Abstract
An outer cover for a disposable absorbent article. The outer cover includes an elastic material joined to an extensible material to form a laminate. At least two different areas of the laminate are simultaneously activated in different directions by a single pair of intermeshing activation rolls. At least a portion of the two different areas of activation on the outer cover are spatially separated by a buffer zone.
Claims20
An outer cover for a disposable absorbent article, the outer cover comprising an elastic material and an extensible non-woven material, the outer cover further comprising:
- a. a longitudinal direction and a lateral direction orthogonal thereto, a first waist region including a first end edge, a second waist region including a second end edge longitudinally opposed to the first end edge, a crotch region disposed between the first and second waist regions, first and second laterally opposing side edges;
- b. a first leg band portion disposed adjacent to the first side edge and a second leg band portion disposed adjacent to the second side edge, the first and second leg band portions extending from the first waist region through the crotch region and into the second waist region, the first and second leg band portions being activated in a first direction by mechanical deformation such that the extensible non-woven material is permanently elongated, wherein the first and second leg band portions are activated from the first waist region through the crotch region and into the second waist region;
- c. a body portion disposed in the first and second waist regions and the crotch region, the body portion being activated in a second direction which is different than the first direction by mechanical deformation such that the extensible non-woven material is permanently elongated, wherein the body portion is activated from the first waist region through the crotch region and into the second waist region;
- d. a first buffer zone disposed between activated portions of the first leg band portion and the body portion, the first buffer zone contiguously extending from the first waist region through the crotch region and into the second waist region;
- and
- e. a second buffer zone disposed between activated portions of the second leg band portion and the body portion, the second buffer zone contiguously extending from the first waist region through the crotch region and into the second waist region.
A disposable absorbent article intended to be worn about the lower waist of wearer the disposable absorbent article comprising a topsheet, an outer cover, and an absorbent core disposed therebetween, a substantially circular shaped leg opening and an elastic leg band encircling the leg opening, wherein the outer cover comprises an elastic material and an extensible non-woven material, the outer cover further comprising:
- a. a longitudinal direction and a lateral direction orthogonal thereto, a first waist region including a first end edge, a second waist region including a second end edge longitudinally opposed to the first end edge, a crotch region disposed between the first and second waist regions, first and second laterally opposing side edges;
- b. a first leg band portion disposed adjacent to the first side edge and a second leg band portion disposed adjacent to the second side edge, the first and second leg band portions extending from the first waist region through the crotch region and into the second waist region, the first and second leg band portions being activated in a first direction by mechanical deformation such that the extensible non-woven material is permanently elongated, wherein the first and second leg band portions are activated from the first waist region through the crotch region and into the second waist region;
- c. a body portion disposed in the first and second waist regions and the crotch region, the body portion being activated in a second direction which is different than the first direction by mechanical deformation such that the extensible non-woven material is permanently elongated, wherein the body portion is activated from the first waist region through the crotch region and into the second waist region;
- d. a first buffer zone disposed between activated portions of the first leg band portion and the body portion, the first buffer zone contiguously extending from the first waist region through the crotch region and into the second waist region;
- and
- e. a second buffer zone disposed between activated portions of the second leg band portion and the body portion, the second buffer zone contiguously extending from the first waist region through the crotch region and into the second waist region;
- wherein the leg opening is elastically extensible around substantially the entire circumference of the leg opening and at least one of the first and second waist panels exhibit elastic extensibility in the lateral direction.
