Benefits of technology
"The present invention is about an absorbent article that has a specific shape and is designed to fit the body. It has a layered portion with a layer that faces the body and a layer that faces the garment. This makes it easy to wear and comfortable. The absorbent article can also have an absorbent layer and a transfer layer. This invention provides a better fit and comfort for the wearer."
Problems solved by technology
That is, movement by the wearer may cause the absorbent article to conform to the geometry of the space between the wearer's thighs.
In contrast, if the absorbent article is stiff to begin with, the wearer may experience discomfort and be conscious of the absorbent article.
Additionally, if such an article bunches, there is a tendency to maintain its resulting distorted shape, thereby providing inadequate protection.
However, the above absorbent articles are not fully flexible and do not adapt to the body as an undergarment alone does, thereby sacrificing comfort, protection and discretion.

example
[0046] Samples of commercially available pantiliners were compared to samples of the present invention and samples from the crotch portion of an undergarment.
[0047] Peak bending stiffness is determined by a test that is modeled after the ASTM D 4032-82 CIRCULAR BEND PROCEDURE, the procedure being considerably modified and performed as follows. The CIRCULAR BEND PROCEDURE is a simultaneous multi-directional deformation of a material in which one face of a specimen becomes concave and the other face becomes convex. The CIRCULAR BEND PROCEDURE gives a force value related to flexural resistance, simultaneously averaging stiffness in all directions.
[0048] The apparatus necessary for the CIRCULAR BEND PROCEDURE is a modified Circular Bend Stiffness Tester, having the following parts: [0049] 1. A smooth-polished steel plate platform, which is 102.0 mm by 102.0 by 6.35 mm having an 18.75 mm diameter orifice. The lap edge of the orifice should be at a 45 degree angle to / a depth of 4.75 mm...

Abstract
An absorbent article having a silhouette including a first end, a second end, wherein the second end being in opposite relation to the first end, and a first longitudinally extending edge opposed to a second longitudinally extending edge, the first and second longitudinally extending edges connecting the first end and the second end; and a layered portion having a body-facing layer and a garment-facing layer, wherein the absorbent article is drapeable.
Description
CROSS REFERENCE TO RELATED APPLICATION [0001] The present application is a divisional application of U.S. patent application Ser. No. 10 / 025,299 filed on Dec. 19, 2001 priority of which is hereby claimed.FIELD OF THE INVENTION [0002] The invention relates to absorbent articles for use with undergarments or other clothing, such as panty hose, swimsuits, or leotards. In particular, the absorbent articles of the present invention are drapeable. BACKGROUND OF THE INVENTION [0003] Disposable absorbent articles, such as pantiliners, sanitary napkins, interlabial devices, adult incontinence devices and diapers are well known in the art. These articles typically have a fluid permeable body-facing side and fluid impermeable garment facing side. Additionally, such articles may include an absorbent layer for retaining fluids therebetween. [0004] Anatomical adaptation of an absorbent article may increase comfort to the wearer. That is, movement by the wearer may cause the absorbent article to c...
