Abstract
A biodegradable and toilet-flushable body waste collection pouch, and an appliance and method in which such pouch constitutes the inner pouch of a peelably separable pouch-in-pouch system, are disclosed. The walls of the inner pouch are composed of an ultra-thin, heat-sealable film impermeable to body wastes comprising a plasticized biodegradable polyester or copolyester externally covered by a soft, porous, water-disintegratable cover layer of biodegradable and water-dispersible fibers. The cover layer and film are weakly bonded together in such a way as to avoid pinholes in the film that might otherwise be caused by the fibers. When used as the inner pouch of a pouch-in-pouch system, the film of the outer pouch is selected to have a melting temperature higher than that of the inner pouch film, with the result that a peripheral heat seal joining the walls of the two pouches together will allow the walls of the outer pouch to be peeled away without delaminating the film and cover layers of the inner pouch.
