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 force profile and a second elastic section comprising a second force profile;
wherein the first elastic section comprises a first plurality of elastics comprising elastic strands having a first average spacing;
wherein the second elastic section comprises a second plurality of elastics comprising elastic strands having a second average spacing;
wherein the back belt portion comprises a third elastic section comprising a third force profile and a fourth elastic section comprising a fourth force profile;
wherein the third elastic section comprises a third plurality of elastics comprising elastic strands having a third average spacing;
wherein the fourth elastic section comprises a fourth plurality of elastics comprising elastic strands having a fourth average spacing;
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 first waist edge forming a portion of the of an inner surface of the front waist belt;
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 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 absorbent article comprises a leg elastic material extending along a side edge of the absorbent main chassis;
wherein a portion of the second plurality of elastics in the second section are along a leg cutout; and
wherein at least one of the elastic strands of the second plurality of elastics is aligned in a curved fashion forming an acute angle with the longitudinal centerline of the absorbent article; and
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; and
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.

2. The absorbent article of claim 1 , wherein the elastic strands exhibit a linear density and a force prestrain.

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

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

5. The absorbent article of claim 1 , wherein main chassis has a generally rectangular shape.

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 absorbent core comprises a fluid acquisition component, a fluid distribution component, and a fluid storage component.

9. The absorbent article of claim 1 , wherein the distance between the absorbent main body and the first waist edge is greater or less than the distance between the absorbent main body and the second waist edge.

10. The absorbent article of claim 1 , wherein the third average spacing is greater than at least one of the first average spacing, the second average spacing, or the fourth average spacing.

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