Abstract
Abstract A disposable diaper having a facing sheet defining a diaper inside surface for direction toward an infant and a backing sheet defining a diaper outside surface is provided with adhesive tabs comprising a backing web and a face web. The backing web is folded over to form first and second anchoring legs which are attached to a marginal portion of the diaper received therebetween. The face web has a fixed end permanently attached to the second anchoring leg, and a free working end provided with a layer of adhesive. The free end is movable from a folded-over storage position, in which the adhesive layer is releasably attached to a release region provided on the outer surface of the first anchoring leg, to a working position in which the adhesive layer is available to secure the diaper about an infant. If desired, the backing and facing webs may comprise an integral elongated tape segment. Secondary fastening means may be provided for refastening the diaper about an infant.
