Abstract

A disposable diaper having a facing sheet defining a diaper inside surface and a backing sheet defining a diaper outside surface is provided with adhesive tabs having an adhesive-coated face and a non-tacky opposite face. A fixed end of each tab is attached to a side marginal location of the diaper outside surface, and the opposite free end of each tab is adapted for folding back to a position wherein the non-tacky face of the free end is juxtaposed to the non-tacky face of the fixed end. A release means is provided on the diaper outside surface adjacent to the adhesive-coated face of the free end when folded back, and a portion of the diaper bearing the release means is adapted for folding thereover. The tabs are movable from a storage position, wherein the free end of each tab is folded back and a portion of the diaper is folded thereover to releasably adhere the adhesive-coated face of the free end to the release means, to an unfolded working position wherein the free end is available to secure the diaper about an infant and the release means remains on the diaper outside surface where it will not contact the infant's skin.

said diaper having a transverse margin which is provided with a pair of slits defining a middle segment of said transverse margin and flaps flanking said middle segment, each flap being situated next to one of said tape segments;
release means provided on said flaps on said outside surface of said diaper and adjacent to said fixed end of each tape segment for releasably covering the adhesive-coated face of the folded back free end of each tape segment;
and
each flap being adapted for folding over said adhesive-coated face of the folded-back free end of said associated tape segment to releasably adhere said adhesive-coated face of each free end to said release means.
