Abstract
Abstract An improved diaper to allow fecal materials both solid and semi-solid to be retained away from the body. It includes a water impervious outer layer, a water retention or absorption intermediate layer and an inner or inside layer which is water pervious. The inner layer has an anal opening for waste passage. Immediately below the anal opening in the intermediate layer is an oval shaped solids cavity. Solid waste material from the baby will be deposited in this cavity and may extend in the space between the intermediate layer and the outer layer. The outer layer has a pleat which is aligned with the solids cavity to give more room for waste products. A water soluble cover, which disintegrates in water, may be provided for the solids cavity of the intermediate layer.
