Abstract: A training urinal attachment mountable to the bowl of a toilet. The attachment includes a resiliently collapsible shell having an intake opening that receives a flow of urine from a standing child and a discharge opening that directs the flow into a collection area of the bowl.

Abstract: Conservation of oily liquid sealant in coaxial odor trap cartridges for waterless urinals is accomplished in the present invention by the addition of a liquid-flow-diverting structure having at least one helical fin encircling the outer surface of the cylindrical partition that extends downwardly from the cartridge top cap. In a preferred embodiment two similar diametrically-opposed helical fins conserve sealant by modifying the otherwise vertical downward flow path to a downward incline that minimizes down-the-drain sealant loss by intensifying recovery of stray traces of sealant that become detached from the main layer of sealant and get swept along with the downward flow of wastewater in the outer chamber during a usage event. The sealant recovery action of the helical fins that takes place in the outer chamber is further enhanced by specially proportioning the cross-sectional flow area of the three chambers in the cartridge to maximize the cross-sectional flow area of the outer chamber.

Abstract: To reduce the barrier sealant amount, the area of a throat (88), communicating an inlet compartment (78) to an outlet opening (64), is made small. Should sealant not be in the throat, wastewater in the throat would be correspondingly small. A snorkel (110) in a discharge section drain tube (98) extends downwards to above the level of the horizontal drain, and allows any air from the external drain to pass to the outlet compartment generally below the ceiling (90) so that, should wastewater cover the opening of the drain tube, such air is permitted to enter into the cartridge and to prevent any syphoning. A three rib channel guide mechanism (100) within the tube guides wastewater flow towards the drain tube center, and away from the drain tube walls to avoid deposit of any sediment contained in the wastewater.

Abstract: A cartridge unit for use with a urinal is disclosed that does not need water to work nor does it use a body of oily liquid sealant as an odor barrier. The odor trap cartridge unit used in this urinal has a spring locking mechanism that works as a valve.

The cartridge unit has a few disks, two main cylindrical devices, a spring, a fastener, an o-ring, and a coupling; these all operate to open and close a spring sealed trap. These are all placed within a unique three-sized shell that supports the entire cartridge and is fitted into a urinal opening. An umbrella shaped part completes the cartridge by protecting its components from violent fluid flow.

Abstract: The invention provides a flush free drain trap system. The trap of the invention may be used in any trap system intended to block a back flow of odors from the waste line. A sealant liquid floats on top of the waste liquid in the trap to block odors. The trap uses one passageway to pass liquids to the sewer line, similarly to a conventional drain system, for preventing overflow and allowing cleaning. A second passageway allows the trap to dispose of small amounts of the waste liquid though an opening and a valve operated by the buoyancy caused by the accumulation of waste liquid in the trap. In normal use, waste liquid is passed to the sewer line without loss of sealant liquid. Furthermore, the performance of the trap is not affected by the evaporation of the waste liquid when the trap is unused.

The container has one or more seals that allows the container to be sealed after use so that leakage of the container after use is minimized or eliminated. Moreover, the container has a generally horizontally disposed downwardly sloping passageway for the passage of urine or other fluids and an angled or arcuately-shaped wall for directing a flow or spray of urine or other fluids into a reservoir for holding the same. Moreover, the container has a window for viewing the contents of the container to determine the quantity of fluids contained therein. Alternatively, the container includes an absorbent material for absorbing the urine or other fluids. The container may be made from a soft, resilient thermoplastic material.

Abstract: In a urine cartridge or wastewater trap, equalized pressures and increased flow rate between its inlet and outlet compartments increases the life of the cartridge. The pressure equalizing is effected by placement of a separator between the two compartments to provide them with substantially equal volumes. The increased flow rate is created by a uniquely configured baffle positioned adjacent a pan at the bottom of the cartridge. The baffle configuration is shaped to provide a constriction that increases the flow velocity of the urine so that the fluid flow effects a channel along the bottom pan and through any solids deposited on the bottom pan. A diverter may be placed above the centrally located entry to the inlet compartment to create a circuitous path for preventing a disturbing impingement of the urine onto the sealant contained in the inlet compartment.

Abstract: The commode-urinal prevents urine-splatters around the commode, and stores extra toilet rolls and flushable funnels. In power-driven commode-urinal, a user activates a sensor; a jaw clamps a flushable funnel to an arm. The arm moves out of dispenser dispensing and suspending the funnel above the commode-bowl. The user urinates through the funnel, which channels urine into the bowl preventing urine-splatters around the commode. After urinating, the user activates the sensor; the jaw retracts releasing used funnel into the bowl. The arm retracts into the dispenser clearing the commode to function unimpeded. Flushing drains away the funnel. In manually-operated commode-urinal, when ready to urinate, the user pulls a funnel from the dispenser. Keeping bottom end of the funnel in middle of the bowl, the user urinates through it. After urinating, the user drops the funnel into the bowl and flushes. The funnels have wet strength, water repellency, but degrade in drains.
