Apertured elastic member
An apertured elastic member having a first direction, a second direction perpendicular to the first direction and a substantially constant thickness dimension. The apertures are aligned in a pattern of rows substantially parallel to the first direction. A nonapertured region extends uninterrupted between adjacent rows of apertures parallel to the first direction. The member has a plurality of repeating units, each having substantially the same amount of material everywhere along the repeating unit in a direction parallel to the second direction.
1. An apertured elastic member having a first direction and a second direction perpendicular to said first direction, said apertured elastic member having a plurality of apertures aligned in a pattern of rows substantially parallel to said first direction, and said apertured elastic member having a substantially constant thickness dimension, the apertured elastic member comprising:
a plurality of repeating units, wherein a repeating unit comprises a portion of a first aperture from a first row and a portion of a second aperture from a second row, wherein the second row is adjacent to the first row, and a nonapertured region extending between adjacent rows of apertures, and wherein the nonapertured region of the repeating unit has substantially the same cross sectional area everywhere along the repeating unit in a plane that is parallel to the second direction.
2. The elastic member of claim 1 wherein the amount of material everywhere along the repeating unit, in a direction parallel to the second direction, varies by less than 2%.
3. The elastic member of claim 1 wherein the amount of material everywhere along the repeating unit, in a direction parallel to the second direction, varies by less than 10%.
4. The elastic member of claim 1 wherein said elastic member has an open area ranging from 5% to 80%.
5. The elastic member of claim 1 wherein said elastic member has an open area ranging from 10% to 50%.
6. The elastic member of claim 1 wherein said apertures have a shape selected from the group of circular, triangular, oval, square, hexagonal, octagonal, elliptical, and rectangular.
7. The elastic member of claim 1 wherein said elastic member forms part of a disposable absorbent article.
8. The elastic member of claim 7 wherein said elastic member forms an elastic waist feature in the disposable absorbent article.
9. The elastic member of claim 7 wherein said elastic member forms an elastic side panel in the disposable absorbent article.
10. The elastic member of claim 7 wherein said elastic member forms an elastic leg cuff in the disposable absorbent article.
11. The elastic member of claim 7 wherein said elastic member forms a tape tab in a fastening system in the disposable absorbent article.
12. The elastic member of claim 7 wherein said elastic member forms a topsheet in the disposable absorbent article.
13. The apertured elastic member of claim 1 , wherein said elastic member has a standard variation of the thickness dimension that is less than 15% of the avenge thickness of the elastic member.
14. An apertured elastic member having a first direction and a second direction perpendicular to said first direction, said apertured elastic member having a plurality of apertures aligned in a pattern of rows substantially parallel to said first direction, and said apertured elastic member having a substantially constant thickness dimension, the apertured elastic member comprising:
a plurality of repeating units, wherein a repeating unit comprises a portion of a first aperture front a first row, a portion of a second aperture from a second row, a portion of an aperture adjacent to the first aperture or adjacent to the second aperture, wherein the second row is adjacent to the first row, and a nonapertured region extending between adjacent rows of apertures, and wherein the nonapertured region of the repeating unit has substantially the same cross sectional area everywhere along the repeating unit in a plane that is parallel to the second direction.
15. An apertured elastic member having a first direction and a second direction perpendicular to said first direction, said apertured elastic member having a plurality of apertures aligned in a pattern of rows substantially parallel to said first direction, and said apertured elastic member having a substantially constant thickness dimension, the apertured elastic member comprising:
a plurality of consecutive repeating units, wherein a repeating unit comprises a portion of a first aperture from a first row, a portion of a second aperture from a second row, and a nonapertured region extending between adjacent rows of apertures, wherein the first row is adjacent to the second row, and wherein the nonapertured region of the repeating unit has substantially the same cross sectional area everywhere along the repeating unit in a plane that is parallel to the second direction.
16. The elastic member of claim 15 wherein said elastic member forms an elastic waist feature in the disposable absorbent article.
17. The elastic member of claim 15 wherein said elastic member forms an elastic side panel in the disposable absorbent article.
18. The elastic member of claim 15 wherein said elastic member forms an elastic leg cuff in the disposable absorbent article.
19. The elastic member of claim 15 wherein said elastic member forms a tape tab in a fastening system in the disposable absorbent article.
