  • Patent number: 5038721
    Abstract: A system which separates the pet excreta collection, storage and disposal functions wherein each individual component used to perform each of these functions is optimized for its intended purpose. The system of the present invention permits almost indefinite recycling of the substantially nonsorbent, nonclumping granular litter material used by the animal to bury its solid excreta. The combination of the present invention includes a porous filtering member exhibiting a pore size which will readily permit the granular litter material to pass therethrough, yet retain substantially all of the solid animal excreta coming in contact with the fitering member during the filtering operation. A protective member capable of substantially resisting damage when subjected to digging or clawing by animals is secured in superposed relation to and completely overlies the uppermost surface of the porous filtering member.

  • Patent number: 5037416
    Abstract: A disposable absorbent article, such as a diaper, is disclosed. The topsheet of the diaper is elastically extensible and provides a relatively low contact pressure against the skin of the wearer at relatively high elongations. This arrangement provides a diaper topsheet which can be elongated to conform to the shape of the wearer without causing undue discomfort or irritation. The relatively low ultimate contact pressure at relatively high elongation may be accomplished either through a low contact force differential material, or through a material which exhibits stress relaxation over a relatively short period of time. The topsheet may be a laminate having one elastomeric lamina and an inelastic lamina. Also disclosed is a method for making such a laminate.

  • Patent number: 5032122
    Abstract: A loop fastening material having a backing of orientable material and a multiplicity of fibrous elements extending from the backing. The fibrous elements are formed by filaments positioned on the backing and secured to the backing when the orientable material of the backing is in its dimensionally unstable state. The filaments are preferably positioned on the backing parallel to each other and essentially parallel to the path of response of the orientable material. The filaments are intermittently secured to the backing at spaced, fixed regions along the filaments so that each pair of fixed regions defines therebetween an unsecured catching region. Thus, the fibrous elements are formed by the shirring of the filaments at the catching regions when the orientable material is caused to be transformed to its dimensionally stable state such that it is caused to contract or gather along its path of response.

  • Patent number: 5032120
    Abstract: A disposable absorbent article, such as a diaper, is disclosed. The diaper has two lengthwise extending longitudinal marginal portions, each longitudinal marginal portion having two elastically extensible leg cuffs, a barrier cuff and a gasket cuff. The leg cuffs serve to help contain body exudates within the disposable article. Each leg cuff is elasticized to provide a relatively low ultimate contact force against the skin of the wearer at relatively high elongations. This arrangement provides a diaper with leg cuffs which can be elongated to conform to the shape of the wearer, without causing undue discomfort or irritation to the legs of the wearer. The relatively low ultimate contact force at relatively high elongations may be accomplished either through a low contact force differential material, or through a material which exhibits stress relaxation over a relatively short period of time.
