  • Portable urinal apparatus to minimize spillage and method for use
    Patent number: 6588024
    Abstract: A portable urinal has a baffle formed within a container to define a front collection chamber and a back collection chamber. The urinal is filled in a horizontal position, in which liquid is contained in the front collection chamber. The baffle's upper edge terminates a distance spaced from the top wall of the container to define a gap over which the liquid flows into the back collection chamber when the liquid exceeds the capacity of the front collection chamber or when the container is tipped upwardly. The baffle retains the contents in the back collection chamber if the urinal is rotated to hang on a bed rail or tipped back to a horizontal position for subsequent use. The urinal is emptied by turning it over to allow the liquid to flow past the baffle and out the opening.
