ABSTRACT:
A splash-eliminating urinal contains an outer body and a receptor cavity within the outer body. The receptor cavity contains a rear surface having projecting concave rear walls that converge to form sides of an outwardly-projecting vertical ridge, and two side walls that transition to the rear walls. When a stream of urine is directed onto the rear walls, it adheres by surface tension without causing a splash.
