Abstract
Abstract A disposable diaper having an inside surface for direction toward an infant and an outside surface is provided with adhesive tabs, each tab having an adhesive coating on one face thereof. Each tab has a first end portion which is permanently attached to a marginal portion of the diaper outside surface by means of the adhesive coating, and an opposite end portion which is divided longitudinally into a central strip and a pair of marginal strips flanking the central strip. The marginal strips are permanently attached to a marginal portion of the diaper inside surface by means of the adhesive coating. A release layer is releasably adhered to the adhesive coating on the central strip and removable therefrom, whereby the central strip provides a securement means for fastening the diaper about an infant.
