Absorbent pad with asymmetrical absorption capacity and absorbent article comprising the same

摘要

The present invention relates to an absorbent pad having a chassis comprising a liquid-permeable topsheet and a liquid-impermeable backsheet, wherein the absorbent pad is geometrically symmetrical along its longitudinal and transversal centre lines. The absorbent pad is provided with attaching arrangements by which the pad can be releasably attached to a separate belt adapted to be placed around the waist of the user. The absorbent pad further comprises an absorbent core interposed between the topsheet and backsheet, which is also geometrically symmetrical along the longitudinal and transversal centre lines of the pad so that the absorbent core is divided into a first longitudinal half and a second longitudinal half along its longitudinal length. The absorbent core has a thickness which is substantially the same on the same distance from the transversal centre line (measured perpendicular to the transversal centre line) before the core is wetted. The first longitudinal half has a higher absorption capacity than the second longitudinal half. The present invention is also directed to an absorbent article comprising the above absorbent pad and a separate belt to which the pad is releasably attached.
