Abstract

An absorbent article ( 10, 110, 210, 310 ) can include a chassis ( 11 ) including an absorbent body ( 34 ). The chassis ( 11 ) can include a body facing surface ( 19 ). The absorbent article ( 10, 110, 210, 310 ) can also include a waist containment member ( 54, 154, 254 ). The waist containment member ( 54, 154, 254 ) can include a proximal portion ( 76 ) coupled to the body facing surface ( 19 ) of the chassis ( 11 ) and a distal portion ( 78 ) that includes a free edge ( 88 ). The distal portion ( 78 ) can be free to move with respect to the chassis ( 11 ) when the absorbent article ( 10, 110, 210, 310 ) is in a relaxed configuration. The free edge ( 88 ) can be about 50.0 millimeters or less from the rear waist edge ( 24 ) of the absorbent article ( 10, 110, 210, 310 ) when the absorbent article ( 10, 110, 210, 310 ) is in the stretched, laid-flat configuration.

First claim

What is claimed is:

1 . An absorbent article including a front waist region including a front waist edge, a rear waist region including a rear waist edge, 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; and a waist containment member disposed on the body facing surface of the chassis, the waist containment member comprising:
a first longitudinal side edge and a second longitudinal side edge;
a proximal portion coupled to the body facing surface of the chassis;
a distal portion including 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
at least three folds when the absorbent article is in a stretched, laid-flat configuration, each of the at least three folds folding the waist containment member in a direction generally parallel to the lateral axis of the absorbent article.

2 . An absorbent article including a front waist region including a front waist edge, a rear waist region including a rear waist edge, 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; and a waist containment member disposed on the body facing surface of the chassis, the waist containment member comprising: a first longitudinal side edge and a second longitudinal side edge; a proximal portion including a first end edge and a second end edge, the proximal portion being coupled to the body facing surface of the absorbent assembly between the first end edge and the second end edge; and a distal portion including a free edge, the distal portion being free to move with respect to the chassis when the absorbent article is in a relaxed configuration, the second end edge of the proximal portion of the waist containment member defining a transition between the proximal portion and the distal portion, the free edge of the distal portion being closer to the rear waist edge than is the first end edge of the proximal portion of the waist containment member when the absorbent article is in a stretched, laid-flat configuration, wherein a length of the distal portion extending in the longitudinal direction is greater than a length of the proximal portion extending in the longitudinal direction.

3 . An absorbent article including a front waist region including a front waist edge, a rear waist region including a rear waist edge, 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; and a waist containment member disposed on the body facing surface of the chassis and spaced from the rear waist edge, the waist containment member comprising:
a first longitudinal side edge and a second longitudinal side edge;
a proximal portion, the proximal portion being coupled to the body facing surface of the chassis;
a distal portion including a free edge, the distal portion being free to move with respect to the chassis when the absorbent article is in a relaxed configuration, the free edge being about 40.0 millimeters or less from the rear waist edge of the absorbent article when the absorbent article is in a stretched, laid-flat configuration; and
a fold defining a transition between the proximal portion and the distal portion,

wherein a length of the distal portion extending in the longitudinal direction is greater than a length of the proximal portion extending in the longitudinal direction.

4 . The absorbent article of claim 1 , wherein the waist containment member includes at least four folds when the absorbent article is in a stretched, laid-flat configuration, each of the at least four folds folding the waist containment member in a direction generally parallel to the lateral axis of the absorbent article.

5 . The absorbent article of claim 4 , wherein the distal portion of the waist containment member includes the at least four folds.

6 . The absorbent article of claim 1 , wherein the waist containment member further comprises at least one elastic member.

7 . The absorbent article of claim 6 , wherein the distal portion of the waist containment member includes the at least one elastic member.

8 . The absorbent article of claim 2 , wherein the free edge of the distal portion of the waist containment member is about 50.0 millimeters or less from the rear waist edge of the absorbent article when the absorbent article is in the stretched, laid-flat configuration.

9 . The absorbent article of claim 8 , wherein the free edge of the distal portion of the waist containment member is about 40.0 millimeters or less from the rear waist edge of the absorbent article when the absorbent article is in the stretched, laid-flat configuration.

10 . The absorbent article of claim 3 , wherein the free edge of the distal portion of the waist containment member is about 30.0 millimeters or less from the rear waist edge of the absorbent article when the absorbent article is in the stretched, laid-flat configuration.

11 . The absorbent article of claim 1 , wherein the proximal portion includes a first edge and a second edge, the second edge defining a transition between the proximal portion and the distal portion of the waist containment member, and wherein the free edge of the distal portion is closer to the rear waist edge than is the first edge of the proximal portion when the absorbent article is in a stretched, laid-flat configuration.

12 . The absorbent article of claim 2 , wherein the free edge of the distal portion is substantially the same distance from the rear waist edge as is the second edge of the proximal portion of the waist containment member when the absorbent article is in a stretched, laid-flat configuration.

13 . The absorbent article of claim 11 , wherein the free edge of the distal portion is substantially the same distance from the rear waist edge as is the second edge of the proximal portion of the waist containment member when the absorbent article is in a stretched, laid-flat configuration.

14 . The absorbent article of claim 1 , wherein the distal portion includes a laminate section, the laminate section being near the free edge of the distal portion.

15 . The absorbent article of claim 14 , wherein the waist containment member further comprises at least one elastic member, the at least one elastic member being disposed in the laminate section of the distal portion of the waist containment member.

16 . The absorbent article of claim 14 , wherein the waist containment member comprises at least three elastic members, the at least three elastic members being disposed in the laminate section of the distal portion of the waist containment member.

17 . 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.

18 . The absorbent article of claim 17 , 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.

19 . 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 a
