Abstract

An absorbent article includes a liquid-permeable sheet, a liquid-impermeable sheet, and an absorber sandwiched between the liquid-permeable sheet and the liquid-impermeable sheet. The absorber includes an absorbing layer center part and an absorbing part formed in the periphery of the absorbing layer center part. On the skin-contact surface side of the absorbent article, compressed grooves are provided along at least widthwise right and left side edges to surround the absorbing layer center part, and have an intermittent portion in the vicinity of the longitudinal centerline. On the skin-non-contact surface side of the absorber, a space part being nearly convex toward the skin-contact surface side and formed between the absorber and the liquid-impermeable sheet, is present in the side part of at least a part of compressed groove out of the compressed grooves provided along widthwise right and left side edges.

Claims

1. An absorbent article comprising at least a liquid-permeable sheet, a liquid-impermeable sheet, and an absorber sandwiched between said liquid-permeable sheet and said liquid-impermeable sheet, wherein:

said absorber consists of an absorbing layer center part and an absorbing part formed in the periphery of said absorbing layer center part to have a lower basis weight compared to said absorbing layer center part;

on the skin-contact surface side of said absorbent article, compressed grooves are provided along at least widthwise right and left side edges to surround said absorbing layer center part, said compressed groove having an intermittent portion in the vicinity of the longitudinal centerline; and

on the skin-non-contact surface side of said absorber, a space part being nearly convex toward the skin-contact surface side and formed between the absorber and the liquid-impermeable sheet, is present in the side part of at least a part of compressed groove out of the compressed grooves provided along widthwise right and left side edges.

2. The absorbent article according to claim 1, wherein said intermittent portion is formed on the longitudinal back side.

3. The absorbent article according to claim 2, wherein said intermittent portion is further formed on the longitudinal front side.

4. The absorbent article according to claim 1, wherein said space part is formed on both side parts of at least a part of compressed groove out of the compressed grooves provided along widthwise right and left side edges.

5. The absorbent article according to claim 1, wherein said space part is formed to extend to both ends of each compressed groove provided along widthwise right and left side edges.
