Abstract

An absorbent article has a top sheet, a back sheet, and an absorbent assembly positioned between the back sheet and the top sheet. The absorbent article includes a fluid intake layer positioned between the absorbent assembly and the top sheet. The fluid intake layer has a rearward-facing arch located in a back portion of the fluid intake layer. The fluid intake layer has an opening. The absorbent article includes a first lateral stiffener and a second lateral stiffener extending along a majority of the longitudinal side edges of the fluid intake layer. The absorbent article includes a first flexure, a second flexure, and a third flexure in a rear portion of the absorbent article.

Claims

1. An absorbent article comprising,

a top sheet,

a back sheet,

an absorbent assembly positioned between the back sheet and the top sheet, and

a fluid intake layer positioned between the absorbent assembly and the top sheet, the fluid intake layer defining a fluid intake layer length in a longitudinal direction and the absorbent article defining an absorbent article length in the longitudinal direction, the fluid intake layer length being 30-60% the absorbent article length, the fluid intake layer also defining an outer perimeter, the outer perimeter having a rearward-facing arch located in a back portion of the fluid intake layer.

2. The absorbent article of claim 1 further comprising,

a first lateral stiffener extending along a first side edge of the fluid intake layer,

a second lateral stiffener extending along a second side edge of the fluid intake layer, and

a first flexure in a rear portion of the absorbent article, the first flexure extending in a direction generally parallel to a longitudinal centerline.

3. The absorbent article of claim 1 further comprising,

a first flexure in a rear portion of the absorbent article, the first flexure extending in a direction generally parallel to a longitudinal centerline,

a second flexure in the rear portion of the absorbent article spaced laterally outward in a first direction from the first flexure, the second flexure defining a first side portion of the absorbent article laterally outward in the first direction from the second flexure and

a third flexure in the rear portion of the absorbent article spaced laterally outward in a second direction from the first flexure, the second direction being opposite the first direction, the third flexure defining a second side portion of the absorbent article laterally outward in the second direction from the third flexure, the second and third flexures defining a central portion of the absorbent article therebetween.

4. The absorbent article of claim 3 further comprising,

a first fastener attached to the garment-facing surface of the back sheet in the first side portion, and

a second fastener attached to the garment-facing surface of the back sheet in the second side portion, wherein

the central portion of the garment-facing surface of the back sheet is substantially free of fasteners.

5. The absorbent article of claim 3 wherein the second flexure and the third flexure diverge rearward relative to the longitudinal centerline and wherein the first flexure, the second flexure, and the third flexure terminate at front points proximate the rearward-facing arch of the fluid intake layer.

6. The absorbent article of claim 3 wherein the first flexure, the second flexure, and the third flexure are embossments in the absorbent assembly.

7. The absorbent article of claim 4 wherein the first fastener is a mechanical hook material attached to the garment-facing surface of the back sheet in the first side portion and the second fastener is a mechanical hook material attached to the garment-facing surface of the back sheet in the second side portion.

8. The absorbent article of claim 4 wherein the first fastener is an adhesive attached to the garment-facing surface of the back sheet in the first side portion and the second fastener is an adhesive attached to the garment-facing surface of the back sheet in the second side portion.

9. The absorbent article of claim 1 wherein the fluid intake layer is an airlaid material comprising bi-component fibers and pulp fibers and the rearward-facing arch defines a length dimension in the longitudinal direction of 7-15 mm.
