Abstract

An absorbent article is provided. The absorbent article includes a bodyside liner, an outer cover, and an absorbent core between the liner and the outer cover. The absorbent article further includes a pair of ears extending outward from the opposite sides of the absorbent article, and a fastening system having a primary fastening system and a secondary fastening system. The primary fastening system includes a primary first fastening component disposed on each of the pair of ears and a primary second fastening component disposed on the outer surface of the article. The secondary fastening system includes a secondary second fastening component on each of the pair of ears and a corresponding secondary first fastening component on the outer surface of the article. Each of the secondary first fastening components has a stiffness in the longitudinal direction of the article of less than 185 milligrams according to a Gurley Stiffness Test.

First claim

What is claimed is:

1. An absorbent article having an inner surface, an outer surface, a front waist portion, a back waist portion, a crotch portion extending longitudinally between and connecting the front waist portion and the back waist portion, the absorbent article comprising:
a chassis having longitudinally opposite ends, transversely opposite sides defining respective side edges, a bodyside liner at least in part defining the inner surface of the article, an outer cover at least in part defining the outer surface of the article, and an absorbent core disposed between the liner and the outer cover;
a pair of ears extending transversely outward from the opposite sides of the chassis at the back waist portion thereof; and
a fastening system comprising a primary fastening system and a secondary fastening system, the primary fastening system comprising a primary first fastening component disposed on each of the pair of ears and a primary second fastening component disposed on the outer surface of the article at the front waist portion, the secondary fastening system comprising a secondary second fastening component on each of the pair of ears and a corresponding pair of spaced apart secondary first fastening components on the outer surface of the article at the front waist portion, each of the secondary first fastening components having a transversely inboard-most longitudinal edge that is disposed transversely inward of a transversely inboard-most point of the respective side edges and having a stiffness in the longitudinal direction of the article of less than 185 milligrams according to a Gurley Stiffness Test;
wherein the absorbent article includes a pair of longitudinally extending foldlines disposed in the front waist portion, and wherein the inboard-most longitudinal edge of each of the secondary first fastening components is transversely outward and spaced apart from a respective longitudinally extending foldline at least a distance equal to a predetermined process range.

2. The absorbent article set forth in claim 1 wherein the secondary first fastening component has the stiffness in the longitudinal direction of the article of less than 160 milligrams according to the Gurley Stiffness Test.

3. The absorbent article set forth in claim 1 wherein the secondary first fastening component has an average stiffness in the longitudinal direction of the article of less than 180 milligrams according to the Gurley Stiffness Test based on a sample size of at least 10 samples.

4. The absorbent article set forth in claim 3 wherein the secondary first fastening component has the average stiffness in the longitudinal direction of the article of less than 160 milligrams according to the Gurley Stiffness Test based on the sample size of at least 10 samples.

5. The absorbent article set forth in claim 4 wherein the secondary first fastening component has the average stiffness in the longitudinal direction of the article of less than 140 milligrams according to the Gurley Stiffness Test based on the sample size of at least 10 samples.

6. The absorbent article set forth in claim 1 wherein the secondary first fastening component is disposed transversely adjacent to the primary second fastening component.

7. The absorbent article set forth in claim 1 wherein the secondary first fastening component is disposed on the primary second fastening component.

8. The absorbent article set forth in claim 1 wherein the primary first fastening component comprises a hook fastener and the primary second fastening component comprises a loop fastener.

9. The absorbent article set forth in claim 1 wherein the chassis has a width at the front waist portion of the article and the absorbent core has a width at the front waist portion of the article that is less than the width of the chassis at said front waist portion of the article, the secondary first fastening component being disposed on the outer surface of the article at the front waist portion thereof transversely between an inboard-most portion of the absorbent core and a respective side of the chassis at the front waist portion of the article.

10. The absorbent article set forth in claim 1 wherein the secondary second fastening components each comprise a loop fastener and the secondary first fastening components each comprise a hook fastener.

11. An absorbent article having an inner surface, an outer surface, a first waist portion, a second waist portion, a crotch portion extending longitudinally between and connecting the first waist portion and the second waist portion, the absorbent article comprising:
a chassis having longitudinally opposite ends, transversely opposite sides defining respective side edges, a bodyside liner at least in part defining the inner surface of the article, an outer cover at least in part defining the outer surface of the article, and an absorbent core disposed between the liner and the outer cover;
a pair of ears extending transversely outward from the opposite sides of the chassis at the second waist portion thereof; and
a fastening system comprising a primary fastening system and a secondary fastening system, the primary fastening system comprising a primary first fastening component disposed on each of the pair of ears and a primary second fastening component disposed on the outer surface of the article at the first waist portion, the secondary fastening system comprising a secondary second fastening component on each of the pair of ears and a corresponding pair of spaced apart secondary first fastening components on the outer surface of the article at the first waist portion, each of the secondary first fastening components having a transversely inboard-most longitudinal edge that is disposed transversely inward of a transversely inboard-most point of the respective side edges and having a peak load corresponding to an edge stiffness in the longitudinal direction of the article of less than 100 grams-force according to an Edge Stiffness Test;
wherein the absorbent article includes a pair of longitudinally extending foldlines disposed in the first waist portion, and wherein the inboard-most longitudinal edge of each of the secondary first fastening components is transversely outward and spaced apart from a respective longitudinally extending foldline at least a distance equal to a predetermined process range.

12. The absorbent article set forth in claim 11 wherein the secondary first fastening component has the peak load corresponding to the edge stiffness in the longitudinal direction of the article of less than 80 grams-force according to the Edge Stiffness Test.

13. The absorbent article set forth in claim 11 wherein the secondary first fastening component has an average peak load corresponding to the edge stiffness in the longitudinal direction of the article of less than 90 grams-force according to the Edge Stiffness Test based on a sample size of at least 5 samples.

14. The absorbent article set forth in claim 13 wherein the secondary first fastening component has the average peak load corresponding to the edge stiffness in the longitudinal direction of the article of less than 80 grams-force according to the Edge Stiffness Test based on the sample size of at least 5 samples.

15. The absorbent article set forth in claim 14 wherein the secondary first fastening component has the average peak load corresponding to the edge stiffness in the longitudinal direction of the article of less than 60 grams-force according to the Edge Stiffness Test based on the sample size of at least 5 samples.

16. The absorbent article set forth in claim
