Abstract

A formed web comprising discrete three-dimensional elements formed therein, wherein at least some of the discrete three-dimensional elements comprise chads with corresponding apertures, wherein the aperture has a perimeter, wherein the chad has a length, wherein the chads are attached along a portion of the aperture perimeter which forms a connection segment, wherein the connection segment is less than about 50% of the entire aperture perimeter, and wherein the web comprises a film.

First claim

What is claimed is:

1. An absorbent article comprising a body contacting-surface and a non-body contacting-surface, and a formed web comprising discrete three-dimensional elements formed therein, wherein at least some of the discrete three-dimensional elements comprise chads with corresponding apertures, wherein each corresponding aperture comprises two or less chads, wherein the discrete three-dimensional elements comprising chads form a portion of the body contacting-surface and at least a portion of each of the chads extends away from the non-body contacting-surface, and wherein each of the chads is attached along a portion of an aperture perimeter of the corresponding apertures, each of which forms a connection segment, wherein each connection segment is less than about 40% of the entire aperture perimeter, and wherein the formed web comprises a film, and wherein the formed web comprises land area surrounding the discrete three-dimensional elements comprising chads, and wherein each of the chads comprises at least a portion which is thinned at least about 25% relative to the thickness of the surrounding land area, wherein each of the chads comprises a length measured from the connection segment to a distal end which is greater than the diameter of the corresponding apertures, and wherein the formed web has a thickness between 5 and 150 microns.

2. The absorbent article of claim 1 , wherein each of the chads are hingeable about the connection segment.

3. The absorbent article of claim 1 , wherein the length is at least about 30 microns.

4. The absorbent article of claim 1 , wherein the length is at least about 300 microns.

5. The absorbent article of claim 1 , wherein each of the chads are bendable at various points along their length.

6. The absorbent article of claim 1 , wherein the formed web comprises at least a second web in addition to the formed web, wherein an embossed seal joins at least a portion of the at least two webs, the seal including co-registered concentric discrete three-dimensional elements formed in the at least two webs, the discrete three-dimensional elements having open proximal ends.

7. The absorbent article of claim 1 , wherein the three-dimensional elements comprising chads comprise a center-to-center spacing between adjacent three-dimensional elements comprising chads of about 100 microns to about 800 microns.

8. The absorbent article of claim 1 , wherein the area density of the web is between about 0.1 to about 10,000 three-dimensional elements comprising chads per square centimeter.

9. The absorbent article of claim 1 , wherein some but not all of the discrete three-dimensional elements comprise chads and corresponding apertures.

10. The absorbent article of claim 1 , wherein the formed web comprises at least a second type of discrete three-dimensional elements.

11. The absorbent article of claim 10 , wherein the formed web comprises at least a third type of discrete three-dimensional elements.

12. The absorbent article of claim 1 , wherein each of the discrete three-dimensional elements comprising chads has only one chad per corresponding aperture.

13. An absorbent article comprising a body contacting-surface and a non-body contacting-surface, and a formed web, the formed web comprising generally planar first and second surfaces, the second surface being opposite the first surface, the formed web further comprising discrete three-dimensional elements extending from the first surface, wherein at least some of the discrete three-dimensional elements comprise chads with corresponding apertures, wherein each corresponding aperture comprises two or less chads, wherein the discrete three-dimensional elements comprising chads form a portion of the body contacting-surface and at least a portion of each of the chads extends away from the non-body contacting-surface, and wherein each of the chads is attached along a portion of an aperture perimeter of the corresponding apertures, each of which forms a connection segment, wherein each connection segment is less than about 40% of the entire aperture perimeter, wherein each of the chads is hingeable about the connection segment, wherein the formed web comprises a film, and wherein the formed web comprises land area surrounding the discrete three-dimensional elements comprising chads, and wherein each of the chads comprises at least a portion which is thinned at least about 25% relative to the thickness of the surrounding land area, wherein each of the chads comprises a length measured from the connection segment to a distal end which is greater than the diameter of the corresponding apertures, and wherein the formed web has a thickness between 5 and 150 microns.

14. The absorbent article of claim 13 , wherein the absorbent article is a feminine hygiene article, adult incontinence article, or diaper.

15. The absorbent article of claim 13 , wherein some but not all of the discrete three-dimensional elements comprise chads and corresponding apertures.

16. The absorbent article of claim 13 , wherein the formed web comprises at least a second type of discrete three-dimensional elements.

17. The absorbent article of claim 16 , wherein the formed web comprises at least a third type of discrete three-dimensional elements.

18. The absorbent article of claim 13 , wherein the discrete three-dimensional elements comprising chads with corresponding apertures have only one chad per aperture.

19. An absorbent article comprising a formed web, wherein the web comprises a first surface and a second surface, wherein the first surface is a body contacting-surface and the second surface is a non-body contacting-surface, wherein the formed web comprises a plurality of chads with corresponding apertures, wherein each corresponding aperture comprises two or less chads, wherein each of the plurality of chads forms a portion of the body contacting-surface and at least a portion of each of the plurality of chads extends away from the non-body contacting-surface, and wherein each of the plurality of chads is attached along a portion of an aperture perimeter of the corresponding apertures, each of which forms a connection segment, wherein each connection segment is less than about 40% of the entire aperture perimeter, wherein the web additionally comprises at least second discrete three-dimensional elements, wherein the second discrete three-dimensional elements extend away from the body contacting surface, wherein the web additionally comprises at least third discrete three-dimensional elements, wherein the third discrete three-dimensional elements extend away from the body contacting surface, wherein the chads, second, and third discrete three-dimensional elements are different from each other in size and shape, and wherein the formed web comprises land areas surrounding the chads, wherein each of the plurality of chads comprises at least a portion which is thinned at least about 25% relative to the thickness of the surrounding land area, wherein each of the chads comprises a length measured from the connection segment to a distal end which is greater than the diameter of the corresponding apertures, and wherein the formed web has a thickness between 5 and 150 microns.

20. The absorbent article of claim 19 , wherein the first, second, and third discrete three-dimensional elements are located in three different regions of the absorbent article.

21. The absorbent article of claim 19 , wherein each corresponding aperture with chads comprises only one chad per aperture.
