Abstract

The present disclosure relates to taped and pant articles comprising substantially identical chassis.

First claim

What is claimed is:

1 . Disposable absorbent articles comprising substantially identical chassis, comprising:
a taped article in a first package comprising a first chassis, a front waist region and a back waist region, wherein the back waist region comprises laterally opposed ear flaps joined to side edges of the first chassis, wherein proximal side edges of the ear flaps comprise fasteners, wherein the fasteners are not fastened to form a waist opening, such that the taped article is configured as an open diaper in the first package; a pant article in a second package comprising a second chassis, a front waist region and a back waist region, wherein a front belt flap is joined to the front waist region and a back belt flap is joined to the back waist region, and wherein side edges of the front and back belts are joined to form laterally opposed side seams, thus forming a waist opening and leg openings, such that the pant article is configured as a pre-closed diaper in the second package; wherein the first and second chassis are at least identical to the extent that:
each of the first and second chassis comprise identical chemical compositions of one or more of a topsheet, backsheet film, backsheet nonwoven, core super absorbent polymers, core pulp, core nonwoven, core tissue, leg cuff film, leg cuff nonwoven, super absorbent polymer adhesive, core nonwoven adhesive, leg cuff elastic adhesive, and backsheet nonwoven/film adhesive; and
each of the first and second chassis comprise the same basis weight of one or more of the topsheet, backsheet film, backsheet nonwoven, core super absorbent polymers, core pulp, leg cuff nonwoven, leg cuff film, super absorbent polymer adhesive, leg cuff adhesive, and backsheet nonwoven/film adhesive;
wherein the front belt flap comprises a first end edge and a second end edge and a folded edge that forms a portion of the waist opening of the pant article, and wherein the first end edge of the front belt flap is disposed longitudinally outboard of the second end edge of the front belt flap and longitudinally inboard of the folded edge of the front belt flap; wherein the back belt flap comprises a first end edge and a second end edge and a folded edge that forms a portion of the waist opening of the pant article, and wherein the first end edge of the back belt flap is disposed longitudinally outboard of the second end edge of the back belt flap and longitudinally inboard of the folded edge of the back belt flap; wherein a first portion the first end edge of the front belt flap overlaps the second chassis from a first side edge of the second chassis to a second side edge of the second chassis, and wherein the first portion of the first end edge of the front belt flap is joined to an interior surface of the second chassis, and wherein a second portion of the first end edge of the front belt flap does not overlap the second chassis and is joined to an interior surface of the front belt flap; and wherein the second end edge of the front belt flap overlaps the second chassis from the first side edge of the second chassis to the second side edge of the second chassis and is joined to an exterior surface of the second chassis.
