摘要：
A device for a toilet bowl, including a mechanism for holding the toilet rim block to the toilet bowl. The invention further relates to at least one, preferably at least two toilet rim blocks, each having an outer cover and a core, and to a rim block cage including the toilet rim block. The outer cover includes a first composition and the core includes a second composition. Preferably, the first and the second compositions differ from each other by at least one of the following features: different active substances, different concentration but same active substance, and different viscosity. The outer cover partly encloses the core and the core protrudes on at least one face of the toilet rim block right to the surface as a pole and is exposed.
