Abstract
Abstract A disposable diaper having a facing sheet defining a diaper inside surface for direction toward the wearer and a backing sheet defining a diaper outside surface is provided with adhesive tape tabs comprising first and second anchoring portions and an attachment portion. The anchoring portions are attached to the inside surface and the outside surface of the diaper at a marginal portion thereof. One of the anchoring portions is made from elastic web material, and the other anchoring portion is made from inelastic web material. The attachment portion is temporarily attached to the inelastic anchoring portion and adhesively secured to the elastic anchoring portion. In use, the temporary attachment is detached leaving only the adhesive securement of the attachment portion to the elastic anchoring portion to provide an elastic tape tab fastener.
