Abstract

Absorbent articles of the present disclosure may be constructed with a secondary liner sheet placed on top of a body facing liner of the articles configured to form a pocket. The pocket provides a barrier, thereby separating a front region of the absorbent articles from a rear region. In this manner, the absorbent articles of the present disclosure may reduce the spread of bodily exudates throughout the articles. The reduced spreading of exudates may help to keep skin healthy by reducing the amount of skin exposed to the skin irritants within the exudates and/or by preventing additional skin irritants from being created by preventing the mixing of BM and urine, at least in proximity to the skin of the wearer.

First claim

What is claimed is:

1. An absorbent article comprising:
a chassis extending in a longitudinal direction and having a longitudinal centerline and a lateral direction and having a lateral centerline, the chassis having a front waist region including a front waist edge, a rear waist region including a rear waist edge, and a crotch region extending between the front waist region and the rear waist region, and the chassis comprising:
a garment facing outer cover,
a body facing liner,
an absorbent body disposed between the garment facing outer cover and the body facing liner;
a pair of containment flaps extending between the front waist region and the rear waist region, each of the pair of containment flaps having distal portions and proximal portions; and
a secondary liner sheet having a rear sheet edge, a front sheet edge, and longitudinally extending sheet side edges,
wherein each of the pair of containment flaps are attached to the body facing liner along a first longitudinally extending attachment region disposed proximate the proximal portion,
wherein the secondary liner sheet is attached to each of the pair of containment flaps or attached to the body facing liner along second longitudinally extending attachment regions disposed proximate the longitudinally extending sheet side edge,
wherein each of the pair of containment flaps are attached to the secondary liner sheet proximate the rear sheet edge at a location closer to the longitudinal centerline than the second longitudinally extending attachment regions, and
wherein the second longitudinally extending attachment regions are disposed laterally closer to the longitudinal centerline than the first longitudinally extending attachment regions, and
wherein the secondary liner sheet has a secondary liner sheet width, and wherein the secondary liner sheet width is less than a distance between the first longitudinally extending attachment regions attaching the pair of containment flaps to the body facing liner.

2. He absorbent article of claim 1 , wherein the secondary liner sheet is hydrophilic.

3. The absorbent article of claim 1 , wherein there is no overlap between the first longitudinally extending attachment regions and the second longitudinally extending attachment regions in a vertical direction.

4. The absorbent article of claim 3 , wherein a minimum distance between an edge of the first longitudinally extending attachment regions and an edge of the second longitudinally extending attachment regions is between about 0.5 mm and about 10 mm.

5. The absorbent article of claim 1 , wherein the first longitudinally extending attachment regions form liquid-impermeable barriers between the containment flaps and the body facing liner.

6. The absorbent article of claim 1 , wherein the first attachment regions and the second attachment regions are parallel.

7. The absorbent article of claim 1 , wherein each of the containment flaps comprises an un-folded portion, a fold, and a folded portion, and wherein at least part of the folded portion overlaps the un-folded portion in a vertical direction, the vertical direction being perpendicular to both the longitudinal direction and the lateral direction.

8. The absorbent article of claim 7 , wherein the first longitudinally extending attachment regions vertically overlap both of the folded portions and the un-folded portions of the containment flaps.

9. The absorbent article of claim 8 , further comprising an adhesive disposed between the folded portions and the un-folded portions of the containment flaps.

10. The absorbent article of claim 9 , wherein the first longitudinally extending attachment regions vertically overlap the adhesive disposed between the folded portions and the un-folded portions of the containment flaps.

11. The absorbent article of claim 9 , wherein the second longitudinally extending attachment regions vertically overlap the adhesive disposed between the folded portion and the un-folded portion of the flaps.

12. The absorbent article of claim 1 , wherein the second longitudinally extending attachment regions extend for a longitudinal length between about 50% and about 100% of a longitudinal length of the secondary liner sheet.

13. The absorbent article of claim 1 , wherein the second longitudinally extending attachment regions extend for a longitudinal length between about 75% and about 100% of a longitudinal length of the secondary liner sheet.

14. The absorbent article of claim 1 , wherein each of the second attachment regions forms an angle with respect to the lateral centerline of between about 5 and about 35 degrees.

15. An absorbent article comprising:
a chassis extending in a longitudinal direction and having a longitudinal centerline and a lateral direction and having a lateral centerline and having a depth in a vertical direction, a front waist region including a front waist edge, a rear waist region including a rear waist edge, and a crotch region extending between the front waist region and the rear waist region, and the chassis comprising:
a garment facing outer cover,
a body facing liner,
an absorbent body disposed between the garment facing outer cover and the body facing liner;
a pair of containment flaps extending between the front waist region and the rear waist region, each of the pair of containment flaps comprising a folded portion and an un-folded portion, at least a portion of the folded portion overlapping the un-folded portion in a vertical direction; and
a secondary liner sheet having a rear sheet edge, a front sheet edge, and longitudinally extending sheet side edges,
wherein each of the pair of containment flaps are attached to the body facing liner along longitudinally extending attachment regions,
wherein each of the pair of containment flaps are attached to the secondary liner sheet, with the attachment of the secondary liner sheet to the body facing liner and to the containment flaps configured such that the rear sheet edge of the secondary liner sheet lifts away from the body facing liner along with the proximal edges of the containment flaps when the article is disposed in a relaxed or wear configuration, and
wherein the longitudinally extending attachment regions overlap, in the vertical direction, the folded portion and the un-folded portion of the containment flaps.

16. The absorbent article of claim 15 , wherein the secondary liner sheet is hydrophilic.

17. The absorbent article of claim 15 , wherein each of the pair of containment flaps further comprise a proximal edge and a distal edge, and wherein the pair of containment flaps are attached to the secondary liner sheet proximate the distal edges.

18. The absorbent article of claim 15 , further comprising an adhesive disposed between the folded portion and the un-folded portion of each of the pair of containment flaps.

19. The absorbent article of claim 18 , wherein the longitudinally extending attachment regions overlap, in the vertical direction, the adhesive.
