Claim 18:
19. The waterless toilet of claim 18, wherein said channel bottom wall has a channel wall bottom surface, additionally comprising an odor containment flap secured to said channel wall bottom surface and protruding inwardly to form an air admitting gap with said downwardly protruding channel inner side wall, said odor containment flap being positioned directly above said toilet bowl rim, wherein said tubular liner passes between said toilet bowl rim and said odor containment flap as it feeds into said bowl;
such that, as said blower draws air from within said looped channel and delivers the air into said discharge duct, air is drawn into said looped channel from the interior of said toilet bowl through said air gap, and said odor containment flap inhibits liquids from entering said looped channel and prevents air back-flow into said toilet bowl.
