Abstract
Abstract A reusable infant or adult diaper comprises a fluid absorbent pad on the inner surface of a waterproof, hourglass-shaped, diaper shell. Extending from the rear corners of the diaper shell is a pair of fastener tabs carrying filamentary hook fastener material. Slightly larger strips of filamentary loop material on the inner surface of the diaper shell cover the fastener tabs during washing to protect the filamentary hook material from buildup of lint. Each fastener tab and its cover, assembled to the diaper shell by a single continuous line of stitching and turned to the inside of the diaper, presents a finished edge at a corner of the diaper shell. The diaper is fitted to the infant or adult by wrapping the shell around the pelvic region and coupling the fastener tabs to a pair of strips carrying filamentary loop material and arranged in a V-pattern on the front of the diaper. Several embodiments of the diaper are disclosed, including different mechanisms to fasten the shell and absorbent material to the body of the wearer. Fasteners attached to the diaper may be detachable therefrom. Absorbent material may be sewn into the shell or be floating in the shell between the leg holes of the diaper.
