A disposable dispenser for fluid-soluble chemicals that must be slowly released at prescribed times, and a method of manufacture of the chemical and the dispenser in unitary form. The novel chemical composition has a relatively high melting point which permits it to be cast into a substantially imperforate protective cup in a fluid condition, and thereafter allowed to set, thereby becoming unitary with the dispenser. In one manufacture embodiment, the chemical solidifies around appropriate attaching means in the cup in a ready-for-use position. One embodiment of the article is a dispenser for antiseptic and/or deodorizing chemicals for a urinal. The chemical is protected from direct action of urine by a substantially imperforate, inverted cup in which the chemical is located. A perforated flange serves to support the dispenser cup in the desired location within the urinal while also serving to allow effective drainage of the urine. The fluid soluble chemical is released in desired amounts only at the effective time of flushing by the turbulence of the flush water. The chemical-water solution then uniformly washes and deodorizes the urine receptable to provide protection from odor, bacteria and disease. The chemical is not again released from the dispenser until flushing occurs at a later time.
