Definitions

  • All the storage portions have the same shape and volume,
  • the amount of the superabsorbent polymer particles accommodated in the storage portion located at the rearmost portion in the front-rear direction is greater than the amount of the superabsorbent polymer particles stored in the storage portion located at the frontmost portion in the front-rear direction.
  • the thickness of the accommodation portion positioned at the rearmost portion at the time of maximum expansion is thicker than the thickness of the accommodation portion positioned at the forefront portion at the time of maximum expansion,
  • the absorbent article of the second or third aspect is provided.
  • an outer portion 24x in the width direction WD of the gather sheet 24s forming the three-dimensional gathers 24 is attached over the entire front-rear direction LD, forming a side flap portion SF where the absorber 23 does not exist.
  • These bonded portions are indicated by dotted patterns in FIG. 1 and can be formed by hot-melt adhesive, heat sealing, or ultrasonic sealing.
  • the liquid-impermeable sheet 21 can be extended to the side flap portions SF instead of the exterior sheet 27 to form the outer surface side of the side flap portions SF.
  • a single-layer absorbent body 23 can contain 0.4 to 1.5 times (weight ratio) of superabsorbent polymer particles as short fibers, and a two-layer absorbent body 23 can contain superabsorbent polymer particles.
  • the body 23A can contain 0.5 to 2.0 times (by weight) the superabsorbent polymer particles as the short fibers, and the lower absorbent body 23B can contain 0.2 to 1.0 times (by weight) the short fibers. ) superabsorbent polymer particles.
  • the thickness of the absorber 23 (excluding a region having grooves, which will be described later) is not particularly limited.
  • each accommodating portion 55 can be determined as appropriate, and for example, the dimension 55x in the width direction WD can be about 14 to 38 mm. Also, the dimension 55y in the front-rear direction LD can be about 15 to 200 mm. The area of each accommodation portion 55 can be about 210 to 7600 mm 2 . The interval 55d (minimum interval if changed) between adjacent housing portions in the front-rear direction can be about 5 to 30 mm. As shown in FIG. 15, when a plurality of rows of accommodating portions are provided in the width direction, the interval 55e (minimum interval when changing) between adjacent rows of accommodating portions in the width direction can be about 5 to 30 mm. .
