling member is substantially geometrically saturated with liquid before the first acquisition of urine into said liquid handling member. 9. An absorbent article designed to carry out a process according to claim 8. 10. An absorbent article according to claim 9, wherein said article is a disposable absorbent article. 11. An absorbent article according to claim 10, wherein said disposable absorbent article is a diaper.
