Abstract
Abstract A portable urinal for women comprises: a rigid cup-shaped member for receiving urine, having an upward projection at one end and a spout extending from the opposite end for discharging urine in a directable stream, side walls therebetween having recessed portions; a flexible membrane covering the recessed portions of the side walls and having an upper body-sealing rim; and, at least two braces spaced from one another and extending between upper rims of the rigid recessed side walls. The projection is effective for positioning the urinal and enabling urine to enter the cup-shaped member without body obstruction. The flexible membrane is effective for preventing leakage during use and for wiping urine traces from the body after use. The braces are effective for preventing body contact with urine in the cup-shaped member during use. The portable urinal has a particularly flat, slim profile enabling use while standing and while substantially clothed.
