Absorbent article having a high coefficient of friction backsheet and a self-release tape tab
View Patent ↗The present invention relates to an absorbent article for managing bodily fluids, comprising a high coefficient of friction (“COF”) backsheet and at least one tape tab extending therefrom. The tape tab comprises a minimum amount of pressure sensitive adhesive sufficient to maintain the position of the article when a user's undergarments are away from her body. When the undergarments are near her body, the high COF backsheet acts as the predominant means for maintaining the position of the article due to normal forces exerted by the user's body and undergarments. When the user wants to remove the article from her undergarments, the tape tab provides additional advantages. The user may grasp the tape tab itself for removing the article as an alternative to grasping a portion of the soiled article. In addition the soiled article may be folded or rolled up, and then held in that configuration with the tape tab, for convenient and discreet disposal.
1. An absorbent article, comprising:
a) a liquid permeable cover;
b) a substantially tack-free, backsheet having a static coefficient of friction greater than about 1.0 and at least one tape tab affixed to its outwardly disposed surface; and
c) an absorbent material;
wherein the tape tab has a fixed end, a free end, a first surface, and a second surface opposite the first surface having adhesive and release zones thereon.
2. The article of claim 1 wherein the backsheet has a dynamic coefficient of friction greater than about 0.8.
3. The article of claim 1 wherein the backsheet comprises a substrate having a substantially tack-free, high coefficient of friction coating on its outwardly disposed surface.
4. The article of claim 3 wherein the coating has a static coeffieient of friction of greater than about 1.0 and a dynamic coefficient of friction greater than about 0.8.
