Abstract
The invention relates to absorbent products (1) like baby diapers, adult incontinence products and particularly to sanitary napkins or pantyliners. These absorbent products all have absorbent cores (4) which according to the present invention comprise absorbent gelling materials (5) in granular form or other particles. A problem associated with such cores is that these particles can migrate out of the article along the paths of liquid entry into the product. Therefore, a shield (8) positively separating the paths of liquid transport into the product from the particles is provided for absorbent structures according to the invention.
