A liquid impervious seal for extensible absorbent articles for wearing in an undergarment, such as sanitary napkins, panty liners, incontinence pads, and the like, is disclosed. The absorbent articles are typically formed from the following components: a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, and an absorbent core positioned between the topsheet and backsheet. The components forming the absorbent article are held together by use of an extensible liquid impervious seal having a sinusoidal configuration. |

DETAILED DESCRIPTION The present invention provides a multi-directionally extensible, and preferably elastically extensible, absorbent article for wearing in an undergarment, such as a sanitary napkin, panty liner, incontinence device, or the like.
The multi-directionally extensible absorbent article has a longitudinal centerline, a transverse centerline, a pair of longitudinal side edges, a pair of end edges, a first end region, a second end region, and a central region between the first and second end regions.
The multi-directionally extensible absorbent article preferably has a main body portion that comprises at least two regions that are extensible in different directions, and at least one of these regions, and preferably two or more of these regions, are capable of 25% elongation under forces of less than or equal to about 500 grams.
The main body portion of the multi-directionally extensible absorbent article preferably comprises a multi-directionally extensible liquid pervious topsheet, a multi-directionally extensible liquid impervious backsheet at least partially peripherally joined to the topsheet, and a multi-directionally extensible absorbent core positioned between the topsheet and the backsheet.
In one preferred embodiment, the main body portion of the multi-directionally extensible absorbent article has a central region that is primarily extensible in the transverse direction.
The first and second end regions preferably each comprise three regions of extensibility: a first region of extensibility, a second region of extensibility, and a third region of extensibility.
The first region of extensibility in the end regions is disposed along at least a portion of the longitudinal centerline adjacent one of the end edges of the main body portion.
The first region of extensibility is primarily extensible in the transverse direction.
The second region of extensibility is disposed laterally outward of at least part of the first region of extensibility on one side of said first region of extensibility, and extends toward one of the longitudinal side edges of the absorbent article
