Abstract
An absorbent article with a longitudinal direction and a transverse direction, a center line (29) running in the longitudinal direction, a center line running in the transverse direction, two side edges (9, 10) running in the longitudinal direction, two end edges (11, 12) running in the transverse direction, and including a liquid-permeable surface layer (2), a liquid-tight surface layer (3), a side barrier pocket (40, 41) arranged along each side edge (9, 10) and having an opening directed towards the longitudinal center line, and an absorption body (4) enclosed between the surface layers (2, 3). The absorption body (4) includes at least one intermediate storage part (22-25) and a liquid transfer part (26). The intermediate storage part (22-25) is arranged along a side edge (9, 10), in direct contact with the liquid transfer part (26), and inside a side barrier pocket (40, 41). The transport of liquid between the material in the intermediate storage part (22-25) and the liquid transfer part (26) is such that the liquid transfer part (26) drains liquid from the intermediate storage part (22-25).
