  • the pair of folded flap portions 80 inclines obliquely to the width direction W. Due to the distortion due to the expansion and contraction, the gap I is more easily formed below the flap portion 80. Therefore, the assistant or user can easily insert a finger by the gap I under the folded flap portion 80, and the flap portion can be more easily deployed.
  • the waist expansion and contraction portion 85 extend outward in the width direction W beyond the outer edge of the absorber 40.
  • the action of the waist stretchable portion 85 pulling the flap portion 80 is increased, and the pair of folded flap portions 80 can be more easily inclined at an angle with respect to the width direction W.
  • the gap I is more easily formed on the lower side of the flap portion 80. Therefore, the assistant or user can easily insert a finger by the gap I under the folded flap portion 80, and the flap portion can be more easily deployed.
  • the waist stretch unit 85 extends outward in the width direction W beyond the longitudinal fold line FL3. Since the folded flap portion 80 is also pulled to the outside in the width direction W, the flap portion 80 is more easily inclined, and the gap I is easily generated below the flap portion 80. Therefore, the assistant or the user can easily insert a finger by the gap I under the folded flap portion 80, and the flap portion 80 can be more easily deployed.
  • the leg side gathers 71 extend along the longitudinal direction L at least in the crotch region S2, and a part of the effective stretch area of the leg side gathers 71 reaches the flap portion 80.
  • the effective stretch area of the leg side gathers 71 is defined by the area of the elastic member joined to the sheet in the stretched state. Since the vicinity of the root of the folded flap portion 80 is dragged by the leg side gathers 71, a gap I is likely to be generated in the region near the longitudinal fold line FL3 of the folded flap portion 80. Therefore, the assistant or the user can easily insert the finger by the gap I, and the flap 80 can be more easily deployed.

Abstract

L'invention concerne un article absorbant de type bande qui présente une structure facilement extensible. L'article absorbant comprend : une direction longitudinale (L) ; une direction de la largeur (W) orthogonale à la direction longitudinale ; une zone de taille avant (S3) ; une zone de taille arrière (S1) ; une zone d'entrejambe (S2) entre la zone de taille avant et la zone de taille arrière ; un absorbeur (40) disposé au moins dans la zone d'entrejambe ; une paire de parties de rabat (80) qui s'étendent, dans la zone de taille arrière, vers l'extérieur au-delà de l'absorbeur dans la direction de la largeur ; et des bandes de fixation (90) qui sont disposées sur la paire de parties de rabat et qui comportent des crochets qui viennent en prise avec la zone de taille avant. Les bandes de fixation comprennent des parties pliables extensibles qui sont pliées en au moins trois couches. Dans un état dans lequel l'article absorbant est plié, les parties de rabat sont pliées à partir de lignes de pliage longitudinales (FL3) le long de la direction longitudinale. Dans un état dans lequel la paire de parties de rabat sont pliées à partir des lignes de pliage longitudinales, les bandes de fixation disposées sur la paire de parties de rabat se chevauchent mutuellement.
