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 wearer'"'"'s tissue layer, 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 that overlies a 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.

Claims

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 at least about 5% 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.

2. The article as set forth in claim 1 wherein the gripping component is disposed to shield the tissue layer from contact with the sliding component in the first state and is displaced to expose the sliding component for contact with the tissue layer in the second state.

3. The article as set forth in claim 2 wherein the gripping component is deformed upon application of a force greater than the threshold force for exposing the sliding component to the tissue layer.

4. The article as set forth in claim 3 wherein the gripping component is ruptured upon application of a force greater than the threshold force.

5. The article as set forth in claim 1 wherein the sliding component comprises a lubricant.

6. The article as set forth in claim 5 wherein the lubricant is selected from a group consisting of silicone, cyclomethicones, dimethicones, dimethiconol, PEG dimethicone, alkyl silicones, phenyl silicones, silicone phospholipids, silicone gums, silicone oils, silicone waxes, cyclopentasiloxane, dimethicone crosspolymers, and combinations thereof.

7. The article as set forth in claim 1 wherein the static and dynamic coefficients of friction of the engagement surface are selected to inhibit damage to the user'"'"'s tissue layer caused by the body facing engagement surface being in contact with the tissue layer.

8. The article as set forth in claim 1 wherein the static coefficient of friction of the engagement surface in the first state is about 5% to about 90% greater than the dynamic coefficient of friction of the body facing engagement surface in the second state.

9. The article as set forth in claim 8 wherein the static coefficient of friction of the engagement surface in the first state is about 15% to about 70% greater than the dynamic coefficient of friction of the body facing engagement surface in the second state.

10. The article as set forth in claim 9 wherein the static coefficient of friction of the engagement surface in the first state is about 25% to about 50% greater than the dynamic coefficient of friction of the engagement surface in the second state.

11. The article as set forth in claim 1 wherein the article is selected from a group consisting of interlabial pads, incontinence devices, tampons, menstrual pads, diapers, training garments, bandages, drug delivery patches, medical diagnostic equipment attachments, ostomy care products, surgical tape, intravenous tubes, endotracheal tubes, catheters, wound care dressings, breast pads, face masks, and eye patches.

12. The article as set forth in claim 1 wherein the threshold force is selected to minimize cutaneous damage.

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 at least about 5% greater than the dynamic coefficient of friction of the engagement surface in the second state.

14. The article as set forth in claim 13 wherein the body adhesive is disposed to shield the tissue layer from contact with the sliding component in the first state and is displaced to expose the sliding component for contact with the tissue layer in the second state.

15. The article as set forth in claim 14 wherein the body adhesive is deformed upon application of a force greater than the threshold force for exposing the sliding component.

16. The article as set forth in claim 15 wherein the body adhesive is ruptured upon application of a force greater than the threshold force.

17. The article as set forth in claim 13 wherein the sliding component comprises a lubricant.

18. The article as set forth in claim 17 wherein the lubricant is selected from a group consisting of silicone, cyclomethicones, dimethicones, dimethiconol, PEG dimethicone, alkyl silicones, phenyl silicones, silicone phospholipids, silicone gums, silicone oils, silicone waxes, cyclopentasiloxane, dimethicone crosspolymers, and combinations thereof.
