Abstract

The invention concerns a device to dispense active substances into rinse water, especially in toilet bowls, with a container for the active substance, wherein the container has an opening that connects with an essentially plate-shaped distributor, and with a device to hold the distributor on or close to the toilet bowl wall. The distributor consists of two essentially plate-shaped elements. There are intersecting grooves, channels or the like between the plate-shaped elements, and a first group of grooves runs outward from the distributor while the other second group of grooves only runs within the distributor.
