Absorbent garments with multipart liner having varied stretch properties
View Patent ↗Absorbent articles with stretch direction properties are disclosed, having at least three stretch zones. A first edge zone and a second edge zone are separated by a middle zone. The middle zone, which may the same length as each edge zone, has different stretch-direction characteristics than the edge zones. The middle zone may stretch in a single direction, whereas the edge zones may stretch in a different single direction or in bi- or multi-axial directions. The flaps may be created from the edge zones. Through this construction, the absorbent article exhibits improved fit and appearance.
1. An absorbent article comprising:
an outer cover comprising a stretchable material;
a stretchable bodyside liner joined to the outer cover in a superimposed relation; and
an absorbent structure positioned in between the outer cover and the liner;
wherein the outer cover, liner and absorbent structure form a chassis having a longitudinal axis and a lateral axis, wherein the liner comprises three zones across a lateral direction, the three zones comprising a first edge zone, a middle zone, and a second edge zone, and wherein the middle zone is a uniaxial stretch material that stretches in a first direction, and the respective first and second edge zones stretch in a second direction that is different than the first direction and cannot stretch in the first direction.
2. The absorbent article of claim 1 wherein the respective first and second edge zones are biaxial.
3. The absorbent article of claim 1 the respective first and second edge zones are multiaxial.
4. The absorbent article of claim 1 wherein the uniaxial stretch material stretches substantially in the longitudinal direction.
5. The absorbent article of claim 1 wherein the uniaxial stretch material stretches substantially in the lateral direction.
6. The absorbent article of claim 5 wherein the outer cover is elastic.
7. The absorbent article of claim 5 wherein the liner is elastic.
8. The absorbent article of claim 5 wherein the absorbent structure is attached to the chassis by a longitudinally oriented bond.
9. The absorbent article of claim 1 wherein the outer cover comprises a biaxial material.
10. The absorbent article of claim 1 wherein the stretchable bodyside liner includes a first waist edge and a second waist edge, the second waist edge being opposite from the first waist edge, and wherein the first edge zone and the second edge zone extend substantially from the first waist edge to the second waist edge.
11. An absorbent article comprising:
an outer cover comprising a stretchable material;
a stretchable bodyside liner joined to the outer cover in a superimposed relation, the stretchable bodyside liner including a first waist edge and a second waist edge, the second waist edge being opposite from the first waist edge; and
an absorbent structure positioned in between the outer cover and the liner;
wherein the outer cover, liner and absorbent structure form a chassis having a longitudinal axis and a lateral axis, wherein the liner comprises three zones across a lateral direction, the three zones comprising a first edge zone, a middle zone, and a second edge zone, wherein the first edge zone and the second edge zone extend substantially from the first waist edge to the second waist edge, and wherein the middle zone is substantially limited to stretching in a direction parallel to the lateral axis, and the respective first and second edge zones can stretch in a direction that is not parallel to the lateral axis.
12. The absorbent article of claim 11 wherein the respective first and second edge zones are biaxial.
13. The absorbent article of claim 11 the respective first and second edge zones are multiaxial.
14. The absorbent article of claim 11 wherein the first edge zone and the second edge zone cannot stretch in the direction parallel to the lateral axis.
15. A disposable absorbent article comprising:
an outer cover; and
a stretchable bodyside liner joined to the outer cover in a superimposed relation;
wherein the outer cover and liner form a chassis having a longitudinal axis and a lateral axis, wherein the liner comprises three zones across a lateral direction, the three zones comprising a first edge zone, a middle zone having opposite longitudinal sides, and a second edge zone, and wherein the middle zone is substantially limited to stretching in a direction parallel to the lateral axis, and the respective first and second edge zone can stretch in multiple directions, the multiple directions not including the direction parallel to the lateral axis.
16. The disposable absorbent article of claim 15 wherein the outer cover is elastic.
17. The disposable absorbent article of claim 16 wherein the liner is elastic.
18. The disposable absorbent article of claim 15 further comprising a pair of flaps extending along each of the longitudinal sides of the middle zone.
19. The disposable absorbent article of claim 18 wherein the first edge zone and the second edge zone overlap the middle zone for forming the pair of flaps.
20. The disposable absorbent article of claim 15 wherein the outer cover is biaxially stretchable.
21. The disposable absorbent article of claim 20 further comprising a stretchable absorbent structure positioned in between the outer cover and the liner.
22. The disposable absorbent article of claim 21 wherein the absorbent structure is attached to the article by a bond oriented in the longitudinal direction.
23. The disposable absorbent article of claim 13 wherein the stretchable bodyside liner includes a first waist edge and a second waist edge, the second waist edge being opposite from the first waist edge, and wherein the first edge zone and the second edge zone extend substantially from the first waist edge to the second waist edge.
