Disposable pull-on pant
First Claim
1. A unitary disposable pull-on garment comprising:
- (a) a chassis layer comprising a continuous sheet defining(i) a front region having a top end edge, side edges, leg edges, a central panel comprising a waistband panel and a medial panel, side panels extending laterally outwardly from said central panel, and a seam panel extending laterally outwardly from each said side panel to said side edge, said seam panels and said side panels extending longitudinally from said top end edge to said leg edge;
(ii) a back region opposed to said front region, said back region having a top end edge, side edges, leg edges, a central panel comprising a waistband panel and a medial panel, side panels extending laterally outwardly from said central panel, and a seam panel extending laterally outwardly from each said side panel to said side edge, said seam panels and said side panels extending longitudinally from said top end edge to said leg edge; and
(iii) a crotch region between said front region and said back region;
(b) a first belt layer positioned so as to extend continuously laterally across said front region from at least one said side panel to the other said side panel, said first belt layer being joined to said chassis layer, said first belt layer having a top end edge and a bottom edge so as to extend continuously longitudinally along said front region;
(c) a second belt layer positioned so as to extend continuously laterally across said back region from at least one said side panel to the other said side panel, said second belt layer being joined to said chassis layer, said second belt layer having a top end edge and a bottom edge so as to extend continuously longitudinally along said back region;
(d) an elastically extensible front stretch laminate positioned in each said side panel of said front region, each said front stretch laminate comprising a portion of said chassis layer in said side panel, a portion of said first belt layer in said side panel, and an elastic panel member operatively joined with said chassis layer or said first belt layer, each said front stretch laminate being elastically extensible in at least the lateral direction;
(e) an elastically extensible back stretch laminate positioned in each said side panel of said back region, each said back stretch laminate comprising a portion of said chassis layer in said side panel, a portion of said second belt layer in said side panel, and an elastic panel member operatively joined with said chassis layer or said second belt layer, each said back stretch laminate being elastically extensible in at least the lateral direction; and
(f) seams joining said front region to said back region adjacent said side edges in said seam panels so as to form two leg openings and a waist opening.

Abstract
Pull-on garments provided with a continuous belt in the front region and the back region to distribute the forces generated during use in order to better fit the pull-on garment on the wearer. In a preferred embodiment, the pull-on garment comprises a chassis layer comprising a continuous sheet that defines a front region, a back region, and a crotch region; a first belt layer joined to the chassis layer in the front region; a second belt layer joined to the chassis layer in the back region; elastic panel members positioned between the belt layers and the chassis layers which laminate is mechanically stretched to form elastically extensible stretch laminates in both the front region and the back region in the side panels; and seams joining the front region to the back region so as to form the leg openings and waist openings. The continuous chassis layer and belt layers thus form the continuous belt of the pull-on garment. Because the belt layers extend continuously laterally across the waist region and do not cover the entire crotch region, and because the chassis layer is thus exposed in the crotch region, the pull-on garment has a unique aesthetic feature which consumers perceive as providing a cloth-like feel in the waist but the containment characteristics in the crotch.
