Absorbent core with curved and straight absorbent material areas
First Claim
1. A substantially planar absorbent core comprising a core wrap enclosing an absorbent material, the absorbent core having a longitudinal axis and comprising a front region, a back region and a middle region, each region having an equal length along the longitudinal axis, wherein the absorbent material is substantially free of cellulose fibers and forms a pattern of absorbent material areas, wherein the pattern comprises on each side of the longitudinal axis:
- at least one longitudinally-extending curved area in the middle region of the core, and at least one longitudinally-extending straight area in the front region and/or back region of the core;
wherein the core wrap comprises a first substrate and a second substrate and the first substrate forms substantially the whole of the top side of the core wrap and the second substrate the bottom side of the core wrap, and the first substrate and the second substrate are sealed in a C-wrap configuration along the core wrap'"'"'s longitudinal side edges.

Abstract
A substantially planar absorbent core (28) comprising a core wrap (16, 17) enclosing an absorbent material (60), the absorbent core having a longitudinal axis (80) and comprising a front region (81), a back region (83) and a middle region (82), each region having an equal length (L/3) along the longitudinal axis, wherein the absorbent material is substantially free of cellulose fibers and forms a pattern of absorbent material areas. The pattern comprises on each side of the longitudinal axis at least one longitudinally-extending curved area (601a, 601b) in the middle region of the core, and at least one longitudinally-extending straight area (602a, 602b) in the front region and/or back region of the core.
