Abstract
Abstract An individualized separability member is used in combination with the adhesive portion of a closure tab on a disposable diaper to allow separation of the closure tab from the diaper surface and re-fastening to the diaper. The separability member includes a strip of material having a non-adhesive surface with adhesive release areas on the ends thereof for mating with the adhesive portion of the tab. The other surface is adhesively treated for fastening to the diaper. After fastening, the adhesive tab is detachable from the separability member by peeling the two apart.
