Abstract
An absorbent article which includes a liquid-permeable outer sheet (1) disposed on a first surface of the article, a liquid-impermeable outer sheet (2) disposed on a second surface of the article, and an absorbent body (3) which is enclosed between the two casing sheets and which includes a receiving space (24) for taking-up body liquid, wherein the space is comprised of at least one cavity or region of lower density than the density of a part of the absorbent body (3) adjacent the receiving space (24) and located generally in the same plane. The article is mainly characterized in that the receiving space (24) is disposed in a storage layer (19) in the absorbent body (3), and in that parts (20,125) of the storage layer (19) adjacent the receiving space (24) include a material which when wetted increases in volume in a direction generally perpendicular to the first surface of the article, whereby the size of the receiving space (24) is also increased in this direction as a result of wetting the article.
