Abstract

An absorbent article having a longitudinal centerline, a front region, a crotch region, and a back region. The absorbent article has a main portion, a side portion, and a waist portion. The waist portion has a belt portion that has a front belt portion having elastomeric material and a back belt portion having elastomeric material. The front belt portion has a first elastic section and a second elastic section, each section having force zones. The back belt portion has a third elastic section and a fourth elastic section, each section having force zones. The force zones in the portions alternate between a high force zone and a low force zone in at least one belt portion.

First claim

What is claimed is:

1. An absorbent article having a longitudinal centerline, a transverse centerline, a front region, a crotch region, and a back region,
the absorbent article comprising a main chassis portion comprising an absorbent main body, and a waist portion; the waist portion comprising a belt portion; the belt portion comprising a front belt portion and a back belt portion; the absorbent main body comprising an absorbent core;
wherein the front belt and the back belt portions are joined at side edges to form a first seam comprising a first end and a second end and a second seam comprising a first end and a second end;
wherein the first ends of the first and second seams are disposed immediately adjacent to a waist opening, and wherein the second ends of the first and second seams are disposed immediately adjacent to a first leg opening and a second leg opening;
wherein a transverse seam axis intersects each of the second ends of the first and second seams, and runs substantially parallel to the transverse centerline;
wherein the front belt portion comprises a first elastic section comprising a first plurality of elastics exhibiting a first force profile and a second elastic section comprising a second plurality of elastics exhibiting a second force profile;
wherein a surface of the front belt portion and a surface of the back belt portion is formed from a first belt layer extending from a first waist edge in a first waist region through the crotch region to a longitudinally opposing second waist edge in a second waist region and forms at least a portion of an outer surface of the absorbent article;
wherein the surface extending from a first waist edge to a longitudinally opposing second waist edge folds at the front waist edge forming a portion of the of an inner surface of the front waist belt;
wherein the distance between the absorbent main body and the back waist edge is greater than the distance between the absorbent main body and the back waist edge;
wherein the back belt comprises a third plurality of elastics;
wherein the at least a portion of the third plurality of elastics of the back belt overlap the at least a portion of the absorbent core;
wherein each of the first plurality of elastics in the first elastic section are parallel to the transverse centerline;
wherein each of the plurality of second elastics in the second elastic section are parallel to the transverse centerline;
wherein at least a portion of the second plurality of elastics of the second elastic section or a portion of the third plurality of elastics of the third elastic section are disposed between the transverse seam axis and the transverse centerline;
wherein the first elastic section of the front belt portion comprises a first force zone, a second force zone, and a third force zone;
wherein the second elastic section of the front belt portion comprises a fourth force zone, fifth force zone, and a sixth force zone;
wherein the individual force zones each comprise an individual force profile;
wherein the force profile of the first zone, second zone, or third zone does not equal the force profile of the fourth zone, fifth zone, or sixth zone; and
wherein the absorbent article comprises a leg elastic material extending along a side edge of the absorbent main chassis.

2. The absorbent article of claim 1 , wherein first plurality of elastics and the second plurality of elastics comprises elastic strands exhibiting a linear density and a force prestrain.

3. The absorbent article of claim 2 , wherein at least one of the elastic strands is aligned in a curved fashion forming an acute angle with the longitudinal centerline of the absorbent article.

4. The absorbent article of claim 2 , wherein the front belt force profile is achieved by changing the linear density of the elastic strands.

5. The absorbent article of claim 1 , wherein the first elastic section force profile is different than the second elastic section force profile.

6. The absorbent article of claim 1 , wherein the front belt and the back belt refastenably connect at one or both of the first seam and the second seam.

7. The absorbent article of claim 1 , wherein the front belt and the back belt refastenably connect to the absorbent main body.

8. The absorbent article of claim 1 , wherein the surface extending from a first waist edge to a longitudinally opposing second waist edge folds at the front waist edge forming a portion of the of an inner surface of the front waist belt.

9. The absorbent article of claim 1 , wherein a portion of the second plurality of elastics in the second section are along a leg cutout.

10. The absorbent article of claim 1 , wherein the third force profile and the fourth force profile are the same.

11. The absorbent article of claim 1 , wherein the fourth force profile is greater than at least one of the first force profile, the second force profile, or the third force profile.

12. An absorbent article having a longitudinal centerline, a transverse centerline, a front region, a crotch region, and a back region,
the absorbent article comprising a main chassis portion comprising an absorbent main body, and a waist portion; the waist portion comprising a belt portion; the belt portion comprising a front belt portion and a back belt portion; the absorbent main body comprising an absorbent core;
wherein the front belt and the back belt portions are joined at side edges to form a first seam comprising a first end and a second end and a second seam comprising a first end and a second end;
wherein the first ends of the first and second seams are disposed immediately adjacent to a waist opening, and wherein the second ends of the first and second seams are disposed immediately adjacent to a first leg opening and a second leg opening;
wherein a transverse seam axis intersects each of the second ends of the first and second seams, and runs substantially parallel to the transverse centerline;
wherein the front belt portion comprises a first elastic section comprising a first plurality of elastics exhibiting a first force profile and a second elastic section comprising a second plurality of elastics exhibiting a second force profile;
wherein a surface of the front belt portion and a surface of the back belt portion is formed from a first belt layer extending from a first waist edge in a first waist region through the crotch region to a longitudinally opposing second waist edge in a second waist region and forms at least a portion of an outer surface of the absorbent article;
wherein the surface extending from a first waist edge to a longitudinally opposing second waist edge folds at the front waist edge forming a portion of the of an inner surface of the front waist belt;
wherein the distance between the absorbent main body and the front waist edge is greater than the distance between the absorbent main body and the back waist edge;
wherein the back belt comprises a third plurality of elastics;
wherein the at least a portion of the third plurality of elastics of the back belt overlap the at least a portion of the absorbent core;
wherein each of the first plurality of elastics in the first elastic section are parallel to the transverse centerline;
wherein each of the plurality of second elastics in the second elastic section are parallel to the transverse centerline;
