Abstract: A portable restroom includes a thermoformed plastic floor panel that includes integral perimeter side wall portions that can be fastened directly to the side panels of a portable restroom. The top edge of the floor panel side wall portions extends outwardly to fit into a corresponding groove molded into the side panels of the restroom, in a tongue and groove fashion. This tongue and groove arrangement can be angled slightly upward so that the weight of the side panels helps to lock the two parts together. Fasteners further secure the floor panel to the side panels and are located around the perimeter of the floor just below the tongue and groove feature. The floor and side panels can be made of polyethylene plastic, formed by the thermoforming process. The vertical side walls of the molded floor can incorporate gusset features to add structure and rigidity to the floor panel.

Abstract: An inline dispersal valve that can be used with or without a base. One embodiment includes a rotatable member that is rotatable from a fluid stream obstructing condition to an out-of-the-way condition to prevent fluid diversion into the dispersal valve. Another embodiment includes a lever handle for quickly setting the amount of fluid being diverted into the inline dispersal valve. Another embodiment includes an indicator that can be viewed from a position above the inline dispersal valve. Another embodiment includes a cap that can be secured or removed without the aid of tools. Another embodiment includes a clip that allows one to disassemble the inline dispersal valve for servicing. Another embodiment includes a dispensing valve that can be reversed and still properly divert fluid into a dispersant chamber. Another embodiment includes an inline dispersal valve with a bleed valve positioned to allow one to bring the air volume in the dispersant chamber to the proper level.
