Abstract
Abstract In an article suitable for wiping surfaces which comprises an elongate web substrate impregnated with a liquid composition, migration of the liquid along the length of the substrate is substantially prevented by dividing the substrate into a plurality of individual areas by means of a repeating pattern of liquid- repellent barrier material, for example, wax or certain resins, extending across the whole width of the substrate. This measure prevents fluid loss by capillary action and evaporation when the wet substrate is stored in a dispenser. The wet substrate is preferably used in conjunction with a dispenser having a relatively tight closure, especially one in which the closure is formed by two resilient diaphragms with out-of-register apertures. The wet substrate delivery system may be used, for example, for hand hygiene in hospitals, washrooms or kitchens.
