Abstract

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

First claim

What is claimed is:

1. Disposable absorbent articles constructed using transformations that are at least 70% the same, 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; and wherein the fasteners extend laterally across the laterally opposed ear flaps;
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 permanent 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 laterally opposed permanent side seams do not comprise fasteners;
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; and
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.

2. The disposable absorbent articles of claim 1 , wherein the ear flaps comprise an elastomeric film.

3. The disposable absorbent articles of claim 1 , wherein the front and back belt flaps comprise a plurality of elastomeric strands disposed transverse to a longitudinal axis of the pant article.

4. The disposable absorbent articles of claim 3 , wherein the front and back belt flaps of the pant article comprise elastomeric film.

5. The disposable absorbent articles of claim 1 , wherein the first and second chassis are at least identical to the extent that the first and second chassis have at least one identical component cross sectional order and disposition of a topsheet, backsheet, core, including the core wrap, in at least one the front waist region, back waist region, and crotch region.

6. The disposable absorbent articles of claim 1 , wherein the first package comprises indication of a first size, and wherein said second package comprises indication of a second size, wherein said first and second sizes are different.

7. The disposable absorbent articles of claim 6 , wherein the first package comprises size X articles and the second package comprises size X+1 articles.

8. The disposable absorbent articles of claim 1 , wherein the first package comprises size X articles and the second package comprises size X−1 articles.

9. The disposable absorbent articles of claim 1 , wherein each of the first and second chassis comprise absorbent gelling material, and wherein the absorbent gelling material of each are compositionally identical.

10. The disposable absorbent articles of claim 9 , wherein the absorbent gelling material of each chassis is adhered to each chassis with compositionally identical adhesive.

11. The disposable absorbent articles of claim 1 , wherein the first and second chassis are at least identical to the extent that the first and second chassis have identical component cross disposition of a topsheet, backsheet, core, including the core wrap, in the crotch region.

12. The disposable absorbent articles of claim 1 , wherein the first and second chassis are at least identical to the extent that the first and second chassis have identical component cross sectional order and disposition of a topsheet, backsheet, core, including the core wrap, in the front waist region and the back waist region.

13. The disposable absorbent articles of claim 1 , wherein the average chassis width of the articles of the first package is substantially the same as the average chassis width of the articles of the second package.

14. The disposable absorbent articles of claim 1 ,
wherein a first portion the first end edge of the back 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 wherein the first portion of the first end edge of the back belt flap is joined to the interior surface of the second chassis, and wherein a second portion of the first end edge of the back belt flap does not overlap the second chassis and is joined to an interior surface of the back belt flap; and
wherein the second end edge of the back 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.

15. The disposable absorbent articles of claim 14 , wherein the back belt flap has a greater longitudinal distance at or adjacent to a side seam formed between the front and back belt flap than the longitudinal distance at or adjacent to the side seam of the front belt flap.

16. The disposable absorbent articles of claim 1 , wherein the first chassis comprises a waistband disposed inboard of side edges the first chassis, wherein the waistband is discrete from the first chassis.

17. The disposable absorbent articles of claim 1 , wherein the backsheets of the first and second articles are substantially the same width.

18. The disposable absorbent articles of claim 1 , wherein core wraps of the first and second articles are in the same configuration.

19. The disposable absorbent articles of claim 1 , wherein the backsheets of the ta
