Abstract
A disposable diaper is provided with an adhesive closure means in which an elongated flexible strip extends transversely across the diaper along a marginal portion thereof. The strip has a mid-portion which is permanently attached to the diaper, and a pair of end portions. Each end portion has an inward section which has a release coating on the inside surface, and a free end section which has an adhesive coating on the inside surface. The free end section is adapted for folding over upon the inward section and releasably adhering thereto. In one embodiment, the inward section is positioned along a side margin of the diaper so that each free end section, when ready for use, extends beyond an adjacent edge of the diaper. In another embodiment, the entire length of each end portion extends beyond a side edge of the diaper. In both of these embodiments, an elongated separator means may be attached to the free end section to provide a gripper for peeling the free end away from the inward section for fastening the diaper about a baby.
