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.

La présente invention concerne des produits absorbants (1) tels que des couches pour bébés ou pour adultes incontinents, et en particulier des serviettes hygiéniques ou des protège-slips. Ces produits absorbants comprennent tous un coeur absorbant (4) qui, selon la présente invention, comporte un matériau gélifiant absorbant (5) sous forme granulaire ou d'autres particules. Un problème lié à l'utilisation de tels coeurs est que les particules qu'il contient peuvent sortir de l'article en suivant les passages permettant aux liquides d'entrer dans le produit. Pour cette raison, un écran (8), qui sépare de façon sûre les passages permettant le transport de liquide dans le produit desdites particules, est placé dans une structure absorbante selon l'invention.
