First Claim
1. An absorbent garment having longitudinal and transverse axes, the garment comprising:
- a three-dimensional pant body defining a waist opening, two leg openings, and a crotch region;
a containment trough having a liquid impermeable base portion bonded to the crotch region and integral retaining walls transversely outward from the base portion, each retaining wall .;
being liquid impermeable and freestanding from the pant body;
elastic members operatively joined to the retaining walls to define freestanding elasticized flaps, each flap comprising on of the liquid impermeable walls and having an inwardly-directed face that is adapted to transport liquid in the plane of the inwardly directed face as defined by a first Wicking Value greater than zero;
an absorbent structure disposed between the flaps, the absorbent structure having upper and lower surfaces, longitudinally spaced end edges, and side edges extending between the end edges; and
a liner bonded to the containment trough and formed of a liquid permeable material that is adapted to transport liquid in the plane of the liquid permeable material as defined by a second Wicking Value, the liner covering the upper surface, wrapped over the side edges, and covering at least part of the lower surface of the absorbent structure;
wherein the second Wicking Value is at least 2 times greater than the first Wicking Value on a gram per gram basis.

Abstract
An absorbent garment includes a three-dimensional pant body defining a waist opening, two leg openings, and a crotch region. A containment trough formed of liquid,impermeable material has a base portion bonded to the crotch region and integral retaining walls positioned transversely outward from the base portion. The retaining walls are freestanding from the pant body and include elastic members so as to define freestanding, elasticized flaps. An absorbent structure and liner are disposed between the elasticized flaps. To retard liquid movement away from the absorbent structure, the liner is wrapped around the side edges and partly beneath the absorbent structure. Further, an inwardly-directed face of each flap has a first Wicking Value while the liner has a second Wicking Value that is at least 2 times greater than the first Wicking Value on a gram per gram basis.
