Abstract

Means for adding disinfectant or the like to the flushing water of a WC comprise two layers, one of which is deep drawn to form a chamber. The other layer seals the chamber. The layer sealing off the chamber comprises a water-resistant material and is provided on at least one of its two surfaces with print or the like. A lower base portion of the chamber serves to enable the storage of the means in an upright position on a shelf or the like.
