1. A training pant for use in training a child to use the toilet, comprising:

  • an absorbent chassis defining a longitudinal axis, a transverse axis, an overall length dimension parallel to the longitudinal axis, front and back waist edges parallel to the transverse axis, opposite side edges extending between the front and back waist edges, a front waist region contiguous with the front waist edge, a back waist region contiguous with the back waist edge, and a crotch region which extends between and interconnects the front and back waist regions, the absorbent chassis comprising;

    a composite structure having opposite linear side edges generally parallel to the longitudinal axis and opposite linear end edges generally parallel to the transverse axis, the composite structure comprising;

    (a) a liquid permeable bodyside liner;

    (b) a liquid impermeable outer cover bonded to the bodyside liner, the outer cover comprising a liquid impermeable inner layer and a nonwoven outer layer;

    (c) an outer cover graphic disposed on the outer cover;

    (d) an absorbent assembly comprising hydrophilic fibers disposed between the bodyside liner and the outer cover; and

    (e) leg elastic members longitudinally aligned along the side edges of the composite structure;

    first and second front side panels bonded to the composite structure in the front waist region, each front side panel having a distal edge, an interior portion between the distal edge and the composite structure, a waist end edge generally parallel to the transverse axis and disposed toward a longitudinal end of the training pant, and a leg end edge extending from the respective side edge of the composite structure to the distal edge and disposed toward the longitudinal center of the training pant, the front side panels having an average length dimension that is about 20 percent or greater of the overall length dimension of the absorbent chassis;

    first and second back side panels bonded to the composite structure in the back waist region and longitudinally spaced from the first and second front side panels, each back side panel having a distal edge, an interior portion between the distal edge and the composite structure, a waist end edge generally parallel to the transverse axis and disposed toward a longitudinal end of the training pant, and a leg end edge extending from the respective side edge of the composite structure to the distal edge and disposed toward the longitudinal center of the training pant, the back side panels having an average length dimension that is about 20 percent or greater of the overall length dimension of the absorbent chassis, an elastomeric material disposed between nonwoven facing layers in at least the interior portion of each back side panel to render each back side panel elastomeric in a direction generally parallel to the transverse axis; and

    a fastening system for releasably securing the absorbent chassis in a pant-like configuration having a waist opening and a pair of leg openings, the fastening system comprising first and second fastening components adapted to releasably engage first and second mating fastening components, the first and second fastening components being disposed on the respective first and second back side panels adjacent the distal edges, the first and second mating fastening components being disposed on the respective first and second front side panels adjacent the distal edges, the fastening components and the mating fastening components each comprising mechanical fasteners, and engagement of the fastening components and mating fastening components defines refastenable seams that cover about 80 to 100 percent of a distance between the waist opening and the leg openings.
