Abstract
Abstract A disposable diaper is provided with a pressure-sensitive tape fastener. The tape is affixed at one end to the liquid retaining backsheet of the diaper and the other end is superposed on a release liner of a generally conventional design from which the tape may be stripped immediately prior to diaper application. The release liner for the tape overlies a portion of the face of the diaper. A first portion of the release liner is secured to the topsheet of the diaper and a second portion thereof is essentially unattached, providing a means to grasp the liner. At least the portion of the topsheet secured to the release liner is releasably secured to the remainder of the diaper so that it may be removed therefrom (after the soiled diaper is removed from the wearer) by gripping and pulling on the unattached portion of the release liner.
