Abstract: A reusable leakproof diaper which is as convenient in use as a disposable diaper and includes a one-or-more layered absorbent rectangular liner attached by strips of liquid impervious material to a liquid impervious outer shell. A closure system, such as snap fasteners, single looped closures, buttons, or hooks is mounted on the outer shell. The sides of the outer shell include elastic strips along the portion of the shell that forms a leg opening when the diaper is in use. The unique design for attaching the inner absorbent liner to the liquid impervious outer shell provides the diaper with improved resistance to leakage.
