Une région d'entrejambe (6) d'une couche de type culotte, jetable (1) a une section d'absorption de liquides corporels (45) formée par le montage d'un matériau central absorbant les liquides corporels (4) entre une feuille de surface interne perméable aux liquides (2) et une feuille de surface externe imperméable aux liquides (3). La couche de type culotte, jetable (1) a également une section de réception de déchets corporels (31) formée par la feuille de surface interne (2) et un élément de feuille le plus à l'intérieur (120) qui est disposé entre la feuille de surface interne (2) et la peau du porteur. La section de réception de déchets corporels (31) a une ouverture avant (33) et une ouverture arrière (34). L'élément de feuille le plus à l'intérieur (120) a une partie (33c) formant un bord périphérique (33b) de l'ouverture avant (33) et a également une partie (34c) formant un bord périphérique (34b) de l'ouverture arrière (34). Les parties (33c, 34c) sont opposées l'une à l'autre dans la direction avant-arrière (A) et sont reliées pour former un espace (50) avec une paire d'espaceurs (71), qui sont espacés l'un de l'autre dans la direction latérale (B), montés entre les parties (33c, 34c). L'élément de feuille le plus à l'intérieur (120) a également un séparateur (20a) formé par l'extension d'une partie (36), qui s'étend entre les parties (33c, 34c), en aval vers la partie la plus inférieure (6a) de la région d'entrejambe (6).
