Abstract
A disposable absorbent article is provided which includes a substantially liquid-impermeable, stretchable outer cover, a liquid permeable, stretchable top surface, and an absorbent body located between the outer cover and the top surface. The stretchable top surface can further include a first zone and a second zone. The stretchable outer cover can be configured to provide a first level of elongation when subjected to a tensile force of 100 gmf per inch (per 2.54 cm) of width according to the Material Elongation and Deformation Tensile Test set forth herein, while the first zone provides a second level of elongation that is less than the first level of elongation.
Claims44
A disposable absorbent article which defines a front waist section, a rear waist section, an intermediate section which extends between and connects said waist sections, a pair of laterally opposed side edges, a pair of longitudinally opposed waist edges, a longitudinal direction and a lateral direction, said absorbent article comprising:
- a) a substantially liquid-impermeable stretchable outer cover configured to provide a first level of elongation;
- b) a liquid permeable stretchable top surface attached to said stretchable outer cover;
- said stretchable top surface having a first zone that is configured to provide a second level of elongation that is less than said first level of elongation, said first zone of said top surface is provided by a stretchable bodyside liner and a means for restricting the stretchability of said stretchable bodyside liner;
- c) at least one containment component attached to said liquid permeable top surface;
- and
- d) an absorbent body located between said stretchable outer cover and said stretchable top surface.
A pant-like, prefastened, disposable absorbent article which defines a front waist section, a rear waist section, an intermediate section which extends between and connects said waist sections, a pair of laterally opposed side edges, a pair of longitudinally opposed waist edges, a longitudinal direction and a lateral direction, said pant-like absorbent article comprising:
- a) a substantially liquid-impermeable stretchable outer cover configured to provide a first level of elongation;
- b) a liquid permeable stretchable top surface attached to said stretchable outer cover;
- said top surface having a first zone that is configured to provide a second level of elongation that is less than said first level of elongation said first zone of said top surface is provided by a stretchable bodyside liner and a means for restricting the stretchability of said stretchable bodyside liner;
- c) at least one containment component attached to said liquid permeable top surface;
- d) an absorbent body located between said stretchable outer cover and said stretchable top surface;
- and
- e) a pair of fasteners refastenably attaching said laterally opposed side edges in said front waist section to said laterally opposed side edges in said rear waist section to provide said pant-like, prefastened absorbent article prior to packaging.
A disposable absorbent article which defines a front waist section, a rear waist section, an intermediate section which extends between and connects said waist sections, a pair of laterally opposed side edges, a pair of longitudinally opposed waist edges, a longitudinal direction and a lateral direction, said absorbent article comprising:
- a) a substantially liquid-impermeable stretchable outer cover configured to provide a first level of elongation;
- b) a liquid permeable stretchable bodyside liner attached to said stretchable outer cover;
- c) a pair of containment flaps attached to said liquid permeable stretchable bodyside liner;
- d) a surge layer attached to said liquid permeable stretchable bodyside liner;
- and
- e) an absorbent body located between said stretchable outer cover and said stretchable bodyside liner;
- wherein said stretchable bodyside liner and said surge layer combine to provide a first zone that is configured to provide a second level of elongation that is less than the first level of elongation.
A disposable absorbent article which defines a front waist section, a rear waist section, an intermediate section which extends between and connects said waist sections, a pair of laterally opposed side edges, a pair of longitudinally opposed waist edges, a longitudinal direction and a lateral direction, said absorbent article comprising:
- a) a substantially liquid-impermeable stretchable outer cover;
- b) a liquid permeable stretchable top surface attached to said stretchable outer cover;
- said stretchable top surface having a first zone and a second zone wherein said second zone provides an elongation that is at least about 20 percent and said first zone provides an elongation that is less than 20 percent when subjected to a tensile force of 100 gmf per inch (per 2.54 cm) of width;
- c) at least one containment component attached to said liquid permeable top surface;
- and
- d) an absorbent body located between said stretchable outer cover and said stretchable top surface.
