Urinal deodorizer block (nonfiction)

Urinal deodorizer blocks (also called urinal cakes, para blocks, urinal mints, urinal pucks, urinal peons (pee-ons), urinal biscuits, urinal cookies, hockey pucks, toilet pucks, toilet lollies, trough lollies, or urinal donuts) are small disinfectant blocks found in urinals.

The purpose of these blocks is to disinfect, reduce odors, or mask odors of restroom urinals.

They are placed above the urinal drain, often in the confines of a small plastic trap (urinal screen) that prevents their loss down the drain when they dissolve to a small size.
