Abstract:
A unitary disposable pull-on garment comprising:(a) a chassis defining(i) a front region having an end edge, side edges, leg edges, 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 end edge to said leg edge;(ii) a back region opposed to said front region, said back region having an end edge, side edges, leg edges, a central panel comprising a waistband panel and medial panel, side panels extending laterally outwardly from said central panel to said side edge, 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 end edge to said leg edge; and(iii) a crotch region between said front region and said back region;said chassis having an outer surface and an inner surface;(b) a backsheet having an outer surface and an inner surface opposite said outer surface;(c) an absorbent core positioned on said inner surface of said backsheet, said absorbent core having a garment-facing surface and a wearer-facing surface;(d) a liquid pervious topsheet positioned on said wearer-facing surface of said absorbent core;(e) an elastically extensible front stretch laminate positioned in, each said side panel of said front region, each said front stretch laminate being elastically extensible in at least the lateral direction;(f) an elastically extensible-back stretch laminate positioned in each said side panel of said back region, each said back stretch laminate being elastically extensible in at least the lateral direction;each said back stretch laminate and said front stretch laminate having:(i) an initial pull extension force between about 150 grams/in to about 225 grams/in at 100% extension when subjected to an initial extension at a rate. of 50.8 cm/min at about 23.degree. C.; and(ii) a second cycle recovery force between about 25 grams/in and about 200 grams/in at 20% to 140% extension when subjected to two extension/recovery cycles at an initial extension at a rate of 50.8 cm/min at about 23.degree. C., held for 30 seconds at 200% extension, relaxed at the same rate, remain unconstrained for one minute, and then repeating at the same rate and conditions; and(g) seams joining said front region to said back region adjacent said side edges in said seam panel so as to form two leg openings and a waist opening.
