Absorbent article with dual core

1. An absorbent article having a longitudinal centerline, a transverse centerline and a central point where the longitudinal centerline and the transverse centerline cross, comprising;

a liquid permeable topsheet,

a liquid impermeable backsheet joined to the topsheet,

an absorbent core having an area disposed between the topsheet and the backsheet,

wherein the absorbent core comprises a first absorbent core comprising upper surface, a first area and a second area wherein the first area and the second area are horizontally arranged and the second area has a lower absorption capacity than the first area, wherein the second area of the first absorbent core contains superabsorbent polymer in a lower percentage by weight than the first area of the first absorbent core, wherein the second area is surrounded by the first area and wherein the second area is a void extending through the first absorbent core; and

a second absorbent core having a periphery,

wherein the first absorbent core and the second absorbent core are vertically arranged,

wherein the second absorbent core at least partially covers the second area of the first absorbent core, wherein the first absorbent core has a pair of transverse ends opposite from one another, and wherein the second absorben core has a pair of transverse ends opposite form one another, and wherein the transverse ends of the second absorbent core are disposed inboard of the transverse ends of the first absorbent core; and

wherein the first absorbent core and the second absorbent core are different from each other at least in one property selected from the group consisting of their composition, density, absorption capacity, opacity, color, flexibility, or resistance to compression or bunching.

2. The absorbent article of claim 1 , wherein the first absorbent core comprises two density zones.

3. The absorbent article of claim 1 , wherein the first absorbent core comprises superabsorbent polymer.

4. The absorbent article of claim 1 , wherein the second absorbent core comprises an open celled foam.

5. The absorbent article of claim 4 , wherein the open celled foam comprises polyurethane.

6. The absorbent article of claim 1 , wherein the second absorbent core covers more than 20% of the upper surface of the first absorbent core.

7. The absorbent article of claim 1 , wherein the second absorbent core covers more than 30% of the upper surface of the second area of the first absorbent core.

8. The absorbent article of claim 1 , wherein the central point is located within the second absorbent core.

9. The absorbent article of claim 1 , wherein at least part of the first area of the first absorbent core and at least part of the second absorbent core overlap.

10. The absorbent article of claim 1 , wherein the first area of the first absorbent core and the second absorbent core are configured to overlap in the substantially entire periphery of the second absorbent core.

11. The absorbent article of claim 1 , wherein the first area of first absorbent core and the second absorbent core are configured not to overlap with each other.

12. The absorbent article of claim 1 , wherein the first absorbent core has substantially no superabsorbent polymer within 10 mm at least one of outward or inward direction from the periphery of the second absorbent core.

13. The absorbent article of claim 1 , wherein the first absorbent core has a transverse axis and the second absorbent core has a transverse axis, and the transverse axis of the first absorbent core and the transverse axis of the second absorbent core are not consistent each other.

14. The absorbent article of claim 1 , wherein the first absorbent core further comprise a third area a higher absorption capacity than the first area of the first absorbent core.

15. The absorbent article of claim 14 , wherein the third area of the first absorbent core differ from the second absorbent core at least in their composition, density or absorption capacity.
