Abstract

An absorbent core in an absorbent article is provided with at least two folding guides extending in a substantially longitudinal direction in the crotch region and dividing at least a part of the crotch region of the absorbent core in a central portion and two lateral portions as seen in a transverse direction. At least two stretchable crotch elastic members are arranged in the crotch portion of the article and are attached to the absorbent core and/or to the inner or outer cover. At least a substantial portion of the crotch elastic members are positioned laterally outside the respective folding guide so as to cause said two lateral portions of the absorbent core to be raised along said folding guides with respect to the central portion.

Claims

1. An absorbent article comprising:

an absorbent core and a cover enclosing the absorbent core,

said cover comprising a liquid pervious inner cover on the wearer facing side of the absorbent core and a liquid impervious outer cover on the garment facing side of the absorbent core,

said article having a longitudinal and a transverse direction and comprises as seen in its longitudinal direction a front portion, a back portion and a crotch portion there between,

said absorbent core having an elongated shape and comprises a pair of longitudinal edges and a front and a back transverse edge,

said core having a crotch region and at least one outer region as seen in the longitudinal direction of the article,

said outer region or regions being located adjacent the respective transverse edge of the absorbent core,

said absorbent core further being provided with at least two folding guides extending in a substantially longitudinal direction in said crotch region and dividing at least a part of the crotch region of the absorbent core in a central portion and two lateral portions as seen in a transverse direction, said folding guides are grooves or slits extending through at least half the thickness of the absorbent core,

wherein at least two stretchable crotch elastic members are arranged in the crotch portion of the article and are attached to the outer cover and/or to the garment facing side of the absorbent core,

wherein at least a substantial portion of said crotch elastic members are positioned laterally outside the respective folding guide so as to cause said two lateral portions of the absorbent core to be raised along said folding guides with respect to the central portion.

2. The absorbent article as claimed in claim 1, wherein said folding guides have a curved shape.

3. The absorbent article as claimed in claim 1, wherein both ends of said folding guides extend to the adjacent longitudinal edge of the absorbent core.

4. The absorbent article as claimed in claim 1, wherein said folding guides are substantially straight.

5. The absorbent article as claimed in claim 1, wherein one or both ends of said folding guides terminate inside the adjacent longitudinal edge of the absorbent core.

6. The absorbent article as claimed in claim 1, wherein said folding guides are grooves having a lower basis weight than the surrounding areas of the absorbent core.

7. The absorbent article as claimed in claim 1, wherein said folding guides are formed by slits in the absorbent core.

8. The absorbent article as claimed in claim 6, wherein said folding guides are grooves or slits extending through the entire thickness of the absorbent core.

9. The absorbent article as claimed in claim 8, said folding guides are grooves or slits extending through the entire thickness of the absorbent core.

10. The absorbent article as claimed in claim 6, wherein said folding guides are continuous grooves.

11. The absorbent article as claimed in claim 1, wherein said folding guides have length of at least 40 mm.

12. The absorbent article as claimed in claim 1, wherein said crotch elastic members have an active region in longitudinal direction which is at least 40% of the extension in longitudinal direction of the folding guides.

13. The absorbent article as claimed in claim 12, said crotch elastic members have an active region in the longitudinal direction which is at least equal to the entire extension in longitudinal direction of the folding guides.

14. The absorbent article as claimed in claim 1, wherein said crotch elastic members are positioned on, in or laterally outside the lateral portions of the absorbent core over at least 75% of the length of the respective lateral portion in longitudinal direction.

15. The absorbent article as claimed in claim 14, wherein said crotch elastic members are positioned on or in the lateral portions of the absorbent core over at least 40% of the length of the respective lateral portion in longitudinal direction.

16. The absorbent article as claimed in claim 12, wherein said crotch elastic members extend in a straight path.

17. The absorbent article as claimed in claim 1, said crotch elastic members are attached to the outer cover and/or to the garment facing side of the absorbent core.

18. The absorbent article as claimed in claim 1, the article is a diaper, a pant diaper or an incontinence garment.

19. The absorbent article as claimed in claim 6, wherein said folding guides are intermittent grooves.

20. The absorbent article as claimed in claim 1, wherein said folding guides have length of at least 50 mm.

21. The absorbent article as claimed in claim 12, wherein said crotch elastic members have an active region in longitudinal direction which is at least 70% of the extension in longitudinal direction of the folding guides.

22. The absorbent article as claimed in claim 15, wherein said crotch elastic members are positioned on or in the lateral portions of the absorbent core over at least 50% of the length of the respective lateral portion in longitudinal direction.

23. The absorbent article as claimed in claim 12, wherein said crotch elastic members extend in a curved path.
