Abstract

Reusable cover for an absorbent article providing two or more features selected from maintaining skin condition, fitting a range of wearer shapes and sizes, being easily applied, providing conforming fit, and providing sustained fit.

Claims (64)

1. A reusable outer cover configured to attach to a disposable absorbent insert, wherein the reusable outer cover has a front region, a back region, and a crotch region disposed longitudinally between the front region and the back region, and a wearer-facing surface disposed opposite a garment-facing surface, the reusable outer cover comprising:

an inner layer defining the wearer-facing surface of the outer cover and an outer layer defining the garment-facing surface of the outer cover;

wherein the inner layer is apertured;

an insert attachment point on the inner layer configured to attach to a portion of the disposable absorbent insert;

a first longitudinally extending edge and a second longitudinally extending edge laterally spaced from the first longitudinally extending edge;

a first elastic leg band adjacent the first longitudinally extending edge;

a second elastic leg band adjacent the second longitudinally extending edge;

a first laterally extending edge and a second laterally extending edge longitudinally spaced from the first laterally extending edge;

a first elastic waist band adjacent the first lateral end edge;

a second elastic waist band adjacent the second lateral end edge;

a first side panel having a distal end portion extending laterally outward from the first longitudinally extending edge;

a second side panel having a distal end portion extending laterally outward from the second longitudinally extending edge;

a landing zone in the front region, wherein a portion of the first side panel and a portion of the second side panel are configured to be joined to the landing zone; and

an anchoring band attached to at least one of the inner layer and the outer layer at two or more attachment points between the first and second side panels proximate a laterally extending edge corresponding to the back region of the absorbent article, wherein the anchoring band is free to move relative to the inner and outer layers between the attachment points;

wherein the outer cover has a WVTR of at least 1,200 g/m 2 /24 hr and a Whole Product Back Extension of at least 15% under an applied force of 5N.

2. The outer cover of claim 1 , wherein the outer layer is apertured.

3. The outer cover of claim 1 , wherein the inner layer has a higher modulus of elasticity than the outer layer.

4. The outer cover of claim 1 , wherein the inner layer is hydrophobic.

5. The outer cover of claim 4 , wherein the inner layer and the outer layer are hydrophobic, and wherein the inner layer is more hydrophobic than the outer layer.

6. The outer cover of claim 1 , wherein the outer layer is a woven fabric.

7. The outer cover of claim 1 , wherein the outer layer is made from a material selected from the group consisting of cotton, wool, bamboo, hemp, silk, rayon, polyester, nylon, Lycra, Spandex, breathable waterproof materials with microscopic pores smaller than a water droplet but larger than a water vapor molecule, fabrics comprising microencapsulated phase-change polymer materials, fiber-based moisture wicking systems, and combinations thereof.

8. The outer cover of claim 1 , wherein the outer layer has a basis weight from 0.09-0.15 gram/in 2 .

9. An absorbent article comprising:

the reusable outer cover of claim 1 ; and

a disposable absorbent insert comprising:

a self-contained absorbent assembly comprising:

a fluid impermeable layer; and

a gasketing system.

10. The absorbent article of claim 9 , wherein a portion of a garment-facing surface of the disposable absorbent insert is configured to be attached to the insert attachment point.

11. The outer cover of claim 1 , wherein the outer cover has a WVTR of at least 3000 g/m 2 /24 hr, and wherein the outer cover is launderable.

12. The outer cover of claim 1 , wherein the outer cover has a WVTR of less than 15,000 g/m 2 /24 hr, and wherein the outer cover is laundering resistant.

13. The outer cover of claim 1 , wherein the outer cover has a WVTR of less than 10,000 g/m 2 /24 hr.

14. The outer cover of claim 1 , wherein the outer cover has a Whole Product Back Extension of less than 100 mm under an applied force of 5N.

15. The outer cover of claim 1 , wherein the outer cover has an unload force of at least 1.0N at 25% extension in the Whole Product Back Extension test.

16. The outer cover of claim 1 , wherein the outer cover has an unload force of at least 2.0N at 25% extension in the Whole Product Back Extension test.

17. The outer cover of claim 1 , comprising a second insert attachment point on the inner layer configured to attach to a second portion of the disposable absorbent insert.

18. The outer cover of claim 17 , wherein the insert attachment point is positioned in the front region, and wherein the second insert attachment point is positioned in the back region.

19. A reusable outer cover configured to attach to a disposable absorbent insert, wherein the reusable outer cover has a front region, a back region, and a crotch region disposed longitudinally between the front region and the back region, and a wearer-facing surface disposed opposite a garment-facing surface, the reusable outer cover comprising:

an inner layer defining the wearer-facing surface of the outer cover and an outer layer defining the garment-facing surface of the outer cover;

wherein the inner layer and the outer layer are apertured;
