Abstract

An absorbent article has a first waist region, a second waist region, a crotch region disposed between the first and second waist regions; and a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. The article also includes a primary fastening system and secondary fastening system. The primary fastening system has a primary fastening component disposed in the second waist region and a primary receiving component disposed in the first waist region and operatively engageable with the primary fastening component. The secondary fastening system includes a secondary fastening component disposed in the first waist region and a secondary receiving component disposed in the second waist region and operatively engageable with the secondary fastening component. The article further includes a decoupled zone disposed longitudinally inboard of the secondary fastening component.

Claims (43)

1. An absorbent article comprising:

a first waist region, a second waist region, a crotch region disposed between the first and second waist regions;

a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet;

a primary fastening system and a secondary fastening system, wherein the primary fastening system comprises a primary fastening component disposed in the second waist region and a primary receiving component disposed in the first waist region and operatively engageable with the primary fastening component; and wherein the secondary fastening system comprises a secondary fastening component disposed in the first waist region and a secondary receiving component disposed in the second waist region and operatively engageable with the secondary fastening component;

a composite comprising one or more layers of a lateral extension element and the chassis;

an anchoring zone wherein the one or more layers of the composite are joined, the anchoring zone being defined by a perimeter; and

a decoupled zone adjacent to the anchoring zone and disposed outside of the perimeter,

wherein at least a portion of the secondary fastening component is disposed in the anchoring zone and wherein a portion of the composite is longitudinally inboard of the secondary fastening component and within the decoupled zone, and

wherein a portion of the composite is disposed laterally outboard of the secondary fastening component and is within the decoupled zone.

2. The absorbent article of claim 1 wherein the decoupled zone comprises a zone of detachment.

3. The absorbent article of claim 1 wherein the decoupled zone comprises a zone of weakness.

4. The absorbent article of claim 1 wherein the lateral extension element comprises one or more layers of a combination belt structure.

5. The absorbent article of claim 1 wherein at least about 25% of the secondary fastening component is disposed within the anchoring zone.

6. The absorbent article of claim 1 wherein a portion of the composite is disposed laterally inboard of the secondary fastening component and is within the decoupled zone.

7. The absorbent article of claim 1 wherein the perimeter comprises at least one straight line portion.

8. The absorbent article of claim 1 wherein the perimeter comprises at least one curved portion.

9. The absorbent article of claim 1 wherein the perimeter comprises a plurality of discrete bond sites.

10. The absorbent article of claim 1 further comprising an elastic waistband.

11. An absorbent article comprising:

a first waist region, a second waist region, a crotch region disposed between the first and second waist regions;

a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet;

a primary fastening system and a secondary fastening system, wherein the primary fastening system comprises a primary fastening component disposed in the second waist region and a primary receiving component disposed in the first waist region and operatively engageable with the primary fastening component; and

a composite comprising one or more layers of the chassis, wherein the one or more layers of the composite are joined in an anchoring zone and a decoupled zone adjacent to the anchoring zone,

wherein the secondary fastening system comprises a secondary fastening component at least partially disposed in a bending resistant zone of the first waist region and a secondary receiving component disposed in the second waist region and operatively engageable with the secondary fastening component;

wherein the bending resistant zone comprises a stiffening component;

wherein the stiffening component is in at least partial overlapping relationship with the secondary fastening component;

wherein the bending resistant zone comprises a stiffness of at least 0.2 N/mm; and

wherein a portion of the composite is disposed laterally outboard of the secondary fastening component and is within the decoupled zone.

12. The absorbent article of claim 11 further comprising a lateral extension element, wherein the lateral extension element is in at least partial overlapping relationship with the bending resistant zone and wherein the lateral extension element comprises a first lateral edge and a second lateral edge, wherein the secondary fastening component is disposed between the first and second lateral edges.

13. The absorbent article of claim 11 , wherein the stiffening component is selected from the group consisting of folded material, a nonwoven, a film, adhesive and combinations thereof.

14. The absorbent article of claim 11 further comprising an elastic waistband.

15. An absorbent article comprising:

a first waist region, a second waist region, a crotch region disposed between the first and second waist regions;

a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and

a primary fastening system and a secondary fastening system, wherein the primary fastening system comprises a primary fastening component disposed in the second waist region and a primary receiving component disposed in the first waist region and operatively engageable with the primary fastening component; and

wherein the secondary fastening system comprises a secondary fastening component disposed in the first waist region and a secondary receiving component disposed in the second waist region and operatively engageable with the secondary fastening component;

a composite comprising an anchoring zone and a decoupled zone;

a lateral extension element joined to the chassis in the first waist region in the anchoring zone defined by a perimeter;

wherein the anchoring zone comprises a varied width, as measured in a lateral direction, having a maximum width, W AZmax , and a minimum width, W AZmin , wherein the maximum width, W AZmax , is in an area that is longitudinally outboard of the minimum width, and

wherein a portion of the composite is disposed laterally outboard of the secondary fastening component and is within the decoupled zone.

16. The absorbent article of claim 15 wherein the perimeter comprises a curvilinear portion.

17. The absorbent article of claim 15 wherein the perimeter comprises a straight portion.

18. The absorbent article of claim 15 wherein the first waist region comprises a bending resistant zone having a Stiffness of at least 0.2 N/mm.
