Open the CIPO recordAbstract From the Canadian patent
A one-piece toilet bowl and rim capable of generating superior vortex water flushing action is disclosed. Metering of the volume, flow rate, and directional orientation of the flushing water into, and within the internal rim cavity is developed by two flow passages of different diameters. The angular orientation of the flow passages generates fluid flow within the rim cavity in opposite directions. The flushing water flowing within the rim cavity is angularly discharged through a continuously slotted discharge orifice circumferentially located along the underside of the rim. The angularly discharged flushing water generated superior vortex flushing action within the toilet bowl.
