Absorbent article having increased front portion stiffness
First Claim
1. An absorbent article such as a sanitary napkin, an incontinence guard or a panty-liner, which article has a generally elongate shape with a longitudinal direction and a transverse direction, said article comprising:
- two long sides, two short sides, two end portions, said end portions including a front portion and a rear portion, and a central portion located between the end portions and exhibiting a transversely extending cross-sectional line from which a width of the article increases in a direction towards at least one of said short sides of the article, wherein the end portion located at said at least one of said short sides exhibits a maximum width which is larger than a width of the central portion at the cross-sectional line, wherein the long sides of the article change inclination at the cross-sectional line, the inclination being defined by an angle α
between each long side of the article and a longitudinal line parallel to the longitudinal direction of the article, and wherein the width of the central portion has an upper limit of 60 mm, the angle a is 30-90°
, and the article has a stiffness, at least in said front portion, which exceeds 100 N measured according to ASTM D 4032-82.

Abstract
The invention relates to an absorbent article such as a sanitary napkin, an incontinence guard or a panty-liner, which article has a generally elongated shape with a longitudinal direction and a transverse direction and exhibits two long sides, two short sides, two end portions and a central portion, located between the end portions, and exhibiting a transversely extending cross-sectional line from which the width of the article increases in a direction towards a short side of the article, whereby the end portion located at the short side exhibits a maximum width which is larger than the width of the central portion, whereby the article changes inclination at the cross-sectional line, whereby the inclination is defined by an angle between the long side of the article and a longitudinal line parallel to the longitudinal direction of the article, which article exhibits a width of the central portion which has an upper limit of 60 mm, and an angle of 30-90°, and the article has a stiffness, at least in the front portion, which exceeds 100 N measured according to ASTM D 4032-82.
