Abstract
Absorbent articles having a unique elastic feature improving the dynamic fit as well as containment characteristics. The elastic feature preferably includes an elastomeric member and a nonelastic web; a portion of the nonelastic web coincides with at least a portion of the elastomeric member; this portion of the nonelastic web being mechanically prestrained. Mechanical prestraining of the nonelastic web improves not only the extension of the elastomeric member, but also the heat-shrink contraction of preferred elastomeric members.
Claims15
A disposable absorbent article comprising:
- liquid pervious topsheet;
- a liquid impervious backsheet joined with said topsheet;
- an absorbent core having side edges and waist edges, said absorbent core being positioned between said topsheet and said backsheet;
- and
- an elastic feature extending outwardly from one of said edges of said absorbent core, said elastic feature comprising a nonelastic web and an elastomeric member joined with said nonelastic web such that a portion of said nonelastic web coincides with at least a portion of said elastomeric member, said portion of said nonelastic web coinciding with said elastomeric member being mechanically prestrained such that said nonelastic web assumes a pattern of strained ribs and unstrained gaps.
A disposable absorbent article comprising:
- a liquid pervious topsheet;
- a liquid impervious backsheet joined with said topsheet;
- an absorbent core having side edges and waist edges, said absorbent core being positioned between said topsheet and said backsheet;
- and
- an elastic feature extending outwardly from one of said edges of said absorbent core, said elastic feature comprising a segment of said topsheet which extends beyond one of said edges of said absorbent core and an elastomeric member joined with said topsheet such that a portion of said topsheet segment coincides with at least a portion of said elastomeric member, said portion of said topsheet coinciding with said elastomeric member being mechanically prestrained such that said portion of said topsheet assumes a pattern of strained ribs and unstrained gaps.
