Abstract

An absorbent article has attachment regions having body adhesive. The attachment regions have a protected condition where the body adhesive is fully covered. The attachment regions are adapted to transition from the protected condition to a fixed donning condition where a portion of the body adhesive is exposed and a portion of the body adhesive is covered. The attachment regions are adapted to transition from the fixed donning condition to a fully exposed condition where the body adhesive is fully exposed.

First claim

The invention claimed is:

1. An absorbent article comprising,
a shell and an absorbent component, wherein the shell defines, in a longitudinal direction, an anterior attachment region, an anterior separation zone, an absorbent component region, a posterior separation zone, and a posterior attachment region, wherein the anterior separation zone separates the anterior attachment region from the absorbent component region and wherein the posterior separation zone separates the posterior attachment region from the absorbent component region;
the anterior attachment region comprising an anterior body adhesive and an anterior adhesive-free portion and defining a protected condition wherein a first anterior peel strip overlays a first anterior portion of the anterior body adhesive and a second anterior peel strip overlays a second anterior portion of the anterior body adhesive and the first anterior peel strip overlaps the second anterior peel strip at the anterior adhesive-free portion; the anterior attachment region being adapted to transition from the protected condition to a fixed donning condition; in the fixed donning condition a portion of the anterior body adhesive is exposed by removal of the first anterior peel strip and a portion of the anterior body adhesive is covered by the second anterior peel strip; the anterior attachment region being adapted to transition from the fixed donning condition to a fully exposed condition; in the fully exposed condition the anterior body adhesive is fully exposed by removal of the second anterior peel strip;
the posterior attachment region comprising a posterior body adhesive and a posterior adhesive-free portion and defining a protected condition wherein a first posterior peel strip overlays a first posterior portion of the posterior body adhesive and a second posterior peel strip overlays a second posterior portion of the posterior body adhesive and the first posterior peel strip overlaps the second posterior peel strip at the posterior adhesive-free portion; the posterior attachment region being adapted to transition from the protected condition to a fixed donning condition; in the fixed donning condition a portion of the posterior body adhesive is exposed by removal of the first posterior peel strip and a portion of the posterior body adhesive is covered by the second posterior peel strip; the posterior attachment region being adapted to transition from the fixed donning condition to a fully exposed condition; in the fully exposed condition the posterior body adhesive is fully exposed by removal of the second posterior peel strip; and
at least one of the anterior separation zone and the posterior separation zone being devoid of absorbent material and body adhesive.

2. The absorbent article of claim 1 wherein the shell defines a shell length, the anterior separation zone defines an anterior separation zone length, the posterior separation zone defines a posterior separation zone length, and at least one of the anterior separation zone length or the posterior separation zone length is at least 5% of the shell length.

3. The absorbent article of claim 2 wherein the shell length is 325 to 350 mm, the anterior separation zone length is 5 to 15 mm, and the posterior separation zone length is 20 to 50 mm.

4. The absorbent article of claim 3 wherein the anterior separation zone is elastic, the posterior separation zone is elastic, the anterior attachment region is inelastic, and the posterior attachment region is inelastic.

5. An absorbent article comprising,
a shell and an absorbent component, wherein the shell defines, in a longitudinal direction, an anterior attachment region, an anterior separation zone, an absorbent component region, a posterior separation zone, and a posterior attachment region, wherein the anterior separation zone separates the anterior attachment region from the absorbent component region and wherein the posterior separation zone separates the posterior attachment region from the absorbent component region; wherein the absorbent article defines a body-facing surface and a garment-facing surface;
the anterior attachment region comprising an anterior body adhesive disposed on the body-facing surface and defining a protected condition wherein an anterior peel strip overlays the anterior body adhesive, the anterior peel strip defining a body adhesive facing surface and an opposite surface wherein an anterior anchor is attached to the opposite surface of the anterior peel strip and wherein the anterior attachment region comprises a longitudinal fold wherein a first anterior portion of the opposite surface of the anterior peel strip is attached to a second anterior portion of the opposite surface of the anterior peel strip via the anterior anchor to define the protected condition; the anterior attachment region being adapted to transition from the protected condition to a fixed donning condition; in the fixed donning condition a portion of the anterior body adhesive is exposed and a portion of the anterior body adhesive is covered by the anterior peel strip; the anterior attachment region being adapted to transition from the fixed donning condition to a fully exposed condition; in the fully exposed condition the anterior body adhesive is fully exposed;
the posterior attachment region comprising a posterior body adhesive disposed on the body-facing surface and defining a protected condition wherein a posterior peel strip overlays the posterior body adhesive, the posterior peel strip defining a body adhesive facing surface and an opposite surface, wherein a posterior anchor is attached to the opposite surface of the posterior peel strip and wherein the posterior attachment region comprises a longitudinal fold wherein a first posterior portion of the opposite surface of the posterior peel strip is attached to a second posterior portion of the opposite surface of the posterior peel strip via the posterior anchor to define the protected condition; the posterior attachment region being adapted to transition from the protected condition to a fixed donning condition; in the fixed donning condition a portion of the posterior body adhesive is exposed and a portion of the posterior body adhesive is covered by posterior peel strip; the posterior attachment region being adapted to transition from the fixed donning condition to a fully exposed condition; in the fully exposed condition the posterior body adhesive is fully exposed; and
at least one of the anterior separation zone and the posterior separation zone being devoid of absorbent material and body adhesive.

6. The absorbent article of claim 5 wherein the shell defines a shell length, the anterior separation zone defines an anterior separation zone length, the posterior separation zone defines a posterior separation zone length, and at least one of the anterior separation zone length or the posterior separation zone length is at least 5% of the shell length.

7. The absorbent article of claim 5 wherein the shell length is 325 to 350 mm, the anterior separation zone length is 5 to 15 mm, and the posterior separation zone length is 20 to 50 mm.

8. The absorbent article of claim 5 wherein the anterior separation zone is elastic, the posterior separation zone is elastic, the anterior attachment region is inelastic, and the posterior attachment region is inelastic.

9. An absorbent article comprising,
a shell and an absorbent component, wherein the shell defines, in a longitudinal direction, an anterior attachment region, an anterior separation zone, an absorbent component region, a posterior separation zone, and a posterior attachment region, wherein the anterior separation zone separates the anterior attachment region from the absorbent component region and
