Abstract
Absorbent articles having a unique elastic feature improving the dynamic fit as well as containment characteristics. The elastic feature preferably comprises an elastomeric member and a segment of the backsheet; a portion of the backsheet segment coincides with at least a portion of the elastomeric member; this portion of the backsheet segment being mechanically prestrained. Mechanical prestraining of the backsheet segment improves not only the extension of the elastomeric member, but also the heat-shrink contraction of preferred elastomeric members.
Claims14
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 backsheet which extends beyond said edge of said absorbent core and an elastomeric member joined with said backsheet such that a portion of said backsheet segment coincides with at least a portion of said elastomeric member, said portion of said backsheet coinciding with said elastic member being mechanically prestrained to permanently elongate portions of said backsheet prior to combining said backsheet with said elastomeric member.
