    • 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.
    • 公开了一种可生物降解和可马桶冲洗的身体废物收集袋,以及其中这种袋构成可剥离可分离的袋 - 袋系统的内袋的器具和方法。 内袋的壁由超薄的可热封膜组成,其不可渗透人体废物,其包括可塑化的可生物降解的聚酯或外部由可生物降解和水分散性纤维的柔软,多孔,可水解的覆盖层覆盖的共聚酯。 覆盖层和膜以这样的方式弱结合在一起,以避免否则可能由纤维引起的膜中的针孔。 当用作袋式小袋系统的内袋时,选择外袋的熔融温度高于内袋膜的熔化温度,结果是连接外袋的壁的周边热封 两个袋在一起将允许外袋的壁被剥离而不剥离内袋的膜和覆盖层。
