Abstract

The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.

First claim

What is claimed is:

1 . An absorbent article, comprising:
a chassis comprising a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet; a first belt; a longitudinal centerline extending from the midpoint of a front waist edge of the absorbent article to a midpoint of a back waist edge of the absorbent article; a lateral centerline extending perpendicular to the longitudinal centerline through a midpoint of the longitudinal centerline; wherein the first belt is formed at least in part by an elastomeric laminate comprising a first substrate layer, a second substrate layer and a first plurality of elastics disposed between the first and second substrate layers, wherein the first substrate layer is bonded directly with the second substrate layer in elastic regions of the elastomeric laminate; wherein the first plurality of elastics comprises greater than about 40 elastic strands disposed at an Average-Strand-Spacing of less than 4 mm, having an Average-Dtex of less than 600, and having an Average-Pre-Strain of less than 400%.

2 . The absorbent article of claim 1 , wherein the first plurality of elastics comprises greater than about 100 strands disposed at an Average-Strand-Spacing of less than 3 mm having an Average-Dtex of less than 150 and an Average-Pre-Strain of less than 350%.

3 . The absorbent article of claim 1 , wherein the first plurality of elastics comprises greater than about 100 strands disposed at an Average-Strand-Spacing of less than 2 mm, and having an Average-Dtex of less than 125 and an Average-Pre-Strain of less than 300%.

4 . The absorbent article of claim 1 , wherein the first plurality of elastics comprises greater than about 150 strands disposed at an Average-Strand-Spacing of less than 1.5 mm, and having an Average-Dtex of less than 100 and an Average-Pre-Strain of less than 300%.

5 . The absorbent article of claim 1 , wherein the first plurality of elastics comprises greater than about 200 strands disposed at an Average-Strand-Spacing of less than 1 mm, and having an Average-Dtex of less than 100 and an Average-Pre-Strain of less than 250%.

6 . The absorbent article of claim 1 , wherein the first plurality of elastics comprises greater than about 200 strands disposed at an Average-Strand-Spacing of less than 0.75 mm, and having an Average-Dtex of less than 100 and an Average-Pre-Strain of less than 250%.

7 . The absorbent article of claim 1 , wherein the first plurality of elastics comprise greater than about 250 strands disposed at an Average-Strand-Spacing of less than 0.5 mm, and having an Average-Dtex of less than 100 and an Average-Pre-Strain of less than 250%.
