Toliet dosing dispenser

The invention relates to metering dispensers for release of a product into a WC bowl of a toilet, comprising a fixing region which is constructed in order to fix the metering dispenser in the region of the toilet, in particular under a WC lid, and a storage container for accommodating the product. Such metering dispensers have the problem that the product can be metered only inaccurately and not very variably. This problem is solved according to the invention in that the storage container is constructed for accommodation of pre-portioned products and a delivery device which is constructed in order to deliver at least one pre-portioned product from the storage container into the WC bowl is provided.
