Abstract

Disclosed is an absorbent article, such as a sanitary napkin, incontinent device, or the like. The absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core disposed between the topsheet and the backsheet. The absorbent article further comprises a pair of longitudinally extending cuffs disposed on the body surface of the topsheet on each side of a longitudinal centerline of the absorbent article The cuffs comprise an elastic member and a resilient member and are joined to at least one of the topsheet and the backsheet in a longitudinally elastically elongated state. The elastic member preferably comprises first and second regions which are visibly distinct from each other. The first region comprises at least two substantially planar portions and the second comprises a plurality of raised, rib-like elements. In a particularly preferred embodiment of the present invention, at least one of the substantially planar portions of the first region of the bands of web material extends in a substantially longitudinal direction and at least one other of the substantially planar portions of the first region of the elastic member is oriented at an angle with respect to the longitudinal direction. The resilient member is soft yet sufficiently resilient to resist the compressive forces applied to the cuffs by normal wearer movement. The resilient member is positioned sufficiently close to the body surface of the topsheet to also provide resistance to bending that may also be caused by normal bodily movements.

Claims

1. An absorbent article having a longitudinal centerline defining a longitudinal direction, a pair of opposing side edges, a pair of ends, and a longitudinally extending central portion, said central portion defining a plane, said absorbent article comprising:

a liquid pervious topsheet;

a liquid impervious backsheet joined to said topsheet;

an absorbent core positioned between said topsheet and said backsheet; and

a pair of longitudinally extending cuffs, each of said cuffs having a proximal edge and a distal edge, one of said cuffs being disposed adjacent each of said side edges of said absorbent article in a longitudinally elongated state, with said proximal edge of each of said cuffs being joined to at least one of said topsheet or said backsheet, said cuffs comprising;

a resilient member which provides compression resistance and bending resistance to said cuffs; and

an elastic member, said elastic member comprising an elastically extensive film material having a first region and a second region, said first and second regions of said elastic member being visibly distinct from each other wherein said second region comprises a plurality of raised rib-like elements and said first region comprises at least two substantially planar regions which provides a contractive force, said elastic member being folded about said resilient member in a C-fold, wherein said contractive force causes said ends to extend upwardly inclinedly away from said plane of said central portion and said distal edges to extend upwardly away from said topsheet along both of said side edges of said central portion.

2. An absorbent article according to claim 1 wherein at least one of said substantially planar first regions is oriented generally in the longitudinal direction, at least one other substantially planar first region is oriented at an angle to said longitudinal direction, and said plurality of raised rib-like elements define ridges that are oriented generally in the transverse direction.

3. An absorbent article according to claim 2 wherein said angle is between about 15 degrees and about 45 degrees.

4. An absorbent article according to claim 1 wherein said resilient member comprises a fibrous assembly.

5. An absorbent article according to claim 4 wherein said fibrous assembly is air laid.

6. An absorbent article according to claim 4 wherein said fibrous assembly is wet laid.

7. An absorbent article according to claim 1 wherein said resilient member comprises a foam.

8. A n absorbent article according to claim 7 wherein said foam comprises a HIPE foam.

9. An absorbent article according to claim 7 wherein said foam comprises a blown foam.

10. An absorbent article according to claim 1 wherein said resilient member comprises a scrim.

11. An absorbent article according to claim 10 wherein said scrim has been rolled about a longitudinally extending axis such that it has a cylindrical configuration.

12. An absorbent article according to claim 10 wherein said scrim has been wrapped about a longitudinally extending axis in a spiral configuration.

13. An absorbent article according to claim 10 wherein said scrim has been provided with a sinusoidal configuration.

14. An absorbent article having a longitudinal centerline defining a longitudinal direction, a pair of opposing side edges, a pair of ends, and a longitudinally extending central portion, said central portion defining a plane, said absorbent article comprising:

a liquid pervious topsheet;

a liquid impervious backsheet joined to said topsheet;

an absorbent core positioned between said topsheet and said backsheet; and

a pair of longitudinally extending cuffs, each of said cuffs having a proximal edge and a distal edge, one of said cuffs being disposed adjacent each of said side edges of said absorbent article in a longitudinally elongated state, with said proximal edge of each of said cuffs being joined to a least one of said topsheet or said backsheet, said cuffs comprising;

a resilient member which provides compression resistance and bending resistance to said cuffs, wherein said resilient member comprises a foam; and

an elastic member comprising a SELF web, which provides a contractive force when elongated, said elastic member being folded about said resilient member in a C-fold, wherein said contractive force causes said ends to extend upwardly inclinedly away from said plane of said central portion and said distal edges to extend upwardly away from said topsheet along both side edges of said central portion.

15. An absorbent article according to claim 14 wherein said absorbent article further comprises a pair of laterally extending flaps, wherein a flap is joined to each of said side edges in at least said central region and said extends outward therefrom in a lateral direction.
