Abstract

La présente invention concerne un article absorbant qui est apte, tout en empêchant fermement la fuite latérale d'un liquide excrété, également de rendre une fuite provenant de lui depuis le côté arrière dans le sens longitudinal peu susceptible de se produire. Ledit article absorbant est muni : d'un corps absorbant (2) qui est muni d'un dispositif d'absorption (21); et d'une paire de parties de paroi étanches aux fuites, où chacune des parties de paroi étanches aux fuites présente une base (41), une première paroi (42), une seconde paroi (43), et une partie de commande d'écoulement liquide (Fc) qui est configurée pour comprendre une première articulation (44) et une seconde articulation (45), et le dispositif d'absorption (21) est positionné à l'intérieur du corps absorbant (2) de sorte que, dans une vue en plan, le bord sur le côté de région arrière dans le sens longitudinal est positionné longitudinalement à l'extérieur d'un bord interne (45Ei) positionné le plus loin vers l'intérieur dans le sens longitudinal parmi les bords intérieurs dans le sens de la largeur de la seconde articulation (45), et de sorte que lesdits bords dans le sens de la largeur du dispositif d'absorption (21) sont positionnés à l'extérieur, dans le sens de la largeur, des bords intérieurs dans le sens de la largeur de la base (41) dans au moins une région arrière (AB).
