Abstract: A portable urinal that includes a container defining a liquid reservoir and a spout extending therefrom. The spout has an inlet for receiving a liquid. A valve assembly is disposed within the spout. The valve assembly has an interior region and an exterior region. The valve assembly includes a sidewall and one or more sealable openings for permitting flow of a liquid into the reservoir, while resisting undesired flow of the liquid out of the reservoir. The openings defining the line between the interior region and the exterior region. The valve assembly sidewall has a shaped contour structured to direct liquid flow into the openings.

Abstract: A portable male urinal assembly includes a conventional portable male urinal, having a urine receiving reservoir and a spout extending therefrom with an inlet in the spout for receiving the urine, and a urinal attachment having a valve assembly contained therein being secured in fluid communication to the inlet of the spout. The urinal attachment may be secured to the inlet of the spout either by friction fit, snap fit or threads securing the attachment to the inlet. The valve assembly includes a valve element, a hinge pin and a torsion spring for biasing the valve element into position. The urinal attachment may be composed of a bendable resilient material and the reservoir may be composed of a flexible material.

Abstract: A portable male urinal includes a urine receiving reservoir having a spout extending therefrom with the spout having an inlet for receiving urine. A valve assembly is provided within the spout for permitting flow of urine into the reservoir while resisting backflow of the urine following use of the urinal. The valve assembly may include a valve element, a hinge pin and a spring for biasing the valve element into position. Alternatively, the valve assembly may include a support member secured to the spout along with a flexible leaf member partially attached to the support member. The spout may be composed of a bendable resilient material and the reservoir may be composed of a flexible material.
