A disposable absorbent article includes two laterally opposing longitudinally extending backsheet strips attached to an exterior surface of an absorbent assembly in laterally opposing attachment zones. Each backsheet strip may include a water-impermeable layer and may be extensible. The absorbent assembly includes laterally opposing side flaps which may be formed by folding portions of the absorbent assembly laterally inward. A longitudinally extending elastic gathering member is attached to each side flap adjacent to its proximal edge. When the article is worn, the elastic gathering members contract and raise the side flaps to form side barriers. The absorbent assembly includes an absorbent core that may contain superabsorbent particles, which may be contained inside pockets. A portion of the absorbent assembly such as the portion that lies between the backsheet strip attachment zones may be extensible and may include a water-impermeable layer.

L'invention porte sur un article absorbant à jeter comportant sur son enveloppe extérieure deux bandes latérales symétriques s'étendant longitudinalement. Chacune des bandes peut comporter une couche imperméable à l'eau et peut être extensible. La partie absorbante présente de chaque côté des volets latéraux symétriques pouvant être formés par des parties pliables de la partie absorbante repliées latéralement vers l'intérieur. Un élément élastique longitudinal de serrage est fixé à chacun des volets latéraux par son bord proximal. Lorsque l'article est en place, les éléments de serrage se contractent et soulèvent les volets latéraux pour former des barrières latérales. La partie absorbante comporte un noyau absorbant pouvant contenir des particules superabsorbantes qui peuvent être placées dans des poches. Une portion de la partie absorbante, par exemple celle qui se trouve entre les zones de fixation des bandes de l'enveloppe extérieure, peut être extensible et comporter une couche imperméable à l'eau.
