  • Patent number: 6258435
    Abstract: A disinfecting mat includes a spongy core retaining a liquid disinfectant and a cover completely enclosing the core, where the cover has a top surface with an annular top edge and a top central mat portion that is liquid permeable. The core is contained in a water impermeable frame with a bottom and sides that contain the cover and with an inwardly extending annular lip that extends over at least a part of the annular top edge while leaving the top central mat portion open. The liquid permeable top central mat portion allows the disinfectant to puddle in areas of the top central mat portion that are depressed during use.
