Abstract
An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions. The article further includes a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and an ear. The ear includes a laminate having a first nonwoven and second nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate comprises a plurality of ultrasonic bonds. The ear also has a first inelastic region and an elastic region. The ear is joined to the chassis in the first inelastic region, and a fastening system is joined to the ear in the elastic region.
Claims19
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 discrete ear joined to the chassis and comprising:
- an outboard ear edge;
- a laminate comprising a first nonwoven and second nonwoven and an elastomeric material sandwiched between said first and second nonwovens, wherein the laminate further comprises a plurality of ultrasonic bonds;
- and
- a first inelastic region and an elastic region, wherein the ear is joined to the chassis in the first inelastic region at a chassis attachment bond and wherein a fastening system is joined to the ear at a fastener attachment bond only in the elastic region, wherein the fastening system comprises fastening elements disposed outboard of the outboard ear edge, and wherein the fastening system overlaps with the elastic region in an overlap by a maximum distance of 5% of a width of the elastic region such that the fastening system comprises an average load at break of 24 N or greater determined using a tensile test method, wherein the fastener attachment bond is disposed in the overlap;
- and
- wherein the ear comprises a Length Ratio of 1.75 to 3, wherein the Length Ratio is a maximum length of the ear at an outboard edge of the chassis bond divided by a maximum length of the fastener attachment bond.
