Abstract

An absorbent article having a front section, a central section and a rear section located along a longitudinal axis is described. A first pattern of adhesive is applied to the central section of a garment facing surface of the backsheet. The first pattern of adhesive has a first plurality of stripes extending substantially parallel to the transverse axis on a first side of the central longitudinal axis. A second plurality of stripes extends substantially parallel to the transverse axis on a second side of the central longitudinal axis. A first gap between the first plurality of stripes and the second plurality of stripes extends over the central longitudinal axis.

First claim

What is claimed is:

1 . An absorbent article having a central longitudinal axis and a transverse axis perpendicular to the longitudinal axis, the absorbent article comprising:
a) a front section, a central section and a rear section located along the longitudinal axis; b) a backsheet having a garment facing surface; c) a first pattern of fastening adhesive applied to the central section of the garment facing surface of the backsheet, the first pattern of adhesive comprising:
i) a first plurality of stripes extending substantially parallel to the transverse axis on a first side of the central longitudinal axis;
ii) a second plurality of stripes extending substantially parallel to the transverse axis on a second side of the central longitudinal axis; and
iii) a first gap between the first plurality of stripes and the second plurality of stripes, wherein the first gap extends over the central longitudinal axis; and
d) a second pattern of fastening adhesive applied to the front section of the garment facing surface of the backsheet, the second pattern of adhesive comprising:
i) a third plurality of stripes extending substantially parallel to the transverse axis on the first side of the central longitudinal axis;
ii) a fourth plurality of stripes extending substantially parallel to the transverse axis on the second side of the central longitudinal axis; and
iii) a second gap between the third plurality of stripes and the fourth plurality of stripes, wherein the gap extends over the central longitudinal axis.

2 . The absorbent article of claim 1 , wherein the first gap has a width substantially parallel to the transverse axis, wherein the width is between about 15 mm and about 35 mm.

3 . The absorbent article of claim 1 , wherein the stripes of the first plurality and the second plurality have a length substantially parallel to the transverse axis, and a width substantially parallel to the longitudinal axis, wherein the length of each stripe is between about 5 mm to about 30 mm and the width is between about 1 mm and about 5 mm.

4 . The absorbent article of claim 1 , wherein the first plurality of stripes further comprises longitudinal gaps between adjacent stripes, wherein the longitudinal gaps are between about 1 mm and about 10 mm.

5 . The absorbent article of claim 1 , wherein each stripe has an outer edge, wherein a distance between the outer edge of stripes in the first pattern and a corresponding outer edge of the absorbent article is between about 10 mm and about 30 mm.

6 . The absorbent article of claim 1 , wherein the stripes of the first and second plurality combined extend across between 10% and 85% of the width of the absorbent article.

7 . The absorbent article of claim 1 , wherein the central section has a total area, wherein an area of the central section covered by adhesive is between 10% and 85% of the total area of the central section.

8 . The absorbent article of claim 1 , wherein stripes of the second pattern of fastening adhesive are longer than stripes of the first pattern of adhesive.

9 . The absorbent article of claim 1 , further comprising a third pattern of adhesive applied to a rear section of the garment facing surface of the backsheet, the third pattern comprising:
i) a fifth plurality of stripes extending substantially parallel to the transverse axis on the first side of the longitudinal axis; ii) a sixth plurality of stripes extending substantially parallel to the transverse axis on the second side of the longitudinal axis; iii) a third gap provided between the fifth plurality of stripes and the sixth plurality of stripes, wherein the third gap extends over the longitudinal axis.

10 . The absorbent article of claim 9 , wherein at least one of the second or third gap is narrower than the first gap.

11 . The absorbent article of claim 10 , wherein the width of the first gap, the second gap, and the third gap are different.

12 . The absorbent article of claim 9 , wherein between 20% and 90% of the front section and the rear section of the absorbent article is covered with adhesive.

13 . The absorbent article of claim 9 , wherein the adhesive pattern is symmetrical about the longitudinal axis.

14 . The absorbent article of claim 1 , wherein a bunch compression force for the absorbent article measured when wet is less than 1.75N.

15 . The absorbent article of claim 1 , wherein a bunch compression force for the absorbent article measured when dry is less than 2.30N.

16 . The absorbent article of claim 1 , wherein the average peel force is less than 2.30N.

17 . An absorbent article having a central longitudinal axis and a transverse axis perpendicular to the longitudinal axis, the absorbent article comprising:
a) a front section, a central section and a rear section located along the longitudinal axis; b) a backsheet having a garment facing surface; c) a first pattern of fastening adhesive applied to the central section of the garment facing surface of the backsheet, the first pattern of adhesive comprising:
i) a first plurality of stripes extending substantially parallel to the transverse axis on a first side of the central longitudinal axis;
ii) a second plurality of stripes extending substantially parallel to the transverse axis on a second side of the longitudinal axis; and
iii) a first gap between the first plurality of stripes and the second plurality of stripes, wherein the first gap extends over the central longitudinal axis; and
d) a second pattern of fastening adhesive applied to the front section of the garment facing surface of the backsheet, the second pattern of adhesive comprising:
i) a third plurality of stripes extending substantially parallel to the transverse axis on the first side of the longitudinal axis; and
ii) a fourth plurality of stripes extending substantially parallel to the transverse axis on the second side of the longitudinal axis, and
iii) a second gap between the third plurality of stripes and the fourth plurality of stripes, wherein the gap extends over the central longitudinal axis;
wherein a distance between an outer edge of the stripes of the second pattern and a corresponding longitudinal edge of the absorbent article is less than a distance between an outer edge of stripes of the first pattern and a corresponding longitudinal edge of the absorbent article.

18 . The absorbent article of claim 17 , wherein the first gap has a width substantially parallel to the transverse axis, wherein the width is between about 15 mm and about 35 mm.

19 . The absorbent article of claim 17 , wherein the adhesive pattern is symmetrical about the longitudinal axis.
