Abstract
A disposable diaper is provided with adhesive tab fasteners having a fixed end secured to the diaper and an extendible free end. A pressure-sensitive adhesive coating is provided on one face of the free end and a partible protective cover means is permanently attached to the adhesive coating. The protective cover is substantially coextensive with the adhesive coating when the free end is in a non-extended storage position, but is parted when the free end and adhesive coating are extended to a working position, thereby making portions of the adhesive coating available for use in securing the diaper about an infant. The size and spacing of the exposed adhesive portions on the free end can be controlled to provide adequate adhesive contact for securing the diaper about the infant, while at the same time providing a free end that can be separated from the diaper after affixation for inspecting or repositioning the diaper, and thereafter refastening the diaper.
