Abstract: A device for spraying disinfectant foam into the opening of a garbage disposal is described. The device contains an aerosol propellant container and a substantially cylindrical adaptor. The adaptor is integrally formed, with both an upwardly-extending lip section and a downwardly-extending bottom section. The upwardly-extending lip section contains at least three flange portions separated by slots in which movable tabs are disposed. The downwardly-extending bottom section contains an orifice. The upwardly-extending section may comprise a single continuous flange with internal radial ribs.
