Abstract
Abstract A disposable diaper adhesive closure in which an adhesive tab permanently attached to the diaper has a releasable cover strip on its adhesive surface and the cover strip remains permanently attached to the diaper, thus eliminating the need for disposal of the cover strip by the consumer when the diaper is applied. In one embodiment, the cover strip is attached to the plastic film backing sheet of the diaper. In a second embodiment, the cover strip is attached permanently to the terminal portion of the adhesive tab end attached to the backing sheet. With either embodiment, the cover strip forms a loop into which the user can place his finger and pull to remove the cover strip from the adhesive surface of the tab which is to be pressed against a juxtaposed region of the diaper backing sheet so as to secure the diaper about the baby in conventional fashion. The cover strip remains secured to the diaper.
