Abstract
A disposable absorbent article may include a first waist region, a second waist region, a crotch region disposed between the first and the second waist regions, and a chassis having a topsheet, backsheet, absorbent core, and chassis periphery. The chassis periphery has a varying width, Wv. The varying width Wv has a first maximum width, W1, in the first waist region, a minimum width, Wmin, in the crotch region, and a second maximum width, W2, in the second waist region, wherein W1 is greater than W2.
Claims22
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;
- and a longitudinal centerline;
- a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet;
- and
- a back ear joined to the chassis in the second waist region;
- wherein the first longitudinal edge, second longitudinal edge, first waist edge and second waist edge define a chassis periphery and the chassis periphery comprises a varying width, Wv, the varying width Wv comprising a first maximum width, W1, in the first waist region, a minimum width, Wmin, in the crotch region, and a second maximum width, W2, in the second waist region, wherein W1is greater than W2 and
- wherein the backsheet comprises a polymeric film layer having a polymeric maximum lateral width, Wpoly, wherein the polymeric maximum lateral width, Wpoly, is less than the minimum width, Wmin.
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;
- and a longitudinal centerline;
- a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet;
- wherein the first longitudinal edge, second longitudinal edge, first waist edge and second waist edge define a chassis periphery and the chassis periphery comprises a varying width, Wv, the varying width Wv comprising a first maximum width, W1, in the first waist region, a minimum width, Wmin, in the crotch region, and a second maximum width, W2, in the second waist region, wherein W1 is greater than W2;
- and
- an elasticized component joined to the chassis, and comprising an elasticized region and wherein the elasticized region comprises an attachment zone, a first elastic member, and second elastic member and wherein in the attachment zone:
- the first elastic member is joined to the elasticized component by two attachment intervals separated by an unattached span;
- and
- the second elastic member is continuously joined to the elasticized component.
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;
- and a longitudinal centerline;
- a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet;
- and
- a back ear joined to the chassis in the second waist region;
- wherein the first longitudinal edge, second longitudinal edge, first waist edge and second waist edge define a chassis periphery and the chassis periphery comprises a varying width, Wv, the varying width Wv comprising a first maximum width, W1, in the first waist region, a minimum width, Wmin, in the crotch region, and a second maximum width, W2, in the second waist region, wherein W1 is greater than W2, and
- wherein the first waist region comprises a landing zone disposed a lateral distance of about 2 mm or less from the longitudinal centerline.
