Cartridge apparatus for urinal

Abstract

A cartridge apparatus for use with a urinal (e.g., a waterless urinal) is configured to be received at least partially within a cartridge housing associated with the urinal bowl thereof. The cartridge apparatus includes a cartridge top member having at least one opening configured to allow urine in a urinal bowl to pass into the cartridge apparatus and a fluidless cartridge trap connected to the cartridge top member that is normally in a closed state to prevent gases (e.g., sewer gases or other odors) from exiting from a cartridge housing and that is in an open state to allow urine to pass therethrough when urine is received in the cartridge apparatus through the cartridge top member. A urinal apparatus with which the cartridge may be used may include a cleaning apparatus for use in disinfecting and/or deodorizing the urinal apparatus.
