Elasticized disposable training pant and method of making the same
First Claim
1. An elasticized disposable garment comprising:
- (a) a chassis having;
(i) a front portion having an end edge, longitudinal side edges, leg edges, a central region, ear flaps each said ear flap extending laterally outwardly from said central region to said longitudinal side edges and longitudinally along said central region from said end edge to said leg edge;
(ii) a rear portion opposed to said front portion, said rear portion having an end edge, longitudinal side edges, leg edges, a central region, ear flaps each said ear flap extending laterally outwardly from said central region to said longitudinal side edges and longitudinally along said central region from said end edge to said leg edge; and
(iii) a crotch portion between said front portion and said rear portion;
said chassis comprising an outer layer, an elastic waistband member joined to said outer layer in at least said central region of said front portion to form an elasticized waistband, a second elastic waistband member joined to said outer layer in at least said central region of said rear portion to form a second elasticized waistband, and an elastic ear flap member joined to each said ear flap and extending longitudinally from said end edge of said ear flap toward said leg edge of said ear flap to form an elastomeric laminate, each said elastomeric laminate being mechanically stretched to form an elasticized ear flap in each said ear flap of said chassis, each said elasticized ear flap being unitary with said chassis in that said elasticized ear flap comprises a portion of said outer layer and(b) seams joining said front portion to said rear portion adjacent said longitudinal side edges so as to form two leg openings and a waist opening substantially encircled by said end edges.

Abstract
A unitary disposable garment, such as disposable training pants, having a high degree of stretch in the cross-machine direction and fitting a broad range of wearer sizes. The unitary disposable garment is manufactured from a chassis and has a waist opening, two leg openings and a pair of side seams which join the front portion of the chassis to the rear portion of the chassis. The unitary disposable garment preferably has an absorbent assembly, i.e. an absorbent insert, secured to the inner layer of the chassis. The chassis from which the unitary disposable garment is manufactured, has four elasticized ear flaps; each ear flap is elasticized by securing an elastomeric element thereto and mechanically stretching the ear flap and the elastomeric element such that the ear flap is elastically extensible in the direction of initial stretching. The front portion of the chassis is then joined to the rear portion of the chassis on each side of the disposable garment by a seam.
