Abstract

An absorbent article with high fitting property and high absorptivity, where the end part is less deformed, is provided.

An absorbent article comprising at least a liquid-permeable sheet, a liquid-impermeable sheet, and an absorber sandwiched between the liquid-permeable sheet and the liquid-impermeable sheet, wherein the absorber comprises a first absorbing part and a second absorbing part formed nearly on the center part of the first absorbing part and smaller in the area than the first absorbing part, and a compressed groove is continuously provided in nearly closed form to extend from the peripheral edge region in the longitudinal direction of the second absorbing part to the first absorbing part.

Claims

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

wherein the absorber comprises a first absorbing part, and a second absorbing part formed on a center part of the first absorbing part and the second absorbing part having a surface area that is smaller than a surface area of the first absorbing part, and

a compressed groove that extends nearly through the first and second absorbing parts is continuously provided and extends from a peripheral edge region in a longitudinal direction of the second absorbing part to the first absorbing part.

2. The absorbent article according to claim 1, wherein a depth of said compressed groove continuously provided in the peripheral edge region in the longitudinal direction of the second absorbing part is a depth sufficient to penetrate the second absorbing part and reach the first absorbing part.

3. The absorbent article according to claim 1, wherein said absorber has an intermittent portion excluded from formation of the compressed groove, in a peripheral end part in the longitudinal direction of the second absorbing part.

4. The absorbent article according to claim 1, wherein said absorber has an intermittent portion excluded from formation of the compress groove, in a peripheral end part in the longitudinal direction of the first absorbing part.

5. The absorbent article according to claim 1, which is housed in a package in a state of being folded in three portions about laterally extending fold lines that do not intersect the compressed groove.

7. The absorbent article according to claim 2, wherein said absorber has an intermittent portion excluded from formation of the compressed groove, in a peripheral end part in the longitudinal direction of the second absorbing part.

8. The absorbent article according to claim 2, wherein said absorber has an intermittent portion excluded from formation of the compress groove, in a peripheral end part in the longitudinal direction of the first absorbing part.

9. The absorbent article according to claim 2, which is housed in a package in a state of being folded in three portions about laterally extending fold lines that do not intersect the compressed groove.

10. The absorbent article according to claim 3, which is housed in a package in a state of being folded in three portions about laterally extending fold lines that do not intersect the compressed groove.

11. The absorbent article according to claim 5, which is housed in a package in a state of being folded in three portions about laterally extending fold lines that do not intersect the compressed groove.

12. The absorbent article according to claim 7, which is housed in a package in a state of being folded in three portions about laterally extending fold lines that do not intersect the compressed groove.

13. The absorbent article according to claim 8, which is housed in a package in a state of being folded in three portions about laterally extending fold lines that do not intersect the compressed groove.

6. A production method of making an absorbent article, comprising stacking an absorber comprising a first absorbing part and a second absorbing part formed on a center part of the first absorbing part and the second absorbing part having a surface area that is smaller than a surface area of the first absorbing part, a mount and a liquid-permeable sheet in this order on the mount, and continuously applying embossing from the liquid-permeable sheet side over a region from a peripheral edge region in the longitudinal direction of the second absorbing part to the first absorbing part, thereby providing a compressed groove extending from the second absorbing part to the first absorbing part.
