Patent ID: 8256038

Claim:
A urinal block for use in a conventional water-based urinal where the water has been shut off, the urinal block comprising: a first block portion comprising about forty to sixty percent of the urinal block, the first block portion having a first portion composition substantially similar to a conventional, non-paradichlorobenzene block used in water-based urinals for deodorizing during each flush; a second block portion comprising about forty to sixty percent of the urinal block, the second block portion having a second portion composition comprising: a non-paradichlorobenzene block portion; an odor counteractant gel wherein the odor counteractant gel is present in an amount of about 15% or more by weight of the second block portion; and a bacterial culture gel wherein the odor counteractant gel and the bacterial culture gel are blended into the non-paradichlorobenzene block portion; and a liquid-pervious and liquid-insoluble layer covering at least the second block portion wherein the layer is configured to allow a urine stream to penetrate through to the second block portion while preventing splashing of dissolved components of second block portion that causes unsightly stain lines in the conventional water-based urinal since the water has been shut-off and no water is being used to flush the urinal.
