Abstract
A disposable article includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and an elasticized waist gasketing element. The elasticized waist gasketing element has a lateral outboard edge and a longitudinal array of elastic members. The longitudinal array includes a primary waist elastic member disposed inboard of the waist edge by a minimum longitudinal distance A, a secondary waist elastic member disposed inboard of the primary waist elastic member by a minimum longitudinal distance B. The waist gasketing element comprises a Force Ratio of at least about 1.1.
Claims20
A disposable absorbent article for wearing about the lower torso of a wearer, the disposable absorbent article comprising:
- a first waist region having a first waist edge, a second waist region having a second waist edge, a crotch region disposed between the first and second waist regions;
- and a first longitudinal edge and a second longitudinal edge;
- a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet;
- and
- an elasticized waist gasketing element joined to the chassis in one of the first or the second waist regions, wherein the elasticized waist gasketing element comprises a lateral outboard edge and a longitudinal array of elastic members, the longitudinal array of elastic members comprising:
- a primary waist elastic member disposed inboard of the respective first or second waist edge by a minimum longitudinal distance A, and
- a secondary waist elastic member disposed inboard of the primary waist elastic member by a minimum longitudinal distance B,
- wherein the waist gasketing element comprises a Force Ratio of at least about 1.1.
A disposable absorbent article for wearing about the lower torso of a wearer, the disposable absorbent article comprising:
- a first waist region having a first waist edge, a second waist region having a second waist edge, a crotch region disposed between the first and second waist regions;
- and a first longitudinal edge and a second longitudinal edge;
- a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet;
- and
- an elasticized waist gasketing element joined to the chassis in the second waist region, wherein the elasticized waist gasketing element comprises waist gasketing element pocket and a longitudinal array of elastic members comprising:
- a first outboard pocket elastic member disposed inboard of the second waist edge and comprising an outboard pocket contraction force, and
- a second inboard pocket elastic member disposed inboard of the first outboard pocket waist elastic member, wherein the second inboard pocket waist elastic member comprises an inboard pocket contraction force, and
- wherein the inboard pocket contraction force is greater than the outboard contraction force.
A disposable absorbent article for wearing about the lower torso of a wearer, the disposable absorbent article comprising:
- a first waist region having a first waist edge, a second waist region having a second waist edge, a crotch region disposed between the first and second waist regions;
- and a first longitudinal edge and a second longitudinal edge;
- a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet;
- a bending line disposed in one of the first or the second waist regions;
- and
- an elasticized waist gasketing element joined to the chassis in the one of the first or the second waist regions and overlaying the bending line, wherein the elasticized waist gasketing element comprises:
- a primary outboard set of elastic members disposed outboard of the bending line and comprising an aggregate primary moment of force, ΣMp;
- and
- a secondary inboard set of elastic members disposed inboard of the bending line and comprising an aggregate secondary moment of force, ΣMs;
- wherein the aggregate secondary moment of force, ΣMs, is greater than the aggregate primary moment of force, ΣMp.
