Abstract

An absorbent article ( 10, 110, 210 ) can include a chassis ( 11 ) and a waist containment member ( 54 ). The waist containment member ( 54 ) can be disposed on the body facing surface ( 19 ) of the chassis ( 11 ). The waist containment member ( 54 ) can include a proximal portion ( 76 ) and a distal portion ( 78 ). The proximal portion ( 76 ) can be coupled to the body facing surface ( 19 ) of the chassis ( 11 ). The distal portion ( 78 ) can include a body facing surface ( 78 a ), a garment facing surface ( 78 b ), and a free edge ( 88 ). In some embodiments, the waist containment member ( 54 ) can further include a compressible member ( 87 ) coupled to the distal portion ( 78 ) of the waist containment member ( 54 ).

First claim

What is claimed is:

1. An absorbent article including a front waist region, a rear waist region, a crotch region, a longitudinal axis and a lateral axis, the absorbent article comprising:
a chassis including an absorbent body, the chassis including a body facing surface;
a waist containment member disposed on the body facing surface of the chassis, the waist containment member comprising:
a proximal portion being coupled to the body facing surface of the chassis;
a distal portion including a body facing surface, a garment facing surface, and a free edge, the distal portion being free to move with respect to the chassis when the absorbent article is in a relaxed configuration; and
a compressible member coupled to the distal portion, the compressible member wrapping at least a portion of the body facing surface of the distal portion and only a portion of the garment facing surface of the distal portion.

2. The absorbent article of claim 1 , wherein a fold separates the distal portion from the proximal portion.

3. The absorbent article of claim 1 , wherein the chassis further comprises a bodyside liner and an outer cover, the absorbent body being disposed between the bodyside liner and the outer cover.

4. The absorbent article of claim 3 , wherein the bodyside liner includes a body facing surface, and wherein the proximal portion of the waist containment member is coupled to the body facing surface of the bodyside liner.

5. The absorbent article of claim 1 , wherein the waist containment member further comprises a first longitudinal side edge and a second longitudinal side edge, the compressible member extending substantially from the first longitudinal side edge to the second longitudinal side edge.

6. The absorbent article of claim 1 , wherein the compressible member is located only in a central lateral region of the waist containment member.

7. The absorbent article of claim 1 , wherein the compressible member includes a thickness near the free edge of the distal portion of the waist containment member, the thickness being at least about four millimeters.

8. The absorbent article of claim 1 , further comprising a rear waist edge in the rear waist region, and wherein the free edge of the distal portion of the waist containment member is between about 30.0 mm and about 50.0 mm from the rear waist edge of the absorbent article when the absorbent article is in a stretched, laid flat configuration.

9. The absorbent article of claim 1 , wherein the waist containment member is in the rear waist region of the absorbent article.

10. The absorbent article of claim 1 , further comprising:
a pair of containment flaps including a first containment flap and a second containment flap, the first containment flap being on a first side of the longitudinal axis and the second containment flap being on a second side of the longitudinal axis, the first and second containment flap each comprising:
a base portion including a proximal end and a distal end; and
a projection portion configured to extend away from the body facing surface of the absorbent assembly in at least the crotch region when the absorbent article is in a relaxed condition, the projection portion being separated from the base potion at the proximal end of the base portion.

11. The absorbent article of claim 10 , wherein the proximal portion of the waist containment member is disposed over the base portion of the first and second containment flaps.

12. The absorbent article of claim 10 , wherein the proximal portion of the waist containment member is disposed under the base portion of the first and second containment flaps.

13. An absorbent article including a front waist region, a rear waist region, a crotch region, a longitudinal axis and a lateral axis, the absorbent article comprising:
a chassis including an absorbent body, the chassis including a body facing surface;
a waist containment member disposed on the body facing surface of the chassis, the waist containment member comprising:
a proximal portion being coupled to the body facing surface of the chassis;
a distal portion including a body facing surface, a garment facing surface, and a free edge, the distal portion being free to move with respect to the chassis when the absorbent article is in a relaxed configuration;
at least one elastic member, the at least one elastic member being disposed in the distal portion of the waist containment member; and
a compressible member coupled to the distal portion, the compressible member longitudinally overlapping the at least one elastic member.

14. The absorbent article of claim 13 , wherein the compressible member is laterally aligned with the at least one elastic member.

15. The absorbent article of claim 14 , wherein the compressible member is bonded to the body facing surface of the distal portion of the waist containment member.

16. The absorbent article of claim 14 , wherein the compressible member is bonded to the garment facing surface of the distal portion of the waist containment member.

17. The absorbent article of claim 14 , wherein the compressible member wraps the free edge of the waist containment member and is bonded to both the body facing surface and the garment facing surface of the distal portion of the waist containment member.

18. An absorbent article including a front waist region, a rear waist region, a crotch region, a longitudinal axis and a lateral axis, the absorbent article comprising:
a chassis including an absorbent body, the chassis including a body facing surface;
a waist containment member disposed on the body facing surface of the chassis in the rear waist region of the absorbent article, the waist containment member comprising:
a proximal portion being coupled to the body facing surface of the chassis;
a distal portion including a body facing surface and a garment facing surface defining a thickness therebetween, the distal portion further including a free edge, a fold separating the distal portion from the proximal portion, the distal portion being free to move with respect to the chassis when the absorbent article is in a relaxed configuration, the thickness of the distal portion near the free edge being at least about four millimeters, the waist containment member comprising a material that is compressible such that the distal portion is configured to fill at least a portion of a gluteal depression of a wearer;
wherein the waist containment member further comprises at least one elastic member, the at least one elastic member being disposed near the free edge of the distal portion of the waist containment member, the elastic member including a thickness of at least about 4.0 mm.
