초록 ▼

A disposable absorbent pant having a belt structure and a longitudinally channeled absorbent core structure is disclosed. The channels include at least one shorter, at least partially transversely-oriented secondary channel in the front and/or rear, to provide a hinge structure in the core, enabling the core to flex laterally and reduce the likelihood of undesirable bulging in the front and/or rear of the pant while it is worn, after the core has absorbed liquid and stiffened longitudinally as a result of the channeled structure.

1. A disposable absorbent pant, having a longitudinal axis, a lateral axis, a front region with a front waist edge, a rear region with a rear waist edge and a crotch region between the front and rear regions, comprising: an absorbent structure comprising an absorbent layer with at least one longitudinally-oriented elongate main channel formed therein, the main channel having a first length and respective frontward and rearward distal ends; andfront and rear elasticized belt structure in each of the front and rear regions, each belt structure having an inner layer, an outer layer and a plurality of laterally-oriented strands of elastomeric material including a lowest strand disposed between the inner layer and the outer layer, a waist edge, and a lower edge formed by one or both of the inner and outer layers, the lower edge being disposed between the waist edge and the lateral axis,wherein the at least one main channel extends from the crotch region into at least one of the front region and the rear region such that at least one of the respective frontward and rearward distal ends of the main channel is disposed above the lowest strand of the front or rear elasticized belt structure. 2. The pant of claim 1 having at least one elongate secondary channel formed in the absorbent layer, the secondary channel having a second length, the second length being shorter than the first length and having a transverse direction component. 3. The pant of claim 2 wherein the secondary channel is disposed above the lower edge of one of the belt structures. 4. The pant of claim 2 wherein the secondary channel is disposed below the lower edge of one of the belt structures. 5. The pant of claim 2 wherein the secondary channel is curved or arcuate and is disposed in the front region. 6. The pant of claim 5 wherein the secondary channel has a curvature that is concave with respect to the front waist edge. 7. The pant of claim 2 in which the at least one secondary channel joins with the at least one main channel. 8. The pant of claim 1 having at least one elongate secondary channel formed in the absorbent layer in each of the front and rear regions, the at least one secondary channel in each region having a second length, the second length being shorter than the first length and having a transverse direction component. 9. The pant of claim 8 in which the secondary channel in each of the front and rear regions is curved or arcuate. 10. The pant of claim 9 wherein the secondary channel in the front region has a curvature that is concave with respect to the front waist edge, and the secondary channel in the rear region has a curvature that is convex with respect to the rear waist edge. 11. The pant of claim 1 wherein the at least one main channel extends from a point in the front region above the lowest strand of the front belt structure, through the crotch region and into the rear region to a point above the lowest strand of the rear belt structure. 12. The pant of claim 1 wherein each of the front and rear belt structures comprises a left zone disposed to the left of a left longitudinal edge of the absorbent structure, a right zone disposed to the right of a right longitudinal edge of the absorbent structure, and a center zone disposed between the left and right zones; and the at least one of the frontward and rearward distal ends of the main channel underlies the center zone of at least one of the front and rear belt structures to a wearer-facing side thereof. 13. The pant of claim 12 wherein the center zone overlying the frontward or rearward distal end of the main channel exhibits less lateral elastic stretch and contraction than the left and right zones. 14. The pant of claim 1 wherein the absorbent layer has at least two longitudinally-oriented elongate main channels formed therein, the main channels having a first length and respective frontward and rearward distal ends. 15. The pant of claim 14 wherein the at least two main channels are curved or arcuate. 16. The pant of claim 1 having left and right side seams at which the elasticized belt structure is affixed to an opposing belt structure, the left and right side seams each having a waist end and a leg opening end; and wherein the at least one of the frontward and rearward distal ends of the at least one main channel is disposed longitudinally above the leg opening end of each seam. 17. The pant of claim 16 wherein at least one of the left and right side seams is refastenable.
