MULTILAYER ABSORBENT ARTICLE
First Claim
1. An article for personal wear in contact with a tissue layer of a wearer and capable of holding its position with respect to the contacted tissue layer while reducing the opportunity for damage to the tissue layer, the article having an outer surface and comprising a body facing engagement surface for contacting the wearer'"'"'s tissue layer, the body facing engagement surface having a first state adapted to inhibit movement of the article with respect to the tissue layer of the wearer, and a second state adapted to enhance movement of the article with respect to said tissue layer, said body facing engagement surface being adapted to transform from the first state to the second state upon application of a force greater than a threshold force, the body facing engagement surface comprising a gripping component and a sliding component wherein the gripping component overlies the sliding component in the first state;
- wherein the static coefficient of friction of the engagement surface in the first state is substantially greater than the dynamic coefficient of friction of the engagement surface in the second state;
the gripping component is disposed for engaging and gripping the tissue layer in the first state until a force greater than the threshold force is encountered which transforms the engagement surface to promote relative sliding motion between the engagement surface and the tissue layer; and
the gripping component includes a body adhesive.

Abstract
An article has a body facing engagement surface for contacting a wearer'"'"'s tissue layer. The body facing engagement surface has a first state adapted to inhibit movement of the article with respect to the tissue layer of the wearer, and a second state adapted to enhance movement of the article with respect to the tissue layer. The body facing engagement surface is adapted to transform from the first state to the second state upon application of a force greater than a threshold force. The body facing engagement surface has a gripping component and a sliding component wherein the gripping component overlies the sliding component in the first state. The gripping component is disposed for engaging and gripping the tissue layer in the first state until a force greater than the threshold force is encountered which transforms the engagement surface to promote relative sliding motion between the engagement surface and the tissue layer.

13. An article for personal wear comprising an engagement surface for contacting a tissue layer of a wearer, the engagement surface comprising a sliding component and a body adhesive overlying the sliding component, the engagement surface having a first state adapted to inhibit movement of the article with respect to the tissue layer of the wearer wherein the body adhesive adheres the article directly to the tissue layer of the wearer, the engagement surface being adapted to transform from the first state to a second state upon application of a force greater than a threshold force, the second state being adapted to enhance movement of the article with respect to the tissue layer to promote relative sliding motion between the article and the tissue layer;
-
wherein the article has an outer surface; the engagement surface is a body-facing surface and opposite the outer surface; and the static coefficient of friction of the engagement surface in the first state is substantially greater than the dynamic coefficient of friction of the engagement surface in the second state. - View Dependent Claims (14, 15, 16, 17, 18)
