Abstract: A liquid-permeable panel that is of a system toilet for animals and that can prevent urine wetting resulting from torsion or folding over of a pee pad. The liquid-permeable panel covers the excrement containment section of the system toilet for animals. Of the aforementioned panel, the side-surface 1 cm compression deformation load, which is the load necessary for at least 1 cm of torsion to arise with respect to load from the side-surface direction that is perpendicular to the direction of thickness of the panel, is at least 5 N and no greater than 20 N. Preferably, the liquid-permeable panel has a plurality of holes that penetrate the liquid-permeable panel in the direction of thickness, and has as a material corrugated cardboard in which liquid goes through the aforementioned plurality of holes, passing through in the direction of thickness of the aforementioned liquid-permeable panel.

Abstract: A topsheet for body fluids absorbent article having a plurality of liquid-pervious apertures, the topsheet including an upper fibrous layer having a relatively low density and a lower fibrous layer having a relatively high density. Around each of the apertures, the first and second fibrous layers are integrated together so that the topsheet has a density progressively increasing from an upper surface towards a lower surface of the topsheet and has, in the proximity of the lower surface, a density further higher than in the second fibrous layer. The topsheet thus formed improves so that an upper surface thereof can be maintained in a dry state during use of the article having the topsheet.

Abstract: A disposable diaper includes barrier cuffs around wearer's legs. Each of the barrier cuffs longitudinally extends on an inner surface of the disposable diaper and includes a supporting wall section adapted to rise on the inner surface of the diaper and a sealing surface zone which includes a first overhead section extending inwards from the supporting wall section and a second overhead section extending outwards from the supporting wall section. A first elastic member extending along an inner edge of the sealing surface zone in operative association with the first overhead section has an elongation stress higher than that of a second elastic member extending along an outer edge of the sealing surface zone in operative association with the second overhead section. The barrier cuffs thus constructed provide a good fit around a wearer's legs to prevent body fluids from leaking.
